Objective: Characterize the hypertensive patients admitted in the Internal Medicine Ward, and analyze the blood pressure control and therapeutic strategies adopted. Design and method: Observational/retrospective study of the hypertensive population admitted in an Internal Medicine ward during a month, focusing on demographic data, type of Hypertension, cardiovascular risk factors, diagnosis, blood pressure and therapeutic changes at discharge Results: In a total universe of 89 patients admitted during a month in the analyzed ward, there were 68 with previous diagnosis of hypertension. The average age was 76,7 and 58,8% were woman; most (52,9%) with systolic hypertension. Diabetes and Dyslipidemia were the most frequent risk factors, but there was a significant omission of data regarding other cardiovascular risk factors and particularly about presence of target-organ damage. Stroke was a previous event in 41,1%. In average, patients were treated with 2 antihypertensive drugs (maximum 5), mostly diuretics (54,4%) and ACE inhibitors (38,2%); 10 patients had no medication despite the diagnosis. Most patients (51,5%) were admitted for cardiovascular disease – 19 had acute stroke. At admission, 30 patients had normal blood pressure and 4 were hypotensive; 50% had isolated systolic hypertension. During admission time, 73,5% had controlled blood pressure in more than 50% of evaluations. The therapeutic regime was optimized during the admission in 41 patients (60,3%): increased dose in 24 cases, and association of a new drug class in 28 patients. At the discharge date 31 patients had controlled blood pressure. The ambulatory therapeutic was changed in 32 patients: calcium antagonists prescription rise, as for beta-blocker, and there was a decrease in diuretics and ARABs. Conclusions: The prevalence of Hypertension in Portugal has been recently estimated in 42.2%. During a hospital admission, it is associated with significant morbidity and mortality, and is easily decompensated by the acute disease. Hospital admission is a key moment for the cardiovascular risk stratification and therapeutic optimization, as patient are under a more controlled surveillance, despite the acute disease. Clinicians should pay more attention to blood pressure control during admissions, and take the opportunity to adjust the therapeutic regime.
Determination of phthalate esters in edible vegetable oils by gas chromatography tandem mass spectrometry (2013)

A simultaneous and fast determination of 16 phthalate esters(PAEs) in edible vegetable oils was developed.After solvent extraction,the PAEs in the oil sample were further cleanup by solid phase extraction.After concentration,the extract was directly injected into gas chromatography tandem mass spectrometry(GC-MS/MS).Method quantification limits of 16 PAEs were 0.004~0.01 mg/kg.Quantitative recoveries were 67.5%~117% by analysis of spiked vegetable oil in low,middle and higher levels.The relative standard deviations were less than 15%(n=6).The method could potentially overcome the interference from large amounts of lipids and pigment,and the whole analysis could be completed within 1 h.It showed to be a rapid and reliable alternative for determination and confirmation of PAEs in the routine analysis.
Waning Tdap Effectiveness in Adolescents (2016)

Routine Tdap did not prevent pertussis outbreaks. Among adolescents who have only received DTaP vaccines in childhood, Tdap provided moderate protection against pertussis during the first year and then waned rapidly so that litle protection remained 2-3 years after vaccination..

Vertical stratification in PCDTBT1:PC<sub>71</sub>BM bulk heterojunction solar cells were investigated by neutron reflectivity and found to have profound impacts on device performance.
Decision -making from on -farm experiments: Spatial analysis of precision agriculture data (2006)

