A Study on Educational Technology Acceptance of Special Education Teachers in Language Teaching Based on TAM Model

The application of educational technology in special education is mainly to provide more convenient learning conditions for special students, so that special students can receive more learning opportunities and convenience. At this point, special education teachers’ acceptance of technology has become a crucial factor in improving the learning efficiency and effect of special students. Based on the Technology Acceptance Model (TAM), this study conducted a questionnaire survey of 112 special education teachers at different stages to investigate the level of special education educators’ acceptance and continuous use trend of educational information technology by descriptive statistics. Besides, t-test and ANOVA will be adapted to discuss the impact of various factors on the technology acceptance model. The results manifest that special education teachers’ educational technology acceptance was above average, but perception of the using easiness needs improvement. In addition, the educational technology acceptance levels of special education teachers are different in gender and teaching stages. Based on this, the article puts forward suggestions on the future of application of technology in special education from the three stages (identification & evaluation, training support and technical assistance) and two elements (family engagement and differentiated instruction).
Major and EDXRF Trace Element Chemical Analyses of Volcanic Rocks from Lassen Volcanic National Park and Vicinity, California

This open-file report presents WDXRF major-element chemical data for late Pliocene to Holocene volcanic rocks collected from Lassen Volcanic National Park and vicinity, California. Data for Rb, Sr, Ba, Y, Zr, Nb, Ni, Cr, Zn and Cu obtained by EDXRF are included for many samples. Data are presented in an EXCEL spreadsheet and are keyed to rock units as displayed on the Geologic Map of Lassen Volcanic National Park and vicinity (Clynne and Muffler, in press). Location of the samples is given in latitude and longitude in degrees and decimal minutes and in decimal degrees. INTRODUCTION This open-file report presents major element chemical data for late Pliocene to Holocene volcanic rocks collected during geologic mapping of Lassen Volcanic National Park and vicinity, California (figure 1). Most samples were colleceted in the area bounded by 40o 20', 40o 40' and 121o 7.5', 121o 45'). A few of the samples were collected from slightly beyond the area of the geologic map and are included here when required to characterize a map unit. An exception to this generality is that a number of samples of Maidu Volcanic Center rocks from south of the map area are included in order to augment the Maidu Volcanic Center data set. Samples collected in conjunction with thesis projects (Borg, 1989; Lerch, 1987) and geochemical studies (Feeley and others, in press) that were analyzed by the USGS are included. Some of the data presented herein were previously published (Borg, 1989; Clynne, 1984; Bullen and Clynne, 1990; Clynne, 1993; Clynne, 1999; Lerch, 1987; Muffler and others, 1994). Additional compositional and isotopic data for some samples can be found in Bacon and others, (1997); Borg (1989); Borg (1995); Borg and Clynne (1998); Borg and others (1997); Borg and others (2000); Borg and others (2002); Clynne (1990); Feeley and others (in press); Rose and others (1994); and Trimble and others, (1984). METHODS Samples were ground in an aluminum oxide shatter box. Bulk-rock major-element compositions were determined at the USGS Analytical Laboratory in Lakewood, Colorado by wavelength-dispersive X-ray fluorescence analysis of pressed powder pellets (Taggart and others, 1987). Trace elements were determined by Peggy Bruggman at Menlo Park by energy
Detection of pathotype of Marek's Disease in layer chicken in Iraq

Marek's Disease is a viral disease that affects poultry, particularly chickens. It is caused by the Marek's Disease Virus (MDV), which belongs to the herpesvirus family. The disease is characterized by the formation of tumors in various organs, including the nerves, skin, and internal organs such as the liver, spleen, and kidneys. A layer poultry farm of one day old, vaccinated with Marek's disease virus vaccine. The flock was infected with a virulent Marek's disease virus with a mortality rate of up to 60%. Histopathological examination of affected tissues is an important tool for the diagnosis of the disease. The histopathological finding of tissue sections from chickens with MDV shows extensive proliferation of lymphocytes of various sizes. The confirmation was done by PCR and standardized targeting a 132 bp tandem repeat region specific for serotype-1 MD viruses Meq gene was carried out by PCR and nucleotide sequencing, The sequence analysis of Meq gene of different clinical cases from Iraq homology with very virulent strain and Phylogenetic analysis of oncogenes was carried out with other available sequences in the GenBank we conclude that MDV strains obtained in the present outbreaks in Iraq could be designated as very virulent pathotypes based on nucleotide and phylogenetic analysis of the viruses.
Synthesis of highly-porous nitrogen-doped carbon materials by pyrolysis of melamine-formaldehyde resin using a hard template

