In the same way, we may add or remove credence from the multiverse theory even without newly collected measurements on directly testable predictions.Plenary Session APOGEE: The New View of the Milky Way (by Nathan Sanders)Jo Bovy (Toronto) spoke about a bevy of recent discoveries by the APOGEE team, which has collected half a million spectra of red giant stars throughout the Milky Way disk. Bovy emphasized APOGEEs unprecedented scope, covering close to half of the Milky Way disk and ranging ~10 kpc in radius, rather than the tiny neighborhood around the sun that most historical stellar surveys have probed. Overcoming the challenges of galactic extinction, the APOGEE team has made the most precise measurement of the circular rotation velocity of the MIlky Way disk, v_c = 218 +- 6 km/s, and produced remarkable results on the chemical evolution history of the Galaxy. In particular, they have shown that the star formation and chemical evolution history of the Galaxy seems to be remarkably constant throughout the disk.However, the radial migration of stars, which follows a non-circular orbit across the Milky Ways spiral structure, causes mixing that makes the distribution of stellar parameters look uneven. Bovy also emphasized the importance of open science, sharing data and code related to their work. Like all SDSS data, the APOGEE spectra have been released publicly, and all their software pipelines and stellar models have also been made public. Coming next is an APOGEE-2 survey of the Southern sky, a copy of the instrument to be installed at the DuPont telescope in Chile.Afternoon Press Conference Dark Skies, Aliens, and the Multiverse (by Chris Faesi)Tuesday afternoon brought another press conference to the AAS 228th meeting, this one taking us beyond the benign realms of planets, stars, and

    Full Text Available The present study aimed at determining the effects of the interaction between afternoon aeration and stocking density of Nile tilapia on variables of water and soil quality, growth performance and effluent quality. The experiment was a 3 x 2 factorial randomized block design, with three stocking densities (8, 12 and 16 fish per tank or 43.5, 65.3, and 87.0 g m-3 under two mechanical aeration regimes, absence (control; three replicates and afternoon aeration (four replicates. The afternoon aeration was carried out from 12.00 a.m. up to 18.00 p.m. from the 3rd week until the end of the experiment. Except for the 16-fish tanks, the lowest concentrations of total ammonia nitrogen were found in the tanks with higher density of fish provided with afternoon aeration. Nitrite concentrations were lower in the 8-fish aerated tanks. In intensive system, the afternoon aeration of the fish culture water is an efficient management of water quality to remove gaseous ammonia and nitrite from water, but it is not appropriate to remove hydrogen sulfide from water.

    Understanding wind direction (WD) variability better is important for several reasons. Air pollution models need information about how variable wind direction is in different conditions (Davies and Thomson 1999). Accurate predictions of dispersion are important for human health and safety and allow for adaptation planning (Nagle et al. 2011). Other applications include horizontal diffusion, efficiency and fatigue of wind machines and air-sea interaction (Mahrt 2011). Most studies of wind direction variability have focused on nocturnal conditions because of greater variability in light winds. Modelling WD variability in transition periods when both mean wind speed and variance of the wind components are in a state of change can, however, also be very challenging and has not been the focus of earlier studies. The evening transitioning to the nocturnal boundary layer can play an important role in the diffusion process of pollutants and scalars emitted at surface and transported within the atmosphere. The Boundary Layer Late Afternoon and Sunset Turbulence (BLLAST) field campaign that took place in southern France in June and July 2011 focused on the decaying turbulence of the late afternoon boundary layer and related issues (Lothon et al. 2012). We analyse field measurements from BLLAST to investigate WD variability in the evening transition period. Standard deviations of horizontal wind direction fluctuations in the lowest 60 m of the boundary layer have been examined for dependence on mean wind speed, higher order moments and averaging time. Measurement results are interpreted using measured and idealized probability density functions of horizontal wind vectors. These are also used to develop analytical functions describing how WD variability depends on wind speed, variance and other controlling factors in the atmospheric boundary layer.

