Abstract A visual method is presented that enables the analyst to isolate clumps of mold from dark solutions and from colored and irregular bottles and to examine the material microscopically. The solutions to be examined are passed through a glass tube for visual examination, and any observed extraneous material is deposited directly onto a slide. Physical characteristics are not altered, and all visible mold clumps can be accurately counted and measured.

Wooden Structures

The process of evaluating wooden structures, which is gaining great popularity these days, is examined. In view of the fact that the main development of the countryside took place during the Soviet era, by our time, wooden structures of the last century have become unusable and cannot be used for their intended purpose. The results of a visual examination of wooden structures of the feldsher-midwife station located in s. Lopatino, Saratov region. All wooden structures of the object were examined, measurements of the found damages were made. During the examination, a visual method with photo fixation was used. The analysis of the terrain in which the object is located, in order to more accurately obtain the result of the origin of the identified damage. The types of studies considered, as well as their assessment, can be used for surveys of other buildings with similar structural damage. The conducted studies will help to be used as one of the options for technical solutions necessary for the reconstruction of the facility.

The present study was carried out to investigate the reproductive activity of mature buffalo bull and months changes on the testes and epididymis. Two hundred and fifty ( 250) testes of mature buffalo bull were collected from the slaughter house east Kerbalaa city from December/2010 to September2011 ,visual examination of the male before slaughter was done to make sure it is healthy. Semen was collection from the left testes before slaughtering via aspiration from the tail of epididymis and make semen evaluation individual motility, viability, concentration and abnormalities. After slaughtering the right testes measuring the length and width then carefully dissected the epididymis and measuring the length and weight of epididymis and measuring the weight of testes, diameter and weight of epididymis tail. The present results demonstrated increased (P<0.05) significantly in weight, length and width in testes in March and April, and increased significantly in length, weight of epididymis, diameter and weight of epididymis tail in April and May. The individual motility higher significantly P<0.05 in December January and April, and the live sperm higher significantly in April, March and May, and the concentration higher significantly in April , May and March, while the abnormalities was higher significant in August ,July and September. From all these results conclusion reproductive activity of buffalo bull and semen physical characteristics increased in the moderate and cold months and decreased in hot months .The increased of ambient temperature in hot months lead to disturbance in reproductive activity but don’t stopped it .

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).

HeLa cells were grown for 2-3 days in EAGLE'S minimum essential medium with 10% calf serum (S-MEM; Seromed, München) and then incubated for 24 hours in serum free medium (MEM). After detaching the cells with a solution of 0. 14 % EDTA and 0. 07 % trypsin (Difco, 1 : 250) they were suspended in various solutions (S-MEM = control, MEM, buffered salt solutions with or without Me++ions, 0. 9 % NaCl solution) and allowed to settle on glass tube slips (Leighton-tubes). After 5, 10, 15, 20, 25, 30, 1 45, 60 minutes 2, 3, 4, 5 hours cells were prepared for scanning electron microscopy as described by Paweletz and Schroeter. The preparations were examined in a Jeol SEM (JSM-U3) at 25 KV without tilting.The suspended spherical HeLa cells are able to adhere to the glass support in all solutions. The rate of attachment, however, is faster in solutions without serum than in the control. The latter is in agreement with the findings of other authors.

Overall Performance

The electron source is the most important component of the Scanning electron microscope (SEM) since it is this which will determine the overall performance of the machine. The gun performance can be described in terms of quantities such as its brightness, its source size, its energy spread, and its stability and, depending on the chosen application, any of these factors may be the most significant one. The task of the electron gun in an SEM is, in fact, particularly difficult because of the very wide range of operational parameters that may be required e.g a variation in probe size of from a few angstroms to a few microns, and a probe current which may go from less than a pico-amp to more than a microamp. This wide range of operating parameters makes the choice of the optimum source for scanning microscopy a difficult decision.Historically, the first step up from the sealed glass tube ‘cathode ray generator’ was the simple, diode, tungsten thermionic emitter.

We have indicated that the lighter atoms such as oxygen in Cu2O can be observed at the specimen with optimal thicknesses based on the dynamic effect of electron diffraction(1). This rule in principle should hold good for the imaging of other lighter atoms such as sulphur atom in Cu2S. However, this point of view needs further experimentally confirm because up to now only oxygen atoms have been observed in Cu2O and a series of new suboxides of copper and nickel (2). In addition, the sulphur atom is much heavier than oxygen one though is still lighter than copper atom. In the present report we provide such a confirmation.The crystallites of Cu2S shown in Fig.l were obtained by sulfurizing at 300°C of the copper thin film which was sealed in a glass tube with mg sulphur left on the tube wall in a vacuum of about 10-2 Pa. The energy dispersive spectrocscopy analysis indicated that they are the sulfides and the electron diffraction analysis indicated they have anti-fluorite structure.