The goal of this research was to adapt spatial regression methods to on-farm trials in a farm management context. Three essays address this issue. The first essay tested different experimental designs and statistical analysis methods with site-specific data under a range of spatial autocorrelation levels using Monte Carlo simulation techniques. Simulations indicated that data usable for farm management decision making could be gathered from limited replication experimental designs if that data were analyzed with the appropriate spatial statistical model. The second essay adapted spatial analysis methods to a series of on-farm trials conducted by farmers. Farmers conducted on-farm trials using candidate experimental designs identified from the first essay. Available data were assimilated into a spatial dataset, analyzed with traditional and appropriate spatial statistical methods, and results provided to the farmers. Two datasets were created for each field study, one using the yield monitor data exported from farm mapping software with the default parameter settings, and another using yield monitor data subjected to a conscious removal of erroneously measured observations and adjustment for location. Each dataset was evaluated using one aspatial and two spatial analysis techniques to determine if farm management recommendations based on differing levels of yield data quality and statistical method differed from one another. Results indicated that differences in farm management recommendations existed between yield monitor data quality levels unless the most advanced specification of the spatial correlation structure was used in the spatial analysis. The third essay evaluated farmer response to spatial analysis including their perceptions of on-farm trials for farm management decision making and expectations for future spatial analysis services. Case study methods were used to gather evidence and make comparisons across cases. Case study results indicated that farmers receiving spatial analysis reports had more confidence in their farm management decisions based upon on-farm trial data than farmers not receiving spatial analysis reports. Not only did farmers make decisions quicker, but they made more decisions than they would have without spatial analysis. Case study farmers opted to use large treatment block split-field designs, while the control group chose the numerous replications associated with split-planter strip-trial designs.
Macrophage Polarization in Obesity and Type 2 Diabetes: Weighing Down Our Understanding of Macrophage Function? (2014)

Obesity and type 2 diabetes are now recognized as chronic pro-inflammatory diseases. In the last decade, the role of the macrophage in particular has become increasingly implicated in their pathogenesis. Abundant literature now establishes that monocytes get recruited to peripheral tissues (i.e., pancreas, liver, and adipose tissue) to become resident macrophages and contribute to local inflammation, development of insulin resistance, or even pancreatic dysfunction. Furthermore, an accumulation of evidence has established an important role for macrophage polarization in the development of metabolic diseases. The general view in obesity is that there is an imbalance in the ratio of M1/M2 macrophages, with M1 "pro-inflammatory" macrophages being enhanced compared with M2 "anti-inflammatory" macrophages being down-regulated, leading to chronic inflammation and the propagation of metabolic dysfunction. However, there is emerging evidence revealing a more complex scenario with the spectrum of macrophage states exceeding well beyond the M1/M2 binary classification and confused further by human and animal models exhibiting different macrophage profiles. In this review, we will discuss the recent findings regarding macrophage polarization in obesity and type 2 diabetes.
Structural and multiferroic properties of BiFeO3 thin films at room temperature (2004)

BiFeO 3 thin films have been prepared on Pt∕TiO2∕SiO2∕Si substrates under various oxygen pressures of 0.15–0.005Torr at a temperature of 450°C by pulsed-laser deposition. The effects of deposition pressure on their crystal structure and multiferroic properties have been investigated at room temperature. X-ray diffraction analysis (θ-2θ scans and 2-dimensional scans) shows that the BiFeO3 thin films consist of perovskite single phase with tetragonal crystal structure and space group P4mm. The c-axis lattice constant decreases (4.062–4.006Å) and c∕a ratio of the films decreases from 1.032 to 1.014 with a decrease in the oxygen pressure. The surface roughness and grain size of the films depend dramatically on oxygen pressures. The dielectric constant of the films decreases with decreasing oxygen pressure. The film deposited at 0.05Torr shows a stable current density and well-saturated hysteresis loop with twice the remanent polarization (2Pr) of 136μC∕cm2 and coercive field (2Ec) of 109kV∕cm. The BiFeO3 thin films also show the saturated weak ferromagnetic hysteresis loops with a small remanent magnetization.
Development of ultra‐high sensitivity bioluminescent enzyme immunoassay for prostate‐specific antigen (PSA) using firefly luciferase (2001)

A bioluminescent enzyme immunoassay (BLEIA) for prostate-specific antigen (PSA) using biotinylated firefly luciferase-labelled antibody was developed. PSA is an important marker for the diagnosis and management of prostate cancer. Our BLEIA for PSA, based on the two-step sandwich method, had ultra-high sensitivity and a very wide measurable range. The detection limit (mean of nine replicates of the zero standard +2 SD) for PSA was 0.25 pg/mL and the measurable range for PSA was 0.25 pg/mL–100 ng/mL. Generally, PSA in the serum exists on two forms, called free PSA (f-PSA) and complex PSA (c-PSA), which is formed with α-antichymotripsin. Thus, the response of the PSA assay to these two forms has to be equimolar in the construction of the assay system. Our BLEIA for PSA also had an equimolar response to them.

