Adverse Outcomes of Preeclampsia in Previous and Subsequent Pregnancies and the Risk of Recurrence

Objectives: We evaluated the fetal and maternal outcomes of pregnant women with preeclampsia who gave birth in our hospital; we also evaluated preeclampsia recurrence rates in these patients and their fetal and maternal outcomes in their subsequent pregnancy. Methods: In this retrospective cohort study, 126 patients whose medical records were accessed completely and who got pregnant again and gave birth in our hospital were analyzed. The primary aim was to show the recurrence rate of preeclampsia, while the secondary aim was to evaluate the maternal and fetal results of the first pregnancy in which preeclampsia developed and the subsequent pregnancy. Results: The incidence of preeclampsia was found to be 2.1% in our clinic. The first pregnancy in which preeclampsia developed; 111 (80.2%) pregnancies resulted in a live birth, 7 (5.6%) resulted in termination, and 8 (6.3%) resulted in stillbirth. Neonatal death occurred in 10 (7.9%) pregnancies. While 105 of the subsequent pregnancies resulted in a live birth, 10 (7.9%) resulted in abortion, 9 (7.1%) resulted in stillbirth, and 2 (1.6%) resulted in termination due to preeclampsia. Neonatal death developed in 3 (2.6%) pregnancies. In the subsequent pregnancy, preeclampsia developed in 70 (55.5%) patients and 39 (55.7%) of these had preeclampsia with severe features. Conclusion: The present study guides us on the risk factors related to preeclampsia and the rate of fetomaternal adverse outcomes and emphasizes the need for strict and regular antenatal follow-up in the subsequent pregnancies of women who have a history preeclampsia. Improvement of maternal and fetal morbidity and mortality in this way is the utmost goal.
Updating the U.S. Nationwide urban runoff quality data base

Urban stormwater quality data collected over the past 20 years for several large government-sponsored sampling programs in the United States were assembled and analyzed to develop new nationwide estimators and statistics for urban storm water quality. We believe that this is the first attempt to assemble and analyze these major storm water quality data sets for this purpose. In this paper, the first public report of our work to-date, we present the results of the data acquisition, data base assembly, quality assurance, computation of new stormwater event mean concentrations and associated statistics, and comparisons with the original U.S. Environmental Protection Agency9s Nationwide Urban Runoff Program (NURP) results. The differences between the pooled means and those estimated from our analysis of the NURP data range from a 79% lower estimate for Copper to a 36% higher estimate for Biochemical Oxygen Demand. It is concluded that the variations between the NURP results and those developed here from the pooling of the three national data bases are important and that future work may provide a basis for differentiating Event Mean Concentrations among urban land uses, geographic region and seasons.
Investigación formativa como estrategia pedagógica: caso de estudio ingeniería industrial de la I.U Pascual Bravo

The generation of a research culture and the integral formation of its professionals is a constant problem for the country’s higher education institutions; the separation between academia and society isolates universities from the context in which they interact, which is reflected in inflexible, non-relevant curricula and transmissionist teaching models that appeal to memory and the accumulation of data. Formative research emerges as a way to improve academic processes, aligning teaching and research, to foster the acquisition of research competencies, the generation of a research culture, and meaningful learning. This article presents the characterization of the formative research process in the industrial engineering program of the I.U Pascual Bravo, by means of a methodology with descriptive scope and mixed approach, divided in three phases; as a result an improvement in the formation and research processes of said program is expected.
A NOVEL SYNTHESIS METHOD OF SPARSE NONUNIFORM-AMPLITUDE CONCENTRIC RING ARRAYS FOR MICROWAVE POWER TRANSMISSION

A novel two-step synthesis method of sparse nonuniform-amplitude concentric ring arrays (SNACRAs) to maximize the beam collection efficiency (BCE ) for microwave power transmission (MPT) is proposed in this paper. In the first step, beetle antennae search (BAS) algorithm is used to optimize the radius of each ring of the SNACRA, to obtain the maximum BCE and the equivalent continuous excitation of each ring. In the second step, we find the least array element on each ring to discretize the continuous excitation on each ring by using the binary search (BS) algorithm directly under the restriction conditions and then find the excitation of each element. Through the above two steps of optimization, the optimal synthesized parameters of the SNACRA, including the maximum BCE, layout, excitation, and power pattern, can be obtained highly efficiently. Many representative numerical results under different ring numbers, apertures, and receiving areas are presented. Comparing these numerical results with those of other three arrays for MPT, it is proved that the SNACRA synthesized by the two-step method can get higher BCE with less elements and have a relatively simple feed network.
In situ FTIR studies of the effect of temperature on the adsorption and electrooxidation of CO at the Ru(0001) electrode surface

