Abstract:
OBJECTIVE Stereotactic laser ablation (SLA) is typically performed in the setting of intraoperative MRI or in a staged manner in which probe insertion is performed in the operating room and thermal ablation takes place in an MRI suite. METHODS The authors describe their experience, in which SLA for glioblastoma (GBM) treatment was performed entirely within a conventional MRI suite using the SmartFrame stereotactic device. RESULTS All 10 patients with GBM (2 with isocitrate dehydrogenase 1 mutation [mIDH1] and 8 with wild-type IDH1 [wtIDH1]) were followed for > 6 months. One of these patients underwent 2 independent SLAs approximately 12 months apart. Biopsies were performed prior to SLA for all patients. There were no perioperative morbidities, wound infections, or unplanned 30-day readmissions. The average time for a 3-trajectory SLA (n = 3) was 436 ± 102 minutes; for a 2-trajectory SLA (n = 4) was 321 ± 85 minutes; and for a single-trajectory SLA (n = 4) was 254 ± 28 minutes. No tumor recurrence occurred within the blue isotherm line ablation zone, although 2 patients experienced recurrence immediately adjacent to the blue isotherm ablation line. Overall survival for the patient cohort averaged 356 days, with the 2 patients who had mIDH1 GBMs exhibiting the longest survival (811 and 654 days). CONCLUSIONS Multitrajectory SLA for treatment of GBM can be safely performed using the SmartFrame stereotactic device in a conventional MRI suite.

Abstract:
Growth analyses were carried out on young plants of 15 genotypes, grown initially at 19/14 degrees C day/night temperatures for an 8 h day at low light intensity and subsequently at the night temperatures of 6, 10 and 14 degrees C. Significant genotypic differences occurred for relative growth rate (RGR), net assimilation rate (NAR), leaf area ratio (LAR), specific leaf area (SLA) and leaf weight ratio (LWR). RGR, LAR and SLA increased and LWR decreased at higher night temperatures. A strong negative correlation was observed between NAR and LAR and NAR and SLA whilst a positive correlation was noted between LAR and SLA. Plant weight was strongly influenced by seed size.

Abstract:
Owing to the excellent bioactive properties of recombinant human bone morphogenetic proteins (rhBMPs), dentistry considers them as a fascinating adjuvant alternative for enhancing bone regeneration and bone-to-implant junction in the early implantation stages. However, stable loading and delivery efficiency of rhBMPs on the implant surfaces involve major concerns because of the harsh wearing condition under load during implantation. In this study, to achieve successful rhBMP-2 delivery, a nanoporous surface structure is introduced on the sandblasting with large grit and acid-etching (SLA)-treated titanium (Ti) surface via the tantalum (Ta) target-ion induced plasma sputtering (TIPS) technique. Unlike oxidation-induced surface nanoporous fabrications on a Ti surface, TIPS-treated surfaces provide excellent structural unity of the nanoporous structure with the substrate due to their etching-based fabrication mechanism. SLA/TIPS-treated Ti exhibits distinct nanoporous structures on the microscale surface geometry and better hydrophilicity compared with SLA-treated Ti. A sufficiently empty nanoporous surface structure combined with the hydrophilic property of SLA/TIPS-treated Ti facilitates the formation of a thick and uniform coating layer of rhBMP-2 on the surface without any macro- and microcoagulation. Compared with the SLA-treated Ti surface, the amount of coated rhBMP-2 increases up to 63% on the SLA/TIPS-treated Ti surface. As a result, the in vitro pre-osteoblast cell response of the SLA/TIPS-treated Ti surface, especially cell adhesion and differentiation behaviors, improves remarkably. A bone-regenerating direct comparison between the rhBMP-2-coated SLA-treated and SLA/TIPS-treated Ti is conducted on a defective dog mandible model. After 8 weeks of implantation surgery, SLA/TIPS-treated Ti with rhBMP-2 exhibits a better degree of contact area for the implanted bone, which mineralizes new bones around the implant. Quantitative results of bone-in-contact ratio and new bone volume also show significantly higher values for the SLA/TIPS-treated Ti with the rhBMP-2 specimen. These results confirm that an SLA/TIPS-treated surface is a suitable rhBMP-2 carrier for a dental implant to achieve early and strong osseointegration of Ti dental implants.

