title: Scale-resolving simulation of primary spray breakup in complex two-phase flow systems relevant to internal combustion engines
Creators: name: Pavlovic, Zoran
Publisher: name: UNSPECIFIED
Year: 2025

description: The objective of this work is to numerically investigate primary breakup phenomena under conditions relevant to automotive applications using Computational Fluid Dynamics (CFD) simulations. Primary breakup of a liquid jet is a complex process that is not yet fully understood. In this work, the high-fidelity, scale-resolving approach has been applied, namely Large Eddy Simulation (LES) and Partially Averaged Navier-Stokes (PANS) models have been used to directly resolve most of the turbulence spectrum and to capture the flow structure that could play an important role in jet break-up. The Coherent Structure Model (CSM) was used to represent the unresolved subgrid scales (SGS) within the LES framework, while the Scale Supplying Variable (SSV) variant of PANS was chosen for the PANS approach. The multiphase flow problem has been addressed using the Volume of Fluid (VOF) paradigm because of its robustness, mass conservativity and ability to maintain a sharp interface between the liquid and gas phases. 

The described simulation model, which is based on the numerical method of control volumes within the FIRE computational program of AVL List GmbH (Graz, Austria), has been applied to different flow configurations representative of industrial injector flows: 1) a circular liquid jet with a fully turbulent inlet profile, where the aim was to investigate the influence of inlet velocity and gas density on the liquid core length, 2) two different nozzle designs from the experiment of Balewski (PhD thesis, TU Darmstadt, 2009), where the aim was to get a deeper understanding of the correlation between turbulence and jet disintegration, 3) a low-pressure SCR injector operated at three different injection pressures, where the predictive power of the applied modes was confirmed; As part of this work, a tool for off-line coupling with Lagrangian Particle Tracking (LPT) simulations was developed, 4) a real GDI (gasoline direct injection) injector, which is particularly challenging due to the high injection velocity and the presence of cavitation.

All simulations performed provided plausible results that were in qualitative and quantitative agreement with the measurement results, suggesting that turbulence plays a very important role in the primary breakup process and that the influence of the internal nozzle design cannot be neglected in the spray characterisation. Despite certain limitations, high-fidelity CFD simulations can provide a deeper insight into the complex flow patterns and their impact on jet breakup, which can be useful to engineers involved in nozzle design development, and the results could be used as a basis for improving the accuracy of classical Lagrangian spray calculations.

description: A compounding feature of greater than 50% of all cancers is the high incidence of the cachexia syndrome, a complex metabolic disorder characterized by extreme weight loss due mainly to the gross depletion of skeletal muscle tissue. Although studies into the cause of cancer cachexia has spanned over multiple decades, little is known about the effects of various cancer treatments themselves on cachexia. For example, chemotherapy agents induce side effects such as nausea and anorexia, but these symptoms do not fully account for the changes seen with cancer cachexia. In this study we examine the effects of chemotherapeutic compounds, specifically, cisplatin in the colon-26 adenocarcinoma model of cancer cachexia. We find that although cisplatin is able to reduce tumor burden as expected, muscle wasting in mice nevertheless persists. Strikingly, cisplatin alone was seen to regulate muscle atrophy, which was independent of the commonly implicated ubiquitin proteasome system. Finally, we show that cisplatin is able to induce NF-κB activity in both mouse muscles and myotube cultures, suggesting that an additional side effect of cancer treatment is the regulation of muscle wasting that may be mediated through activation of the NF-κB signaling pathway.

