The technical advantages include the multiplicity of individual objects in a single tissue section that can be separately evaluated and the ease with which multiple specimens can be tested simultaneously. As the average tissue section is extremely thin, numerous determinations are possible on a single small sample of tissue. The disadvantages include the difficulties of quantitation, the limitations imposed by solubility, and a current insufficiency of dependable methods. 

Tissue carbohydrates must be kept undissolved and preferably unchanged during the processes of histologic fixation, section-cutting, and chemical treatment. Any solution of the original, intermediary, or final products of tissue carbohydrates defeats their accurate localization in tissues and cells. The reaction products of microchemical methods must be highly colored or black in order to be seen with the microscope. Reproducibility and confirmation by alternative methods are the usual tests for satisfactory localization.

Unfortunately, in establishing national and international standards for organic production, the emphasis has shifted from the purpose and principles of organic farming to the specific inputs, practices, and methods that tend to characterise organic farms. 

More than rights or privileges, participation in the ATS involves shouldering important responsibilities. The solemn recognition of some of these burdens was renewed on the occasion of the conclusion of PEPAT. The ATCPs have a special responsibility to ensure that all activities in Antarctica are consistent with the purposes and principles of the Antarctic Treaty. The development of a comprehensive regime for the protection of the Antarctic environment and dependent and associated ecosystems is in the interest of the mankind.

China has consistently stood for the complete prohibition and thorough destruction of all chemical weapons end their production facilities. The Convention constitutes the legal basis for the realization of this goal. China therefore supports the object and purpose and principles of the Convention. 

II. The object and purpose and principles of the Convention should be strictly abided by. The relevant provisions on challenge inspection should not be abused to the detriment of the security interests of States Parties unrelated to chemical weapons. Otherwise, the universality of the Convention is bound to be adversely affected.

Friendly Relations Declaration Resolution 2625 from 1970, also called the Friendly Relations Declaration, was passed without a vote in the UN General Assembly. It clarifies the purposes and principles of the United Nations. While General Assembly resolutions are not binding and only an indicator of the political discussion, based on the circumstances of its passing, it has been convincingly argued to reflect international custom, state practice or possibly ius cogens...
