Remodelación de cavidades izquierdas en el posoperatorio de retorno venoso pulmonar anómalo total: utilidad del NTProBNP

El retorno venoso pulmonar anómalo total se caracteriza por la falla de conexión entre la aurícula primitiva y el retorno venoso pulmonar, este último se conecta al retorno venoso sistémico a través de la persistencia de conexiones embrionarias. En esta patología, el ventrículo izquierdo suele tener un tamaño en el límite inferior de la normalidad, con una aurícula izquierda pequeña y atrófica. En el período posoperatorio las cavidades izquierdas deben manejar todo el retorno venoso pulmonar, lo que podría determinar sobrecarga de estas cavidades. Presentamos dos casos de posoperatorio de retorno venoso pulmonar anómalo total, evaluando la relación entre el tamaño auricular izquierdo y los niveles de péptido natriurético. Se plantea como hipótesis una disfunción en el llenado de cavidades izquierdas como sustrato causal de este fenómeno, teniendo como consecuencia modificaciones adaptativas anatómicas y funcionales. La determinación de los niveles de péptido natriurético podría ser útil en la monitorización de este proceso adaptativo.
The Dynamics of Ski Skating 375 The Dynamics of Ski Skating

We discuss the dynamics of ski skating, in particular, the optimization problem: Maximize average speed for a given power. We begin with a mathematical model of ski skating. To simplify the analysis, we limit our attention to ski skating with no poles on a level plane. We also limit our attention to the physics of ski skating; we ignore most biomechanical considerations. In the early days of skating, ski instructors often said: “Take a long glide on a flat ski. ” Many skiers interpreted this to mean: “Take a passive glide, then give a short hard push to the side. ” As an application of our theory, we show that this advice is wrong. We show that the skier should start pushing to the side as soon as possible.
Autonomous Vehicle Reverse Parking System

:- Parking is considered to be one of the hardest thing for the driver’s while driving the car which leads to high stress maneuver. This paper proposes the concept of autonomous reverse parking system where vehicle is going to park in its respective slot. The first step is to identify whether the slot is vacant or occupied. For this the Image processing techniques are used to identify it. Here the vacancy is determined in both ways, first with the help of slot markings and other with the presence of vehicle in the slot. After the detection of the vacant slot, with the help of MATLAB programming path for the vehicle to follow is being generated. This mainly deals with the steering angle of the wheel and the dimensions of the vehicle. So that vehicle park’s safely in its slot. In order to ensure that the vehicle is following in the path generated by the MATLAB commands Kalman filter tracking techniques are used. By this we can able to park the vehicle autonomously in the parking slot. Also the hardware was developed to interface with raspberry pi to implement in four wheeled robot.
A NMOS Linear Voltage Regulator for Automotive Applications

The electronization of automobiles is considered to be a revolution in automotive technology development progress. One trend for automotive electronics design is pursuing higher level integration. System level integrated circuits are needed to simplify the automotive electronics design and increase the reliability of automobiles. In this thesis, a prototype of linear voltage regulator is designed for system level integration. Instead of conventional PMOS linear regulator topology, a NMOS power transistor is chosen as the pass device on considerations of smaller silicon area and better dynamic performance. The characteristic differences of PMOS and NMOS linear regulators are analyzed. Based on the frequency behavior analysis of these two types of regulators, a frequency compensation scheme for the NMOS linear regulator is purposed in this thesis. This purposed scheme is able to accommodate the wide frequency variation of the NMOS linear regulator output pole. The effectiveness of frequency compensation is examined by both mathematical modeling and transistor level simulation. The over-current protection of the NMOS linear regulator is also designed, which is realized by applying another current regulation loop to the voltage regulator. This NMOS linear regulator is able to maintain a constant output current around 250mA in over-current protection scenario. Compared to the existing PMOS linear regulator counterpart, the off-chip ceramic capacitor of this NMOS linear regulator can be reduced to 220nF (10x smaller) without sacrificing the ±2% output voltage accuracy within -40 C∼175 C. The regulator quiescent current at no current load scenario is 12μA. Owing to the introduction of adaptive biasing scheme, the maximum quiescent current is 1.31mA. This adaptive biasing only degrades the current efficiency by maximum 4%. At the end of the thesis, possible maximum load current and external capacitor scaling abilities of this NMOS linear regulator are discussed.
Trade Liberalization and Growth : Plant-Level Evidence from Switzerland 1

