Cardiac Magnetic Resonance Images (MRI) are chastely indispensable implement for truthful demarcation of the left Ventricle myocardium for purposeful and serviceable cardiac examination. Dissection of MRI principally the leftward ventricle (LV) is a blistering focus with extraordinary perplexing owed to deceive delineation such as percentages misalignment in its position, in homogeneity of sequential portions and to clinch divergence in focus of adjoining pixels for the change in the body fluid drift. In this effort, we put forward a scheme to inevitably fragment the leftward Ventricle of MRI images by Round Hough Transform (RHT) initially by locating the seed point stalked a circle with apt radius as basal region and verdict the ROI in the image. Adjoining the center, apex region of the left ventricle is positioned till the extent and shape connection obsolete plus the mid region from the intermediate ventricle to the base up to the myocardial fringe. This same images of 21 subjects are compared with the manual delineation method by locating the center manually. Mean and Standard deviation is calculated for the basal, mid and apex regions of the LV for auto and manual segmentation. Bland –Altman investigation is performed for End Diastolic Measurements in volume (EDV) with the existing investigations and found to be more close to the ground truth results and superior than the previously enduring methods. To conclude the projected segmentation process truthfully locates and segments the LV which trials the one hundredth of blood pour. EDV measurements are established with less computational time to find the patient’s heart failure with myocardial Infarction.Objective: To spot the cardiac maladies triggered owed to stumbling block of blood by dissection of left Ventricle with MRI image.

Published: March 2018

Mobile Ad hoc Networks (MANETs) is the interconnection of several self-energy dependent mobile nodes. It is one of the self-configured and infrastructure less network. In MANET the issues are security, Quality Of Services, Congestion etc. The major issue of MANET is to control the congestion. Congestion means the network capacity is larger than the no of packets transmitted across the network. In this paper, an effort has been made to evaluate and analyze the performance of the network by means of comparing two on-demand reactive routing protocols such as AODV [Ad-hoc On-demand Distance Vector] and DSR [Dynamic Source Routing] with each other along with also by comparing with DSDV [Destination Sequenced Distance Vector], which is a proactive routing protocol. The comparison is also being made under the light of two queue management techniques such as RED (Random Early Detection) and Droptail. A gateway discovery algorithm is being used by both AODV and DSR routing protocols, which uses the mechanism of connecting mobile nodes through gateway, however Bellman-Ford algorithm is being used by DSDV which uses the concept of including freedom from loops in the routing table. By means of simulation through NS-2 network simulator by varying the number of nodes, we observe that the performance differentials of AODV, DSR, and DSDV routing protocols are directed to foremost performance differentials to guarantee QoS for both of these protocols in RED and Droptail queue management techniques. There is a lot of queue management approach to minimize the congestion rate and transfer the data successfully to the destination. Two queue management techniques popularly used to manage queues in MANets are Active queue management and Passive queue management. Active queue management is widely used and RED is the most popular approach which gives low average delay, high throughput and lower packet drop rate. But RED algorithms have some drawback. So here we are using a hybrid approach, named as MRED by means of combining the features of both RED and ECN to overcome the drawbacks of RED.

AbstractIntroduction. The number of caesarean sections has drastically increased and thus arose the idea to examine the effect of the type of anesthesia on the neonates. The objective was to compare vital parameters in the neonates, born under general and spinal anesthesia.Method. A total of 120 patients with need for caesarean section have been divided in two groups of 60, of which the first was lead in general and the second one in spinal anesthesia. The first one was given propophol (2.0-2.5 mg/kg/tt) and succinil colin (1-1.5 mg/kg/tt). The anesthesia was lead with fentanil 0,005 mg/kg/tt and rocuronium bromide 0.4-0.6 mg/kg/tt. O2:N2O was 3:3 l/min. The second group was lead in spinal anesthesia. 2-3 ml Bupivacain 0.5% was spinally applied between L2-L3. Apgar score was defined in the neonates in the first and fifth minutes. The acido-basic status of the neonate was examined through pH values in the blood and the base excess.Results. In the first minute after birth giving with Apgar, 8 newborns 37(61,67%) were born to the group of patients with SA and 29 (48.33%) to the group of patients with GA. In 11 (18.33%) newborns born to the patients led with SA had Apgar score of 9-10, while only 3 (5%) of the newborns born to the patients led with GA had Apgar score of 9-10. Similar ratio was noted in the fifth minute after birth. Ph of the newborns’ blood as well as the base excess (BE) demonstrated significantly lower values in the group of patients led with SA than in the group of patients led with GA. Ph = 7.33 vs 7.37; BE=-4.57±1.8 vs -2.96±2.3.Conclusion. The newborns from the second group had significantly higher Apgar scores than those in the first group. The newborns’ relative acidose (lower SpO2and BE) did not affect the newborns’ Apgar score in the first and fifth minute.

