คนเราส่วนใหญ่รู้สึกวิงเวียนศีรษะและปวดศีรษะในบางครั้ง โดยปกติสาเหตุมาจากเชื้อไวรัสหรือไข้หวัดใหญ่ตามฤดูกาล น่าเสียดายที่ผู้คนจำนวนมากมีอาการที่ไม่สามารถอธิบายได้ ในกรณีที่เลวร้ายที่สุด การไปพบแพทย์ของคนหลายคนยังไม่ได้รับคำอธิบายเกี่ยวกับอาการของตนเอง ส่งผลให้อาการวิงเวียนศีรษะดำเนินต่อไปและทำให้ผู้คนใช้ชีวิตลำบากในแต่ละวัน สาเหตุอาจเป็นคุณภาพอากาศภายในอาคารหรือไม่

The global food system is responsible for approximately one-quarter of the worlds greenhouse gas emissions especially methane (CH4) and nitrous oxide (N2O). CH4 has 25 times and N2O 296 times higher GHG effects than that of CO2, which leads to the secondary atmospheric contamination. Read further to learn how GASERA ONE analyzers help reduce greenhouse gas emissions.Furthermore, N2O emission have a negative effect on nitrogen conservation and on agricultural value. Therefore, it is important to find an economical and practical way to reduce GHG emissions in the food production processHow the farmers can tackle this challenge and reduce their greenhouse gas emissions and improve their livelihood? Accurate measurements and monitoring of the emissions yielding good data makes smart farming!

The DigiBlock heating surface is made of graphite or aluminum alloy protected by PTFE coating and can accommodate as many as 54 graduated tubes and operates from room temperature up to 450°C. The DigiBlock complies with the highest international standards to perform EPA approved methods. The DigiBlock use low cost, disposable digestion tubes to speed up. The LabTech PP digestion tubes contain no detectable background contaminants and do not require washing with acids prior the use. Different sizes and disposable tubes are available to meet any laboratory needs.

When people talk about greenhouse gas (GHG) emissions, the focus is usually on carbon dioxide or methane. These two gasses make up about 90% of the GHGs that cause climate change. But there are a number of others that climate scientists monitor. Among them is sulfur hexafluoride, or SF6, a colorless, odorless gas used as an insulator in power substations. Though its prevalence in the atmosphere is small, it has the potential to make an outsized impact. Thats because it is the most potent GHG, with 23,500 times the global warming potential of carbon dioxide.Researchers in the power and energy sector where it is used have devoted significant effort to finding replacements.

Principles Various gas sensors measure the gas concentration inside the measuring head. Software calculates the flux directly on site. Accurate GPS module determines the exact location of the measurement.

Monitoring mercury levels in ambient air is a crucial component of environmental protection, yet its widespread implementation has been fettered by the limited amount of global monitoring sites

Since their domestication millennia ago, nonhuman animals have been considered property. As such, they are often identified using various methods, including branding, that indicates their belonging to a certain ranch. Branding is used as a property stamp identifying the stockbreeder as the owner of the animal. By branding the animals, ranch owners are expressing the animals’ legal condition as mere things, or as slaves. There are many types of branding, including:
