Planning pour la thérapie de tumeur du foie par ultrasons haute intensité

Dans le contexte general des therapies minimalement invasives, les travaux de cette these portent sur le planning d'une therapie interstitielle de tumeurs du foie par ultrasons haute intensite. Dans un premier temps, une caracterisation des structures anatomiques hepatiques a partir de donnees scanner X est proposee selon deux methodes de segmentation basee sur le graph cut : l'une semi-interactive et rapide pour extraire le foie et les eventuelles tumeurs ; et l'autre automatique et specifique a la segmentation de la vascularisation hepatique par l'introduction d'un a priori local de forme estime a partir de moments geometriques 3D. La seconde partie de cette etude est consacree a la modelisation des effets de la therapie sur les tissus. Le modele propose offre la possibilite de simuler differents types de sonde composee d'une matrice d'elements controlables en phase et intensite. La description de la vascularisation locale dans le milieu peut egalement etre integree dans le modele. Les travaux et resultats obtenus portent sur trois aspects et/ou applications de ce modele : 1) une methode pour accelerer la resolution de la BHTE sous certaines hypotheses, 2) des resultats preliminaires de modelisation d'une sonde 64 elements a focalisation dynamique et 3) le design geometrique d'une sonde endocavitaire 256 elements.
Optimization of the Carbon Coating of Honeycomb Cores for Broadband Microwave Absorption

A simple and fast coating method of honeycomb cores for microwave absorption has been described. The honeycomb cores with two different thicknesses (5 and 20 mm) coated with thermoplastic resin filled with carbon powder as lossy filler in 5, 10, 15, and 20 wt% have been tested for microwave absorption in 2 - 18-GHz frequency range. The 5-mm-thick honeycomb has shown absorption bandwidth of 14 GHz for maximum absorption of -6 dB (75%) with 15 wt%. filler content. However, the percentage of the filler was decreased to 10 wt% in 20-mm-thick honeycomb absorber for maximum absorption over a wide frequency range. The honeycomb sample with 10 wt% filler has bandwidth of 18 GHz for -7 dB (80%) reflection loss. The reflection loss measurements of coated honeycomb cores have also shown that use of E-glass fiber/epoxy composite can enhance the performance of the honeycomb absorber. The combination of a microwave absorbing nanocomposite and the coated honeycombs has been resulted in inferior absorption properties in 2 - 18-GHz frequency range.
[Study on effect and mechanism of liuwei dihuang decoction in modulating hypothalamus-pituitary-ovary axis in senescence accelerated mice model].

OBJECTIVE To study the changes of hypothalamus-pituitary-ovary (HPO) axis of senescence accelerated mice (SAM) model in their aging process and the modulatory effect of Liuwei Dihuang decoction (LW) on the changes. METHODS Using vaginal smear to test the estrous cycle of animal; using radioimmunoassay to determine serum levels of estradiol (E2), and beta-endorphin (beta-EP) and substance P (SP) in hypothalamus; and the western bloting technique was adopted to quantify the level of luteinizing hormone (LH) in pituitary and estradiol receptor alpha (ER alpha) in pituitary and ovary. RESULTS The estrous cycle and diestrus were significantly prolonged as SAMP8 aged, the concentration of serum E2 was lower, pituitary LH was higher in the SAMP8 than those in SAMR1. Content of beta-Ep and SP in hypothalamus gradually lowered during aging, SP content lowered after a transient increasing, and ER alpha expression lowered significantly. LW could significantly shorten the diestrus, increase weight of ovary, elevate serum E2 level, significantly reduce the LH level in pituitary, increase beta-EP content in hypothalamus and ER alpha expression in ovary, but significantly lower SP content in hypothalamus. Oral administration of estrogen could increase serum E2, beta-EP and SP content in hypothalamus and ER alpha expression in pituitary, but lower LH level in pituitary, weight of ovary and ER alpha level in ovary. CONCLUSION SAMP8, in the aging process, develops a progressive HPO axis functional disturbance, it is closely related with the change of levels of peptide neuro-mediator in hypothalamus and change of ER alpha level in ovary. LW could improve or modulate the HPO axis functional disturbance in SAMP8.
Individualized Considerations Regarding Sub-Superficial Musculoaponeurotic System Facelift Techniques

