Show more

Hypospadias is a developmental abnormality in which the male urethra opens on the underside of the penis or on the perineum and can be accompanied by penile aplasia or hypoplasia, hypoplasia of the corpus cavernosum, incomplete formation of the prepuce, or cryptorchidism [1]. In animals, it rarely appears in horses, sheep, goats, cattle, dogs, and cats as isolated cases with urogenital anomaly or with other abnormalities [2,3]. The aim of this paper is to present the hystological results in a crossbred calf seen w...

Cemented paste backfill (CPB) is an engineering mixture of mine tailings, cement and water. Tailings can commonly contain sulphidic minerals. In this case, acid mine drainage (AMD) may occur due to the oxidation of sulphidic minerals present in the body of the CPB. In general, AMD lowers the pH of the medium and water environment and may cause heavy metal release. Therefore, AMD potential is an important parameter to be considered with regard to environmental aspect. Static tests are widely used to determine the A...

Our current IT innovations will alter the way government agencies operate. The relationship between public administration education and new forms of governance, such as e-government, is thus something to consider. Public administration education must be updated to reflect the structure of future governments. The paper discusses a number of key topics that are connected to the topic. Evolving aspects start to appear in public management in this century of information and information technology. Also, numerous books...

The use of natural products for healing purposes has gained great attention worldwide. Increased interest in certain plant products has been achieved mainly due to their ability to limit antibiotic resistance. Also, as the hypothesis that all biological processes at the cellular level are severely affected by the formation of free radicals has been confirmed, it is attempted to highlight some active principles in plants and their use as agents to counteract the oxidative process [1, 2]. This paper aims to demonstr...

Electrodeposition of composite coatings based on cobalt alloys from citratepyrophosphate electrolytes is investigated. The features of the co-reduction of cobalt with refractory metals (Mo, W, Zr) directly from the electrolyte solution are due to the mutual influence of thermodynamic and kinetic characteristics of alloy-forming components. Modern electrochemical technologies for surface treatment of titanium alloys to create protective, antifriction, dielectric, and catalytically active materials are considered. T...

Green development is a kind of development that considers two factors- social and environmental impacts of development. Information and Communication Technologies (ICTs) are tools that can be used in monitoring of the impacts of climate change. They can demonstrate the effects of climate change and they can contribute to the proper management of urban green via their role as decision-making tools. Urban areas have an important role in urban ecosystems through multifunctional role of trees, such as the reduction of...
