High prevalence of allergic diseases among children and their close relation with quality of the environment require new approaches to organizing diagnostic and prevention activities. Our research objects were 247 children attending pre-school children facilities (PSCF). It was detected that children who permanently lived and/or attended a pre-school facility for not less than three years under long-term chemical aerogenic exposure to manganese and nickel compounds in low doses (0.17–0.23 MPC average daily) had contents of these metals in their blood that were 1.9–2.0 times higher than the same parameter in children from the reference group and 1.7–2.1 times higher than background level in the region. Pre-school children with their biological media being contaminated with nickel and manganese compounds suffered from atopic dermatitis, allergic rhinitis, and bronchial asthma 1.3–4.5 times more frequently (0.23R20.73; 59.2F388.1; р≤0.001). Allergic diseases associated with aerogenic exposure to chemicals with sensitizing power have certain pathogenetic peculiarities such as active overall inflammatory reaction; sensitization in 54–86% children (the parameter is 1.5–4.3 times higher than in the reference group); cellular metabolism disorder; depletion of antioxidant protection resources in 72% children; deficient activity of phagocytic and humoral section in immunity (1.2 times lower than in the reference group); cytokine regulation disorders (2.4–2.5 time difference); reduced expression of a receptor that induces activation apoptosis; stronger sympathetic influence on heart rate modulation in 26.0% children. Basing on statistical analysis and model making, we determined markers that showed occurring allergic reactions caused by aerogenic exposure to manganese and nickel compounds. These markers are targets for prevention activities; they include growth in allergic pathologies prevalence; these pathologies occurring together with chronic inflammatory-proliferative diseases and disorders in the vegetative nervous system; increased contents of leukocytes, eosinophils, and immunoglobulin E specific to nickel in blood; a decrease in phagocyte number and contents of IgM, IgА in blood serum (0.07≤R2≤0.74; 19.3≤F≤713.2; р≤0.0001).


We show that radial distortion of images invalidates the geometric constraint on which self-calibration of a rotating camera is based on, that is, 3D lines drawn between matched features all intersect at the rotation centre. We develop a geometric picture showing how radial distortion violates this constraint and discuss the implications for self-calibration of a rotating camera. In particular we show that the behaviour of self-calibration is markedly different for pin-cushion and barrel distortion, the latter causing self-calibration to be unreliable or to fail completely. A method is presented for automatically estimating the radial distortion over a sequence of images, when both distortion and camera internal parameters vary. We discuss when such an approach will work and whether accurate automatic calibration of a rotating camera is really possible.


The analytical methodology of 1,2,3,4,5,6-hexachlorocyclohexane isomers residing in an aquatic environment was investigated with gas chromatography electron impact mass spectrometry selected ion monitoring as the determinative technique. An extraction method with a macroreticular Amberlite XAD-2 resin column was successfully developed and the extract was subjected to the gas chromatography electron impact mass spectrometry selected ion monitoring system. Ions at m/z 219 [MHCl2+2]+˙ from residual 1,2,3,4,5,6-hexachlorocyclohexane isomers and m/z 224 [M2HCl2+2]+˙ from dual laboratory-synthesized deuterated internal standards were monitored for the estimation. Linearities of individual 1,2,3,4,5,6-hexachlorocyclohexane isomers with gas chromatography electron impact mass spectrometry selected ion monitoring were much wider than those with gas chromatography electron capture detection, and it could be said that dilution or concentration of the sample extract was commonly unnecessary. In addition, carrier effects of deuterated internal standards with representative water samples and selectivity of the method in comparison with gas chromatography electron capture detection were clearly shown. In field experiments, total 1,2,3,4,5,6-hexachlorocyclohexane levels were from 166.54 to 7.40 parts per trillion (ng L−1).