description: The success of quantum optimal control for both experimental and theoretical objectives is connected to the topology of the corresponding control landscapes, which are free from local traps if three conditions are met: (1) the quantum system is controllable, (2) the Jacobian of the map from the control field to the evolution operator is of full rank, and (3) there are no constraints on the control field. This paper investigates how the violation of assumption (3) affects gradient searches for globally optimal control fields. The satisfaction of assumptions (1) and (2) ensures that the control landscape lacks fundamental traps, but certain control constraints can still introduce artificial traps. Proper management of these constraints is an issue of great practical importance for numerical simulations as well as optimization in the laboratory. Using optimal control simulations, we show that constraints on quantities such as the number of control variables, the control duration, and the field strength are potentially severe enough to prevent successful optimization of the objective. For each such constraint, we show that exceeding quantifiable limits can prevent gradient searches from reaching a globally optimal solution. These results demonstrate that careful choice of relevant control parameters helps to eliminate artificial traps and facilitate successful optimization.

description: Spin wave modes confined in a ferromagnetic film by the spatially inhomogeneous magnetic field generated by a scanned micromagnetic tip of a ferromagnetic resonance force microscope (FMRFM) enable microscopic imaging of the internal fields and spin dynamics in nanoscale magnetic devices. Here we report a detailed study of spin wave modes in a thin ferromagnetic film localized by magnetic field configurations frequently encountered in FMRFM experiments, including geometries in which the probe magnetic moment is both parallel and antiparallel to the applied uniform magnetic field. We demonstrate that characteristics of the localized modes, such as resonance field and confinement radius, can be broadly tuned by controlling the orientation of the applied field relative to the film plane. Micromagnetic simulations accurately reproduce our FMRFM spectra allowing quantitative understanding of the localized modes. Our results reveal a general method of generating tightly confined spin wave modes in various geometries with excellent spatial resolution that significantly facilitates the broad application of FMRFM. This paves the way to imaging of magnetic properties and spin wave dynamics in a variety of contexts for uncovering new physics of nanoscale spin excitations.

IKK promotes cytokine-induced and cancer-associated AMPK activity and attenuates phenformin-induced cell death in LKB1-deficient cells

description: The 5′ AMP-activated protein kinase (AMPK) is an energy sensor that is activated upon phosphorylation of Thr172 in its activation loop by the kinase LKB1, CAMKK2, or TAK1. TAK1-dependent AMPK phosphorylation of Thr172 is less well characterized than phosphorylation of this site by LKB1 or CAMKK2. An important target of TAK1 is IB kinase (IKK), which controls the activation of the transcription factor NF-B. We tested the hypothesis that IKK acted downstream of TAK1 to activate AMPK by phosphorylating Thr172. IKK was required for the phosphorylation of Thr172 in AMPK in response to treatment with the inflammatory cytokine IL-1 or TNF- or upon TAK1 overexpression. In addition, IKK regulated basal AMPK Thr172 phosphorylation in several cancer cell types independently of TAK1, indicating that other modes of IKK activation could stimulate AMPK. We found that IKK directly phosphorylated AMPK at Thr172 independently of the tumor suppressor LKB1 or energy stress. Accordingly, in LKB1-deficient cells, IKK inhibition reduced AMPK Thr172 phosphorylation in response to the mitochondrial inhibitor phenformin. This response led to enhanced apoptosis and suggests that IKK inhibition in combination with phenformin could be used clinically to treat patients with LKB1-deficient cancers.

description: Thioridazine is an antipsychotic that has been shown to induce cell death and inhibit self-renewal in a broad spectrum of cancer cells. The mechanisms by which these effects are mediated are currently unknown but are presumed to result from the inhibition of dopamine receptor 2 (DRD2). Here we show that the self-renewal of several, but not all, triple-negative breast cancer cell lines is inhibited by thioridazine. The inhibition of self-renewal by thioridazine in these cells is mediated by DRD2 inhibition. Further, we demonstrate that DRD2 promotes self-renewal in these cells via a STAT3- and IL-6 – dependent mechanism. We also show that thioridazine induces a G1 arrest and a loss in cell viability in all tested cell lines. However, the reduction in proliferation and cell viability is independent of DRD2 and STAT3. Our results indicate that although there are cell types in which DRD2 inhibition results in inhibition of STAT3 and self-renewal, the dramatic block in cancer cell proliferation across many cell lines caused by thioridazine treatment is independent of DRD2 inhibition.
Revisiting the quantum decoherence scenario as an explanation for the LSND anomaly

