Measuring on main kinetic parameters of molecular catalyst for olefin polymerization using high-pressure-type quenched flow reactor

Ziegler-Natta catalysts are generally obtained by the combination of a transition metal complex with an alkylaluminium compound and possibly another co-catalyst. For molecular Ziegler-Natta catalyst, generally, the active species is a cationic compound. However, in regards to the actives species, the olefin may compete in the polymerization medium with other metal alkyl, the solvent or the counteranion. Thus, it is not an easy task to determine the total active metal site fraction which remains an important challenge in the field of polyolefins. Several methods have been developed to perform this measurement. Among these the most reliable one is rely on the determination of number of macromolecules formed initially, and it requires working in initial controlled regime where the chain transfer reactions are very limited. It should be possible to achieve the controlled regime for molecular catalyst for time going from several milliseconds to fraction of second. This means that technically demanding fast kinetic techniques such as quenched flow technique are necessary for the investigation of kinetic parameters of olefin polymerization catalysts. Up to now this technique has been only implemented in very mild conditions. Recently a stopped flow reactor operating at high temperature and high pressure has been developed in Lyon. In the present study, the usefulness of this reactor for measuring the chain propagation rate constant kp and the fraction of metal active site [M*]/[M] is assessed. In the first part of this work we have focused on the investigation of some metallocene-based catalysts. In particular, we have observed how these catalysts behave at initial stage of polymerization, when they are activated with different co-catalyst and in some case a kinetic description was also possible. The last part of this work was dedicated to kinetic study of some post-metallocene catalysts such as amine bisphenolate and (bis phenoxy-imine) -Zr and -Ti based complexes activated with MAO in a large range of polymerization temperatures. A successful kinetic investigation of Bis(cumyl)[ONNO]ZrBz2 complex activated with MAO/tBu2-PhOH has been performed which allowed the determination of [M*]/[M], kp and activation parameters such as H‡ and S‡. In the case of [N-(3-tert-butylsalicylidene)-2,3,4,5,6 pentafluoroanilinato] titanium dichloride activated with MAO an original changing in kinetic regime is reported by increasing the polymerization temperature

Advanced testbed for tiltrotor aeroelastics

The ATTILA project is aimed at the design, manufacture and testing of an advanced testbed for aeroelastic wind tunnel testing of tiltrotor aircraft. The testbed will consist of a suitably instrumented aeroelastically scaled cantilevered half-wing with powered nacelle-proprotor system representative of the full-scale NGCTR-TD design. Advanced fiber optic sensor and contactless rotating power and data transfer techniques will be used. The design process, coupled with test iterations, is supported by detailed structural and aeroelastic simulations using a range of complementary codes. The ATTILA testbed will first be subjected to a wind-on shakedown test in the DNW LLF 6x6m test section in Froude scaled conditions. After the system functionality and structural dynamic characteristics have been verified, a second data gathering test will be performed in the NASA TDT heavy-gas transonic dynamics wind tunnel in simultaneous Froude and Mach scaled conditions, selected as subcontractor to NLR for its unique worldwide capability of meeting the full test requirements in terms of aeroelastic scaling capability, test Mach number, and model size. Testing will be performed in three mass/stiffness configurations covering 3x25 test points with test speeds up to the NGCTR-TD whirl flutter speed (at least M = 0.56). The proposed test campaign provides the highest possible fidelity experimental demonstration of the whirl flutter characteristics of the NGCTR-TD prior to high-speed flight testing in 2024-2025. Its productivity and safety will be ensured through the introduction of real-time modal damping analysis. The post-test data analysis phase includes a test-to-code correlation study in which the analytical models derived by the consortium are validated against the test results. Engaging a significant subcontractor (NASA), this 54-months €6,525,261 valued action is composed of 2 research centres (NLR, DLR), 1 non-profit foundation (DNW), 1 university (POLIMI) and 1 SME (Technobis).
Case—Inkjet Printer Pricing

