Bubble dissolution in molten polymers and its role in rotational molding (1999)

Abstract The presence of bubbles is inherent in the rotational molding process and can often cause poor quality in rotomolded parts. In an effort to gain a fundamental understanding of bubble removal in polymer melts, a model that includes diffusion, surface tension, and viscosity effects has been implemented. This work has been complemented with experiments performed in a heated chamber, which enabled the visualization of the bubble formation and removal process. It was concluded that bubble removal is mainly diffusion controlled and is not influenced significantly by melt viscosity when the latter lies within ranges typical for rotational molding resins. Air concentration in the bulk of the polymer melt and initial bubble size were found to be of great importance. The application of pressure after the polymer has melted accelerates the dissolution rate, owing to an increased driving force for diffusion.

In Situ Fabrication of AlN Coating by Reactive Plasma Spraying of Al/AlN Powder (2011)

Reactive plasma spraying is a promising technology for the in situ formation of aluminum nitride (AlN) coatings. Recently, it became possible to fabricate cubic-AlN-(c-AlN) based coatings through reactive plasma spraying of Al powder in an ambient atmosphere. However, it was difficult to fabricate a coating with high AlN content and suitable thickness due to the coalescence of the Al particles. In this study, the influence of using AlN additive (h-AlN) to increase the AlN content of the coating and improve the reaction process was investigated. The simple mixing of Al and AlN powders was not suitable for fabricating AlN coatings through reactive plasma spraying. However, it was possible to prepare a homogenously mixed, agglomerated and dispersed Al/AlN mixture (which enabled in-flight interaction between the powder and the surrounding plasma) by wet-mixing in a planetary mill. Increasing the AlN content in the mixture prevented coalescence and increased the nitride content gradually. Using 30 to 40 wt% AlN was sufficient to fabricate a thick (more than 200 µm) AlN coating with high hardness (approximately 1000 Hv). The AlN additive prevented the coalescence of Al metal and enhanced post-deposition nitriding through N2 plasma irradiation by allowing the nitriding species in the plasma to impinge on a larger Al surface area. Using AlN as a feedstock additive was found to be a suitable method for fabricating AlN coatings by reactive plasma spraying. Moreover, the fabricated coatings consist of hexagonal (h-AlN), c-AlN (rock-salt and zinc-blend phases) and certain oxides: aluminum oxynitride (Al5O6N), cubic sphalerite Al23O27N5 (ALON) and Al2O3. The zinc-blend c-AlN and ALON phases were attributed to the transformation of the h-AlN feedstock during the reactive plasma spraying. Thus, the zinc-blend c-AlN and ALON phases were not included in the feedstock and were not formed through nitriding of the Al.
Intraarticular injection of sodium hyaluronate plus steroid versus steroid in adhesive capsulitis of the shoulder. (1998)

To determine the efficacy of a combined treatment--namely hyaluronan and corticosteroid injection plus physical exercises in the management of established idiopathic capsulitis of the shoulder--30 consecutive subjects with adhesive capsulitis were selected for the study. The diagnosis of adhesive capsulitis was established on the basis of a clinical history of spontaneous shoulder pain, shoulder examination showing passive limitation in conformity with capsular pattern, cervical examination excluding significant dysfunction of this area, plain radiographs excluding other significant shoulder diseases, or sonographic examination showing capsule shrinkage in affected joint. The patients were randomly allocated to receive intraarticular injections of sodium hyaluronate (20 mg) plus steroid (20 mg triamcinolone acetonide) and physiotherapy or intraarticular injections of steroid (20 mg triamcinolone acetonide) alone and physiotherapy. The intraarticular injections were performed at 15-day intervals in the first month and then monthly for 6 months. Physiotherapy was performed for 4-12 weeks. The results indicate an improvement of pain and joint motion after 6 months in all patients, especially in the patients treated with sodium hyaluronate. Intraarticular hyaluronan combined with triamcinolone acetonide and shoulder exercises may improve adhesive capsulitis. This drug possibly acts on shoulder tissue retraction by means of its influence on osmotic pressure and synovial fluid volume control.
Mechanical, thermal, and viscoelastic investigations on expanded perlite–filled high-density polyethylene composite (2018)

