Hemoglobin is the specific protein of red blood cells. Those cells in which hemoglobin synthesis is initiated are the earliest cells that can presently be considered to be committed to erythropoiesis. In order to identify such early cells electron microscopically, we have made use of the peroxidatic activity of hemoglobin by reacting the marrow of erythropoietically stimulated guinea pigs with diaminobenzidine (DAB). The reaction product appeared as a diffuse and amorphous electron opacity throughout the cytoplasm of reactive cells. The detection of small density increases of such a diffuse nature required an analytical method more sensitive and reliable than the visual examination of micrographs. A procedure was therefore devised for the evaluation of micrographs (negatives) with a densitometer (Weston Photographic Analyzer).

Although sections of frozen salt solutions have been used as standards for x-ray microanalysis, such solutions are less useful when analysed in the bulk form. They are poor thermal and electrical conductors and severe phase separation occurs during the cooling process. Following a suggestion by Whitecross et al we have made up a series of salt solutions containing a small amount of graphite to improve the sample conductivity. In addition, we have incorporated a polymer to ensure the formation of microcrystalline ice and a consequent homogenity of salt dispersion within the frozen matrix. The mixtures have been used to standardize the analytical procedures applied to frozen hydrated bulk specimens based on the peak/background analytical method and to measure the absolute concentration of elements in developing roots.

This paper presented a novel analytical method for calculating magnetic field in the slotted air gap of spoke-type permanent-magnet machines using conformal mapping. Firstly, flux density without slots and complex relative air-gap permeance of slotted air gap are derived from conformal transformation separately. Secondly, they are combined in order to obtain normalized flux density taking account into the slots effect. The finite element (FE) results confirmed the validity of the analytical method for predicting magnetic field and back electromotive force (BEMF) in the slotted air gap of spoke-type permanent-magnet machines. In comparison with FE result, the analytical solution yields higher peak value of cogging torque.

The research objective describes an integrated marketing communication strategy in developing Sakura Syariah Hotel to see a comprehensive marketing communication strategy. Hotel Sakura Syariah is a 3-star syariah concept hotel which has 70 rooms. The analytical method uses the 7P (marketing mix) approach. The research results to increase the number of guests staying the strategy consisted of products, which offer a sharia concept with various types of representative rooms. Pricing, using the appropriate price preferences. Place, hotel location that is close to the center of the district capital and easy access. Promotion, with direct selling in accordance with local government and private selling by participating in various marketing events, sales proposals and advertising. People, conduct trainings to improve human resource capabilities. Physical evidence, a physical building that has Sharia characters and is supported by fairly good technology. Process, reservation service is quite fast and excellent. The development of this Sayriah hotel must be supported by related parties, especially the local government in order to increase the number of hotel guests
