This study sight to examine the use of as a cast preservative, the appearance of the concentration and soaking time of Acacia’s wood vinegar toward beam weight reduction due to termite counterattack. Nowadays in the market, many uses of fruit wood were used as an alternative effort to overcome deficiencies of wood supply or availability. Most of these fruit woods has a low durability grade. With a low level of durability, the wood will be susceptible to pests such as wood destroyer termites. One of the fruit woods is Durian wood which has II-III durable classes. To increase its service life, Durian wood must be preserved. Acacia’s wood vinegar can be practicaled as a cast preservative to prevent dry wood termite attack. The average value of absorption and retention are influenced by the duration of the concentration and soaking time of Acacia’s wood vinegar. The longer soaking time and the higher concentration of Acacia’s wood vinegar, absorption and retention values were also high. This value affects the percentage of the degree of damage and weight loss of Durian wood. The higher the retention and absorption, reduce the percentage of damage and loss of weight. The need for further research on Acacia wood vinegar so that it can be used as a natural preservative against termite attacks on strange wood speciesPenelitian ini bertujuan untuk melihat pendayagunaan cuka dari kayu Akasia selaku bahan pengawet yang alami dan pengaruh lamanya perendaman dan konsentrasi dari cuka kayu Akasia terhadap pengurangan berat dari kayu oleh rayap. Sekarang ini di pasaran banyak digunakan kayu buah yang dijadikan pengganti untuk mengurangi berkurangnya kesediaan bahan baku atau simpanan kayu. Kayu buah-buahan ini banyak yang memiliki tingkat awet yang rendah. Tingkatan keterawetan yang rendah sangat sensitif terserang hama seperti rayap perusak kayu. Satu diantara jenis kayu buah-buahan adalah kayu Durian yang berada pada berat jenis di rata rata 0,57 hingga tergolong di kelas kuat II-III, untuk meningkatkan masa pakainya maka kayu Durian harus diawetkan. Cuka pada kayu Akasia dapat dipakai untuk menghindari atau mengurangi serangan rayap kayu kering sebagai bahan pengawet alami. Nilai rata-rata absorbsi dan retensi kayu Durian dipengaruhi dengan lama perendaman kayu dan besarnya konsentrasi cuka kayu Akasia. Semakin lama waktu perendaman serta semakin tinggi konsentrasi cuka kayu Akasia maka nilai absorbsi dan retensi semakin tinggi. Nilai tersebut mempengaruhi besarnya persentase derajat kerusakan dan kehilangan berat kayu Durian. Semakin tinggi nilai absorbsi dan retensi maka persentase derajat kerusakan dan kehilangan berat cenderung menurun. Perlunya penelitian lebih lanjut mengenai cuka kayu Akasia sehingga dapat dimanfaatkan sebagai bahan pengawet alami terhadap serangan rayap pada jenis kayu lain

The production of grafted grapevine plant material is a complex process with many steps running over at least one year, from grafting to final sorting in nurseries. To reach the market in France, grafted grapevines must meet three criteria by law: resistance to a manual graft union test (or thumb test), a minimum number of three roots and a woody, lignified stem which has grown from the bud of the scion wood of at least 2 cm long. This study aimed to evaluate the possibility of using visual criteria to select good quality grafted grapevines, without the need to do the thumb test because the thumb test is manual and therefore very subjective; the test depends on the strength applied by the person who realises it. This study was done on 22 scion/rootstock combinations with different degrees of grafting success, i.e., producing different proportions of marketable plants after one year in the nursery. The three legal criteria currently used to select marketable grafted grapevines in France as well as other external and measurable criteria such as the length of lignified stem and diameter, the number of thin and thick roots, and rootstock wood diameter were measured on the 22 scion/rootstock combinations. Variation in the values for these different criteria was observed and correlations between the criteria and the number of marketable plants were studied. This data was then analysed to determine which visible criteria contribute most to identifying marketable grafts. The percentage of marketable grafts was most strongly correlated with the thumb test and positively correlated with the length of the lignified stem. The variables with the highest predictive effect for identifying marketable plants (other than the thumb test) were the number of large roots and the length of the lignified stem. The possibility of using visible criteria to screen for good quality grafted plants is discussed, but no single, or combination of criteria, was sufficiently strongly correlated with the percentage of marketable plants to replace the thumb test.

