description: We consider $M$-theory compactified on $T^4 \times T^2$ and describe the count of spinning $1/8$-BPS states. This refines the classic count of Maldacena-Moore-Strominger in the physics literature and the recent mathematical work of Bryan-Oberdieck-Pandharipande-Yin, which studied reduced Donaldson-Thomas invariants of abelian surfaces and threefolds. As in previous work on $K3 \times T^2$ compactification, we track angular momenta under both the $SU(2)_L$ and $SU(2)_R$ factors in the 5d little group, providing predictions for the relevant motivic curve counts.
Universities as Urban Anchors: Examining the Socio-Economic Impact and Support Dynamics in Italy
Creators: name: Laudisa, Federica
Publisher: name: Urbana

description: What does it mean for a city to be a university city? In other words, what impact do universities have on the areas in which they reside? Universities undoubtedly have important direct and indirect effects on local economies. The direct economic effects are driven in large part by the student population. In Piedmont, for instance, a combined total of over 130,000 students are enrolled in the region’s four universities, with 42,000 of them coming from outside the region. That’s roughly the population of a mid-sized Italian town. And according to a 2020 estimate by IRES Piemonte, these 42,000 students spend an average of 800 million euros per year on food, lodging, school supplies, recreational-sports activities, and transportation, determining a substantial economic return to the region. Even more striking is the universities’ indirect economic contribution. According to data from the Rosselli Foundation, universities in the Turin metropolitan area make up the region’s fourth most productive sector in Piedmont in terms of indirect economic impact, ranking just behind the construction, transportation, and agricultural sectors, with a total estimated value of nearly 2 billion euros. The economic advantages of having a university located in the community have not escaped the notice of local administrations, who are eager to encourage the establishment of university programmes not just in large cities, but also in smaller towns.

description: Future wireless networks are envisioned to integrate multi-hop, multi-operator, multi-technology (m3) components in order to meet the increasing traffic demand at an acceptable price for subscribers. The performance of such a network depends on the multitude of parameters defining traffic statistics, network topology/technology, channel characteristics and business models for multi-operator cooperation. So far, most of these aspects have been addressed separately in the literature. Since the above parameters are mutually dependent, and simultaneously present in a network, for a given channel and traffic statistics, a joint optimization of technology and business model parameters is required. In this paper, we present such joint models of complex wireless networks and introduce optimization with parameter clustering to solve the problem in a tractable way for large number of parameters. By parameter clustering we compress the optimization vector and significantly simplify system implementation, hence the algorithm is referred to as compressed control of wireless networks. Two distinct parameter compression techniques are introduced mainly parameter absorption and parameter aggregation. Numerical results obtained in this way demonstrate clear maximum in the network utility as a function of the network topology parameters. The results, for a specific network with traffic offloading, show that the cooperation decisions between the multiple operators will be significantly influenced by the traffic dynamics. For typical example scenarios, the optimum offloading price varies by factor 3 for different traffic patterns which justifies the use of dynamic strategies in the decision process. Besides, if user availability increases by multi-operator cooperation, network capacity can be increased up to 50% and network throughput up to 30-40%.

Felt knowing, tacit knowledge and creative practice: insights from architects and private developers in urban settings
Creators: name: McCauley, Kate C.
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This thesis looks closely at architectural design and private developer practice in relation to public sector urban planning practice. In particular, it focuses on experiential aspects of how practitioners from each of these distinct practice traditions, who work in similar contexts but under different conditions, do what they do. Analysis is undertaken at a particularly fine resolution, exploring the phenomenology of their practices using constructivist grounded theory (Charmaz 2006). This allows the thesis to build a grounded theory in the form of a partial model of practices used by the participants, as they transition back and forth between feeling, thinking and doing in their professional practices. The research delivers three main findings : (i) fine resolution practices described in different settings by Gendlin (1996), Petitmengin‐Peugeot (1999) and Walkerden (2005) are echoed in skilful architectural and property developer practice; (ii) elements of a family of gestures involving problem‐solving, designing and negotiating can usefully be delineated in the practices of private developers and architects; and (iii) there are resonances between the practices of private sector architects and developers, and public sector urban planners (including designers) which open up new possibilities for knowledge sharing and provoking creativity amongst practice traditions affecting urban futures. These findings are significant because they complement and contribute to recent work in communicative planning. Forester (1989) identified conversational practices that support an understanding of urban planning as communicative (building on the work of Habermas 1984), and identified the importance of conversation – dialogue, debate and deliberation – as a platform for ‘making sense together’. This research identifies more interiorly‐oriented practices that support creative responses to challenges of urban planning and private development and in integrative ways. The thesis concludes that better understanding how practice operates complements Forester’s emphasis on the social aspects of making sense, and also advances the emphasis on democratic process and social justice in communicative planning. Finally, the thesis considers how these findings open new opportunities for developing a teachable model of the microprocesses of practices identified in the mappings of modes of practice presented.

