Background: The shoulder joint comprises of a large humerus head and smaller glenoid fossa. It is an incongruousball and socket type of joint. The joint has sacrificed its articular congruency for more range of motion. Thedominant upper limb is involved in activities of daily living (ADLs) such as self-grooming, eating, lifting objectsetc. Range of motion of the shoulder may be influenced by various factors and also dominance.Objective: The study aims to identify variation in flexibility of the shoulder joint in dominant and non-dominantupper limbs and to identify the various factors influencing it.Method: This cross-sectional study included young healthy adults of either gender between the age group of 18-26 yrs. Participants with history of shoulder injuries, dislocations, generalised hypermobility were excluded fromparticipation. The total sample size was 169 with 37 males and 132 females. The participants performed Apley’sscratch test for flexibility measurement bilaterally for both dominant and non-dominant shoulder.Result: The total number of sample size was 169 out of which 37 were males and 132 were females. Data from169 participants (165 right-hand dominant and 4 left-hand dominant) was analysed, and it was discovered thatthe dominant shoulder showed more flexibility than the non-dominant side. There was no gender difference inshoulder flexibility. It showed that the age was inversely proportional to flexibility of the shoulder joint. BMIshows to have a negative influence on the joint flexibility.Discussion: This study showed the dominant side shoulder to have more positive values according to the Apley’sscratch test compared to the non-dominant side. The flexibility values showed negative correlation with BMI.Conclusion: Flexibility in the dominant shoulder joint is more compared to the non-dominant joint. BMI influencesthe flexibility of the joint. The shoulder flexibility decreases with age. Gender doesn’t seem to have significantvariation in the shoulder joint flexibility.

Background: Colistin is an effective treatment option, recommended for carbapenem resistant gram-negative bacilli (CR-GNB) in critically ill patients. Due to high nephrotoxicity, dose management of Colistin is a tough decision to make. At standard dosage the efficacy of Colistin is not well defined. Consequently, strategies involving higher dosages were suggested. Objective: To evaluate the high dose of Colistin as non-inferior to standard dose in the treatment of CR-GNB in critically ill patients. Study Design: Retrospective comparative study Place and Duration of Study: Intensive Care Unit, King Saud Medical City Riyadh, Saudi Arabia from 1st January 2015 to 31st December 2017. Methodology: One hundred and ninety two patients that met the inclusion criteria from all participants were further divided into two groups. Group H (High dose) given the high dose of Colistin (9 million units intravenously (IV) loading dose, and then 9 million units/day in 2 or three divided doses) whereas group S was administered with standard dose (no loading dose, 6 million units/day). The primary endpoint of the study was the assessment of nephrotoxicity after the start of Colistin and secondary endpoints were the mortality within 14 days of commencing Colistin along with clinical effects and microbial clearance upon completion of treatment. Results: The results of the study established the non-inferiority of high dose of Colistin for the renal safety and also showed significant improvement in microbial clearance and length of ICU stay as compared to the standard dose. The other secondary end points such as mortality (p = 0.99), length of hospital stay (p = 0.39), and global improvement (p value of 0.06) revealed no significant difference between the two groups. Conclusion: The high dose of Colistin for the treatment of carbapenem resistance gram negative bacilli (CRGNB) was as safe as the standard dose for renal safety. But we also found that it also accelerates microbial clearance and reduces the time spent in the intensive care unit.

Many U.S. households have significant wealth late in life, contrary to the predictions of a simple life-cycle model. In this paper, we document stark differences between U.S. and Sweden regarding out-of-pocket medical and long-term-care expenses late in life, and use them to investigate their role in discouraging the elderly from dissaving. Using a consumption-saving model in retirement with significant uninsurable expense risk, we find that medical expense risk accounts for a quarter of the U.S.-Sweden difference in retirees' dissaving patterns. Furthermore, medical expense risk affects primarily financial assets, while its impact on housing is limited.

