Abstract

Introduction
Retrograde ejaculation (RE) consists of the reflux backwards, towards the bladder, of the ejaculate, during the emission phase of ejaculation, causing a total or partial absence of sperm emission, with the consequent diversion of semen into the bladder during the emission phase of ejaculation. Evaluating the ejaculate may not be sufficient for identifying RE in some patients. Hence, the management of infertility may involve the use of invasive methods such as epididymal fluid retrieval or testicular biopsy.

Content
This paper defines RE and methods for its diagnosis. A description is also provided of the techniques used for the detection of sperm in post-ejaculatory urine (PEU), the preparation and retrieval of sperm from urine and their subsequent use in assisted reproductive techniques.

Summary
The diagnosis of RE is based on the detection of spermatozoa in PEU in patients with aspermia or oligozoospermia and low or normal seminal volume. Although the presence of sperm in PEU could be sufficient for a diagnosis of RE, there is a lack of consensus regarding the diagnostic criteria for PEU, and the literature available is very limited. A correct diagnosis of RE allows the use of PEU for recovering sperm and its subsequent use in assisted human reproduction techniques, thus avoiding invasive techniques.

Outlook
A significant number of patients with RE may remain undiagnosed. Therefore, it is essential to conduct an RE study in patients with suspicion, through the analysis of PEU, and to properly interpret the results for accurate diagnosis.
Utilizing nano-computed tomography to characterize the structural nature of industrial minerals

Abstract
X-ray computed tomography (XRT) is a nondestructive and thus reproducible examination method allowing the three-dimensional (3D) investigation of the internal and external structures of objects regardless of their material and geometry. In the present study, XRT was used to investigate the influence of hydrochloric acid leaching on the composition and constitution of iron-rich bauxite grains.
Reducing the iron content in raw bauxites by acid leaching is a promising method for the beneficiation of iron-rich bauxites for subsequent use in the refractory industry. Not only the effect of the leaching process on the chemical composition of the bauxites, but also aspects such as the acid’s influence on the mineralogical composition and the resulting porosity of the individual grains have hardly been taken into account so far. To address these issues, various bauxites were examined before and after acid leaching using XRT analysis and specifically characterized with regard to their constitution.

Zusammenfassung
Der Beitrag knüpft an die aktuelle Debatte um die Transformation moralischer Werte in und durch Organisationen an. Jüngere neoinstitutionalistische Arbeiten modellieren mittlerweile zwar das erwartbare Auseinanderklaffen von Behauptungen und Praxis nuancierter als ältere, werfen allerdings kein konzeptionelles Schlaglicht auf die Interaktionen innerhalb normativ formatierter Organisationsstrukturen. Unsere kommunikationstheoretische Modellerweiterung lenkt den Blick auf genau diese intersubjektiven Aushandlungsprozesse. Sie basiert auf den Ergebnissen einer ethnografischen Studie zu hochselektiven Auswahlverfahren für „talentierte“ Führungskräfte von Konzernen, die neben der klassischen Leistungsbewertung explizit auch normativ aufgeladenen Konzepten wie Diversity und Chancengleichheit Rechnung tragen wollen. Wir gelangen zum Schluss, dass sich die Prozessierung solch konfligierender Werte als Übersetzungskaskaden beschreiben lässt. Diese verdichten wir konzeptionell in der analytischen Unterscheidung zwischen formalen und situativen Übersetzungen von Moral.
FEM Analysis on Isotropic Consolidation of Unsaturated Soils Using Ceramic Disks and Microporous Membrane Filters for Suction Control

Abstract
Microporous membrane (MM) filters with a significantly thin thickness have recently been used as an alternative to ceramic disks for matric suction control in the axis-translation technique for element tests on unsaturated soils. Although researchers have highlighted some discrepancies in test results when ceramic disks and MM filters are used, the mechanism leading to these discrepancies has not yet been clarified. In this study, suction-controlled triaxial tests were first conducted on unsaturated completely decomposed granite using two filters. Then, it is natural to believe that the different thicknesses of ceramic disk and MM filters may significantly influence the suction equilibrium process of specimens. To clarify this issue, soil-water-air coupled finite element modeling was performed to simulate the consolidation process in triaxial tests as an initial/boundary value problem. In the numerical calculation, the influence of the void ratio on the water retention curve (WRC) of soil was properly considered by adopting a deformation-dependent WRC model. In particular, the ceramic disk and MM filter, along with the specimens, were modeled, and their differences in thickness were considered. The calculated results show that a nonuniform distribution of suction occurred in the ceramic disk, leading to greater drainage discharge of the specimens. In other words, the influence of the thickness difference between the MM filter and ceramic disk cannot be neglected. However, regardless of whether ceramic discs or MM filters are used, the uneven distribution of the state variables in the specimens may occur in the triaxial tests for unsaturated soils, which emphasizes the importance of assessing the soil tests using the present axis-translation technique as initial/boundary value problems.

This research used mixed method by combining quantitative and qualitative methods under concurrent embedded design. The population of this research consisted of all students in the mathematics department of one of universities in Central Java. The sample was groups of students in the Study Program of Mathematics and Mathematics Education who enrolled in Integral Calculus course. From these two study programs, two sample groups (experiment group and control group) were selected randomly. An experiment group was taught by using web-assisted brain-based learning, while the other group (control group) was taught by using conventional learning. From this research, it can be concluded that the enhancement of the studentsâ€™ mathematical reasoning who were taught by using web-assisted brain-based learning are better than the achievement and enhancement of those who were taught by using conventional learning.
