A Low Pulling Effect Self-Isolated Harmonic Active Radiator for Millimeter-Wave Internet-of-Things Applications

A low pulling effect self-isolated harmonic active radiator operating around 28 GHz is proposed, investigated, and demonstrated in this article. Thanks to the inherent self-isolation property of a feedback loop of the proposed active radiator, a superiority of pulling effect mitigation, harmonic output, and simple structure is achieved. As part of the loop, a partially air-filled dual-mode substrate integrated waveguide cavity with a dielectric-loaded broadside slot is designed to realize the functions of resonators, harmonic diplexers, and antennas concurrently. The radiator oscillates at a fundamental frequency which is set by the first mode of the cavity resonator, and the generated second harmonic signal is extracted and radiated by the diplexer and antenna functions, respectively. Self-isolation is achieved because a pulling signal is attenuated by the synergetic effect of the reverse isolation and harmonic separation of the loop amplifier and diplexer, respectively. Measured results of a fabricated prototype show a maximum equivalent isotropic radiated power of 15 dBm at 28.15 GHz and a phase noise of −108 dBc/Hz at 1 MHz offset. Load pulling and injection pulling are reduced by a factor of 10 and 17, respectively, compared with an active radiator transmitting a fundamental signal around 28 GHz. Such a robust and compactly integrated structure is a good candidate for low-cost millimeter-wave Internet-of-Things applications in connection with identification, sensing, tracking, and communication.

Los conceptos comprendidos en dichos registros abarcan estática, cinemática, dinámica, trabajo y energía. Los resultados obtenidos nos permiten decir que aproximadamente para la quinta parte de los estudiantes de esta muestra, la toma de apuntes en la clase de física constituye una estrategia metacognitiva independientemente que el proceso se encuentre automatizado por la práctica.
The dynamic effects of car ownership determinants in the Netherlands

This thesis discusses the dynamics of some main household car ownership determinants in the Netherlands between 2005 and 2015. First of all, a literature review is made to look for existing relationships and dynamic effects. Next, three models were created with household car ownership as dependent variable. The models were formed around the three main determinants: income, urban form and household composition. Adding a interaction between the determinant of interest and the year of observation, the dynamic effects were estimated with the pooled ordinary least squares method. The graphs show a dynamic effect for both income and household composition, where the income effect seems to follow the business cycle. Household composition showed decreasing importance in determining household car ownership. In contradiction, urban form showed no significant dynamic effect between 2005 and 2015. The author recommends further analysis with some model improvements to confirm found effects and find possible causes for the trends found. Also, other car ownership determinants might be interesting to check for dynamic effects. For example, parking supply and psychological variables regarding car ownership.
GeoTorch: a spatiotemporal deep learning framework

Deep learning frameworks, such as PyTorch and TensorFlow, support the implementation of various state-of-the-art machine learning models such as neural networks, hidden Markov models, and support vector machines. In recent years, many extensions of neural network models have been proposed in the literature targeting the applications of raster and spatiotemporal datasets. Implementing these models using existing deep learning frameworks requires nontrivial coding efforts from the developers because these extensions either are hybrid combinations of various categories of neural network models or differ extensively from state-of-the-art models supported by existing deep learning frameworks. Moreover, existing deep learning frameworks lack the support for scalable data preprocessing required to form trainable tensors from raw spatiotemporal datasets. To enable easy implementation of these neural network extensions, we present GeoTorch, a framework for deep learning and scalable data processing on raster and spatiotemporal datasets. Along with the state-of-the-art spatiotemporal models and ready-to-use benchmark datasets, we propose a data preprocessing module that allows the processing and transformation of spatiotemporal datasets in a cluster computing setting.
Public awareness, attitudes and beliefs about intellectual disability: a Sikh perspective

