The kinematics of molecular clumps surrounding hot cores in G29.96 0.02 and G31.41+0.31

We present high angular resolution interferometric observations of the 3 and 1.3 mm continuum emission, and HCO + (1{0) and SiO(2{1) v = 0 lines, obtained with the Owens Valley Radio Observatory millimeter-wave array, toward two hot cores (HCs) associated with two well known ultracompact (UC) H ii regions: G29.96 0.02 and G31.41+0.31. These HCs are believed to host young forming massive stars which have been suggested to be surrounded by massive rotating accretion disks. The aim of these new observations is to study the structure and kinematics of the molecular clumps surrounding the HCs and nearby UC H ii regions at moderately high angular resolution. Our observations reveal that the clumps within which the HCs and UC H ii regions are embedded have a complex kinematical structure. The total mass of the clumps is estimated to be in the range 1000{3000 M, consistent with previous ndings. Our observations also show compelling evidence that the clump in G29.96 0.02 is contracting onto the HC position, suggesting that the accretion process onto the massive young stellar object embedded in the HC is still ongoing. In these objects the kinematical structure that we observe is also compatible with the presence of a massive rotating disk within the HC, even though we cannot prove this suggestion with our data. The case of G31.41+0.31 is more complicated, and our data, although consistent with the presence of an inner disk and an infalling envelope around it, do not have the required spatial resolution to resolve the dierent structures.
Редукционная аннулопластика фиброзного кольца аутоперикардом при хирургическом лечении недостаточности митрального клапана

BACKGROUND: Despite the widespread usage of all-type rings in the surgical treatment of patients with mitral valve insufficiency (MV) and dilatation of its fibrous annulus, the researches on this topic are in progress. AIM: To study the short- and long-term results of narrowing annuloplasty of the MV utilizing an autopericardium strip of calculated length. MATERIALS AND METHODS: The study group consisted of 21 patients (average age 60.9 ± 4.3 years, women 23.8 %) with MV insufficiency of non-rheumatic ethiology. The narrowing of the fibrous annulus during valve reconstruction has been performed along with the posterior 2/3 of their circle using interrupted horizontal sutures. With those sutures, an autopericardial strip of the calculated length has been secured to the annulus. The length of the strip has been calculated according to the original method, according to the data obtained during preoperative transesophageal echocardiography. The length of the strip was 2/3π ∙ D (mm), where D — the existing length of the anterior leaflet of the MV in the middle portion from the fibrous annulus to the free edge in the zone of the A2 segment. The control group consisted of 38 patients with non-rheumatic MV insufficiency (average age 59.1 ± 3.5 years, women 23.7 %); the strengthening and narrowing of the fibrous annulus have been performed using a strip made from a wicker vascular prosthesis. The length was 55 mm, equal for all the patients. In both groups, in addition to the narrowing of the fibrous annulus, other types of mitral valve-sparing surgery (partial resection of MV leaflets, suture leaflets techniques, their combination) and combined procedures (coronary bypass surgery, left ventricle reconstructions for postinfarction aneurysms) have been also performed. RESULTS: In the studied groups, the safety and reliability of the performed restrictive MV annuloplasty procedures have been demonstrated. During the follow-up period up to 8 years (average 3.5 ± 0.7 years), there was no recurrence of significant mitral regurgitation, which would require repeated surgery in both groups. Narrowing annuloplasty of the fibrous annulus of MV with a strip from the autopericardium of an individual calculated length allows to perform a more accurate anatomical correction of the valve compared with the control group. The existing methods of mitral annuloplasty, their advantages and disadvantages are discussed. CONCLUSIONS: The proposed method of restrictive annuloplasty of the MV with an autopericardial strip of the calculated length allows to perform a reliable and safe correction of the dilated fibrous annulus in patients with mitral insufficiency during valve-preserving operations.

Research on Energy Management Strategy for GCPBS

Integrating solar power into the power grid is significant for the rapid acceleration of energy transition. As a result, it is urgent to make appropriate operational strategies for grid-connected photovoltaic battery systems (GCPBS). At present, a variety of energy management strategies have been proposed, while the influence of battery degradation and energy flow distribution hasn’t been considered, which also makes a huge difference to grid-connected photovoltaic-battery system operation. Therefore, a novel energy management strategy is proposed in this paper to provide optimal energy utilization. Moreover, a case study using data from California is utilized to investigate the performance of the proposed method, where a widely used operation strategy is utilized to be compared. Results prove that the proposed method can control flexibly energy flow to achieve the minimum cost of GCPBS operation with reasonable battery charging and discharging process, and the battery is charged at tough prices and discharged at high prices, where coupling effects of all hours and price are considered and the battery is fully utilized.
Transferring, Translating and Transforming: an Integrative Framework for Managing Knowledge across Boundaries Transferring, Translating and Transforming: an Integrative Framework for Managing Knowledge across Boundaries Transferring, Translating and Transforming: an Integrative Framework for Managin