At the end of 2019, SARS-CoV-2 infection began to advance rapidly. By March of 2022, SARS-CoV-2 had infected approximately 30 million people in Brazil, with more than 3 million cases and almost 27,000 deaths in the state of Ceará. The city of Fortaleza, one of the seven largest capitals in Brazil, had the second highest mortality rate in the first year of the COVID-19 pandemic in the country, second only to that in the city of Manaus.(2)


Abstract Analysis of a single strand 36 t thin slab caster tundish has been conducted with different sets of furniture using a three-dimensional computation fluid dynamics model taking heat losses into account. Five distinct and optimised cases and a base case were used for simulation. The cases were built considering tundish furniture that is readily and economically available and provides ease of maintenance, thus targeting an optimal set of furniture. The performance of different sets of furniture was assessed based on residence time parameters like plug volume fraction, mixed volume fraction, dead volume fraction, etc. Other performance indicators used in the analysis were temperature distribution, observing cold spot, surface velocity and nature of flow in the tundish. Insight from the base case reveals the desired flow characteristics that help to achieve the target performance. Inferred results suggested the use of a turbulence inhibitor in combination with a dam as the optimal set of furniture. Use of a non-isothermal model is important, as it was found that even a small change in temperature (2·3°C) plays a vital role in the fluid flow inside the tundish.

In this paper we proposed a text-independent (TI) speaker identification method that suppresses the phonetic information by a subspace method, under the assumption that a subspace with large variance in the speech feature space is a 'phoneme-dependent subspace' and a complementary subspace of it is a 'phoneme-independent subspace'. Principal Component Analysis (PCA) is employed to construct these subspaces. Gaussian Mixture Model (GMM)-based speaker identification experiments using both the phonetic information suppressed feature and the conventional Mel-Frequency Ceptrum Coefficient (MFCC) were carried out. As a result, the proposed method has been proven to be effective for decreasing the identification error rates.


This study deals with Vector Network Analyser based source-load-pull measurements. While a lot of papers demonstrated the influence of harmonic load impedances on PAE performances and time domain RF waveforms shaping, the harmonic source-pull topic has been a little bit less addressed. When using a traditional power meter based source/load-pull bench, source pull measurements are mandatory. Indeed, for a fixed power level and a given set of load impedances, the source pull optimization highlights the conditions to match the transistor's input access. Nowadays, modern Vector Network Analyser based source-load pull systems provide the direct measurements of the transistor input impedance. Thus, from the theoretical definition of any arbitrary source impedance, the mismatch calculus between input and source impedances is possible. It gives rise to a new kind of virtual source pull measurements. Some of us have called this method "magic source pull". This method and its limitations will be explained, comparison between traditional source pull and Vector Network Analyser based "magic source pull" will be provided.

Paraguay has been neglected in International Relations, globally and regionally. This is largely because of its limited bargaining power. It is landlocked, territorially small, its economy is marked by informality (and illegality), its production capabilities limited to the primary sector, and its international trade is inexpressive, regionally or globally. Yet, despite these power asymmetries, it is incorrect to say that the country is irrelevant in the regional political game. In fact, its importance comes, partially, from these structural problems. Paraguay poses a challenge to Southern Cone regional security. It is one of the countries with most contraband activity, money laundering, and organized crime in the region. This article analyzes Paraguay's foreign relations from the creation of Mercosur to the present. Three fundamental elements are addressed: Paraguay's relationship with Mercosur and its members; Paraguay's relationship with the United States; and the possible implications of Venezuela joining Mercosur


Abstract The present study deals with axisymmetric circular/annular disks made of three-phase multi-scale hybrid laminated nanocomposite under distributed static loadings. The structure is placed on Winkler-Pasternak substrate with friction effects. Initial stress is also considered in the composite structure. The mathematical model is prepared using three-dimensional elasticity theory (3D-elasticity theory). The derived differential equations are solved by employing the semi-analytical method of state-space-based differential quadrature method (SS-DQM) to obtain the stress and displacement fields of the composite structure. In the numerical analyses, a comprehensive parametric study is performed to observe the effects of some geometrical and physical parameters on bending characteristics of composite circular/annular disks.


Regional low carbon development index has important referenced value for measuring and comparing the low carbon development in different regions objectively.Drawing on the ideas of Human Development Index and spatial distance method,this paper constructs regional low carbon development index model from three dimensions of low carbon economy,low carbon energy efficiency,low carbon environment.Then using the actual data of China's 30provinces in 2005-2011,this paper contrastively studies the dynamic changes and regional differences of low carbon development in each district.The results found that average value of Beijing is highest,Ningxia is lowest during the sample period.National lowcarbon development level rises steadily,but the imbalance between regions is worsening.The difference of top 30%regions of low carbon development is narrowing,the imbalance between the lowest 30% regions is gradually stabilized.The eastern economic zone has the highest level of low carbon development,followed by the central and western.Clustering analysis results show that it is more appropriate to be divided into high,medium and low categories in accordance with the low carbon development level of different regions.

