Circularly polarized low-profile antenna for radiating parallel to ground plane for RFID reader applications

This paper presents a low-profile printed antenna with double U-shaped arms radiating circular polarization for the UHF RFID readers. The proposed antenna consists of double U-shaped strip structures and a capacitive feeding line to generate circular polarization. A part of the U-shaped arms is bent by 90° to direct the main beam parallel to the ground plane. From the results, 10 dB <path id="x53" d="M409 504l-29 -5q-16 60 -44.5 96t-86.5 36q-54 0 -82.5 -32t-28.5 -77q0 -51 30.5 -82.5t96. 5 -65.5l35.5 -18t33 -19.5t33. 5 -23.5l27 -25.5t24. 5 -32t13.5 -36.5t6 -45q0 -80 -62 -134.5t-160 -54.5q-47 0 -98 15q-22 7 -50 21q-8 23 -27 155l30 7q7 -27 18 -52 t30 -51.5t49 -42.5t67 -16q56 0 88 32.5t32 87.5q0 51 -31.5 82t-98.5 67q-80 44 -110 73q-55 53 -55 124q0 75 56 126.5t150 51.5q53 0 126 -23z" /> and 3 dB axial ratio of the antenna cover a typical UHF RFID band from 920 MHz to 925 MHz.

Some Notes on the Surrogate Production Function

If factor intensities are the same in all sectors at all factor-price ratios the technology can be represented by what Samuelson [3] called the Surrogate Production Function, a smooth continuous non-decreasing correspondence between the value of output per man, y, and the value of capital per man, j, reckoned at competitively determined prices. In that same paper he acknowledged Garegnani's claim that the condition of equal factor intensities was the only one under which the surrogate production function retained its validity. At Samuelson's suggestion Garegnani published his results [2], basing his proof on the one capital good case and generalizing. That might have been the end of the story except for the fact that this is not the only sufficient condition for a well defined surrogate production function. It is argued here that in certain cases multi-sector models may have surrogate representations even when different factor intensities are allowed. Furthermore, when there is only one capital good, the proof does not depend on the requirement of balanced growth or stationarity. First, some preliminary lemmas are proved. Then it is shown that when there is a single capital good and one type of homogeneous labour, both of which are supplied inelastically, the two sector Uzawa [7] model has a surrogate representation whenever the consumption goods industry is the more capital intensive. Finally, some of the problems that arise when capital is heterogeneous are discussed. Let F be a concave homogeneous neoclassical production function3 which satisfies the Inada conditions.

Birth Defects in Offspring of Female Veterinarians

Objectives: To investigate the risk of birth defects in offspring of female veterinarians exposed to occupational hazards such as radiation, anesthetic gases, and pesticides in veterinary practice. Methods: The Health Risks of Australian Veterinarians project was conducted as a questionnaire-based survey of all graduates from Australian veterinary schools during the 40-year period 1960–2000. Results: In a multiple logistic regression controlling for the potential confounders, the study showed an increased risk of birth defects in offspring of female veterinarians after occupational exposure to high dose of radiation (taking more than 10 x-ray films per week, odds ratio: 5.73 95% CI: 1.27 to 25.80) and an increase risk of birth defects after occupational exposure to pesticides at least once per week (odds ratio: 2.39 95% CI: 0.99 to 5.77) in veterinarians exclusively working in small animal practice. Conclusion: Female veterinarians should be informed of the possible reproductive effects of occupational exposures to radiation and pesticides.
Results of the Kentucky high school football knee injury survey.

The study attempted to: 1) determine knee injury and reinjury incidence of Kentucky high school football players; 2) relate results to initial care provider, treatment following initial physician exam, time lost from injury, injury type, player position, and team size; and 3) assess coaches opinions and practices about lateral prophylactic knee brace (LPKB) usage and effectiveness. A post season, mail-in coaches' survey (50.2% return, 101/201) collected these data. Returned surveys represented 4690 players with average team size (x +/- SD) of 43 +/- 13. Two hundred fifty seven reported knee injuries yielded . 055 knee injuries/player with . 04 knee injuries/player being "new" and . 015 knee injuries/player recurring (27% of reported knee injuries) during the season. Games accounted for 56.4% (56/101) of reported knee injuries. Coaches generally believed that LPKB usage prevented knee injuries (56.4%, 56/101) and allowed LPKB usage (92.1%, 93/101), however only 8.3% (8/101) required their wear (interior linemen 50%, linebackers 25%, entire team (25%). Interior linemen had the greatest number of knee injuries, followed by offensive backs and linebackers. Most knee injuries (81%, 208/257) were out 3-6 weeks or less, 64% (164/257) involved sprains or contusions, 38% (97/257) were treated surgically (alone or with rehabilitation) and 36% (92/257) were treated solely with rehabilitation. Total knee injury and reinjury incidence were under-estimated compared to existing reports. Improved injury recording methods, and post-symposia coaches evaluation are recommended.
Impact of expiratory trigger setting on delayed cycling and inspiratory muscle workload.