Organizations must establish processes for managing knowledge across boundaries because of the specialized and task-dependent forms of knowledge required to deliver products and services. To address this challenge an integrative framework is developed that identifies and integrates the value of different approaches to managing knowledge in organizations that are often presented as incompatible in the literature. The framework describes three progressively complex types of boundaries: syntactic, semantic and pragmatic. Each increasingly complex boundary requires a more complex process to facilitate communication and innovation across specialized forms of knowledge. The framework categorizes types of boundaries, gauges their complexity, and then describes the processes involved in managing knowledge across each of them. The development of a new engineering tool in an automotive firm is presented to illustrate the conceptual strength of this framework.
Écoulement de fluides immiscibles dans un canal submillimétrique : stabilité et application à la rhéologie

Nous avons developpe une methode de mesure des proprietes rheologiques de fluides complexes sur un dispositif microfluidique. Notre principe de mesure repose sur l’ecoulement de deux fluides immiscibles que nous faisons couler parallelement l’un a l’autre. De part la tension de surface entre les deux fluides, cette forme d’ecoulement n’est pas exclusivement obtenue et il est egalement possible d’observer la formation de gouttes d’un fluide dans l’autre. Afin de predire les conditions d’obtention des ecoulements paralleles, requis pour notre application, nous avons etudie l’instabilite de Rayleigh Plateau d’un jet laminaire dans un environnement confine. Nous proposons de reduire l’etude du systeme a trois parametres : le rapport de viscosite, le confinement du jet et un nombre capillaire. Les resultats obtenus par une telle approche sont en bon accord avec les resultats experimentaux. Nous avons ensuite utilise ces ecoulements paralleles pour mesurer les courbes d’ecoulement de fluides complexes en utilisant une methode empruntee a la rheometrie capillaire. La determination des proprietes geometriques de l’ecoulement parallele entre le fluide a determiner et un fluide de reference permet de remonter a la chute de pression au sein de l’ecoulement dont le debit est connu. Les resultats obtenus dans diverses geometries nous ont permis de valider cette approche dans une plage de cisaillement comprise entre 0,1 s-1 et 5000 s-1 et une gamme de viscosite allant de 1 a 70000 mPa? s et ce, avec moins de 250 µL d’echantillon.
IMAGE PROCESSING, PATTERN RECOGNITION An efficient algorithm for overlapping bubbles segmentation

Image processing is an effective method for characterizing various two-phase gas/liquid flow systems. However, bubbly flows at a high void fraction impose significant challenges such as diverse bubble shapes and sizes, large overlapping bubble clusters occurrence, as well as out-of-focus bubbles. This study describes an efficient multi-level image processing algorithm for highly overlapping bubbles recognition. The proposed approach performs mainly in three steps: overlapping bubbles classification, contour segmentation and arcs grouping for bubble reconstruction. In the first step, we classify bubbles in the image into a solitary bubble and overlapping bubbles. The purpose of the second step is overlapping bubbles segmentation. This step is performed in two subsequent steps: at first, we classify bubble clusters into touching and communicating bubbles. Then, the boundaries of communicating bubbles are split into segments based on concave point extraction. The last step in our algorithm addresses segments grouping to merge all contour segments that belong to the same bubble and circle/ellipse fitting to reconstruct the missing part of each bubble. An application of the proposed technique to computer generated and high-speed real air bubble images is used to assess our algorithm. The developed method provides an accurate and computationally effective way for overlapping bubbles segmentation. The accuracy rate of well segmented bubbles we achieved is greater than 90 % in all cases. Moreover, a computation time equal to 12 seconds for a typical image (1 Mpx, 150 overlapping bubbles) is reached.
Double-conditional smoothing of high-frequency volatility surface in a spatial multiplicative component GARCH with random effects

This paper introduces a spatial framework for high-frequency returns and a faster double-conditional smoothing algorithm to carry out bivariate kernel estimation of the volatility surface. A spatial multiplicative component GARCH with random effects is proposed to deal with multiplicative random effects found from the data. It is shown that the probabilistic properties of the stochastic part and the asymptotic properties of the kernel volatility surface estimator are all strongly affected by the multiplicative random effects. Data example shows that the volatility surface before, during and after the 2008 financial crisis forms a volatility saddle.
UKRAINIAN ECONOMY DURING THE MILITARY AGGRESSION OF THE RUSSIAN FEDERATION AND IN THE PERIOD OF POST-WAR RECONSTRUCTION

