If you know of any more, post in the comments and let us know! Its contrail appears like a long tail of smoke in the sky. Their remains from the burning in atmosphere impact onto the ground. These contrail images were used along with observing data from eyewitnesses of fireball. From this information we can confirm the direction of fireball and burning tail of the meteorites.
From fireball which appeared in Thailand since September 7th , we can estimate the contact point by comparing photo of contrails to background star. The contact point could locate in Sai Yok national park, Kanchanaburi province, Thailand, which is the target of finding parts of meteorite. This research will report the proceeding of meteorite explore which might remain in that area. In this work, we study the Starobinsky's model of inflation in the context of gravity's rainbow theory.
We assume that the rainbow function can be written in the power-law form of the Hubble parameter. In addition, we clearly formulate the expressions of the spectral indices, the power spectra, and the tensor-to-scalar ratio associated with both scalar and tensor perturbations and we also compare the results of our model to Planck data.
Active Galactic Nuclei AGNs typically show variability on all time scales which can range from days to years. The purpose of this work is to study intra-year variability i. After standard image calibration, we use a custom-written pipeline based on publicly available software to produce light curves from our observation for future analysis.
We analyze the light curves to determine whether the target quasar shows intra-year variability and compare our photometry with the original HES data which was taken about 25 years ago to further study decade-scale variability.
Here, we present our current results of our light-curve analysis and show some particularly notable example, such as HE with significant variability over short timescales.
We present a multiwavelength investigation of the young stellar population and star formation activities in the HII region Sharpless The mass completeness of the identified YSO sample is estimated to be 1. The estimated dynamical age of the region, main-sequence lifetime of the ionizing source, the spatial distribution and ages of the YSOs indicate triggered star formation in the complex.
With and without physical context, we asked students to find out magnitude and graphical form of vector components. The problems were given to first year students of faculty of science during the third semester in academic year.
The students spent approximately 15 minutes of their General Physics I course to complete the open ended problems. Consequently, their responses were classified based on the similarity of errors performed in the responses. Others A majority of them produced errors and revealed alternative conceptions.
With physical context, only 6. Almost all of them drew other force vectors in any axis instead. It indicated that many students did not develop a strong foundation of understanding in vector components and could not apply those concepts to such problems with physical context.
Multiple representations are valuable tools used to help students learn how to think like physicists and understand physics concepts.
They can clearly represent the magnitude of the momentum before and after collision but they cannot be used to represent directions. This work shows a new but conventional and important representation—the momentum vector diagrams—teachers can use to help students apply conservation of momentum in two-dimensional collision. The momentum vector diagrams were used to teach grade students at a school in Bangkok in The other group of students at the same school was taught traditionally using conservation of momentum equations without drawing any momentum vectors.
The post-test results revealed that the former group performed better in solving two-dimensional collision problems. In addition, students who learned with momentum vector diagrams realized more that the situation in the problem was two dimension. In this study an alternative method based on interactive instructions was included in Introductory Physics lectures to facilitate student learning in the topic of circular motion. In a preliminary study, we found that the concept of circular motion was challenging for many students although they had already learnt this topic in high school.
They could not achieve the final step of problem-solving strategy which could possibly lead them to the correct answers. The specialized strategy was developed and provided in the lecture worksheet to guide students when they thought about solving circular motion problems.
The worksheet included not only the specialized strategy but also problems for students to practice in class. This helped engage students to work on problems with their peers which is the main aim of interactive instruction. The effectiveness of the specialized strategy was evaluated by comparing the results of an examination between two participant groups; one learning with non-specialized strategy and the other one with the specialized strategy. We found that number of students in the latter group who could solve the problem until achieving the correct answer is greater than the other one.
More interestingly, we also noted that the lower performance group was given the guided questions in the exam problem but the higher performance group was given the open-ended question. This asserts that the specialized strategy could help improve student abilities in solving circular motion problems. This paper presents a further development of a so-called Ticker, a device supporting "hear and see" activity in classroom or laboratory exercises.