AbstractIntroduction. Two-stage revision surgery for infected knee endoprosthesis using antibiotic articulating spacer is the best possible standard in most of the orthopedic centers worldwide.Methods. In the period from 2008 to 2012 we treated 21 patients with infected knee endoprosthesis. We used a single protocol for diagnosis and treatment of infection which included x-ray examination, serological examination (sedimentation and CRP), fine needle aspiration of the joint with further microbiological and biochemical examination of the smear. The surgical treatment was consisted of taking samples for microbiological and histological examination, removing the implanted endoprosthesis and excision of the avascular and necrotic tissue, implantation of articular antibiotic spacer. The postoperative steps included administration of parenteral antibiotics according to the previously made antibiogram in a two-week period followed by two oral antibiotics (ciprofloxacin and rifampicin) in the next four to six weeks. The second-stage procedure was performed when there were no clinical and serological signs of infection. Removing of the antibiotic spacer and implanatation of primary or revision prosthesis according to bone deficit was performed.Results. In one patient the procedure was carried out three times, arthrodesis of the knee joint was made in one patient and in nineteen patients reimplantation was performed. One patient after reimplanation had reinfection after 6 months. The follow-up period of the patients was 36 months. The functional results according to the Knee society score: preoperative 36, postoperative 74.Conclusion. Two-phase treatment is satisfactory in treatment of periprosthetic joint infection. Articulated antibiotic loaded bone cement spacer is superior in eradication of local infection. It allows partial function of the joint and makes easier the second surgical intervention. Infection with Staphylococcus aureus is difficult to be treated with a higher percent of recidives.

AbstractEfficiency of dye-sensitized solar cell (DSSC) depends on several interrelated factors such as type and concentration of dye, type and thickness of photoelectrode and counter electrode. Optimized combination of these factors leads to a more efficient cell. This paper presents the effect of these parameters on cell efficiency. TiO2nanoporous thin films of different thicknesses (5 μm to 25 μm) were fabricated on indium doped tin oxide (ITO) coated glass by doctor blading method and characterized by inverted microscope, stylus surface profiler and scanning electron microscope (SEM). Natural organic dye of different concentrations, extracted from turmeric, was prepared with ethanol solvent. Different combinations of dye concentrations and film thicknesses along with different types of carbon catalyst have been investigated by I-V characterization. The result shows that the cell made of a counter electrode catalyst material prepared by candle flame carbon combined with about 15 μm thick photoelectrode and 100 mg/mL dye in ethanol solvent, achieves the highest efficiency of 0.45 %, with open circuit voltage of 566 mV and short circuit current density of 1.02 mA/cm2.

Abstract
Cerium oxide nanoparticles (CONPs) were prepared using ultrasound assisted leaf extract of Prosopis juliflora acting as a reducing as well as stabilizing agent. The synthesized CONPs were characterized by ultraviolet-visible absorption spectroscopy (UV-Vis), particle size analyzer (PSA), Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and high-resolution transmission electron microscopy (HRTEM). From the UV-Vis analysis, the optical band gap of the prepared CONPs (Eg = 3.62 eV) was slightly increased as compared to the bulk ceria (Eg = 3.19 eV). The phytochemicals in the extract reduced the particle size to 3.7 nm ± 0.3 nm, as it is evident from the PSA. FT-IR results confirmed the Ce-O stretching bands by showing the peaks at 452 cm-1. The Raman spectrumshowed a characteristic peak shift for CONPs at 461.2 cm-1. XRD analysis revealed the cubic fluorite structure of the synthesizednanoparticles with the lattice constant, a of 5.415 Å and unit cell volume, V of 158.813 Å3. XPS signals were used to determine the concentration of Ce3+ and Ce4+ in the prepared CONPs and it was found that major amount of cerium exist in the Ce4+ state. HRTEM images showed spherical shaped particles with an average size of 15 nm. Furthermore, the antibacterial activity of the prepared CONPs was evaluated and their efficacies were compared with the conventional antibiotics using disc diffusion assay against a set of Gram positive (G+) bacteria (Staphylococcus aureus, Streptococcus pneumonia) and Gram negative (G-) bacteria (Pseudomonas aeruginosa, Proteus vulgaris). The results suggested that CONPs showed antibacterial activity with significant variations due to the differences in the membrane structure and cell wall composition among the two groups tested.