The adsorption and electrooxidation of CO at a Ru(0001) electrode in perchloric acid solution have been investigated as a function of temperature, potential and time using in situ FTIR spectroscopy. This builds upon and extends previous work on the same system carried out at room temperature. As was observed at room temperature, both linear (COL) and 3-fold-hollow (COH) binding CO adsorbates (bands at 2000−2045 cm-1 and 1768−1805 cm-1, respectively) were detected on the Ru(0001) electrode at 10 °C and 50 °C. However, the temperature of the Ru(0001) electrode had a significant effect upon the structure and behavior of the CO adlayer. At 10 °C, the in-situ FTIR data showed that the adsorbed CO species still remain in rather compact islands up to ca. 1100 mV vs Ag/AgCl as the CO oxidation reaction proceeds, with oxidation occurring only at the boundaries between the COad and active surface oxide/hydroxide domains. However, the IR data collected at 50 °C strongly suggest that the adsorbed CO species are prese.
Assessment of Factors Influencing the Development and Sustainability of Small Scale Foundry Enterprises in Nigeria: A Case Study of Lagos State

The study identifies types of small scale foundry enterprises operating in Lagos State and also assesses their development and sustainability. Data for the study were obtained from thirty (30) selected small scale foundry enterprises in Lagos and randomly sampled one hundred and fifty (150) of their consumers using questionnaire, focus group discussion (FGD) and Key informant Interview (KII). Data was analyzed using simple frequency method, statistical package of social sciences (SPSS) and qualitative analysis from the FGD and KII. The study revealed that the majority of the foundry enterprises jobbing foundries. The management strategy of the enterprises in terms of reliability (2.11), product and service quality (2.29), and business relationship with consumers (2.09) were satisfactory. Overall ranking shows erratic power supply, flooding market with imported goods, difficulty in obtaining raw materials, flooding the market with imported goods, low linkage between the knowledge institution and the industry, policy discontinuity as factors that highly affect the development of the foundry enterprises. It was concluded that most foundries in Lagos State in Nigeria are jobbing foundries and the remaining few are production foundries. Also, the rate of development of the foundry sector in Nigeria is very low. It was recommended that government policy continuity, provision of soft loan to foundry entrepreneurs, stable power supply, availability of raw materials at low cost, improving the linkage between the knowledge institution and the industry would enhance the development and sustainability of the small scale foundry enterprises in Nigeria.
Competitive Removal of Heavy Metal Ions by Starch-Graft-Acrylic Acid Copolymers

ABSTRACT Graft copolymerization of acrylic acid (AA) onto starch was carried out with ceric ammonium nitrate as initiator under nitrogen atmosphere. The structures of the synthesized graft copolymers were identified by Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). The grafting percentages (GP%) of starch-graft-acrylic acid (S-g-AA) copolymers were determined. Increasing the molar concentration of AA from 0.1 to 0.5 mol/L caused a significant increase in the GP%. The effect of GP% of S-g-AA copolymers on the competitive removal of Pb2+, Cu2+, Cd2+ ions from aqueous solution was investigated at pH 4.5. The concentrations of each ion in aqueous solution were equal to each other, which were kept constant at 4 mmol/L. Metal ion removal capacities were determined by atomic absorption spectrophotometer (AAS). Metal ion removal capacities of S-g-AA copolymers rose with the increase in GP% of the copolymers and the order of the removal of heavy metal ions was Pb2+ > Cu2+ > Cd2+.
Weakened Patient Loyalty Model at Beauty Clinics: Based on Variety Seeking Behavior, Dissatisfaction, Negative WOM and Brand Switching

The purpose of this study was to design the Weakened Loyalty model through Variety Seeking Behavior, Dissatisfaction, Negative WOM and Brand Switching. The sample in this study was a patient of a beauty clinic who did treatment for one year or more and had moved from another clinic. The sample used was 173 respondents. Data analysis using Structural Equation Modeling with PLS approach. The data meets convergent validity and composite reliability. The results of the analysis prove that negative WOM, variety seeking behavior and dissatisfaction are factors that have the potential to weaken loyalty, because these three variables have a significant direct effect on brand switching. However, it does not directly affect patients to really weaken loyalty. Dissatisfaction can mediate relationship between Negative WOM and Brand Switching.
Electrochromic properties of intercrossing nickel oxide nanoflakes synthesized by electrochemically anodic deposition

Nanostructured nickel oxide film is synthesized directly onto a transparent and conducting indium tin oxide coated glass substrate by electrochemically anodic deposition from an aqueous solution. The deposited nickel oxide film has an intercrossing nanoflake and highly porous morphology. X-ray diffraction peaks of the film resemble closely to the cubic NiO structure. The deposited film oxidized/reduced electrochemically at 0.36 and 0.25V versus a saturated Ag∕AgCl electrode, respectively, which corresponds to the reversible changes in coloration and bleaching. The difference in optical response (transmittance) ΔT at wavelength of 550nm between the colored state and bleached state can reach as high as 80%.
Analgesia for Pediatric Arteriovenous Fistula Cannulation in Hemodialytic Patients: A Comparison of Lidocaine Gel, Lidocaine Spray, and Needle Plate