Né en 1925, mon père, Hans Albert Meyer, a eu deux nationalités : Dantzigois de naissance, puis naturalisé brésilien. En quatre périodes distinctes, il aura vécu près de la moitié de ses 85 ans en France. Son histoire doit autant à la violence du XXème siècle qu’à ses qualités propres. Par son père, il était issu d’une famille juive installée à Dantzig depuis des générations. Cette ville germanophone de la Ligue Hanséatique faisait partie de la Prusse. En 1919, le Traité de Versailles retira la ville à l’Allemagne pour en faire une cité-Etat - un statut qu’elle avait déjà connu dans son histoire - jusqu’à son invasion par Hitler le 1er septembre 1939, invasion qui marqua le début de la Seconde Guerre mondiale. Dantzig devint polonaise après la guerre, les chantiers navals de Gdansk jouant le rôle que l’on sait sur l’histoire de l’Europe, mais c’est là une autre histoire.

Сreation of indoor lighting systems with the possibility of changing its parameters in space and time is a promising direction within the framework of the intellectual environment system. The aim of this work was to create a methodology for calculating the illumination created by LED matrices which does not require the use of specialized software products and is adapted to the possibility of varying the parameters of LEDs and illuminated rooms.The urgency of creating a room lighting system that simulates the conditions of natural lighting taking into account the need to change its spectral composition in time, in space taking into account the physical and psychological state of a person is substantiated. The possibility of using well-known computer programs to calculate the distribution of illumination in the room is analyzed.A method has been developed for calculating the distribution of illumination on a plane using both a flat LED matrix and a matrix with an inclined arrangement of the planes of individual LEDs. It is shown that the distribution of illumination is a function of the indicatrix of the light intensity of the LED, its location in space, the number of LEDs in the matrix.Illumination distribution has been calculated for various light sources consisting of RGB LEDs both for desktop and ceiling lighting was calculated. It is established that when using matrices containing the same LEDs distribution of illumination is very nonuniform. The inclined arrangement of LED planes slightly increases uniformity reducing the maximum illumination. For ceiling lighting the option of uniform distribution of LEDs within the ceiling plane provides more uniform illumination than when the same number of LEDs are arranged in groups of matrices.Results of LED sources modeling indicate the need to modernize simple orthogonal matrices containing the same type of elements with the same power modes for all elements in order to increase the uniformity of illumination and efficiency. Such modernization can be carried out by changing the geometry of matrices differentiating the power modes of individual LEDs. The developed calculation program can be supplemented with options for introducing the above changes, as well as options for analyzing the spectral distribution of light in space.

Published: April 2022

The treatment planning process includes a review of the radiation treatment plan which leads to a decision on the patientʼs treatment technique. The scope of this study was to create a mathematical model for calculating of a radiation therapy session duration during the pre-radiation planning stage.For dosimetric planning of radiation treatment the authors provided a formula and an algorithm for determining of a patientʼs irradiation session duration. Radiation therapy session parameters such as radiation technique, number of monitor units, characteristics of radiotherapy equipment, number of radiation fields, radiation field parameters (angles of rotation of the radiotherapy coach, collimator, gantry), presence / absence of dose-modulating devices, dose rate, and duration of patient position verification procedures have all been taken into account during the development of software. The developed application explains how to define typical timing characteristics for various items as well as how to select a template from a built-in drop-down menu. If the dosimetric plan does not match for one of the templates, the program provides a space for defining of all parameters manually.The anticipated deviations of the true indicators from the expected indicators of the duration of the radiation therapy session were assessed. A total of 300 cases have been completely measured, with 100 cases studied for each irradiation technique (IMRT, VMAT, 3D). The maximum detection confidence value for the 3DCRT irradiation technique is 2.3 %, while the deviation for the IMRT and VMAT irradiation techniques is less than 1 %. The magnitude and degree of the deviation of the measured value from the expected one for a variety of characteristics and features have been revealed to depend on the actions of the personnel.The program developed allows medical physicists to analyze the timing parameters of the specified dosimetric planning methodologies directly on the treatment planning workstation. Evaluation of the duration of a radiation therapy session during the treatment planning stage, selection of various radiation treatment modalities, and consideration of the characteristics of the radiation session in each clinical case are available for analysis and further justified action.