Abstract:
Porcine reproductive and respiratory syndrome virus (PRRSV) causes an economically important global swine disease. Here we report the development of subunit PRRSV-2 vaccines by expressing swine leucocyte antigen (SLA) class I and class II allele-specific epitope antigens in a robust adenovirus vector. SLA I-specific CD8 and SLA II-specific CD4 T cell epitopes of PRRSV-2 NADC20 were predicted in silico. Stable murine leukaemia cell lines (RMA-S), which are TAP-deficient and lacking endogenous class I epitope loading, were established to express different SLA I alleles. The binding stability of PRRSV T cell epitope peptides with SLA I alleles expressed on RMA-S cells was characterized. Two PRRSV poly-T cell epitope peptides were designed. NADC20-PP1 included 39 class I epitopes, consisting of 8 top-ranked epitopes specific to each of 5 SLA I alleles, and fused to 5 class II epitopes specific to SLA II alleles. NADC20-PP2, a subset of PP1, included two top-ranked class I epitopes specific to each of the five SLA I alleles. Two vaccine candidates, Ad-NADC20-PP1 and Ad-NADC20-PP2, were constructed by expressing the polytope peptides in a replication-incompetent human adenovirus 5 vector. A vaccination and challenge study in 30 piglets showed that animals vaccinated with the vaccines had numerically lower gross and histopathology lung lesions, and numerically lower PRRSV RNA loads in lung and serum after challenge compared to the controls, although there was no statistical significance. The results suggested that the Ad-NADC20-PP1 and Ad-NADC20-PP2 vaccines provided little or no protection, further highlighting the tremendous challenges faced in developing an effective subunit PRRSV-2 vaccine.

Abstract:
Purpose: The objective of this study was to assess the influence of a novel surface of dental implants (ContacTi®) on the osseointegration process in a minipig model. The surface was compared with other existing surfaces on the market (SLA® and SLActive®) by employing bone implant contact analysis (BIC) and implant stability. Method: Twelve minipigs were used with prior authorisation from an ethics committee. Three types of surfaces were tested: SLA® (sand-blasted acid-etched titanium), SLActive® (same but hydrophilic, performed under a nitrogen atmosphere), and ContacTi® (alumina particle bombardment of titanium, bioactivated when treated thermochemically) in 4.1 mm × 8 mm implants with internal connection and a polished neck. Twelve implants of each surface type (N = 36) were placed, sacrificing 1/3 of the animals at 2 weeks of placement, 1/3 at 4 weeks and the remaining 1/3 at 8 weeks. Numerical variables were compared with Analysis of Variance, and the correlation between ISQ and BIC was established with the Spearman’s rank correlation coefficient. Results: SLActive® and ContacTi® surfaces showed elevated osteoconductivity at 4 weeks, maintaining a similar evolution at 8 weeks (large amount of mature lamellar tissue with high maturity and bone quality). The SLA® surface showed slower maturation. The ISQ values in surgery were elevated (above 65), higher at necropsy and higher at 4 and 8 weeks in the SLA® group than in the other two (SLActive® and ContacTi®). No significant correlation was found between ISQ and BIC for each implant surface and necropsy time. Conclusion: The three surfaces analysed showed high RFA and BIC values, which were more favourable for the SLActive® and ContacTi® surfaces. No statistical correlation was found between the RFA and BIC values in any of the three surfaces analysed.

Abstract:
The decreased bone density and increased marrow adiposity that occur with aging may influence the outcome of dental implants. Strontium (Sr), an anabolic agent for the treatment of osteoporosis, has an inhibitory effect on adipogenesis but favors osteogenesis of bone marrow–derived mesenchymal stem cells (BMSCs). However, little is known about the effects and mechanisms of local Sr release on adipogenesis during bone formation in aged bone. In this study, a potential dental implant material, Sr-doped titanium, was developed via a sandblasted, large-grit, and acid-etched (SLA) method combined with a hydrothermal process. The effects of Sr-SLA on initial adhesion, proliferation, intracellular redox state, and adipogenic differentiation of senescent BMSCs were investigated. The in vitro results showed that Sr-SLA promoted spreading of senescent BMSCs via upregulation of the gene and protein expression of integrin β1. In addition, it was revealed that Sr-SLA could reduce intracellular oxidative stress by decreasing the levels of reactive oxygen species and oxygen radicals and increasing the content of glutathione peroxidase. More important, Sr-SLA suppressed lipid droplet production and adipokines expression via downregulation of transcription peroxisome proliferator-activated receptor γ (PPARγ) and signal transducer and activator of transcription 1, thus inhibiting adipogenesis. Finally, the Sr-SLA implants were implanted in tibiae of aged (18-mo-old) Sprague-Dawley rats for 2 and 8 wk. Histomorphometric analysis demonstrated that Sr-SLA implants significantly enhanced osseointegration, and the inhibition effect on marrow adipose tissue formation was moderate. All these results suggest that due to the multiple functions produced by Sr, antiadipogenesis capability and rapid osseointegration were enhanced by the Sr-SLA coatings, which have potential application in dental implantation in the aged population.

