Field: Social Sciences (Social Sciences)

Abstract This study aims to determine the effectiveness of blended learning towards the improvement of pre-service teacher TPaCK (Technological Pedagogical Content Knowledge) in developing multimedia learning mathematics in elementary schools. The type of this research is a quasi-experimental design. The research method used is a non-equivalent control group design. The population of this study was the 6th-semester students of the 2018/2019 academic year of the PGSD UAD study program of 315 students grouped in 7 classes. The sample used was an experimental class of the class controller drawn at random. The method of collecting data uses observations in multimedia learning mathematics that have been developed by pre-service elementary school teachers. The research instrument used the TPaCK assessment sheet that had been taken expert validation. The results of the study showed that at a significance level of 5% blended learning was effective in increasing the TPaCK of pre-service teachers in developing multimedia learning mathematics in elementary schools.
Theory and optimization of the parameters of a polarization method for the measurement of weak absorption in optical materials

Field: Physics and Astronomy (Physical Sciences)

A theoretical analysis is made of a polarization calorimetric method for the determination of weak absorption in optical materials. Several variants of the method are considered and the optimal conditions for its application are identified. The sensitivity of the method is ~1 dB/km for a sample 1 cm thick. It is shown that the method can be used to determine absorption in optically anisotropic materials.
Indoor Visible Light Positioning Based on Image Denoising and Phase Difference Vector Fingerprint

Field: Computer Science (Physical Sciences)

Visible light positioning (VLP) technology has become a promising technology in the field of indoor positioning benefits from its greenness and low cost. However, the traditional fingerprint construction scheme in radio frequency cannot be effectively applied in the VLP system and the positioning accuracy of the fingerprint-based VLP system suffers from its specific propagation channel noise. Therefore, a novel fingerprint construction method based on phase difference vector (PDV) and fingerprint denoising network (FDNet) is proposed to improve the stability and positioning accuracy of the VLP system. Specifically, the arrival phase difference information is considered to construct a fingerprint image, and the improved denoising network is designed to obtain relatively high signal-to-noise ratio fingerprint information. Moreover, the positioning is achieved by mapping the constructed fingerprint database to location information through a back propagation (BP) network. The simulation results show that the proposed PDV-based FDNet positioning method achieves an average positioning accuracy of 1. 43cm, which outperforms the existing benchmark methods.
Enhancement and bioavailability of phenolic content in Kappaphycus alvarezii through solid substrate fermentation

Field: Agricultural and Biological Sciences (Life Sciences)

Known as carrageenan, Kappaphycus alvarezii is a popular species of red edible seaweed which is mainly cultivated for its hydrocolloids. K. alvarezii is a good source of phenolics which are considered to be natural antioxidants that promote myriads of health benefits. Extraction of phenolic compounds using conventional solvent extraction may result in hazards and toxicological effect and low yield of bound phenolics. Therefore, this study was conducted to increase the release of bound phenolics through solid substrate fermentation. In the present study, three different varieties of K. alvarezii were fermented with Aspergillus oryzae through solid substrate fermentation (SSF) at 30 ℃ for 2 to 6 days. The changes of total phenolic content and antioxidant activity due to the effects of SSF were investigated. Results obtained revealed that the highest total phenolic content for green (10.022 mg GAE/g) and purple (4.037 mg GAE/g) varieties of K.alvarezii were on the fourth day of fermentation while for yellow (4.479 mg GAE/g) variety was on the sixth day of fermentation. A remarkable enhancement of antioxidant activity was discovered through DPPH radical scavenging activity on the fourth day of fermentation for all varieties of K. alvarezii tested. Total phenolic content also showed a significant correlation with antioxidant activity of fermented seaweed. Cellulase, xylanase, and β-glucosidase enzymes produced by A.oryzae during SSF were also investigated to see the relationship with the release of phenolic compounds after fermentation. The highest cellulase activity was observed on the fourth day of fermentation. The similar observation was also found for xylanase enzyme in yellow and purple varieties of K. alvarezii , except for green variety where the highest xylanase activity was on the sixth day of fermentation. The maximum β-glucosidase activity in yellow and green varieties was observed on the fourth day of fermentation while purple variety exhibited the maximum β-glucosidase activity on the sixth day. There are positive correlation between the enzymes studied and the polyphenols content in all varieties of K. alvarezii . This study demonstrated that fermented K. alvarezii contained more phenolic content compared to non-fermented seaweed.
[Surgical technique in ski thumb injury].