description: The primary objective of the Dissemination, Communication, and Exploitation Plan is to promote the acceptance and uptake of the EOSC Open Science Observatory by key actor groups across Europe. This document represents the first version of the Dissemination, Communication, and Exploitation Plan and will be updated in M18 to reflect the evolving needs of the project and its stakeholders, ensuring that our strategies remain effective and responsive to the dynamic Open Science landscape. For the EOSC Track project, we have identified five primary audience segments: stakeholders, partners, end-users, and the general public. To achieve our communication and dissemination objectives, we will utilize a variety of channels, each chosen to target specific audience segments and deliver tailored messages effectively. The exploitation plan for the EOSC Track project is designed to leverage the project’s outcomes and further its objectives. The primary aim is to establish a robust monitoring and evaluation infrastructure for Open Science, utilizing the EOSC Open Science Observatory as a central tool. 

The exploitation plan is strategically structured into two complementary strands: the technical exploitation of tools and services, and the adoption and implementation of monitoring frameworks and indicators. To effectively measure the progress and success of the EOSC Track project, a comprehensive set of Key Performance Indicators (KPIs) has been established. These KPIs provide clear targets and deadlines, ensuring that the project stays on track and achieves its objectives. The KPIs cover various areas of the project, detailing specific goals and timelines to guide the team’s efforts and ensure accountability. By implementing this strategic approach, the EOSC Track project aims to advance Open Science practices, create a collaborative research ecosystem, and ensure the long-term sustainability and impact of the EOSC Open Science Observatory across Europe.

description: The IEC 61499 reference model provides an international standard developed specifically for supporting the creation of distributed event-based automation systems. Functionality is abstracted into function blocks which can be coded graphically as well as via a text-based method. As one of the design goals was the ability to support distributed control applications, communication plays a central role in the IEC 61499 specification. In order to enable the deployment of functionality to distributed platforms, these platforms need to exchange data in a variety of protocols. IEC 61499 realizes the support of these protocols via "Service Interface Function Blocks" (SIFBs). In the context of smart grids and energy applications, IEC 61499 could play an important role, as these applications require coordinating several distributed control logics. Yet, the support of grid-related protocols is a pre-condition for a wide-spread utilization of IEC 61499. The eXtensible Messaging and Presence Protocol (XMPP) on the other hand is a well-established protocol for messaging, which has recently been adopted for smart grid communication. Thus, SIFBs for XMPP facilitate distributed control applications, which use XMPP for exchanging all control relevant data, being realized with the help of IEC 61499. This paper introduces the idea of integrating XMPP into SIFBs, demonstrates the prototypical implementation in an open source IEC 61499 platform and provides an evaluation of the feasibility of the result.

description: Let $(M,g)$ be a smooth Riemannian manifold and $\mathsf{G}$ a compact Lie group acting on $M$ effectively and by isometries. It is well known that a lower bound of the sectional curvature of $(M,g)$ is again a bound for the curvature of the quotient space, which is an Alexandrov space of curvature bounded below. Moreover, the analogous stability property holds for metric foliations and submersions. The goal of the paper is to prove the corresponding stability properties for synthetic Ricci curvature lower bounds. Specifically, we show that such stability holds for quotients of $\mathsf{RCD}^{*}(K,N)$-spaces, under isomorphic compact group actions and more generally under metric-measure foliations and submetries. An $\mathsf{RCD}^{*}(K,N)$-space is a metric measure space with an upper dimension bound $N$ and weighted Ricci curvature bounded below by $K$ in a generalized sense. In particular, this shows that if $(M,g)$ has Ricci curvature bounded below by $K\in \mathbb{R}$ and dimension $N$, then the quotient space is an $\mathsf{RCD}^{*}(K,N)$-space. Additionally, we tackle the same problem for the $\mathsf{CD}/\mathsf{CD}^*$ and $\mathsf{MCP}$ curvature-dimension conditions. We provide as well geometric applications which include: A generalization of Kobayashi's Classification Theorem of homogenous manifolds to $\mathsf{RCD}^{*}(K,N)$-spaces with essential minimal dimension $n\leq N$; a structure theorem for $\mathsf{RCD}^{*}(K,N)$-spaces admitting actions by large (compact) groups; and geometric rigidity results for orbifolds such as Cheng's Maximal Diameter and Maximal Volume Rigidity Theorems. Finally, in two appendices we apply the methods of the paper to study quotients by isometric group actions of discrete spaces and of (super-)Ricci flows.