The use of nitrogen-doped carbon materials as electrodes in supercapacitors is a promising area of research. In this study highly-porous nitrogen-containing carbon materials were obtained by pyrolysis of melamine formaldehyde resin in the presence of nanocrystalline MgO as a hard template that was washed off after the pyrolysis. Magnesium citrate was used as a precursor for the synthesis of the template agent in situ during the pyrolysis of the resin. The obtained materials were characterized by X-ray diffraction, BET nitrogen adsorption method and Raman spectroscopy. The presence of nitrogen in the amount of 4 atomic percent was proved by XPS spectroscopy. The specific surface area was found to increase monotonically from 10 to 1300 m2/g with an increase in the content of magnesium citrate in the initial mixture. The samples showed high capacitance of 120 F/g in 1 M H2SO4 electrolyte and can be used in supercapacitors.
Manufacturing Scalable Carbon Nanotube–Silicone/Kevlar Fabrics

Carbon nanotube (CNT) hybrid composites were formed by combining a CNT and silicone elastomer solution with Kevlar yarn, Kevlar fabric, and Kevlar veil materials. The integration of a CNT-silicone matrix with Kevlar yarn and fabric materials produced a composite with moderate electrical and thermal conductivity due to CNT fabric combined with the strength of Kevlar fabric or yarn. In the material synthesis, a notable difficulty was that the CNT-silicone did not bond strongly to the Kevlar. The composites passed the Vertical Flame Test ASTM D6413 and the Forced Air Oven Test NFPA 1971. These hybrid composites can have multiple applications in areas requiring favorable conductivity, strength, and flame and heat resistance. The application areas include firefighter apparel, military equipment, conductive/smart structures, and flexible electronics. The synthesis process used to manufacture CNT-silicone/Kevlar composites yielded composite sheets with an area of 2250 cm2. The process is scalable and customizable for the synthesis of CNT composites with tailored properties. Improvements in the bonding of CNT-silicone to Kevlar are being investigated.
Estimating UK methane and nitrous oxide emissions from 1990 to 2007 using an inversion modeling approach

[1] Methane (CH4) and nitrous oxide (N2O) have strong radiative properties in the Earth's atmosphere and both are regulated through the United Nations Framework Convention on Climate Change. Through this convention the United Kingdom is obliged to report an inventory of annual emission estimates from 1990. This paper describes a methodology that estimates emissions of CH4 and N2O completely independent of the inventory values. Emissions have been estimated for each year 1990–2007 for the United Kingdom and for NW Europe. The methodology combines high-frequency observations from Mace Head, a monitoring site on the west coast of Ireland, with an atmospheric dispersion model and an inversion system. The sensitivities of the inversion method to the modeling assumptions are reported. The 20 year Northern Hemisphere midlatitude baseline mixing ratios, growth rates, and seasonal cycles of both gases are also presented. The results indicate reasonable agreement between the inventory and inversion results for the United Kingdom for N2O over the entire period. For CH4 the agreement is poor in the 1990s but good in the 2000s. The UK CH4 inventory reported reduction from 1990–1992 to 2005–2007 (over 50%) is dominated by changes to landfill and coal mine emissions and is more than double the corresponding drop in the inversion estimated emissions (24%). The inversion results suggest that the United Kingdom has met its Kyoto commitment (−12.5%) but by a smaller margin (−14.3%) than reported (−17.3%). The results for NW Europe with the United Kingdom removed show reasonable agreement in trend, on average the inversion results for N2O are 25% lower and for CH4 21% higher.
Diurnal predators of restocked lab-reared and wild Diadema antillarum near artificial reefs in Saba

