THE LEVEL OF PHYSICAL ACTIVITY OF CHILDREN IN KINDERGARTEN IN THE LIGHT OF SELECTED INDIVIDUAL FACTORS

Taking into account the psychophysical development of a young person, a child in particular, attention should be paid to forming certain habits related to physical activity, health, nutrition, hygiene, and aesthetics during the preschool period as such habits will be of utmost importance in his/ her adult life. Physical activity of children affects various health parameters both today and in the future. Specialists draw attention to the correlation between physical activity and the development of the musculoskeletal system, body posture, the nervous, respiratory and vegetative systems. The lack of physical activity may result in cardiovascular diseases or obesity. These are just some of the reasons for which people need physical activity in their lives. Bearing in mind the lack of research on this issue, it was decided to conduct research on the physical activity of children (210 students) aged 4-6 attending selected kindergartens located in the town of Biała Podlaska, Poland. The level of physical activity of children was measured with the use of special devices, so called actigraph units (accelerometers in Polish). Due to a small size of this wrist-watch-like device, movements of children or their participation in games and different forms of activities in kindergarten were not hampered. On the basis of the collected data, statistical analysis was performed. Non-parametric statistical tests were used in order to identify the relationship between variables of the physical activity level and sex, age and weight of a child. Data analysis revealed statistically significant differences between the level of physical activity and some personal characteristics. The research conclusions, which will be helpful in providing effective education in the field of physical activity, were made available to kindergartens.
Insight into the Microenvironments of the Metal–Ionic Liquid Interface during Electrochemical CO2 Reduction

Recently, many experimental and theoretical efforts are being intensified to develop high-performance catalysts for electrochemical CO2 conversion. Beyond the catalyst material screening, it is also critical to optimize the surrounding reaction medium. From vast experiments, inclusion of room-temperature ionic liquid (RTIL) in the electrolyte is found to be beneficial for CO2 conversion; however, there is no unified picture of the role of RTIL, prohibiting further optimization of the reaction medium. Using a state-of-the-art multiscale simulation, we here unveil the atomic origin of the catalytic promotion effect of RTIL during CO2 conversion. Unlike the conventional belief, which assumes a specific intermolecular coordination by the RTIL component, we find that the promotion effect is collectively manifested by tuning the reaction microenvironment. This mechanism suggests the critical importance of the bulk properties (e.g., resistance, gas solubility and diffusivity, viscosity, etc.) over the detailed c.
Développement d'une méthode électrophorétique de séparation de l'uranium, du plutonium et des lanthanides et couplage avec un ICPMS-MC pour l'acquisition de rapports isotopiques

La caracterisation isotopique des elements presents dans les combustibles nucleaires irradies est d'une importance majeure pour la qualification et la validation des codes de calculs neutroniques ainsi que la gestion des dechets nucleaires. Le protocole conventionnel pour l'analyse de ces echantillons necessite plusieurs etapes de separation par chromatographie liquide. L'uranium (U), le plutonium (Pu) et une fraction contenant les produits de fission et les actinides mineurs, sont separes par chromatographie sur resine echangeuse d'ions puis les fractions purifiees d'U et de Pu sont analysees par spectrometrie de masse. L'objectif de cette these consiste a etudier et developper un protocole analytique applicable sur des echantillons de type combustibles irradies et employant une technique separative transposable sur plateforme miniaturisee qui devra pouvoir etre couplee a un spectrometre de masse a source plasma et a systeme multicollection (ICPMS-MC) afin de realiser en ligne l'analyse isotopique et elementaire des elements presents dans le combustible irradie. Une methode de separation de l'U, du thorium (Th) et des lanthanides par electrophorese capillaire (EC) avec preconcentration de l'echantillon a ete developpee en utilisant le Th(IV) comme analogue chimique du Pu(IV). L'electrolyte de separation se compose d'acide acetique 0,25M comme complexant ainsi que de sel d'ammonium 0,1M, pour ajuster la force ionique et permettre la preconcentration. Le montage d'EC a ete adapte afin d'etre integre en boite a gants et couple a un ICPMS-MC. La separation de l'Am de l'U et du Pu a ete realisee sur quelques nL d'une solution de combustible irradie.
Comparative Evaluation of Different Needle Gauge of Needle for Spinal Anesthesia in Cesarean Section for Post-Operative Complication