Inkjet printers are the most commonly owned printers because of their low cost, high printing quality, and ease of use. The four major inkjet printer manufacturers are Canon, Epson, Hewlett-Packard, and Lexmark. The inkjet printer business has adopted the “bait and hook” business strategy, offering the basic printer product at a low (possibly below cost) price while charging a higher price for their proprietary ink cartridges. Table 1 shows the pricing of different ink jet printers and ink cartridges from the four major manufacturers. With technology advancement, inkjet printers have improved in quality and reduced in price. As seen in Table 1, the printer (being more technologically complex to make than the ink cartridge) is relatively inexpensive. This is a business tactic used to attract more people to buy the printer. The manufacturers are trying to improve their overall profit margin by charging higher prices than they would have normally done for their proprietary ink cartridges. The setting of printer and cartridge prices must therefore be closely linked and studied, as they affect the overall profitability and survival of the printer company. According to LYRA research (http://www.lyra. com/), the total revenue from inkjet printers and ink cartridges exceeded $45 billion in 2006. I.T. Strategies (http://www.it-strategies.com/) expects the inkjet printer market to grow to $58 billion by 2009. It expects the largest segment of the revenue to come from ink cartridges, with the revenue rising from $20 billion in 2004 to $33 billion in 2009. The printer business is very lucrative, and it is crucial for the survival of a company that produces printers to use a “good and flexible” business decision tool to price the printer and ink cartridges.

Examining the latent class structure of CO2 hypersensitivity using time course trajectories of panic response systems

Carbon dioxide (CO2) hypersensitivity is hypothesized to be a robust endophenotypic marker of panic spectrum vulnerability. The goal of the current study was to explore the latent class trajectories of three primary response systems theoretically associated with CO2 hypersensitivity: subjective anxiety, panic symptoms, and respiratory rate (fR).Participants (n = 376; 56% female) underwent a maintained 7.5% CO2 breathing task that included three phases: baseline, CO2 air breathing, and recovery. Growth mixture modeling was used to compare response classes (1…n) to identify the best-fit model for each marker. Panic correlates also were examined to determine class differences in panic vulnerability.For subjective anxiety ratings, a three-class model was selected, with individuals in one class reporting an acute increase in anxiety during 7.5% CO2 breathing and a return to pre-CO2 levels during recovery. A second, smaller latent class was distinguished by elevated anxiety across all three phases. The third class reported low anxiety reported during room air, a mild increase in anxiety during 7.5% CO2 breathing, and a return to baseline during recovery. Latent class trajectories for fR yielded one class whereas panic symptom response yielded two classes.This study examined CO2 hypersensitivity in one of the largest samples to date, but did not ascertain a general population sample thereby limiting generalizability. Moreover, a true resting baseline measure of fR was not measured.Two classes potentially representing different risk pathways were observed. Implications of results will be discussed in the context of panic risk research.
PLANT FOR EXPLOITING THE TIDAL ENERGY

Plant for exploiting the tidal energy of the sea, comprised of a vertically arranged pump which is anchored to the sea bottom and is actuated by means of a float connected to the piston, and special antireturn valves intended to impulse the water through pressure pipes to a pressure accumulator from which the water passes with adequate pressure to a turbine which drives an electric generator. The pump is comprised of two coaxial tubes which slide one inside the other, the internal pipe acting as a piston connected to a surface buoy which transmits the motion to the internal tube, while the external tube is anchored at the bottom of the sea and is maintained in vertical position by means of floats fixed at its upper extremity. The movement of the waves, or tide, actuates said pump which, in turn, operates the plant.

Efficacy of Tie2 Receptor Antagonism in Angiosarcoma

Angiosarcomas are malignant endothelial cell tumors with few effective systemic treatments. Despite a unique endothelial origin, molecular candidates for targeted therapeutic intervention have been elusive. In this study, we explored the tunica internal endothelial cell kinase 2 (Tie2) receptor as a potential therapeutic target in angiosarcoma. Human angiosarcomas from diverse sites were shown to be universally immunoreactive for Tie2. Tie2 and vascular endothelial growth factor receptor (VEGFR) antagonists inhibited SVR and MS1-VEGF angiosarcoma cell survival in vitro. In the high-grade SVR cell line, Tie2 and VEGF antagonists inhibited cell survival synergistically, whereas effects were largely additive in the low-grade MS1-VEGF cell line. Xenograft modeling using these cell lines closely recapitulated the human disease. In vivo, Tie2 and VEGFR inhibition resulted in significant angiosarcoma growth delay. The combination proved more effective than either agent alone. Tie2 inhibition seemed to elicit tumor growth delay through increased tumor cell apoptosis, whereas VEGFR inhibition reduced tumor growth by lowering tumor cell proliferation. These data identify Tie2 antagonism as a potential novel, targeted therapy for angiosarcomas and provide a foundation for further investigation of Tie2 inhibition, alone and in combinations, in the management of this disease.
Associations among Gender, Coping Patterns and Functioning for Individuals with Chronic Pain: A Systematic Review