The long-spined sea urchin Diadema antillarum controls reef dynamics by grazing on algae and increasing coral recruitment. Populations of Diadema never recovered after a mass-die off in 1983 and 1984, and numbers were further reduced by a more recent die-off in 2022. To restore grazing pressure and thereby the resilience of Caribbean coral reefs, multiple Diadema restocking efforts have been performed. Although results vary, relatively low retention is one of the reasons restocking is not considered more often. If causes for the low retention can be identified, suitable measures may be able to increase restocking success. In this study, we monitored restocked lab-reared and wild juvenile Diadema on artificial reefs around Saba, Caribbean Netherlands. To assess the retention of Diadema over time, we conducted diver surveys and used underwater photo time lapse during daylight. Retention of uncaged lab-reared and wild Diadema decreased steadily with less than 30% surviving after 10 days. In total, 138 predator-prey interactions were recorded, of which 99% involved the queen triggerfish Balistes vetula, although other potential predators were present in the area. None of the recorded predator-prey interactions was successful, which suggests that artificial reefs with incorporated shelters may be suitable for juveniles as daytime refuge. However, Diadema that were more often attacked during the day were more likely to be absent the next morning. Because queen triggerfish often visited the experimental site in the first or last hour of daylight, it could be that they were more successful in their attacks when it was too dark to see anything on the photos and when Diadema came out to feed or to look for better shelter opportunities. If Diadema migrated off the artificial reef, they were probably predated during the process, because no Diadema were found on surrounding reefs. Wild Diadema were attacked significantly more often than lab-reared Diadema, possibly because the wild urchins were larger, but this did not significantly affect retention. Future restocking should be performed on natural or artificial reefs with deeper shelters, so Diadema can retract farther into their crevice, and should include night-time monitoring to identify the remaining unknown factors that cause low retention, including migration and nocturnal predation. This knowledge is urgently needed to coral reef managers so they can increase Diadema restocking success by selecting reefs with a lower predator density, protect urchins during an acclimatization period and/or conduct temporary predator control measures.
Nonparametric estimation of exact consumers surplus and deadweight loss

The authors apply nonparametric regression models to estimation of demand curves of the type most often used in applied research. From the demand curve estimators they derive estimates of exact consumers surplus and deadweight loss. The authors also develop tests of the symmetry and downward sloping properties of compensated demand. They work out asymptotic normal sampling theory for kernel and series nonparametric estimators as well as for the parametric case. The paper includes an application to gasoline demand that estimates the shape of the demand curve and the average magnitude of welfare loss from a tax on gasoline.

Fast Single-Mode Fiber Nonlinearity Monitoring: An Experimental Comparison Between Split-Step and Nonlinear Fourier Transform-Based Methods

We experimentally investigate the problem of monitoring the Kerr-nonlinearity coefficient <inline-formula><tex-math notation="LaTeX">$\gamma$</tex-math></inline-formula> from transmitted and received data for a single-mode fiber link of 1600 km length. We compare the accuracy and speed of three different approaches. First, a standard split-step Fourier method is used to predict the output at various <inline-formula><tex-math notation="LaTeX">$\gamma$</tex-math></inline-formula> values, which are then compared to the measured output. Second, a recently proposed nonlinear Fourier transform (NFT)-based method, which matches solitonic eigenvalues in the transmitted and received signals for various <inline-formula><tex-math notation="LaTeX">$\gamma$</tex-math></inline-formula> values. Third, a novel fast version of the NFT-based method, which only matches the highest few eigenvalues. Although the NFT-based methods do not scale with link length, we demonstrate that the SSFM-based method is significantly faster than the basic NFT-based method for the considered link of 1600 km, and outperforms even the faster version. However, for a simulated link of 8000 km, the fast NFT-based method is shown to be faster than the SSMF-based method, although at the cost of a small loss in accuracy.
Physical activity, problematic smartphone use, and burnout among Chinese college students

