Planet rolling bearing with advanced technologies

The development of Ultra High Propulsive Efficiency (UHPE) engine is a key factor to fulfil the main milestones of the Sustainable And Green Engines (SAGE) program: high environmental benefits of UHPE will be reached through a power gearbox decoupling fan and turbine speeds.
Such innovation raises different technological challenges: the increase of the rotational speed and harsh lubrication conditions due to the centrifugal field. In terms of power gearbox performance and reliability, the design and lubrication of the rolling bearings, crucial components, can affect the gearbox and engine architectures.

The scope of PROBATE is “to predict bearing behaviour (through dynamic, lubrication & thermal coupled modelling) and develop various planet rolling bearing technologies, overcoming current design rules of aero-engine bearings enabling the development of a UHPE engine”. Specific objectives are:
- To develop a new numerical model able to predict heat generation and transfer in the planet bearing taking into account interactions between dynamics, lubricant and thermal behaviours
- To develop an optimized profile ceramic roller, a specific polymer cage design and an optimized lubrication solution as well as their integration in the new planet bearing
- To demonstrate -30% in power loss & oil flow and -15% of the bearing weight in comparison to the current baseline solution & increasing at the same time the reliability.

To demonstrate their enhanced performances, the PROBATE new bearing technologies will firstly assessed through modelling and then tested with elementary and sub-scale testing. The gained knowledge will enable the transfer and exploitation of projects results to the industrial field by providing analysis tools and new design rules.
SKF AERO-BV-ENGINE have well-known high-level engineering capabilities in the aerospace filed, performance test facilities and manufacturing units necessary to develop a new advanced bearing technology for future UHPE engine.

Isorhamnetin flavonoid synergistically enhances the anticancer activity and apoptosis induction by cis-platin and carboplatin in non-small cell lung carcinoma (NSCLC).

The development of novel antitumor drugs for the treatment of non-small cell lung carcinoma NSCLC is imperative in order to improve the efficacy of lung cancer therapy and prognosis. In the current study, we demonstrated the antitumor activity of isorhamnetin and its combinations with cisplatin and carboplatin against A-549 lung cancer cells. In order to assess the anticancer enhancing effect of isorhamnetin on cisplatin and carboplatin, A-549 cells were treated with isorhamnetin, cisplatin, carboplatin and their combinations and cell viability, cell apoptosis, cell cycle arrest as well as loss of mitochondrial membrane potential were evaluated by MTT assay, flow cytometry, confocal microscopy and fluorescence microscopy. The effect of the drugs on cancer cell migration, microtubule depolymerization as well activation of caspases was also studied. The results revealed that, as compared to single drug treatment, the combination of isorhamnetin with cisplatin and carboplatin resulted in greater effect in inhibiting cancer cell growth and inducing apoptosis. Combination of isorhamnetin with cisplatin and carboplatin resulted in more potent apoptosis induction as revealed by fluorescence microscopy using AO/PI double staining. Isorhamnetin and its combinations also triggered microtubule distortion and depolymerization. The combination of isorhamnetin with cisplatin and carboplatin increased the number of cells in G2/M phase dramatically as compared to single drug treatment. Moreover, isorhamnetin and its combinations with known anticancer drugs induced disruption of the mitochondrial membrane potential as well as activation of caspases 3, 9 and poly-(ADP-ribose) polymerase in A-549 cells. Isorhamnetin as well as its combinations with cisplatin and carboplatin resulted in inhibition of cancer cell migration significantly. Results of the current study suggest that isorhamnetin combinations with cisplatin and carboplatin might be a potential clinical chemotherapeutic approach for NSCLC.
Strongly correlated phenomena in twisted bilayers of graphene and transition metal dichacogenides

