Study of the relationship between ferritin serum and thyroid function

The present study including study effect of thyroid function on ferritin. In Thi-Qar province, Iraq. The sample include 30 from patients and 10 samples was control in four age categories was (25≥, 26-35, 36-45, 46-55) during the period from August 2021 to January 2022. The current study show TSH level increased in women suffering from hypothyroidism, while it was lowest in women suffering from hyperthyroidism, As for the (T3,T4) Hormone the highest level was with hyperthyroidism, but women with hypothyroidism had lower levels when compared to the control group. The ferritin level decreased in the age group (46-55), while T3 and T4 was higher in the age group (26-35), but TSH increased in women less than 25 year. As for the Hb highest level was age category (26-35) while lowest in age category (46-55).
Stability for bilinear time-delay systems with saturating actuators

The stability of a bilinear system with stated delay and saturating actuator is discussed. Delay-dependent sufficient conditions for the uniform asymptotic stability of the closed-loop systems via a memoryless static state feedback controller is developed. The matrix measure and comparison theorem are employed to investigate the problem. The results obtained omit solving the Lyapunov function or Riccati equation and is less conservative than the delay-dependent criterion for the same example when delay is small. The authors' result is demonstrated by an illustrate example.
Dielectric properties of microcrystalline cellulose/multi-wall carbon nanotubes multi-scale reinforced EVA/VeoVa terpolymer

Dielectric analyses were investigated on vinyl resin emulsion based on ethylene vinyl acetate/vinyl ester of versatic acid terpolymer (EVA/VeoVa) and its composites reinforced with microcrystalline cellulose and multi-wall carbon nanotubes. Dielectric spectra were measured in the frequency range from 10-1 Hz to 107 Hz and the temperature interval from -35°C to 130°C. Three dielectric relaxations were identified for the matrix. The first one, appearing at lower temperatures and higher frequencies, was associated with secondary β relaxation. The second one appearing above the glass transition temperature was attributed to the α relaxation due to the main glass transition of the terpolymer. The third dielectric relaxation appearing at higher temperatures and lower frequencies was attributed to α’ relaxation originating from the motion of more repeat units compared to the α one. The addition of the reinforcements into the matrix gave rise to three additional dielectric phenomena originating either from microcrystalline cellulose or matrix/reinforcement interfaces. Analyses of secondary dielectric relaxations at low temperatures by using the Havriliak-Negami model and those at high temperatures according to an adequate equivalent circuit model allowed probing reinforcement/matrix interactions. This dielectric study was complemented by the thermal, structural and morphological analyses based on differential scanning calorimeter (DSC), X-ray diffraction (XRD) and scanning electron microscope (SEM), respectively
Top-quark pair cross-section measurement in the lepton+jets channel

A measurement of the production cross-section for top quark pairs in pp collisions at p s =7 TeV is presented using data recorded with the ATLAS detector at the Large Hadron Collider (LHC). Events are selected in the lepton+jets topology by requiring a single lepton (electron or muon), large missing transverse energy and at least three jets. No explicit identification of secondary vertices inside jets (b-tagging) is performed. In a data sample of 35.3 pb 1 , 2009 and 1181 candidate events are observed in the µ+jets and e+jets topology, respectively. A simple multivariate method using three kinematic variables is employed to extract a cross-section measurement of 171±17(stat.) +20 17(syst.)±5(lumi.) pb.
Refractory microvascular angina in hypertrophic cardiomyopathy: a novel therapy?

We read interest the article by Jex et al. 1 of a case of refractory angina in the context of hypertrophic cardiomyopathy (HCM) and Type 2 diabetes mellitus. The authors report a long duration of follow-up and discuss the contribution of diabetes mellitus to the pathological process of HCM resulting in accelerated myocardial fibrosis and refractory angina secondary to coronary microvascular dysfunction (CMD) despite trials of at least four anti-anginal medications. The association between HCM and CMD is well known. Hypertrophic myocardium is often less vascularized resulting in a mismatch between myo- cardial oxygen supply and demand, and ischaemia is often seen as a circum-ferential perfusion defect on cardiac magnetic resonance imaging (MRI). 2 Few evidence-based anti-anginal therapies exist for these patients. Refractory serves to highlight
Newforms of half-integral weight.