Background: Post dural Pucture headache (PDPH) Particularly Following Caesarean Section is a well-known iatrogenic complication of spinal anaesthesia mostly occours due to loss of cerebrospinal fluid (CSF) during the procedure. Aims and Objectives: The study was planned to assess comparative superiority of 27 gauze spinal needle over 25 gauze spinal needle in caesarean section for reduction of PDPH. Subjects and Methods: The study was conducted on hundred full term primi-parous women aged within 18-36 years undergoing elective Caesarean Section were selected. They were divided into two groups, receive spinal anaesthesia with 25 gauze and 27 gauze spinal needle. Results: The overall incidence of PDPH of 100 CS patients was 17% and significantly higher incidence is noticed in-group A than group B (26% vs 10%, p <0.05>). Attempt required to attain CSF is higher in group B and finer needle takes significantly more time to collect CSF (P<.001). Mean Duration for CSF Collection was 35.08±13.43 seconds (group A) and 81.12±16.71 seconds (groups B). Conclusion: Use of 27G spinal needle will be a good choice for reduction of PDPH.
Understanding the structure of water, ice, and aqueous solutions next to solid surfaces

The phase change of water into ice on solid surfaces has significant impact on infrastructure and human activity. In this thesis, we have set out to understand the structure of water as it is systematically cooled to form ice next to solid surfaces. We have coupled a novel heating and cooling device with surface sensitive sum frequency generation spectroscopy (SFG) to observe molecularly how water interacts with solid surfaces as temperature is decreased. This we believe can lead to a better understanding of how to delay ice formation or reduce ice adhesion to surfaces. SFG (used mainly in the total internal reflection geometry) is a nonlinear optical technique which detects the orientation and molecular arrangement at surfaces and interfaces. We used sapphire and mica as model surfaces for our experiments. In the first part of this research, we have performed experiments on a neutral sapphire surface. We have observed that the SFG signal intensity increased considerably when ice was formed. This shows that the water molecules in ice interact strongly with each other and with the solid surface. When temperature was further decreased, the ice peak intensity increased, indicating the increased coherence length of the water molecules in ice. SFG spectra of ice during heating show gradual signal attenuation. Contrary to ice surfaces, no interface premelting of ice was observed during the heating cycle.

Rapid communication Protonation effect on drug affinity

Pharmacologic ligand–macromolecule interactions are commonly characterized by affinity (dissociation) constants such as Kd or Ki without regard to the protonation effect of the buffer used in the measurement. The protonation effect is demonstrated here using isothermal titration microcalorimetry measurements of the competitive inhibitor binding of cytidine 2V-monophosphate (2V-CMP) to RNase-A as a model system in buffers of different ionization DHbuffer. The results demonstrate the importance of protonation in measures of affinity. D 2003 Elsevier B.V. All rights reserved.
Design of dye-sensitized solar cells using TiO2 pastes with different secondary particles sizes

Abstract. Titanium dioxide (TiO2) pastes containing secondary particle with varying sizes are prepared by modulating the dispersion time of the dispersion liquid. The appearances, mesoscopic structures, and transmission spectra of the TiO2 layers constructed using these pastes depend on the sizes of the secondary particles. However, the dye-sensitized solar cells (DSSCs) constructed using different pastes show similar photoelectric conversion performances despite the different mesoscopic structures and transmission properties of the TiO2 layers. The DSSCs based on the experimental TiO2 pastes show lower photoelectric conversion efficiencies compared with the DSSC constructed using a commercially available reference paste. These results suggest that the primary TiO2 particles have a greater influence on the photoelectric conversion performance of the DSSC than the secondary particles. The incident photon-to-current conversion efficiency spectra of the DSSCs based on the TiO2 pastes exhibit a slight dependence on wavelength. Thus, it is possible that minor light-scattering effects resulting from the mesoscopic structure of TiO2 occur in the DSSCs constructed using the pastes. These results indicate that TiO2 pastes with fixed primary particle sizes but different secondary particle sizes can be used to change the appearance or design of DSSCs without affecting their photoelectric conversion performance.
Doctors' Stories: The Narrative Structure of Medical Knowledge

A patient's job is to tell the physician what hurts, and the physician's job is to fix it. But how does the physician know what is wrong? What becomes of the patient's story when the patient becomes a case? Addressing readers on both sides of the patient-physician encounter, Kathryn Hunter looks at medicine as an art that relies heavily on telling and interpreting a story--the patient's story of illness and its symptoms.
Ceftizoxime, cefdinir, cefditoren, cefpodoxime, ceftibuten, cefsulodin, and cefpiramide