Field: Medicine (Health Sciences)

The skier's-thumb, an instability of the ulnar collateral ligament (UCL) of the first metacarpo-phalangeal joint is one of the most common hand injuries in alpine skiing. In over 60% of our cases the ligament is ruptured, mostly near or at its distal insertion at the base of the first metaphalanx. Also a bony avulsion of the UCL at its distal insertion is not uncommon. A significant instability or a bony avulsion of the UCL with dislocation of the fragments is an indication for open reconstruction and stabilization. Good experience has been gained with a fish hook pull-out-wire technique. We describe the approach and the reconstruction technique.
Modele polskiej polityki pamięci. Obrazy wojny o Lwów w listopadzie 1918 roku w polskich periodykach polityczno-społecznych w miesiącu stulecia niepodległości Polski

Field: Social Sciences (Social Sciences)

This article contains a comparative analysis of presentations in selected Polish periodicals in November 2018 of the war between Poland and the Western Ukrainian People’s Republic over Lviv and Eastern Galicia in the years 1918–1919. In an analysis of the media discourse the author takes into account factographic, axiological, teleological, ideological, and political dimensions. He distinguishes five conventions for the presentation of the events: national-dramatic, national-heroic, martyrological-defamatory, tragic, and tragi-comical. He argues that not all have been represented in the different models of memory policy functioning in the public debate in Poland under the governments of the Law and Justice party (2015–2019). He considers that there have been four such models: the nationalist-Catholic, conservative-nationalist, universalist-patriotic, and self-critical. He argues that the rightist political party (Law and Justice) has long aligned itself with the conservative-nationalist model, while centrist groups, and especially the leftist group, do not attach great importance to memory policy. The author points to the danger resulting from neglect of historical issues in the Polish media.
Menstrual Cycle Changes in Mate Preferences for Cues Associated with Genetic Quality: The Moderating Role of Mate Value

Field: Psychology (Social Sciences)

The purpose of the study was to explore the influence of mate value and fertility status on women's implicit and explicit preferences for male traits associated with genetic quality. It was hypothesized that a woman low in mate value would experience greater fluctuation across her menstrual cycle in her preferences for characteristics associated with genetic quality than a woman high in mate value. Specifically, a low mate value woman during the non-fertile part of the cycle would experience a reduction in a desire for traits associated with health and reproductive success. To test the hypothesis, the college age female participants completed two measures of mate value and a self-report measure designed to gauge fertility status. Then the participants performed an Implicit Associations Test (IAT) designed to measure implicit associations with a male trait related to genetic quality and a questionnaire designed to measure their explicit responses to the same trait. As predicted, mate value moderated the relationship between fertility status and implicit preferences.
Microring Distributed Sensors Using Electron Cloud Generated by Four-point Probe Sagnac Interferometer

Field: Engineering (Physical Sciences)