Abstract:
Specific leaf area (SLA), the ratio of leaf area to leaf weight, is an important plant characteristic that affects the rate of dry matter production of crop canopies. It is affected by the conditions of growth of both isolated plants and crop communities, but the extent to which various environmental factors impact on SLA under field conditions is not clearly understood. This study was conducted to study the variability in SLA of leaves on the main culm, and in the leaf canopy as an entity, under different conditions of photoperiod, nitrogen and temperature for a number of wheat genotypes grown under field conditions. Five plantings at approximately bimonthly intervals on 12 May, 5 July and 22 September 1993; and on 9 June and 10 August 1994 were made under both natural photoperiod and an extended photoperiod of 20 h. A split plot design with two levels of nitrogen (0 kg N ha−1 and 150 kg N ha−1) as main plots and four genotypes of wheat comprising two spring types (Norseman and Roblin) and two winter types (Ruby and Harus) as subplots was used.SLA of individual leaves varied among leaf positions, but the pattern of variation was dependent on sowing date and genotype. For May and June sowing dates, SLA increased with leaf number up to leaf 5 and then declined with subsequent leaf numbers for the spring genotypes, but increased to leaf 5 and changed little thereafter for the winter types. For July or August sowing and for both spring and winter genotypes, the change in SLA with leaf position was less clear. The results further showed that some of this variability in SLA with leaf position could be accounted for by the mean air temperatures over which the leaves developed. As temperatures increased from 8 °C to 26 °C, SLA increased to a maximum value achieved at 18–20 °C and then declined. However, there was a large scatter of SLA values around 18–20 °C, due partly to some lower SLA values for the July and August sowing dates. This suggests the impact of other factors such as radiation and the degree of mutual shading within the canopy on SLA. Mean canopy SLA reflected the individual leaf values during the period of leaf production, and varied with sowing date and genotype, although the pattern of genotypic variability was inconsistent over sowing dates; it decreased rapidly after spike emergence presumably reflecting leaf aging. Neither nitrogen nor photoperiod had significant effects on SLA on both individual leaf and canopy bases.The results suggest that temperature is one factor affecting SLA under field conditions, but that further work to identify other factors impacting on SLA in the field will be necessary. For application of simulation models to situations in which temperatures are likely to vary, an accounting for the impact of temperature on the SLA of individual leaves would be desirable.

Abstract:
Abstract INTRODUCTION Stereotactic laser ablation (SLA) is an innovative minimally invasive strategy used to treat intracranial tumors. While it is applied commonly in adults as adjuvant therapy for high grade tumors, its use in children is less well understood. At Texas Children's Hospital (TCH), an interdisciplinary team considers SLA, with or without concomitant biopsy, as a diagnostic and treatment strategy in select cases. This study represents our institutional experience over 5 years using SLA for children with brain tumors. METHODS A retrospective chart review was performed for patients less than 18 years old undergoing SLA at TCH from 2012–2016. Demographics, medical history, and surgical outcomes were recorded. Biopsy diagnosis rate, adjuvant treatments, and tumor outcomes are noted. RESULTS >Fourteen children (7 males), with an average age at first surgery of 11.6 years, underwent SLA for WHO I (8), WHO II (1), WHO III (1), WHO IV (2) and unknown (2) tumors. Tumor locations were deep (periventricular, midbrain) in nine cases. Antecedent biopsy was diagnostic in 5 of the 7 patients (71%). SLA without concurrent biopsy was the solo treatment in the other 7 patients (50%). Complete ablation of tumors was confirmed radiographically in 11/14 children. Follow-up time was an average of 2 years. At follow up, 11 children had stable disease, 2 had recurrences, and there was 1 death. One patient developed acute postoperative hydrocephalus requiring temporary ventricular drain placement for cerebrospinal fluid diversion. CONCLUSION SLA is an effective novel adjunctive or primary treatment modality for primary brain tumors in children, with a low complication profile, even in deep locations, and may be easily paired with diagnostic biopsy.