Part 1 is a literature review of South Asian perspectives on intellectual disability. Thirty-one papers are reviewed according to seven geographical locations. South Asian needs, beliefs and knowledge about intellectual disability are highlighted. The limitations of the review are discussed as well as clinical implications and implications for future research. Part 2 reports an empirical study looking at public awareness, attitudes and beliefs about the causes of intellectual disability amongst the UK Sikh community. The association between socio-demographic factors and these variables are examined and comparisons are made with a matched white British sample, through the use of a two-group comparison design. The results are discussed highlighting on the whole similarities between the groups. Part 3 is a critical appraisal which focuses on the process of carrying out research with the UK Sikh community. Reflections on the literature review are discussed with reference to the scope of the review, the quality of the studies included and reasons for omitting potentially relevant articles. Key dilemmas and difficulties experienced whilst setting up the study are explored which focus on promoting the study and recruiting participants. Finally issues concerning data interpretation are discussed.
Does LeTID occur in c-Si even without a firing step?

It is shown that a non-fired B-doped floatzone silicon sample coated with SiNx:H may show severe bulk related degradation and regeneration during illuminated treatment at elevated temperature. It is discussed that the likely cause is light and elevated temperature induced degradation (LeTID) in the silicon bulk. Firing is found to modulate the extent of LeTID so that degradation may either be weaker or stronger compared to the non-fired sample depending on firing parameters. A sample which was annealed instead of fired is found to be stable for up to 1,000 h of treatment time.
A 9.4 MHz, 0.011 mm², 107.6 ppm/°C single-port RC oscillator with temperature compensation

A 9.4 MHz single-port RC oscillator is introduced using 0.18 μm CMOS technology, which can be applied in cryogenic medical instruments. By combining a comparator with negative resistors and optimizing temperature coefficients of composite resistors, we are able to reduce the sensitivity of frequency to temperature. The proposed oscillator improves the stability of the frequency without significant increase in area, occupying only 0.011 mm². The measured frequency variation is less than ±0.5% from -65°C to 25°C and ±0.35% from 3.8V to 4.2V.
Modulation of Interleukin-17 By Tumor Necrosis Factor Alpha During the Immune Response to Borrelia Burgdorferi

Arthritis is one of the main complications of late-stage Lyme borreliosis. Cytokines play an important role in the persistent inflammation that is elicited by the causative agent of disease, Borrelia burgdorferi. Tumor necrosis factor alpha (TNF-alpha) is a pro-inflammatory cytokine that is induced by B. burgdorferi and that has been implicated in development of arthritis. However, in a mouse model of Lyme arthritis, treatment with anti-TNF-alpha; antibodies increased the severity of disease. By contrast, injection of recombinant TNF-alpha; ameliorated arthritis in this model. These findings suggested that other factors might be involved during the development of Lyme arthritis. One possible factor may be interleukin-17 (IL-17), a pro-inflammatory cytokine mainly produced by T helper 17 cells. IL-17 has been implicated in the development of Lyme arthritis. Treatment with anti-IL-17 antibodies reduces the inflammatory outcome in animal models of disease. However, it is not known how TNF-alpha; affects the response of IL-17 to B. burgdorferi. The hypothesis of this thesis is that TNF-alpha; will regulate the immune response to B. burgdorferi infection by decreasing IL-17 production. Modulation of IL-17 during the immune response to B. burgdorferi was analyzed in wild-type and interleukin-10 (IL-10)-deficient mice treated with anti-TNF-alpha; antibodies. We found that anti-TNF-alpha; antibody treatment increased paw inflammation in both wild-type and IL-10 deficient mice. In addition, cell cultures from B. burgdorferi-infected, wild-type mice treated with anti-TNF-alpha; antibodies typically produced a greater amount of IL-17 than untreated controls, suggesting that TNF-alpha; decreases IL-17 levels following infection. Additional treatment of anti-TNF-alpha; antibody-treated mice with anti-IL-17 antibodies lessened the severity of paw swelling. Our results indicate that TNF-alpha; can play a protective role during the immune response to B. burgdorferi infection by restraining the production of IL-17.
Effect of Different Additives on Reaction Characteristics of Fluorapatite During Coal-Based Reduction of Iron Ore