marriage in which we are similarly aged, pigmented, and moneyed. What kind of marriage do we have when the Department of English and the Department of Speech join in the teaching of rhetoric? Early issues of a four-year-old quarterly, Philosophy and Rhetoric, pursued some of the grounds for answering the question. Lloyd Bitzer in "The Rhetorical Situation" defines the setting for rhetoric as including an exigence, or a pressing problem, which may be modified by discourse which can constrain (affect) human action. In his analysis there must be the problem, the audience, and the constraints. Then, in his discussion of these essential features of the rhetorical situation he is clear that rhetorical discourse is "called into existence by situation," that the situation invites and prescribes a "fitting response" and that these problems, events, objects, persons and relations are all real-not hypothetical or fictional. In writing of these things he finds sharp contrasts between his vision of rhetoric and various species of non-rhetoric which may be confused with rhetoric.1 C. S. Baldwin in 1924 said that rhetoric is concerned with movement that is


Two epistylid peritrichous ciliates collected from the littoral aquatic plants at pond in a suburb of Ulsan, Korea were identified as Epistylis plicatilis Ehrenberg, 1831 and E. hentscheli Kahl, 1935. The description was based on the observation of living specimens and protargol impregnated specimens. This study is about redescription compared with original description. These species have not been reported in Korea and their characteristics are as follows: E. plicatilis is thin, long funnel form and has compact stalk, while E. hentscheli is unsymmetrical bell form and has hollow stalk.


INTRODUCTION
Trauma accounts for 20% of deaths in pregnant women. Injury characterisation and outcome in pregnant women following trauma is poorly described. To understand and inform optimum care of this key injury population, a study was conducted using the Trauma Audit Research Network (TARN) database.

METHODS
In total, 341 pregnant and 26,774 non-pregnant female patients aged 15 to 46 years were identified for comparison from the TARN database. Mortality, cross-sectional imaging, blood product administration and EQ-5D scores were compared between the two groups. Mechanism of injury, Injury Severity Score (ISS) and mortality rate before and after the creation of regional trauma networks were reported for pregnant patients.

RESULTS
Pregnancy was recorded in 1.3% (341/27,115) of included patients, with the most common cause of injury being road traffic collisions. A reduction in crude maternal mortality was observed over the course of the study period (7.3% to 2.9%). Baseline mean EQ-5D (0.47) and EQ-VAS (54.08) improved to 0.81 (p < 0.001) and 85.75 (p = 0.001), respectively, at 6 months following injury.

CONCLUSION
The incidence of trauma in pregnancy is small and mortality in injured pregnant women decreased over the study period. Pregnant patients have significantly improved patient-reported outcome measures 6 months after injury although this is limited in impact because of poor response rates and outcome reporting. Construction and validation of tools aiding in outcome reporting will help considerably in understanding further gains in the care of pregnant women.

BPSK-PM is a modulation mechanism in which BPSK is used as its sub-carrier modulation mode and PM as its main-carrier modulation mode.This mechanism makes the spectrum of the modulated telemetry signal separate from that of carrier signal,while the residual carrier can be applied in A/V measuring and tracking.This paper firstly introduces the BPSK-PM modulation mechanism and analyzes the spectrum characteristics of its modulation signal,and then proposes a mid-frequency digital reception and carrier acquisition scheme according to the specific application.The carrier acquisition scheme is divided into a frequency searching part based on FFT and a frequency tracking part based on digital frequency-lock loop technology,which are analyzed in details.Finally,this paper shows a practical application of the carrier acquisition scheme,and the effectiveness of the scheme has been preliminarily verified in the Martian deep-space exploration of China.


A creative low-cost and compact mechanical device that mimics the rapid closure of the pistol shrimp claw was used to conduct electrochemical experiments, in order to study the effects of hydrodynamic cavitation on the corrosion of aluminum and steel samples. Current-time curves show significant changes associated with local variations in dissolved O2 concentration, cavitation-induced erosion, and changes in the nature of the surface corrosion products.


Anomalous magnetization curves observed under the strong pulsed magnetic fields up to 520 kOe are understood with itinerant electron metamagnetism. From the results of Sc(Co 1- x Al x ) 2 the critical field of the transition and the spontaneous moment after the transition of ScCo 2 can be estimated to be a few megagauss and about 0.4 µ B /Co, respectively. These are consistent with recent theoretical results.