Since the introduction of the technique reported by Skoog [1] and the study of Mitz and Peyronie [2] regarding the superficial musculoaponeurotic system (SMAS), the concept of facial rejuvenation has entered a new phase, going beyond the conventional subcutaneous facelift technique. However, Mitz and Peyronie [2] focused on the SMAS layer lateral to the zygomaticus major muscle—in other words, the lower face. In response to the development of the SMAS technique for facial rejuvenation, the emphasis in the approach to the lower face including the lateral neck has changed accordingly, recently being referred to as cervicofacial rhytidectomy. Cervicofacial rhytidectomy may offer successful lower cheek and jawline rejuvenation, but shows less success for rejuvenation of the malar region and of the infraorbital area medial to the zygomaticus major muscle. When using this technique, due to poorly balanced descent of the untouched malar area, a well-rejuvenated lower face will appear dissonant with the malar region over the years. Remnants of the dissonance may sometimes be noticeable, and this is called a lateral sweep deformity. In an effort to overcome the problem posed by lateral sweep deformities, facial rejuvenation techniques have evolved to focus on various sub-SMAS facelift methods. The evolution of facial rejuvenation surgery reflects recent innovations in the detailed understanding of the retaining ligament, as described by Furnas [3] and Stuzin et al. [4], and has been further improved by a sophisticated theoretical approach to the midface and periorbital region [5-9]. The most commonly adopted techniques may be the composite facelift described by Hamra [5,6], the extended SMAS technique developed by Stuzin et al. [4], the high SMAS technique proposed by Barton [8], and the subperiosteal facelift developed by Ramirez et al. [7]. Since each technique has specific advantages and disadvantages, we believe that proper indications must be identified for Joo Heon Lee, Won Suk Oh, Sung Wan Park, Jin Woo Song, Jae Hoon Kim
The impact of refugees on the labour market: a big splash in a small pond? CEPS Working Document No 2018/07, October 2018

What impact will recently arrived refugees have on the labour markets of receiving European countries? As a contribution to the debate, this paper looks at the composition of recent refugee inflows and reviews the relevant characteristics of EU labour markets. Even in the most affected member states, the number of refugees recognised between 2014 and 2017 is small relative to the total population. The potential impact on aggregate wages or on the unemployment rate is therefore not expected to be economically significant. However, many of the recent refugee cohorts in these member states were young low-skilled men. The 2014-17 inflow is thus sizeable relative to the population of this specific group. The authors of this paper highlight two potential challenges associated with such a concentrated inflow. First, since young low-skilled men are already an economically vulnerable group, higher competition for jobs can further increase this vulnerability and fuel negative (antiimmigrant) sentiment. Second, the labour market sectors relevant for many refugees already face uncertain labour demand due to import competition and continuing technological change. The authors find that this challenges the medium- and long-term prospects for the integration of refugees. It also calls for attention to be paid to training and upgrading their skills. At the same time, efforts to integrate newcomers should go hand in hand with the better economic inclusion of other vulnerable population groups.
Classifying Sensors Depending on their IDs to Reduce Power Consumption in Wireless Sensor Networks

Wireless sensor networks produce a large amount of data that needs to be processed, delivered, and assessed according to the application objectives. Cluster-based is an effective architecture for data-gathering in wireless sensor networks. Clustering provides an effective way for prolonging the lifetime of a wireless sensor network. Current clustering algorithms usually utilize two techniques, selecting cluster heads with more residual energy and rotating cluster heads periodically, in order to distribute the energy consumption among nodes in each cluster and extend the network lifetime. Clustering sensors are divided into groups, so that sensors will communicate information only to cluster heads and then the cluster heads will communicate the aggregated information to the processing center, and this may save energy. In this paper we show Two Relay Sensor Algorithm (TRSA), which divide wireless Sensor Network (WSN) into unequaled clusters, showing that it can effectively save power for maximizing the life time of the network. Simulation results show that the proposed unequal clustering mechanism (TRSA) balances the energy consumption among all sensor nodes and achieves an obvious improvement on the network lifetime.
The effect of starvation on the immune response of chickens.

