Objectives The objective of this study is to determine if chronic infusion of arginine vasopressin (AVP) during mouse pregnancy recapitulates the human phenotypes of preeclampsia. We hypothesize a causative role of elevated AVP in the pathogenesis of preeclampsia. Methods Wildtype C57Bl/6J females were chronically infused with AVP (24 ng/h, s.c., or saline vehicle) before syngeneic mating. Systolic blood pressure during pregnancy was measured by tail-cuff plethysmography. Dams were placed in metabolic cages to collect 24 h urine samples at gestational day (GD) 17; and then sacrificed for necropsy at GD 18. Results In comparison to saline infused females, AVP infused females exhibited a pregnancy specific, significant increase in systolic blood pressure at GD 16 (110 ± 3 vs 120 ± 3 mmHg, p  Conclusions Chronic AVP infusion throughout pregnancy represents a novel, pregnancy specific, clinically relevant model of human preeclampsia that phenocopies all the cardinal physiologic, vascular, obstetric and immunologic phenotypes of human preeclampsia in mice.

Photocathode engineering for efficient photobioelectrochemical co2 reduction to formate

In this proposal, organic, carbon nanotubes fibres (CNTf) or reduced graphene oxide (RGO),and inorganic, p-type semiconductors or their nanocomposites, nanohybrids are systematically combined in multistep synthetic methods to fabricate novel photocathodes, as well as some counterparts of them (for the purpose of comparison), for studying their efficiency in a photoelectrochemical (PEC) for CO2 reduction to formate. One of the key elements of this hybrid photoelectrode is the presence of the enzyme formate dehydrogenase (FDH) anchored on a highly conductive carbon-based nanomaterial (CNTf or RGO) film at the top of the light absorber that catalyzes the reaction to reduce CO2 to formate. The carbon-based support will provide fast charge transfer from the semiconductor to the biocatalyst, without altering the FDH catalytic center. In other words, for ensuring electron transport between the two key photocathode components), in this project, a carbon nanotube fibre (CNF) or RGO interlayer film will be exploited between the photoactive material and FDH co-catalyst for the first time as a highly conductive platform, which is a prerequisite for technical applications to prevent short-circuiting and leaching of the biocatalyst or mediator species. After evaluation of their PEC activity, the relationship between their structure, synthesis method, and morphology on the one hand and their PEC activity on the another hand will be correlated and discussed. The aim will be selecting the best option as photocathode for designing a photoelectrochemical CO2 reduction reaction (PEC-CO2RR) cell with high efficiency and stability that can alleviate the pollution caused from fossil fuels use. In this way, the design of a photoelectrochemical CO2 reduction reaction (PEC-CO2RR) cell can be accomplished for producing formate, a valuable chemical product due to its wide range of applications.
Uncertainty analysis for rolling contact fatigue failure probability of silicon nitride ball bearings

Uncertainty analysis and parametric studies are presented for estimating the fatigue failure probability of surface cracks in silicon nitride ball bearings subjected to rolling contact fatigue. Uncertainty quantification of input parameters are presented first based on experimental data, inspection capability, and geometric reasoning. Surrogate models for equivalent stress intensity factors are then used for uncertainty propagation, which are built upon high fidelity finite element modeling with half-penny-shaped surface cracks. Instead of black-box type surrogate modeling, physical observations are employed to decompose the high dimensional surrogate model into multiple one-dimensional models. The cross-validation technique is used to find the best surrogate that has the smallest prediction variance. The probability of failure is estimated using Monte Carlo simulation and surrogate models. The parametric studies show that reducing the maximum crack size (by limiting inspection threshold) and increasing the fatigue threshold (by improving fracture toughness of a material) are the most effective ways of reducing the probability of failure. For example, decreasing the maximum crack size by 4.4% and increasing the lowest fracture threshold by 2.8% results in the reduction of probability of failure by 40%. Ball survivability increases with decreasing ball diameter, for a given peak Hertzian stress. In order to apply the current study to hybrid ball bearing design, the survivability results are generalized through non-dimensionalization.

Contextualizing in International Business research: Why do we need more of it and how can we be better at it?

Summary This paper joins the academic conversation about context and contextualization in Management and International Business (IB) research. I explain why it is both relevant and interesting to debate issues of context and contextualization and, as an IB scholar myself, I argue that while IB as a discipline can and should be at the forefront of meaningful contextualization of research, the current situation is that it is not. I maintain that we are much too often context-blind or blindfold ourselves intentionally against context. I advocate that there is no justification for this state of affairs and offer suggestions as to how we can improve the status quo. I propose that we are well equipped to conduct deep contextualization rather than merely study processes and phenomena across contexts. More specifically, I argue that we should include contextual attributes in our theorizing in a more direct manner, without fearing that causal explanation suffers from contextualization. I make the point that we will benefit from presenting and discussing our methodological choices as tough decisions based on multiple context-related criteria and that voicing context can help us to be stronger in selecting, employing and justifying our methodologies. I take issue with the fact that conducting IB research in research teams that transcend countries (and other contexts) does not, per se, guarantee that the team research is context-sensitive. Finally, I emphasize that it is meaningful and responsible to report context in a genuine manner as this helps to provide details that are relevant to understanding and trusting our findings even though it does not, in general, help in winning the academic publishing race.

