Association Between Particulate Air Pollution and Systemic Inflammation in Persons with Ischemic Heart Disease (2009)

ISEE-0555 Background and Objective: Persons with cardiovascular disease are vulnerable to the effects of particulate air pollution (PM) on health. Systemic inflammation has been suggested to mediate the effects of PM on cardiovascular health. Our aim was to evaluate the association between outdoor levels of PM and systemic inflammation among ischemic heart disease patients. Material and Methods: Daily levels of fine particles (PM2.5; diameter < 2.5 μm), coarse particles (PM10-PM2.5; diameter 2.5–10 μm) and particle number concentration (PNC) were measured at a central outdoor measurement site in Kotka, Finland, between November 2005 and May 2006. Absorption coefficient (Abs) an indicator of elemental carbon was determined to obtain an estimate of combustion derived particles. Concurrently with the air pollution measurements, subjects with coronary heart disease were followed for 6 months with biweekly clinical visits. Blood levels of interleukins −8 and −12 (IL-8 and IL-12), C-reactive protein (CRP) and fibrinogen (Fb) were determined to be used as indicators of systemic inflammation. Associations between PM and the levels of Fb and log-transformed levels of IL-8, IL-12 and CRP were analyzed using generalized additive models adjusting for apparent temperature. Results: Daily average concentrations of PM2.5 and PNC were 8.3 μg/m3 and 5000 cm−3, respectively. PM2.5 was positively associated with CRP and IL-12. Effect estimates for interquartile increases in PM2.5 were 30.4% (1-day lag, 95% confidence interval (CI) 4.2–56.6%) for IL-12 and 5.0% (5-day avg., 95% CI 1.0–9.1%) for CRP. In addition, coarse particles were positively associated with Fb, PNC with IL-8, and Abs with IL-12 and CRP. Conclusions: Even low levels of ambient PM are associated with systemic inflammation, a risk factor for coronary heart disease.
Occurrence of Acquired Tracheoesophageal Fistula Due to Excess Endotracheal Tube Cuff Volumes - A Case Report - (2013)

Endotracheal tube cuff volume and pressure require constant monitoring to prevent tracheal injury. Acquired tracheoesophageal fistula is common from complications of mechanical ventilation as a result of pressured necrosis of the tracheoesophageal wall by endotracheal tube cuff. It still represents a life-threatening condition, especially when the diagnosis is being delayed. We present our modest experience through an acquired TEF patient who had an excessively enlarged cuff diameter on chest radiogram in order to consider the potential of using radiological-measured cuff diameter as a simple technique for predicting tracheal damages. Although the cuff pressure was monitored with a manometer by the medical team, it was possible that the tube cuff was excessively enlarged. Proper procedures for preventing the tracheal damage by cuffs include the following: monitoring of endotracheal cuff pressure and volume, observation of cuff size on the chest radiogram, and being mindful and attentive for possibilities of misjudgements by manometer or medical teams.
Electrolyte Chemistry Enables Simultaneous Stabilization of Potassium Metal and Alloying Anode for Potassium‐Ion Batteries (2019)

Alloying anodes are promising high-capacity electrode materials for K-ion batteries (KIBs). However, KIBs based on alloying anodes suffer from rapid capacity decay due to the instability of K metal and large volume expansion of alloying anodes. Herein, the effects of salts and solvents on the cycling stability of KIBs based on a typical alloying anode such as amorphous red phosphorus (RP) are investigated, and the potassium bis(fluorosulfonyl)imide (KFSI) salt-based carbonate electrolyte is versatile to achieve simultaneous stabilization of K metal and RP electrodes for highly stable KIBs. This salt-solvent complex with a moderate solvation energy can alleviate side reactions between K metal and the electrolyte and facilitate K<sup>+</sup> ion diffusion/desolvation. Moreover, robust SEI layers that form on K metal and RP electrodes can suppress K dendrite growth and resist RP volume change. This strategy of electrolyte regulation can be applicable to other alloying anodes for high-performance KIBs.
[S100B: astrocyte specific protein]. (2006)