RATIONALE During pressure-support ventilation, the ventilator cycles into expiration when inspiratory flow decreases to a given percentage of peak inspiratory flow ("expiratory trigger"). In obstructive disease, the slower rise and decrease of inspiratory flow entails delayed cycling, an increase in intrinsic positive end-expiratory pressure, and nontriggering breaths. OBJECTIVES We hypothesized that setting expiratory trigger at a higher than usual percentage of peak inspiratory flow would attenuate the adverse effects of delayed cycling. METHODS Ten intubated patients with obstructive disease undergoing pressure support were studied at expiratory trigger settings of 10, 25, 50, and 70% of peak inspiratory flow. MEASUREMENTS Continuous recording of diaphragmatic EMG activity with surface electrodes, and esophageal and gastric pressures with a dual-balloon nasogastric tube. MAIN RESULTS Compared with expiratory trigger 10, expiratory trigger 70 reduced the magnitude of delayed cycling (0.25 +/- 0.18 vs. 1.26 +/- 0.72 s, p < 0.05), intrinsic positive end-expiratory pressure (4.8 +/- 1.9 vs. 6.5 +/- 2.2 cm H(2)O, p < 0.05), nontriggering breaths (2 +/- 3 vs. 9 +/- 5 breaths/min, p < 0.05), and triggering pressure-time product (0.9 +/- 0.8 vs. 2.1 +/- 0.7 cm H2O . s, p < 0.05). CONCLUSIONS Setting expiratory trigger at a higher percentage of peak inspiratory flow in patients with obstructive disease during pressure support improves patient-ventilator synchrony and reduces inspiratory muscle effort. Further studies should explore whether these effects can influence patient outcome.

Pseudoseizures

EPILEPSY is not easily defined.1 Attempts to define hysterical epilepsy are only occasionally encountered.2-6 Edelston7 states that “It is scarcely possible to define where hysteria ends and epilepsy begins. ” Lennox, in his remarkable treatise,s describes the diagnostic problem when both hysteria and epilepsy must be considered-that is, “. inadequate experience or excessive bias, or both, often prevent a right judgment. Decision may be deferred with expectation that time will tell. I t doesn’t always do so and many a person comes to mind whose diagnosis, even after years of observation, remains uncertain. ” Perhaps the term “hysterical” itself contributes to some of the confusion. Cherry9 states that the more frequently and widespread a term is used, the less information it conveys. We feel that the word hysterical, which has been used for many years and in different connotations, may suffer in this regard when applied to epilepsy. Instead, the term “pseudoseizure” is preferred because it calls to mind the concept of an epileptic seizure, and, at the same time, its prefix indicates that it is not genuine. Thus, a pseudoseizure is a clinical event which supei-lkially resembles an epileptic attack, but, under closer scrutiny, is found lacking in an essential epileptic component, such as a concomitant electroencephalographic dysrhythmia, or possessing a feature not compatible with epilepsy, such as the characteristic of being precipitated, modified, or stopped by a simple command, a hypnotic suggestion, or the withdrawal of the attention of observers. The neurologist working with epileptic patients recognizes the practical problems caused by pseudoseizures. These problems range from establishing the diagnosis in a new patient to determining when pseudoseizures are falsely increasing the seizure count in those previously diagnosed epileptic patients who report back at intervals. If pseudoseizures are misdiagnosed in the new patients, improper treatment will result. If pseudoseizures are falsely increasing the seizure count in the proved epileptic patients, the result may be too much and too many anticonvulsant drugs with the implied iisk of drug reactions.
Association of anthropometric measures and cardio-metabolic risk factors in normal-weight children and adolescents: the CASPIAN-V study

Abstract Background: The present study aims to explore the association of anthropometric indices and cardio-metabolic risk factors in normal-weight children and adolescents. Methods: This cross-sectional nationwide study was conducted in 2015 among 4200 Iranian school students aged 7–18 years. They were selected using a multi-stage cluster random sampling method. Anthropometric indices and cardio-metabolic risk factors including fasting blood glucose (FBG), lipid profile and blood pressure (BP) were measured using standard protocols. Results: The response rate was 91.5%. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) had a significant positive correlation with waist circumference (WC), hip circumference (HC) and body mass index (BMI) in boys and girls. HDL-C had a significant inverse correlation with WC, HC and BMI in boys. For each unit increase in WC, HC and BMI, the risk of elevated DBP significantly increased by 2%, 1% and 11%, respectively. Likewise, for each unit increase in WC, HC and BMI, the risk of elevated BP significantly raised by 2%, 1% and 10%, respectively. For each unit increase in WC, the risk of metabolic syndrome increased by 7%. Conclusions: Anthropometric indices are considered an easy, non-invasive tool for the prediction of cardio-metabolic risk factors in normal-weight children and adolescents.
Towards Agility: Definition, Benchmark and Design Considerations for Small, Quadrupedal Robots

