Spectral line shape and angular momentum
Authors: Barton D , Williams JF , Samarin S 
Published: August 2019

Abstract
Data have been obtained for ejection of valence shell 4p and 3d electrons in krypton and the 1t2 and 2a1 orbitals in methane. Measurements, with kinematics both on and off the Bethe ridge, examine how the spectral shapes change for fixed energies of 1015 eV for the incident electron, 880 eV for scattered and 120 eV for ejected electron and angular momentum changes. The studied interactions are activated by excitation and ionization of inner shell (-d) electrons and concern complex electron correlations. The triple differential cross sections for the Bethe ridge conditions within the experimental accuracy are similar to the values predicted by the Distorted Wave Impulse Approximation and Born Approximation calculations but need further consideration of electron correlation effects.

Ab-initio studies of few photon ionisation of helium
Authors: Katravulapally Tejaswi 
Published: August 2019

Abstract
In this work, an ab-initio method is used to study few-photon ionisation of helium with linearly and circularly polarized light. The photoionization cross sections are estimated from the ionization yields calculated by directly propagating the time-dependent Schrödinger equation (TDSE) and are compared with those obtained from the lowest-order (non-vanishing) perturbation theory (LOPT). The results show a clear deviation of the TDSE yields from those of the LOPT as well as the dominance of the linearly-polarized ionization yields over the circularly polarized ones, towards higher field intensities.

Published: August 2019

Abstract
In this work, we present measurements of the intensity-dependent photoelectron spectrum of Kr irradiated by the FLASH FEL tuned to a photon energy of 25.8 eV. Intensity dependent photoelectron spectra were obtained with the aid of a Velocity Map Imaging (VMI) spectrometer. As the FEL photon energy is close to threshold, two photon sequential double ionization is favoured. The number of open channels is kept to a minimum and leading to a simple description of the process.
Laser-Induced Plasma Analysis for Surrogate Nuclear Debris
Authors: Shattan M B , Auxier J D , Stowe A C , Parigger C G 
Published: August 2019

Abstract
This work identifies analytical lines in laser-induced plasma for chemical analyses of major elements found in surrogate nuclear debris. These lines are evaluated for interferences and signal strength to insure they would be useful to measure relative concentrations. Compact, portable instruments are employed and can be included as part of a mobile nuclear forensics laboratory for field screening of nuclear debris and contamination. The average plasma temperature is measured using the well-established Boltzmann plot technique, and plasma’s average electron density is determined using empirical formulae based on Stark broadening of the H-alpha line. These measurements suggest existence of partial local thermal equilibrium.
A compact Fourier transform spectrometer with no moving parts for laser induced breakdown spectroscopy
Authors: Davitt S J , Costello J T , Kelly T J 
Published: August 2019

Abstract
We report the development of a portable single-shot Fourier transform spectrometer for application in laser induced breakdown spectroscopy (LIBS) with a particular emphasis on remote or standoff LIBS. The device, based on a design by Harvey and Padgett[1], has a number of inherent features that give it performance advantages over a portable grating spectrometer, in particular a gain in signal to noise ratio (SNR). Tests with low-pressure discharge lamps show a gain in SNR of at least five times that of a traditional portable grating spectrometer in stand-off mode. In addition, the instrument has also demonstrated the ability to measure the spectrum from a short or ultrashort pulsed source in a single shot, e.g. a laser produced plasma.