Fundamental properties of 2D materials are dramatically modified when they are brought next to each other to form a vertical heterostructure. Then, the combination of the 2D layers as well as the relative orientation between them ultimately determines the performance of the new hybrid material. This presents tremendous new opportunities for manipulating the behaviour of 2D layered materials and ultimately achieving unprecedented control over their performance when integrated into highly specific functional devices.
However, research in this field is in its nascent stage and many exciting phenomena remain to be discovered. The main objective of TWISTM is to unravel the most fundamental properties of unexplored graphene- and transition metal dichalcogenide-based bilayers arising from many-body interactions. Progress here requires of a comprehensive microscopic picture of the fundamental properties of the heterostructures in clear connection to their macroscopic behaviour. TWISTM will tackle this challenge by using local probe techniques (STM and s-SNOM) with sub-nm resolution combined with mesoscopic electron transport measurements on in-house engineered twisted bilayers with accurate misalignment angles. TWISTM comprises three goals: i) to develop and optimize a fabrication method towards the achievement of high-quality twisted bilayers, ii) a multiscale search for collective electronic and optical phenomena arising from the coupling between the layers; iii) A full characterization of the superconducting and magnetic properties as a function of the chosen materials combination and twist angle. Overall the project aims at acquiring fundamental scientific knowledge with potential for technological applications that will be useful in both academia and industry. Furthermore, TWISTM will offer high-quality interdisciplinary training to a young researcher helping her to develop a promising independent scientific research career as well as her own scientific network.
Energy considerations for frictional impacts

Many machine and mechanism processes are accompanied by impacts with friction. They arise by short-time contacts between two or more bodies, and they generate energy losses mainly due to friction in tangential contact directions. During the last two decades, a couple of impact models based on the theory of rigid body contact were established connected with the names of Moreau, Fremond, and Glocker, which all work quite satisfactorily with respect to practical applications, although some examples indicate deviations requiring more investigations with respect to the impact models and the type of examples considered. We shall focus on Glocker’s model, for which some experimental verifications are available by Beitelschmidt. A missing link are energy considerations, which are available, but nevertheless do not provide us with a complete information for all possible cases. The paper tries to fill a bit this gap by founding the investigations on a combined phenomenological and theoretical basis.
METHOD OF SPINNING FIBRES OR EXTRUSION, AND THE PRODUCTS OBTAINED

The invention relates to a continuous, scalable and parallelizable method for preparing strong and stiff fibres (filaments) or films. The fibre or film is prepared by utilizing hydrodynamicaily induced alignment of the constituents of a dispersion in combination with surface-charge controlled gel transition to produce fibres with a high degree of alignment of the constituents (polymer(s), fibrils etc). The invention also relates to the fibres or films so formed.
CROSSED TIES FOR CONSTRUCTION BLOCK ASSEMBLY

An assembly of interconnected blocks such as lightweight concrete, rock, or wood blocks, in combination with crossed ties means used for attaching blocks two by two while keeping them in a stable spaced apart position. The crossed ties comprise a rectangular shape wherein opposite corners are joined by straight links which resist shear forces due to wind, storm, tornadoes, landslides or earthquake. They comprise furthermore pegs which attach the blocks two by two when pressing pegs into notches dug on upper or lower surfaces of the blocks or on their sides. The blocks are then made with notches on upper or lower surfaces of the blocks, and on their sides, which correspond to positions of pressing pegs, to interconnect blocks together. Such pegs are provided to mesh with critical positions in the blocks for stable junctions.
Performance measures as forms of evidence for science and technology policy decisions

Amidst current widespread calls for evidence based decision making on public investments in science and technological innovation, frequently interpreted to imply the employment of some bundle of output, outcome, productivity, or rate-of-return measures, the promises and limitations of performance measures, singly or collectively, varies greatly across contexts. The promises reflect belief in, scholarly research supportive of, and opportunistic provision of performance measures that respond or cater to executive and legislative branch expectations or hopes that such measures will facilitate evidence-based decision-making. The limitations reflect research on the dynamics of scientific discovery, technological innovation and the links between the two that even when well done and used by adepts, performance measures at best provide limited guidance for future expenditure decisions and at worst are rife with potential for incorrect, faddish, chimerical, and counterproductive decisions. As a decision-making enhancement, performance measurement techniques have problematic value when applied to the Big 3 questions of U.S. science policy: (1) what is the optimal size of the Federal government’s investments in science and technology programs; (2) the allocation of these investments among missions/agencies/and programs (and thus fields of science); and (3) the selection of performers, funding mechanisms, and the criteria used to select projects and performers.
First description of the nest and eggs of Ceará Leaftosser Sclerurus cearensis, with a review of the breeding biology of genus Sclerurus