The S100B is a Ca2+ binding proteins of EF-hand type and is produced primarily by astrocytes in the central nervous system. This protein has been implicated in the Ca2+-dependent regulation of a variety of intracellular functions such as protein phosphorylation, enzyme activities, cell proliferation and differentiation, dynamics of cytoskeleton constituents, structural organization of membranes, intracellular Ca2+ homeostasis, inflammation, and protection from oxidative cell damage. Recent studies suggest that released S100B exerts paracrine and autocrine effects on neurons and glia. On the other hand, elevations of S100B levels in blood or cerebrospinal fluid have been observed in patients with Alzheimer's disease, Down's syndrome, amyotrophic lateral sclerosis, multiple sclerosis, schizophrenia, depression, cerebral stroke and traumatic brain injury, and the levels have reached micromol/L-order at focal regions. It has been documented that the excessive S100B promotes the expression of inducible nitric oxide synthase or pro-inflammatory cytokines and exhibits detrimental effects on neurons. On studies using some animal models of the cerebral stroke or Alzheimer's disease, it is suggested that the excessive S100B produced by activated astrocytes precedes neurodegenerations. Authors discussed the relationship between neurological disorders and the S100B.

Ketamine is associated with minimal, clinically insignificant hemodynamic changes in sedated, mechanically ventilated children with pulmonary hypertension.
Mechanism of Electrodeposition of PbO2 at a Pt Sheet/Rotating Disk Electrode (2002)

The electrodeposition of PbO2 from aqueous solutions of Pb(II) species at Pt sheet and Pt rotating disk electrodes was carried out using cyclic voltammetry. Experimental results have shown that the electrodeposition of PbO2 has several steps. The first step is the hydration of Pb(II) species in the bulk solution. At the next step, these hydrated species adsorb on the electrode surface. At the third step the adsorbed species is oxidized electrochemically to form an intermediate product, Pb(OH), which is further oxidized electrochemically to form another intermediate product, Pb(OOH). At the final step, this product dehydrates to form PbO2.
Study of LSPR-enhanced absorption for solar cell applications: preliminary results (2009)

The Localized Surface Plasmon Resonance (LSPR) phenomenon exhibited in nano-particles, embedded in a dielectric medium has recently been shown to enhance the absorption as well as the photo-generation effect in several lightsensitive structures including solar cells and photo-diodes. The origin of this enhancement has not yet been sufficiently clarified as there appear to be several mechanisms at play, depending on the particular device structure and configuration. We have conducted computer simulation studies on the absorption enhancement in a silicon substrate by nano-shell-related LSPR, based on a Finite Difference, Time-Domain (FDTD) Analysis. Preliminary results of this study show significant enhancement of up to 10X in the near band gap spectral region of Si, using 40-100nm diameter nano-shells. The enhancement was studied as a function of the metallic Shell thickness, the thickness of an externally coating layer of SiO<sub>2</sub>, as well as of various nanoshell shapes. The results suggest that the main enhancement mechanism in this case of tubular nanoshells embedded in Si substrate, is that of field-enhanced absorption caused by the strongly LSPR-enhanced electric field extending into the Silicon substrate.
Pharmacokinetics of Morphine Sulfate Orodispersible Tablets and Bioequivalence with Immediate-Release Oral Morphine Sulfate Formulations in Healthy Adult Subjects Under Fasting Conditions: Single-Dose Comparative Bioavailability Studies (2022)

The ODTs were safe, well tolerated, and showed similar pharmacokinetics to those of the reference formulations. The development of a range of doses of morphine sulfate ODTs may provide a new alternative for the oral administration of immediate-release morphine for pain management in pediatric, geriatric and adult populations with swallowing problems.
P2‐166: Atomic structure of the PHF core C‐terminus (2008)

The major constituent of Alzheimer's disease paired helical filaments (PHF) core is intrinsically disordered protein (IDP) tau. In spite of a considerable effort, insoluble character of PHF together with inherent physical properties of IDP tau have precluded so far reconstruction of PHF 3-D structure by X-ray crystallography or NMR spectroscopy. Using monoclonal antibody MN423 specific to the tertiary structure of the PHF core, the in vivo PHF structure was imprinted into recombinant core PHF tau. Crystallization of the complex led to determination of the structure of the core PHF tau protein fragment 386TDHGAE391 at 1.65 Å resolution. Here we present first crystallographic study of PHF core C-terminus. PHF core C-terminal hexapeptide 386TDHGAE391 has a form of a loop, which is not stabilized by any direct intrachain hydrogen bonds (Fig. 1). As the MN423 was raised against a compact, protease resistant core PHF tau, the hexapeptide directly interacting with MN423 is an integral part of the compact PHF core. Its close association with the compact PHF core suggests a potential role of the C-terminal core peptide in PHF assembly. The approach presented here suggests a new possibility in crystallographic analysis of intrinsically disordered proteins involved in pathogenesis of neurodegenerative diseases. It is reasonable to expect that this approach will help to reveal the structural principles underlying the tau protein assembly into PHF and possibly will facilitate rationale drug design for inhibition of Alzheimer neurofibrillary changes.
Bergetto - The Prodigal Son Abroad in 'The Iron Age'. (2017)