Agile quadrupedal locomotion in animals and robots is yet to be fully understood, quantified or achieved. An intuitive notion of agility exists, but neither a concise definition nor a common benchmark can be found. Further, it is unclear, what minimal level of mechatronic complexity is needed for this particular aspect of locomotion. In this thesis we address and partially answer two primary questions: (Q1) What is agile legged locomotion (agility) and how can we measure it? (Q2) How can we make agile legged locomotion with a robot a reality? To answer our first question, we define agility for robot and animal alike, building a common ground for this particular component of locomotion and introduce quantitative measures to enhance robot evaluation and comparison. The definition is based on and inspired by features of agility observed in nature, sports, and suggested in robotics related publications. Using the results of this observational and literature review, we build a novel and extendable benchmark of thirteen different tasks that implement our vision of quantitatively classifying agility. All scores are calculated from simple measures, such as time, distance, angles and characteristic geometric values for robot scaling. We normalize all unit-less scores to reach comparability between different systems. An initial implementation with available robots and real agility-dogs as baseline finalize our effort of answering the first question. Bio-inspired designs introducing and benefiting from morphological aspects present in nature allowed the generation of fast, robust and energy efficient locomotion. We use engineering tools and interdisciplinary knowledge transferred from biology to build low-cost robots able to achieve a certain level of agility and as a result of this addressing our second question. This iterative process led to a series of robots from Lynx over Cheetah-Cub-S, Cheetah-Cub-AL, and Oncilla to Serval, a compliant robot with actuated spine, high range of motion in all joints. Serval presents a high level of mobility at medium speeds. With many successfully implemented skills, using a basic kinematics-duplication from dogs (copying the foot-trajectories of real animals and replaying the motion on the robot using a mathematical interpretation), we found strengths to emphasize, weaknesses to correct and made Serval ready for future attempts to achieve even more agile locomotion. We calculated Serval’s agility scores with the result of it performing better than any of its predecessors. Our small, safe and low-cost robot is able to execute up to 6 agility tasks out of 13 with the potential to reach more after extended development. Concluding, we like to mention that Serval is able to cope with step-downs,
Drug disposing behavior and awareness of the concept of ecopharmacovigilance among the medical faculty

Background: The ever-increasing impact of drugs on the environment has added an altogether new dimension of monitoring, assessing and documenting the known and unknown drug effects on our fragile environment in the form of ecopharmacovigilance. This study was carried out to document the drug disposing behavior and awareness of the concept of ecopharmacovigilance among the medical faculty of a tertiary care Medical Hospital. Methods: A detailed, structured, anonymous questionnaire consisting of both open and close ended essential queries on drug disposal practices was prepared and response obtained from the participants which included an agglomeration of teaching faculty and the clinicians of various disciplines of the Institute. Results: 97.87% of the participants obtained drugs in excess which included a majority of solid (68.12%) and liquid (31.88%) dosage forms. The maximum medicines obtained in excess included analgesics and antipyretics (89.36%), anti-asthmatics (15.22%), and anti-emetics (13.48%). 82.8% of the respondents were unaware of the proper drug disposal technique and 94.7 % of the respondents practiced open disposal of the drugs. Conclusions: An abysmally low level of awareness about ecopharmacovigilance and unhealthy, irrational method of drug disposal was documented in our study. Appropriate training of those who handle drugs in hospitals and healthcare establishments is the need of the hour.
Influenza vaccine effectiveness in children: a retrospective study on eight post-pandemic seasons with trivalent inactivated vaccine

Background and aim of the work: The global burden of disease attributable to seasonal influenza virus in children is difficult to quantify. Children with chronic medical conditions and healthy children may experience severe or fatal complications. Aim of the study was to estimate the influenza vaccine effectiveness (VE) in a cohort of outpatient children. Methods: From 2010 to 2018, a Pediatrician of Parma from the InfluNet network of Emilia-Romagna Region, performed nasal/throat swabs on every child with Influenza-like illness at least 14 days from the vaccination with trivalent vaccine. VE estimates against influenza season, virus type and subtype and age group were evaluated using a test-negative design. Results: 2,480 swabs were performed. The 57.6% of the analyzed swabs were positive for influenza viruses. Type A (57%) and type B viruses (43%) co-circulated. The 37.1% of type A viruses belonged to subtype A(H3N2), 19.4% to subtype A(H1N1)pdm09. The subtype A(H3N2) was prevalent among children up to 23 months (42.4%) while the type B in the 2-4 (40.7%) and 5-16 year old age groups (49.4%). Overall, 19.9% of the children were vaccinated. The highest prevalence of vaccinated subjects was found in children aged 5-16 (30.5%). The VE against subtype A(H1N1)pdm09 was 63% (95%CI 42.6-76.0), against type B 27.5% (95%CI 7.9-42.9) and against subtype A(H3N2) -14.3% (95%CI - 46.0-10.7). Conclusions: Our findings represent a useful contribution to the ongoing debate about the appropriateness of including influenza vaccination for healthy children, 6 months and older, in the updating National Vaccine Prevention Plan (PNPV).
