Facing any testicular lesion one must practice a total orchiectomy. Or this principle has been the standard dogma for a long time, it is no longer today. However, the advancement of diagnostic and therapeutic means has highlighted conservative surgery over ablative surgery. In this paper, we report 2 clinical cases of 2 young men with testicular lesions in different contexts, and exposing our arguments and the difficulties faced during the course of care. We also share our results and also those reported in the literature.

Level Of Motivation

The problem of social success has not been considered as an independent one in Psychology for a long time, but it has been included in the structure of research related to effective communication, social status and professional competence. The increased interest in it is due to the growing attention to the problem of personality changes, an increase in the environmental “challenges” to human abilities, as well as the need to quickly respond to changes in society. The authors study the role of social success in the structure of mental development of the personality; define the determinants that affect its formation and development. The purpose of research is to study the correlation between the level of motivation for success and assumptions on social success among youthful age. The study involved 258 respondents (99 young men and 159 young ladies aged 18 to 21 years). The researchers used a psychodiagnostic method, including two techniques (the “Successful person” method by G.R. Khuzeeva, the method of diagnosing motivation for success by T. Ehlers, in adaptation of E.P. Belinskaya), methods of mathematical and statistical analysis, a genetic method. The results of the study showed that the assumptions on social success in youthful age is associated with getting education, self-confidence, determination, hard work. The authors revealed the relationship between the learners’ level of motivation for success and their assumptions on social success. In a group of young men with a high level of motivation for success, assumptions on social success are associated with the activity aspect (diligence, one’s own activity, responsibility) and the humanistic orientation (well-disposed, responsive, able to sacrifice). Respondents with a low level of motivation for success have a material orientation in the image of success (careerist, entrepreneurial, has connections with the right people).

Clinical Cases

The endothelium keratoplasty of various modifications (DSEKTDMEK) is the first operation of choice under endothelium pathology of cornea of different genesis. The endothelium transplantation is most often implemented against the background of pseudophakia or at the same time instant with extraction of cataract and implantation of artificial crystalline lens. The clinical cases of damage of transparency of artificial crystalline lens after a routine extraction of cataract are known for a long time while dimness after endothelium transplantation is a new occurrence and related publications are singular. The study was carried out to present cases of damage of transparency of artificial crystalline lens after endothelium transplantation. During 2006-2015 more than 500 patients underwent endothelium transplantations in modifications of DLEK, DS(A)EK, FS-DSEK, invFS-DSEK and DMEK. The most of them (n=291) continue to be under regular or periodic observation. During average period of observation (78±16.8 months) four cases of dimness of artificial crystalline lens after endothelium keratoplasty were established. The biomicroscopy, visiometry and photoregistration were the main analysis techniques of establishing and studying of dynamics of dimness of crystalline lens. It is extremely difficult to establish the nature of dimness of intraocular lens after endothelium keratoplasty because explantation of intraocular lens is required. The surgical inflammatory reaction and presence of air in front camera are common for all cases of dimness of intraocular lens. The damage of transparency of intraocular lens is a complication of remote period after endothelium transplantation. The application of original technique of pneumocorneopexia promotes significant reduction of recurrent injections of air and possibly decreasing of probability of damage of transparency of intraocular lens.

Up to this writing, the late John Dewey remains by all odds our most influential American philosopher of education, and it is a long time since any other individual of any nation has had so much influence on educational theory and practice at home and abroad. He is also one of our most influential philosophers in general, and this in spite of the fact that young men are not now espousing his philosophy. An obvious fact about him is that he is characteristically American: he is a meliorist and reformer, an experimentalist, energetic and resourceful, and, as it were, a born pioneer and frontiersman. He is impatient, always in a hurry, wanting to get a lot of things done, sure that to change things is to better them, and committed to change as integral to being if not its very core. “To be,” he said, “is to be in process, in change.” In all these matters central to Dewey, his thought is remarkably conventional. We are like Dewey in many of these things, or Dewey is like us.