This paper examines the character of Bergetto from John Ford’s play, ’Tis Pity She’s a Whore , and suggests that the foolish figure is an evolution of the humanum genus stock-character. As such, Bergetto encapsulates moral and ethical paradigms, most notably the parable of the prodigal son and Aristotle’s golden mean. In the morality tradition the representative of humanity is aided and hindered by opposing forces of Virtue and Vice, led into sin by the latter before being persuaded to repent by the former, and thus finding the path to salvation. Aristotle’s ethical vision of virtue as a moderate point between vices of excess and defect was frequently overlaid upon this psychomachian concept; fallen humanity becoming the vice of defect and the forces of evil that seek to corrupt him or her the vices of excess. In Ford’s debased Parma there are no virtuous figures (with the possible exception of Bergetto’s would-be wife Philotis) and Bergetto offers the sole representative of frail humanity. Surrounded in a city that has been overrun by vice and excess, he is ultimately murdered moments before his marriage, an event that often signified redemption in the Stuart period. Ford uses Bergetto to exploit and pervert traditional morality themes in order to portray a society so corrupt that innocence and virtue cannot survive. Bergetto therefore plays a vital and underestimated role in conveying the depth of this dark vision.
Video see-through design for merging of real and virtual environments (2002)

A head mounted display (HMD) that is optically opaque with respect to the outer world can be provided with see-through capability by mounting video cameras to the outside of the helmet. Stereoscopic views of the physical space surrounding the wearer are captured by the video cameras, and are projected to the display screens inside the HMD. The conditions necessary for mounting the cameras to a pre-existing, non-see-through HMD are described, and the advantages and disadvantages of different mounting schemes are discussed, together with the design of the video cameras lenses to be used with this specific application.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Inquiry-Based Learning Through Image Processing [dsp Education] (2011)

As in many states, educators in Pennsylvania school districts are strongly encouraged to incorporate science, technology, engineering, and mathematics (STEM) activities and applications into the high school classroom. Incorporating topics on engineering into the high school curriculum poses a challenge for the educator, however, since most science textbooks and teacher resources (for levels prior to college) include little if any engineering content or activities [1]. Therefore, teachers must consult alternative resources if they intend to include engineering concepts in the classroom. With recent educational cuts and standardized testing stress, educators have little time to seek out such resources.
Penyediaan dan Pencirian Membran Pertukaran Kation dengan Resin untuk Proses Elektrodialisis (2012)

Elektrodialisis merupakan suatu proses yang menggunakan perbezaan keupayaan elektrik sebagai daya penggerak yang menyebabkan pergerakan ion-ion dalam sesuatu elektronit. Membran yang digunakan dalam proses ini akan membenarkan sama ada cas-cas positif atau negatif sahaja melaluinya bergantung kepada kumpulan berfungsi yang terikat pada membran. Objektif projek penyelidikan ini adalah untuk menghasilkan membran pertukaran kation yang digunakan dalam proses elektrodialisis. Membran-membran pertukaran kation yang dihasilkan terbahagi kepada lima jenis, dan diberi nama sebagai BERL–30, 40, 50, 60, dan 70. Kelima-lima jenis membran ini berbeza dari segi kandungan resin yang berfungsi sebagai vektor pertukaran cas kation. Di samping penyediaan membran, penyelidikan ini juga meliputi aspek pencirian membran tersebut serta perbandingan dengan membran komersial. Kriteria yang dikaji adalah ketebalan membran, sifat kebolehtelapan membran, kapasiti pertukaran ion, kapasiti kepekatan ion kumpulan berfungsi, morfologi struktur membran, ujian kestabilan kimia dan kandungan air membran. Secara keseluruhannya, didapati peratus kandungan resin yang tinggi boleh meningkatkan kapasiti pertukaran ion, peratus kebolehtelapan membran serta kapasiti kepekatan ion kumpulan berfungsi. Antara membran yang dihasilkan, membran pertukaran kation jenis BERL–70 merupakan membran yang berpotensi dalam penggunaan proses elektrodialisis. Kata kunci: Membran pertukaran kation, polisulfona, resin pertukaran ion, ciri-ciri membran, elekrodialisis The objective of this work is to prepare an anion exchange membrane from polysulfone binder–ion exchange resin, which can be used in electrodialysis process. The cation exchange membranes were prepared by the solution casting method. The prepared anion exchange membranes are different from the conventional cation exchange membranes because its functional group is not derived from chlorosulfonic acid but from the absorption of anion exchange resins. The content of resins in each set of the prepared cation exchange membrane varied and were named as BERL–30, 40, 50, 60, and 70. In addition, the performance and behaviour of the prepared anion exchange membrane were evaluated and compared with the commercial cation exchange membranes. The physico-chemical properties of anion exchange membrane were determined by measuring the membrane thickness, permselectivity, and concentration of ion exchange capacity, chemical stability, water content, and scanning electron microscope (SEM). It was found that the increase in the quantity of resin (%) would increase the capacity of ion exchange, percentage of permselectivity, and capacity concentration of ion exchange group. The experimental results showed that cation exchange membrane has the potential to be used in electrodialysis process.