description: We propose an explanation for the LSND anomaly based on quantum decoherence, postulating an exponential behavior for the decoherence parameters as a function of the neutrino energy. Within this ansatz decoherence effects are suppressed for neutrino energies above 200 MeV as well as around and below few MeV, restricting deviations from standard three-flavour oscillations only to the LSND energy range of 20--50 MeV. The scenario is consistent with the global data on neutrino oscillations, alleviates the tension between LSND and KARMEN, and predicts a null-result for MiniBooNE. No sterile neutrinos are introduced, conflict with cosmology is avoided, and no tension between short-baseline appearance and disappearance data arises. The proposal can be tested at planned reactor experiments with baselines of around 50 km, such as JUNO or RENO-50.

Entropy Production in Relativistic Jet Boundary Layers

description: Hot relativistic jets, passing through a background medium with a pressure gradient p \propto r^{-η} where 2 < η<= 8/3, develop a shocked boundary layer containing a significant fraction of the jet power. In previous work, we developed a self-similar description of the boundary layer assuming isentropic flow, but we found that such models respect global energy conservation only for the special case η= 8/3. Here we demonstrate that models with η< 8/3 can be made self-consistent if we relax the assumption of constant specific entropy. Instead, the entropy must increase with increasing r along the boundary layer, presumably due to multiple shocks driven into the flow as it gradually collimates. The increase in specific entropy slows the acceleration rate of the flow and provides a source of internal energy that could be channeled into radiation. We suggest that this process may be important for determining the radiative characteristics of tidal disruption events and gamma-ray bursts from collapsars.

description: Idiopathic pneumonia syndrome (IPS) is a noninfectious inflammatory disorder of the lungs that occurs most often after fully myeloablative allogeneic hematopoietic stem cell transplantation (HSCT). IPS can be severe and is associated with high 1-year mortality rates despite existing therapies. The canonical nuclear factor-(NF) κB signaling pathway has previously been linked to several inflammatory disorders of the lung, including asthma and lung allograft rejection. It has never been specifically targeted as a novel IPS treatment approach, however. Here, we report that the IκB kinase 2 (IKK2) antagonist BAY 65-5811 or “compound A,” a highly potent and specific inhibitor of the NF-κB pathway, was able to improve median survival times and recipient oxygenation in a well-described mouse model of IPS. Compound A impaired the production of the proinflammatory chemokines CCL2 and CCL5 within the host lung after transplantation. This resulted in significantly lower numbers of donor lung infiltrating CD4+ and CD8+ T cells and reduced pulmonary inflammatory cytokine production after allograft. Compound A's beneficial effects appeared to be specific for limiting pulmonary injury, as the drug was unable to improve outcomes in a B6 into B6D2 haplotype-matched murine HSCT model in which recipient mice succumb to lethal acute graft-versus-host disease of the gastrointestinal tract. Collectively, our data suggest that the targeting of the canonical NF-κB pathway with a small molecule IKK2 antagonist may represent an effective and novel therapy for the specific management of acute lung injury that can occur after allogeneic HSCT.

description: Signal transducer and activator of transcription 3 (STAT3) mediates cellular responses to multiple cytokines, governs gene expression, and regulates the development and activation of immune cells. STAT3 also modulates reactivation of latent herpes simplex virus-1 (HSV-1) in ganglia. However, it is unclear how STAT3 regulates the innate immune response during the early phase of HSV-1 lytic infection. Many cell types critical for the innate immunity are derived from the myeloid lineage. Therefore, in this study, we used myeloid-specific Stat3 knockout mice to investigate the role of STAT3 in the innate immune response against HSV-1. Our results demonstrate that Stat3 knockout bone marrow-derived macrophages (BMMs) expressed decreased levels of interferon-α (IFN-α) and interferon-stimulated genes (ISGs) upon HSV-1 infection. In vivo, knockout mice were more susceptible to HSV-1, as marked by higher viral loads and more significant weight loss. Splenic expression of IFN-α and ISGs was reduced in the absence of STAT3, indicating that STAT3 is required for optimal type I interferon response to HSV-1. Expression of TNF-α and IL-12, cytokines that have been shown to limit HSV-1 replication and pathogenesis, was also significantly lower in knockout mice. Interestingly, Stat3 knockout mice failed to expand the CD8+ conventional DC (cDC) population upon HSV-1 infection, and this was accompanied by impaired NK and CD8 T cell activation. Collectively, our data demonstrate that myeloid-specific Stat3 deletion causes defects in multiple aspects of the immune system and that STAT3 has a protective role at the early stage of systemic HSV-1 infection.

