Local Heat Transfer In Turbine Disk-Cavities

displayed. The significant magnitude of stator heat transfer in many cases indicates the importance of proper stator modeling to rotor and disk-cavity heat transfer results. Results are presented from an experimental study designed to obtain detailed radial heat transfer coefficient distributions applicable to the cooling of diskcavity regions of gas turbines. An experimental apparatus has been designed to obtain local heat transfer data on both the rotating and stationary surfaces of a parallel geometry disk-cavity system. The method employed utilizes thin thermochromic liquid crystal coatings together with video system data acquisition and computer-assisted image analysis to extract heat transfer information. The color display of the liquid crystal coatings is detected through the analysis of standard video chromanance signals. The experimental technique used is an aerodynamically steady but thermally transient one which provides consistent disk-cavity thermal boundary conditions while yet being inexpensive and highly versatile. A single circular jet is used to introduce fluid from the stator into the disk-cavity by impingement normal to the rotor surface. The present study investigates hub injection of coolant over a wide range of parameters including disk rotational Reynolds numbers of 2 to 5 • 10 5 , rotor/stator spacing-to-disk radius ratios of . 025 to . 15, and jet mass flow rates between . 10 and . 40 times the turbulent pumped flow rate of a free disk. The results are presented as radial distributions of local Nusselt numbers. Rotor heat transfer exhibits regions of impingement and rotational domination with a transition region between, while stator heat transfer shows flow reattachment and convection regions with evidence of an inner recirculation zone. The local effects of rotation, spacing, and mass flow rate are all Nomenclature A heat transfer area
Analyzing the students' learning behaviour for a technical course Analyzing the students' learning behaviour for a technical course during COVID-19 during COVID-19

-The purpose of this paper is to analyse the learning behaviour of students towards a technical course in the two learning modes, remote learning (online) and in-person learning (offline). Due to the outbreak of Covid-19 pandemic in India, the educational fraternity has successfully reached out to the students using the various virtual tools available. Although, the offline mode of teaching-learning i.e. the actual classroom interaction is quite important as far as a technical course is concerned, but during these tough times the online platforms like Zoom, Webex meetings, Google meet have made the teaching-learning feasible remotely at any time from any place. This paper compares the learning behaviour of students in the two modes, emergency virtual mode and offline mode. A total of 213 Bachelors of Engineering (BE) students studying a technical course, Modern and Computational Physics, participated in the survey and their responses based on a questionnaire were recorded. The questionnaire considered all aspects related to the delivery of contents, the evaluation method, the preferred way of clarifying students’ doubts, course difficulty level and duration of the course. The analysis suggests that 72.3% of students are in favour of learning this course using offline mode, while 27.7 % of students are comfortable with virtual online mode. Furthermore, the present study reveals that 95.7%, 95.3%, and 75.1 % of students are congenial with the offline mode in terms of teacher competency, content delivery, and interaction possibility respectively, whereas 85%, 76.9% and 48.4% of students are congenial with the remote online mode in terms of same parameters. The higher magnitude of average mean value for offline mode (3.99) anticipates its dominance over online mode (3.18). More than 50% students favoured online mode along with multiple choice question papers for the evaluation process irrespective of their preference to offline mode for teaching-learning. Based on the present analysis, some recommendations are proposed as the future strategies to improve the performance of teaching-learning activities during the times of crisis.
DOES THE WAY WE MEMORIZE INFORMATION DEPEND ON THE WAY WE ARE GOING TO USE IT?