Unbreakable heart: a reconfigurable and self-healing isolated dc/dc converter (u-heart)

Isolated dc/dc converters are increasingly employed as key components in data center, aerospace and electrical distribution, because of their capability to guarantee controllability and improve system efficiency despite power electronics is still more prone to failure with respect to other components of such systems. Fault-tolerant operation, when needed, is typically achieved through redundancy, which entails higher costs. The goal of U-HEART is to obtain fault-tolerant operation of the isolated dc/dc converter avoiding redundancy. This will lead to larger acceptance in industry, typically very skeptical when it comes to higher costs.  In 2017 we have applied for a patent  covering isolated dc/dc converters based on a multi-winding transformer, which can ride-through failures by means of the reconfigurability of the system and of the self-healing capacity of the cells. The hardware is reconfigurable because a part of the magnetic core with the associated winding and associated power module can be removed and self-healing because in case of a failure, the healthy part of the system realizes a different power converter function. The software will guarantee that the resulting dc/dc converter will be able to operate with one cell less or with its reconfigured version. The goal is that after a failure the overall system maintains the original functionality.
DYNAMIC RESOURCE ALLOCATION AND ACTIVE PREDICTIVE MODELS FOR ENTERPRISE APPLICATIONS

This work is concerned with dynamic resource allocation for multi-tiered, cluster-based web hosting environ- ments. Dynamic resource allocation is reactive, that is, when overloading occurs in one resource pool, servers are moved from another (quieter) pool to meet this demand. Switching servers comes with some overhead, so it is important to weigh up the costs of the switch against possible system gains. In this paper we combine the reactive behaviour of two well known switching policies – the Proportional Switching Policy (PSP) and the Bottleneck Aware Switching Policy (BSP) – with the proactive properties of several workload forecasting models. Seven forecasting models are used, including Last Observation, Simple Algorithm, Sample Moving Average, Exponential Moving Algorithm, Low Pass Filter and Autoregressive Moving Average. As each of the forecasting schemes has its own bias, we also develop three meta-forecasting algorithms (the Active Window Model, the Voting Model and the Selective Model) to ensure consistent and improved results. We show that request servicing capability can be improved by as much as 40% when the right combination of dynamic server switching and workload forecasting are used. As important is that we can generate consistently improved results, even when we apply this scheme to real-world, highly-variable workload traces from several sources.
Removal of benzene, toluene and xylene (BTX) from wastewater using immobilized modified prepared activated sludge (MPAS)

BACKGROUND
Improvements in biological oxidation approaches are required due to significant problems associated with this simple and commonly used approach. The work presents use of immobilized modified prepared activated sludge using modified polyvinyl alcohol (PVA)-alginate beads for removal of BTX and modifications based on the use of Fenton chemistry as pretreatment scheme.

RESULTS
Improved synthesis processes for immobilized sludge beads have been developed based on understanding the effect of PVA and alginate loadings. Stable beads with high levels of sludge activity were shown to give similar levels of COD removal efficiency compared with free sludge. In the case of Fenton pretreatment, 40 min of treatment was found to increase BOD5:COD value to about 0.31. Maximum COD efficiency of 93.1% was obtained using a biological process on a Fenton-treated sample which is significantly higher than that obtained with the untreated sample. The immobilized sludge was reused over nine batches without substantial loss in BTX degradation ability. Kinetic studies have also been presented.

CONCLUSION
An improved and promising approach for treatment of BTX containing wastewater with proven efficacy of the bioactivity and mechanical stability of the immobilized sludge, has been presented with better results based on Fenton pretreatment. © 2014 Society of Chemical Industry
Methods for forming rough ruthenium-containing layers and structures/methods using same

A method for forming a rough ruthenium-containing layer on the surface of a substrate assembly includes providing a ruthenium-containing precursor into the reaction chamber. A rough ruthenium layer may be deposited on the surface of the substrate assembly at a rate of about 100 Å/minute to about 500 Å/minute using the ruthenium-containing precursor. Further, a rough ruthenium oxide layer may be formed by providing a ruthenium-containing precursor and an oxygen-containing precursor into the reaction chamber to deposit the rough ruthenium oxide layer on the surface of the substrate assembly at a rate of about 100 Å/minute to about 1200 Å/minute. An anneal of the layers may be performed to further increase the roughness. In addition, conductive structures including a rough ruthenium layer or a rough ruthenium oxide layer are provided. Such layers may be used in conjunction with non-rough ruthenium and/or non-rough ruthenium oxide layers to form conductive structures. For example, such structures may be part of a capacitor structure, e.g., bottom electrode of a capacitor.
CABELOS CRESPOS, TRANÇAS E BLACK POWER: REFLEXÕES SOBRE O ADOECIMENTO DE MULHERES NEGRAS, AUTOESTIMA E EMPODERAMENTO