Исследования выполнялись на пойменных территориях в окрестностях д. Юган Сургутского района ХМАО-Югры и на мониторинговом участке Усть-Балыкского месторождения, где проводился сбор растительных образцов для определения содержания пигментов фотосинтеза. В качестве объектов для исследования были выбраны Calamagrostis purpurea Trin., Carex acuta L., Carex aquatilis Wahlenb., Carex vesicaria L., Carex rostratа Stokes., Elytrigia repens Nevski, Phalaroides arundinacea Rausch. Сырье отбиралось методом конверта в пяти повторностях. Работы проводились на сухом материале. Определение фотосинтетических пигментов проводилось на спектрофотометре СФ-56 (компании «ЛОМО-СПЕКТР») спектрофотометрическим методом. Оптическую плотность в растительных вытяжках определяли при следующих длинах волн: хлорофилл a — 665 нм, хлорофилл b — 649 нм, каротиноиды — 470 нм. Содержание хлорофиллов и каротиноидов у растений, взятых на глинисто-песчаной отсыпке Усть-Балыкского участка, по сравнению с содержанием фотосинтетических пигментов растений из окрестностей д. Юган, низкое, что свидетельствует об их угнетенном состоянии, вызванном нефтяным загрязнением.

description: We present a parameterization of the statistical rate function, f, for 20 superallowed 0+-to-0+ nuclear beta transitions between T=1 analog states, and for 18 superallowed "mirror" transitions between analog T=1/2 states. All these transitions are of interest in the determination of V_{ud}. Although most of the transition Q_{EC} values have been measured, their precision will undoubtedly be improved in future. Our parameterization allows a user to easily calculate the corresponding new f value to high precision (+/-0.01%) without complicated computing.

description: В условиях вегетационного эксперимента показана эффективность метода сорбционной биоремедиации почв Кольского п-ва, исторически загрязненных горюче-смазочными материалами при исходном уровне суммарного содержания углеводородов нефти (УВН) 25,3 г/кг. При биоремедиации почвы путем активации аборигенных микроорганизмов-нефтедеструкторов за счет оптимизации аэрогидротермического режима, а также известкования и подкормки минеральными удобрениями внесение 1 или 3 % ГАУ позволило снизить содержание УВН на 78 и 91 % за 4 месяца соответственно, тогда как в почве без добавок их концентрация снизилась лишь на 55 %. Резкое увеличение дегидрогеназной активности почвы в присутствии ГАУ (в 29—70 раз по сравнению с контрольными вариантами) свидетельствует о значительном повышении активности углеводородокисляющих микроорганизмов. Кроме того, внесение ГАУ снизило степень подкисления почвы и обеспечило существенное снижение ее фитотоксичности (оценка по длине корней проростков овса) на 38—75 % по сравнению с контролем с внесением одних минеральных удобрений и известкования. Положительное действие сорбента, по-видимому, можно объяснить снижением токсичности почвы за счет обратимой сорбции поллютанта и частично за счет нейтрализации повышенной кислотности почвы.