SUMMARY The effect of food and water deprivation on the number of antibody-producing spleen cells and on the rate of clearance of bacteria by the reticuloendothelial system was studied in 5-week-old cross-bred (White Leghorn X Rhode Island Red) chickens. Fortyeight hours of deprivation of food and water resulted in decreased hemagglutinating antibody titer and decreased antibody-producing cells in the spleens of chickens immunized with sheep red blood cells. Deprivation of food and water also slowed bacteria clearance rate from the circulation.
with respect to the “ Lebesgue ” measure on

We study a class of Piecewise Deterministic Markov Processes with state space R d × E where E is a finite set. The continuous component evolves according to a smooth vector field that is switched at the jump times of the discrete coordinate. The jump rates may depend on the whole position of the process. Working under the general assumption that the process stays in a compact set, we detail a possible construction of the process and characterize its support, in terms of the solutions set of a differential inclusion. We establish results on the long time behaviour of the process, in relation to a certain set of accessible points, which is shown to be strongly linked to the support of invariant measures. Under Hörmander-type bracket conditions, we prove that there exists a unique invariant measure and that the processes converges to equilibrium in total variation. Finally we give examples where the bracket condition does not hold, and where there may be one or many invariant measures, depending on the jump rates between the flows.
THE EFFECT OF BRAND REPUTATION, PRODUCT RELIABILITY, PRICE AND BRAND ADMIRATION ON PURCHASING DECISION (Study on Food Products that Sold through Instagram at Semarang)

Development in technology was really fast, especially in the information and telecommunications field. Nowadays, technology cannot be replaced by human life. Social media is very important to various business and personal life. Social media helping us to find new colleagues and help us to easier get information. For many years, most powerful social media are Facebook, Twitter, and LinkedIn. But for this past years, Instagram can take market attention. Due to a number of followers, culinary became favorite on Instagram. Before that, culinary products rarely marketed on other social media including Facebook. In this study, research will be focused on the kind of food that can be delivered in Semarang. This research will be started by sharing questionnaires to 157 respondents. Those respondents already have experience in buying food from Instagram in Semarang. From the result, two hypotheses accepted. The first one concluded there is a positive impact from brand reputation to buying decision. The second one concluded there is a positive impact on brand admiration to brand reputation. For reliability and product price didn’t give impact for buying decision.

Dynamic Differential Evolution with Difference Mean Based Perturbation

Optimization in a dynamic environment is a real challenge owing to the multimodality, high complexity, and ruggedness of the functions involved. Tracking the global optima in such a dynamically changing landscape is called Dynamic Optimization Problem(DOP). This paper aims at modifying the popular DOP handling technique Dynamic Differential Evolution( DynDE) by introducing a unique scheme named Difference Mean Based Perturbation (DMP) technique apart from classical DE that greatly enhances the diversity of the algorithm and offers a scope of thorough search of area in the vicinity of the current best. The proposed algorithm is hence addressed as DynDE-DMP. The other features of DynDE-DMP include an aging mechanism, an exclusion principle and a cluster based retention strategy. Performance of DynDE-DMP has been tested over the suite of benchmark problems used in Competition on Evolutionary Computation in Dynamic and Uncertain Environments, held under the 2009 IEEE Congress on Evolutionary Computation (CEC) and compared with six state-of-the-art EAs. The comparison results reflect the effectiveness of the DMP scheme thus establishing the proposed approach, a successful optimizer in Dynamic Environments.
The Effect of External Sourcing on The Financial Performance of Manufacturing Companies Listed in Indonesia Stock Exchange (BEI)

