title: Energy of unitary cayley graphs and GCD-Graphs

description: This work is based on ideas of Ilic on the energy of unitary Cayley graph. We study the eigenvalues of the unitary Cayley graph of a finite commutative ring and some gcd-graphs and compute their energy. Moreover, we apply these results to obtain the energy of the complement of unitary Cayley graphs and of the restricted unitary Cayley graphs on quadratic residues.

title: Theoretical investigation of gas–sensing properties of ZnO nanosheets

description: The structure optimizations of all configurations of gaseous O₂, CO, NO, NO₂, N₂O, NH₃, H₂ and H₂O molecules adsorbed on ZnO nanoclusters (ZnONCs), aromatic–like (AL–ZnONC), naphthalene–like (NLL–ZnONC), pyrene–like (PRL–ZnONC) and ZnO graphene–like nanosheets (ZnOGLNSs), coronene–like (CNL–ZnONS) and circumcoronene–like (CCL–ZnONS) were carried out using the B3LYP/LanL2DZ calculations. Adsorption energies of these gases on AL–ZnONC, NLL–ZnONC, PRL–ZnONC, CNL–ZnOGLNS and CCL–ZnOGLNS were reported. It was found that only O2 was chemically adsorbed via the hydride atoms of zinc–hydride in the ZnONCs and ZnOGLNSs whereas the other gases are not. In terms of physisorptions, only O₂ molecule was adsorbed over the plane of ZnOGLNSs. As the energy gaps of ZnOGLNSs were largely reduced after adsorption of O₂, NO or NO₂, these ZnOGLNSs were therefore be the sensing materials for there gases. It was found that adsorption of CO, H₂, H₂O, NH₃ and N₂O on ZnOGLNSs were somewhat weak, and thus these ZnOGLNSs were hardly sensing to these gases.

title: Effects of Lorentz symmetry violation in cosmological models

description: Lorentz symmetry is a fundamental symmetry in nature. It plays an important role in both particle physics in microscopic quantum scale and gravitation theories in macroscopic scale. However, this symmetry is expected to be broken at the Planck scale as the effect suggested from quantum gravity. It is possible that some consequent effects of Lorentz violation can be found in the low-energy effective field theories. Investigations on the Lorentz violation effects gain a lot of attention over the past ten years and many approaches to study these effects have been developed. The Lorentz violation effects in cosmological models are provided by the existence of the æther field. In this thesis, an investigation of the æther field effects is divided into two parts, time-like and space-like æther field. For the time-like æther field, the constraints for the æther parameters are imposed by several experiments. The æther parameters are also constrained by the stability of the models. The effects of the viable time-like æther field in inflationary models are reviewed. The dynamics of inflation is slightly modified and the primordial perturbations are significantly changed. For the effects of space-like æther field on the cosmological models, we consider the Maxwell-like æther field in the Casimir dark energy models in 5-dimensional spacetime. In the Casimir dark energy models, the mechanism for stabilizing the extra dimension are destroyed when non-relativistic matter is taken into account. It is found that the æther field can reduce the effective force acting on the radion field. The radion field will be slowed down before it passes the minimum of the potential. Therefore, the radion field can settle down at the minimum of the potential and the stability is restored.

title: Effects of short break neck stretching on neck pain and surface EMG median frequency changes in office workers

description: Objectives: To study the effects of 4 weeks between stretching and breathing exercise on pain level via the Visual Analog Scale (VAS), surface EMG median frequency(MF), and the neck disability index (NDI) in chronic neck pain female office workers who are prolonged computer users.Materials and methods: 60 Thai female office workers with chronic neck pain aged between 25 – 35 years old. 30 of stretching group (ST) stretched both upper trapezius (UT) and cervical erector spinea (CES). 30 of breathing exercise group (BE) did diaphragmatic deep breathing for relaxation. Both groups did exercise twice a day during working day. VAS, MF, and NDI were used before and after 4 weeks.Result: VAS showed decreasing the intensity both group (p&lt;0.001). ST provided no significant decreased MF on Lt. CES and Lt. UT (p&lt;0.05) but Rt. CES and Rt. UT was significant deceased MF (p&lt;0.05). BE demonstrated fatigability by significant decreased MF (p&lt;0.05). NDI score was lower than before program significantly in both groups (p&lt;0.001).Conclusion: ST with this protocol provided improved pain level, quality of life, and muscle fatigability on the left side. BE contributed did not improve only muscle fatigability. Thus, ST was potential reduce chronic neck muscle pain. Thus, both of these protocols could be improved pain intensity and quality of life in chronic neck pain from prolonged computer task.