Extended-spectrum, or third-generation cephalosporins, were developed after the first- and second-generation drugs. Due to their prominence, ceftriaxone (see Chapter 27, Ceftriaxone), cefotaxime (see Chapter 26, Cefotaxime), and ceftazidime (see Chapter 30, Ceftazidime and ceftazidime-avibactam) are discussed in detail in their own chapters. However, other thirdgeneration cephalosporins, such as ceftizoxime, cefdinir, cefditoren, cefpodoxime, ceftibuten, cefsulodin, and cefpiramide, are available in only certain countries or are seldom if ever used in contemporary practice. Description of these antibiotics is therefore limited, with the exception of ceftizoxime (as a representative of a parenterally administered third-generation cephalosporin) and cefpodoxime (as a representative of an orally administered third-generation cephalosporin).
Ribavirin Therapy of Adult Respiratory Syncytial Virus Pneumonitis

Respiratory syncytial virus is a common respiratory tract pathogen in infants. Pulmonary infection in adult and elderly populations can occur with severe and even fatal pneumonitis having been reported in several recent out-breaks. We present a previously healthy adult patient who developed respiratory syncytial virus pneumonia severe enough to require mechanical ventilation. Antiviral therapy with aerosolized ribavirin was successfully undertaken and the patient recovered completely. Respiratory syncytial virus infection should be considered in the differential diagnosis of atypical adult pneumonias. Aerosolized ribavirin therapy may be beneficial in treatment.

A flexible and highly sensitive pressure sensor based on elastic carbon foam

In this paper, we fabricate a flexible elastic carbon foam (ECF)-based pressure sensor by direct carbonization of melamine foams (MF) at 800 °C without using any metal catalyst. The carbonized ECF is composed of a unique 3D interconnected concave triangular carbon network with a fraction of cracked carbon microfibers, and displays abundant micro and meso-porosity. We select the ECF as a sensing material due to its conductive and elastic features, and make a piezoresistive sensor with ultrahigh sensitivity (100.29 kPa−1) and reproducible sensing (11 000 cycles) characteristics. Moreover, the pressure sensor is able to distinguish a large pressure range from as low as 3 Pa to 10 kPa. The cheap raw materials, simple fabrication process and satisfactory performance of the pressure sensor make it a promising device for electronic monitoring systems in industrial detection, human motion monitoring and so on.
Understanding the alkali – Germanium interaction in the ternary Zintl phase Li18Na2Ge17: First-principles study

The Zintl ternary phase, Li18Na2Ge17, have been synthesized typically from a very electropositive metals (Ge) and more electronegative main group metals Na and Li. We attempted to understand its electronic structure and the contribution of electropositive and electronegative groups by employing first-principles calculations. Li18Na2Ge17 is a semiconductor with a narrower and indirect band gap about 0.254 eV. Charge density difference distribution supplemented by Bader population were reported to characterize the bonding. As a ternary Zintl, Li18Na2Ge17 is obeying to the Zintl–Klemm concept, where an electron transfer from the alkali metal atoms (Li, Na) to the clusters (Ge17) is demonstrated.

Estimation of sensitivity coefficient based on lasso-type penalized linear regression

ABSTRACT We proposed the penalized regression ‘adaptive smooth-lasso’ for the estimation of sensitivity coefficients of the neutronics parameters. The proposed method utilizes the variation of the microscopic cross-sections and the neutronics parameters obtained by random sampling. The weighted penalty term of the proposed method is more appropriate for the estimation of the sensitivity of neutronics parameters to the microscopic cross-section than that of the conventional methods. In a numerical verification calculation, sensitivity coefficients of k eff of an accelerator-driven system are estimated using the proposed method, the conventional penalized regression, and the direct method. Comparison of these results indicates that the proposed method is superior to the conventional penalized linear regression from the viewpoint of reproduction of the reference sensitivity coefficients obtained by the direct method. Through the verification calculations, the proposed method can be a candidate for a practical method to estimate the sensitivity coefficients with low calculation cost.
A review of scanning probe microscopy investigations of liposome-DNA complexes.