A micro Sagnac interferometer integration is proposed for electron cloud distributed sensors. The Sagnac interferometer consists of four microring probes integrated into a Sagnac loop. Each of the microring probes is embedded with the silver bars to form the plasmonic wave oscillation. At the center microrings, electrons are trapped and oscillated by the whispering gallery modes (WGMs), where the plasmonic antennas are established and applied for wireless fidelity (WiFi) and light fidelity (LiFi) transmissions for distributed sensors. The antenna gains are 2.59dB, 0.93dB, 1.75dB, and 1.16dB respectively for the four antennas formed at the center microrings. The polarized light of 1.50µm wavelength is fed into the interferometer input, which is polarized randomly into upstream and downstream directions. The polarization components can be obtained by the space-time modulation control. By controlling the electron cloud spin orientation, the space-time projection can be applied, and the ultra-high measurement resolution can be obtained in terms of fast switching time (change in phase). In manipulation, the applied stimuli are substituted by the change in input source power. The light input power variation causes a change in electron cloud density. Similarly, when the electron cloud is excited by the microscopic medium, which can be employed as the microscopic sensors. The WGM sensors have sensitivities of 1.35µm-2, 0.90µm-2, 0.97µm-2 and, 0.81µm-2, respectively. The WGMs behave as a four-point probe for the electron cloud distributed sensors, where the electron cloud sensitivities of 2.31 prads-1mm3 (electrons)-1, 2.27prads-1mm3 (electrons)-1, 2.22 prads-1mm3(electrons)-1, 2.38prads-1mm3(electrons)-1 are respectively obtained.
Dominance of ordinal sums of the Łukasiewicz and the product triangular norm

Field: Mathematics (Physical Sciences)

In this paper we provide a simple characterization of the dominance in two classes of continuous triangular norms.In particular, we solve the dominance of (i) ordinal sum t-norms that use the Łukasiewicz t-norm as the only summand operation and (ii) ordinal sum t-norms that use the product t-norm as the only summand operation.In both cases, the dominance relation is characterized by a simple property of the idempotent elements of the dominating t-norm.We also introduce the notion of the axis of a conjunctor and, as a side result, we characterize dominance of continuous conjunctors in terms of their axes.
Endogenously labeled low density lipoprotein triglyceride and apoprotein B kinetics.

Field: Medicine (Health Sciences)

The kinetics of endogenously labeled low density lipoprotein (LDL) triglycerides (TG) and apoprotein B (apoB) have been studied in four normal and in four hyperlipemic subjects using double tracers. Analysis of the data suggests that most LDL triglycerides turn over about 10 times faster than apoB (0.003/min vs. 0.0003/min) and that about 10% of the LDL particles contain most of the TG found with LDL. It is not possible to determine from the analysis whether each new LDL particle arrives with the excess TG or whether only a subpopulation of particles contains most of the TG. The kinetic analysis further suggests that triglyceride-rich LDL particles do not exchange with an extraplasma compartment as most LDL particles do, and thus, they behave more like very low density lipoprotein particles. A compartmental model accounting for both the LDL-TG and LDL-apoB kinetics is proposed.
Anti-HSP70 Autoantibody Formation by B-1 Cells inToxoplasma gondii-Infected Mice

Field: Immunology and Microbiology (Life Sciences)

ABSTRACT Formation of anti- Toxoplasma gondii HSP70 (TgHSP70) antibody cross-reactive to mouse HSP70 (mHSP70) was observed in the sera of BALB/c (a resistant strain) and C57BL/6 (B6; a susceptible strain) mice after peroral infection with T. gondii cysts of the Fukaya strain. The levels of anti-mHSP70 immunoglobulin G (IgG) autoantibody production in B6 mice were higher than those in BALB/c mice. The isotype and subclass of IgG of anti-TgHSP70 monoclonal antibodies cross-reactive to mHSP70 were μ and γ3. Anti-mHSP70 autoantibody in T. gondii -infected BALB/c and B6 mice was shown to be produced by the CD5 + subset of B cells (B-1a cells) but not by conventional B cells (B-2 cells). The epitopes recognized by anti-mHSP70 autoantibody were located primarily in the C-terminal fragment of mHSP70.