In recent years, the electron microscope has been significantly improved in resolution and we can obtain routinely atomic-level high resolution images without any special skill. With this improvement, the structure analysis of organic materials has become one of the interesting targets in the biological and polymer crystal fields.Up to now, X-ray structure analysis has been mainly used for such materials. With this method, however, great effort and a long time are required for specimen preparation because of the need for larger crystals. This method can analyze average crystal structure but is insufficient for interpreting it on the atomic or molecular level. The electron microscopic method for organic materials has not only the advantage of specimen preparation but also the capability of providing various information from extremely small specimen regions, using strong interactions between electrons and the substance. On the other hand, however, this strong interaction has a big disadvantage in high radiation damage.

For a long time, the development of dynamical theory for HEER has been stagnated for several reasons. Although the Bloch wave method is powerful for the understanding of physical insights of electron diffraction, particularly electron transmission diffraction, it is not readily available for the simulation of various surface imperfection in electron reflection diffraction since it is basically a method for bulk materials and perfect surface. When the multislice method due to Cowley & Moodie is used for electron reflection, the “edge effects” stand firmly in the way of reaching a stationary solution for HEER. The multislice method due to Maksym & Beeby is valid only for an 2-D periodic surface.Now, a method for solving stationary solution of HEER for an arbitrary surface is available, which is called the Edge Patching method in Multislice-Only mode (the EPMO method). The analytical basis for this method can be attributed to two important characters of HEER: 1) 2-D dependence of the wave fields and 2) the Picard iteractionlike character of multislice calculation due to Cowley and Moodie in the Bragg case.

The electron holes confined to the CuO2-plane are the charge carriers in high-temperature superconductors, and thus, the distribution of charge plays a key role in determining their superconducting properties. While it has been known for a long time that in principle, electron diffraction at low angles is very sensitive to charge transfer, we, for the first time, show that under a proper TEM imaging condition, it is possible to directly image charge in crystals with a large unit cell. We apply this new way of studying charge distribution to the technologically important Bi2Sr2Ca1Cu2O8+δ superconductors.Charged particles interact with the electrostatic potential, and thus, for small scattering angles, the incident particle sees a nuclei that is screened by the electron cloud. Hence, the scattering amplitude mainly is determined by the net charge of the ion. Comparing with the high Z neutral Bi atom, we note that the scattering amplitude of the hole or an electron is larger at small scattering angles. This is in stark contrast to the displacements which contribute negligibly to the electron diffraction pattern at small angles because of the short g-vectors.

Intermetallic Matrix Composites

Intermetallic matrix composites are candidates for ultrahigh temperature service when light weight and high temperature strength and stiffness are required. Recent efforts to produce intermetallic matrix composites have focused on the titanium aluminide (TiAl) system with various ceramic reinforcements. In order to optimize the composition and processing of these composites it is necessary to evaluate the range of structures that can be produced in these materials and to identify the characteristics of the optimum structures. Normally, TiAl materials are difficult to process and, thus, examination of a suitable range of structures would not be feasible. However, plasma processing offers a novel method for producing composites from difficult to process component materials. By melting one or more of the component materials in a plasma and controlling deposition onto a cooled substrate, a range of structures can be produced and the method is highly suited to examining experimental composite systems. Moreover, because plasma processing involves rapid melting and very rapid cooling can be induced in the deposited composite, it is expected that processing method can avoid some of the problems, such as interfacial degradation, that are associated with the relatively long time, high temperature exposures that are induced by conventional processing methods.

Specimen support and astigmatism correction in Electron Microscopy are at least two areas in which lacey polymer films find extensive applications. Although their preparation has been studied for a very long time, present techniques still suffer from incomplete release of the film from its substrate and presence of a large number of pseudo holes in the film. Our method ensures complete removal of the entire lacey film from the substrate and fewer pseudo holes by pre-treating the substrate with Gum Arabic, which acts as a film release agent.The method is based on the classical condensation technique for preparing lacey films which is essentially deposition of minute water or ice droplets on the substrate and laying the polymer film over it, so that micro holes are formed corresponding to the droplets. A microscope glass slide (the substrate) is immersed in 2.0% (w/v) aq. CTAB (cetyl trimethyl ammonium bromide)-0.22% (w/v) aq.