description: Temporal Convolutional Networks (TCNs) are promising Deep Learning models for time-series processing tasks. One key feature of TCNs is time-dilated convolution, whose optimization requires extensive experimentation. We propose an automatic dilation optimizer, which tackles the problem as a weight pruning on the time-axis, and learns dilation factors together with weights, in a single training. Our method reduces the model size and inference latency on a real SoC hardware target by up to 7.4x and 3x, respectively with no accuracy drop compared to a network without dilation. It also yields a rich set of Pareto-optimal TCNs starting from a single model, outperforming hand-designed solutions in both size and accuracy.

description: We present the first X-ray observations of the eclipsing cataclysmic variables Lanning 386 and MASTER OTJ192328.22+612413.5, possible SW Sextantis systems. The X-ray light curve of Lanning 386 shows deep eclipses, similar to the eclipses seen in the optical light curve, confirming the high inclination of the system. There is evidence of a periodicity between 17-22 min in the X-ray and optical light curves of Lanning 386, which is associated with quasi-periodic oscillations. This system also displays a hard X-ray spectrum which is well fit by a partially covered, absorbed 2 temperature plasma. The cool plasma temperature (0.24$^{+0.17}_{-0.08}$ keV) and hot plasma temperature (9$^{+4}_{-2}$ keV) are not atypical plasma temperatures of known intermediate polar systems. Based on this model, we suggest that Lanning 386 is an intermediate polar with a high accretion rate. The hot plasma temperature limits the white dwarf mass to $>$0.5 M$_{\odot}$. From the optical spectrum obtained using the Large Binocular Telescope, we find that the secondary in the system is consistent with an M5V star, and refine the distance to Lanning 386 to be 160$\pm$50 pc. Finally, we use the high time resolution of the optical spectra to crudely constrain the magnetic moment of the white dwarf in Lanning 386. J1923 was not detected during the observations, but the upper limit on the flux is inline with J1923 and Lanning 386 being related.

Globalisation and convergence of accounting: a contextual analysis of issues, attitudes and their implications in the German context
Creators: name: Heidhues, Eva

Year: 2022
Subjects: Other education not elsewhere classified

description: This thesis provides a holistic examination of convergence with the adoption of International Financial Reporting Standards (IFRS) in Germany by taking into account the influence of political, legal, economic, social, cultural and historical factors on accounting principles and practices. Specifically, this study examines issues in the convergence process that may create constraints in achieving global comparability and importantly may challenge the International Accounting Standards Board’s (IASB) main objective, namely, ‘to develop, in the public interest, a single set of high quality, understandable, enforceable and globally accepted financial reporting standards based on clearly articulated principles’ (IFRS Foundation 2011a, Preface to IFRS). In contrast to a significant number of prior research that has largely focused on quantifiable and narrowly focused theoretical approaches, this thesis provides a holistic examination with an emphasis on multi-disciplinary perspectives. The contextual analysis contributes to international accounting research by providing deeper and sharper insights into the convergence process as well as potential challenges and constraints to future development of IFRS and the IASB. Specifically, the findings show that international politics and power structures have an increasing influence on Germany’s national accounting developments often without adequate consideration of normative evaluations by German stakeholders, which may result in challenges to future development and acceptance of IFRS in Germany. Moreover, the findings provide evidence of specific concerns regarding the political nature of the IASB, the technical superiority of IFRS and the extensive use of professional judgements in IFRS. These concerns are further substantiated by evidence that professional accountants from Germany and Italy show systematic differences in their exercise of professional judgment, which raises concerns about the potential to achieve the IASB’s main objective of international comparability of financial reporting. Accounting researchers, practitioners, educators and accounting standard setters are likely benefit from these insights that show the importance of contextual factors in the convergence process. Indeed, the findings contribute to international accounting research and practice by emphasising that convergence is a complex social and political process that requires researchers to critically examine contextual environments of countries rather than simply focus on measurement, quantification, simplification and categorisation.