Racism is perpetrated by colonialism and it is full of violence, oppression, exploitation.It remains in society by new colonialities in social structure.Since early childhood, black women have their identity denied by historically, constructed standards wich, over their life, produce self-denial and "not-self".Hair straightening is the expression of a racist social process.Hair transition and self-discovery through the acceptance of own hair mark the rupture of aesthetic standards, self-appreciation and promoting the afro-Brazilian culture.Through "writing-experience" [escrevivência] and narratives of a master's research, the authors discuss afro-Brazilian hair since inferiorization to empowerment.They discuss how mental suffering like trauma defines black women's not-belonging into the white world and hair transition as self-care, selfesteem and foremost, belonging to the black perspective.
A novel vascular clip design for the reliable induction of 2-kidney, 1-clip hypertension in the rat

The 2-kidney, 1-clip (2K1C) model has provided many insights into the pathogenesis of renovascular hypertension. However, studies using the 2K1C model often report low success rates of hypertension, with typical success rates of just 40–60%. We hypothesized that these low success rates are due to fundamental design flaws in the clips traditionally used in 2K1C models. Specifically, the gap widths of traditional silver clips may not be maintained during investigator handling and these clips may also be easily dislodged from the renal artery following placement. Therefore, we designed and tested a novel vascular clip possessing design features to maintain both gap width and position around the renal artery. In this initial study, application of these new clips to the left renal artery produced reliable and consistent levels of hypertension in rats. Nine-day application of clips with gap widths of 0.27, 0.25, and 0.23 mm elicited higher mean arterial blood pressures of 112 ± 4, 121 ± 6, and 135 ± 7 mmHg, respectively ( n = 8 for each group), than those of sham-operated controls (95 ± 2 mmHg, n = 8). Moreover, 8 out of 8 rats in each of the 0.23 and 0.25 mm 2K1C groups were hypertensive, whereas 7 out of 8 rats in the 0.27 mm 2K1C group were hypertensive. Plasma renin concentrations were also increased in all 2K1C groups compared with sham-operated controls. In summary, this novel clip design may help eliminate the large degree of unreliability commonly encountered with the 2K1C model.
Technology for the reuse of brines from reverse osmosis

USEFUL WASTES is a new company that has developed an innovative technology that allows the complete reutilization of brines from reverse osmosis process in food industry, transforming this waste into different valuable byproducts.

Reverse osmosis is widely used to treat water in food industry due to the water quality requirements when it is used to clean, freeze or cook food, obtaining 75% of high quality water and 25% of brine that is discarded.

With the aim of reducing this waste of water USEFUL WASTES was founded in 2016, and its main strengths are:

- Improvement in water production, from the current 75% to 95-97%;
- Circular economy: the remaining 1% is transformed into different valuable byproducts, such as bleach, salts or hydrogen gas;
- Bleach self-production: this product is massively used in the food industry for cleaning and disinfection. Its production as a byproduct will allow the company not only to reduce costs but also to not be dependent on bleach suppliers.

But most of all, the main advantage of USEFUL WASTES that guarantees its success is that it is profitable. Operating costs are smaller than the cost associated to bleach purchase (estimated savings are 4c€ per litre), without taking into account the savings obtained in water supply (22-24% of water that was being discarded is now transformed into fresh and soft water).

Regarding the main competitors, brine management sector is completely dedicated to solving the problem caused by desalination plants’ brines, potentially dangerous for the marine ecosystems where they are discharged due to its high content in nitrates, so there are no solutions in the market targeting food industry.

During phase 1, USEFUL WASTES will elaborate a detailed business plan which will set the strategy to commercialize successfully
its innovation all over Europe.
The impact of population aging on public finance in the European Union

Population aging is a process that shapes the economic environment in most of the developed economies. Thus, understanding the dynamics between public finance and the demographic variables enables policy-makers to adapt and to ameliorate their medium-term budgetary frameworks. The aim of this paper is to examine the fiscal implications of the demographic shift using panel data on 25 EU countries in the period from 1995 until 2014. In order to qualify the findings of previous literature, this paper considers the demographic variables as endogenous and applies the system GMM estimator to obtain the elasticity of several public finance categories with respect to population aging. The results indicate significant and positive impacts of the elderly share on expenditure for pensions and social protection. The higher positive impact on overall public expenditure compared with total government revenue confirms the negative effect of population aging on budget balance. An increase in the young population has a significant impact only on health expenditure.
Density and temperature reconstruction of a flame-induced distorted flow field based on background-oriented schlieren (BOS) technique

An experimental system based on the background-oriented schlieren (BOS) technique is built to reconstruct the density and temperature distribution of a flame-induced distorted flow field which has a density gradient. The cross-correlation algorithm with sub-pixel accuracy is introduced and used to calculate the background-element displacement of a disturbed image and a fourth-order difference scheme is also developed to solve the Poisson equation. An experiment for a disturbed flow field caused by a burning candle is performed to validate the built BOS system and the results indicate that density and temperature distribution of the disturbed flow field can be reconstructed accurately. A notable conclusion is that in order to make the reconstructed results have a satisfactory accuracy, the inquiry step length should be less than the size of the interrogation window.