Elapsed Time Between the First Symptoms of Breast Cancer and Medical Help-Seeking Behavior and the Affecting Factors

Field: Health Professions (Health Sciences)

Background: Many studies have determined that the time between women’s realization of first symptoms and seeking help from a healthcare professional is more than 1 month. The situation is defined as delay in medical help-seeking behavior (MHSB). Objective: The purpose of this study was to determine the time elapsed between the first symptoms of breast cancer and MHSB, as well as the factors contributing to the delay. Methods: In this descriptive study, the data were collected from 132 patients who received a diagnosis of breast cancer and are receiving treatment in the Oncology Clinic of Akdeniz University Hospital. The questionnaire used in the study was structured in 3 parts: sociodemographic characteristics, breast cancer history/screening behaviors, and psychological factors affecting MHSB. The elapsed time between patients’ first symptoms and MHSB was classified into “normal” when it was less than 1 month, “delay” when it was between 1 and 3 months, “long-term delay” when it was more than 3 months, and “very serious delay” when it was more than 6 months. Results: A total of 59.8% were classified as normal, 16.7% as delayed, 5.3% as a long-term delay, and 18.2% as a very serious delay after first symptoms. The delay in MHSB time was affected 18.55 times by “not caring/minding,” 10.73 times by “fear,” 7.13 times by “having more important problems,” and 4.23 times by “realization of first symptoms” by themselves. Conclusion: Psychological factors were the most important determinants in delay. The MHSB time was less if those first realizing the symptoms were healthcare professionals. Implications for Practice: Healthcare professionals should direct women to screenings and train them to interpret symptoms correctly.
Noble gases anomalies in terrestrial ores and meteorites

Field: Earth and Planetary Sciences (Physical Sciences)

Analyses of the content and isotopic composition of xenon and krypton in terrestiral ores containing tellurium, selenium or iodine res ulted in the following conclusions: 1. The double beta-decay half-life for 130Te is 2.51 x 1021 years from analysis of tellurobismuthite from Boliden, Sweden and 2.83 x 1021 years from analysis of tellurides from Kalgoorlie, Australia. 2. The ratio of the double beta-decay half-life of 128Te relative to that of 130Te is > 108 and> 293 for Boliden tellurobismuthite and Kalgoorlie tellurides, respecti vely. 3. Selenium minerals and tellurium ores containing selenium exhibit 82Kr excess attributed to the double beta-decay of 82se. Preliminary half -life value for this decay is (2-4)1020 years. 4. The formation of excesses of 129xe and 13lxe in tellurium ores and excess 83Kr in selenium ores result from nuclear reactions on tellurium and selenium, respectively. 5. The excess 129xe in iodyrite (silver iodide) is from the in situ decay of 129r incorporated in the ore during its formation. From the observed isotopic composition of xenon, it is calculated that prior to the nuclear age, the equilibrium ratio of 129r;l27r was between 2.2 x 10-15 and 3.3 x 10-15. 6. Measurements of the 130xe, formed from the decay of 13 OTe, and the tellurium content allow the age determination of hydrothermal deposits of tellurium by the 130Te-130xe dating method. The ages of three telluride samples obtained by this new dating technique agree with geologic age estimates. lV Application of the neutron irradiation method of 129r_l29xe dating to chondrules and matrix of Bjurbole meteorite reveal the following: 1. The 129r jl2 7 ratios incorporated in the Bj urbole chondrules and matrix are identical thereby indicating that these fractions are contemporaneous within ± 1. 5 x 106 years. 2. The method of 129r_l29xe age determination by the neutron irradiation method is dependent on the intensity of the neutron flux. The release pattern of iodinecorrelated 129xe is altered for all extraction temperatures by the use of high neutron flux. The relative fission yields from the spontaneous fission of 252cf for krypton and xenon isotopes are 83Kr :84Kr :85Kr :86Kr )3l:Xe )32Xe: 134xe)36xe = 0.010:0.017:0 0049:0.032:0.35:0.52:0.92::1.000. A comparison of these results with the spontaneous fission yields of other actinides suggests that the enrichment observed in the heavy xenon isotopes
Performance and physiological responses of milk-fed calves to coated calcium butyrate supplementation

Field: Veterinary (Health Sciences)

