The article considers the restoration of the connecting rod, one of the basic and most numerous parts of the connecting rod – piston group. (Research purpose) The research purpose is in analyzing the possibilities of various technologies for the restoration of "chipped" connecting rods and giving technological proposals for their restoration for the company "Motortechnology". (Materials and methods) The research object is the "chipped" connecting rod of the Cummins engine as one of the most massive engines used on KAMAZ vehicles. It was proposed to use electric spark processing technology to restore the lower head of the "chipped" connecting rod. It is possible to obtain a new layer with predictable characteristics depending on the parameters of the spark discharge, the composition of the electrode material, the material of the work piece and other factors. The resulting coating will have properties different from the base material, which can be controlled within a wide range and provide the required qualities, such as increased microhardness, wear resistance, heat resistance. The important advantage of the electric spark processing technology is the absence of a significant thermal effect on the part during processing, therefore, thermal residual deformation of the part is excluded. (Results and discussion) The article presents the data on the effectiveness of the restoration of "chipped" connecting rods with the use of electric spark technology as an independent technological process, and when using various combined coatings. (Conclusions) To improve the physical and mechanical properties of the coating when restoring "chipped" connecting rods with a wear of more than 100 micrometers, it is advisable to restore them in a combined way, where the first layer is an electric spark coating, the second layer can be gas dynamics, metal polymers or an electrochemical coating method.

Published: February 2022

The application of various types of functional and protective coatings made of inorganic materials to parts made of conventional structural materials will be able to solve the issue of ensuring the planned service life of modern devices, machines and mechanisms. Electric arc metallization, characterized by relatively high productivity and low cost of coating, serves as one of the methods of applying gas-thermal coatings. However, the high porosity of the resulting coatings, their low adhesion strength to the substrate and plastic properties prevent the widespread use of this method. (Research purpose) The research purpose is in studying the chemical, thermal and mechanical effects on samples obtained by electric arc metallization, on the adhesive, cohesive and strength properties of the coating and the areas of connection of the coating with the substrate. (Materials and methods) The authors used electric arc metallization and gas-dynamic spraying to obtain the necessary coatings. A mechanical effect on the coating was studied using the machine IZH- 250TV and special research equipment to determine the properties of coatings and substrates. (Results and discussion) Gas-thermal coatings can be successfully used in the manufacture of new and restoration of worn parts of agricultural machinery. The processing of metallized samples by surface plastic deformation are expedient and necessary. Chemical and thermal treatment has a positive effect on the properties of the coating and the substrate, increasing the value of microhardness by 50-70 percent. The use of supersonic metallization devices leads to an increase in adhesive strength by 30-35 percent. (Conclusions) The study showed that chemical and thermal treatment has a positive effect on the properties of the coating. Plastic deformation of the sprayed surfaces is practically equivalent to thermodynamic effect. It is recommended to use plastic deformation for spraying cylindrical surfaces.

Authors: Fedotova G. Yu.
Published: February 2022

The article presents the results of a study of the problems of using the Harmonized System (HS) for Description and Coding of Goods as the main element of the Commodity Nomenclature of Foreign Economic Activity (CN FEA) of the EAEU. Given the global nature of the nomenclature, the author focuses on the practical features of using the system in international trade and customs purposes. Based on the analysis of literary sources, the author highlighted the main problems of using the HS and CN FEA of the EAEU. In the work, quantitative and qualitative research methods were used: a comparative semantic analysis of the use of a product name allowed the author to identify difficulties in application and incomplete compliance with the requirements of international trade. An empirical study of the classification characteristics of goods showed illustrative examples characterizing the presence of outdated and inappropriate terms and concepts that do not correspond to modern practice, which limits the use of the texts of the items of the nomenclature. The investigated compliance of the classification characteristics of goods used in the HS and CN FEA of the EAEU showed a lack of uniformity between the identification criteria and marking information in technical regulations, in terms of use for the purposes of compliance with prohibitions and restrictions. The structural analysis of the HS and CN FEA of the EAEU showed examples of the lack of structural uniformity in the assignment of goods made of the same material.The study of the possibility of using the HS and CN FEA of the EAEU for search queries showed restrictions on their use for automatically determining the product code. Based on the totality of the study, the author has shown the discrepancy between the HS and CN FEA of the EAEU with the modern requirements of international trade in terms of the application of concepts, classification signs, systematization and the growing need for a radical revision of the HS.

Setiap beberapa waktu perawat melakukan pemantauan tetes cairan infus dengan manual secara langsung. Bahkan, saat cairan infus akan habis, keluarga pasien harus memanggil perawat untuk melakukan penggantian cairan infus. Hal ini bisa menyebabkan terlambatnya penanganan terhadap pasien karena keterbatasan waktu. Oleh sebab itu, dibutuhkan sebuah alat pemantauan tetes cairan infus yang dapat memberikan notifikasi otomatis bahwa cairan infus akan habis. Artikel ini menjelaskan tentang implementasi alat pemantauan tetes cairan infus berbasis IoT yang terhubung dengan perangkat android. Prototipe ini menggunakan sensor Optocoupler sebagai pendeteksi adanya tetes cairan infus, Motor Servo SG90 untuk menekuk selang infus, Mikrokontroler ESP32 sebagai pengendali. Komunikasi perangkat keras dengan perangkat android menggunakan server lokal sehingga harus menggunakan Hotspot WiFi yang sama. Data yang dikirimkan dari perangkat android akan tersimpan ke database kemudian diakses oleh ESP32 sehingga menjalankan sensor dan motor servo. Pada android application terdapat informasi kondisi tetes cairan infus yang sudah dikonversi menjadi persentase sisa cairan infus. Hasil eksperimen menunjukkan bahwa prototipe dapat melakukan pengaturan tetes cairan infus per menit sesuai dengan yang diinginkan dan android application dapat menampilkan status dan mengirimkan notifikasi secara akurat. Sebagai kesimpulan dari hasil pengukuran, rata – rata rasio persentase yang dicapai dalam pengujian mencapai 70 % dengan rata – rata error sebesar 1,46 %.