The study of parent-child representations across cultures is important in order to obtain a proper understanding of the attributes, size and positioning of such figures as indicators of different interaction patterns across cultures. A thorough base of research evidence for the interpretation of children’s drawings may facilitate work in multicultural educational settings and enhance our understanding of cultural diversity in schools. Italy provides an ideal context for the study of parent-child representations, as the country has witnessed increasing cultural diversity in recent years with the immigration of various ethnic groups. This study examined the extent to which this context influences children’s representations in domains of Cohesion (interpersonal bonding), Similarity (affinity) and Value (spatial relevance) among parent-child figures because these domains inform important representational processes of interpersonal bonding with parents across specific cultures. The Pictorial Assessment of Interpersonal Relationships (PAIR) was used to codify drawings of 326 children with Albanian (n = 59), Serbian (n = 85) and Italian (n = 182) backgrounds. The results showed that in drawings made by Albanian and Serbian children parental figures were drawn similar to and close to the child figure representing their less independent reciprocal stance. The parental figures drawn by Italian children appear bigger and farther apart. Important implications may be derived from the results in facilitating work in multicultural educational settings, by enhancing knowledge regarding cultural diversity in schools.
CONSUMPTION DIETARY SOURCES OF LYCOPENE, LUTEIN, AND ZEAXANTHIN AMONG YOUNG ADULTS LIVING IN MOSCOW

Carotenoids are natural antioxidants, affecting apoptosis, absorbing active forms of oxygen, and improving visual performance through their blue light filtering capabilities. Lutein and zeaxanthin are carotenoids of the macular pigment that play a significant role in protecting against age-related macular degeneration (AMD), cataracts, and diabetic retinopathy. We analyzed the dietary sources of lycopene, lutein, and zeaxanthin of young adults living in a megapolis. We analyzed 431 food frequency questionnaires and used two different criteria for comparison: age (groups A1 and A2) and season (groups S1, spring, and S2, autumn). Raw red tomatoes and eggs are the main sources of carotenoids for the majority of respondents regardless of age and season. Significant differences between age groups were found for parsley, carrot, cheeseburger, and spring onion. Foods with high levels of carotenoids (tomato juice, pumpkin, spinach, and sprouts) were absent in the diets of most of the study participants. Watermelons and persimmons are seasonal sources of lycopene, lutein, and zeaxanthin. Dietary sources of carotenoids are present in insufficient quantities in the diets. Foods with high levels of lycopene, lutein, and zeaxanthin are absent or only occasionally included in the diet.

Tourism 2021 04EN 465-636.indd

Th is study examines whether Portuguese hotel sector fi rms engage in earnings management (EM) practices to provide specifi c accounting results and test the main determinants in explaining EM. We use the SABI database to collect panel data regarding 1615 Portuguese SME hotels from 2006–2013. In order to obtain results, a graphical representation of the distribution of the net income and the estimation of the discretionary accruals were used, from which two estimation models were formulated. Th e results obtained provide empirical evidence that fi rms in the Portuguese hotel sector seem to engage in earnings management practices and that the main determinants behind them appear to be debt level, return on assets, and fi rm size. Th e adoption of earnings management practices by fi rms is a widespread phenomenon across various sectors and nations. Yet, despite the general awareness regarding the importance of the tourism sector for communities at a fi nancial, social, and cultural level, the lack of empirical studies with application to the accommodation sector makes it pertinent to investigate this phenomenon.
Forest±atmosphere carbon dioxide exchange in eastern Siberia

We investigated the daily exchange of CO2 between undisturbed Larix gmelinii (Rupr.) Rupr. forest and the atmosphere at a remote Siberian site during July and August of 1993. Our goal was to measure and partition total CO2 exchanges into aboveground and belowground components by measuring forest and understory eddy and storage ̄uxes and then to determine the relationships between the environmental factors and these observations of ecosystem metabolism. Maximum net CO2 uptake of the forest ecosystem was extremely low compared to the forests elsewhere, reaching a peak of only 5 mmol mÿ2 sÿ1 late in the morning. Net ecosystem CO2 uptake increased with increasing photosynthetically active photon ̄ux density (PPFD) and decreased as the atmospheric water vapor saturation de®cit (D) increased. Daytime ecosystem CO2 uptake increased immediately after rain and declined sharply after about six days of drought. Ecosystem respiration at night averaged 2.4 mmol mÿ2 sÿ1 with about 40% of this coming from the forest ̄oor (roots and heterotrophs). The relationship between the understory eddy ̄ux and soil temperature at 5 cm followed an Arrhenius model, increasing exponentially with temperature (Q10 2.3) so that on hot summer afternoons the ecosystem became a source of CO2. Tree canopy CO2 exchange was calculated as the difference between above and below canopy eddy ̄ux. Canopy uptake saturated at 6 mmol CO2 m ÿ2 sÿ1 for a PPFD above 500 mmol mÿ2 sÿ1 and decreased with increasing D. The optimal stomatal control model of MaÈkelaÈ et al. (1996) was used as a `big leaf' canopy model with parameter values determined by the non-linear least squares. The model accurately simulated the response of the forest to light, saturation de®cit and drought. The precision of the model was such that the daily pattern of residuals between modeled and measured forest exchange reproduced the component storage ̄ux. The model and independent leaf-level measurements suggest that the marginal water cost of plant C gain in Larix gmelinii is more similar to values from deciduous or desert species than other boreal forests. During the middle of the summer, the L. gmelinii forest ecosystem is generally a net sink for CO2, storing 0.75 g C mÿ2 dÿ1. Published by Elsevier Science B.V.
Rational Equivariant Spectra