BACKGROUND: Developing strategies for coping with chronic pain is an integral part of successfully living with this often debilitating health condition. While gender differences in pain coping strategies have long been investigated, the relationship between gender-specific engagement in coping and associated functioning in individuals experiencing chronic pain is yet to be clearly understood. OBJECTIVE: The present systematic review focused on studies that address these relationships to critically evaluate the available evidence. METHODS: A systematic search was conducted using MEDLINE via Ovid, EMBASE, PsycINFO and CINAHL, with 7247 titles retrieved. To be included, studies had to be in English, focus on adult participants, consider chronic nonmalignant pain, use measures of coping and functioning (or disability), report on gender-specific outcomes (for coping and functioning [or disability]), and investigate a relationship among gender, coping and functioning. One researcher screened abstracts and full-text articles, and extracted and tabulated data, while two researchers independently assessed potential articles for eligibility and methodological quality. RESULTS: Only seven studies met the inclusion criteria – six of high quality and one of moderate quality. The presented findings suggest that women in pain are more likely to use coping strategies considered to be maladaptive, resulting in poorer functioning, while men tend to engage in coping strategies considered to be adaptive, leading to better functional outcomes. CONCLUSIONS: While there is some evidence supporting gender-specific engagement in coping and associated functioning, future research is necessary to expand understanding of these interrelations.
Psoas Muscle Architectural Design, In Vivo Sarcomere Length Range, and Passive Tensile Properties Support Its Role as a Lumbar Spine Stabilizer

Controlled laboratory and cross-sectional study designs.To determine psoas major (PM) muscle architectural properties, in vivo sarcomere-length operating range, and passive mechanical properties.PM is an important hip flexor but its role in lumbar spine function is not fully understood. Several investigators have detailed the gross anatomy of PM, but comprehensive architectural data and in vivo length-tension and passive mechanical behaviors have not been documented.PM was isolated in 13 cadaver specimens, permitting architectural measurements of physiological cross-sectional area (PCSA), normalized fiber length (Lf), and Lf:muscle length (Lm) ratio. Sarcomere lengths were measured in vivo from intraoperative biopsies taken with the hip joint in flexed and extended positions. Single-fiber and fiber bundle tensile properties and titin molecular weight were then measured from separate biopsies.Architecturally, average PCSA was 18.45 ± 1.32 cm2, average Lf was 12.70 ± 2 cm, and average Lf: Lm was 0.48 ± 0.06. Intraoperative sarcomere length measurements revealed that the muscle operates from 3.18 ± 0.20 μm with hip flexed at 10.7° ± 13.9° to 3.03 ± 0.22 μm with hip flexed at 55.9° ± 21.4°. Passive mechanical data demonstrated that the elastic modulus of the PM muscle fibers was 37.44 ± 9.11 kPa and of fiber bundles was 55.3 ± 11.8 kPa.Analysis of PM architecture demonstrates that its average Lf and passive biomechanical properties resemble those of the lumbar erector spinae muscles. In addition, PM sarcomere lengths were confined to the descending portion of the length-tension curve allowing the muscle to become stronger as the hip is flexed and the spine assumes a forward leaning posture. These findings suggest that the human PM has architectural and physiologic features that support its role as both a flexor of the hip and a dynamic stabilizer of the lumbar spine.
Reach: russian european alliance for research among women, children and adolescents impacted by hiv, tb and hcv