This paper estimates the effect of trade liberalization on growth, using plant-level data from Switzerland. We employ a natural experiment framework to quantify the effect of a bundle of treaties liberalizing trade between Switzerland and the EU enacted in June 2002 ("Bilateral Agreements I") on the growth of Swiss plants. Using both a semi-parametric difference-indifferences and a matching approach, we find that the liberalization of trade increased the growth of affected plants by 1-2 percent during the first six years after liberalization. Our results suggest that trade liberalization has a relevant effect on growth.
ANALISIS GEOSPASIAL UNTUK POTENSI BANJIR CILEUNCANG DI KOTA BANDUNG (STUDI KASUS: BANJIR PASTEUR DAN BANJIR PAGARSIH)

Banjir cileuncang adalah suatu terminologi yang diangkat dari peristilahan lokal untuk suatu fenomena yang saat ini menjadi potensi bencana di wilayah perkotaan. Dalam kasus di Kota Bandung, banjir cileuncang yang terjadi pada tanggal 24 Oktober dan 9 November 2016 telah melumpuhkan jalan-jalan di sekitar Pasteur dan Pagarsih yang menimbulkan kerugian yang tidak sedikit. Analisis geospasial merupakan analisis keruangan yang dilakukan untuk mengetahui penyebab banjir yang terjadi. Hasil menunjukkan semua kejadian banjir cileuncang yang melumpuhkan jalan utama Kota Bandung pada tanggal 24 Oktober dan 9 November 2016 berada di sub DAS Cibeureum. Sub DAS ini dipisahkan menjadi dua daerah tangkapan air karena keberadaan Sesar Lembang. Hutan lindung masih ditemukan di hulu sub DAS Cibeureum yang berada di sebelah utara Sesar Lembang. Daerah Selatan Sesar Lembang, tidak ditemukan lagi daerah resapan berupa hutan di Sub DAS ini. Tutupan lahan didominasi oleh pemukiman (71,15%), sehingga hampir semua air hujan menjadi air limpasan. Morfologi yang miring (42 o ) dari patahan Lembang ke Pasteur membuat aliran limpasan air menjadi deras. Oleh karenanya perlu dilakukan peningkatan manajemen di Sub DAS Cibeureum.

HyperLEDA. III. The catalogue of extragalactic distances

We present the compilation catalogue of redshift-independent distances included in the HyperLEDA database. It is actively maintained to be up-to-date, and the current version counts 6640 distance measurements for 2335 galaxies compiled from 430 published articles. Each individual series is recalibrated onto a common distance scale based on a carefully selected set of high-quality measurements. This information together with data on HI line-width, central velocity dispersion, magnitudes, diameters, and redshift is used to derive a homogeneous distance estimate and physical properties of galaxies, such as their absolute magnitudes and intrinsic size.
Review on Diagnostic Techniques of Bovine Tuberculosis

Bovine tuberculosis is a major infectious disease of cattle, other domesticated animals and certain wildlife populations. It is one of the zoonotic diseases and can be diagnosed with different techniques. The currently used techniques are acid fast staining which is a cost-effective tool for diagnosing tuberculosis case and to monitor the progress of treatment and it has also drawbacks such as the low sensitivity in the immune-suppressed individuals; After death, infection is diagnosed by necropsy, histopathological and bacteriological examination and biochemical tests like nitrate reduction, niacin production, deamination of pyrazinamide and urease tests. Immunological diagnostic techniques like tuberculin skin tests: Single intradermal test, comparative intradermal test, short thermal test and stormont test; Blood based diagnostic techniques like gamma interferon assays, Enzyme-linked immune-sorbent assays and lymphocyte proliferation assay, culture of mycobacterium and molecular diagnostic techniques which involves polymerase chain reaction, is a method that allows direct identification of the M. tuberculosis complex. Spoligotyping, restriction fragment length polymorphism, variable number tandem repeats typing are the techniques used for concurrent detection and typing of mycobacterium species at strain level. Its clinical usefulness over the other techniques is determined by its rapidity, both in identifying causative bacteria and in providing molecular epidemiologic information on strains. However, it holds drawbacks of being expensive and requiring well-equipped laboratory and skilled laboratory personnel, which are not always available in endemic areas. Thus, both conventional and molecular tools should be effectively used to diagnosis Tuberculosis.
Nanoparticles and endothelium: An update on the toxicological interactions