title: Parkes observations for project P456 semester 2019APRS_50

description: The Parkes Pulsar Timing Array (PPTA) project has three primary goals: (a) detection of gravitational waves from astronomical sources, (b) establishment of a pulsar timescale, and (c) improvement of our understanding of Solar-system dynamics. The PPTA is the oldest of three international pulsar timing groups. We have the smallest telescope and the smallest group, but the best measurements and the best results. Our bound on the strength of the incoherent gravitational wave background is the only bound which significantly constrains theoretical models. We have maintained our leading position because: we have the southern sky; we have a small but well-focussed group; we have the best-calibrated receivers; and we have been able to observe with an almost regular cadence of 15 to 20 days over a wide bandwidth. With this proposal we aim to maintain our pre-eminent position in the field. Unlike most observing proposals, this is a continuing proposal for which the observations will continue to improve bounds on ultra-low-frequency gravitational waves until they are finally detected. Continued Parkes observations will remain valuable at least until the first stage of the SKA is able to improve on our sensitivity and observing cadence. Even after the gravitational wave background is detected we will want to continue observations in support of the nascent field of gravitational wave astronomy!

title: The Effect of dental diseases on mucosal thickening and mucosal cysts of the maxillary sinus

description: Background: Mucosal thickening and mucosal cysts of the maxillary sinus are commonly observed among asymptomatic subjects. The role of dental diseases on these abnormalities was unclear. The aim of this study is to determine the relationship between dental diseases and mucosal thickening/ mucosal cysts of the maxillary sinus. Methods: The computed tomographic (CT) images of 250 consecutive subjects who underwent CT scans for dental treatment purposes were studied. Dental findings including periodontal bone loss, periapical lesions, and root canal fillings were assessed. The presence of mucosal thickening and mucosal cyst of the maxillary sinus was recorded. Logistic regression analysis was used to determine the influence of dental findings on these sinus mucosal abnormalities. Results: The prevalence of mucosal thickening was 42% and of mucosal cysts was16.4% of subjects, both being more frequent in males than in females. Periodontal bone loss was significantly associated with mucosal thickening whereas periapical lesions and root canal fillings were not. Presence of severe periodontal bone loss increased risk of mucosal thickening by 3 folds (OR=3.02, P

title: Contraception usage among married women of reproductive age in Mandalay, Myanmar

description: The objective of this study was to determine contraceptive usage and its association with socio-demographic factors, knowledge about contraception, attitudes towards contraception among 358 married women of reproductive age residing 2 townships in Mandalay, Myanmar. The data of this face to face interview study was analyzed by chi-square test to understand the association between independent factors and current contraception usage.The study revealed that 43% of the women in the two townships in Mandalay were 25 to 34 years of age. 44.7% reported being married for more than ten years; more than half had 1 to 2 children and were housewives. Nearly all were Buddhist. Nearly half of the women had an income 50,001-100,000 Kyat per month.The prevalence of contraceptive use among married women was 53.4%. The most commonly used methods were oral pill and injectables. The common reasons for not currently using contraceptives were being afraid of side effects, wanting to get pregnant, health reasons and husband objecting. Most of the women heard of contraceptive methods and half correctly answered 50-70% of the knowledge questions. Only 13 to 19% of women had a favorable attitudes towards contraception use.The relationship between independent variables and current usage of contraception was analyzed by chi-square test. The result showed that 21 to 30 years old, those with 1 to 2 children, women married for 6 to 10 years, women with more knowledge and women with a moderate level of attitude towards contraception are significantly more likely to be contraceptive users. This information is needed to help educate women about contraception.