The distribution of fracturing and the type of fluid saturation in the geological environment, along with its structure, is the most important information for optimal development of oil and gas fields, including their search, exploration and development. Integrated use of seismic information about fluid saturation, fracturing and the structure of sedimentary strata helps to choose the optimal locations for the discovery of wells in order to obtain the maximum possible inflow of hydrocarbons into them. This approach drastically reduces the drilling of dry wells while performing prospecting and exploration works, significantly reduces the capital costs for their implementation and accelerates the commissioning of fields. In the development of the field, continuous seismic monitoring of fracturing and fluid saturation of the productive strata in real time allows the operative optimization of oil displacement schemes and operating modes of wells, choosing the optimal location and time for performing geological and technological measures, and controlling the geological and technical efficiency of their implementation, etc., the rate of recovery and the completeness of the oil extraction from the deposit while reducing capital and operating costs. To study the 2D-4D distribution of fracturing and fluid saturation in the geological environment by scientists and specialists of the «Scientific School of Oil and Gas Seismoacoustics by prof. Kuznetsov O.L.», innovative seismic technologies are created: «Seismic side-view locator»,» Seismolocation of foci of emission» and «Acoustic low-frequency survey», in which for obtaining this information, waves of diffuse reflection and microseismic emissions are used, not mirror reflection, as in traditional seismic surveys. As a result of experimental laboratory, well and field studies, the regularity of the amplitude-time parameters of seismoacoustic emission was determined depending on the type of fluid saturation of rocks and physical impacts, which was also used in the technologies of «Logging of seismoacoustic emission» to isolate oil-containing intervals in a section of wells and «Wave treatment of the reservoir» to increase the oil inflow into the well, including hard-to-recover highly viscous oil. Examples of the application of seismo-acoustic technologies for solving a wide range of applied problems in the development of oil and gas fields are given.

Mesh adaptation has proven to be very efficient for simulating transient multiphase computational fluid dynamics applications. In this work, we present a new parallel anisotropic mesh adaptation technique relying on an edge based error estimator. It provides a high level of accuracy while substantially reducing the computational effort. This technique enables a good capture of physical phenomena, boundary layers, interfaces, free surfaces and even multiphase turbulent flows, and has a great potential to simulate a large variety of applications. Current investigations explore the performance of the new algorithm on massively parallel resources. In this paper, we show that the developed adaptive meshing works very well in a parallel environment involving topological mesh modifications and dynamic repartitioning of parallel slots. It is also shown that the proposed methodology provides an additional gain in terms of computational cost due the production of a non-uniform mesh size distribution. Runs performed on national and European supercomputers will show the scalability and pertinence of our developments.