<title>Active sensor system for automatic rendezvous and docking</title> (1997)

NASA's Marshall Space Flight Center has developed an active sensor system, the ideo guidance sensor (VGS), to provide near-range relative position and attitude data. The VGS will be part of an automatic rendezvous and docking system. The VGS determines the relative positions and attitudes between the active sensor and the passive target. It works by using laser diodes to illuminate the retro-reflectors in the target, a solid-state camera to detect the return from the target retro-reflectors, and a frame grabber and digital signal processor to convert the video information into relative positions and attitudes. The current sensor design is the result of several years of development and testing, and it is being built to fly as an experiment payload on the space shuttle. The VGS system is designed to operate with the target completely visible within a relative azimuth of +/- 10.5 degrees and a relative elevation of +/- 8 degrees. The system will acquire and track and target within that field-of-view anywhere from 1.0 meters to 110 meters range at any relative roll angle and relative pitch and yaw attitudes of up to +/- 10 degrees. The data is output from the sensor at 5 Hz, and the target and sensor software have been designed to permit two independent sensors to operate simultaneously for redundancy.
The Role of Linux in Reducing the Cost of Enterprise Computing (2001)

IDC’s recent study on Internet/intranet/extranet and collaborative workloads found significantly lower cost of ownership for Linux. To arrive at this important conclusion, we compared the total cost of ownership (TCO) of Linux on Intel architecture (IA) servers and RISC/Unix servers. Associated costs with Linux are not only dramatically lower for the hardware and software, as you might expect, but also comparable or lower for staffing — which you might not expect. With staffing typically the largest component of overall IT solution costs, this finding has important implications for IT planning. In summary, Linux provides a lower-cost platform for these workloads, especially in the first year of deployment. In the case of
Groundwater Budget of the ZaratÍ River Sub-Catchment (2022)

A groundwater balance is calculated considering inputs, outputs, and changes in storage, which occur in a specific volume of the aquifer in a given period of time. Therefore, as a general objective, it is proposed to study the behavior of groundwater in the middle and lower part of the sub-basin of the Zarati river to know its potential use as a possible source of water supply for the area of Penonome. Measurements of flows in the Zarati river and piezometric levels in monitoring wells were made. Information was obtained from the National Institute of Aqueducts and Sewers (IDAAN for its Spanish acronym) on the extraction flow of the active wells and the production flow of the Penonome potable water treatment plant. The results indicate that, the piezometric level in the monitoring wells decrease during the dry season, affecting the water supply. Also, that the groundwater flow descends from the middle part until reaching the lower sub-catchment, where most look towards the flow areas of the Zarati river. A volume of river-aquifer interaction of ΔV= -1.73 x m3 was obtained and it was determined that the aquifer feeds the river. It is recommended to design and implement a monitoring program in active wells that are within the Zarati river sub-catchment, which allows planning and managing efficiently in the long term, the quantity and quality of water for supply of the population.

Study of Flame Characteristics Using Electric Capacitance Tomography (2015)

With increasing awareness of energy savings and environmental protection in recently years, more emphasis on the monitoring of the intensity distribution in a flame and its stability have been raised in connection with the improvement of combustion efficiency and pollutant control. Albeit there are different opinions, it is generally recognized that Electrical Capacitance Tomography (ECT) measurement is directly related to the ionization of the flame, which in turn is closely related to the intensity of combustion. In this paper, a novel ECT sensor has been designed to withstand high temperatures and a series of experiments based on ECT system have successfully imaged diffusion flame of methane. Also, simulations on three dimensional sensitivity maps are generated to reconstruct images of 3D flame. Experiments and simulation results based on permittivity characteristics of a flame have successfully been used to image the flame, which in turn proves the assumptions raised in the study.