description: Исследована взаимосвязь показателей здоровья населения, проживающего в условиях Среднего Приобья в г. Сургуте, на примере случаев обращений жителей по заболеваниям системы органов дыхания и анализа степени загрязнения атмосферного воздуха. Состояние качества атмосферы оценивали по уровню содержания наиболее значимых химических поллютантов (в долях предельно допустимой концентрации) и комплексного индекса загрязнения атмосферы (КИЗА) в динамике 2010—2014 гг. Установлено, что к приоритетным загрязнителям относятся формальдегид, 3,4-бенз(α)пирен, фенол, диоксид азота и взвешенные частицы, а максимальное значение КИЗА отмечено в 2012 г. Влияние аэрогенных поллютантов на организм человека оценивалось с применением метода расчета канцерогенного и неканцерогенного риска. Уровень суммарного неканцерогенного риска, обусловленного загрязнением атмосферного воздуха, с учетом рассчитанных коэффициентов опасности (HQ) и суммарного индекса характеризовался величиной 8,27. Величина суммарного уровня хронического канцерогенного риска составляла 6,0•10–5, т.е. уровень опасности для атмосферного воздуха квалифицировался как приемлемый уровень риска, но требующий постоянного наблюдения за содержанием данных веществ. Анализ случаев обращений жителей г. Сургута в медицинские учреждения по поводу болезней органов дыхания на фоне уровня загрязнения атмосферного воздуха аэрогенными веществами, демонстрировал прямую связь с содержанием данных ингредиентов (суммарно, по значению КИЗА), и эта взаимосвязанность с применением критерия ранговой корреляции Спирмена характеризовалась значением коэффициента заметной силы (Rs = 0,60, при р <0,05).

description: В статье приводится анализ данных о влиянии йода в различных концентрациях на энергию прорастания, всхожесть семян, длину ростка, корней зерновых культур, также проанализировано сравнительное действие иодида и хлорида калия на начальные показатели роста и развития яровой пшеницы. Рассмотрены математические модели зависимости влияния микроудобрений на показатели роста и всхожесть семян пшеницы от дозы поступления хлорида и йодида калия. Полученные данные позволили выявить оптимальные концентрации йода для обогащения этим микроэлементом зерновых культур. В целом по всем изучаемым показателям установлено, что оптимальные концентрации йода для зерновых культур находятся в диапазоне 0,005—0,02 %. Результаты проведенных исследований могут быть использованы при разработке практических рекомендаций по возделыванию сельскохозяйственных культур в условиях йододефицита.

description: В период с 2017 по 2019 г. было обследовано 48 водных объектов на территории г. Рязани, Спасского, Клепиковского, Сасовского районов Рязанской области. Выявлено три вида моллюсков семейства Bithyniidae: Codiella leachi (Sheppard, 1823), Bithynia tentaculata (Linnaeus, 1758) и B. Product (Moquin-Tandon, 1855). Из них только два первых вида рассматриваются как первые промежуточные хозяева O. felineus. Наибольшее количество гастропод отмечено в биотопах с хорошо развитыми макрофитами: C. leachi в литоральной зоне озер (70 %), B. tentaculata — в рипали рек (41,9 %), в старицах и затонах рек (23,0 %). Наибольшая численность и биомасса C. Leachi были на грунтах с участием ила: глинисто-илистом (123 экз./м2, 11,6 г/м2), песчаноилистом (100 экз./м2, 6,4 г/м2). Для B. Tentaculata оказались благоприятными условия на донных отложениях из глины и песка (82 экз./м2, 7,8 г/м2). C. leachi и B. tentaculata обитают в водоемах и водотоках разного трофического статуса, при снижении трофности в составе макрозообентоса увеличивается доля битиниид. В условиях ультроолиготрофного водного объекта основную часть по численности и биомассе в бентосе составляют B. tentaculata. Наиболее благоприятные условия для C. leachi и B. Tentaculata находятся в α-мезосапробной зоне.