The aim of this study was to determine the effects of coated calcium butyrate (CCB) on calf performance and some blood parameters. Sixteen female Holstein calves with a mean age of 3 ± 1 d were divided into two equal groups and fed a milk replacer supplemented with 3 g of coated calcium butyrate (CCB)/day or with no coated calcium butyrate (NCB). The calves had free access to solid feed and water. Body weight was measured at days 3, 12, 24, 36 and 48 (weaning day). Respiratory rate and rectal temperature (within first 4 weeks of life), feed intake and faecal score (during the whole experimental period) were recorded daily. Rumen fluid was taken for volatile fatty acid (VFA) determination on days 33 and 48, and structural growth (rump height, withers height and hip width) was recorded on days 3, 24 and 48. Blood samples were collected on days 1, 12, 24, 36 and 48. Feed intake, average daily gain, feed conversion ratio and structural growth of calves were improved by CCB supplementation. There were no significant differences on rectal temperature, respiratory rate and faecal score between the treatments. Rumen concentration of total VFAs increased and the VFA profile was affected on days 33 and 48 by CCB supplementation. The supplementation of milk replacer of calves with coated calcium butyrate significantly increased serum concentrations of glucose, insulin and β-hydroxybutyrate. Serum concentration of cortisol in the CCB calves was numerically lower than in NCB. In conclusion, supplementation of calves’ milk replacer with the coated calcium butyrate could improve calf performance.Keywords: Pre-ruminant, volatile fatty acids, blood parameters, structural growth, Holstein calves
Physiological, Perceptual, and Performance Responses to the 2-Week Block of High- versus Low-Intensity Endurance Training

Field: Medicine (Health Sciences)

ABSTRACT Purpose This study examined the physiological, perceptual, and performance responses to a 2-wk block of increased training load and compared whether responses differ between high-intensity interval (HIIT) and low-intensity training (LIT). Methods Thirty recreationally trained males and females performed a 2-wk block of 10 HIIT sessions (INT, n = 15) or 70% increased volume of LIT (VOL, n = 15). Running time in the 3000 m and basal serum and urine hormone concentrations were measured before (T 1 ) and after the block (T 2 ), and after a recovery week (T 3 ). In addition, weekly averages of nocturnal heart rate variability (HRV) and perceived recovery were compared with the baseline. Results Both groups improved their running time in the 3000 m from T 1 to T 2 (INT = −1.8% ± 1.6%, P = 0.003; VOL = −1.4% ± 1.7%, P = 0.017) and from T 1 to T 3 (INT = −2.5% ± 1.6%, P < 0.001; VOL = −2.2% ± 1.9%, P = 0.001). Resting norepinephrine concentration increased in INT from T 1 to T 2 ( P = 0.01) and remained elevated at T 3 ( P = 0.018). The change in HRV from the baseline was different between the groups during the first week (INT = −1.0% ± 2.0% vs VOL = 1.8% ± 3.2%, P = 0.008). Muscle soreness increased only in INT ( P < 0.001), and the change was different compared with VOL across the block and recovery weeks ( P < 0.05). Conclusions HIIT and LIT blocks increased endurance performance in a short period. Although both protocols seemed to be tolerable for recreational athletes, a HIIT block may induce some negative responses such as increased muscle soreness and decreased parasympathetic activity.
EXAFS: a new approach to the structure of micellar aggregates

Field: Chemistry (Physical Sciences)

A helical model was previously proposed for sodium (NaDC) and rubidium (RbDC) deoxycholate micellar aggregates in\naqueous solutions. SAXS, NMR, ESR, and CD meehurements verified the helical model. Here we report an EXAFS study\nby the spherical wave formalism on the coordination of the Rb' ions in the crystal, macromolecular fiber, and micellar aqueous\nsolution of RbDC together with measurements carried out on rubidium oxalate (crystal and aqueous solution). The results\nshow that the Rb" ions of the micellar aggregates have the same (or very similar) peculiar coordination as that inside the\nhelices of the crystal and macromolecular fiber. Moreover, their coordination remarkably differs from that observed in the\naqueous solutions of rubidium oxalate, where the situation would be similar to that of a classical micelle. Thus, the helical\nmodel is unquestionably confirmed.