    A simple model for turbulence kinetic energy (TKE) and the TKE budget is presented for sheared convective atmospheric conditions based on observations from the Boundary Layer Late Afternoon and Sunset Turbulence (BLLAST) field campaign. It is based on an idealized mixed-layer approximation and a simplified near-surface TKE budget. In this model, the TKE is dependent on four budget terms (turbulent dissipation rate, buoyancy production, shear production and vertical transport of TKE) and only requires measurements of three available inputs (near-surface buoyancy flux, boundary layer depth and wind speed at one height in the surface layer) to predict vertical profiles of TKE and TKE budget terms.This simple model is shown to reproduce some of the observed variations between the different studied days in terms of near-surface TKE and its decay during the afternoon transition reasonably well. It is subsequently used to systematically study the effects of buoyancy and shear on TKE evolution using idealized constant and time-varying winds during the afternoon transition. From this, we conclude that many different TKE decay rates are possible under time-varying winds and that generalizing the decay with simple scaling laws for near-surface TKE of the form tα may be questionable.The model's errors result from the exclusion of processes such as elevated shear production and horizontal advection. The model also produces an overly rapid decay of shear production with height. However, the most influential budget terms governing near-surface TKE in the observed sheared convective boundary layers are included, while only second-order factors are neglected. Comparison between modeled and averaged observed estimates of dissipation rate illustrates that the overall behavior of the model is often quite reasonable. Therefore, we use the model to discuss the low-turbulence conditions that form first in the upper parts of the boundary layer during the afternoon transition and are only

    The afternoon Joule heating hot spot has been studied statistically by using the EISCAT Svalbard Radar (ESR) measurements at 75.4° Corrected Geomagnetic latitude (CGMLAT) and the OMNI solar wind data base. For a small subset of events, the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE) field-aligned current distributions have been available. The main results are as follows. Afternoon Joule heating hot spots are associated with high values of ionospheric electric fields and slightly enhanced Pedersen conductances. The Joule heating hot spot values are larger in summer than in winter, which can be explained by the higher Pedersen conductances during summer than winter. The afternoon Joule heating hot spots are located close to the reversals of the large-scale field-aligned current systems. The most common location is close to the Region 1/Region 2 boundary and those events are associated with sunward convecting F region plasma. In a few cases, the hot spots take place close to the Region 1/Region 0 boundary and then the ionospheric plasma is convecting antisunward. The hot spots may occur both during slow (450 km/s) speed solar wind conditions. During slow-speed solar wind events, the dominant interplanetary magnetic field (IMF) direction is southward, which is the general requirement for the low-latitude magnetic merging at the dayside magnetopause. During high-speed solar wind, also northward IMF conditions appear, but those are associated with large values of the IMF |By| component, making again the dayside magnetopause merging possible. Finally, the measured afternoon hot spot Joule heating rates are not a linear function of the solar wind energy coupling function.

  13. Rye kernel breakfast increases satiety in the afternoon - an effect of food structure

    Full Text Available Abstract Background The structure of whole grain cereals is maintained to varying degrees during processing and preparation of foods. Food structure can influence metabolism, including perceived hunger and satiety. A diet that enhances satiety per calorie may help to prevent excessive calorie intake. The objective of this work was to compare subjective appetite ratings after consumption of intact and milled rye kernels. Methods Two studies were performed using a randomized, cross-over design. Ratings for appetite (hunger, satiety and desire to eat were registered during an 8-h period after consumption of whole and milled rye kernels prepared as breads (study 1, n = 24 and porridges (study 2, n = 20. Sifted wheat bread was used as reference in both study parts and the products were eaten in iso-caloric portions with standardized additional breakfast foods. Breads and porridges were analyzed to determine whether structure (whole vs. milled kernels effected dietary fibre content and composition after preparation of the products. Statistical evaluation of the appetite ratings after intake of the different breakfasts was done by paired t-tests for morning and afternoon ratings separately, with subjects as random effect and type of breakfast and time points as fixed effects. Results All rye breakfasts resulted in higher satiety ratings in the morning and afternoon compared with the iso-caloric reference breakfast with sifted wheat bread. Rye bread with milled or whole kernels affected appetite equally, so no effect of structure was observed. In contrast, after consumption of the rye kernel breakfast, satiety was increased and hunger suppressed in the afternoon compared with the milled rye kernel porridge breakfast. This effect could be related to structural differences alone, because the products were equal in nutritional content including dietary fibre content and composition. Conclusions The study demonstrates that small changes in diet composition