There were differences in research results of several previous studies which examined the relationship between external sourcing and corporate financial performances. Those results indicated that external sourcing could have a positive, negative, or no effect on the financial performance of the company. There was numerous literature stated that external sourcing was a strategy to minimize costs which could reduce production and procurement costs, thus becoming a strategy considered by the top management to improve the company performance. This study analyzed the external sourcing effects on financial performance (ROA) of manufacturing company listed in Indonesia Stock Exchange (BEI). Total population of manufacturing companies listed in the Indonesia Stock Exchange from 2012-2016 was as many as 132 companies, but there were only 70 companies that met the criteria to be the object of the research. The manufacturing company used three industry sectors namely basic and chemical industry, consumer goods industry, and miscellaneous industry as the research objects. Using panel data regression, the research results indicated that external sourcing strategy had a significant and negative effect on ROA. Negative effects resulting from purchases on external parties (external sourcing) were caused by the high cost of sales exceeded the company revenue. Therefore, the company should pay attention to the level of purchases made, namely purchases to the third party on raw materials and goods in the process to have the level of purchases at an optimal point in order to generate profits for the company.

Youth Participation University in Tax Advice via the Learning Service

Taxation is one of the main sources of income of a country. When the government wants to increase the economic and social development of its country, it is necessary to raise tax rates on the tax base. However, it becomes complicated when the informality of the economically active population has remained at around 45%, as is the case of Ecuador, and the people who are forced to pay these taxes mostly have questions or unaware of it. For this reason, the Politecnica Salesiana University decided to sign an agreement with the Internal Revenue Service so that accounting students could provide tax advice in solidarity to taxpayers who have questions in their tax return forms. This article analyses the development of the office of voluntary taxpayer assistance implemented in the university, and how service learning influenced students and 250 taxpayers in the sector. Also, suggestions to other universities to implement a similar programme are provided.
Interaction of monocytes and T cells in the regulation of normal human megakaryocytopoiesis in vitro: role of IL‐1 and IL‐2

Summary. Autologous or allogeneic peripheral blood T cells can stimulate the human megakaryocyte progenitor cell (CFU‐Meg)‐derived colony formation in a dose‐dependent fashion in agar cultures of nonadherent (NA), T cell‐depleted (NT) bone marrow (BM) cells. Low concentrations of monocytes and T cells can collaborate in the stimulation of CFU‐Meg colony formation or in the production of megakaryocyte colony stimulating factor (Meg‐CSF) by T cells in the presence of mitogens or IL‐2. Monocytes alone can produce only negligible Meg‐CSF under any conditions. When monocyte conditioned medium (CM) was added to T cell‐stimulated NA, NT BM cell cultures, CFU‐Meg colony growth was appreciably increased compared with that stimulated by T cells alone. Dose‐dependent increase in CFU‐Meg colony growth was noted when varying concentrations of IL‐1 were added to T cell‐stimulated NA, NT cell cultures, although IL,‐1 itself could support no CFU‐Meg colony growth in the absence of T cells. These data suggest that a synergistic interaction between T cells and monocytes during the production of Meg‐CSF by T cells could be partly mediated by IL‐1. IL‐2 was found to stimulate Meg‐CSF production by T cells in the presence or absence of mitogens. IL‐2‐stimulated Meg‐CSF production by T cells was augmented by the addition of monocytes. Although IL‐2 itself had no stimulatory effect on CFU‐Meg colony growth, dramatic augmentation in the CFU‐Meg colony number was noted when IL‐2 was added to T cell‐stimulated NA, NT cell cultures. High concentrations of monocytes and prostaglandin E (PGE) inhibited the CFU‐Meg colony formation. These results suggest that IL‐1 and IL‐2 may play a stimulatory role on the normal human in vitro megakaryocytopoiesis and may be involved in the development of reactive thrombocytosis and bone marrow mega‐karyocytic hyperplasia in various inflammatory diseases.
Ikujiro Nonaka's A Dynamic Theory of Organisational Knowledge Creation