Published: March 2018

Abstract
The authors have deposited the diamond-like carbon (DLC) films by radio frequency inductively coupled plasma enhanced chemical vapor deposition (RF ICP PECVD) method. The investigated DLC films with different sp3 fraction content were deposited on polished and textured silicon substrates. The sp3 fraction content of the deposited DLC films was ranging from 35 % to 70 % and was estimated from acquired Raman scattering spectra (excitation wavelength: 325 nm and 514.5 nm). The measurements of field emission characteristics were carried out in diode configuration. Emission properties of the DLC films were calculated from Fowler-Nordheim plots. The calculated electric field enhancement factor β was ranging from 56 to 198 for the DLC films deposited on polished substrates and from 115 to 445 for films deposited on textured substrates. The surface of the DLC films was observed by scanning electron microscope (SEM) after field emission measurements. The acquired SEM images reveled that the activation of field emission from the DLC films is connected with generation of structural damage to the DLC films.

Published: March 2018

Abstract
We have studied the band structure and the band gap closure of TlInSe2 under pressure in the range of 0 GPa to 21 GPa, by employing the first-principles method based on the density functional theory. We discuss the possible metallic transition in the tetragonal phase of TlInSe2 crystal. Our calculation results show that the value of the pressure at the crossover from the direct to the indirect gap is found to be 8 GPa. The “semiconductor-metal” transition is determined to occur at 14 GPa. The study of the pressure effect on the effective masses for semiconductor state shows that with increasing pressure, the effective masses of holes and electrons decrease and the anisotropy of effective masses of holes is weakening.

The Role of Trust in Political Systems. A Philosophical Perspective
Authors: Weinert Friedel 
Published: March 2018

Abstract
The paper analyzes the question of whether trust is an essential condition for the functioning of social and political systems; it approaches the issue from a philosophical perspective. Trust appears in both interpersonal relationships (interpersonal trust) and in societal and political institutions (social and political trust, respectively). In the political literature trust is sometimes characterized as ‘an expectation of continued value’. Although the same literature distinguishes social from political trust, the thesis advanced here is that, logically, all forms of trust must be characterized as an inductive generalization from past experience to future expectations of the continuation of some specifiable utilities (goods, services). As such, trust suffers from Humean reservations about inductive inferences. Trust as an expectation of the continued provision of utilities, on the institutional level, will be characterized as a first-order sort of trust. It can be disappointed without necessarily threatening the continuation of a given institution, especially if there is no alternative service provider. But trust as an expectation of the continued functioning of democratic mechanisms will be characterized as a second-order sort of trust. The paper will argue that the second-order kind of trust is essential for the functioning of democracies.

Published: March 2018

Abstract
Wearable devices that monitor our vital signs have been gaining more importance with each year. Non-invasive, continuous, accurate and precise blood pressure assessment method integrated in a wearable is a multidisciplinary challenge. This work presents an electrical bioimpedance (EBI) unit for multi-frequency measurements on pulsating artery for central aortic pressure (CAP) estimation. The developed device provides low complexity in the electronics design with a frequency range between 1 kHz and 200 kHz. It is able to register the impedance of blood vessel volume change simultaneously at different locations. Experiments were carried out in vivo by using the four-electrode configuration on human thorax, axillary artery and radial artery. Preliminary results show the applicability of the proposed impedance spectroscopy system to measure blood vessel volume changes. The impedance data can be later interpreted into the aortic blood pressure wave by using a generalized transfer function. In addition, experimental test-phantom and electrode design are introduced for testing purposes of the impedance system.