The object of this paper is to generalize these results to higher level. Thus we want to study the space S£+1/2(4N) of cusp forms of weight fc + 1/2 on Γ0(4ΛΟ (Ν e N) which have a Fourier expansion s in (*). Because this will be our basic object of study, we n w break with tradition and redefine the level of a modular form of half-integral weight s N if the form satisfies a transformation law under Γ0(4Ν) and has a Fourier expansion s in (*); we also drop the "4" and the "+" and write Sk+i/2(N) instead * ^) i* °f T* (n). More generally, if χ is a DirichJet character
A compact solution to computational acoustics

This paper demonstrates that the linearized, dimensional Euler equations for acoustic computation can be accurately solved as a set of decoupled first-order wave equations, and that if ordered properly, this system of simple waves has unambiguous, easily implemented boundary conditions, allowing waves of same group speeds to pass through numerical boundaries or comply with wall conditions. Thus, the task of designing a complex multi-dimensional scheme with approximate far-field boundary conditions reduces to the design of higher order schemes for the one-dimensional simple wave equation. A compact finite-difference scheme and a characteristically exact but numerically n(th) order accurate boundary condition are introduced for solving the first order wave equation. Spanning a three-point two-level stencil, this low-dispersion implicit scheme has a third order spatial accuracy when used on nonuniform meshes, fourth order accurate on uniform meshes, and a temporal accuracy of second order due to the choice of trapezoidal integration for algorithmic simplicity. The robustness and accuracy of the scheme are demonstrated through a series of numerical experiments and comparisons with published results. When tested on the one-dimensional wave equation on a uniform grid, this scheme allows a Gaussian wave packet to pass through any finite domain with low numerical dispersion characteristic of a spatially fourth-order scheme and reflections at numerical boundaries maintained below truncation error. On highly stretched and irregular grids, only mild dispersions are found in the solution while solutions by other methods fail or are severely distorted. Yet, this scheme is no more sophisticated to solve or implement than the Crank-Nicolson scheme. This scheme has been tested on four categories of the ICASE/LaRC benchmark problems, which include propagation of acoustic and convective waves in Cartesian and cylindrical domains, reflection of acoustic wave at stationary/moving boundaries, and sound generation by gust-blade interaction.
School Psychology Trainees’ Administration and Scoring Errors on the Woodcock-Johnson IV Tests of Achievement

Sixty-three Woodcock–Johnson IV Tests of Achievement protocols, administered by 26 school psychology trainees, were examined to determine the frequency of examiner errors. Errors were noted on all protocols and ranged from 8 to 150 per administration. Critical (e.g., start, stop, and calculation) errors were noted on roughly 97% of protocols. Wilcoxon signed-rank tests indicated multiple subtests were more prone to both critical and non-critical (e.g., failure to record answers verbatim, failure to record qualitative observations) errors; critical errors were generally more common on subtests with objective scoring criteria (i.e., Written Expression and Spelling) and non-critical errors were more frequently observed on subtests that required the recording of answers verbatim. Based on these findings, we encourage trainers to place increased scrutiny on trainee’s objective scoring performance and on requiring recording responses verbatim. Areas of needed future research studies are also discussed.
Reconstruction of the record of tritium in precipitation in the temperate zone of South America

Tritium, a radioisotope of hydrogen, is an ideal tracer for groundwater and surface dating and tracking since it is part of the water molecule. The knowledge of the history of tritium in precipitation and recharge is the key link for the calculation of groundwater tritium age. However, records of tritium in precipitation are usually sparse and discontinuous, especially in regions like South America, and often need to be reconstructed. To solve this problem, different reconstruction methods of the tritium input function have been analysed and compared. Clustering of Global Network of Isotopes in Precipitation stations by regions and the correlation with the complete and continuous data recorded in Kaitoke (New Zealand) proved to be the most effective approach, having low relative errors and a much more extended coverage in time compared to other interpolation or reference curves methods. Thus, tritium time series for five different regions of the temperate zone of South America were obtained. These curves can be used as representative tritium input curves in future studies for these regions. The results obtained also allow a quick qualitative analysis of groundwater ages in these areas, based on their current or past tritium concentrations. In addition, they contributed to the understanding of the patterns and characteristics of tritium distribution in the atmosphere of the southern sector of South America.
Characterizing temporal and spatial scales of radiatively driven convection in a deep, ice‐free lake

From May to July 2019, an array of moored equipment was deployed in Lake Superior to characterize the spatial and temporal scales of radiatively driven convection (RDC). Previous work suggested that convective plumes have horizontal scales on the order of tens of meters, posing a significant observational challenge. The centerpiece of the deployment was a large, two‐dimensional (2D) array of thermistors that provided resolution on the order of 10 meters in both the vertical and a single horizontal dimension. This was augmented by an acoustic Doppler current meter mooring and a meteorology buoy capable of estimating surface heat and momentum fluxes. Instantaneous temperature variability at a given location is dominated by a lateral background flow advecting strong horizontal temperature gradients. By combining velocity data with temperature data, this fact can be used to examine horizontal structure at centimeter scales, and can produce 2D images of instantaneous temperature distribution on a horizontal surface, revealing multiple patterns of temperature anomaly distribution. The walls of convective structures are very sharp, with horizontal gradients on the order of 1°C m−1; horizontal scales of convective structures themselves are on the order of many tens of meters. Finally, convection is shown to strongly control the vertical distribution of water quality parameters.
Single image deraining using multi‐stage and multi‐scale joint channel coordinate attention fusion network

