Calcium Urolithiasis : Role of Lipid Peroxidation and Antioxidants

The aim of present study was to assess the levels of malondialdehyde (marker of lipid peroxidation), vitamin E and selenium (natural antioxidants) in serum samples of patients with calcium containing kidney stones and in control subjects in order to observe their role in the pathogenesis of calcium containing kidney stones. For this purpose 80 subjects including 40 confirmed cases of calcium containing kidney stones and 40 age and gender matched control subjects with no personal or family history of urolithiasis were recruited from the OPD of Liaquat University Hospital Jamshoro and Isra University Hospital Hyderabad during June 2012 to December 2012. Serum malondialdehyde (MDA), vitamin E and selenium levels were measured by spectrophotometric methods using commercially available kits. Serum MDA levels were found to be significantly higher (p<0.001) and of vitamin E and selenium significantly (p<0.001) lower in calcium containing kidney stone patients as against the control subjects. A weak positive correlation (which was not statistically significant) was seen between serum MDA and vitamin E levels and between MDA and selenium levels. The results of present study suggest that lipid peroxidation owning to decreased amounts of antioxidants seems to play a major role in the pathogenesis of calcium containing kidney stones.
MODEL PREDICTIVE CONTROL FOR PATH TRACKING OF A TILTROTOR UAV

In this paper a model predictive control is used to solve the path tracking problem of a tiltrotor unmanned aerial vehicle. The MPC controller is based on the linear error model of a tilt-rotor and the linearization is performed around a generic trajectory. The non-linear system is obtained via Euler-Lagrange formulation, taking into account eight degrees of freedom of the vehicle. The control action is calculated via an optimization problem where a cost function is solved with input and output constraints. To prove the effectiveness of the controller some simulations are carried out, considering constant disturbances at different instants of time, and modeling error.

Optimization of Facade Design for Daylighting and View-to-Outside A case study in Lecco , Lombardy , Italy

Minimizing the impact of shading devices on the view to the surrounding view is essential for indoor spaces that overlook exceptional scenery and views. Building facades that overlook such views require a special care not to obstruct the view to the outdoors. At the same time, poorly designed shading devices can result in high solar penetration and glare probability affecting the ability of the users to enjoy the outdoor view. In this paper, we analyze the effect of adding different shading devices and configurations to a south façade for a workshop space in Lecco, Italy. A parametric model of five types of shading devices was analyzed for the daylighting, glare and view performance. The trade-off between the objectives and the cases that achieved satisfactory performance in all three criteria were presented.
On positive invariance for delay difference equations

In this paper a new concept of set invariance, called D-invariance, is introduced for dynamical systems described by delay difference equations. We will be interested in the definition and computation of such invariant sets in a specified bounded region of the state-space. The Minkowski algebra will be used to define mappings over the set of compact sets in direct relationship with the invariance of time-delay systems. Set-iterates based on these mappings can be used for the construction of a non-decreasing sequence of D-invariant sets.
Supplemental Materials ( Online Appendix ) Politicians in the Line of Fire : Incivility and the Treatment of Women on Social Media Additional Information on Data Collection

We retrieved messages from the Twitter platform using the public streaming API during a period of one month for each country. For Canada, data collection took place from 7:00 AM to 3:00 AM, Eastern time, using a script launched automatically every day. The period of collection ranges from April 24 to May 26, 2017. For the US Senators, the platform was streamed in real-time between May 27 and July 5, 2017, during the same hours each day. In total, we collected 551,373 tweets addressed to Canadian politicians, and 5.6 million targeted at US Senators. There were no interruptions of service during that period. The Twitter streaming API is limited to 1% of the total quantity of statuses posted on the site at any given point (for detailed discussions, see Morstatter et al. 2013; Morstatter, Pfe er, and Liu 2014; Joseph, Landwehr, and Carley 2014). Since we relied upon very speci c search lters—the handles used by each politician—we generally remain well below the rate limits. This means that our data represent not a sample of tweets during that period, but virtually all the messages matching our search criteria. More speci cally, Twitter reports the number of statuses that could not be retrieved when exceeding the rate limit. In total, 1,952 messages were not retrieved in Canada due to rate limits (about 0.4% of the total corpus size), and 81,322 for the United States (about 1.4% of the total). In other words, we were
DE-NOISING OF GROUND MOTION RECORDS USING SHORT-TIME MATRIX PENCIL METHOD

Recorded acceleration histories are known as one of the most valuable information remained from past earthquakes in the field of earthquake engineering and engineering seismology. These acceleration histories are generally contaminated with high level of noises masking the important information embedded in such records. Due to low signal to noise ratio (SNR) and non-stationary characteristics of the noises, conventional de-noising methods are not capable of distinguishing the original part of the seismic signals. Therefore, several advanced methods such as sliding discrete Fourier transform (SDFT), discrete wavelet transformation (DWT) and Hilbert transform (HT) were proposed to correct the noisy signals. One of the most important deficiencies associated with the state-of-the-art approaches is their high level of sensitivity to the frequency content of recorded signals, sampling rates, and noise parameters. Therefore, a single reliable filtering approach might not be feasible for a wide range of signal and noise parameters. To fill this technical gap, this paper proposes a de-noising approach based on the short-time matrix pencil method (STMPM) that decomposes the recorded signals in a sliding window into time-indexed complex frequencies. The noise contents of each record are recognized and eliminated based on the real part of the complex frequencies (known as damping factors), which has low sensitivity to the parameters of signals and noises. The robustness of the proposed approach is validated through the use of two noisy seismic records. 1 MSc Student, Department of Civil and Environmental Engineering, K.N.

