The supply of these elements in the soil has become limited in some areas as a result of the introduction of high yielding varieties, better and more intensive cropping practices, and increased use of high analysis fertilisers. In some cases, the ob- served deficiencies of these micronutrients have been man- made due to addition of interfering elements for other pur- poses. For instance there is the copper induced iron chlorosis, copper being introduced as agricultural sprays and the phosphorus induced iron and zinc deficiencies, phos- phorus being introduced to meet the phosphorus requirement of farm crops. How to minimise such interactions and the problems of keeping these micronutrient elements available to the plants when applied to the soil have been the sub- ject of intensive researches.

Pacific Northwest Forest and Range Experiment Station, Portland, Oregon. Twelve different nitrogen (N) fertilizer treatments were tested on potted western hemlock (Tsuga heterophylla (Raf. ) Sarg.) seedlings. Fertilizers affected soil N and pH, and growth and foliar chemical com­ position of seedlings. Ura plus N-Serve and sulfur-coated urea appear more promising for promoting growth than other fertilizers tested. Results, however, do not explain reported variability in response of hemlock stands to N fertilization. Keywords: Nitrogen fertilizer response, seedling growth, western hemlock, Tsuga heterophylla. RESEARCH SUMMARY Research Paper PNW-267 1980 The following fertilization treatments were applied in the spring to potted, 4-year-old western hemlock (Tsuga heterophylla (Raf.

  • Vaccine Excipient Table
    Vaccine Excipient Summary Excipients Included in U.S. Vaccines, by Vaccine In addition to weakened or killed disease antigens (viruses or bacteria), vaccines contain very small amounts of other ingredients – excipients. Some excipients are added to a vaccine for a specific purpose. These include: Preservatives, to prevent contamination. For example, thimerosal. Adjuvants, to help stimulate a stronger immune response. For example, aluminum salts. Stabilizers, to keep the vaccine potent during transportation and storage. For example, sugars or gelatin. Others are residual trace amounts of materials that were used during the manufacturing process and removed. These can include: Cell culture materials, used to grow the vaccine antigens. For example, egg protein, various culture media. Inactivating ingredients, used to kill viruses or inactivate toxins. For example, formaldehyde. Antibiotics, used to prevent contamination by bacteria. For example, neomycin. The following table lists substances, other than active ingredients (i.e., antigens), shown in the manufacturers’ package insert (PI) as being contained in the final formulation of each vaccine. Note: Substances used in the manufacture of a vaccine but not listed as contained in the final product (e.g., culture media) can be found in each PI, but are not shown on this table. Each PI, which can be found on the FDA’s website (see below) contains a description of that vaccine’s manufacturing process, including the amount and purpose of each substance. In most PIs, this information is found

These include the development and maintenance of the national standards of measurement and the provision of means and methods for making measurements consistent with these standards; the determination of physical constants and properties of materials; the development of methods and instruments for testing materials, devices, and structures; advisory services to government agencies on scientific and technical problems; in- vention and development of devices to serve special needs of the Government; and the development of standard practices, codes, and specifications. The work includes basic and applied research, development, engineering, instrumentation, testing, evaluation, calibration services, and various consultation and information services. Research projects are also performed for other government agencies when the work relates to and supplements the basic program of the Bureau or when the Bureau’s unique competence is required. The scope of activities is suggested by the listing of divisions and sections on the inside of the back cover. Publications The results of the Bureau’s work take the form of either actual equipment and devices or pub- lished papers. These papers appear either in the Bureau’s own series of publications or in the journals of professional and scientific societies.

  • General Properties of the Alkaline Phosphates: - Major Food and Technical Applications
    Phosphorus Research Bulletin Vol. 15 (2004) p. 85-94 General Properties of the Alkaline Phosphates: - Major Food and Technical Applications P.HOURANT Deputy Business Line Manager, Prayon S.A., Business Unit Phosphates, Rue Joseph Wauters, 144 4480 Engis, Belgium; E-mail: [email protected] INTRODUCTION The alkaline phosphates are used for many food and technical applications. Phosphates have two characteristics that explain their four main properties: buffer agent, sequestering power, dispersing power and water holding capability. Those properties allow phosphates to be used in many food and technical applications. The main food applications are meat and seafood processing, baking and processed cheese, but others such as cereals, French fries, fruits and vegetables, beverages, noodles and so on also may need the use of phosphates. On the technical side, the main applications are the detergent products, the water treatment and the metal treatment. As for the food, many other applications require phosphates such as ceramics, bone china, paper and paints,... In meat products, phosphates salts interact in a unique way to bind water with proteins and improve the tenderness in meats. Treated products will maintain their juicy appearance as well as their natural nutritional properties texture and colour. In fish and seafood products, phosphates salts allow the retention of the natural juices of frozen fish fillets, prawns, shrimps, scallops and other seafood. Phosphates also help prevent the build-up of struvite crystals in tinned tuna and crabmeat. In processed cheese, phosphates are crucially important in the production of processed cheese. These products ensure a homogeneous and uniform melt of raw cheese and product stability.