It is shown that the post-war revival of Ukraine's economy is impossible on the basis of the existing economic model, which is based on the adaptation of domestic industries to the trends in world commodity markets. This model ensured economic "growth without development" and led to the deindustrialization. The need for the formation of an economic model, which will envisage the path to a new industrialization, is substantiated. New industrialization should begin with setting up the industries that could continue the technological chains of commodities production and easily replace imports. The analysis of the structure of domestic GDP use showed that domestic consumption did not become a driver of economic development. The existing economic model does not use exports to develop domestic production and increase the income of population. Therefore, when forming a new model of national economy, it is necessary to take into account the peculiarities of the movement of goods, capital, and labor depending on the waves of globalization and localization of world markets. Since today the world economy has entered a phase of global localization of production, the national development strategy of our country should also focus on creating conditions for the formation of national technological added value chains. To this end, it is necessary to increase a rate of capital accumulation, create new sub-sectors, new added value. The "Marshall Plan" for Ukraine became the main idea for restoring our economic development through the modernization and renewal of production potential. It is proposed that aid recipient countries submit thorough investment projects to a special agency that would establish requirements, criteria and estimates for their financial support. The "Marshall Plan" for Ukraine may become a basis of the national revival strategy, thus, Ukraine must be an active subject in the process of choosing its own development strategy, when its national interests will be realized with the help of this plan.
VHF ANTENNA INTEGRATED INTO A CLASSICAL FIBRE METAL LAMINATE FUSELAGE PANEL

Replacement of protruding antennas by integrated alternatives will reduce the energy consumption and NO x and CO 2 emissions of an aircraft. This paper proposes and integrated VHF cavity backed slot antenna that is suitable to replace blade antennas. To reduce the size of the cavity a parallel plate resonator is used. The slot is integrated into a fibre metal laminate fuselage panel. A bookleafing principle is used to reinforce the panel at the position of the slot, making sure the material quality is not reduced. Measurement results of a demonstrator antenna show the feasibility of the proposed antenna. Moreover, the paper discusses several electromagnetic and structural design trade-offs for this integrated antenna.
Measurements of the natural plasma flow during the precursor of TCABR density limit disruptions

Introduction Magnetic islands are known to degrade confinement of energy and particles in tokamak plasmas. They are also present in the precursor of density limit disruptions being observed until the onset of the energy quench of the disruption. The subject of the effect of plasma flow on tearing mode stability has been studied both theoretically [1] and experimentally [2]. However the experimental work has focused on plasmas with Neutral Beam Injection (NBI), which adds high momentum to both the plasma and the island, deviating them from their natural velocities. It is important to know the plasma/island rotation behavior without NBI, not just to know their natural values but because future large tokamaks, like ITER, are expected to have low plasma rotation due to both large plasma inertia and low applied torque. In this work we will show experimental values of the ion velocity and the magnetic island velocity measured in TCABR ohmic plasmas, without NBI, and during the precursor of a density limit disruption. In this way it was possible to compare the natural plasma velocity with the island velocity. The ion velocity was inferred from Doppler spectroscopy of the impurity lines of CVI. Details of this diagnostic system and an error analysis of the measured signal can be found in [3]. With the present set up, the toroidal velocity can be measured with time resolution equivalent to 600 Hz and precision somewhat better than 5 km/s.
Introducing E-Government in Developing Countries with an analysis of the Egyptian e-Government services

Online Identification and Authentication is an essential requirement for providing e-services. Few studies have investigated the challenges facing e-Government and IDM in developing countries and, to the best of our knowledge, none of the existing research has studied the challenges facing online identification and remote authentication in developing countries, such as the North Africa Countries (NAC), where a relatively large proportion of citizens are illiterate. Therefore, the design of a national IDM system in a NAC must explicitly consider illiteracy to allow this group of citizens to benefit from online services. Egypt is one of the NAC, which has implemented online identification and authentication services that are widely recognized as the most advanced among the NAC. This paper analyses the Egyptian digital IDM in order to identify IDM requirements for online identification and authentication services that guarantee equal access to online services and an inclusive society. The study identifies strengths and weaknesses of the Egyptian e-Government and IDM services, which we believe are common to most NAC, since the NAC are quite similar in terms of social culture, citizen’s education level and skills, citizen’s behaviours, digital infrastructure and legislation, but also common to many other developing countries. Our analysis of the Egyptian e-Government services indicates that the security requirements and principle of equal access are not fully met, which illustrates the difficulty of introducing e-Government in developing
Effects of Aprepitant on the Pharmacokinetics of Controlled-Release Oral Oxycodone in Cancer Patients