This thesis presents the study of the model order reduction for power grids and transmission networks. The specific focus has been the transient dynamics. A mathematical viewpoint has been adopted for model reduction. Power networks are huge and complex network, simulation for power grid analysis and design require large non-linear models to be solved. In the context of developing "Smart Grids" with the distributed generation of power, real time analysis of complex systems such as these needs fast, reliable and accurate models. In the current study we propose model order reduction methods both a-priori and a-posteriori suitable for dynamic models of power grids. The model that describes the transient dynamics of the power grids is complex non-linear swing dynamics model. The non-linearity of the swing dynamics model necessitates special attention to achieve maximum benefit from the model order reduction techniques. In the current research, POD and LATIN methods were applied initially with varying degrees of success. The method of TPWL has been proved as the best-suited model reduction method for swing dynamics model; this method combines POD with multiple linear approximations. For the transmission lines, a distributed parameters model in frequency-domain is used. PGD based reduced-order models are proposed for the DP model of transmission lines. A fully parametric problem with electrical parameters of transmission lines included as coordinates of the separated representation. The method was extended to present the solution of frequency-dependent parameters model for transmission lines. Cette these présente l'étude de la réduction de modeles pour les réseaux électriques et les réseaux de transmission. Un point de vue mathématique a été adopté pour la réduction de modeles. Les réseaux électriques sont des réseaux immenses et complexes, dont l'analyse et la conception nécessite la simulation et la résolution de grands modeles non-linéaires. Dans le cadre du développement de réseaux électriques intelligents (smart grids) avec une génération distribuée de puissance, l'analyse en temps réel de systemes complexes tels que ceux-ci nécessite des modeles rapides, fiables et précis. Dans la présente étude, nous proposons des méthodes de réduction de de modeles a la fois a priori et a posteriori, adaptées aux modeles dynamiques des réseaux électriques. Un accent particulier a été mis sur la dynamique transitoire des réseaux électriques, décrite par un modele oscillant non­linéaire et complexe. La non-linéarité de ce modele nécessite une attention particuliere pour bénéficier du maximum d'avantages des techniques de réduction de modeles. lnitialement, des méthodes comme POD et LATIN ont été adoptées avec des degrés de succes divers. La méthode de TPWL, qui combine la POD avec des approximations linéaires multiples, a été prouvée comme étant la méthode de réduction de modeles la mieux adaptée pour le modele dynamique oscillant. Pour les lignes de transmission, un modele de parametres distribués en domaine fréquentiel est utilisé. Des modeles réduits de type PGD sont proposés pour le modele DP des lignes de transmission. Un probleme multidimensionnel entierement paramétrique a été formulé, avec les parametres électriques des lignes de transmission inclus comme coordonnées additionnelles de la représentation séparée. La méthode a été étendue pour étudier la solution du modele des lignes de transmission pour laquelle les parametres dépendent de la fréquence. Esta tesis presenta un estudio de la reducción de modelos (MOR) para redes de transmisión y distribución de electricidad. El enfoque principal utilizado ha sido la dinámica transitoria y para la reducción de modelos se ha adoptado un punto de vista matemático. Las redes eléctricas son complejas y tienen un tamaño importante. Por lo tanto, el análisis y diseño de este tipo de redes mediante la simulación numérica, requiere la resolución de modelos no-lineales complejos. En el contexto del desarrollo de redes inteligentes, el objetivo es un análisis en tiempo real de sistemas complejos, por lo que son necesarios modelos rápidos, fiables y precisos. En el presente estudio se proponen diferentes métodos de reducción de modelos, tanto a priori como a posteriori, adecuados para modelos dinámicos de redes eléctricas. La dinámica transitoria de redes eléctricas, se describe mediante modelos dinámicos oscilatorios no-lineales. Esta no-linearidad del modelo necesita ser bien tratada para obtener el máximo beneficio de las técnicas de reducción de modelos. Métodos como la POD y la LATIN han sido inicialmente utilizados en esta problemática con diferentes grados de éxito. El método de TPWL, que combina la POD con múltiples aproximaciones lineales, ha resultado ser el mas adecuado para sistemas dinámicos oscilatorios. En el caso de las redes de transmisión eléctrica, se utiliza un modelo de parámetros distribuidos en el dominio de la frecuencia. Se propone reducir este modelo basándose en la PGD, donde los parámetros eléctricos de la red de transmisión son incluidos como coordenadas de la representación separada del modelo paramétrico. Este método es ampliado para representar la solución de modelos con parámetros dependientes de la frecuencia para las redes de transmisión eléctrica

Alsacia și Transilvania reprezintă două provincii istorice de frontieră, intens disputate de‑a lungul istoriei, care au fost mereu puse în legătură, atît în discursul politicienilor, cît și în cel al intelectualilor sau al istoricilor. Prin articolul nostru dorim să facem o pledoarie pentru o istorie comparată între Alsacia și Transilvania (ca două provincii de frontieră) și să aducem un prim set de argumente pentru această întreprindere științifică. Pornind de la avantajele și metodele de investigație ale istorie comparate, vom putea înțelege mai bine specificul identitar și modul în care aceste două provincii de margine s-au raportat la centrele lor de putere. În acest fel, istoria națională monolitică și exclusivă va fi înlocuită de o perspectivă fragmentară și/sau periferică, prin care vor ieși la lumină diferitele aspecte referitoare la: istoria locală sau regională, la regionalism sau la relația centru–periferie.