Abstract:
Chez le porc, les trois gènes du CMH de classe I non classiques (gènes SLA-Ib) SLA-6, -7 et -8 sont peu étudiés alors que ce sont des candidats majeurs comme homologues fonctionnels des gènes humains HLA-E, -F et -G qui font l’objet de travaux soutenus de par leur rôle dans la tolérance fœto-maternelle lors de la grossesse chez la femme notamment. Notre objectif a consisté à analyser le polymorphisme, la transcription et l’expression des protéines de ces trois gènes d’intérêt. Nous avons montré que les trois gènes sont transcrits dans une large gamme de tissus, avec une expression prépondérante dans les tissus lymphoïdes, le système digestif et les poumons. Les trois gènes expriment des transcrits qui codent pour des protéines de pleine longueur dont la traduction et la prédiction de conformation sont compatibles avec la présentation de peptides à la surface cellulaire. Les gènes SLA-6 et -7 expriment des transcrits alternatifs qui pourraient coder pour des isoformes solubles, alors qu’un unique transcrit a été trouvé pour le gène SLA-8. Un épissage alternatif dans la région 3’ non codante en aval du codon de terminaison a également été identifié pour SLA-7, suggérant l’existence de mécanismes de régulation post-transcriptionnelle pour ce gène. Les analyses de polymorphisme ont confirmé des variations nucléotidiques limitées mais mis en évidence une variation du nombre de copies du gène SLA-7 selon les animaux. Des analyses sont encore en cours pour caractériser la spécificité d’anticorps monoclonaux dirigés contre les molécules SLA-Ib dans des expériences de transfections transitoires en cultures de cellules. Nos résultats sont une contribution importante à la caractérisation des gènes SLA-Ib chez le porc et permettront de poursuivre avec des approches plus fonctionnelles visant l’analyse de leurs possibles fonctions dans des mécanismes liés à l’immuno-tolérance
In pig, very little information is available on the three non classical MHC class I genes SLA-6, -7 and -8 (SLA-Ib genes). Our aim was to increase knowledge on SLA-Ib genes by studying their polymorphism, transcription and protein expression. Full length transcripts were characterized from thymus and brain of MeLiM pigs resulting in the annotation of 8 exons for SLA-7 and -8 and 7 exons for SLA-6. The three full length cDNAs encode molecules with a predicted folding consistent with peptide presentation. No additional transcript was found for SLA-8 while four and five were detected for SLA-6 and SLA-7, respectively, suggesting that some soluble forms of these molecules may exist. For SLA-7, an alternative spliced variant was found in the 3’UTR of the gene after the termination codon suggesting possible post-transcriptional regulation of the gene. Polymorphism studies confirmed a limited nucleotide polymorphism but revealed an unexpected copy number variation for SLA-7. Ongoing experiments are still in progress to characterize monoclonal antibodies specific of each SLA-Ib molecule in transient transfection systems. Our overall results provided significant new data on SLA-Ib genes and will pave a way toward more functional analyses related to their putative function in immuno-tolerance