While the original version of Ticker performs as a timing device, a new version of Ticker is improved in the sense of fast and wireless timing device. This wireless version provides the flexibility of measurements in various physics problems.
The wireless ticker composes of a photodiode, a simple circuit, a wireless transmitter and a buzzer. The photodiode is equipped to enable the fast rise time. The ticker is operated by the change of intensity of the detected light on its photodiode. The simple circuit sends the signal through the transmitter while the wireless receiver is connected to a personal computer.
Our developed software can be used to analyze the received signal. This new features of the ticker are meant to fulfill challenges in various teaching environments. The wireless ticker can also generate the ticking sound that aims to accommodate students with visual impairments.
The experiments on simple harmonics, simple pendulum and acceleration have been performed as examples to show the capability of the wireless ticker. The demonstration shows the promise of the wireless ticker as a new teaching tool. This economic device allows a huge room for creativity with simplicity of reliable measurements. This Study was to mainly explore how students' opinions toward Physics Recitation for Mechanics as undergraduate compulsory course by using Peer Instructiion. Aslo it was to study students' achievement on Mechanics Recitation test.
The qualitative and quantitative research approach were used to collect the data in the fall semester of at University of North Texas, USA. Both decriptive and inferential statistics were used to analyz the quantitative data. Meanwhile, qualitative data were collected by classroom observation and interview protocol. These data were analyzed by using content analysis. The result showed that their opinions were mostly positively, however, there were some concerns and suggestions to improve the course.
For students' Mechanics scores on recitation test were statistically significant different at 0. Rocket propulsion is a complex and hard to understand content of Mechanics subject.
We assigned for every class, 10 classes and students, in Grade 10 at Mahidol Witthayanusorn School for creating two home-made water rocket bottles for their class. The competition was held at the evening at February 18, The rule were the student have to launch rocket 2 time for aiming to target and got a score. After a competition, we assigned student for descripting their rocket by Physics perspective, the pros and cons of their rocket.
The result showed that the average of the perception is 4. The students had fun about this completion and they can better explain the rocket propulsion. This research use 3-axis accelerometer sensor with a signal wirelessly, to study of the motion of a pendulum clock and calculated gravitational field. The 3-axis accelerometer sensor and wireless transmitter will pack into pendulum clock. In experimental using to variance length of wire of pendulum clock at 20 cm, 40 cm, 60 cm, 80 cm and 93 cm.
The signal send from 3-axis accelerometer sensor pass wireless transmitter to computer by hypothermal program and analytic data by space sheet program. This experiment measure the time period from 3-axis accelerometer sensor are 0. The gravitational field of the earth calculate by the time period are 8.
From the result data, the short wire the error of gravitational field is higher than long length. Because time period is short so clock frequency time to send data of wireless transmitter do not enough. Glass-Ceramics is known to have very good mechanical properties while combining good properties from glass or ceramics which otherwise having them separately.
Such good mechanic properties allow machining to any desirable shape or form, which is important in ornamental or fashionable area. The thermal profile of glass transition and crystallization were studied by differential scanning calorimetry DSC. The crystal structure of the sintered glass-ceramics was carried out by X-ray diffraction XRD and the microstructure studies performed by scanning electron microscopy SEM.
The results show that devitrification of this glass system leads to glass-ceramics material. Its application in artificial opal gemstone work is foreseen. The composite was added chitosan with different concentration from 1 to 15 g and sintered at various temperature from to c with an increment c.
The results showed that the crystalline of composite was increased with increasing temperature. The porous of composite was appeared after sintered at c due to decomposed of chitosan.
The number and size of pore was depended on amount of chitosan. Hydroxyapatite is one of calcium phosphate phase and widely use in medical and dental application. Hydroxyapatite could be synthesized from natural calcium source. Cuttlefish bone waste are mainly composed of calcium carbonate.