    From a typically convective diurnal situation to a stably stratified nocturnal one, the atmospheric boundary layer (ABL) experiences the so-called afternoon and evening transition. This period is complex to study due to the presence of many different forcings, usually weak and opposite [1]. In this work, the transitional processes are studied by using 6-year data from permanent instrumentation at CIBA, a research center located in the Spanish Northern plateau. These measurements include particulate matter (PM) and turbulent records. Certain variables display a twin pattern in their time evolution for all the seasons, only differing in their absolute values. On the contrary, the air specific humidity behaves differently for each season, which is distinct to the results from a previous study at a different location [2]. Besides, a common pattern of increasing PM values near sunset is found, with a number of influences playing a role in PM concentrations: stability, turbulence and ABL thickness among others. In particular, the competing thermal and mechanical turbulent effects result in PM concentration reduction (settling on the ground or being advected) or increase, depending in each case on the specific season and particle group. Furthermore, the relative importance of the bigger PM (between 2.5 and 10 μm) is linked to the wind minimum around sunset, especially during summer.

    The purpose of this study was to characterize cerebrovascular responses to rowing exercise, investigating whether their diurnal variation might explain performance differences across a day. Twelve male rowers completed incremental rowing exercise and a 2000-m ergometer time trial at 07:00 h and 16:00 h, 1 week apart, while middle cerebral artery velocity (MCAv), cerebral (prefrontal), and muscular (vastus lateralis) tissue oxygenation and hemoglobin volume (via near-infrared spectroscopy), heart rate, and pressure of end-tidal CO2 (PET CO2) were recorded. MCAv was 20-25% above resting levels (68 ± 12 cm/s) during submaximal and maximal exercise intensities, despite PET CO2 being reduced during maximal efforts (down ∼ 0.5-0.8 kPa); thus revealing a different perfusion profile to the inverted-U observed in other exercise modes. The afternoon time trial was 3.4 s faster (95% confidence interval 0.9-5.8 s) and mean power output 3.2% higher (337 vs 347 W; P = 0.04), in conjunction with similar exercise-induced elevations in MCAv (P = 0.60) and reductions in cerebral oxygenation (TOI) (P = 0.12). At the muscle, afternoon trials involved similar oxygen extraction (HHb volume and TOI) albeit from a relatively lower total Hb volume (P rowing performance was better in the afternoon, but not in conjunction with differences in MCAv or exercise-induced differences in cerebral oxygenation.

    Hana Baklouti

    Full Text Available The purpose of this study was to examine the effect of active warm-up duration on short-term maximal performance assessed during Ramadan in the afternoon.Twelve healthy active men took part in the study. The experimental design consisted of four test sessions conducted at 5 p.m., before and during Ramadan, either with a 5-minute or a 15-minute warm-up. The warm-up consisted in pedaling at 50% of the power output obtained at the last stage of a submaximal multistage cycling test. During each session, the subjects performed two vertical jump tests (squat jump and counter movement jump for measurement of vertical jump height followed by a 30-second Wingate test for measurement of peak and mean power. Oral temperature was recorded at rest and after warming-up. Moreover, ratings of perceived exertion were obtained immediately after the Wingate test.Oral temperature was higher before Ramadan than during Ramadan at rest, and was higher after the 15-minute warm-up than the 5-minute warm-up both before and during Ramadan. In addition, vertical jump heights were not significantly different between the two warm-up conditions before and during Ramadan, and were lower during Ramadan than before Ramadan after both warm-up conditions. Peak and mean power were not significantly different between the two warm-up durations before Ramadan, but were significantly higher after the 5-minute warm-up than the 15-minute warm-up during Ramadan. Moreover, peak and mean power were lower during Ramadan than before Ramadan after both warm-up conditions. Furthermore, ratings of perceived exertion were higher after the 15-minute warm-up than the 5-minute warm-up only during Ramadan.The prolonged active warm-up has no effect on vertical jump height but impairs anaerobic power assessed during Ramadan in the afternoon.