Rain streaks can seriously degrade the visual quality of an image and are detrimental to subsequent algorithms such as object detection and semantic segmentation. Therefore, removing rain streaks is a very important task. The deraining task has two main limitations: the first is to encode information about rain streaks in different densities and directions, the second is to keep the background details of the image while removing the rain streak. To address these limitations, we propose an effective algorithm, called multi‐stage and multi‐scale joint channel coordinate attention fusion network (MMAFN). We mainly propose a two‐stage network structure, both of which use an encoder‐decoder network to extract features. The first‐stage network extracts coarse features and the second‐stage network integrates the features of the former to further refine features. We design the joint channel coordinate attention block to encode features of rain streaks in different directions and densities. In addition, to better fuse features of different scales and enhance the generalization performance of the network, the inception attention branch block and the multi‐level feature fusion block are designed. Extensive experiments substantiate the superiority of the proposed network and prove that our method outperforms the recent state‐of‐the‐art method. The average PSNR of the five test sets is improved by 0.2dB. On the Test100 test set, the PSNR is increased by 0.93dB at most.
Definitions of Solitude in Everyday Life

What does it mean to be in solitude? Researchers building this nascent field are learning much about the potential affordances of solitude, but lack an agreed-upon definition or set of definitions. Arriving at that meaning is crucial to forming a solid foundation for studies that use both naturalistic and laboratory designs to explore outcomes of solitude. This study identified themes from semi-structured interviews with adults aged 19 to 80 from diverse backgrounds. We concluded that solitude is a state in which the dominant relationship is with the self. If not physically alone, people in solitude are mentally distanced from others and away from active technology-mediated interactions. Complete solitude involves both physical separation and inner focus, but solitude is best defined through a taxonomy that recognizes physical separation and internal focus as independent, sufficient characteristics. An internal focus benefits from (but is not defined by) balancing solitude with social time, quiet, and choice.
ON A DUSTY GAS SHOCK TUBE *

Analytical and numerical methods were used to investigate the flow induced by a shock wave in a shock tube channel containing air laden with suspended small solid particles. Exact results are given for the frozen and equilibrium shock wave properties as a function of the diaphragm‐pressure ratio and shock wave Mach numbers. The driver contained air at high pressure. A modified random choice method, together with an operator‐splitting technique, shows clearly the decay both of a discontinuous frozen shock wave and of a contact discontinuity and the formation both of a stationary shock structure and of an effective contact front of finite thickness. The effects of particle diameter, particle‐number density, and diaphragm‐pressure ratio on the transitional behavior of the flow are investigated in detail. The alteration of the flow properties owing to the presence of particles is discussed thoroughly and compared with classical shock tube flows.
In silico studies of viral protein inhibitors of Marburg virus using phytochemicals from Andrographis paniculata

The Marburg virus is a causative agent of Marburg hemorrhagic fever, which was discovered in Marburg, Germany, in 1967. It is a highly contagious and fatal disease transmitted by body fluids. The reservoir host is African fruit bats. Currently, there is no vaccine available to control this disease. Medicinal plants possess many phytochemicals of great therapeutic value. Many have antiviral properties and have been identified as promising drug molecules against various viral diseases proven with an in silico approach. The current research uses the in silico approach to identify the phyto-derived drugs from Andrographis paniculata to treat the Marburg virus. Twenty-four bioactive molecules from the A. paniculata plant were investigated against the targets VP35 and VP40 of Marburg viral proteins using the AutoDock Vina 1.1. 2 tool. Out of 24 compounds, Andrographidine C, Andrographidine A, Andrographolactone, and 7-O-methylwogonin showed best docking scores for the target VP40 dimer while Bisandrographolide A, Luteolin Andrographolide, and Andrographiside showed best docking scores with VP35 protein. To determine the druglikeness, pharmacokinetic and pharmacodynamic properties and toxicity for each target’s highest docking score compound was assessed using the Swiss absorption, distribution, metabolism, and excretion (ADME) and pkCSM tool. Andrographidine C and Andrographolide performed well in all the parameters of ADME and toxicity. These compounds are recommended as effective inhibitors of VP35 and VP40 of Marburg virus and potential antiviral drugs to treat the hemorrhagic disease. Furthermore, in vitro and in vivo studies can be used to examine the effectiveness and mode of action against the proteins of the Marburg virus.