In the coal-based reduction of high phosphorus oolitic hematite, it is particularly important to study the mechanism of phosphorus regulation during the formation of iron metals for the efficient development and utilization of iron ore. In this study, the thermodynamics of the coal-based reduction process of fluorapatite in different mineral systems, effect mechanism of the reduction degree, kinetics, mineral composition, and morphology of structural evolution samples were systematically investigated using FactSage software, single factor analysis, the isothermal method, X-ray diffraction (XRD), scanning electron microscope (SEM), and an energy dispersive spectrometer (EDS). Thermodynamic analysis indicates that the effect of the SiO2–Fe2O3–C system on reducing the initial reduction temperature of fluorapatite was stronger than that of the Al2O3–Fe2O3–C system. The effect mechanism of the reduction degree demonstrates that increasing the dosage of silica, iron oxide, carbon, reduction time, and reduction temperature could promote the reduction reaction of fluorapatite under certain conditions. Dynamics analysis shows that the best kinetic mechanism functions of the SiO2–Fe2O3–C system and the Al2O3–Fe2O3–C system were A1/3 = 1/3(1 − α)[−ln(1 − α)]−2 and A1/2 = 1/2(1 − α)[−ln(1 − α)]−1, respectively. The activation energy and pre-exponential factor of the reduction kinetics equation in the system containing silica were significantly lower than that in the system containing alumina, which explained that the catalytic effect of silica on the reduction of calcium fluorophosphate was far greater than that of alumina. XRD and SEM/EDS analysis indicate that the solid–solid reaction of alumina, silica, iron, and fluorapatite occurred during the reduction process, while calcium aluminate, calcium silicate, and calcium oxide were formed at the contact point. Among them, iron could absorb P2 gas so that it played a greater role in promoting the reduction of fluorapatite. Increasing the reduction temperature and prolonging the reduction time were beneficial to the reduction of fluorapatite.
Leadership in Compassionate Care: Executive Summary- Enhancing patient care by promoting compassionate practice.

The Leadership in Compassionate Care Programme (LCCP) commenced in 2007 as a three year programme of work. Initial funding was received from a private benefactor and the two organisations involved in the programme (NHS Lothian and Edinburgh Napier University) were required to match this funding. The work of the programme developed beyond the initial funding. A Lead Nurse and four Senior Nurses were appointed to deliver the programme and a wide range of staff from both organisations were actively involved and participated with this team. The impetus for this programme arose from local and National concerns about care focussed on patients and their relatives experiencing a lack of empathy and compassion, acknowledging that it is often small acts of kindness and a human connection, alongside clinical competence that is appreciated by patients and relatives
Brain tumors; their biology and pathology

an internationally recognized authority, the reviewer can only repeat his comments upon the earlier edition, for the main body of the work remains unchanged. In a comparatively short compass the author has managed to achieve a well balanced and discriminating systematic condensation of a huge literature and of his own wide experience in the pathology of brain tumors. The book is addressed to the needs and interests of clinicians. The first half of the work is devoted to the general characteristics of brain tumors : their classification, structure, age and sex incidence, preferential localization, and displacements of intracranial structures. These topics are discussed always with their diagnostic and prognostic significance in mind. Although the author's classification of the neuroepithelial tumors follows closely the histogenetic one of Bailey and Cushing, he insists rightly upon the importance of avoiding too great a dependence upon the cell type alone for morphological diagnosis, and emphasizes the neces¬ sity of giving full consideration to the total archi¬ tecture of the tumor and its manner of growth. The remainder of the book is concerned with the gross and microscopic anatomy of the indi¬ vidual tumor types, illustrated by well chosen photographs of excellent technical quality. The new edition has been revised by the addition to the appropriate chapters of a brief resume of the re¬