Sclerurus is a genus of morphologically uniform, strict understorey, leaf litter specialists. We present the first description of the nest and eggs of Ceará Leaftosser S. cearensis from north-east Brazil and review breeding data for the genus. Based on three nests, the nest of S. cearensis was classified as cavity/with-tunnel/low cup, the type typical of the genus. The nests were excavated in banks at a mean height of 1.48 ± 0.22 m above ground. Tunnels measured 50.83 ± 4.25 cm and terminated in an expanded, globular chamber where a small cup of sticks harbours the two white eggs. Eggs at one nest measured 25.7 × 19.8 mm and 24.3 × 19.6 mm, and weighed 5.1 g and 4.5 g, respectively. Available breeding data for the genus Sclerurus are remarkably uniform in all aspects and match our observations of Ceará Leaftosser.
Necl-5/PVR enhances PDGF-induced attraction of growing microtubules to the plasma membrane of the leading edge of moving NIH3T3 cells

Microtubules (MTs) search for and grow toward the leading edge of moving cells, followed by their stabilization at a specific structure at the rear site of the leading edge. This dynamic re-orientation of MTs is critical to directional cell movement. We previously showed that Necl-5/poliovirus receptor (PVR) interacts with platelet-derived growth factor (PDGF) receptor and integrin α(v) β(3) at the leading edge of moving NIH3T3 cells, resulting in an enhancement of their directional movement. We studied here the role of Necl-5 in the PDGF-induced attraction of growing MTs to the leading edge of NIH3T3 cells. Necl-5 enhanced the PDGF-induced growth of MTs and attracted them near to the plasma membrane of the leading edge of NIH3T3 cells in an integrin α(v) β(3) -dependent manner. Furthermore, Necl-5 enhanced the PDGF-induced attraction of the plus-end-tracking proteins (+TIPs), including EB1, CLIP170, an intermediate chain subunit of cytoplasmic dynein, and p150(Glued) , a subunit of dynactin, near to the plasma membrane of the leading edge. Thus, Necl-5 plays a role in the attraction of growing MTs to the plasma membrane of the leading edge of moving cells.
Internal jugular vein reflux in patients with transient global amnesia: a meta-analysis of case–control studies

Our aim was to quantitatively evaluate the role of internal jugular venous reflux (IJVR) in transient global amnesia (TGA). Meta-analysis of case-control studies was conducted using Medline, Current contents connect, ISI Web of Knowledge, Biological abstracts and Scopus, plus citations of selected studies. We performed sensitivity and subgroup analyses to assess the effect of methods of IJVR determination, blinding of studies, and definition of IJVR on the results. Seven studies were included in the first meta-analysis which investigated the frequency of IJVR in 312 patients and 261 controls. IJVR was more common in patients (OR 5.867, 95% CI 3.895-8.838,). Meta-analysis of blinded studies did not alter our results (OR 10.894, 95% CI 5.396-21.996). Another meta-analysis with seven studies was performed in which, IJVR was more frequent in patients with TGA and precipitating factors compared with those without any identifiable precipitating factors (OR 2.889, 95% CI 1.748-4.777). IJVR is a risk factor for TGA. However, not all patients with history of TGA spells had IJVR and this, together with higher frequency of IJVR in patients with TGA who experienced precipitating events, showed the need of considering several other factors in further primary researches.
Next generation bio-butanol

Biobutanol is an attractive commodity chemical and advanced biofuel with superior properties but the 1st gen process suffers from technical and economical constraints. ButaNexT project aims to overcome some of those technical barriers through a novel combination of innovations. Individual stages of the process supply chain will be developed, validated and optimized at lab-scale and then integrated and demonstrated at pilot scale. A holistic approach is proposed to produce cost-competitive biobutanol from 3 types of lignocellulosic biomass and waste in a sustainable way being flexible to accommodate regionally specific feedstocks.
Project exploitable outputs include:
(1)novel low CAPEX two-step pretreatment process that releases hemicellulose and cellulose from recalcitrant feedstocks for further enzymatic and/or fermentation processing,
(2)new tailored enzyme cocktail yielding highly fermentable sugars at low enzyme dosages and lower cost,
(3)superior clostridial strains with enhanced production characteristics i.e. butanol and inhibitor tolerance,
(4)high productivity fermentation process including a novel in-situ product recovery step. 
Technology advances allow sustainable feedstock diversification, improve conversion yields and efficiency, reduce energy requirements, and water usage. We expect significant reductions in cost (target $800/T which equates to 50% of current 1st gen solvent production in China) as well as enhanced energy balances and reduced GHG emissions vs 1st gen biofuel production (target a 85% reduction).
The project output (a technically and economically-validated process) will provide the EU with a tremendous opportunity to build an advanced biofuel business from sustainable feedstocks. This is strategically important to contribute to the European 10% target for renewable transportation fuels for 2020.
The proposed project fits into the topic ”Developing next generation technologies for biofuels and sustainable alternative fuels” (LCE-11-2014)
The no-load vacuum eutectic solder die bonding process