Living on the edge: ecological and evolutionary mechanisms of range expansion in invasive species

Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: Despite ongoing research into traits of successful invasive species, few studies have examined how selection on such traits change during the course of an invasion. This is despite increasing recognition that populations in the invaded range are generally not at equilibrium and many invasive species are still undergoing range expansion. As a species expands in its range from its range core where it was first introduced, populations at the edge of the range may experience different ecological (e.g. fewer enemies) and evolutionary conditions (i.e. selection for increased dispersal, growth and reproduction). Changes in these conditions towards range edges may facilitate continual range expansion and examining how such selective pressures vary across the range of invasive species may increase our understanding of factors determining species' ranges. This thesis explores the ecological and evolutionary mechanisms of range expansion in exotic invasive species using two coastal exotic dune plants (Gladiolus gueinzii Kunze (Iridaceae) and Hydrocotyle bonariensis Lam. (Apiaceae)) occurring along eastern Australia. In particular, it examines variation in enemy attack across ranges (Chapter 2) as well as selection for increased growth (Chapter 3), dispersal (Chapter 4) and reproduction (Chapter 5) towards range edges to facilitate further range expansion. Both H. bonariensis and G. gueinzii did not show consistent responses in terms of enemy release and trait shifts towards range edges. Hydrocotyle bonariensis experienced increased enemy attack and growth towards range edges however there were no such differences towards range edges for G. gueinzii. These inconsistent responses highlight the complexity of understanding factors influencing range expansion within and across species and provide a rich avenue for continued research.

description: Identifying and modeling of biological systems is very useful to understand cell's dynamic. To know what really happens inside the cell we need to observe the state of a cell. In fact observability is a structural property of a control system defined as the possibility to deduce the state of the system from observing its input-output behavior. Any complex cell model is a combination of some minimal models which are simpler than complex cell model because they have two dimensions. These models can describe the behavior of the cell. The property of observability for nonlinear systems is very useful in analyzing such systems. This paper deals with the observability of minimal cell models. Based on the fact that the minimal cell models are nonlinear, analyzing the property of these models need nonlinear methods. The method has been used for observability is Lie Derivative. The results indicate observability of minimal cell models.

description: We consider the global consensus problem for multi-agent systems with input saturation over digraphs. Under a mild connectivity condition that the underlying digraph has a directed spanning tree, we use Lyapunov methods to show that the widely used distributed consensus protocol, which solves the consensus problem for the case without input saturation constraints, also solves the global consensus problem for the case with input saturation constraints. In order to reduce the overall need of communication and system updates, we then propose a distributed event-triggered control law. Global consensus is still realized and Zeno behavior is excluded. Numerical simulations are provided to illustrate the effectiveness of the theoretical results.
Functional ecological processes in upland swamps and chain of ponds systems in the Blue Mountains and Southern Highlands of eastern New South Wales, Australia

description: Globally, biodiversity is declining, leading to concerns of permanent loss of ecosystems, central to which is the increasing strength of evidence for the inextricable linkage between biodiversity and ecosystem function. There is an urgent research need to identify the crucial relationships between biodiversity and the functions they require and provide. Many Australian aquatic ecosystems are still poorly studied, including remote and atypical streams, rare and groundwater ecosystems. Furthermore, even in systems where biodiversity is known, ecological functions have rarely been examined. By investigating functional attributes alongside biodiversity measures it was possible, through a sequence of studies to more fully understand dynamics of two rare and at-risk wetland systems west of the Sydney Basin in eastern NSW, Australia. The aquatic ecology and function of Blue Mountains upland peat swamps as part of the THPSS (Temperate Highland Peat Swamps on Sandstone) and Mulwaree ‘chain-of-ponds’ are little known. They represent fundamentally different ecosystems, but both face growing anthropogenic pressure. These studies highlighted the importance of including functional indicators into biodiversity studies as a way of gaining better information for restoration and management. The THPSS swamps were porous to pollutants, with groundwater and streams downstream carrying stormwater nutrients. Leaf litter and cotton strip decay rates were very low, invertebrate abundances were low, but urban stormwater increased both. Release of excavated naturally occurring ironstone, combined with nutrients and high groundwater, led to proliferation of iron bacteria, complex redox reactions, anoxia and reduced productivity. The Mulwaree chain-of-ponds are geomorphic anomalies that act as mesotrophic monomictic lakes once disconnected from river flows. The ponds maintain significant aquatic macrophyte biodiversity, which maintains unusual clear water conditions. The majority of macrophytes are perennial rhizomatous species, but some, such as Water Ribbons (Cycnogeton procerum) are at risk due to water borne dispersal. Water ribbons play a pivotal role in maintaining macrophyte dominance and in carbon cycling within the ponds.