Ground-penetrating radar theory and application of thin-bed offset-dependent reflectivity (2006)

Abstract Offset-dependent reflectivity or amplitude-variation-with-offset (AVO) analysis of ground-penetrating radar (GPR) data may improve the resolution of subsurface dielectric permittivity estimates. A horizontally stratified medium has a limiting layer thickness below which thin-bed AVO analysis is necessary. For a typical GPR signal, this limit is approximately 0.75 of the characteristic wavelength of the signal. Our approach to modeling the GPR thin-bed response is a broadband, frequency-dependent computation that utilizes an analytical solution to the three-interface reflectivity and is easy to implement for either transverse electric (TE) or transverse magnetic (TM) polarizations. The AVO curves for TE and TM modes differ significantly. In some cases, constraining the interpretation using both TE and TM data is critical. In two field examples taken from contaminated-site characterization data, we find quantitative thin-bed modeling agrees with the GPR field data and available characterization data.
Generation of tunable narrow-band THz radiation from large aperture photoconducting antennas (1994)

We report a novel technique for the generation of tunable narrow-band submillimeter wave electromagnetic radiation in free space. This is accomplished by mixing two linearly chirped optical pulses with a variable time delay on a biased large aperture GaAs photoconducting antenna. The center frequency of the THz radiation varies linearly with the delay between the two chirped pulses from dc to ∼1 THz.
Influence of vesicular storage and monoamine oxidase activity on [11C]phenylephrine kinetics: studies in isolated rat heart. (1999)

These studies indicate that PHEN kinetics are sensitive to neuronal MAO activity. Under normal conditions, efficient vesicular storage of PHEN serves to protect the tracer from rapid metabolism by neuronal MAO. However, it is likely that leakage of PHEN from the storage vesicles and subsequent metabolism by MAO lead to an appreciable clearance of radioactivity from the heart.
Improved Dehydrogenation Properties of Ti-Doped LiAlH<sub>4</sub>: Role of Ti Precursors (2012)

The dehydrogenation properties of LiAlH4 doped with different Ti precursors (Ti, TiO2, and TiCl3) via ball milling are investigated. The results not only show significant decreases in the decomposition temperatures (T-dec) and activation energies (E-A) of the first two dehydrogenation reaction steps of LiAlH4 by doping with TiO2 or TiCl3, but also reveal how each Ti precursor affects the dehydrogenation process. Although doping LiAlH4 with TiCl3 induced the largest decrease in T-dec and E-A, TiO2-doped LiAlH4 produced a decrease in T-dec and E-A that is quite close to the TiCl3-doped sample as well as superior short-term stability, suggesting that doping with TiO2 has certain advantages over doping with TiCl3. Further, the underlying mechanisms associated with the Ti precursors during the dehydrogenation reaction of LiAlH4 have been studied using quasi in situ X-ray photoelectron spectroscopy. The results reveal that the Ti4+ and Ti3+ reduction processes and the segregation of Li cations to the surface of LiAlH4 during ball milling play critical roles in the improved dehydrogenation properties observed.
Hubungan Antara Dukungan Sosial Orang Tua dengan Motivasi Belajar Siswa SDK St. Ursula Ende (2021)

