Brief introduction to soil organic matter (SOM) Soil organic matter (SOM) is one of the most important components of soil formation, being a combination of specific and non-specific organic compounds. SOM is formed during the decomposition and humification of biogenic residues (Semenov and Kogut, 2015). The chemical structure of soil organic matter is complex and not fully known. Traditionally, the SOM content in soils is estimated by determining the concentration of carbon associated with organic compounds (Corg) and multiplying Corg by a factor of 1.724. The value of the coefficient was established from the condition that Carbon makes up nearly 58% of SOM. However, the carbon content of SOM may vary depending on the type of soil. Consideration of the possible variation in the organic matter composition predicts a range

  • EBF Exemption Request – Approval Letter and Annex
    UNITED NATIONS NATIONS UNIES POSTAL ADDRESS - ADRESSE POSTALE: UNITED NATIONS, N.Y. 10017 CABLE ADDRESS - ADRESSE TELEGRAPHIQUE: UNATIONS NEWYORK 29 June 2021 Dear Mr. Linton, On behalf of the Security Council Committee established pursuant to resolution 1718 (2006), I have the honour to refer to the letter dated 16 June 2021 from the Counsel to the Eugene Bell Foundation (EBF), conveying to the Committee an exemption request pursuant to paragraph 25 of resolution 2397 (2017) to engage in humanitarian activities in the DPRK, in particular to authorize the shipment of supplies necessary to maintain and expand EBF’s ongoing diagnosis and treatment program for multi-drug resistant tuberculosis and extensively-drug resistant tuberculosis in the DPRK, in accordance with Implementation Assistance Notice No. 7. I also note the request for a longer timeframe for the exemption, given the continued challenges related to the shipment of goods as a result of the COVID-19 pandemic. I have the further honour to inform you that, following due consideration, the Committee has decided to approve the requested exemption in the abovementioned letter, in accordance with paragraph 25 of Security Council resolution 2397 (2017), as well as an extended timeframe for the exemption on an exceptional basis, to transfer the items and services outlined in the letter within the next twelve months, which is enclosed in this letter as an attachment. The Committee recommends that, to the best extent practicable, the items be consolidated into three shipments or less, with a view to increasing efficiency of shipping and custom clearance. The Committee reiterates that the sanctions measures imposed by the Security Council through its resolutions with respect to the DPRK are not intended to bear a negative impact on the people of the DPRK, and the note verbale it issued to all Member States, as well as its press release SC/13113 of 8 December 2017, offer clarifications as regards humanitarian aid to the DPRK.

  • Beaker : a Simple Container for Stirring, Mixing and Heating Liquids Commonly Used in Many Laboratories
    Beaker : A simple container for stirring, mixing and heating liquids commonly used in many laboratories. It is generally cylindrical in shape, with a flat bottom. Erlenmeyer flask : The type of laboratory flask which features a flat bottom, a conical body, and a cylindrical neck.(The tapered sides and narrow neck of this flask allow the contents of the flask to be mixed by swirling, without risk of spillage, making them suitable for titrations.) Volumetric flask(measuring flask or graduated flask) : A piece of laboratory glassware, a type of laboratory flask, calibrated to contain a precise volume at a particular temperature. It is used for precise dilutions and preparation of standard solutions. These flasks are usually pear-shaped, with a flat bottom, and made of glass or plastic. The neck of the volumetric flasks is elongated and narrow with an etched ring graduation marking. Graduated cylinder(measuring cylinder or mixing cylinder) : A piece of laboratory equipment used to measure the volume of a liquid. Graduated cylinders are generally more accurate and precise than laboratory flasks and beakers. However, they are less accurate and precise than volumetric glassware, such as a volumetric flask or volumetric pipette. Pasteur Pipette(droppers or eye droppers) : Be used to transfer small quantities of liquids. They are usually glass tubes tapered to a narrow point, and fitted with a rubber bulb at the top. Burette(buret) : A device used in analytical chemistry for the dispensing of variable, measured amounts of a chemical solution. A volumetric burette delivers measured volumes of liquid. Petri dish : It is a shallow cylindrical glass or plastic lidded dish that biologists use to culture cells.