The aim of this study was to investigate the association between physical activity (PA), problematic smartphone use (PSU), and burnout, as well as to identify whether there is a mediating role for PSU. We recruited 823 college students (Mage = 18.55, SD = 0.83) from Wuhan, China, in December 2022, including 499 males and 324 females. Demographic information, the International Physical Activity Questionnaire-Short Form (IPAQ-SF), the Smartphone Addiction Scale-Short Version (SAS-SV), and the Maslach Burnout Inventory-Student Survey (MBI-SS) were used for assessments. Pearson correlation analysis showed that PA was significantly associated with PSU (r = −0.151, p < 0.001), PSU was significantly associated with burnout (r = 0.421, p < 0.001), and the association between PA and burnout was not statistically significant (r = −0.046, p > 0.05). The results of the mediation model test showed that PA could not predict burnout directly; it instead predicted burnout entirely indirectly through PSU. Furthermore, PSU mediated the predictive effect of PA on exhaustion and cynicism. In conclusion, there is no direct connection between PA levels and burnout. PA indirectly affects burnout through PSU, but does not fully apply to the three different dimensions of exhaustion, cynicism, and professional efficacy.
A modified Phong-Blinn light model for shadowed areas

The human visual system makes use of the information that shadows provide in order to determine the location of objects. In computer graphics rendered scenes, it can sometimes be difficult to determine whether an object is floating in the air or is placed on the ground. There are two types of shadows. One occurs when an object occludes another object so that light cannot reach it. Instead of using ambient light, as the PhongBlinn model suggests, for these shadows, the light intensity is decreased making an impression of a shadow. This will prevent the shadow from appearing flat, as it would if only ambient light where used. The other type of shadow, is visible on all polygons facing away from the light source and are therefore not lit. Usually, ambient light only is used for these shadows. We propose an improvement to the Phong-Blinn model, which will make these shadowed polygons more realistic and not appear so flat. This will especially improve the visual appearance of bump mapped objects where the bumps will be visible also on the back-faces.
PARKING SURVEY - METHODOLOGY AND CASE STUDY

For first time in Sofia, capital of Bulgaria was carried out survey on parking capacity, duration and behavior and in large administrative and residential center. For the purpose of the survey methodology was developed, which in short terms, is as follows: for each parking place by pre-defined parking area can be determined the nature, frequency and duration of use. During the survey, one or more counters for several times, consistent and walk a predetermined route on foot. The counter recognize site of parking place on a map and record the registration number of all vehicles parked. If necessary, you can distinguish the category of car parking (free, paid per hour, service subscription). Also, erroneous and/or illegally parked vehicles may be registered separately. Methodology was created and then applied in GIS and database for automated mapping of results and generate a series of reports from analysis. The methodology is appropriate to collect the following information:  category of use of the parking place;  use of parking spaces on the street;  residence time;  period of cycle parking;  total number of vehicles in one area during the measurement;  change and localization of parking capacity  relevance of the parking category. Through the methodology can be made for further analysis: the actual use of parking places and parking it in a category; how the trend is moving on parking during the day; Mapping of the parking lot; The use of additional parking facilities serving; nature, duration and extent of illegal parking determining or changing categories in parking area; Preparation and design of new parking or review existing parking
Unveiling the behavioral nexus of innovative organizational culture: Identification and affective commitment of teachers in primary schools

ABSTRACT A rigorous revision of the current body of literature is required to obtain an accurate assessment of the impact of innovative organizational culture on teachers’ identification and affective commitment in primary school environments. The current literature requires more investigation into the mediating function of teachers’ identification in the relationship between innovative culture and teachers’ affective commitment. This underscores the necessity for a more comprehensive comprehension of this mediating mechanism. Therefore, through combining two theoretical frameworks, Behavioral Commitment Theory (BCT) and Social Identity Theory (SIT), this study delves into the intricate psychological interplay between innovative organizational culture and its influence on teachers’ sense of identification and affective commitment in primary schools, which could provide insight into more understanding of this phenomenon. By surveying 432 teachers, this study sought to discern the direct impacts of an innovation-driven culture on teachers’ organizational identification and affective commitment and the potential mediating role of this identification. The findings of this study, which were inferred from the Structural Equation Modeling (SEM), illuminate that an innovative atmosphere significantly resonates with teachers’ identification and affective commitment. Additionally, this identification emerges as a bridge that further intensifies teachers’ emotional bond (affective commitment) with their institution in the context of innovation culture. This research contributes valuable insights for educational institutions and provides practical implications for students, teachers, and schools, while highlighting certain constraints and avenues for future exploration.
Magmatic Ni-Cu versus PGE deposits: Contrasting genetic controls and exploration implications