This paper, hydroxyapatite was synthesized from cuttlefish bone by high energy ball milling technique. The heated cuttlefish bones at different temperature were mixed with di ammonium hydrogen orthophosphate ratio moles and added distil water 25 ml. The solution was milled at different time from 5 to min. The structure, morphology and function group of cuttlefish bone and hydroxyapatite samples were investigated with X-ray diffraction XRD , scanning electron microscopy SEM and Fourier transform infrared spectroscopy FTIR , respectively.
For hydroxyapatite synthesizing show that the samples were milled for 5 minutes not only hydroxyapatite phase appeared but also remained initial phase.
The pure hydroxyapatite phase appeared that the both aragonite and lime phase precursors were milled for 60 minutes. From experiment, the cuttlefish bone before and after heated can be use a source of calcium for hydroxyapatite synthesizing by high energy ball milling technique.
The morphology of hydroxyapatite were agglomerates and sphere particles. These experiments show that the hydroxyapatite could be synthesized from waste chicken eggshell and reduced time and cost for biomaterials application. However, some strong solar events can produce high energy ions with large intensity, which can penetrate to the lower atmosphere and produce significant ionization.
We have modeled this effect for the solar storm of 20 January , one of the strongest solar particle events ever recorded. This event produced energetic particles that can be detected by ground-based detectors, especially near the polar regions. We use the cosmic ray intensity vs. Then we performed Monte Carlo simulations of particle-air interactions using a realistic atmospheric model created from measured meteorological data to calculate atmospheric ionization at different altitudes and times for Inuvik and McMurdo.
For the case of galactic cosmic rays, our simulation results of atmospheric ionization are consistent with balloon measurements. We have also studied the equivalent dose rate at airplane altitude.
It is required equipment and technique for measuring of global solar radiation and its component in many regions. There are financial difficulties in limited solar radiation measurement especially in developing countries. In this study, Angstrom-Prescott model could be employ to estimate solar radiations for 11 stations in Thailand. The empirical coefficients have been determined by five empirical methods, i. The estimated solar radiation was determined with measured solar radiation by using statistical tests; mean percentage error, mean bias error, root mean square error and correlation.
The Princess Sirindhorn Neutron Monitor at Doi Inthanon, Thailand provides important information about high-energy cosmic rays from space. Both the neutron monitor NM and Bare lead-free neutron counters detect the variation of intensity in the interplanetary cosmic rays. Effects of recurrent geomagnetic storms RGSs induced by high-speed solar wind streams HSSs and corotating interaction regions CIRs on variations in daytime equatorial electric field EEF during have been investigated.
The EEF data as derived from magnetometer data together with the solar wind plasma data reveal many events of striking long duration of oscillating short-lived prompt penetration electric fields PPEFs about hours. The PPEFs exhibited different characteristics depending on the interplanetary origin. In some events, the northward turning of the IMF Bz is well consistent with quiet time value of the sym-H, which indicates the reduction in the rate of the reconnection.
Northern Thailand NT can be classified as the earthquake prone area, there are many active faults cutting through the area. The largest earthquake in Thailand modern history was also occurred on one of the active fault zones in the area on May 5th, In order to correctly estimate the epicenter and magnitude of the local earthquake, seismic velocity profile of the area is necessary which can be estimated from the receiver function RF studies.
In this study, during period of this study January — August , seismic data recorded by ten seismic stations in the northern Thailand were used to calculate receiver function time series.
Earthquake sources in this study incident crustal layers from different directions respect to source location e. Receiver function for each station then processed in two different schemes. First, for each station, all receiver functions were processed together to produce crustal thickness and velocity structure beneath the seismic stations.
Second, the tele-seismic waveforms were azimuthally classified according to its origin before processing to yield azimuthal RFs. Then Azimuthal RFs were used to estimate crustal thickness and velocity structures for each azimuth. The results reveal that both all RFs and azimuthal RFs yield similar result that crustal thickness increasing from 32 km in western part to about 40 km to the eastern part of NT.
Low velocity layer LVL can be observed with the waveform analysis. The nitrogen N -rich carbonaceous material has gained remarkable interest fueled by their potential use as high energy density materials for electrical storage.