Nanostructures at surfaces from substrate-mediated interactions

Recent theoretical and experimental studies indicate that adsorbate-adsorbate interactions mediated by a solid surface can be significant enough to influence the formation of nanostructures during thin-film epitaxy. Here, we show that these electronic interactions lead to the formation of repulsive barriers surrounding small adsorbate islands at surfaces. The dependence of these barriers on island size and shape actuates sharp islandsize distributions, which can be manipulated by changing growth conditions to yield selected island sizes and shapes. The existence of these interactions opens new prospects for engineering nanostructures at surfaces.
Towards a standardised methodology for inventorying and monitoring Mediterranean wetlands using Earth observation

Knowledge and expertise on using Earth observation (EO) technology are being exchanged in the framework of several projects in order to establish a standardized methodology aiming at inventorying and monitoring Mediterranean wetlands at site, catchment, national, and regional levels. The strong points of EO include the enhanced spatial, geometric and spectral characteristics of the new satellite sensors, the possibility to choose from a variety of sensors in respect to mapping scales and nomenclatures, and the cost effectiveness of the approach. The aim of this paper is to demonstrate how EO can assist the establishment of a comprehensive methodological approach to achieve a multilevel inventory and monitoring of Mediterranean wetlands. ISARS/NOA Remote Sensing Group is employing hybrid data processing methodologies, combining visual and computer assisted photointerpretation, as well as advanced computer methods using spectral/textural/ contextural classifications and change detection to define the status and trends in wetland ecosystems.
Impact of Ag 2 + stress on growth and phytochemical production by Spirulina platensis

The biocidal effect of silver is particularly well known and the term, oligodynamic activity was coine d for this phenomenon. Silver is highly toxic to bacteria, and that toxicity seems to be accentuated when silver is delivered by a nanoparticle. In context of this the effect of Ag ion was investigated on S. platensis. pH (=9.0±0.2) and temperature (32 C) was optimized. Under these conditions, Ag 2+ ion stress helped in growth at concentration of 1.0mg/ml followed by 0.5mg/ml as compared to contro l samples. The biomass production, protein synthesi s, carbohydrate and chlorophyll contents were also det ermined. The specific phytochemical tests were conf irmed presence of glycosides, terpenoids, phenolics, carb ohydrates, amino acid, steroids, flavanoids, alkalo id and phenolics. Despite of biocidal activity of silver a t higher concentrations this study suggests that Ag 2+ at concentration of 1.0mg/ml may be added in the cultu re medium of S. platensis for optimum growth and pr oduction of value added products.
The Geometry of classical change of signature

The proposal of the possibility of change of signature in quantum cosmology has led to the study of this phenomenon in classical general relativity theory, where there has been some controversy about what is and is not possible. Here we present a new analysis of such a change of signature, based on previous studies of the initial value problem in general relativity. We emphasize that there are various continuity suppositions one can make at a classical change of signature, and consider more general assumptions than have been made up to now. We confirm that in general such a change can take place even when the second fundamental form of the surface of change does not vanish.
2-D ANALYSIS OF SALT DESORPTION MECHANISM AT SMOOTH CONCRETE STRUCTURE SURFACE

Salt desorption mechanism is one of the fastest environmental actions which affects concrete structures subjected to chloride attack. 2-D numerical simulation analysis of salt desorption mechanism at concrete surface has been conducted. To conduct this numerical analysis, experimental works have been conducted to get some empirical constants. Desorption mechanisms, water thickness distribution, water velocity, and methods to measure and to calculate the amount of washed away salt are discussed and an empirical function to characterize salt desorption is proposed.

A comparative study on renal function parameters and age in females with and without pre-eclampsia in a tertiary health care setup

Background and objective: Pathogenesis of preeclampsia is known to be associated with renal dysfunction. But the best suited renal function parameter to quantify pathogenesis of this clinical condition is unclear. This study is aimed to assess the renal parameters in preeclampsia. Materials and Methods: 185 consecutive mothers in 20th week of gestational period were enrolled into the study. Based on the presence or absence of preeclampsia they were divided into two subgroups: Group A (82 mothers with preeclampsia) and Group B (103 normotensive mothers). Results: In all the mothers serum urea, serum creatinine and serum uric acid was measured. Serum uric acid of group A was very significantly higher compared to group B ( p < 0.0001). Serum urea and serum creatinine of group A was just significantly higher compared to group B (p<0.05). Conclusions: Among the renal function parameters measured uric acid was better suited in assessing renal dysfunction in mothers with preeclampsia.
Neurological Aspects of SARS-CoV-2 Infection: Mechanisms and Manifestations