Parálisis cerebral: concepto y registros de base poblacional

Introduccion. La paralisis cerebral (PC) es la causa mas frecuente de discapacidad motora en la edad pediatrica. Desde hace decadas, varios paises desarrollados han establecido registros que han servido para estudiar la PC con base poblacional. En Espana, en cambio, se ha prestado escasa atencion a la epidemiologia de la PC. Objetivo. Revisar el concepto actual de PC y suscitar el interes por la investigacion en PC a partir de la experiencia de otros paises. Desarrollo. Las distintas definiciones de PC engloban secuelas motoras secundarias a una lesion cerebral puntual que acontece en un cerebro en desarrollo. Los registros de PC nacieron con el objetivo de monitorizar la prevalencia de la PC y planificar de forma adecuada la asistencia a los pacientes. En la ultima decada se han desarrollado proyectos coordinados entre varios centros, lo que proporciona una poblacion de estudio mayor y minimiza la confusion terminologica. En esta linea, destaca el grupo europeo de PC (SCPE), que reune informacion sobre ninos con PC de 15 paises. Desde el ano 2003, Espana participa en este proyecto a traves de un grupo de investigadores del Hospital 12 de Octubre de Madrid. Conclusiones. La PC es una realidad compleja desde su propia definicion. Estudiar la PC con base poblacional en Espana deberia contribuir a renovar el interes en nuestro medio por esta patologia.
An Investigation of Diesel PM Particle Morphology Using TEM and SEM

This research investigates the effect of engine load and combustion mode on the size, shape and microstructure of PM particles of two diesel engines using a scanning mobility particle sizer (SMPS), and electron microscopes including scanning electron microscope (SEM) and transmission electron microscope (TEM). The effect of engine load on the morphology of PM particle was investigated using a 2004 MACK MP7-355E heavy-duty diesel engine. The effect of combustion mode on the morphology of the PM particles was preliminarily examined using 2005 Opel 1.9 L light-duty diesel engine. The SEM images were processed using ImageJ V: 1.44o software to obtain a set of parameters based on the projected area. These include the maximum length, maximum width, project area equivalent diameter, shape descriptor, fractal dimension, and the size of primary PM particles. The TEM images were processed to obtain the micro-structure and chemical composition of PM particles. The SEM images obtained in this research revealed the diverse morphology of PM particles formed in heavy-duty diesel engine. The operation at low load tends to form small sphere-like PM particles compared to medium and high load operation featured with large and chain-like PM particles. The projected area equivalent diameter of PM particles observed was in the range of 43.7 to 167.4 nm and 66.4 to 688 nm for operation at 20% and 100% load respectively. The PM particles smaller than 43 nm observed using SMPS were not observed using SEM methods. The projected area equivalent diameter of PM particles from the light duty engine during PCCI mode was smaller in size compared to the PM particles observed under normal operation. The fractal dimension of this heavy-duty diesel engine observed was 1.82, indicating spherical PM particles. The fractal dimension for the light duty engine was 1.65 and 1.7 for the traditional diesel and PCCI mode, respectively, indicating more spherical particles during PCCI mode. The TEM images were processed to obtain the compositions and microstructure of the PM particles. The PM particles observed contain mainly carbon as well as inorganic and metallic elements such as Ca, Mg, Zn, P and Si from engine oil, Al and Fe from engine wear, and S from fuel and lubricating oil. The compositions of PM particles were also found to vary significantly from particle to particle observed under identical operating conditions indicating the random burning of lubrication oil droplets and its effect on the formation of PM particles. The microstructure of primary particles from the heavy duty diesel engine exhibited two types of An Investigation of Diesel PM Particle Morphology Using TEM and SEM
The Hierarchy of Nutraceutical Markets 2000+

ABSTRACT Despite the complexities of market maturation, ongoing segmentation and the mainstreaming of positive eating and self care, today's nutraceutical arena finally offers manufacturers the option of a solid, but diverse, hierarchy of product opportunities. The risk of entry has been lowered. As discussed in this article in detail, traditional manufacturers can participate in major health markets like cancer and heart disease prevention simply by adding recommended levels of FDA approved traditional health promoting ingredients. Others can choose to run the continuum from fortification and increased bioavailability to performance enhancement, risk reduction and disease intervention. Emerging market segments, market trends, consumer attitudes and recommendations for major market opportunities are presented. The self care movement and the shift to wellness, prevention and health maintenance are also a prime focus.
Chemical, physical, and microbiological characterstics of various sources of water in and around Addis Ababa