Pregnant women, children and adolescents are priority populations in the global public health response to the epidemics of HIV, TB and HCV.The high burden of intersecting epidemics of these 3 infections pose a major public health challenge to Russia and the broader European region. The global health goals of ending AIDS, reducing
TB deaths and new HCV cases by 90% by 2030 can only be realized if the unique health needs are considered and targeted research to these priority populations is undertaken to optimise the impact of innovations in diagnostics and treatment. REACH builds on long-standing, successful collaboration between European clinical research networks with track records of delivering innovative research across the three infections with leading collaborators from 7 centres of excellence in Siberian, Northwestern and Central districts of the Russian Federation. The goals of REACH are: 1)To conduct joint research to better understand the epidemiology, disease progression, treatment and outcomes of HIV, TB and HCV mono and co-infections among pregnant women, children and adolescents in the RF: 2)To exchange knowledge, build capacity and prepare for future collaborative research on HIV, HCV and TB in children, adolescents and pregnant women in the RF, including women and young people. REACH will fill the knowledge and data gaps on HIV epidemic affecting children, adolescents and pregnant women across Russia and provide new data on long-term ART toxicity, HIV resistance, HCV and TB coinfections and comorbidities in this setting. It will develop future studies of new diagnostics and preventive TB treatment and the use of novel therapies for HCV in children in real-world settings. REACH will promote geographic expansion of the collaborative research in maternal and child health in Europe with a broad and long-lasting impact. It will also build capacity for improved coordination and integration between European and Russian research centres beyond 2020
Microrheology of two-dimensional active colloidal crystals and glasses

Self-propelling colloidal particles, originally designed to mimic living microorganims, offer exciting opportunities to engineer smart materials equipped with activity. To date, the behavior of synthetic microswimmers has been extensively studied in homogeneous environments, close to confinements and in semi-dilute suspensions. However, for materials’ design, the use of solid-like phases, such as crystals and glasses, is highly desirable. While recent numerical simulations have invested a lot of effort in understanding the structural and mechanical properties of dense colloidal materials with activity, experiments significantly lag behind. One difficulty stems, for instance, from the presence of short-range attractive forces that affect the active motion when two of more microswimmers come near contact. 

In this project, we will investigate the mechanical properties of dense monolayers made partly or entirely of self-propelling colloids using microrheology. We will assemble colloidal monolayers at a flat oil/water interface, where long-ranged repulsive forces will lead to the formation of crystals and glasses with loosely-packed configurations, i.e. with particles that are far from contact. We will mix passive Brownian particles with a controlled amount of active platinum coated particles that self-propel due to a catalytic reaction with hydrogen peroxide dispersed in water. We will elucidate the intimate relation between structure, activity and mechanical properties of dense active suspensions using microrheology experiments, in which we will analyse the fluctuations of a probe driven through the active material by means of an optical tweezing. Our results will shed new light on the unexplored physics of active crystals and glasses and provide a protocol to quantify their mechanical properties. While the proposal research is primarily fundamental in nature, our findings will serve as benchmarks for the design of novel active materials and devices.
Modeling Complex System Correlation Using Detrended Cross-Correlation Coefficient

The understanding of complex systems has become an area of active research for physicists because such systems exhibit interesting dynamical properties such as scale invariance, volatility correlation, heavy tails, and fractality. We here focus on traffic dynamic as an example of a complex system. By applying the detrended cross-correlation coefficient method to traffic time series, we find that the traffic fluctuation time series may exhibit cross-correlation characteristic. Further, we show that two traffic speed time series derived from adjacent sections exhibit much stronger cross-correlations than the two speed series derived from adjacent lanes. Similarly, we also demonstrate that the cross-correlation property between the traffic volume variables from two adjacent sections is stronger than the cross-correlation property between the volume variables of adjacent lanes.
On analytic functions of bounded boundary rotation of complex order

The class V m ( b , δ ) of locally univalent functions f satisfying ∫ 0 2 π | Re [ 1 + 1 b z f ′ ′ ( z ) f ′ ( z ) ] − δ ( 1 − δ ) | d θ ≤ m π , where m ≥ 2 , δ ∈ [ 0 , 1 ) and b ≠ 0 (complex), is introduced. Some basic properties of this class such as distortion result, arc-length problem, and rate of growth of coefficients are studied. We also investigate the functions in V m ( b , δ ) under certain integral operators and also deal with some radii problems.