Eutectic soldering process usually takes with the load own gravity to provide downward force of the chip, the chip closer Solder Lug and die-attach area contact, which inevitably load in with the surface of the chip, either point or face contact has placed enormous demands on the cleanliness of the chip surface. however the silicon powder will lead to damage chip in the role of load, and the load surface is easy to stain, lower the yield of eutectic soldering, and very high chip cleanliness is required. Through improve temperature curve and pressure control to achieve a no-load vacuum eutectic soldering die bonding process. Temperature curve can be improved to achieve uniform welding, in order to reduce the voids, make the die-bonding flat, and also need to introduce air pressure control technology to improve the vacuum eutectic soldering quality and product yield. Pressure, atmosphere control method refers to a chip provides a downward pressure through the internal pressure changes to achieve a no-load process. At present, this process has been put into production use for almost a year, all products yield remained at 99.8%, die shear strength are greater than 2 times the standard, the voids rate <;5%, while saving the cost of briquette production significantly improved production yield.
"Multinational Corporations, Self-Interest, and the Neglected Role of Empathy"

The neoclassical school has long promoted the pursuit of self-interest as a central tenet of the theory of the firm, a position justified with excerpts from Adam Smith’s The Wealth of Nations (1776) that suggest self-interest leads to a maximization of net social welfare. In this article, we contend that in a modern context where large multinational corporations (MNCs) dominate the global business environment, crucial relational elements of Smith’s thinking have been lost. More specifically, we argue that Smith’s proverbial butcher, brewer, and baker knew their stakeholders’ faces, which aroused empathy that influenced the businessperson’s considerations of self-interest and better aligned them with social welfare. However, employees of modern-day MNCs seldom directly interface with their many stakeholders, which diminishes the link between self-interest and social welfare. To illustrate this point, we compare an approximation of Smith’s small baker, Bloedow’s Little Bake Shop, with a large MNC bakery, General Mills. Through this comparison, we propose that theories of management can be made more reasonable when they consider the role of empathy in conjunction with self-interest and that the likelihood of promoting social welfare increases when the empathy of the MNC employees is aroused.
The Effects of Multiple Dimensions of Residential Segregation on Black and Hispanic Homicide Victimization

Past research examining the association between residential segregation and homicide victimization has often considered only one dimension of segregation, and the literature that does use a multidimensional approach has not presented a uniform set of findings. The majority of the studies have focused on the experiences of Blacks, while overlooking the possibility that the differences between the structure of Black and Hispanic communities may alter the conclusions for Hispanics. In this study, we argue that in order to understand the mechanisms underlying the effects of segregation on homicide, we need to understand the multidimensional structure of Black and Hispanic segregation, and examine whether the relationship between segregation and homicide differs for Blacks and Hispanics. Using 2000 census data and homicide data from the National Vital Statistics System (1999–2001) for U.S. metropolitan areas, we identify two empirically distinct superdimensions of segregation (group separateness and centralized concentration), both of which have a substantial positive and statistically significant impact on homicide victimization for both Blacks and Hispanics.
DETECTION AND CALCULATION OF HEART RATE RECOVERY IN NON-CLINICAL SETTINGS

A wearable device measures heart rate recovery of a user in a non-clinical setting. The wearable device comprises a heart rate detector configured to detect heart rate data of the user, an activity sensor configured to detect motion of the user, and a processor. The processor is configured to identify a start of an activity by the user using the motion detected by the activity sensor. Responsive to detecting the start of the activity, the processor monitors the motion detected by the activity sensor to identify an end of the activity. A regression analysis is performed on heart rate data detected by the heart rate detector during a period of time after the end of the activity, and the heart rate recovery of the user is determined using the regression analysis.
Managing Information for a Risk Based Approach to Stakeholder Management

This paper proposes a risk based approach in order to obtain a quantitative estimate of the salience of the stakeholders involved in a project. The integration between stakeholders and risk management processes in the Project Management System allows us to realize a twofold objective: a quantitative estimate of the salience of each stakeholder in terms of the contribution to the overall project riskiness and an identification of the most effective responses as a function of the dynamics of the risks generated by each stakeholder. The proposed approach has been applied to an international project concerning the building of a pipe line.