The human infection of the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a public health emergency of international concern that has caused more than 16.8 million new cases and 662,000 deaths as of July 30, 2020. Although coronavirus disease 2019 (COVID-19), which is associated with this virus, mainly affects the lungs, recent evidence from clinical and pathological studies indicates that this pathogen has a broad infective ability to spread to extrapulmonary tissues, causing multiorgan failure in severely ill patients. In this regard, there is increasing preoccupation with the neuroinvasive potential of SARS-CoV-2 due to the observation of neurological manifestations in COVID-19 patients. This concern is also supported by the neurotropism previously documented in other human coronaviruses, including the 2002–2003 SARS-CoV-1 outbreak. Hence, in the current review article, we aimed to summarize the spectrum of neurological findings associated with COVID-19, which include signs of peripheral neuropathy, myopathy, olfactory dysfunction, meningoencephalitis, Guillain-Barré syndrome, and neuropsychiatric disorders. Furthermore, we analyze the mechanisms underlying such neurological sequela and discuss possible therapeutics for patients with neurological findings associated with COVID-19. Finally, we describe the host- and pathogen-specific factors that determine the tissue tropism of SARS-CoV-2 and possible routes employed by the virus to invade the nervous system from a pathophysiological and molecular perspective. In this manner, the current manuscript contributes to increasing the current understanding of the neurological aspects of COVID-19 and the impact of the current pandemic on the neurology field.
Yaw Angle Effect on the Aerodynamic Performance of Hatchback Vehicle Fitted with Combo-Type Spoiler

Article history: Received 5 February 2018 Received in revised form 12 March 2018 Accepted 20 March 2018 Available online 15 April 2018 This study investigated the effect of yaw angle on the aerodynamic performance of hatchback vehicle model fitted with a spoiler featuring a configuration combining the wing and strip spoiler designs. To date, majority of the tests performed on spoilers were done in a straight-ahead driving condition. However, the effect of spoiler is most demanded during cornering for stability reason. A RANS-based Computational Fluid Dynamics (CFD) method was used to simulate the flow. Validation of the method was carried out by comparing the numerically obtained results with the experimental data. The findings show that both the drag coefficient, Cd, and lift coefficient, Cl had increased when the vehicle was subjected to higher yaw angle. The wing part of the spoiler did performed in favour of reducing the Cl, but its contribution to the overall Cl was only about 4.28%. The main body parts contributed to the decrease in Cd and Cl are the front and underbody, respectively.
THE EFFECT OF IMPLANT ANGLE AND RESIST SHADOWING IN SUBMICRON IMPLANT TECHNOLOGY

As the integrated circuit (IC) fabrication industry gears up to volume manufacturing of 90nm technology node and beyond, there are issues still need to be addressed at the lower technology nodes such as 0. 13μm and 0. 22μm. The lateral scaling has faces limitation in dealing with the profiles encroachment due to resist shadowing for well implant process. Driving the ion implant angle to near normal regime is a potential solution for the above concern. Nevertheless, this approach will lead to severe dopant channeling. Thus, there is an interest to study the impact of implant angle and resist shadowing on sub-micron technology. The goal for this work was to determine the feasibility of a novel approach to forming a well with near 0° tilt implantation. To achieve this, there is a requirement to find a compromise between dopant channeling and resist shadowing for the high-energy implantation in low tilt angle regime. This study will focus on low tilt angle high-energy implantation since this implant regime has more severe issues on the resist shadowing and dopant channeling. All implant processes in the experiments were performed by spin disk endstation GSD batch implanter system. There are two experiments to evaluate the impact of implant angle. The first experiment is to evaluate the uniformity of the dopant profile across the wafer (implant uniformity) with the intention to find the optimum implant tilt angle with acceptable implant uniformity. In this work, all sample wafers have been prepared by performing single and quad implantations with implant angle 0° to 7°. The characterization of implant uniformity has been done by thermal wave measurement on the sample. For low tilt high-energy implantation, the implant uniformity is dominated by the implant beam angle error. In terms of the dopant profile uniformity across the wafer, tilt 2° or higher tilt angle implant has been proposed for single implant process. Meanwhile, quad 4 and quad 5 have been proposed for quad implant. The second experiment in this work involves fabrication of the novel well structures with tilt 2° implant to create

However, there is considerable uncertainty surrounding the impacts that integration of these technologies will have on future aircraft. In this paper, the foundation is established for a physical experiment selection methodology that aims to maximize the reduction of uncertainty and the maturation of technologies. Throughout the methodology formulation, a case study is described for an active flow control technology currently under development.
Design of Ka-band half mode substrate integrated waveguide (HMSIW) mixer

In this paper, a half mode substrate integrated waveguide (HMSIW) mixer at Ka-band is proposed. A newly developed 3-dB cruciform HMSIW coupler was employed to add LO and RF signal on schottky diodes. Size of the mixer is more compact than traditional narrow-wall aperture coupling SIW or HMSIW configuration mixer. The mixer was designed and fabricated on Roggers 5880 substrate with beam lead schottky diodes. In experimental test, conversion loss was measured in frequency range from 34 to 38 GHz under different LO power. The conversion loss of 8.2 dB was reached at 36 GHz.