Liposome-DNA complexes are one of the most promising systems for the protection and delivery of nucleic acids to combat neoplastic, viral, and genetic diseases. In addition, they are being used as models in the elucidation of many biological phenomena such as viral infection and transduction. In order to understand these phenomena and to realize the mechanism of nucleic acid transfer by liposome-DNA complexes, studies at the molecular level are required. To this end, scanning probe microscopy (SPM) is increasingly being used in the characterization of lipid layers, lipid aggregates, liposomes, and their complexes with nucleic acid molecules. The most attractive attributes of SPM are the potential to image samples with subnanometer spatial resolution under physiological conditions and provide information on their physical and mechanical properties. This review describes the application of scanning tunneling microscopy and atomic force microscopy, the two most commonly applied SPM techniques, in the charact.
Modelling heterogeneous phosphate sorption kinetics on iron oxyhydroxides and soil with a continuous distribution approach

The kinetics of orthophosphate (PO4) sorption in soil has far reaching consequences on its long‐term fate. Traditionally, a distinction is made between fast, reversible adsorption and slow fixation. The kinetics are commonly described by compartmental models (CMs) assuming kinetically distinct homogeneous pools (e.g. a rapid‐ and slow‐sorbing pool), with phenomenological equations or with complex diffusion‐based models. Alternatively, this process can be described by assuming frequency distributions of both adsorption and desorption rate constants and, thereby, enabling better description of experimental data with fewer adjustable parameters. Here, we developed such a rate constant distribution (RCD) model and compared it with CMs and other commonly used rate equations. Batch 33PO4 sorption was measured in agitated suspensions between 2 minutes and 20 days after spiking in 13 contrasting types of soil and two iron oxyhydroxides. Overall, the RCD model, with three adjustable parameters, describes the data better than the other models tested. The so‐called slow reactions, denoted as the factor change in soluble 33PO4 between 1 and 20 days after spiking, were described better by the RCD model and ranged from 1.0 (i.e. no change) to 6.9. The extent of slow reactions increased with the increase in the fraction of poorly crystalline iron in the soil (r = 0.69; P = 0.0088). Equilibrium was elusive up to 20 days for PO4 sorption on ferrihydrite and on soil samples with a large fraction of poorly crystalline iron oxyhydroxides. The RCD model code is available as freeware from the first author.
The delta-like ligand 4-notch signaling inhibits tumor angiogenesis but promotes tumor growth in primary glioblastoma: An immunohistochemical study

Background: Delta-like ligand 4 (DLL4) is a key Notch ligand implicated in tumor angiogenesis. However, previous studies have shown that the DLL4-Notch signaling inhibits tumor angiogenesis but promotes tumor progression in primary glioblastoma. The underlying mechanism remains unknown. Methods: Tumor tissues from 70 patients with primary glioblastoma were analyzed by immunohistochemistry for the expression of DLL4, microvessel density (MVD), and Ki67 labeling index. The degree of tumor contrast enhancement (DTCE) on preoperative magnetic resonance imaging was also evaluated. The effect on prognosis was assessed based on Kaplan–Meier survival and Cox proportional hazard models. Results: Results showed that the DTCE was negatively correlated with DLL4 but positively correlated with MVD (r = −0.260, 0.593, P < 0.05). The Ki67 labeling index was shown to be positively correlated with both DLL4 and MVD (r = 0.346, 0.346, P < 0.05). Univariate analysis indicated a significant correlation of high DLL4 and Ki67 labeling index expression with shorter progression-free survival (PFS) and overall survival (OS) (P < 0.05). Multivariate analysis confirmed high DLL4 and MVD expression as unfavorable prognostic indicators for PFS and OS (P < 0.05), and the hazard ratio of DLL4 was higher than MVD for both PFS and OS (P < 0.05). Conclusion: We conclude that the DLL4-Notch signaling improves tumor vascular function and contributes to the survival of malignant cells, resulting in less MVD but more tumor progression in primary glioblastoma.
Keller-Box Scheme for Casson Nanofluid Flow over Nonlinear Inclined Surface with Soret and Dufour Effects

In this article, Casson Nanofluid boundary layer flow over non-straight slanted extending surface with Soret and Dufour impact scrutinized. Model used in this study is based on Buongiorno model for the thermal efficiencies of the fluid flows in the existence of Brownian motions and thermophoresis properties. The nonlinear problem for Casson Nanofluid flow over inclined channel is modeled to think about the heat and mass exchange phenomenon by considering portent flow parameters to intensified boundary layers. The overseeing nonlinear partial differential equations are changed to nonlinear ordinary differential equations and afterward illustrated numerically by methods for the Keller-Box conspire. A comparison of the established results in the lack of the incorporated effects is performed with the available outcomes of Khan and Pop [1] and recognized in a nice settlement. Numerical and graphical results are also presented in tables and graphs.