description: In this paper we present a mathematical and numerical framework for a procedure of imaging anisotropic electrical conductivity tensor by integrating magneto-acoutic tomography with data acquired from diffusion tensor imaging. Magneto-acoustic Tomography with Magnetic Induction (MAT-MI) is a hybrid, non-invasive medical imaging technique to produce conductivity images with improved spatial resolution and accuracy. Diffusion Tensor Imaging (DTI) is also a non- invasive technique for characterizing the diffusion properties of water molecules in tissues. We propose a model for anisotropic conductivity in which the conductivity is proportional to the diffusion tensor. Under this assumption, we propose an optimal control approach for reconstructing the anisotropic electrical conductivity tensor. We prove convergence and Lipschitz type stability of the algorithm and present numerical examples to illustrate its accuracy and feasibility.

description: Сырцовые пряники с фруктовой начинкой относятся к мучным кондитерским изделиям с промежуточной влажностью, для которых характерен высокий риск микробиологической порчи в процессе хранения. Прогнозирование порчи таких изделий проведено на основании результатов исследований процессов влагопереноса между частями целого изделия. Установлено, что скорость миграции влаги из изделия в окружающую среду не является постоянной и изменяется от +3,5 до -5,0 % в неделю. В процессе хранения пряников активность воды повышается в результате деградации крахмала, количество «свободной» влаги увеличивается. При увеличении толщины пленки скорость миграции влаги в окружающую среду уменьшается, а относительная влажность воздуха внутри упаковки увеличивается, активность воды поверхностного слоя пряника остается на уровне более 0,7. На 10-й неделе хранения активность воды достигла максимума и составила 0,82. Скорость изменения массовой доли влаги различных частей пряников в процессе их хранения изменяется в диапазоне от +3,5 до -5,0 % в неделю. В течение 4 недель хранения сырцовых пряников при уменьшении массовой доли влаги активность воды также уменьшается. При этом активность воды остается на высоком уровне - 0,71-0,74, достаточном для развития плесеней. Риск плесневения поверхности пряников существенно повышается и зависит от исходной микробиологической обсемененности сырья, использованного для изготовления пряников. Установлено значительное увеличение содержания плесеней от 0 КОЕ/г для исходных пряников до 6×104 КОЕ/г на 7-й неделе хранения. Полученные результаты могут быть использованы для прогнозирования сохранности кондитерских изделий с промежуточной влажностью.

description: В контроле качества и безопасности алкогольной продукции чрезвычайно важным и актуальным направлением является разработка аналитических методик, которые крайне востребованы как предприятиями-производителями для проведения рутинных анализов, так и контролирующими инстанциями для осуществления контроля. Целью настоящего исследования являлось изучение возможности разработки методики определения катионного состава виски методом капиллярного электрофореза. Для детектирования выбран бесконтактный кондуктометрический детектор с пределом детектирования 10-7-10-9 моль/л. Составлены модельные растворы массовой концентрацией 0,5-15,0 мг/дм3 аммония, калия, кальция, магния, натрия. Подобрана композиция буферного раствора, содержащая гистидин (HIS), 2-морфолиноэтансульфоновую кислоту (MES), краун-эфир (18-Crown-6). Найдены оптимальные режимные параметры электрофоретического разделения: длина капилляра - 80 см, ввод пробы гидродинамический, время ввода пробы - 15-25 сек, давление ввода пробы - 30 мБар, напряжение - 20-30 кВ, время анализа - 5-7 мин. В ходе серии экспериментов испытано несколько вариантов концентраций модельных растворов и реализованы различные композиции электролитов, получены электрофореграммы модельных растворов. Определены последовательность выхода, время удерживания компонентов, рассчитано среднее время удерживания. Установлено, что диапазон отклонений времени выхода компонентов колеблется в интервале 0,02-0,05 мин, воспроизводимость времени удерживания составляет не более 1 %. В результате исследований выявлена и экспериментально подтверждена техническая возможность дифференцированной идентификации ионов аммония, калия, кальция, натрия, магния в виски методом капиллярного электрофореза с кондуктометрическим детектированием. В найденных условиях проведен качественный анализ виски, представленных на рынке алкогольной продукции, получены электрофореграммы. Работа по развитию и совершенствованию данного направления будет продолжена в нескольких векторах. Предложенное решение позволит расширить перечень нормируемых физико-химических показателей, что будет способствовать выявлению фальсификаций, а также контролировать качество алкогольной продукции на новом уровне.

