Ovary Structure and Oogenesis of Trypophloeus klimeschi (Coleoptera: Curculionidae: Scolytinae)

The female reproductive system, ovary structure and ultrastructure of Trypophloeus klimeschi (Coleoptera: Curculionidae: Scolytinae) were investigated using light microscopy, scanning electron microscopy, and transmission electron microscopy. Its female reproductive system is comprised of two ovaries (each ovary has two ovarioles), lateral oviducts, common oviduct, spermathecal sac, spermathecal pump, two accessory glands and bursa copulatrix. Well-developed endoplasmic reticulum can be clearly seen in the secretory cells of spermathecal sac. This species has telotrophic meroistic ovarioles that are comprised of terminal filament, tropharium, vitellarium and pedicel. The terminal filaments are simple; each is comprised of cellular peritoneal sheath. The presence of several clusters of nurse cells in the tropharium is indicative that its ovarioles conform to the transition stage. This indicates that there are at least two different types (transition stage and secondary stage) of ovarioles in Curculionidae.

Block Python as a transition stage in learning programming

Learning programming is an integral part of the school informatics course. The teachers often start to teach programming with the "childish" language Scratch, which, despite its simplicity, makes it possible to write not only the simplest program, but also quite complex programs that reflect the basic principles of programming such as variables, loops, branches, etc. Continuing learning programming pupils can use Python, which is one of the most popular programming languages. The article proposes an approach to implementing the continuity of programming learning in the transition from learning Scratch to learning Python, namely, using the capabilities of the online educational platform EduBlocks. EduBlocks is an easy way to go from block programming to text-based programming. The main part of EduBlocks is the visual block editor. After completing the construction of the program in this editor, you can go to the "regular" Python editor. Python code is displayed in blocks, so pupils learn Python syntax while coding in a familiar block-level environment.

The experience of adolescents being mothers at a young age scoping review

Life changes that occur in adolescents who marry at a young age provide challenges for adolescents in living a new life. The period of marriage, pregnancy and childbirth experienced by adolescents at a young age becomes a new transition stage for them to take on a new role to become a mother. The aim of the scoping review is to review evidence related to adolescent experiences of motherhood at a young age. This scoping review used the Arksey and O'Malley framework. Identification of relevant studies used 4 databases. The results of this scoping review consisted of 15 selected articles. The results of the thematic analysis emerged 2 themes, which were the psychological state of adolescents to become mothers at a young age and the support needed by adolescents when they become mothers at a young age.

Implementation of the Rational Unified Process (RUP) Model in Design Planning of Sales Order Management System

Sales order documents at retail companies are a very important procedure in the project or work initialization process. However, the management of the sales order which is still done manually creates several problems in the process. This research will try to offer a solution by building a sales order management system that is developed by applying the Rational Unified Process (RUP) method. 4 stages in the RUP must be carried out, namely: the initial stage, the elaboration stage, the construction stage, and the transition stage. To reduce the risk of changes desired by the user, testing is carried out at the end of each phase. The results of this study have succeeded in building an SO management system where each feature designed is successfully implemented, which is indicated by the results of measuring the functional suitability of the system at each stage getting a value of 1.

The liquid-liquid flow dynamics and droplet formation in a modified step T-junction Microchannel

The droplet generation mechanism in the step T-junction remains unknown, especially for the transition stage from dripping to jetting . In this work, the droplet generation mechanism was systematically investigated in a novel modified step T-junction. We found that under different fluid regimes, different factors take action. In dripping regime, the interfacial tension dominated the formation mechanism when the surfactant concentration was controlled below micelle concentration (CMC). In jetting regime, our experimental results showed that the influence of the surfactant concentration on the size of generated droplets was rather negligible while the phase ratio indeed determined such a parameter. In the dripping-jetting transition stage, an abnormal increase of droplet size was observed despite the increase of continuous phase flow. To the best for our knowledge, it is the first study to report generation mechanism in modified step T-junction from dripping to jetting regimes.

A MEASUREMENT TO ESTIMATE THE LEVEL OF DIGITAL TRANSFORMATION

A measure is proposed to estimate the degree of digital transformation of a social system that could be applied to different units of analysis: the organization, the industrial sector or society. The measure contemplates the existence of classic (non-digital) social systems, a transition stage and the transformation towards the digital social system. An estimate of the percentage of people who have made purchases over the Internet has been used to estimate the degree of digital transformation of different territories, regions and countries included in the INE and Eurostat statistics. The initially proposed function can serve as a basis to include panels of indicators or multiple parameters that diagnose other relevant aspects of society and the economy. In general, the measure could be useful to assess the transition and evolution of different types of systems.

Study on the Dynamic Performance of Locally Resonant Plates with Elastic Unit Cell Edges

A Floquet–Bloch approach is employed to demonstrate the stop bands for an infinite locally resonant plate. In addition, the effects of the connection stiffness of the unit cells on the band gap and dynamic performance of a locally resonant plate are analysed. The results show that the degree of inhibition of elastic waves in the band gaps increases rapidly when the connection stiffness of the unit cells increases within the scope of the transition stage stiffness. However, outside of the range of transition stage stiffness, the degree of inhibition of elastic waves in the band gaps basically remains unchanged. This discovery widens the application scope for vibration and noise control using locally resonant plates.

SOCIOCULTURAL TRADITION AND DIGITAL SOCIETY: TWO STRATEGIC LANDMARKS OF THE CHINESE FORESIGHT TECHNOLOGY

The article analyses the features of the formation and strategic guidelines of the Chinese foresight technology, its potential opportunities, the limits of its use in order to build the desired digital future and determine specific steps to achieve it effectively. To this end, the author considers the archetypal traces of the predictive activity of Ancient China, their interaction with modern predictive practice as an integral part of the design of the alleged digital image of the future. The paper determines theoretical and methodological foundations of modern Chinese foresight technology, initial basic methodological principles and technology of prospective step-by-step application of comprehensive foresight, including the method of scenario design. The article pays special attention to the understanding of modern China foresight projects, possibility of their implementation on the national basis and impact of foresight results on the Chinese model of development and change management at the transition stage to digital society.