Published: August 2019

Abstract
At present, the technological stage of the development of society is intended to establish the priority of the method over the result of activity. Therefore, society needs a comprehensive approach to the choice of intellectual and material ways of its activities from the mass of alternative options and to the evaluation of its results. In this vein, technological culture is a value aspect of modern and future education. It is characterized by multidimensionality, creative character and includes not only production, but also sociocultural aspects. Technological culture includes such personal qualities of a person, which allow technologically competently to solve any problems from the fields of activity of the engineer. In addition, creative solutions of social and economic problems depend on the degree of formation of character and qualities that characterize the future orientation of the personality of future specialists. Therefore, technical universities are faced with the task of developing the qualifications of university graduates in the professional sphere, creating conditions for the development of such personal qualities as creative self-development, humanitarian and technical outlook, intellectual maturity, responsibility. In the existing practice of teaching specialized technical disciplines, the process of introducing the fundamentals of technological culture, unfortunately, is sometimes very difficult. In these cases, it is necessary to overcome the inertia of technocratic thinking and the lack of understanding of the importance of the idea of developing a technological culture and the personal properties and qualities that are significant for it.

Reverse priority mechanisms in allocation of resources
Authors: Rossikhina L V , Kalach A V , Borsuchenko S A , Golovkin R B , Mamedov S N 
Published: August 2019

Abstract
The paper describes a problem of allocation of a limited resource under the conditions of probabilistic indeterminacy as related to the quantity of resource allocated. The active system consists of the Center and consumers (agents). The Center has a resource being allocated among the consumers based on their requests. When requests are announced, the consumers have information only on the function of allocation of resource being allocated by the Center. The priority mechanisms of resource allocation based on the reverse priority principle (the priority function is a decreasing request function) are studied for a deterministic case when the amount of resource available at the Center is known by the consumers as well as under the conditions of probabilistic indeterminacy. Nash Equilibria are determined for different priority functions provided the objective functions of consumers increase monotonically in relation to the resource quantity. A business game is proposed to study the mechanism of reverse priorities in resource allocation problems (deterministic and probabilistic cases). Informal and formal descriptions of games are included. Gaming algorithm is proposed. The results of experiments are presented for deterministic and probabilistic cases with different priority functions, which confirm the key theoretical conclusions.

Physical characteristics of the seeds layer and estimation of the degree of the activator volume
Authors: Rubtsova Elena , Starodubtseva Galina , Vanina Anna , Lyubaya Svetlana 
Published: August 2019

Abstract
Analysis of the results of scientific research suggests that the authors used small volumes of the seed layer to study the effect of an electric field on the seeds. The electrical parameters of the seed layer in a small-sized activator allowed the authors to freely operate with a wide range of impact signals. When switching to the industrial level in the activator, a large volume of a layer of seeds is processed. The actual electrical parameters of the power source, activator, and seed layer limit the range of electrical parameters of possible effects. Therefore, for the industrial development of these electrical technologies, it is necessary to adjust the previously determined parameters of the seed treatment modes. The positive effect of the electric field on the seeds is due to the quantitatively dosed energy impact. However, the assessment of the impact on any one of the electrical parameters (electric field intensity, frequency, etc.) is insufficient. The cause is non-uniform processing of the seed layer. The rational thickness of the seed layer and its maximum compaction in the volume of the activator make it possible to create a uniform electric field strength of the required size and, as a result, an appropriate dose of exposure to increase the sowing qualities of the seeds. For the formation of electrical parameters and the description of the processes occurring in the activator in the presence of a moving seed layer, it is necessary to take into account a number of factors. One of the important factors is the structure of the seeds of plants. The structural and functional unit of a seed is a cell that has, in addition to its biological, chemical properties, a number of physical characteristics. The heterogeneity of the composite components of different seed mass determines its physical properties. These features are also taken into account when developing technological schemes for the operation of an activator with a moving layer.