Automated Guided Vehicle (AGV) merupakan sebuah alat yang berfungsi untuk mendistribusikan barang dari suatu tempat ke tempat lain. Penghubung antar station menggunakan jalur garis berwarna hitam. Robot AGV terdiri atas sensor infra merah sebagai umpan balik PID, mikrokontroler sebagai pengolah data serta menjalankan alogaritma PID dan motor DC sebagai aktuator. Robot ini bisa diaktifkan menggunakan smartphone yang memanfaatkan sinyal bluetooth. Untuk dapat membuat AGV bergerak stabil, dengan cara penerapan kontrol PID salah satunnya dengan mengimplementasikan metode Ziegler Nichols pada pencarian parameter PID robot AGV. Proses tuning diawali dengan pemberian parameter Kp = 0, kemudian ditingkatkan secara bertahap hinga didapat grafik respon PID yang berkesinambungan. Dari grafik respon yang diberikan, dapat menentukan besar nilai critical gain Kcr dan critical periode Pcr. Nilai Kcr dan Pcr digunakan untuk mendapatkan nilai parameter Kp, Ki dan Kd sesuai dengan aturan yang terdapat dalam metode Ziegler Nhicols. Hasil pengujian tuning parameter PID menggunakan metode Ziegler-Nichols didapatkan nilai Kp= 7, Ki=1,5 dan Kd= 1. Dengan menggunakan parameter tersebut respon robot menjadi lebih baik dan mendekati set point.

Forest vegetation management plays an important role in maintaining soil
health and function. In highly-managed urban forests, the clearing of
understory vegetation has potential to cause loss of soil nutrients,
resulting in stoichiometric imbalances and a decrease in soil function.
Therefore, studying how to effectively manage understory to improve soil
quality is critical for stability and function of urban forest. Here, we
collected soil samples from a plantation forest in Zijin Shan National
Forest Park in two stands, each with three adjacent plots with different
understory management practices: one with high diversity natural
understory vegetation, another with low diversity managed understories
of ornamental groundcover (Reineckia carnea (Andr.) Kunth or Ophiopogon
bodinieri Levl.), and a third with cleared understory. Compared to plots
with natural understories, we found lower levels of soil total carbon
(C), total nitrogen (N), and some their fractions especially microbial C
and N, in plots with no understories. Correspondingly, ratios of soil C:
phosphorus (P) and N:P, and microbial C:N, were lower in the absence of
understories in one of the two stands. These influences were smaller
with ground-cover plants in both stands, particularly O. bodinieri. The
magnitude of these effects differed between the two stands, with greater
effects observed in the stand with higher soil C. While we cannot rule
out the effects of other influences on soil properties, these results
offer support for the hypothesis that human management practices affect
urban forest soil properties and microorganisms, and that appropriate
understory managements can alleviate these adverse influences.

Introduction: Vascular endothelial growth factor (VEGF)is an angiogenic
marker and implicated in carcinogenesis and prognostication of cancers.
However its prognostic potential in a rare cancer-Ewing’s sarcoma merits
exploration. Methods: Histopathologically confirmed consecutive ES cases
registered at our institute from 2014 to 2018 were analysed.
Immunohistochemical staining for VEGF was performed on tumour tissues
and they were further classified based on VEGF intensity. Results: There
were 105 patients including 53 non-metastatic and 52 metastatic. VEGF
immunostaining in non-metastatic and metastatic cohort was negative in
20 (37.7%) and 21 (40.4%), mildly positive in 13 (24.5%) and 9
(17.3%) cases, moderately positive in 14 (26.4%) and 16 (30.8%), and
was intensely positive in 6 (11.3%) and 7 (13.5%) patients,
respectively. VEGF immunoexpression up to 25% was seen in 14 (13.3%)
and 10 (9.5%) patients within the non-metastatic and metastatic cohort,
respectively. The median EFS and OS for the entire cohort were 26.4
(95% CI 17.6-NA) and 32.5 (21.3-NA) months, respectively. Metaststatic
ES patients having either VEGF immunostaining in >25%
tumor cells or moderate /strong immunostaining were found to inferior
EFS and OS [p= 0.017, HR-0.153; p=0.013, HR-0.109
respectively].Additionally, treatment-naïve, compliant and
non-metastatic patients had superior EFS (p=0.000, 0.000, 0.020, 0.022
respectively) and OS (p=0.000, 0.000, 0.006, 0.041 respectively).
Conclusion: VEGF expression and intensity were found as independent
negative prognostic marker in Ewing sarcoma .This may translate to
therapeutic relevance but needs validation in the subsequent, larger
prospective studies.

Knowledge - Discovery or Revelation?

The term "knowledge" is difficult to understand when we want to define it. This is why "knowledge" has been reconstructed as a cluster concept that points out relevant features but that is not adequately captured by any definition. As long as knowledge can only be situated in forms of time, it is doomed to remain truncated and to manifest disjointly. Knowledge's lack of unity is expressed into different forms of knowledge. Fragmented by the cutouts that allowed its manifestation, knowledge is - whatever type of knowledge we talk about - incomplete, subjective, limited, and fragmentary and, in most cases, it is not possible to understand exhaustively a specific domain. That is why, in this paper, we pursue a transdisciplinary exercise, involving science and religion, and an interdisciplinary one, involving disciplines and theories found in the complex systems theory.