title: The Cosmogrid Simulation: Statistical Properties of Small Dark Matter Halos (2048-759)

description: We present the results of the "Cosmogrid" cosmological N-body simulation suites based on the concordance LCDM model. The Cosmogrid simulation was performed in a 30 Mpc box with 2048³ particles. The mass of each particle is 1.28x10^5 Msun, which is sufficient to resolve ultra-faint dwarfs. We found that the halo mass function shows good agreement with the Sheth & Tormen fitting function down to ~10^7 Msun. We have analyzed the spherically averaged density profiles of the three most massive halos which are of galaxy group size and contain at least 170 million particles. The slopes of these density profiles become shallower than -1 at the inner most radius. We also find a clear correlation of halo concentration with mass. The mass dependence of the concentration parameter cannot be expressed by a single power law, however a simple model based on the Press-Schechter theory proposed by Navarro et al. gives reasonable agreement with this dependence. The spin parameter does not show a correlation with the halo mass. The probability distribution functions for both concentration and spin are well fitted by the log-normal distribution for halos with the masses larger than ~10^8 Msun. The subhalo abundance depends on the halo mass. Galaxy-sized halos have 50% more subhalos than ~10^11 Msun halos have. This is snapshot 759 of the 2048³ resolution collection.

title: Parkes observations for project PX501 semester 2019APRS_20

description: This proposal relates to time purchased by the Chinese Academy of Sciences for Parkes follow-up confirmation and timing of FAST discoveries. As the observing time has been purchased this proposal (and the related PX500) does not require TAC grading. The primary reason for submitting a proposal is to ensure an outreach statement and that the proposal is entered into OPAL for the data archive to access. The Chinese team have two time requests. The time scheduled for the first (PX500) will be allocated in blocks of 24 hours and the data will become available in the data archive with an 18 month embargo period. The second type of time (relating to this proposal) will be scheduled in shorter blocks and the data archived with a 10 year embargo.

title: Measurements of atmospheric radioactivity dose rates over the North Pacific after the Fukushima Daiichi nuclear power plant accident during the period March 2011 - March 2015

description: On 11 April 2011, a magnitude 9.0 earthquake occurred about 154 km northeast of the Fukushima Daiichi Nuclear Power Plant (FNPP1; $37.420^{\circ}N$ and $141.033^{\circ}E$). Here we present continuous measurements of the atmospheric dose rates after the Fukushima accident over the North Pacific atmosphere by a fleet of thirteen in-service global container cargo ships and another at a Tokyo port site from the Taiwanese PGGM (Pacific Greenhouse Gases Measurements) project. The continuous measurements of atmospheric dose rates were collected from a total of 294 cruises with 41,485 measurements during the period March 2011 to 2015. <br> In this work, we identify three key aspects of the impacts of the radioactive materials following the Fukushima accident: The altitude effect, the land surface effect, and the transported effect. We showed measurements of air dose rates over the land surface area and over the oceanic atmosphere. The striking differences in the air dose rates measured during the 2011-2015 period clearly identify the deposition effects and the effects associated with radioactive materials transported from the FNPP1. Air dose rates measured over the land surface areas resulted from a combination of the effects from the deposition of radioactive materials on the surface and the radioactive materials contained in the airborne particles. Air dose rates measured over the oceanic atmosphere contains radioactive effects from airborne particles. The data of air dose rates over the North Pacific atmosphere show the eastward transport of radioactivity. <br> Eastward transport of radioactive materials had been observed after 11 Mar 2011. Monitoring data show that the export of radioactive materials to the Pacific atmosphere occurred after March 2011, and in 2012, 2013, 2014, and 2015.

title: ASD01 Stream discharge for Kings Creek measured at USGS gaging station

description: The 1060 hectacre Kings Creek watershed (STATION NUMBER 06879650) is a U.S. Geological survey hydrologic benchmark. (cf. Cobb, e.D. and J.E. Beisecker. 1971. USGS circular 460-d) flow is measured continuously with a bubble gage. The period of record started in March, 1979. The hydrologic regime is driven by the mid-continent climate characterized by summer thunderstorms and drought. The stream, at the gaging station, is fourth order in gallery forest. The riparian vegetation in the headwaters (1st & 2nd order) is tallgrass, or true, prairie. Flow occurred in spring and early summer in all years. Late summer, fall and winter records also include periods of no flow, the longest of these was ca. nine months. The time from base flow to peak flow for typical storm flow hydrographs is an hour or so and amplitude of ca. three meters above base flow has been recorded (Data comes from USGS office in Lawrence, Kansas; Contact person:Butch Lawcock, (913) 842-9709).