Ikujiro Nonaka’s A Dynamic Theory of Organisational Knowledge Creation outlines the creation of organisational knowledge through the constant conversion of the two types of knowledge, tacit and explicit, which Nonaka believes has the potential to guide managers’ knowledge creation strategies. This argument is centred on the conviction that companies are not passive parties that simply utilise existing knowledge for providing solutions to the customers, and that organisations and environments simultaneously influence knowledge creation. This text is considered fundamental for the knowledge management field and as such, it has been utilised by a large number of academics.
Prevalence of Rift Valley Fever in Lusaka and Mazabuka, Zambia.

Summary Five out of 53 workers in a cattle abattoir in Lusaka had antibodies against Rift Valley fever (RVF). None of 40 workers in a pig abattoir were seropositive. Transmission of the virus by direct contact with infected cattle is suggested. In Mazabuka district, 19 out of 167 residents were positive for RVF; 13 out of the 19 had no previous contact with cattle. Hence, the possibility that transmission could occur by mosquito bite can not be excluded in rural areas. Zusammenfassung Auftreten von Rift Valley Fever in Lusaka und Mazabuka, Zambia Funf von 53 Arbeitern aus einem Rinderschlachthof in Lusaka hatten Antikorper gegen Rift Valley Fever (RVF)-Virus. Keiner von 40 Arbeitern eines Schweineschlachthofes war seropositiv. Dies last darauf schliesen, das eine ubertragung des RVF-Virus durch unmittelbaren Kontakt mit infizierten Rindern moglich ist. Im Mazabuka-Gebiet waren 19 von 167 Einwohnern seropositiv auf RVF-Virus: 13 von diesen Personen hatten keinen fruheren Kontakt zu Rindern. Es ist deshalb moglich, das die Krankheit in landlichen Gebieten auch durch Moskitostiche ubertragen wird.
Development of a sustainable Lean Six Sigma framework in healthcare sector

The healthcare sector is promoting the use of process improvement approaches resulting in several successful improvement projects. However, evidence, based on literature, points out that in a significant number of cases, healthcare organisations have failed to sustain the deployment of process improvement tools for long-term continuous improvements. Lean Six Sigma, which incorporates the speed and impact of Lean, with the quality and variation control of Six Sigma, is considered to have a high impact. Nevertheless, to reap the full benefits of LSS, it is necessary to develop a systematic approach to sustain LSS in healthcare organisations. Organisations have been shown to approach change from only three ways: functional, operational and ad hoc, neglecting a holistic or systemic analysis. Hence, the literature has not provided a systemic approach to change and improvement, which also includes the assessment of readiness for change. Therefore the objectives are to carry out an extensive literature review and survey to identify the reasons for organisations failing to sustain Lean Six Sigma. A list of factors critical for successfully sustaining Lean Six Sigma are identified and analysed using the ISM methodology. With the view to support healthcare professionals in integrating Lean Six Sigma in their organisation, this research develops a new framework (SLSS) to shift focus away from short term and towards long-term improvement. Furthermore, using a semi structured interview approach experts validate the framework. The framework will allow professionals to pay more attention on strategically important factors when integrating Lean Six Sigma in their organisation. The major outcome of this research is that the relationship between CSFs is analysed providing a distinctive view on how to handle them. Common approaches have focused on other aspects of research and were content with having identified CSFs, which led to the misconception that all CSFs are equally important. Hence, this research provides a more sophisticated view on this topic. In addition, the SLSS framework was build to fill the gap between implementation-focused and organisational culture focused frameworks. It can be used in conjunction with the organisation's preferred implementation framework in order to guarantee that the strategic component is covered.