Both Ni-Cu and PGE deposits are associated with mafic and ultramafic rocks, but the former often occur in dynamic magmatic systems such as lava channels and magma conduits whereas the later occur in larger layered intrusions. The contrasting modes of occurrence appear to be related to different degrees of preferential partitioning of the metals (PGE versus Cu and Ni) into segregating sulfide liquid and different concentration processes of the sulfide liquid during the formation of the ores. Primary magmas derived from partial melting of the upper mantle are fertile in PGE, Ni and Cu only when the molten sulfides are completely dissolved in the magmas. This requires a high degree of partial melting of the mantle, perhaps higher than 30 percent. The partial melts usually have basaltic to komatiitic compositions, and are unlikely to achieve sulfide saturation during ascent to the crust. Fractional crystallization and crustal contamination are the most important processes known to have induced sulfide saturation in magma upon intrusion. Sulfide liquid segregated in a large chamber may achieve high R-factors required for the formation of reef-type PGE deposits. Crustal assimilation appears to be most effective in dynamic lava channels and magma conduits. A large volume of sulfide liquid segregated from magma in such dynamic environments often has a lower R-factor, and relatively lower metal concentrations. Such metal-poor sulfide liquid needs to be deposited in restricted localities, and/or to be upgraded in metals by reacting with new surges of magma, to become a Ni-Cu sulfide deposit. Because of their extremely high partition coefficient between sulfide liquid and magma, PGE will become significantly depleted in magma even at small amounts of sulfide segregation. Copper, on the other hand, will be much less depleted because of its relatively low partition coefficient. Thus, Pd/Cu ratios in whole rocks can be used to detect PGE mineralization associated with small sulfide segregation in large layered intrusion. The whole rock Cu/Zr ratio is sensitive to large amounts of sulfide liquid segregation from magma and thus is a useful tool for Ni-Cu exploration. Nickel contents of olivine can also be used to identify Ni depletion in magma associated with large amounts of sulfide segregation.
Is muscle stiffness a determinant for range of motion in the leg muscles?

Previous training studies with comprehensive stretching durations have reported that an increase in range of motion (ROM) can be related to decreases in muscle stiffness. Therefore, the purpose of this study was to analyze the association between the passive muscle stiffness of three muscle groups (triceps surae, quadriceps, hamstrings) to the respective joint ROM. Thirty-six healthy male soccer players volunteered in this study. After a standardized warm-up, the muscle stiffness was tested via shear wave elastography in six muscles (gastrocnemius medialis and lateralis, rectus femoris, semitendinosus, semimembranosus, and biceps femoris long head). The hip extension, hip flexion, and ankle dorsiflexion ROM were also assessed with a modified Thomas test, a sit and reach test, and a standing wall push test, respectively. We found significant moderate to large correlations between hip flexion ROM and muscle stiffness for the semimembranosus (rP = –0.43; P = 0.01), biceps femoris long head (rP = –0.45; P = 0.01), and overall hamstring stiffness (rP = –0.50; P < 0.01). No significant correlations were found for triceps surae (rP = –0.12; P = 0.51 to 0.67) and rectus femoris muscle stiffness (rP = 0.25; P = 0.14) with ankle dorsiflexion and hip extension ROM, respectively. We conclude that muscle stiffness is an important contributor to hip flexion ROM, but less important for hip extension or ankle joint ROM. Additional contributors to ROM might be tendon stiffness or stretch/pain tolerance.