Purpose Oxycodone is a µ-opioid receptor agonist widely used in the treatment of cancer pain. The predominant metabolic pathway of oxycodone is CYP3A4-mediated N-demethylation to noroxycodone, while a minor proportion undergoes 3-O-demethylation to oxymorphone by CYP2D6. The aim of this study was to investigate the effects of the mild CYP3A4 inhibitor aprepitant on the pharmacokinetics of orally administered controlled-release (CR) oxycodone. Method This study design was an open-label, single-sequence with two phases in cancer patients with pain who continued to be administered orally with multiple doses of CR oxycodone every 8 or 12 hours. Plasma concentration of oxycodone and its metabolites were measured up to 8 hours after administration as follows: on day 1, CR oxycodone was administered alone; on day 2, CR oxycodone was administered with aprepitant (125 mg, at the same time of oxycodone dosing in the morning). The steady-state trough concentrations (Css) were measured from day 1 to day 3. Results Aprepitant increased the area under the plasma concentration-time curve (AUC0–8) of oxycodone by 25% (p<0.001) and of oxymorphone by 34% (p<0.001), as well as decreased the AUC0–8 of noroxycodone by 14% (p<0.001). Moreover, aprepitant increased Css of oxycodone by 57% (p = 0.001) and of oxymorphone by 36% (p<0.001) and decreased Css of noroxycodone by 24% (p = 0.02) at day 3 compared to day 1. Conclusions The clinical use of aprepitant in patients receiving multiple doses of CR oxycodone for cancer pain significantly altered plasma concentration levels, but would not appear to need modification of the CR oxycodone dose.

The pipes and the tubes and the ducts may be secured together when they are folded to the compact folding structure.
On nondiagonal quasi-quantum groups over finite abelian groups

In this paper, we initiate the study of nondiagonal ﬁnite quasi-quantum groups over ﬁnite abelian groups. We mainly study the Nichols algebras in the twisted Yetter-Drinfeld module category k G k G YD Φ with Φ a nonabelian 3-cocycle on a ﬁnite abelian group G. A complete clariﬁcation is obtained for the Nichols algebra B ( V ) in case V is a simple twisted Yetter-Drinfeld module of nondiagonal type. This is also applied to provide a complete classiﬁcation of ﬁnite-dimensional coradically graded pointed coquasi-Hopf algebras over abelian groups of odd order and conﬁrm partially the generation conjecture of pointed ﬁnite tensor categories due to Etingof, Gelaki, Nikshych and Ostrik.
Social Class and Undergraduate Degree Subject in the UK ∗

Despite the potential interest of the topic for its implications in terms of intergenerational mobility, the choice of university undergraduate degree subject has been rarely investigated in the UK. In this paper, we use individual-level data from the Universities’ Statistical Record 1980-1991 in order to analyse the effect of students’ social class on the probability of enrolling in different undergraduate study fields in the UK. We consider three broad subject areas: quantitative subjects (QS), non-quantitative subjects (NQS) and law and medicine (L&M). By estimating a trinomial probit model, we find that individuals from social class I differ in the probability of enrolling QS and L&M with respect to students with lower social class backgrounds. Namely, the former are relatively more likely to enroll in L&M and less likely to enroll in QS. However, our estimates show that the main differences across individuals in the subject enrolled stem from the type of secondary school curriculum. JEL classification: I21 J24
Use of Gamification to Approach the Algebraic Language and Equations in 1st Grade of Secondary Education

Active methodologies, as innovative agents, are becoming more and more frequent in education, but they are not a majority. However, it is a good resource to adapt the educational system to the current society based on knowledge and information. This article shows a useful and effective tool to connect with the needs and interests of students through an active methodology. The proposal, a gamification (teaching-learning methodology based on the mechanics of games), approaches the students of 1st grade of secondary education to the algebraic language and equations, combining cooperative learning activities. Working through gamification means a higher academic performance, an increase in motivation and the development of a positive attitude allowing, in addition, to attend to diversity in the classroom and the use of ICT promoting collaborative work. Gamification, based on the use of ICT, facilitates the acquisition of knowledge in a more attractive way, favoring their performance.
Plant and Animal Responses to Grazing Systems in the Nebraska Sandhills

warm and cool season herbage) did not differ consistently between the two grazing systems. The decline in diet quality (CP and IVOMD) through the 5-month grazing season did not differ consistently between the two systems, and ADG of spayed heifers was similar. The lack of increased forage production and animal performance responses to SDG indicate that the higher input costs associated with SDG are not justified in the Nebraska Sandhills.
