Design Recommendations for Web-based Career Guidance Platforms - Let Young Women Experience IT Careers!

Despite a variety of intervention programs in the western society over the last decades, still too few young women are interested in an information technology (IT) career. While looking for career information and guidance, young women consult family and friends but also the internet. Although there is already a plethora of career information websites, those are seldom tailored to the interests of young women. To address the IT-gender gap with the design of a platform that appeals to the needs of the target group, we firstly analyzed existing German websites for career information and guidance. The analysis was framed by literature on women’s IT career choice barriers. Secondly, we evaluated selected websites with focus groups of female students. Finally, we present design recommendations to enhance web-based career information and guidance platforms for young women to raise their interest in IT-related careers

Verification of Conjugate Heat Transfer Models in a Closed Volume with Radiative Heat Source

The results of verification of mathematical model of convective-conductive heat transfer in a closed volume with a thermally conductive enclosing structures are presented. Experiments were carried out to determine the temperature of floor premises in the working conditions of radiant heating systems. Comparison of mathematical modelling of temperature fields and experiments showed their good agreement. It is concluded that the mathematical model of conjugate heat transfers in the air cavity with a heat-conducting and heat-retaining walls correspond to the real process of formation of temperature fields in premises with gas infrared heaters system

Multi-color Cavity Metrology

Long baseline laser interferometers used for gravitational wave detection have proven to be very complicated to control. In order to have sufficient sensitivity to astrophysical gravitational waves, a set of multiple coupled optical cavities comprising the interferometer must be brought into resonance with the laser field. A set of multi-input, multi-output servos then lock these cavities into place via feedback control. This procedure, known as lock acquisition, has proven to be a vexing problem and has reduced greatly the reliability and duty factor of the past generation of laser interferometers. In this article, we describe a technique for bringing the interferometer from an uncontrolled state into resonance by using harmonically related external fields to provide a deterministic hierarchical control. This technique reduces the effect of the external seismic disturbances by four orders of magnitude and promises to greatly enhance the stability and reliability of the current generation of gravitational wave detector. The possibility for using multi-color techniques to overcome current quantum and thermal noise limits is also discussed

РАЗВИТИЕ ФОНДОВОГО РЫНКА КАК ФАКТОР АКТИВИЗАЦИИ ИННОВАЦИОННОГО ФИНАНСИРОВАНИЯ ПРЕДПРИЯТИЙ В УКРАИНЕ

Становления фондового рынка в Украине является чрезвычайно актуальным, ведь именно от него зависит дальнейшее продвижение и укрепление экономики, расширение возможностей финансирования инновационной деятельности отечественных предприятий на микро-и макроуровне. Поэтому целью данной статьи является исследование с помощью абстрактно-логических и математических методов анализа общих тенденций развития и противоречий фондового рынка в Украине, путей их преодоления; возможностей расширения финансирования инновационной деятельности отечественных предприятий на основе развития и трансформации фондового рынка.Проблема активизации инновационной деятельности предприятий является достаточно актуальной на современном этапе развития Украины. Трудности в инновационной сфере связаны с внутренними проблемами государства в научно-технической, экономической, политической, социальной сферах. Но одной из важнейших проблем, стоящих перед любой компанией, является проблема привлечения ресурсов для финансирования новых или поддержания уже имеющихся у нее инвестиционных проектов

Oxidative functionalization mechanisms in organic synthesis using fenton reaction systems

We argued an oxywater-oxene concept for hydrogen peroxide transformation in Fenton reaction systems and used this interpretation for mechanisms explanation of hydroperoxide monooxygen oxidative functionalization processes (alkane and arene hydroxylation, alkene epoxidation, Baeyer-Villiger ketone oxidation to ester, organonitrogen compounds N-oxidation and organosulfur compounds S-oxidation) and dioxygen alkene and alkadiene functionalization processes (synthesis of hydroperoxides and cyclic peroxides)