Abstract:
A year long learning strategy course was designed and embedded in a Year 8 science curriculum. The Science Learning Strategy (SLS) program aimed to improve student ability to apply learning strategies to science, increase student achievement in science and to augment students' feelings of control over their science learning, so that their perceived competence was maximised. Achievement of these aims was monitored by collecting perceptions from students, parents and the teacher/researcher via a range of devices including questionnaires, work samples and interviews. The program overall was regarded as successfully achieving all three aims by 22 of the 24 students. The other two students found that only some aspects of the course were helpful, and felt they had learned little from the program. Thirty three percent of parents attributed positive changes in their daughter's study and learning strategies to participation in the SLS program (the remainder were unsure, or did not know of any changes). In relation to perception of academic performance, 38% of the parents interviewed believed that the SLS had a positive effect on their daughter's achievement in science. Several of these parents reported very positive effects on performance. The remainder were not sure or did not know if there had been any positive effects. No parents mentioned that the SLS program had caused a drop in science performance. The proportion of parents believing their daughters blamed disappointing results on factors they couldn't control dropped from 45% at the start of the year, to 22% by the end of the SLS program. After the intervention, 33% of parents reported that their daughters had come to believe that their science performance was affected by many factors, most of which they could control.
The teacher/researcher observed strong improvement in student ability to apply learning strategies to science as a result of participation in the program. Students were also observed by the teacher/researcher, to have been assisted by the intervention to realise that their science performance was governed not only by their natural ability, but also by factors such as studying behaviour and affective influences. In particular, the program appeared to the teacher/researcher to have helped students realise that they had control over their use of learning strategies, and that this control could influence their science performance. However, the teacher/researcher found that no statistically significant changes in science achievement resulted from student participation in the SLS course. The other objective of the research was to investigate the extent to which learning strategy education was valued and implemented by Western Australian science teachers. The 218 returned surveys revealed that most respondents recognised the need to teach these skills during science lessons. Seventy six percent of respondents considered the delivery of learning strategy instruction in the lower school science classroom to be as important, or more important, than teaching subject processes and content. Sixty seven percent recognised that improving study strategies can improve confidence and/or motivation.
Many teachers, however, had not been able to convert these views into consistent classroom practice. A moderate proportion of teachers reported teaching a variety of learning strategies; 74% of the respondents agreed that learning strategy instruction could improve performance in science. Only one teacher specifically mentioned incorporating the teaching of learning strategies with instruction in science process and content. As a future outcome of this project, the teacher/researcher will encourage other teachers to embed learning strategy instruction within the science curriculum, so that their students come to feel more in control of their learning and can learn more effectively.

Abstract:
Apesar de o Brasil ser o país com a maior comunidade japonesa fora do Japão, ainda há poucos estudos sobre a aquisição e aprendizagem do português por falantes japoneses. Partindo da descrição do sistema silábico da língua portuguesa (CÂMARA JR., 1970; FERREIRA NETTO, 2001; CRISTÓFARO SILVA, 2009; CAGLIARI, 2007; CAVALIERE, 2005) e da língua japonesa (SHIBATANI, 1987; ITÔ, 1986; McCAWLEY, 1968; HINDS, 1986), pretende-se observar por meio da Análise de Erros (CORDER, 1967) quais as estratégias utilizadas por falantes japoneses em processo de aprendizagem da língua portuguesa para pronunciar duas estruturas silábicas que não existem em sua língua materna: sílabas CVC terminadas em /r/ ou /s/, e sílabas com mais de uma consoante pré-vocálica do tipo CCV, com /r/ ou /l/ ocupando a segunda posição de ataque. A partir dessa observação, busca-se determinar quais dessas estruturas representam maior dificuldade para o aprendiz japonês. Para a composição do corpus, foram criados dezenove nomes fictícios com as estruturas silábicas em questão e sete informantes foram gravados. Ainda que não tenha sido uma pesquisa quantitativa, por meio da comparação dos resultados foi possível verificar a maior facilidade de produzir sílabas CVC em relação às CCV e, para a maioria, o número de acertos foi maior com a consoante /s/ em posição de coda e /r/ na segunda posição de ataque complexo. Quanto à estratégia utilizada, o uso de inserção vocálica foi maior que o de apagamento, exceto quando /r/ ocupa a posição de coda. A pesquisa mostrou que a dificuldade maior ou menor do aprendiz pode ser entendida a partir de processos fonológicos que acontecem na L1, no caso a língua japonesa.
Although Brazil is the country with the largest Japanese community outside Japan, there are few studies about Portuguese acquisition and learning by Japanese speakers. Based on the description of the syllabic system of the Portuguese language (CÂMARA JR., 1970; FERREIRA NETTO, 2001; CRISTÓFARO SILVA, 2009; CAGLIARI, 2007; CAVALIERE, 2005) and of the Japanese language (SHIBATANI, 1987; ITÔ, 1986; McCAWLEY, 1968; HINDS, 1986), we intend to observe through Error Analysis (CORDER, 1967) the strategies used by Japanese learners of Portuguese to pronounce two syllable structures that do not exist in their native language: CVC syllables closed by /r/ or /s/ and CCV syllables with /r/ or /l/ in the second onset position. From this observation, we seek to determine which of these structures represents more difficulty for Japanese learners. To compose the corpus, nineteen fictitious names with the syllabic structure in question were created and seven informants were recorded. Although it has not been a quantitative research, by comparing the results we could verify that it was easier to produce CVC syllables than CCV ones. In addition, for most of the informants, the number of correct production was higher with the consonant /s/ in coda position and /r/ in the second onset position. For the strategy used, the use of vowel insertion was higher than deletion, except when /r/ occupies the coda position. Research has shown that the greater or lesser difficulty of the learner can be understood from phonological processes that occur in L1, in this case the Japanese language.