Adverse effects of environmental nanoparticles are emerged due to their escape from the macrophage surveillance and access to microcirculation. Endothelium acts as a physiological barrier lining up the vessel walls and controls the transfer of nanoparticles between the blood and interstitial space. Similarly, the blood–brain barrier at the level of brain microcirculation is the major site of blood-nervous system exchange and constitutes the physical barrier. However, the loss of endothelial function and integrity may result in the uncontrolled passage of the nanoparticles. Despite of some adverse properties, nanosized materials continue to be used inevitably in daily life. However, their mechanism of action in the exposed organism and their potential toxic effects are still being investigated in order to take preventive measures to save the human health. Thus, this review focuses on the possible output of the interaction of endothelium with the nanomaterials and the significance of the barriers during the exposure to nanoparticles.
EXPLANATION OF INTRINSIC AND EXTRINSIC JOB SATISFACTION VIA MIRROR MODEL

One of the most important issues focused by managers is to ensure effectiveness and efficiency of human resources in organizations. How can effectiveness and efficiency be achieved in an organization? Answer of this question relies heavily on job satisfaction of personnel. Job satisfaction refers to the general attitude developed by the individual towards her/his job. For this reason, job satisfaction cannot be seen but felt. This feeling depends also on working environment and environmental conditions. As an abstract concept, job satisfaction consists of many components. However, more simply, factors ensuring job satisfaction are basically divided into two groups; namely, intrinsic and extrinsic job satisfaction factors. Intrinsic factors refer to the attitude of the individual towards her/his job while the extrinsic factors refer to the factors related to the working environment. When combined, these two factor groups ensure individual to get job satisfaction. These two fundamental factor groups reflect both physiological and psychological state of the individual. Job satisfaction is associated with not only financial gains but also the socio-psychological gains brought by the job. In addition, colleagues and superiors of the personnel play an important role in personnel satisfaction. Achievement of job satisfaction will be reflected to the organization as positive outputs. In the light of the literature review, effects/reflections of intrinsic and extrinsic job satisfaction on/to the organization are explained via mirror model. As is known, mirror reflects any image directly back to it. As shown in the model, intrinsic and extrinsic motivation factors have positive effects on the organization. In other words, these factors have positive reflections on the organization. These positive outputs and reflections generally emerge as a sense of organizational citizenship, high motivation and increase in organizational learning and job satisfaction.
Population Models With Delay in Dynamic Environment

We study the combined effects of periodically varying carrying capacity and survival rates on the fish population in the ocean (sea). We introduce the Getz type delay differential equation model with a control parameter which describes how fish are harvested. We will modify and extend harvesting model of an exploited fish population to include periodic and rotational harvesting rates. We study the existence of global solutions for the initial value problem, extinction and persistence conditions, and the existence of periodic solutions.
The relationship between small-scale and large-scale ionospheric electron density irregularities generated by powerful HF electromagnetic waves at high latitudes

Satellite radio beacons were used in June 2001 to probe the ionosphere modified by a radio beam produced by the EISCAT high-power, high-frequency (HF) transmitter located near Tromso (Norway). Amplitude scintillations and variations of the phase of 150- and 400-MHz signals from Russian navigational satellites passing over the modified region were observed at three receiver sites. In several papers it has been stressed that in the polar ionosphere the thermal self-focusing on striations during ionospheric modification is the main mechanism resulting in the formation of large-scale (hundreds of meters to kilometers) nonlinear structures aligned along the geomagnetic field (magnetic zenith effect). It has also been claimed that the maximum effects caused by small-scale (tens of meters) irregularities detected in satellite signals are also observed in the direction parallel to the magnetic field. Contrary to those studies, the present paper shows that the maximum in amplitude scintillations does not correspond strictly to the magnetic zenith direction because high latitude drifts typically cause a considerable anisotropy of small-scale irregularities in a plane perpendicular to the geomagnetic field resulting in a deviation of the amplitude-scintillation peak relative to the minimum angle between the line-of-sight to the satellite and direction of the geomagnetic field lines. The variance of the logarithmic relative amplitude fluctuations is considered here, which is a useful quantity in such studies. The experimental values of the variance are compared with model calculations and good agreement has been found. It is also shown from the experimental data that in most of the satellite passes a variance maximum occurs at a minimum in the phase fluctuations indicating that the artificial excitation of large-scale irregularities is minimum when the excitation of small-scale irregularities is maximum.
Soft Computing for Terahertz Metamaterial Absorber Design for Biomedical Application