Perlite is a glassy amorphous volcanic rock and generally used in construction industries. Possible uses of perlite powder in polymeric composites allow producing value-added products. In this study, expanded Turkish perlite (TP) powder was characterized by particle size distribution and Brunauer–Emmett–Teller analysis. TP-filled high-density polyethylene (HDPE) composites were manufactured via thermokinetic mixer by adding various weight fractions of TP powder (5, 10, 20, and 30 wt%) into HDPE matrix. Produced composites were characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis, dynamic mechanic analysis, X-ray diffraction, and mechanical and thermal conductivity tests. From mechanical tests, it was observed that HDPE + 5% TP exhibited the greatest tensile strength. Flexural strength of the TP-filled HDPE composite was increased with the increasing TP content. Morphological properties of TP-filled HFPE composites were examined by scanning electron microscopy. As the weight fraction of TP was increased, storage modulus and loss modulus of the composites were increased. Moreover, the relaxation peak of HDPE was increased by the incorporation of TP into HDPE.

Virulence Potential and Genome-Wide Characterization of Drug Resistant Streptococcus pneumoniae Clones Selected In Vivo by the 7-Valent Pneumococcal Conjugate Vaccine (2013)

We used mouse models of pneumococcal colonization and disease combined with full genome sequencing to characterize three major drug resistant clones of S. pneumoniae that were recovered from the nasopharynx of PCV7-immunized children in Portugal. The three clones--serotype 6A (ST2191), serotype 15A (ST63) and serotype 19A (ST276) carried some of the same drug resistance determinants already identified in nasopharyngeal isolates from the pre-PCV7 era. The three clones were able to colonize efficiently the mouse nasopharyngeal mucosa where populations of these pneumococci were retained for as long as 21 days. During this period, the three clones were able to asymptomatically invade the olfactory bulbs, brain, lungs and the middle ear mucosa and established populations in these tissues. The virulence potential of the three clones was poor even at high inoculum (10(5) CFU per mouse) concentrations in the mouse septicemia model and was undetectable in the pneumonia model. Capsular type 3 transformants of clones 6A and 19A prepared in the laboratory produced lethal infection at low cell concentration (10(3) CFU per mouse) but the same transformants became impaired in their potential to colonize, indicating the importance of the capsular polysaccharide in both disease and colonization. The three clones were compared to the genomes of 56 S. pneumoniae strains for which sequence information was available in the public databank. Clone 15A (ST63) only differed from the serotype 19F clone G54 in a very few genes including serotype so that this clone may be considered the product of a capsular switch. While no strain with comparable degree of similarity to clone 19A (ST276) was found among the sequenced isolates, by MLST this clone is a single locust variant (SLV) of Denmark14-ST230 international clone. Clone 6A (ST2191) was most similar to the penicillin resistant Hungarian serotype 19A clone.
Integrability and structural stability of solutions to the Ginzburg–Landau equation (1986)

The integrability of the Ginzburg–Landau equation is studied to investigate if the existence of chaotic solutions found numerically could have been predicted a priori. The equation is shown not to possess the Painlevé property, except for a special case of the coefficients that corresponds to the integrable, nonlinear Schrödinger (NLS) equation. Regarding the Ginzburg–Landau equation as a dissipative perturbation of the NLS, numerical experiments show all but one of a family of two-tori solutions, possessed by the NLS under particular conditions, to disappear under real perturbations to the NLS coefficients of O(10−6).
A multichannel photometer for chemical analysis (1974)

A novel type of photometer has been constructed which can measure 3000 samples in an hour. This capacity is achieved by having 24 separate light paths for the samples which are held in a cuvette rack. Monochromatic light is divided into individual channels with fibre optics and 24 silicon photodiodes are multiplexed into a common amplifier. The instrument contains a minicomputer that performs several photometric functions, thus eliminating a number of the controls. These special problems encountered in the construction of this type of photometer are described. This type of instrument gives a high measurement capacity and simultaneously retains the flexibility of simpler manual instruments.
N-Arylcyano-β-diketiminate Methallyl Nickel Complexes: Synthesis, Adduct Formation, and Reactivity toward Ethylene (2013)

