Abstract
Polyhyroxyalkanotes (PHAs) are a family of polyhydroxyesters synthesized by numerous bacteria as an intracellular carbon and energy storage compound under nutrient-limiting conditions with excess carbon. An extensive screening program was previously done to isolate a promising bacterial isolate capable of polyhydroxyalkanoate (PHA) production. Polyhydroxalkanoates are biodegradable thermo polyesters like poly-β-hydroxybutyrate (PHB), which can be produced intracellularly as carbon and energy reserves. In this present study, out of 35 isolates, as many as 12 isolates were found to accumulate PHA which isolated from the oil and plastic contaminated soils, collected from different contaminated sites in Baghdad. However only one bacterial colony is selected among others based on maximum PHA yield (4.8g/L) after 48 hrs of incubation at 30°C with 54 % of PHA. Bacteria from this colony was characterized by morphological, biochemical and identified as Azotobater. The maximum PHA yield was recorded under the dry weight basis with 3% of corn oil wastes as the sole carbon source. However, Sudan black stained cells showed the presence of large quantities of granules in the cell cytoplasm when viewed under microscope. The polymer was extracted for the purpose of studying its physical and chemical properties.

Published: December 2019

Abstract
The article presents the dependence of the energy intensity of rock destruction on the inclination angle of blade of geokhod cutting body for the destruction of low hardness rocks. To formulate the research tasks, the main provisions of the geokhod technology for making workings are presented; the features of the new class of mining equipment, geokhod, are given. The research relevance is formulated. To determine the energy intensity of the rocks destruction, the method of calculating the power and geometric parameters of the geokhod blade cutting body was chosen. An algorithm has been developed for calculating the energy intensity of rock destruction, on the basis of which a computer program has been developed for determining the power parameters of the geokhod blade cutting body. In addition, the article presents well-founded forms of face, which appear as a result of destruction with the blade cutting body of the geokhod. To determine the influence of the inclination angle of the geokhod blade cutting body on the energy intensity of destruction, the geometrical parameters of the blade cutting body and the parameters of the mining and technical conditions of the mine working were justified. As a result of the study, it was revealed that the energy intensity of rock destruction with the blade cutting body decreases unevenly as the inclination angle of the blade towards the reverse cone increases.

Published: December 2019

Abstract
The task of controlling a positioning system drive with the active element of ferromagnetic shape memory alloy has been considered. The task is to provide the length increment of the active element by a given value from the resultant action – the pulse of magnetic field (or pulse series) with definite amplitude and duration. Methods of solving the task – the methods of tracking and scanning modes of the pulse reversal of the active element – have been suggested. To implement the method of scanning magnetization reversal, it is necessary to introduce a feedback link to reduce the positioning error due to the discrete nature of the effect and have information about the deformation of the element. A specific feature of tracking magnetic reversal is the use of experimental information to exclude overregulation. In testing process, an iterative process has been carried out to correct the mathematical model of deformation, using experimental data. To study the method, a software module has been developed in the LabVIEW graphical programming environment. The data obtained show that application of the method allows to increase the accuracy of controlling positioning systems based on ferromagnetic shape memory alloy.

Published: December 2019

Abstract
Wood as a structural material differs from other materials used in construction and industry, high variability of its properties. This is due, among other things, to the action of various variable factors – moisture content, temperature, inclination of fibers and others. The influence of wood moisture is especially strong – as a result of moistening the strength of wood considerably decreases in comparison with durability in absolutely dry condition. In addition, wood is a significantly nonlinear structural material. Non-linearity is manifested both in short-term and prolonged loading. Research of wood in time can be divided into two directions: longterm durability of wood and creep of wood. Modern models of wood creep are based on linear theories. Analysis of experimental data of various researchers on wood creep, has shown that the area of linear creep is observed at rather low levels of loading. At medium and high levels of experimental loading the existing models of linear wood creep theory do not correspond to experimental data. All this points to the actuality of the development of methods of calculating wooden structures for creep (linear and nonlinear), taking into account the wood moisture.

Published: December 2019

Abstract
In the integrated additive manufacturing of electronic products, the connecting bracket is a typical fixed structure for embedding electronic components such as PCBs, sensors, batteries, etc. The dimensional accuracy of column spacing affects the stability of embedded components directly. In this paper, aiming at the printing error of connecting bracket column spacing during the Fused Deposition Modeling (FDM), the printing error compensation is studied via the single factor experiments. The impact of design size on printing error is analyzed, and the printing error compensation model is established. Based on the FDM printing process of the connecting bracket, the main influencing factors of the printing error are analyzed. The results show that the column spacing printing error is the result of the combination of the dimension error of column printing, the dimension error of base printing and the motion error of the machine. Finally, based on the error compensation model, the compensated connection bracket is printed and the PCBs embedding verification is performed. The PCB can be embedded steadily, which indicates that the established model has higher precision.

Authors: Matarru Andre Amba , Syahid Muhammad , Yoesgiantoro Donny , Hadi Syahril 
Published: December 2019

Abstract
Stress Corrosion Cracking in Marine Applications, especially Ocean Current Turbines must be overcome. Al-10Si-5Mg Alloy which is based on the nature of flexibility and strength, is expected to survive from the SCC. The purpose of this paper is to examine the indications of SCC from immersed specimens in the 3.5% NaCl Solution + Aquades solution, then give varying deflections on the 3 Point Bending Testing. The other tests are harness testing, tensile testing, and macro visualization. The method is experimental for Al-10Si material in addition to a 5% Mg at casting. There are 9 specimens, namely 3 specimens from each of the 3 load values, namely 252 MPa (deflection (y)=2mm), 378 MPa (y=3mm), and 504 MPa (y=4mm). The results provide evidence that when the specimens were submerged with varying stresses, the absence of broken material was obtained even though there were indications of cracking and corrosion. Then the specimen that gets a high stress, becomes more susceptible to fracture due to the predominant cracking effect when compared to low standing specimens (σy=4 mm < σy=3 mm < σy=2 mm). So by the resistance to SCC, the Al-10Si-5Mg alloy can be recommended as an Ocean Current Turbine Blade material.