We develop model categories of rational equivariant spectra whose homotopy categories are equivalent to the category of rational equivariant cohomology theories. We prove that given an orthogonal decomposition of the unit in the rational Burnside ring, the model category of rational equivariant spectra decomposes into a product of localisations. We use this result to reprove the classification of rational equivariant cohomology theories for finite groups and to study such cohomology theories for the group O(2). We then concentrate on a split piece of the O(2) case and relate it to rational SO(2) equivariant spectra.
Combined Modality Therapy with Bleomycin, Hyperthermia, and Radiation1

In an attempt to develop better combination therapies for use with local radiation, the interaction between bleomycin and hyperthermia Â± radiation was studied in the FSallC tumor system. In cells exposed in vitro to bleomycin at 37Â°Cand at pH 7.40, the drug was substantially more toxic toward normally oxygenated than hypoxic cells. At hyperthermic temperatures (42Â°or 43Â°C),however, the differential killing between the normally oxygenated and hypoxic cells disappeared and bleomycin became significantly more toxic. Exposure to bleomycin at pH 6.45 did not substantially alter the cytotoxicity of the drug at 42Â°or 43Â°C. In tumor growth delay experiments, combining bleomycin, hyper thermia, and radiation induced long delays, and the more successful sequences were bleomycinâ€”Â»radiationâ€”Â»hyperthermia or bleomycinâ€”Â»hy perthermiaâ€”Â»radiation. If radiation was given prior to drug and hyper thermia, however, the sequence was significantly less effective. In tumor excision experiments performed 24 h after treatment, increasing doses of bleomycin produced a shallow, log-linear increase in tumor cell kill at 37Â°C,but bleomycin followed by hyperthermia (43Â°C,30 min) led to about 1 log more cell killing. Administration of bleomycin just prior to treatment with a single dose of radiation was cytotoxically additive. In this assay the most effective trimodality treatment sequence was bleo mycinâ€”Â»hyperthermiaâ€”Â»radiation. In tumor subpopulations defined by Hoechst 33342 dye staining, bleomycin at 37Â°Cwas about two-fold more toxic toward the bright (presumably well-oxygenated) cells than toward the dim (presumably hypoxic) cell subpopulation. The addition of hyperthermia following bleomycin produced nearly a log more tumor cell killing in both the bright and dim tumor cells. The combination of bleomycin followed by hyperthermia and then radiation was at least additive in the bright cells and caused a large cell kill, but, in comparison, there was marked sparing of the dim cells. These results indicate that treatment with bleomycin and hyperthermia in conjunction with radiation can add substantially to tumor cell killing. This combination is significantly less effective in the hypoxic than oxic tumor regions, however, in spite of in vitro data which demonstrate that the cytotoxicity of bleomycin at hyperthermic temper atures is not oxygen-dependent.
INFORMATIVE NOTE: An opinion on the regulation of bone marrow adipose tissue by dietary fatty acids ; NOTA INFORMATIVA: Una opinión sobre la regulación del tejido adiposo de médula ósea por los ácidos grasos de la dieta