Abstract:
This report presents a complete package for bistable electromagnetic actuated microvalve. The function of the valve is to control the fuel delivery system in a fuel cell unit for power generation [1,2]. The microvalves were fabricated on top of a single wafer using 8 masking steps. The fabrication processes have a maximum processing temperature of 300 °C, providing potentially a CMOS compatible process. The valve arrays that compromise of 12 valves per 12 MM × 12 MM chip are built completely by surface micromachining. The chip is assembled into a package with fluidic connection parts. The parts were made from the stereo lithography (SLA) frame that was filled with PDMS. The PDMS also acts as a gasket to seal the microvalve from leaking. The fluidic tests show that the whole valve assembly can stand from leaks up to the pressure of 57.4 kPa.

Abstract:
The objective of our studies was to evaluate the assimilative indices of cucumber (‘Pasalimo F1’) and tomato (‘Marissa F1’) transplants, cultivated under various photosynthetic photon flux densities (PPFD) were provided by light-emitting diodes (LEDs). Experiment was performed in phytotron complex of Institute of Horticulture, LRCAF. A system of high-power, solid-state lighting modules with 92 % 638 nm (red) + 665 nm (red) + 731 nm (far red) and 8 % 447 nm (blue) was used in the experiments. The generated PPFD of each type of five solid-state modules was ~200 and ~400 μmol m-2 s-1. Our experiment revealed that increased net assimilation rate (NAR) depended on increased PPFD of cucumber and tomato hybrid. 400 μmol m-2 s-1 LED illumination had positive effect on relative growth rate (RGR). Cucumbers which were grown under 200 μmol m-2 s-1 had bigger leaf area ratio (LAR) and specific leaf area (SLA), their development has been bigger as compared to higher 400 μmol m-2 s-1 PPFD. High PPFD LED illumination had positive effect on leaf weight ratio (LWR), shoot root ratio (SRR) and tomato transplants development. These studies with various photosynthetic photon flux densities (PPFD) and LEDs light should be continued throughout plant vegetation.

Abstract:
Three different ways are employed in the present paper to reduce the secondary flow related total pressure loss. These are nonaxisymmetric endwall contouring, leading edge (LE) fillet, and the combination of these two approaches. Experimental investigation and computational simulations are applied for the performance assessments. The experiments are carried out in the Axial Flow Turbine Research Facility (AFTRF) having a diameter of 91.66cm. The NGV exit flow structure was examined under the influence of a 29 bladed high pressure turbine rotor assembly operating at 1300 rpm. For the experimental measurement comparison, a reference Flat Insert endwall is installed in the nozzle guide vane (NGV) passage. It has a constant thickness with a cylindrical surface and is manufactured by a stereolithography (SLA) method. Four different LE fillets are designed, and they are attached to both cylindrical Flat Insert and the contoured endwall. Total pressure measurements are taken at rotor inlet plane with Kiel probe. The probe traversing is completed with one vane pitch and from 8% to 38% span. For one of the designs, area averaged loss is reduced by 15.06%. The simulation estimated this reduction as 7.11%. Computational evaluation is performed with the rotating domain and the rim seal flow between the NGV and the rotor blades. The most effective design reduced the mass averaged loss by 1.28% over the whole passage at the NGV exit.

Abstract:
Secondary flow minimization is a crucial problem in a turbine passage. In the present paper, three different ways are employed to reduce the secondary flow related total pressure loss. These are nonaxisymmetric endwall contouring, leading edge (LE) fillet, and the combination of these two approaches. Experimental investigation and computational assessment are applied for the performance calculations. The experiments are carried out in an annular Axial Flow Turbine Research Facility (AFTRF) having a diameter of 91.66cm. For the experimental measurement comparison, a reference Flat Insert is installed in the nozzle guide vane (NGV) passage. It has a constant thickness with cylindrical surface and is manufactured by stereolithography (SLA) method. Also, Flat Insert has a backward facing step at the NGV exit, and the effect of this step is analyzed computationally. Four different LE fillets are designed, and they are attached to both cylindrical Flat Insert and the contoured endwall. Total pressure measurements are taken at rotor inlet plane with Kiel probe. The probe traversing is completed with one vane pitch and from 8% to 38% span. For one of the designs, area-averaged loss is reduced by 15.06%. The simulation estimated this reduction as 6.95%. Computational evaluation is also performed at the NGV exit plane. The most effective design reduced the mass-averaged loss by 1.84% on the whole passage. The computational study did not include the rim seal flow between the vane and rotor domain and also rotor simulation was absent. The difference between the measurements and the simulation comes from these two important effects.