EFFECTS OF INQUIRY-BASED CHEMISTRY EXPERIMENTATION ON STUDENTS’ ATTITUDES TOWARDS THE TEACHING AND LEARNING OF CHEMISTRY

Students' attitude towards a subject is a key indicator of academic performance, therefore its enhancement is imperative for academic success. A sample of 328 grade eleven students was selected using cluster random sampling. Two different study groups; the experimental and control groups, were composed and exposed to the guided inquiry and demonstration methods of teaching chemistry experiments respectively. The Non-equivalent control group research design was employed with instruction lasting six weeks. Data on pre-test and post-test attitudes were collected using a 25-item attitude towards teaching and learning chemistry through experiment survey. Comparisons of mean attitude scores were made between the experimental and control groups, and between the pre-test and post-test for each group. The Mann-Whitney U test analyses indicated a higher mean attitude score for the control group. However, the difference in the mean scores was not statistically significant. The Wilcoxon Signed-Rank test analyses indicated statistically significant differences between the pre-test and post-test attitude mean scores for both independent groups. These outcomes show that both methods of teaching chemistry through experiments enhance students' attitudes to essentially the same extent. These findings imply that Liberian teachers can enhance students' attitudes through demonstrations. Keywords: chemistry experiments, demonstration, guided inquiry, non-equivalent control group, students’ attitude
Stable and Random Motions in Dynamical Systems: With Special Emphasis on Celestial Mechanics.

One of the world’s leading mathematicians, Jurgen Moser developed theories in celestial mechanics and many other aspects of mathematics. He is most renowned for his work on the Kolmogorov-Arnold-Moser theorem. Stable and Random Motions in Dynamical Systems examines how to decide when a dynamical system has stable or unstable behavior. The book was motivated by the stability problem in celestial mechanics: can we prove that the solar system is stable? Moser explains the historical roots of the question, makes it precise, and sets up the mathematical questions that the rest of the book addresses: the Kolmogorov-Arnold-Moser theorem, dealing with quasi-periodic motions, and the Smale-Birkhoff theorem, connecting dynamical systems with Bernoulli processes. These are the “stable” and “random” aspects to which the title alludes. The book resulted from the inaugural Hermann Weyl Lectures at the Institute for Advanced Study in . Originally published in the Annals of Mathematics Studies series, the book was reissued in the Princeton Landmarks in Mathematics series in . In the foreword to this most recent edition, Princeton mathematician Philip J. Holmes wrote, “After almost thirty years, Moser’s lectures are still one of the best entrees to the fascinating worlds of order and chaos in dynamics. ”
MRI pattern in acute optic neuritis: Comparing multiple sclerosis, NMO and MOGAD

Background Several MRI findings of optic neuritis (ON) have been described and correlated with specific underlying etiologies. Specifically, optic nerve enhancement is considered an accurate biomarker of acute ON. Objective To identify differences in MRI patterns of optic nerve enhancement in certain demyelinating etiologies presenting with acute ON. Methods Retrospective analysis of enhancement patterns on fat-suppressed T1-weighted images from patients presenting clinical and radiological acute ON, treated at our institution between January 2014 and June 2022. Location and extension of enhancing optic nerve segments, as well as presence of perineural enhancement were evaluated in three predetermined demyelinating conditions. Fisher’s exact test and chi2 were calculated. Results Fifty-six subjects met eligibility criteria. Mean age was 31 years (range 6–79) and 70% were females. Thirty-four (61%) patients were diagnosed with multiple sclerosis (MS), 8 (14%) with neuromyelitis optica (NMO), and 14 (25%) with anti-myelin oligodendrocyte glycoprotein disease (MOGAD). Bilateral involvement was more frequent in MOGAD, compared to MS and NMO (43 vs 3% and 12.5% respectively, p = 0.002). MS patients showed shorter optic nerve involvement, whereas MOGAD showed more extensive lesions (p = 0.006). Site of involvement was intraorbital in 63% MS, 89% NMO, 90% MOGAD (p = 0.051) and canalicular in 43% MS, 33% NMO and 75% MOGAD (p = 0.039). Intracranial or chiasmatic involvement and presence of perineural enhancement were not statistically different between entities. Conclusion In the setting of acute ON, patients presenting MOGAD were more likely to show bilateral, longitudinally extended and anterior (intraorbital and canalicular) optic nerve involvement compared to patients with MS or NMO.