title: A study of building response to ground vibration : ambient vibration approach

description: In urban area where space is limited, it is unavoidable for construction works to be carried out near to existing structures. In such situation, the increasing risk of vibration-induced damage on the buildings can be seen and has to be managed appropriately. To alleviate the problem, there are three areas that measures can be taken: vibration sources, propagation mediums, and buildings subjected to vibration. This study focused on the last factor and tried to evaluate how buildings respond to ground motions by determining their transfer functions. The transfer function (TF) is the ratios between the output and input in frequency domain of a linear system. For ground-borne vibrations, the system is the soil through which elastic wave propagates and the output is the motion at any location of interest, for instance, on the surface or within the ground or anywhere in building subjected to vibration. In this study, twopoint measurements of ambient vibration were used to derive a transfer function between ground and building motions. Then, the obtained function was used to predict the response of the same building against vibration due to the demolition of nearby structures. By verification with vibration generated by a demolition work, the measured Peak Particle Velocities seem to be slightly underestimated by the proposed method. Nonetheless, the study showed that ambient vibration can be used to predict the building response with a moderate degree of determination.

title: MassIVE MSV000084401 - GNPS_GC-MS preliminary data_Trachymyrmex septentrionalis fungus garden
title: Preliminary data of volatiles from T. septentrionalis fungus gardens. Samples were obtained directly from their chambers maintained under laboratory. The samples correspond to an entire and healthy fungus garden and subcolonies of fungus garden inoculated with Trichoderma sp. A polydimethylsiloxane (PDMS) piece of approximately 1x2 cm was placed inside a fungus garden. Exposure of the SE was allowed for 3 h. Each sample was individually transferred to a clean 2 mL borosilicate vial using clean tweezers and capped with a crimp camp with silicone septum. The GC-MS analysis was carried out using the Agilent 7200 GC/QTOF equipped with robotic sampler system. The PDMS within each vial was heated for 20 minutes at 200 oC to desorb volatiles from the PDMS and 0.5 mL of headspace injected (injector temperature set at 250 oC) into the instrument with a headspace syringe heated to 145 oC. The GC parameters were set as it follows: starting temperature 45 oC; 50 oC/min oven ramp to 100 oC (hold of 0.1 min), 15 oC/min oven ramp to 300 oC (hold of 0.1 min), and 50 oC/min oven ramp to 320 oC to purge the column. The separation was conducted on HP-5MS column (30 m x 0.25mm x 0.25 um). The helium carrier gas was set to constant 1.2 mL/min flow and a splitless injection mode was applied. The scanned m/z range was 35-400 Th with the acquisition rate of 10 spectra/s.

title: Effect of Sugar Substitution by Stevia Extract on Sensory Acceptance, Color, and Texture Profiles of Brownie

description: Currently, consumers pay more attention to health and consumption more healthy foods. Substitution of sugar with natural sweetening agents in sweet products is another interesting option. This research purposed to study the application of stevia extracts to replace sugar in brownies. Stevia leaves were extracted with water at 55?C for 6 h prior to drying using a spray dryer to obtain stevia extract powder. The sugar was replaced by the stevia extract powder with the degree of substitution of 0.125, 0.25, 0.375, and 0.50%. The sensory evaluation of brownies was evaluated by 50 panelists using 9 points hedonic scale. The results indicated that the brownies contained 23.07% of sugar and 0.125% stevia extract powder received the highest liking score which is comparable to those of control brownie sample. For the study on the effect of the addition of stevia extract powder on the color of brownie, it was observed that the brightness value of brownie was affected by the stevia extract added, the more level of the stevia extract powder added, the lower the brightness obtained. For the texture characteristics of the brownie, it was found that the addition of stevia powder significant effect all texture profiles of brownies. Therefore, the application of stevia extract powder to replace sugar is possible. However, further studies on the effect of replacing sugar by stevia extract powder on texture characteristics and nutritional value are needed.
