Effect of microsurgical subinguinal varicocele repair on chronic dull scrotal pain in men with grade II-III lesions

Introduction: We aimed to evaluate the effectiveness of microsurgical subinguinal varicocele repair in patients with grade II-III lesions and chronic dull scrotal pain. Materials and Methods: A total of 29 patients with grade II-III varicocele and chronic dull scrotal pain that had a microsurgical subinguinal varicocele repair were included in the study. They were followed-up for 6-12 months inclu

A transition perspective on alternatives to coal in Chinese district heating

China uses half the world’s annual coal consumption, since coal is the primary energy source for heating in urban areas, particularly in northern China. This entails significant challenges for urban air quality in China and for the global climate. Unlike the electricity and transportation sectors, the heating sector has received little attention from policy and research actors in China, despite ve

Modularization of skill ontologies for industrial robots

With industrial robots ready to take the next step in mastering manufacturing tasks new approaches to reduce the programming effort are needed. This is achieved by introducing skills as robot "know-how" and using them as a higher abstraction level of robot instructions during programming. The skills are reusable items providing motion control and rich declarative descriptions of complex robot capa

Mass and UV-visible spectral fingerprints of dissolved organic matter : Sources and reactivity

Advanced analytical techniques have revealed a high degree of complexity in the chemical makeup of dissolved organic matter (DOM). This has opened the door for a deeper understanding of the role of DOM in the aquatic environment. However, the expense, analytical cost, and challenges related to interpretation of the large datasets generated by these methods limit their widespread application. Optic

Characteristics of heat transfer around an obstacle controlled by the presence of ribs

Using liquid crystal thermography, experimental studies were carried out to investigate the local heat transfer of an obstacle integrated with a rib. The rib was positioned in the upstream region of the obstacle to disturb the boundary layer of the approaching flow by precipitating the flow separation and reatt achment. The spacing between the rib and the obstacle is of primary importance. The spa

Individual consistency of long-distance migration in a songbird: significant repeatability of autumn route, stopovers and wintering sites but not in timing of migration

Through new tracking techniques, data on timing and routes of migration in long-distance migrant birds are accumulating. However, studies of the consistency of migration of the same individuals between years are still rare in small-sized passerine birds. This type of information is important to understand decisions and migration abilities at the individual level, but also for life history theory,

Fifteen years of quantitative trait loci studies in fish: challenges and future directions

Understanding the genetic basis of phenotypic variation is a major challenge in biology. Here, we systematically evaluate 146 quantitative trait loci (QTL) studies on teleost fish over the last 15 years to investigate (i) temporal trends and (ii) factors affecting QTL detection and fine-mapping. The number of fish QTL studies per year increased over the review period and identified a cumulative nu