This study aims to determine the relationship between parental social support and learning motivation of elementary school students. This research was correlational research with a quantitative approach. The population in this study were students of SDK St. Ursula, amounting to 435 people and the sample were 80 students in 5 and 6 grades with a purposive sampling technique. The data collection method used a questionnaire with the measuring instrument that consisted of the scale of parents social support and the scale of student learning motivation. Data analysis was carried out by using product moment correlation which was calculated using SPSS version 26. The results showed the r value of 0.624, which means that there is a significant positive relationship between parents social support and student learning motivation at SDK St. Ursula where the higher the parents social support, the higher the learning motivation of elementary school students, and conversely the lower the parents social support, the lower the learning motivation of elementary school students.
A novel InP/InAlGaAs negative-differential-resistance heterojunction bipolar transistor (NDR-HBT) with interesting topee-shaped current-voltage characteristics (1999)

A new and interesting negative-differential-resistance heterojunction bipolar transistor (NDR-HBT) based on the InP/InAlGaAs material system is fabricated successfully and demonstrated. Due to the employment of narrow base and /spl delta/-doped sheet at the emitter-base (E-B) heterojunction, the significant and interesting topee-shaped current-voltage (I-V) characteristics are observed in the low current regime. A peak-to-valley current ratio (PVCR) up to 11 in the NDR loci is found. In the higher current regimes, on the other hand, NDR phenomena disappear and the device acts as a normal bipolar transistor. These interesting properties are believed to be attributed mainly to the modulation of potential spike resulting from the specified device structure.
Hybridization capture of microsatellites directly from genomic DNA (1997)

A rapid approach for isolation of microsatellites and other tandem repeated sequences in described. The method is based on hybridization capture of repetitive elements from digested genomic DNA using biotinylated oligonucleotide probes in solution and subsequent attachment to magnetic beads coated with streptavidin. Captured fragments are amplified by adapter polymerase chain reaction (PCR) and the PCR products enriched for microsatellites cloned directly into a T-vector for sequencing. The results presented here show that this approach is highly effective, allowing di- and trinucleotide repeats to be isolated and sequenced directly from fish and mammalian genomic DNA within four to five days. Assuming a density and relative abundance of repeats with AC/GT motifs corresponding to that found in the human genome, the protocol presented gives at least a 35-fold enrichment of AC/GT microsatellites using an (AC)10 oligo probe. In addition, four out of five sequences captured by a (CAG)9 oligo probe contained one or several CAG repeat arrays. The efficiency of this direct approach suggests that it can be used for extracting other types of tandem and interspersed repeated sequences (including transposons, rRNA and tRNA genes and proviruses) from vertebrate genomes.
Li<sup>+</sup> interstitials as the charge carriers in superionic lithium-rich anti-perovskites (2015)

Here, we report that in lithium-rich anti-perovskites (LiRAPs) with lithium halide deficiency, Li<sup>+</sup> interstitials outnumber vacancies by 2–3 orders of magnitude, so that interstitials might be the actual charge carriers responsible for superionic conduction, as opposed to what has been assumed so far.
A super high speed PM motor drive system by a quasi-current source inverter (1994)

This paper describes a surface mounted PM motor with the ratings of 5 kW and 150000 RPM for super high speed drive applications such as a machine tool. A much larger air gap, compared with that of the existing PM motors, is utilized to reduce the slot ripples and hence the resultant eddy current loss in the metallic sleeve that retains the permanent magnets, otherwise this loss would be objectionable at such high speeds. The motor is supplied from a quasi-current source inverter with the DC current controlled by a chopper and operated at a near unity power factor by the use of a simple position sensor-less control, to improve the motor efficiency. The analytic results are presented to show the slot ripple reducing effect of increasing the air gap length. To investigate the losses of the sleeve, several motors with different sleeves were manufactured and tested. Typical experimental results on these prototypes are given, which show that motor efficiency of higher than 90% can be realized at the rated torque over a wide speed range.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Practicing What is Preached: 80-20 Rules for Strategic IV&#x00026;V Assessment (2007)

The notion of using an 80-20 rule to drive decision making has been around for decades. Yet the details of how to turn this general principle into something operational have remained elusive. In reality, no-one has created concrete rules for how to realize an 80-20 rule as a business strategy. In this paper we show how to use empirical project data to create provably optimal strategic risk reduction strategies. While the domain of our example is in IV&V, this technique is usable in general, and may be applied to any software engineering activity where there are multiple goals to be met, multiple techniques that can partially meet those goals, and empirical data of the effectiveness of each technique in isolation. We illustrate this technique using real data from an aerospace ground tracking system.
Surviving the Breakup: The DNA Damage Checkpoint (2006)

