Air pollution causes significant health and economic problems in the Philippines. [21] An estimated 66,000 deaths annually have been directly linked to air pollution. [22] The Department of Environment and Natural Resources is tasked with implementing the Clean Air Act of 1999 to monitor and prevent air pollution in the country. [23]
Agricultural water management in the Philippines is primarily focused on irrigation. The country has 3.126 million hectares of irrigable land, 50% (1.567 million hectares) of which already has irrigation facilities. 50% of irrigated areas are developed and operated by the government through the National Irrigation System (NIS). 36% is developed by the government and operated by irrigators ...
Since the EPA first started regulating clean air in the 1970s, emissions of the most common air pollutants have dropped by almost 80%. But around Houston, there's still a long way to go.
Surface nuclear magnetic resonance (SNMR), also known as magnetic resonance Sounding (MRS), is a geophysical technique specially designed for hydrogeology.It is based on the principle of nuclear magnetic resonance (NMR) and measurements can be used to indirectly estimate the water content of saturated and unsaturated zones in the earth's subsurface.

Aquatic environments are especially impacted by alkaline precipitation. Because alkaline precipitation can be harmful to the environment, it is important to utilize various methods such as air pollution control, solidification and stabilization, and remediation to manage it. [1] The impact of alkaline residue in the environment.

In NMR studies of protein dynamics, the nitrogen-15 isotope is the preferred nucleus to study because its relaxation times are relatively simple to relate to molecular motions. This, however, requires isotope labeling of the protein. The T 1 and T 2 relaxation times can be measured using various types of HSQC-based experiments. The types of ...
