Physiological features of amylase synthesis and excretion are considered in the article, presence of other sources of amylase synthesis different from pancreas and salivary glands is emphasized. Definitions of hyperenzymemia and macroamylasemia (MAE) are given. MAE is a state characterized by presence of circulating complexes of normal serum amylase with protein or carbohydrates in blood. There are 3 types of MAE: first — classical (constant hyperamylasemia, decreased amylase level in urine, high blood concentration of macroamylase complexes); second — hyperamylasemia with slightly decreased amylase activity in urine, macroamylase/normal amylase ratio is less than in the first type; third — normal blood and urine amylase activity, low macroamylase/normal amylase ratio. Pathogenesis is explained by connection of blood amylase and acute phase protein in different inflammatory, infectious diseases, malabsorption. MAE clinical manifestations could be absent, sometimes abdominal pain is possible. Hyperamylasemia and reduced urine amylase activity are typical. MAE diagnostics means determination of macroamylase complexes in blood (chromatography, calculation of the clearance ratio of amylase and creatinine). The article presents clinical cases describing extra-pancreatic MAE in women with malignant ovarian lesions. The question of expediency of thorough diagnostic examination in asymptomatic MAE is raised, which may turn out to be a symptom of cancer. The lack of specific treatment for MAE is emphasized.

The investigation of which this paper gives a brief summary relates to serum-albumin rather than to serum-globulin, and the experiments may be arranged in two categories: first, those relating to heat-coagulation; and secondly, those relating to the action of certain salts upon the proteids of blood-serum. The apparatus used for the determination of the temperature of the heat-coagulation of proteids was not that which has been usually employed for the purpose, and which consists of two beakers contain­ing water, one within the other, and heated gradually over a sand-bath; the substance under investigation being placed in a test-tube contained within the inner beaker. The chief objection to that method is that the rise of temperature in the water in the beakers takes place with extreme slowness, so that changes are apt to occur in the proteid during the experiment. To meet this difficulty an apparatus was devised by Professor Schäfer, which was found to be I extremely easy to use, and of which the great advantage consists in f the readiness with which a constant temperature is maintained for a s considerable time. It may be briefly described thus: the liquid of which one wishes to determine the temperature of coagulation is placed in a test-tube in sufficient quantity to cover the bulb of a thermometer put into it; the test-tube is placed in the neck of a flask containing water; this water is kept at the desired temperature by the following means. It is in the first place kept constantly running, entering by one tube and leaving the flask by another tube inserted as a T-piece in the upper part of the neck. The water is warmed by passing it through a coil of tubing contained in a vessel in which water is kept constantly boiling. By regulating the rate at which the water flows through this apparatus the desired temperature is maintained.

PT. Lafarge Cement Indonesia (LCI) Lhoknga, have produced their products to reach 1.78 million tons per year onwards. PT. Lafarge Cement Andalas (LCI) Indonesia Lhoknga has port facilities themselves in Lhoknga, also some bag terminal contained in Lhokseumawe, Belawan, Batam, and On the distribution of bagged cement in Lhoknga packing stasiun is not maximized because of the overall quota provided only 60% per month which taken by the distributor of the sales target. Distribution scheduling methods do by using Visual Basic 2010 facilitated program Semen RF Ugha 68. An initial simulation results can be used to analyze the amount of the distribution and the distribution shifts per day with a certain amount of quota that is not the same each month or per day depending on the number of working days will be used. In the program Ugha Cement RF 68 just counting the number of quota per month, per day, the amount of the effective time, the number of maneuvers the truck, and the number of bags per day to be distributed. The final results of how the amount of the actual time required to distribute the total quota Based on the results waiting time machine the bag terminal caused by several things including, the quota system, scheduling less well planned, distributors do not consistently take the cement appropriate amount of quota per day that has been allocated, and the determination of the day working up to 30 working days to reach the number of hours worked two shifts.Keywords: PT.

Abstract Starch is determined in various materials such as feeds, grains, cereals, grasses, and feces by the combination of some existing techniques plus new methodology. Samples are extracted with aqueous alcohol and hydrolyzed with HCl; the resulting glucose is measured with a glucose oxidase enzyme system. The actual handling operations, including troublesome nitrations and constant temperature baths, are minimized or eliminated.

When attempts are made to use thin film anemometers in airflow to measure fluctuating velocity it is found that the dynamic sensitivity cannot be obtained from a steady-flow calibration. It is found that the dynamic sensitivity is considerably less than that predicted by static calibration and that the sensitivity is frequency-dependent. It is shown that thermal feedback from the substrate, on which the gauge is mounted, to the heated element is responsible for the variation of sensitivity with frequency, despite constant-temperature operation of the probe, and this variation is examined theoretically and experimentally.

The reaction of casein and of fresh and deteriorated milk protein with nitrous acid has been followed at constant temperature for 4 hr. in the manometric apparatus of Van Slyke, and simplified procedures suggested whereby the method can be utilized for investigation of the deterioration of the protein of separated milk powder during storage.Technical assistance in this work was given by Mr L. J. Parr: The work was carried out as part of the programme of the Food Investigation Board of the Department of Scientific and Industrial Research.