    2016-01-01

    Dr. Ida Lystic is a gastroenterologist who recently began her new faculty position at the BEST (Byron Edwards and Samuel Thompson) Medical Center. After completing her MD degree at the prestigious Harvey Medical School (recently renamed the Harvey Provider School), she did her internal medicine residency and fellowship training at the OTHER (Owen T. Henry and Eugene Rutherford) Medical Center. Her morning in gastroenterology clinic was highlighted by: (1) being reprimanded by the clinic nurse manager for a patient who not only arrived early, before clinic had opened, but also neglected to schedule the anesthesiologist for his colonoscopy; (2) the continued challenges of LEGEND (also known as Lengthy and Excessively Graded Evaluation and Nomenclature for Diagnosis by her colleagues), the new electronic medical record system after the BEST discarded the SIMPLE (Succinct Input Making Patient's Lives Electronic) system; (3) a nurse's interruption of an office visit-once the egg timer on the examination room door ran out-because she had exceeded the allocated time for the appointment; and (4) her chairman's unanticipated arrival in the clinic to visit with the clinic nurse manager. In addition to seeing her patients, Dr. Lystic's afternoon is occupied by attending a LOST (Laboratory OverSight and Testing) Committee meeting and a visit from a wayfinding and signage specialist to depersonalize the doorpost plaques of the examination rooms. Her day ends with a demeaning email from her chairman regarding the poor results of the most recent patient satisfaction survey and being personally held accountable to develop solutions to improve not only her performance but also that of the clinic. Although Dr. Ida Lystic and the gastroenterology clinic at "the BEST Medical Center" are creations of the authors' imagination, the majority of the anecdotes mentioned in this essay are based on individual patients and their physicians, clinics in medical centers and their administration

    Adolescent maturation is associated with delays of the endogenous circadian phase. Consequently, early school schedules may lead to a mismatch between internal and external time, which can be detrimental to adolescent sleep and health. In parallel, chronotype is known to play a role in adolescent health; evening chronotype adolescents are at higher risk for sleep problems and lower academic achievement. In the summer of 2008, Kénogami High School (Saguenay, Canada) was destroyed by fire. Kénogami students were subsequently relocated to Arvida High School (situated 5.3 km away) for the 2008-2009 academic year. A dual school schedule was implemented, with Arvida students attending a morning schedule (0740-1305 h) and Kénogami students an afternoon schedule (1325-1845 h). This study aimed to investigate the effects of such school schedules and chronotype on sleep, light exposure, and daytime functioning. Twenty-four morning and 33 afternoon schedule students wore an actigraph during 7 days to measure sleep and light exposure. Academic achievement was obtained from school. Subjects completed validated questionnaires on daytime sleepiness, psychological distress, social rhythms, school satisfaction, alcohol, and chronotype. Overall, afternoon schedule students had longer sleep duration, lower sleepiness, and lower light exposure than morning schedule students. Evening chronotypes (E-types) reported higher levels of sleepiness than morning chronotypes (M-types) in both morning and afternoon schedules. Furthermore, M-types attending the morning schedule reported higher sleepiness than M-types attending the afternoon schedule. No difference was found between morning and afternoon schedule students with regard to academic achievement, psychological distress, social rhythms, school satisfaction, and alcohol consumption. However, in both schedules, M-type had more regular social rhythms and lower alcohol consumption. In summary, this study emphasizes that an early school