Full text
Abstract:
Single crystal (SX) superalloys have wide application in the high pressure turbine section of aero and industrial gas turbine engines due to the unique combination of properties and performance. Since introduction of single crystal casting technology, SX alloy development has focused on increased temperature capability, and major improvements in alloy performance have been associated with the introduction of new alloying elements, including rhenium (Re) and ruthenium (Ru). 3% Re-containing second generation alloys, such as CMSX-4®, PWA 1484 and Rene’ N5 have seen the greatest market utilization and have become the benchmark alloys for comparing new alloy developments. However, Re and Ru are rare elements with limited production/availability and corresponding high costs. This has resulted in significant escalation of SX alloy costs, and consequently, there has been much interest in the development of improved SX superalloys with lower Re or no Re content compared to second generation alloys. Cannon-Muskegon® has developed two new SX superalloys: 1.5% Re CMSX®−8 alloy and CMSX®−7 alloy, which contains no Re, as alternatives to first and second generation alloys for applications which require slightly less ultra high temperature capability compared to CMSX-4 alloy or the improved CMSX-4(SLS) alloy. This paper provides an overview of development and characterization of these SX alloys and alloy modifications, CMSX-8 (SLS) and CMSX-8[B/C](SLS).

Full text
Abstract:
Sulfuric acid corrosion can cause severe damage to concrete and cement composites. There are a variety of approaches to enhancing the sustainability of concrete and mortar one of which is to enhance the durability of concrete using different cement replacement. Granulated blast furnace slag is used in mortar and concrete, as a partial replacement of Portland cement, and this use has resulted in significant savings in the cost of production of concrete. Moreover the use of conventional concrete is notoriously subject to durability and corrosion issues. Laboratory experiments were conducted to investigate the compressive strength of cement mortars samples with cement partially replaced by blast furnace slag. The samples with different share of slag (65, 75, 85 and 95 wt.%) were exposed to a bacterial sulphate environment for 90 days. A decrease in compressive strengths of reference samples by 8% as well as an increase in compressive strengths of all slag-based sampless up to 95 % have been observed. Surface structure and chemical com-positions of cement mortars´ leachates confirmed a deterioration process under the microbial exposure of Acidithioba-cillus thiooxidans.

Full text
Abstract:
The article presents the results of testing the effect of partial replacement of sand with fine copper slag waste on the thermal properties of hardened concrete. The impact of the replacement on mechanical properties (ie. compressive and tensile strength of concrete) was also investigated. The thermal properties of the concrete were determined using the non-stationary method with the ISOMET 2114 device. Tests were performed on concrete containing three different types of cement (CEM I, CEM II and CEM III). A total cement content of 360 kg/m3 was assumed in the compositions of all concrete mixes with a water-cement ratio of 0.45. Replacing 66% of the sand volume with copper slag waste caused a decrease in thermal conductivity by about 4–8% in relation to the reference concrete. In addition, the compressive strength of concrete containing copper slag increased by about from 4–21% in relation to the reference concrete.

Abstract:
This report describes the situation of rural Youths Neither in Employment, nor in Education or Training (NEET) aged between 15-34 years old, over the last decade (2009-2019) in Slo-vakia. To achieve this goal, the report utilised indicators of youth population, youth employ-ment and unemployment, education and NEETs distribution and amount of ESLET in Slovakia according to different level of urbanisation (cities, towns and suburbs and towns). There are more male than females living in Slovakia. However, there are more females living in rural areas. Youth unemployment has been rising every year since 2009, peaking in 2012/2013, and after this peak it has decreased gradually leading to the lowest unemployment rate in a decade for the age category 15-39 in 2018-2019. Since the year 2010 the employment rate has been gradually increasing in all degrees of urbanisation. In last decade (2009-2019), the population aged 15-24 years old in Slovakia has become more educated. The highest increa-se was in last decade at level ISCED 5-8 in rural areas. ESLET has gradually increased in Slo-vakia nationwide. Between the years 2009-2019, there were an increased number of ESLET females in rural areas. The share of NEETs has slightly decreased in last decade in Slovakia.
