Development of technology for producing wheat bread enriched with soy ingredient

Nutritional supplements produced from soy and being rich in protein, fat and many other valuable substances have become a promising source of fortification of bakery products. This study aimed to develop a technology for producing wheat bread enriched with a protein-vitamin-mineral ingredient (PVMI) obtained from germinated soybeans. When kneading the dough, PVMI was added together with wheat flour and other dry components. Mathematical modeling of the wheat bread sensory evaluation showed the optimal content of PVMI in the recipe was 20% of the weight of wheat flour. As a result of the correlation-regression analysis, the most rational production characteristics for obtaining bread enriched with BVMI have been established. The amount of protein in the bread sample increased by 71.9%, dietary fiber - by 40.9%, vitamin E - by 34.7%, vitamin B1 - by 190%, vitamin B2 - by 80%, choline - by 186%. The fat quantity was 4.1 times more. At the same time, the total carbohydrate content decreased by 18.1% compared to the control sample. The improved chemical composition makes it possible to classify wheat bread with PVMI as an enriched food product.

A study on detection of roving tension and fine control of yarn breakage

The fine control of yarn breakage is essential for the production of better yarn quality by reducing the tension fluctuationof roving. The detection of roving tension provides important information regarding the yarn formation during spinning.In the present work, we developed a device for roving-tension detection and regulation, which greatly reduces the yarnbreakage rate and improves the production efficiency of ring spinning. By analysing the factors affecting the rovingtensions, we used a signal acquisition system in conjunction with the tension detection device to regulate the spindlerotate speed to realize the fine control of yarn breakage. Our results indicate that the proposed method can ensure auniform spinning tension of the yarn in ring spinning, which significantly reduces the yarn breakage rate, and boost theyarn production. Our work paves the way toward the rational production of high-quality yarn

Limits to the Rational Production of Discourse Connectives

Rational accounts of language use such as the uniform information density hypothesis, which asserts that speakers distribute information uniformly across their utterances, and the rational speech act (RSA) model, which suggests that speakers optimize the formulation of their message by reasoning about what the comprehender would understand, have been hypothesized to account for a wide range of language use phenomena. We here specifically focus on the production of discourse connectives. While there is some prior work indicating that discourse connective production may be governed by RSA, that work uses a strongly gamified experimental setting. In this study, we aim to explore whether speakers reason about the interpretation of their conversational partner also in more realistic settings. We thereby systematically vary the task setup to tease apart effects of task instructions and effects of the speaker explicitly seeing the interpretation alternatives for the listener. Our results show that the RSA-predicted effect of connective choice based on reasoning about the listener is only found in the original setting where explicit interpretation alternatives of the listener are available for the speaker. The effect disappears when the speaker has to reason about listener interpretations. We furthermore find that rational effects are amplified by the gamified task setting, indicating that meta-reasoning about the specific task may play an important role and potentially limit the generalizability of the found effects to more naturalistic every-day language use.

ECONOMIC ASPECTS OF ECOLOGICAL AGRICULTURAL PRODUCTION

The theoretical and practical directions of development of ecological agriculture in the country are justified, based on the idea of closed cycle, which corresponds to ecological and economic principles. The works of domestic and foreign scientists on this issue were studied. The main economic indicators of agricultural production on the example of Pavlodar region were analyzed: dynamics of gross output of agricultural sector; the number of operating agricultural enterprises and peasant (private) farms; distribution of the land fund by land categories. Information on violation of environmental legislation in the field of land resources protection and on the volume of waste in the industry is provided. The problems that hinder the implementation of the main provisions of greening of production activities in agro-industrial complex are identified. Summarizing the arguments of domestic and foreign scientists, the need to develop and implement the mechanism of functioning of agricultural entities is shown, which is based on the use of secondary resources, implementation of which in the future will allow, using comprehensive analysis of the used technologies, to modernize the production capacities of processing enterprises, implementing the principle of minimizing waste, ensuring expansion of the market for environmenttally friendly products. Models of rational production are shown: outsourcing and in sourcing. Measures of public support for the use of environmental innovations, environmental insurance, public-private partnership instruments, strengthening control over compliance with the principles of rational environmental management, economic incentives for agricultural producers are proposed.

Monitoring the Production of High Diffraction-Quality Crystals of Two Enzymes in Real Time Using In Situ Dynamic Light Scattering

The reproducible preparation of well-diffracting crystals is a prerequisite for every structural study based on crystallography. An instrument called XtalController has recently been designed that allows the monitoring of crystallization assays using dynamic light scattering and microscopy, and integrates piezo pumps to alter the composition of the mother liquor during the experiment. We have applied this technology to study the crystallization of two enzymes, the CCA-adding enzyme of the psychrophilic bacterium Planococcus halocryophilus, and the lysozyme from hen egg white in the presence of a synthetic chemical nucleant. We were able to (i) detect early nucleation events and (ii) drive the crystallization system (through cycles of dissolution/crystallization) toward growth conditions yielding crystals with excellent diffraction properties. This technology opens a way to the rational production of samples for crystallography, ranging from nanocrystals for electron diffraction, microcrystals for serial or conventional X-ray diffraction, to larger crystals for neutron diffraction.

Methods for creating CLT Construction Guidelines

During the past decade, the use of Cross-Laminated Timber (CLT) elements has become gradually more popular and widespread in building construction in Norway. A study mapping the experience of CLT use in the Norwegian construction industry reveals that existing domestic literature on this topic is outdated and no longer relevant. This paper describes the methods used for preparing updated CLT construction guidelines. Information obtained from expert actors in the construction industry, combined with document studies, has formed the knowledge basis for this study. A total of 19 qualitative in-depth interviews were conducted, and more than 400 documents from 12 CLT projects were received from 11 actors. A CLT construction guide focusing on moisture safety design and rational production was prepared based on the information obtained, and was quality assured by 16 experts from industry and the research community. Guidance on the approach to preparation of the guide, its format and layout, was provided by SINTEF Science Communication. Critical feedback influenced the content of the guide and its design recommendations. The study shows that dialogue with the construction industry and research community is a valuable contribution to the preparation of structured construction solutions. The involvement of the industry has accentuated the importance of the preparation of CLT construction guidelines. It is hoped that the guide will inspire research institutions to prepare and publish updated guidelines.