Using this materials as primary components in supercapacitor electrode gives a superior ability to form double-layer charge coupling, therefore capacitance increase significantly. In this work, we introduce a novel method to convert biowaste into carbonaceous materials, in this case, spent coffee ground. The raw material is selected due to their naturally containing of high amount of nitrogen. The synthesizing process is composed of two major steps, hydrothermal and chemical activation using KOH.
The effect of chemical ratio between N-rich biochar and KOH on surface area and specific capacitance significant was investigated from — The resulted carbon structure obtained the nitrogen content as high as 1. Active galactic nuclei AGNs are signposts of accreting supermassive black holes at the center of active galaxies. They often have large and rapid variation in brightness, whose investigation can provide us with insights on the innermost environment of the accretion disk.
At X-ray wavelength, we obtain archival data in 2. Using these data, we then construct light curves of each AGN at both wavelength. Here, we present early result from the study that indicates marginal variabilities in X-ray and optical.
We will discuss the implications of variability limits on the fluctuation of power output of these AGNs in optical and X-ray. Weak gravitational lensing of galaxy cluster provides a direct method to probe their mass distribution. For each galaxy cluster, we determined the mass distribution from the radial shear profile, the mass-to-light ratio and the optical richness,in order to study how the galaxy population in clusters trace mass as a function of scale.
We have studied the scaling relation of mass with optical luminosity and richness for massive clusters. Moreover, by assuming that the average mass-to-light of galaxy clusters is very close to the cosmological values, we can determined the mass density of the universe.
RX Hydrae is a short-period 2d. This system was discovered by H. Short-periodic pulsations in a light curve of a primary component were detected by Kim et. We carried out the spectroscopic observations of this binary system in order to improve the binary system parameters and for spectroscopic study of pulsations in the primary component. Spectroscopic observations were acquired during 13 nights between with the 2.
We obtained new accurate orbital radial velocities of two components of the binary system and search for pulsational variability of the primary component. Results of these investigations and new orbital parameters are presented. The traditional method, spectroscopic reverberation mapping SRM , would fail for most high-z quasars and is inefficient for a large quasar sample. Photometric reverberation mapping PRM has been recently proposed in order to utilise the up-coming high cadence, large sky coverage and deep photometric survey of the next generation large telescopes such as LSST.
Such method is akin to the well established photometric redshift technique employed by cosmological community. In this talk, I will give a brief review of the PRM and highlight our on-going work of observational campaign at the 2.
The SDSS spectra were used to select spectroscopically confirmed quasars with redshift 0. We are completing the second observing season this April. The data are now being analysed and we will report the results of our study in the talk. Fast radio bursts FRBs are intense transient millisecond radio signal with large dispersion measures DM.
Radio signal, which propagates through cold plasma, is dispersed as frequency square. This can be interpreted as FRBs have an extragalatic origin. As DM is related to the free electron content along the line of sight, FRBs are expected to be use as a universe probe.
Until now, only 17 FRB have been detected. FRB has been found to be repeating 10 times since This research describes the results from the conceptual survey of 37 first-year undergraduate physics students 12 student of B. The results from all groups reveal that although most of them can give a meaning of twinkle light in general, but they cannot explain how light propagating from stars is twinkling. Some misconceptions such as the variation of stellar light intensity, some intensive or extensive properties of the light source etc.
The results from this research will be used to design the instruction which engages students to have a better understanding in twinkle light from celestial objects. The sets of learning activities on moment of inertia and applications for grade 11 students were designed and created and then used for active learning activities. The activities include the experiment of the relations between linear and angular velocities, moment inertia and related quantities, inquiry activity on rolling of objects with different shapes and radii, and law of angular momentum conservation.
The objectives of this research were 1 to study the efficiency of innovative learning. The respondents are63 second year students of the Faculty of Education of Bansomdejchaopraya Rajabhat University. The posttest is significantly higher than the pretest scores at.
The level of satisfaction in terms of students interest in innovation and knowledge understanding is 4. Students remarked that the innovation feature is interesting, novelty, easy to use, comprehensible, inexpensive and conveniently available.