Obesity has a significant impact on predisposition to various diseases and also affects the viability and choice of haematopoietic stem cells (HSCs) to favour myeloid cell production and/or turnover, all of which are extremely important for the functioning of immune system. As the production of blood cells and mobilization of HSCs and their progeny are regulated, at least in part, by multifaceted interactions through signals that come from the bone marrow (BM) microenvironment, it does not seem astonishing to assume that circumstances that cause alterations in BM structure will unavoidably cause alterations in mesenchymal cells such as adipocytes and lineages from HSCs. The existence of adipose tissue in BM or marrow fat (BMAT) is well known, although its origin, expansion, and functions are poorly understood. Inspired by other studies showing the potential role for olive oil and omega-3 long chain polyunsaturated fatty acids (omega-3 PUFAs) on BM health, and by our own preliminary findings showing the effects of monounsaturated (olive oil) but not saturated (milk cream) dietary fats to contain neutrophils and CD14 monocytes in BM during postprandial periods in healthy volunteers, herein we asked whether dietary fats (saturated fatty acids, SFAs, monounsaturated fatty acids, MUFAs, and omega-3 PUFAs) may be a candidate lifestyle factor to modulate the expansion, composition, and function of BMAT, the infiltration of adipose tissue macrophages (ATMs) in BMAT and the mobilization of HSCs and mature myeloid cells from BM during high-fat-induced obesity in mice. This is the first time that the interplay between different dietary fatty acids, obesity, and BM is addressed.
Coarse-grained Theory and Simulation of Assemblies of Intrinsically-disordered Nucleoporins by Chad

Coarse-grained Theory and Simulation of Assemblies of Intrinsically-disordered Nucleoporins Chad Gu Doctor of Philosophy Graduate Department of Physics University of Toronto 2019 Selective import and export through the nuclear envelope in the eukaryotic cell is solely regulated by the transporter known as Nuclear Pore Complex (NPC). The transport conduit of the NPC is occupied by intrinsically-disordered nuclear pore proteins collectively known as FG nucleoporins, which confer selectivity to the pore, hindering the passage of large, neutral molecules while facilitating the translocation of cargos recognized by carriers known as transport proteins. Currently, the mechanism of selectivity and permeability behaviour of the NPC is a subject of intense research, though much of our understanding of the NPC is based on inferences from experiments on in vitro assemblies of FG nucleoporins, requiring rigorous analysis through a theoretical framework. In this thesis, employing approaches based on mean field theory and numerical simulations, I investigate the behaviours of in vitro assemblies of FG nucleoporins under conditions commonly studied in experiments. The models studied in this thesis depend on the most important interaction and geometric parameters of the system, but are capable of providing semi-quantitative descriptions of experimental results. In addition, these models provide the means to characterize the effective interactions between the FG nucleoporin assemblies and transport proteins, and translate equilibrium measurements of these interactions into the dynamics of transport. In all types of FG nucleoporin assemblies, different entropic and enthalpic effects stemming from molecular interactions determine the affinity between FG nucleoporin and transport proteins, demonstrating the physics of the in vitro assemblies that are expected to arise in the NPC.
Prostaglandin Endoperoxide H Synthase-1 THE FUNCTIONS OF CYCLOOXYGENASE ACTIVE SITE RESIDUES IN THE BINDING, POSITIONING, AND OXYGENATION OF ARACHIDONIC ACID* h S

Prostaglandin endoperoxide H synthases (PGHSs) catalyze the committed step in the biosynthesis of prostaglandins and thromboxane, the conversion of arachidonic acid, two molecules of O 2 , and two electrons to prostaglandin endoperoxide H 2 (PGH 2 ). Formation of PGH 2 involves an initial oxygenation of arachidonate to yield PGG 2 catalyzed by the cyclooxygenase activity of the enzyme and then a reduction of the 15-hydroperoxyl group of PGG 2 to form PGH 2 catalyzed by the peroxidase activity. The cyclooxygenase active site is a hydrophobic channel that protrudes from the membrane binding domain into the core of the globular domain of PGHS. In the crystal structure of Co 3 1 -heme ovine PGHS-1 complexed with arachidonic acid, 19 cyclooxygenase active site residues are predicted to make a total of 50 contacts with the substrate (Malkowski, M. G, Ginell, S., Smith, W. L., and Garavito, R. M. (2000) Science 289, 1933–1937); two of these are hydrophilic, and 48 involve hydrophobic interactions. We performed mutational analyses to determine the roles of 14 of these residues and 4 other closely neighboring
The B1 Subunit of the HATPase Is a PDZ Domain-binding Protein COLOCALIZATION WITH NHE-RF IN RENAL B-INTERCALATED CELLS*