In response to even a single chromosomal double-strand DNA break, cells enact the DNA damage checkpoint. This checkpoint triggers cell cycle arrest, providing time for the cell to repair damaged chromosomes before entering mitosis. This mechanism helps prevent the segregation of damaged or mutated chromosomes and thus promotes genomic stability. Recent work has elucidated the molecular mechanisms underlying several critical steps in checkpoint activation, notably the recruitment of the upstream checkpoint kinases of the ATM and ATR families to different damaged DNA structures and the molecular events through which these kinases activate their effectors. Chromatin modification has emerged as one important component of checkpoint activation and maintenance. Following DNA repair, the checkpoint pathway is inactivated in a process termed recovery. A related but genetically distinct process, adaptation, controls cell cycle re-entry in the face of unrepairable damage.
Investigating the Role of Dye Dipole on Open Circuit Voltage in Solid-State Dye-Sensitized Solar Cells (2011)

To eliminate the possibility of perturbation caused by a liquid electrolyte and predict the role played by the nature of dipole of sensitizers with respect to the observed open circuit voltage ( V oc ) in dye-sensitized solar cells (DSSCs) more precisely, solid-state DSSCs were fabricated using different sensitizing dyes. Results obtained by surface potential measurement indicate that increasing the alkyl chain length in symmetrical squaraine dyes leads to a relatively positive shift in surface potential. The use of dyes exhibiting higher surface potentials leads to the observation of increased V oc , which has been explained by the dye dipole formation at the TiO 2 /hole transporting layer interface leading to an upward shift of the TiO 2 conduction band. It is thus possible to obtain a high V oc in DSSCs by designing new dyes either having long alkyl chains or a molecular structure having a higher dipole moment exhibiting a relatively positive shift in surface potential.
Cortisol's effects on human mental functioning. (1982)

Popularization of the dexamethasone suppression test has focused attention on the relation between cortisol metabolism and mood and behavior. This article considers the biochemistry, physiology, and pharmacology of cortisol and cortisol-like substances. In addition, the effects of external stresses on cortisol metabolism and circadian rhythmicity of secretory patterns are reviewed. Finally, managing exogenous cortisol excess in a clinical setting is discussed.
Research in vehicle information systems at General Motors (2003)

An overview is provided of the authors' past and current research on vehicle-borne location and map display systems. Possible future research directions in the broader area of vehicle information systems are also outlined. Current research is directed toward the presentation of information to a driver to help in following a selected route to a desired destination. It is noted that the development of viable new products in the area of vehicle information systems will require thorough understanding of human needs, capabilities, and limitations, as well as mastery of the underlying technology. The basic goal of the current program is to optimize the human-machine interface of a route guidance system by developing effective displays and controls, thereby maximizing utility and ease of use while minimizing potential driver distraction.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
High efficiency thin-film GaAs-based MSM photodetectors (1996)

To increase the sensitivity of high speed GaAs based metal-semiconductor-metal (MSM) photodetectors, thin film inverted MSMs (fingers on the bottom) have been fabricated and compared to bulk MSMs. The inverted MSMs exhibit a record 95% external quantum efficiency, a bandwidth of 5.9 GHz, and <5 nA dark current at 10 V bias.
Facile Method To Synthesize Mesoporous Multimetal Oxides (ATiO<sub>3</sub>, A = Sr, Ba) with Large Specific Surface Areas and Crystalline Pore walls (2010)

A strategy to synthesize mesoporous SrTiO3 and BaTiO3 powders by using in situ inorganic carbonate pore-makers was reported. The carbonate pore-makers are stable at high temperature and can support the target mesostructures. The other important role of carbonate is to inhibit the growth of crystals, thus improving the porosity of the desired mesostructures.