Background: Children undergoing hemodialysis (HD) via arteriovenous fistula (AVF) experience approximately 300 painful punctures per year which may lead to non-compliance with HD. This study was conducted to show the effect of local anesthetics on pain perception in AVF cannulation. Methods: This randomized clinical trial included 20 children under HD via AVF in Sheikh Children's Hospital Hemodialysis Center in February 2014. The first intervention was conducted as the baseline pain assessment (control), then every patient randomly received all three other interventions: Lidocaine gel, lidocaine spray, and needle plate, before venipuncture. Pain perception was expressed and recorded by patients using the visual analogue scale (VAS). VAS scores were compared, and a P value of <0.05 was considered significant. Results: The VAS mean in lidocaine spray state, lidocaine gel state, and needle plate state was respectively 47.87, 51.31, and 49.43, which were significantly less than the control state with the VAS mean of 60.06 (lidocaine spray vs. control P value = 0.001, lidocaine gel vs. control P value = 0.001, and needle plate vs. control P value = 0.003). Conclusion: Our study showed that the use of needle plate, lidocaine spray, and lidocaine gel are all equally effective ways in controlling the degree of pain in AVF needling in children undergoing HD.
A Comparison of School Climate Ratings in Urban Alternative and Traditional High Schools

We investigated whether there are significant differences in ratings of school climate from the perspectives of students, parents, and school staff across four types of urban secondary schools. Data originated from a school climate survey administered in a large urban Midwestern school district to students attending traditional and alternative high schools. We coded all high schools in the sample district into four school types, including traditional, innovative, behavior-focused, and academic remediation-focused. We analyzed data using linear mixed-model regression. Results showed statistically significant differences in specific dimensions of school climate across stakeholder groups and the four school types. Analysis of student data indicated ratings of Learning-Focused Environment are significantly lower in traditional schools. Analysis of parent data indicated ratings of Academic Preparation and Community Engagement are significantly higher in innovative alternative schools. Analysis of staff data indicated ratings of Staff Engagement are significantly lower in traditional schools. These findings suggest discrepant educational opportunities related to specific dimensions of climate according to school type.
System Advantages of Using Large-Scale Aperiodic Array Topologies in Future mm-Wave 5G/6G Base Stations: An Interdisciplinary Look

The encouraging potential of employing large-scale aperiodic base station arrays in addressing the radiation pattern and thermal requirements of the next generation communication systems is demonstrated. Sample 256-element layout-optimized multibeam arrays are presented as a futuristic view. The system benefits (in terms of the statistical quality-of-service, energy efficiency, thermal management, and processing burden) of the proposed arrays, as well as their performance versus design complexity tradeoffs, are explained through interdisciplinary simulations. The key advantage of the proposed antennas over the currently proposed 64-element periodic arrays is identified as the increased gain with much lower side lobes, which yields much less power and less heat per element with more surface for cooling, and allows robust/computationally efficient precoding.
Combinatorial Enzyme Approach for Production and Screening of Libraries of Feruloyl Oligosaccharides

Combinatorial chemistry involves the chemical or biological synthesis of diverse variation of the structures of a target molecule and the library is then screened for variants of desirable target properties. The approach has been a focus of research activity in drug discovery and biotechnology. This report is to demonstrate the application of enzyme technology using the concept of combinatorial chemistry as a novel approach for the bioconversion of plant fibers. Wheat insoluble fiber was subjected to combinatorial enzyme digestion to create structural variants of feruloyl oligosaccharides (FOS). Fractionation and screening resulted in the isolation of a fraction of bioactive FOS species showing antimicrobial activity. These results demonstrate the feasibil-ity and usefulness of the combinatorial enzyme technique in the transforma-tion of plant biomass to value-added products.
Does mining fuel bubbles? An experimental study on cryptocurrency markets

The massive price bubbles of decentralized cryptocurrencies, such as Bitcoin, have created a puzzle for economists. How can a non-revenue-generating asset exhibit such extreme price dynamics, forming multiple episodes of bubbles and crashes since its creation? The answer is not straightforward, since cryptocurrencies differ in several important aspects from other conventional assets. In this paper, we investigate how key features associated with the Proof-of-Work consensus mechanism affect pricing. In a controlled laboratory experiment, we observe that the formation of price bubbles can be causally attributed to mining. Moreover, bubbles are more pronounced if the mining capacity is centralized to a small group of individuals. Analysis of the order book data reveals that miners seem to play a crucial role in bubble formation. The results demonstrate that high price volatility is an inherent feature of cryptocurrencies based on a mining protocol, which seriously limits any prospects for such assets truly becoming a medium of exchange.
Effects of beech and ash on small‐scale variation of soil acidity and nutrient stocks in a mixed deciduous forest