The 56-kDa B1 subunit of the vacuolar HATPase has a C-terminal DTAL amino acid motif typical of PDZbinding proteins that associate with the PDZ protein, NHE-RF (Na/H exchanger regulatory factor). This B1 isoform is amplified in renal intercalated cells, which play a role in distal urinary acid-base transport. In contrast, proximal tubules express the B2 isoform that lacks the C-terminal PDZ-binding motif. Both the B1 56-kDa subunit and the 31-kDa (E) subunit of the HATPase are pulled down by glutathione S-transferase NHE-RF bound to GSH-Sepharose beads. These subunits associate in vivo as part of the cytoplasmic V1 portion of the HATPase, and the E subunit was co-immunoprecipitated from rat kidney cytosol with NHE-RF antibodies. The interaction of HATPase subunits with NHE-RF was inhibited by a peptide derived from the C terminus of the B1 but not the B2 isoform. NHE-RF colocalized with HATPase in either the apical or the basolateral region of B-type intercalated cells, whereas NHE-RF staining was undetectable in A-intercalated cells. In proximal tubules, NHE-RF was located in the apical brush border. In contrast, HATPase was concentrated in a distinct membrane domain at the base of the brush border, from which NHE-RF was absent, consistent with the expression of the truncated B2 subunit isoform in this tubule segment. The colocalization of NHE-RF and HATPase in Bbut not A-intercalated cells suggests a role in generating, maintaining, or modulating the variable HATPase polarity that characterizes the B-cell phenotype.
Free resolutions via Gröbner bases

For associative algebras in many different categories, it is possible to develop the machinery of Gr\"obner bases. A Gr\"obner basis of defining relations for an algebra of such a category provides a "monomial replacement" of this algebra. The main goal of this article is to demonstrate how this machinery can be used for the purposes of homological algebra. More precisely, our approach goes in three steps. First, we define a combinatorial resolution for the monomial replacement of an object. Second, we extract from those resolutions explicit representatives for homological classes. Finally, we explain how to "deform" the differential to handle the general case. For associative algebras, we recover a well known construction due to Anick. The other case we discuss in detail is that of operads, where we discover resolutions that haven't been known previously. We present various applications, including a proofs of Hoffbeck's PBW criterion, a proof of Koszulness for a class of operads coming from commutative algebras, and a homology computation for the operads of Batalin--Vilkovisky algebras and of Rota--Baxter algebras.
Tıp Fakültesi Öğrencilerinin Olumsuz Değerlendirilme Korku Düzeyleri, Akademik Erteleme Davranışları, Akademik Başarılarının İncelenmesi1

Fear of negative evaluation and academic procrastination behaviours have the potential to negatively affect individuals both academically and psychologically. This study aims to analyze the medical students’ level of fear of negative evaluation, academic procrastination and academic achievement according to several variables. Data were collected from 774 students studying at Çanakkale Onsekiz Mart University Faculty of Medicine in the spring semester of the 2019-2020 academic year. To collect data, Tuckman Academic Procrastination Scale and Fear of Negative Evaluation Scale were used. Academic achievement grade point averages were taken from student affairs office; a four-category question was asked about the level of test anxiety the students experienced. MANOVA and regression analysis were used to analyze the data. The results showed that the medical students' level of academic procrastination and fear of negative evaluation was moderate, and there was no significant difference in academic success, academic procrastination and fear of negative evaluation by gender. The interaction between gender and test anxiety did not make a significant difference in academic achievement, academic procrastination and fear of negative evaluation; however, it was determined that the test anxiety created a significant difference in academic achievement, academic procrastination and fear of negative evaluation.