Abstract: Every month, from November 1996 to October 1997, water samples from 18 different sites were collected. The samples belong to the following categories: reservoirs that supply Addis Abeba's tap water (Lakes Gefersa and Legadadi) city taps, city swimming pools, Ambo Mineral Water, rain water, Akaki and Bulbula Rivers and Lake Aba Samuel. Four different physical variables (PH, Temperature, Total Dissolved Solids, and Conductivity) and concentration of 19 different cations, anions, and CO2 were determined. The results revealed no health risk except the high concentration of Cr3+, Cd2+, Fe3+, Pb2+, Mn4+ and Nitrate in Akaki and Bulbula Rivers samples. The water from these rivers is not consumed by city residents although they are used by rural communities to the east and southeast of Addis Abeba. Similarly, the two swimming pools included in this study had high TDS,HCO3- and fluoride content as well as slightly increased Cd2+, Pb2+ and Cu2+ levels. On the other hand, parasitological and bacteriological analyses revealed all sources were clean except Akaki, Bulbula and Aba Samuel. Infact these results suggest drinking waters of Addis Abeba are safe, while recreational waters of the city are acceptable for the purpose they serve. However, in view of polluted rivers flowing out of Addis Abeba and Lake Aba Samuel, methods of minimizing the health risks they pose are suggested. [Ethiop. J. Health Dev. 1999;13(3):239-246]
Impact of Urbanisation on New Zealand Freshwater Quality

Urban waterways represent less than 1% of the total river length in New Zealand. However, they are the most visible of all rivers, as 86% of New Zealanders live in urban areas. Urban waterways are impaired due to elevated levels of pathogens, turbidity, nutrients and heavy metals originating from anthropogenic activities. In addition to being conduits of storm water run-off from urban areas, some urban waterways also receive discharges from wastewater treatment plants and combined sewage overflows, thus greatly reducing their capacity to provide ecosystem services such as recreation, tourism, biodiversity and mahinga kai. This article summarises the state of New Zealand’s urban freshwater quality, the major drivers of pollution, and mitigation measures needed to restore urban waterways.
Los barorreflejos arteriales cardiovagal, cardiosimpático y vasosimpático y el control neural de la presión arterial a corto plazo

Introduccion. Los factores que modulan la presion arterial a corto plazo se encuentran puntualmente regulados para mantenerla dentro de valores de referencia. Esto se logra gracias a la existencia de mecanismos de autorregulacion, tanto humorales como nerviosos. Los mecanismos neurogenicos son reflejos y su resultado se observa en cambios de presion arterial de forma inmediata, latido a latido. Desarrollo. Los reflejos nerviosos cardiovasculares se encuentran mediados por los barorreceptores arteriales, a traves de los efectores cardiovagal, cardiosimpatico y vasosimpatico. El barorreceptor es estimulado cuando el volumen de sangre eyectado por el ventriculo distiende las paredes arteriales del seno carotideo y la aorta proximal y estimula los mecanorreceptores situados en la adventicia de estos vasos. El estimulo aferente viaja hasta el nucleo del haz solitario en el bulbo raquideo y otras areas en el puente donde se integran estos reflejos y la parte eferente genera cambios compensatorios en la frecuencia cardiaca y el tono del musculo liso vascular. Esta modificacion subita es la responsable de la variabilidad de la presion arterial latido a latido (corto plazo). Conclusion. Se realiza una revision sobre la historia, la fisiologia y los experimentos de los barorreflejos cardiovagal, cardiosimpatico y vasosimpatico y su influencia en la variabilidad de la presion arterial a corto plazo.