The syntheses and structures of new bis-N-phenyl-4-cyano-β-diketiminate (1), bis-N-phenyl-2-cyano-β-diketiminate (2), N-phenyl-4-cyano-N-phenyl-2-cyano-β-diketiminate (3), N-phenyl-4-cyano-N-2,6-diisopropylphenyl-β-diketiminate (4), N-phenyl-2-cyano-N-2,6-diisopropylphenyl-β-diketiminate (5), and methallyl nickel complexes [L1Ni(η3-methallyl)] (6), [L2Ni(η3-methallyl)] (7), [L4Ni(η3-methallyl)] (8), and [L5Ni(η3-methallyl)] (9) from the reaction of deprotonated ligands 1/2, 4/5, and methallylnickel chloride dimer are reported. Subsequent reactions of complexes 6–9 with tris(pentafluorophenyl)boron give rise to new adducts [L1Ni(η3-methallyl)]·2B(C6F5)3 (10), [L2Ni(η3-methallyl)]·2B(C6F5)3 (11), [L4Ni(η3-methallyl)]·B(C6F5)3 (12), and [L5Ni(η3-methallyl)]·B(C6F5)3 (13), where B(C6F5)3 is coordinated to the cyano group. New compounds are characterized by NMR, IR, and mass spectrometry techniques, and crystal structures of most compounds are obtained and described. Complexes 6–9, adducts 10–13, and adducts 10–13 with 5 equiv of B(C6F5)3 have been investigated toward ethylene activation. Complexes 6–9 were inactive toward ethylene even at 60 °C, while adducts 10–13 showed reactivity toward ethylene; adding 5 equiv of B(C6F5)3 to adducts 10–13 leads to an increase in reactivity toward ethylene. Adducts 10 and 11 alone and with 5 equiv of B(C6F5)3 catalyze the oligomer formation, while adducts 12 and 13 by the same conditions catalyze the polyethylene formation. Adduct 13 activity is five times higher with respect to 12 at 50 °C and two times higher at 70 °C. The formation of branched moderate molecular weight PE by 12/B(C6F5)3 and 13/B(C6F5)3 is observed.

Competitive Complexation/Solvation Theory of Solvent Extraction. III. Influence of Active Solvents on Acid Solvent Extraction by Amine Based Extractants (2003)

Competitive complexation/solvation theory is used to interpret the influence of active solvents on solvent extraction of acids by amine-based extractants. This theory is based on the modified competitive preferential solvation theory, the concept of amphoteric properties of extractants, and the concept of changing aggregation structures when extractant loading increases. Active solvent concentration parameter is introduced to the quantitative consideration of the extraction systems. The paper discusses four possible stages of extraction behavior, interaction mechanisms, and aggregate structures formation, depending on solute–solvent affinity constant and concentration ratios. The influence of different types of active solvents in each stage is analyzed. Mathematical description is introduced for the quantification of results and process simulation. It gives a key for preliminary quantitative prediction of suitable extraction systems.
Association between corticosteroids and intubation or death among patients with COVID-19 pneumonia in non-ICU settings: an observational study using of real-world data from 51 hospitals in France and Luxembourg (2020)

Abstract Objective To assess the effectiveness of corticosteroids on outcomes of patients with mild COVID-19 pneumonia. Methods We used routine care data from 51 hospitals in France and Luxembourg to assess the effectiveness of corticosteroids at 0.8 mg/kg/day eq. prednisone (CTC group) vs standard of care (no-CTC group) among patients ≤ 80 years old with COVID-19 pneumonia requiring oxygen without mechanical ventilation. The primary outcome was intubation or death at Day 28. Baseline characteristics of patients were balanced using propensity score inverse probability of treatment weighting. Results Among the 891 patients included in the analysis, 203 were assigned to the CTC group. At day 28, corticosteroids did not reduce the rate of the primary outcome (wHR 0.92, 95% CI 0.61 to 1.39) nor the cumulative death rate (wHR 1.03, 95% CI 0.54 to 1.98). Corticosteroids significantly reduced the rate of the primary outcome for patients requiring oxygen ≥ at 3L/min (wHR 0.50, 95% CI 0.30 to 0.85) or C-Reactive Protein (CRP) ≥ 100mg/L (wHR 0.44, 95%CI 0.23 to 0.85). We found a higher number of hyperglycaemia events among patients who received corticosteroids, but number of infections were similar across the two groups. Conclusions We found no association between the use of corticosteroids and intubation or death in the broad population of patients ≤80 years old with COVID-19 hospitalized in non-ICU settings. However, the treatment was beneficial for patients with ≥ 3L/min oxygen or CRP ≥ 100mg/L at baseline. These data support the need to confirm the right timing of corticosteroids for patients with mild COVID. Short summary We assessed the effectiveness of corticosteroids among patients ≤ 80 years old with COVID-19, in non-ICU settings. Our results support the use of corticosteroids for patients receiving oxygen at ≥3L/min or with a C-reactive protein ≥ 100mg/L at baseline.
Study of ultrathin Co films grown on Si(111) substrates (2008)