The aim of this research is to design and create a test to measure the misconception about conservation of energy of the Thai high school students.
The design of the test was based on the learning theory in Cognitive Domain from Bloom's Taxonomy and each question is divided into three levels — three-tier question. On first tier it is a question about incident. Second tier question about why the first answer and the third tier is in response to a question about the confidence at first-second tier.
The test was submitted to two physics experts to check for correctness in physics details. Furthermore, the test was checked for content validity and item objective congruence by one education expert. Then this test will be used to measure the misconception of students participated in STEM-based activity. The objective of this research was to developing of scientific advances of liquid lens use the concept STEM education.
The samples of this research were 40 grade 11 students at Ratanaratbumrung School. In this research, students can learn about the liquid lens by demonstrations and design the experimental apparatus for study a contact angle, a focal length and a magnification of the lens witch STEM education is a curriculum based on the idea of educating students in four specific disciplines science, technology, engineering and mathematics. The measurement and evaluation is the test by scanning QR-code from Google Form program.
This research found that the class average normalized gain was high gain and the learner can design base for placing this glass slide on the camera of a mobile phone, this will enhance the imaging ability of the camera to similar to an optical microscope.
Furthermore, this research can integrated scientific knowledge of lens to solving problem in daily life. We reported the effect of boron addition on magnetic properties and structure of CoPt nanoparticles.
The CoPt-B nanoparticles were synthesized by means of the polyol process. The magnetic property measurement showed that the CoPt-B sample exhibited a much larger coercivity compared to the sample without B additive at the same annealing temperature. Transmission electron microscopy and energy dispersive X-ray spectroscopy revealed that the average particle size was about 2 nm for the as-synthesized sample with the ratio of Co and Pt was close to After annealing, the particle sizes increased but the composition was maintained.
The phase transformation of the nanoparticles versus temperature was investigated using a combination of X-ray diffraction and in-situ X-ray absorption analysis.
The evidence of B addition on the structure of CoPt nanoparticles was further supported by the magnetic measurements. Abstract Co0. The crystal structural, morphological and magnetic properties of ferrite were determined by X-ray diffractometry XRD , scanning electron microscopy SEM , and vibrating sample magnetometer VSM respectively. The result of samples show that cubic spinel ferrite and the crystallite size increases from 6.
The single crystal Co0. It was found that single crystal plane. We have synthesyzed Cu and Fe- doped TiO2 nanotubes by an anodization method. The electrolyte was composed of ethylene glycol EG , ammonium fluoride 0.
A constant DC power supply of 50 V was used during anodization with anodizing times of 2 hours. X-ray diffraction XRD was used to examined the microstucture and scanning electron microscopy SEM was used to viewed the surface morphology of the samples. The results show that TiO2 nanotubes are are anatase phases and the nanotubes are arraged in highly ordered arrays.
The transition metal ion dopants may be incorporated into the TiO2 structure. Dielectric properties were investigated over frequency range from 40Hz to 10MHz and temperature range from C to C. The behaviors of colossal permittivity can be explained by electron-pinned defect-dipoles, interfacial polarization and polaron hopping polarization. Method for fabricating a free standing film of colloidal photonic crystal CPC has been studied.
The CPC films were previously fabricated by drop-coating monodisperse polystyrene nanoparticles on agarose hydrogel. The water-based medium in these CPC films was not long-term stable and the changing of air-humidity resulted in the variation of their optical properties. To sustain the optical properties of CPC film, the gel medium in the film can be replaced by more stable materials with slightly changing the periodic ordered structure of crystalline colloidal array CCA.
A solid film was formed by shining UV light on the suspension to initiate the polymerization process. From this process, the CCA was fixed into the free standing film. The diffraction spectra from these free standing films were measured by optical diffractrometer. The shifting of diffraction peak of free standing photonic crystal film can be described by the decrement of the nanoparticle distance. Finally, its detection limit is reported as.
This hybrid organic-inorganic perovskite has recently gained intensive research interests due to their high efficiency as photovoltaic materials.