    Because of the dominant influence of surface solar heating on atmospheric boundary layer (ABL) flows, the character and even underlying theories of turbulence vary diurnally over the continents. While great strides have been made in our understanding of the stable boundary layers that prevail overnight, the period of transition from a convective daytime to a stable nighttime ABL remains a very challenging problem in no small part because of its inherently non-stationary nature and because both of the main forcings, wind stress and surface heat flux, tend to flag at this time of day. These underexplored topics motivated the Boundary Layer Late Afternoon and Sunset Turbulence (BLLAST) field experiment held in the summer of 2011 at the CNRS Laboratorie d'Aerologie in Campistrous, France. On three of the twelve intensive observational days of the experiment, three rawinsondes were launched simultaneously approximately 3 km apart throughout the afternoon transition in order to directly measure mesoscale horizontal divergence in the ABL and lower free troposphere. Using the assumption of incompressibility, the observed divergence is integrated and a vertical profile of mean vertical wind is derived for the lower troposphere. Although the magnitude of the inferred vertical winds are much larger than expected (of order 0.1 ms-1), the measurements do indicate a clear trend in afternoon subsidence giving way to evening uplift at the site, which is within ~10 km of the Pyrenees' foothills. The observed transition from low-level divergence to convergence was accompanied by a deep surface pressure minimum that fluctuated by nearly 300 Pa diurnally, and we propose that it is likely related to the reversal of the plain-mountain circulation across the region. The impact of such behavior on boundary layer growth and entrainment during the afternoon hours are discussed along with evidence of similar behavior observed elsewhere in mountainous terrain.

DESIGN AND SETTING: Nine healthy elderly subjects (4m, 5f, age range 74y-87y) each experienced both nap and no-nap conditions in two studies each lasting 17 days (14 at home, 3 in the laboratory). In the nap condition a 90-minute nap was enforced between 13:30 and 15:00 every day, in the no-nap condition daytime napping was prohibited, and activity encouraged in the 13:30-15:00 interval. The order of the two conditions was counterbalanced. PARTICIPANTS: N/A INTERVENTIONS: N/A MEASUREMENTS: Diary measures, pencil and paper alertness tests, and wrist actigraphy were used at home. In the 72 hour laboratory studies, these measures were augmented by polysomnographic sleep recording, continuous rectal temperature measurement, a daily evening single trial of a Multiple Sleep Latency Test (MSLT), and computerized tests of mood, activation and performance efficiency. RESULTS: By the second week in the "at home" study, an average of 58 minutes of sleep was reported per siesta nap; in the laboratory, polysomnography confirmed an average of 57 minutes of sleep per nap. When nap and no-nap conditions were compared, mixed effects on nocturnal sleep were observed. Diary measures indicated no significant difference in nocturnal sleep duration, but a significant increase (of 38 mins.) in 24-hour Total Sleep Time (TST) when nocturnal sleeps and naps were added together (psleep efficiency in the nap condition (pSleep Time (TST) by 48 mins. in the nap condition (peffects on Wake After Sleep Onset (WASO), delta sleep measures, or percent stages 1 & 2. Unlike the diary study, the laboratory study yielded no overall increase in 24-hour TST consequent upon the siesta nap regimen. The only measure of evening alertness or performance to show an improvement was sleep latency in a single-trial evening MSLT