Published: April 2022

In modern mechanical engineering, along with reducing the metal consumption of structures, the main task is to increase the reliability and durability of parts, assemblies of mechanisms. This problem never loses its relevance due to the ever-increasing requirements for manufacture of products, with the need to save scarce expensive metals and alloys and, as a result, replace them with economically more profitable options. One of the most promising, from the point of view of ecology, ways to replace metals, is to use in the construction of plastic assemblies, in particular polylactic acid (PLA). PLA is a biodegradable thermoplastic used in 3D-printing. The paper presents results of an experimental study on the rupture of samples obtained by 3D-printing from PLA under various technological operating modes of 3D-printer. The following parameters have been chosen as variable parameters: the form of filling samples (triangle, hexagon (honeycomb), line, edge), nozzle temperature (190–205 °С), sample filling factor (from 10 up to 40 %). Tensile testing of the samples have been carried out on a hydraulic tensile machine with a measuring software package in the Kason WDW-5 set. When performing tests, the conditional yield strength was considered the main out put indicator. The analysis of experimental data has shown a significant effect of the investigated technological parameters on the conventional yield point, which varied from 16.5 to 22.42 MPa. The most rational forms and sample filling factor, as well as the temperature of nozzle when printing with PLA, have been determined.

The present paper describes experiments and research outcomes concerning the construction of cement concrete pavements in South Kazakhstan, taking into account significant climate changes. The study has identified potential problems in the construction of cement concrete pavements in the region, where there was no experience of their construction until the mid-2000s. In order to develop an optimal solution, the technical factors that characterize the process of arranging these coatings using sliding molds are analyzed and quantitatively normalized. These factors include the optimal amount of mortar for curing concrete, the optimal joint cutting time, the interval and effective width of expansion joints to prevent the formation of cracks in concrete at an early age. The effectiveness of the use of polyethylene film to prevent the formation of contraction cracks and maintain the required mode of hardening of the cement concrete pavement is shown. The main cause of damage to the expansion joints along the length of the day coverage of coatings in the conditions of South Kazakhstan has been established. Recommendations have been developed for the installation of cement-concrete pavement and expansion joints during the construction of roads in this region. The accumulated data on climatic factors and methods of work with the use of polyethylene film have made it possible to create an optimal method for the construction of cement concrete pavements, which will improve the quality of roads in South Kazakhstan.

The paper considers options for reducing environmental losses in Polotsk and Novopolotsk through the development of trolleybus and tram systems – various types of urban electric transport. In order to reduce the costs of creating transport (including charging) infrastructure, as well as operating costs, the effectiveness of such systems has been determined when using not only classic types of transport, but also hybrid buses, electric buses, duo-buses. Approaches and methods have been developed to improve the quality of passenger service without deteriorating the environmental situation – this will become possible thanks to the development of tram and trolleybus traffic in Polotsk and Novopolotsk. Variants of scenarios for the use of various types of urban eclectic transport in the cities under study are presented, which will reduce investment in vehicles and the cost of creating an operational base at the expense of existing production facilities, for example, a tram fleet. In addition, this will make it possible to create and organize a unique agglomeration rail passenger system, which can become one of the ways to develop the tourist potential of Polotsk and Novopolotsk. The proposals outlined in the paper are aimed at improving the environmental situation in these cities by reducing the volume of emissions of harmful substances by buses, especially on the central streets.

To analyze the synchronization of machine-building production processes, a statistical approach is used on the correctness of the choice of parameters. The accuracy of the parameters is achieved by modeling. This method allows checking how correctly the parameters are selected and whether they ensure uninterrupted operation of production. Statistical analysis of parameters gives information on failures in a particular production unit, on violations of the synchronization of production processes, technological processes. With the help of statistical characteristics, it is possible to evaluate production as a whole. Statistical multidimensional analysis of complex production data allows to analyze the work of individual units, production blocks. The cluster analysis has been carried out by the method of K-medium production process with minimization of the total error probability. A geometric interpretation of the results of cluster analysis of production processes is given in the paper. The influence of factors on the work of production has been determined in the paper. The index factorial method with a different comparison base and different weights has been applied. The hypothesis about the adequacy of the model of production processes has been tested. A statistical analysis of the complex data of the production process has been carried out in the search for optimal solutions in the case of uncertainty and in conditions of risk using the following methods: Bayes, Laplace and Germeyer using the simplex method. The network methods of decision-making have been used in the paper. Statistical methods with the help of mathematical modeling have substantiated the optimal sizes of both individual parts and volumes of local warehouses, so that there were no delays in the transfer of production processes, disruptions in work, downtime of working equipment. In this case, the criterion for the optimality of production volumes can be the minimum of total losses from idle time of individual units and production blocks to the possibility of disruption of the synchronous process modes due to lack of equipment (arising production pockets) or due to long-used outdated units.
