Abstract
A three dimensional (3D) medical image can provide a sense of reality for a doctor. A 3D printer can transform a 3D image into a 3D object, which provides communication between the doctor and his/her patients. One step to make the 3D object is to generate the g-code using a software. However, the existing software for creating the g-code still uses the user interface (a manual process). This study aims to generate g-code from Digital Imaging and Communications in Medicine (DICOM) format in Computerized Tomography (CT) through the cloud. The g-code generator is implemented using Phyton version 3 and runs on a computer using Linux (Ubuntu 18.4) as the operating system. The computer specification is intel core i9-9900K with motherboard Gigabyte Z390 Aorus Elite and graphic card Gigabyte GV-N208TGAMING OC11GC (memory 11GB). The medical image object is a bone that comprises craniofacial bone and thoracic vertebra, taken from multi-slice CT in DICOM format. The g-code file is suitable for a specific 3D printer. The performance criteria are the transferred data and visual shape comparison between the output from InVesalius 3.1 software and 3D printer (manually). The justification of the visual shape match from three radiology doctors for craniofacial bone and a thoracic vertebra is approximately 100% matching.

Abstract
Population control is very important for individual and national welfare. Although various synthetic contraceptive agents are available, their use is associated with severe side effects. Therefore, an approach is taken to identify new antifertility agents from natural sources. This study was conducted to determine the effect of areca nut extract on estradiol levels and the estrus cycle of female balb / c mice. The experimental animal models used were fifteen adult female balb / c mice, aged 8-12 weeks, weight 20-40 g and induced for 1 week with water extract of areca nut with a dose of 1 g / 200 g body weight of mice (K1), 2 g / 200 g of body weight of mice (K2) and distilled water in the control group (K0). The estrus cycle was identified by a daily assessment of the relative ratio of nucleated epithelial cells, cornified squamous epithelial cells and leukocytes found at the time of vaginal swabs for 15 days continuously. At the proestrus stage blood is taken from the tail. Serum estradiol levels were determined by ELISA technique. There was a decrease in serum estradiol levels in the treatment group 1 (K1) 1.9 times compared to the control group (K0) and decreased estradiol levels in the treatment group 2 (K2) 5.29 times compared to the control group (K0). Changes in the duration of the estrus cycle occurred in treatment group 1 (K1) to be elongated and treatment group 2 (K2) became non-estrus, while the control group (K0) did not change the duration of the estrus cycle (normal). The decrease in serum estradiol levels affects the estrus cycle of mice (P = 0,000). The administration of areca nut extract has the effect of reducing serum estradiol levels and disrupting the duration of the estrous cycle of female balb / c mice. This finding has important implications for the development of contraception in women.

Abstract
This article studies the electromagnetic properties of composite materials based on hexaferrite powders and a silicone binder. The results of this study are presented. Samples of radiomaterials based on hexaferrite powders Z-, W-, M-type and silicone binder were made. The measurements were carried out in a frequency range from 100 MHz to 18 GHz. The frequency dependencies of complex permittivity and permeability are shown. Based on the data obtained, the electromagnetic response for composites of various thicknesses located in free space and on the metal was calculated. The composite located on the metal, which contains 80 wt.% BaCo0.6Zn1.4Fe16O27 and has a thickness of 2 mm, can reduce the level of reflected radiation by more than 100 times in the frequency range from 12.5 to 18 GHz. A composite material containing 80 wt.% BaCo2.4Ti0.4Fe23.2O41 is effective narrowband absorber (reduces reflection by more than 100,000 times) at a frequency of 11.6 GHz, at a thickness of 2.6 mm.

Published: April 2020

AbstractThe paper proposes a solution of the issue of extracting textual information from a document image. There are many interesting solutions of this problem thanks to practical applications, such as text recognition, translation, forensics, etc. The quality of the text information of documents converted into images depends on the type of scene (simple or complex), type of digital camera (low-cost devices, mobile devices), the magnitude and direction of illumination, type of substrate (paper, plastic). These points lead to the fact that the automatic extraction of text from the image is extremely difficult.

Abstract
The paper presents the results of the development of a cloud system for multi-parameter aerodynamic calculations of unmanned aerial vehicles (UAVs). The developed cloud system consists of the following functional parts: web client – provides an access to the computing cloud, allows interactively preparing a task, sending prepared data to a computing cluster, getting and visualizing calculation results; and computing cloud – provides communication with the web client using an open API and manages the computing process. The computing process of the cloud is based on using open technologies of the OpenFOAM software adapted for solving aerodynamics problems. The authors carried out parametric studies of the external flow of UAV at free-stream velocities of 20, 25, 30 m/s with angles of attack from –4 to 12 degrees. It was found that the smallest drag force is observed for 0-3 degrees of the angle of attack of the flying wing, and the best lift to drag ratio is detected for 5 degrees attack angle. For 5 degrees attack angle the lift force is 47 N for an air free-stream velocity 20 m/s, 74 N – 25 m/s, 106 N – 30 m/s.