Treesinteractinacomplexmannerwithsoils:theyrecycleandredistributenutrientsviamanyecological pathways. Nutrient distribution via leaf litter is assumed to be of major importance. Beech is commonly known to havelower nutrient concentrationsinits litter thanother hardwoodtreespecies occurring in Central Europe. We examined the influences of distribution of beech (Fagus sylvatica L.), ash (Fraxinus excelsior L.), lime (Tilia cordata Mill. and T. platyphyllos Scop.), maple (Acerspp.L.),andclaycontentonsmall-scalevariabilityofpHandexchangeableCaandMgstocks in the mineral soil and of organic-C stocks in the forest floor in a near-natural, mature mixed deciduous forest in Central Germany. The soil is a Luvisol developed in loess over limestone. We found a positive effect of the proportion of beech on the organic-C stocks in the forest floor and a negative effect on soil pH and exchangeable Ca and Mg in the upper mineral soil (0 to 10cm). The proportion of ash had a similar effect in the opposite direction, the other species did not show any such effect. The ecological impact of beech and ash on soil properties at a sample point was explained best by their respective proportion within a radius of 9 to 11 m. The proportion of the species based on tree volume within this radius was the best proxy to explain species effects. The clay content had a significant positive influence on soil pH and exchangeable Ca and Mg with similar effect sizes. Our results indicate that beech, in comparison to other co-occurring deciduous tree species, mainly ash, increased acidification at our site. This effect occurred on a small spatial scale and was probably driven by species-related differences in nutrient cycling via leaf litter. The distribution of beech and ash resulted not only in aboveground diversity of stand structures but also induced a distinct belowground diversity of the soil habitat.
Intangible Motives in Creating Health Workers Satisfaction

The aim of the paper is to determine how much intangible motives are involved in nursing satisfaction. The research population consisted of nurses with secondary and university degrees in the field of multiple health centers in the central part of Croatia. Random selection based on data collected from different nursing associations was used. The survey was conducted in 2019. The dependent variable is the nurses' satisfaction. There are five independent variables: position in the organization, independence in work, communication, work organization and working hours, education and career development. Among the variables included, the most significant correlation with nurses' satisfaction was their existing position in the organization of the health care institution, which is followed by education and career development. Communication is the lowest-ranked intangible motive correlated with respondent satisfaction. The lessons learned are believed to have value and carry an initial message. The intangible motives for creating nursing satisfaction identified in this research can realistically be an incentive and a roadmap for public health managers in a context where the transition economy is unable to respond to the pace of growth in health needs and health spending through an existing approach where material motivations have dominated in creating satisfaction for healthcare professionals.
Acúmulo de nitrogênio e de fósforo em plantas de milho afetadas pelo suprimento parcial de fósforo às raízes

Two split root trials were carried out in nutrient solution to evaluate nitrogen accumulation as a function of phosphorus supply applied in partial contact to maize roots. After a seven day growth period in complete nutrient solution, maize seedlings were transplanted to joint pots containing 1.6 L of nutrient solution. Roots were equally shared between the pots. In the first trial, two phosphorus levels (0.02 mmol L-1 and 0.1 mmol L-1) and phosphorus and nitrogen placement were evaluated. In the second trial, two nitrogen sources (nitrate and ammonium) and the same nitrogen and phosphorus placement design adopted in the first trial were assessed. There was a greater phosphorus accumulation in the shoots as a consequence of phosphorus supplied to the whole root system as compared to just half of it. Phosphorus supplied to part of the root system did not properly provide this nutrient to the other part, a fact which raises the possibility of inner phosphorus cycling problems in maize plants. These results were verified for nitrogen as well. When jointly supplied to the whole root system, nitrogen and phosphorus caused greater accumulation of nitrogen in the shoots.
“We Are Nature”: Exploring Nature Conceptualizations and Connections through Children's Photography

Abstract:In an increasingly technological age, photography provides a medium for exploring and engaging with nature. This study examines children's conceptualizations and avenues of engagement using children's nature photographs and comments as documented through the school-based Focus on Nature program in Ontario, Canada. We find that children can view nature literally (i.e., as consisting of living, non-living, dead, or human-made things), symbolically (i.e., representing other things or prior experiences), and as a dynamic and static entity. Avenues of connection to nature through photography extend the cognitive-behavioral-sensory-affective model of experience via imagination to include artistic connections such as symbolism, photo-editing, and perspective-taking.