Abstract
Expansion of urbanized areas and activity of technogenic systems led to the emergence and operation of a set of environmental factors that determine the flow of life processes in new conditions. Under the influence of anthropogenic factors including man-made (industry, energy, transport) and economic activities (construction, utilities, recreational load) in the environment, a number of environmental problems arise and develop, aggravated by unfavourable weather conditions for dispersion of harmful impurities in the air, which is especially important for Krasnoyarsk city. Biological monitoring is necessary to assess the environmental consequences of human impact, to ensure the necessary level of environmental quality and the environmental safety of the urban environment. Recently, researchers have been analysing the degree of impact of environmental factors through developmental sustainability (fluctuating asymmetry). This paper shows an assessment of the stability of the development of tree plantations growing in the zone of influence of an aluminium plant and heat and power engineering enterprises. For the study the most common tree species were selected, which are widely used for landscaping cities: apple berry, wild cherry, balsam poplar, elm squat. The representativeness of the data obtained is confirmed by appropriate statistical processing. Morphometric indicators of the lamina (j3, j4, j5) of apple and berry apple trees sensitive to negative environmental factors, intensified under the influence of emissions from an aluminum plant, are revealed. An identical response of indicator species belonging to the same family was found.

Published: August 2019

Abstract
Effectiveness assessment of modern technologies and machines introduction is one of the most important economic objectives in agricultural production. The purpose of this paper is to develop a formalized effectiveness evaluation system of introduction of modern technologies and machines in crop production. This system is based on the use of modern software for creation of crop production process flow diagrams, business planning, and optimization of machines and technologies parameters. It is proposed to formulate the process of economic effectiveness evaluation of new technologies in crop production as a permanent operating three-stage indiscrete cyclic model for a particular industry, facility, district or region. In the first stage of calculations income and expenses staggered over a period of time and obtained through the new technologies or more modern tools are defined, using detailed process flow diagrams, fodder balance and other estimation forms. During the second stage project success criteria are determined by calculation of stability analysis and evaluation of feasibility and effectiveness of new technologies. Finally, in the third stage it is necessary to solve a task of introduced technologies parameters adaptation and optimization. The effectiveness evaluation system of introduction of modern technologies and machines in crop production, proposed in this paper, allows for quicker decision making regarding reasonability of replacing machines and technologies with new ones.

Published: August 2019

Abstract
The concept of sustainable agriculture is one of the directions of the state’s national security strategy, which is determined by economic, social, environmental and political factors. Sustainable development of the region directly affects the sustainable development of the state, and sustainable development of the region; in its turn it directly depends on the sustainable development of individual industries, among which dairy cattle breeding is the leading one. The total milk production in Russia as a whole in farms of all categories reached a record high of 31.5 million tons (+2.5% in the country and +2.6% in the Krasnoyarsk Territory). However, the annual milk consumption per capita in 2017 in the Russian Federation was 233 kg, in the Krasnoyarsk Territory it was a little less than this Russian indicator (231 kg, which is 71% lower than 325 kg which is the standard recommended by the Ministry of Health of the Russian Federation), which indicates a low level of milk self-sufficiency. The level of the country’s milk production development is determined by the production state in its regions, which in turn depends on their territorial location, climatic conditions, natural-historical features of the territories, etc. Since a large number of enterprises is involved in milk production in the region, production should be considered in the context of municipal districts, which makes it possible to identify the most promising clusters from the standpoint of the production potential formation of the dairy cattle breeding industry in the Krasnoyarsk Territory.

Abstract
The formula for a membrane solution with antioxidant and antimicrobial spectrum has been developed. 4% of agar agar, and 2% of glycerol were used as the main ingredients of the membrane solution, 1% of food additive arabinogalactan (E 409) was used as an antioxidant, and 0.02% of antibiotic nisin was used as an antimicrobial agent. These ingredients were diluted with distilled water to 100%. Addition to the basic formula of the membrane arabinogalactan makes it possible to increase strength and elongation. The biodegradability of the membrane when placed in a 0.5% solution of hydrochloric acid, containing all the enzymes of gastric juice was 25.4 minutes. It was found that samples of chilled meat packed in the developed membrane after 10 days of refrigerated storage corresponded to fresh organoleptic, physicochemical and microbiological indicators. Acid and peroxide numbers of fat samples were within normal limits. As a result, it was revealed that the packaging of chilled meat in the developed membranes helps prevent microbial and oxidative damage to the product, which allows positioning it for implementation in the agro-industrial complex.