Ultrathin Co films were grown on vicinal Si(111) substrate with Cu buffer layers. Room temperature ferromagnetic behaviour of Co layer thicker than 4 monolayers was confirmed by the magneto-optical Kerr effect. Ferromagnetic resonance measurements have proven the coexistence of the magnetocrystalline anisotropy along with the growth- and vicinal induced uniaxial out-of-plane and in-plane contributions. Multi-jump hysteresis loops were observed for selected in-plane orientations of magnetic field which is explained by the competition of different anisotropy contributions.
Control architecture for predictive and optimal vehicle operations in a single vehicle environment (2023)

There is disclosed a cloud computing control system for vehicle speed control and also for control of a vehicle in a platoon. The cloud computing control system determines a speed trajectory and neutral coasting command for a first vehicle of the platoon and a vehicle controller determines a reference speed for the first vehicle in response to the speed trajectory and the neutral coasting command, and is response to one or more vehicle specific factors associated with the first vehicle.
Content-based search of video using color, texture, and motion (2002)

We present an implementation of a system for content-based search and retrieval of video based on low-level visual features. The system consists of three parts, automatic video partition, feature extraction, video search and retrieval. Three primary features, color texture and motion are used for indexing. They are represented by color histograms, Gabor texture features, and motion histograms. Most of the processing is done directly in the MPEG compressed domain. Testing on sports and movie databases have shown good retrieval performance.
Direct measurement of thermal lensing in Cr/sup 3+/-doped colquiirities (1998)

Summary form only given. We have utilized the results of previous studies in the development of a two dimensional code that takes into account the quantum defect, upconversion, and thermal quenching of fluorescence. This code provides the spatial distribution of temperature, upperstate lifetimes, and heating sources within a laser rod under longitudinal pumping, for all the colquiirite laser materials. The output of this code for a 4-mm-diameter, 1.5% Cr:LiSrGaAlF/sub 6/ rod is shown for 1 W of pump power. Thermal lensing has not yet been considered in end-pumped colquiirite laser systems.
MEK5 and ERK5 are mediators of the pro-myogenic actions of IGF-2 (2009)

During the differentiation of muscle satellite cells, committed myoblasts respond to specific signalling cues by exiting the cell cycle, migrating, aligning, expressing muscle-specific genes and finally fusing to form multinucleated myotubes. The predominant foetal growth factor, IGF-2, initiates important signals in myogenesis. The aim of this study was to investigate whether ERK5 and its upstream MKK activator, MEK5, were important in the pro-myogenic actions of IGF-2. ERK5 protein levels, specific phosphorylation and kinase activity increased in differentiating C2 myoblasts. ERK5-GFP translocated from the cytoplasm to the nucleus after activation by upstream MEK5, whereas phospho-acceptor site mutated (dominant-negative) ERK5AEF-GFP remained cytoplasmic. Exogenous IGF-2 increased MHC levels, myogenic E box promoter-reporter activity, ERK5 phosphorylation and kinase activity, and rapidly induced nuclear localisation of ERK5. Transfection with antisense Igf2 decreased markers of myogenesis, and reduced ERK5 phosphorylation, kinase and transactivation activity. These negative effects of antisense Igf2 were rescued by constitutively active MEK5, whereas transfection of myoblasts with dominant-negative MEK5 blocked the pro-myogenic action of IGF-2. Our findings suggest that the MEK5-ERK5 pathway is a novel key mediator of IGF-2 action in myoblast differentiation.

A case of early gastric cancer successfully diagnosed by magnifying endoscopy with narrow band imaging system (2010)

症例は67歳男性。胃体中部後壁に径20mmの境界不明瞭な褪色調の不整粘膜を指摘された。内視鏡下生検では悪性を疑う所見も認めたが，再生異型との鑑別が困難な病理像であった。確定診断をつけるため行ったNBI併用拡大内視鏡検査では境界を有した範囲に特徴的な異常血管を認め，高分化腺癌と診断でき，内視鏡的粘膜下層剥離術（ESD）で一括切除した。病理診断は内視鏡診断と一致した高分化粘膜内癌であり，内視鏡的に根治切除できた。本症例は通常内視鏡観察，内視鏡下生検で診断困難であった早期胃癌をNBI併用拡大内視鏡で診断し，内視鏡的に切除し得た貴重な症例と考えられたため，報告する。