description: Ritenuta la più coerente conclusione di un processo diretto alla salvaguardia dei diritti umani all’interno dell’Unione europea, la disposizione del TUE che prescrive l’adesione dell’Unione alla Convenzione europea dei diritti dell’uomo (CEDU) non ha ancora trovato attuazione, ancorché i negoziati siano iniziati nel 2010. In realtà, nell’Aprile del 2013 un parziale risultato è stato conseguito, pel tramite della presentazione di un progetto di accordo di adesione da parte di un gruppo ad hoc di rappresentanti degli Stati membri del Consiglio d’Europa e della Commissione dell’Unione europea.
All’esito di un breve rendiconto dei precedenti storici concernenti l’adesione, il presente contributo esamina il contenuto della proposta di accordo e le principali questioni giuridiche connesse, tratteggiando possibili sviluppi futuri.

description: Проведено изучение цитогенетических характеристик семенного потомства деревьев интродуцента — ореха грецкого (Juglans regia L.), длительное время произрастающих на территории Воронежской области. Показано преимущественно стабильное протекание митоза в клетках корневой меристемы проростков. Отмечается средний уровень митотической активности (5,8 ± 0,4 % и 3,8 ± 0,3 %, с учетом и без учета профазных клеток соответственно), низкий уровень патологий (6,0 ± 0,8 %) и остаточных ядрышек в митозе (0,6 ± 0,2 %). Представлены микрофотографии некоторых видов функциональных и структурных нарушений клеточного деления. Приводится описание и фотографии ядрышек, наблюдавшихся в интерфазных клетках проростков семенного потомства ореха грецкого. Отмечается значительная функциональная активность ядрышкового аппарата с преимущественным преобладанием в спектре высокоактивных типов ядрышек — «кора-сердцевина» (66,7 ± 3,0 %) и компактных (3,0 ± 1,2 %). Умеренноактивные ядрышки типа «кора-сердцевина» с вакуолью встречались с частотой 30,2 ± 3,0 %, а их пониженная активность компенсируется увеличением площади их поверхности. Делается вывод о хорошей адаптации материнских растений к условиям произрастания в Воронежской области и возможности рекомендовать их семенное потомство для отбора форм ореха грецкого с лучшими для данных экологических условий качествами.

description: Sage (Salvia officinalis L.) is cultivated worldwide for its aromatic leaves which are used as herbal spice and for phytopharmaceutical applications. Fast analytical strategies for essential oil analysis, performed directly on plant material would reduce the delay between sampling and analytical results. This would enhance product quality by improving technical control of cultivation. The attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy method described here provides a reliable calibration model for quantification of essential oil components (EOC) and its main constituents (e.g. -thujone and -thujone) directly on dried, intact leaves of sage. Except for drying no further sample preparation is required for ATR-FTIR and the measurement time of less than 5 min per sample contrasts with the most common alternative of hydro-distillation followed by GC analysis which can take several hours per sample.

description: Основными источниками азотного питания растений служат соли аммония и азотной кислоты (нитраты). Недостаток азота приводит к слабому кущению, уменьшению листовой поверхности, снижению числа и массы зерен в колосе [1]. Причиной нарушения ассимиляции нитратов в растениях могут выступают различные факторы: сроки, формы, дозы внесения удобрения, метеорология, видовые и сортовые особенности растений, предшественники. Именно неэффективное использование средств химизации, нарушение существующих регламентов служат источником наблюдаемых отрицательных последствий. В статье приведены закономерности в распределении нитратных и аммиачных форм азота по профилю почвы (0—100 см) в течение вегетационного периода формирования урожая озимой пшеницы. В этой связи приведены численные показатели минерального и аммиачного азота в почве по годам исследований и фенологическим фазам развития эдификатора с учетом предшественника. Максимальная урожайность зерна озимой пшеницы 53,0 ц/га зафиксирована на ключевом участке с предшественником люпином однолетним; минимальная (33,5 ц/га) — на участке с предшественником картофелем столовым. Наиболее высокая потребность растений озимой пшеницы приходится в фазу конец кущения — начало выхода в трубку.