The terahertz region of the electromagnetic spectrum plays a vital role in biomedical imaging due to its sensitivity to vibrational modes of biomolecules. Biomedical imaging may be used to distinguish between the infected (cancer) and the non-infected tissues (A.J.F. Fitzgerald, V.P. Wallace, M. Jimenez-Linan, L. Bobrow, R. J. Pye, A.D. Purushotham, and D. D. Arnone, Radiology, May 2006), which requires broad band and highly efficient radar absorbing material (RAM) designs to obtain high resolution image of the tissues. In this paper, a novel RAM design with high efficiency over the required wideband is presented. The performance is enhanced considerably by introducing an optimized metamaterial split ring resonator (SRR). Such an application requires design of metamaterial structures for a desired frequency range (equivalent to the operational frequency of the RAM design). A particle swarm optimization (PSO) algorithm is developed here, which optimizes the resonant frequency and provides the structural parameters. This optimized design is further used as one of the layers of RAM design. The resulting optimized structure provides a near unity absorption within the required wideband frequency range. The RAM design presented here consists of 4 layers. The layers are composed of a metallic (gold) layer adjacent to a dielectric spacer layer. The thickness of the gold layer is 0.4 μm, and that of the dielectric spacer is 8 μm. The gold layer is sandwiched between the dielectric spacer made up of polymide. The conductivity of the gold layer is 4.09×107 s/m. The permittivity of the polyimide layer is 2.8814, and permeability is unity. The top layer made of gold is an array of SRR structure (metamaterial). The SRR structure designed here contains inductances and capacitances. The linear bars act as inductive elements whereas the gaps act as capacitive elements, which contribute to the permittivity and permeability of the structure. The optimized square SRR is introduced as the top layer of the RAM design. The scattering parameters of the designed structure are extracted and used for calculation of absorption. It is observed that the absorption is above 99.32 % at 1.16 THz, which is sufficient for biomedical spectroscopy applications.
Have Spanish companies built greater entrepreneurship after privatization

This study analyses some of the strategic and organizational changes experienced in public firms following privatization in its double facet: sale of companies and deregulation. Specifically, we analyse the process of innovation in terms of products, processes and organization. We also look into the development of new businesses and strategic renewal, which in the end shape the entrepreneurial capacity of a company. A sample of Spanish firms which were privatized between 1985 and 2000 shows that after privatization, these companies have experienced a significant increase in entrepreneurship. These changes are even more appreciable when a high sector competition is added to the ownership shift. Once they join the private sector, their level of product, process and organizational innovation is higher. They also develop new businesses at national level, reinforce their international activity and embark on strategic renewal processes by shedding the lesser profitable businesses and modifying their competitive strategy so as to gain efficiency.

A summary of the characteristics of those structures is presented in the paper.
Synthesis and characterisation of aluminium-silicon-silicon carbide composite

Aluminium-silicon-silicon carbide composite was prepared by mechanical mixing (300 rpm) of silicon carbide powder (−300 mesh) in solidifying solid-liquid slurry of hypoeutectic, eutectic and hypereutectic compositions of aluminium-silicon alloy. Requisite amount of hot (300°C) silicon carbide powder was charged into agitating metallic melt of aluminium-silicon matrix alloy and mixing continued while dropping the temperature of the system. The mixing period was 3-4 min during which temperature of the system dropped to 15±5°C below the liquidus. On completion of mixing, plumbago crucible containing the composite slurry was taken out from the furnace and finally solidified composite was removed from the crucible for the further study. X-ray diffraction analysis indicated the presence of silicon carbide in the composite. Silicon carbide occurred in the grain boundry regions associated with silicon and fragmented dendrites together with eutectic mixture. Strength, hardness and wear resistance of composite increased with increase of silicon carbide content. Coefficient of friction of composite having higher amount of silicon carbide was always lower than the composite with lower amount of silicon carbide, whether the tests were conducted in lubrication, semi-dry and dry sliding conditions. IPC Code: C22C47/00, C22C49/00
On the rating system in alpine skiing racing: Criticism and new proposals

Like most sports, alpine skiing has international regulations – its regulations specifically designed by the FIS, that is, the Fédération Internationale de Ski or International Ski Federation– aimed at coordinating competitions and rating athletes. FIS points, as they are called, represent the core of the rating system, as they facilitate the rating of athletes involved in competitions for each of the five alpine skiing disciplines, that is, slalom, giant slalom, super-G, downhill, and combined. The objective of this article is to analyse the current rating system, giving special attention to the FIS points’ construction and updating system and focusing on the potential weaknesses. Two major weaknesses emerge from this analysis: (1) the questionable update process of the FIS points, based on the average of the best two results obtained in a discipline of interest, and (2) the lack of a general rating of athletes based on their eclecticism, that is, the ability to obtain good results in as many different disciplines as possible. The second part of the article presents some proposals for sorting out the above weaknesses. The description therein is supported by several practical examples, based on real and hypothetical data.