description: We initiate the study of degree-bounded network design problems in the online setting. The degree-bounded Steiner tree problem { which asks for a subgraph with minimum degree that connects a given set of vertices { is perhaps one of the most representative problems in this class. This paper deals with its well-studied generalization called the degree-bounded Steiner forest problem where the connectivity demands are represented by vertex pairs that need to be individually connected. In the classical online model, the input graph is given online but the demand pairs arrive sequentially in online steps. The selected subgraph starts off as the empty subgraph, but has to be augmented to satisfy the new connectivity constraint in each online step. The goal is to be competitive against an adversary that knows the input in advance. We design a simple greedy-like algorithm that achieves a competitive ratio of O(log n) where n is the number of vertices. We show that no (randomized) algorithm can achieve a (multiplicative) competitive ratio o(log n); thus our result is asymptotically tight. We further show strong hardness results for the group Steiner tree and the edge-weighted variants of degree-bounded connectivity problems. Fourer and Raghavachari resolved the online variant of degree-bounded Steiner forest in their paper in SODA'92. Since then, the natural family of degree-bounded network design problems has been extensively studied in the literature resulting in the development of many interesting tools and numerous papers on the topic. We hope that our approach in this paper, paves the way for solving the online variants of the classical problems in this family of network design problems.

description: Исследования по пневмоклассификации измельченного подсолнечного, льняного и конопляного жмыхов проводили на экспериментальной установке при окружной скорости классификатора 15,3; 16,4 и 17,5 м/с, при окружной скорости диспергатора 78 м/с. Установлено, что увеличение окружной скорости классификатора приводит к увеличению массы «легкой» фракции. Изменение окружной скорости классификатора с 15,3 м/с до 17,5 м/с позволило увеличить выход легкой фракции конопляного жмыха 2,5 %, а льняного - в 3,4 раза. Однако массовая доля легкой фракции при окружной скорости 17,5 м/с составила 8,2-8,5 % от исходной массы продукта, использованного для пневмоклассификации. Значительно легче проходил процесс пневмоклассификации подсолнечного жмыха, что связано с меньшей массовой долей жира - 1,07 % в конопляном и льняном жмыхах. Результаты зависимости выхода легкой фракции от окружной скорости классификатора при переработке подсолнечного жмыха аналогичны результатам пневмоклассификации льняного и конопляного жмыхов (увеличение окружной скорости классификатора с 15,3 до 17,5 м/с обеспечило увеличение выхода легкой фракции в 2,3 раза), но масса легкой фракции подсолнечного жмыха составила 18,5 %. Массовая доля белка в легкой фракции при увеличении окружной скорости классификатора до 17,5 м/с возросла для подсолнечного жмыха на 4 %, для льняного - на 14,8 %, для конопляного - на 14,3 % по сравнению с исходным продуктом. Массовая доля жира в легких фракциях льняного и конопляного жмыхов при увеличении окружной скорости классификатора уменьшилась до 1,5 %, а в легкой фракции подсолнечного жмыха возросла на 1 % по сравнению с исходным продуктом. Уменьшение массовой доли жира в легких фракциях льняного и конопляного жмыхов может объясняться потерями жира в роторе диспергатора. Отсутствие потерь жира в роторе диспергатора при пневмоклассификации подсолнечного жмыха приводит к увеличению его массовой доли в легкой фракции.