    The decay of turbulence kinetic energy (TKE) and its budget in the afternoon period from midday until zero-buoyancy flux at the surface is studied in a two-part paper by means of measurements from the Boundary Layer Late Afternoon and Sunset Turbulence (BLLAST) field campaign for 10 intensive observation period days. Here, in Part 1, near-surface measurements from a small tower are used to estimate a TKE budget. The overall boundary layer characteristics and mesoscale situation at the site are also described based upon taller tower measurements, radiosoundings and remote sensing instrumentation. Analysis of the TKE budget during the afternoon transition reveals a variety of different surface layer dynamics in terms of TKE and TKE decay. This is largely attributed to variations in the 8 m wind speed, which is responsible for different amounts of near-surface shear production on different afternoons and variations within some of the afternoon periods. The partitioning of near-surface production into local dissipation and transport in neutral and unstably stratified conditions was investigated. Although variations exist both between and within afternoons, as a rule of thumb, our results suggest that about 50 % of the near-surface production of TKE is compensated for by local dissipation near the surface, leaving about 50 % available for transport. This result indicates that it is important to also consider TKE transport as a factor influencing the near-surface TKE decay rate, which in many earlier studies has mainly been linked with the production terms of TKE by buoyancy and wind shear. We also conclude that the TKE tendency is smaller than the other budget terms, indicating a quasi-stationary evolution of TKE in the afternoon transition. Even though the TKE tendency was observed to be small, a strong correlation to mean buoyancy production of -0.69 was found for the afternoon period. For comparison with previous results, the TKE budget terms are normalized with

    This study examines the characteristics of low-frequency variations (defined as decadal-scale changes) in summer (June-August) convective afternoon rainfall (CAR) activity over Taiwan during 1961-2012. Using 3-hourly rain gauge data, it was found that (1) the CAR frequency exhibits a secular trend and the 10-20 decadal oscillation, (2) the trend in CAR frequency is positive in northern Taiwan but negative in central and southern Taiwan, and (3) the CAR rate increased over most of the lower plains but decreased over the mountain range of Taiwan. Diagnoses using the Japanese ReAnalysis (JRA-55) data and surface observations indicate that the low-frequency variations in CAR frequency are closely associated with the variations in monsoon southwesterly winds over the South China Sea and island-wide sea breeze convergence. The regional low-level circulation changes are linked to sea surface temperature anomalies over the Niño-4 region and its 10-20 year (quasi-decadal) oscillation. Regarding the processes that change the CAR rate in the trending patterns, it was found that increases in the moisture flux convergence and the moist (conditional) instability over the lower plains together explain the stronger CAR events in the long run.

    Shifting cutting from morning to afternoon has been shown to increase the concentration of nonstructural carbohydrates in forages. We hypothesized that, compared with a total mixed ration containing timothy baleage and silage cut in the morning (a.m.-cut TIM), a total mixed ration containing timothy baleage and silage cut in the afternoon (p.m.-cut TIM) would improve animal performance and N use efficiency in mid-lactation Holstein cows due to enhanced supply of ruminal fermentable energy. The objective of this study was to compare the effects of p.m.- versus a.m.-cut TIM on milk yield, concentrations and yields of milk components, ruminal metabolism, and plasma concentrations of AA in mid-lactation Holstein cows. Ten (6 ruminally cannulated) primiparous cows averaging 139±13 d in milk and 550±56 kg of body weight, and 6 (2 ruminally cannulated) multiparous cows averaging 128±11 d in milk and 632±57 kg of body weight at the beginning of the experiment, were used in a crossover design. Each period lasted 21 d with 14 d for diet adaptation and 7 d for data and sample collection. The concentration of nonstructural carbohydrates (water-soluble carbohydrates plus starch) was numerically greater in the p.m.- versus the a.m.-cut TIM and averaged 13.2±1.06% and 12.2±1.13%, respectively. Treatment × parity effects were observed for milk urea N, feed efficiency, and milk N efficiency, whereas parity effects were observed for nutrient intake, milk yield, and plasma concentration of several essential and nonessential AA. Intakes of dry matter (19.3 versus 18.6 kg/d) and nonstructural carbohydrates (2.56 versus 2.31 kg/d), and yields of 4% fat-corrected milk (23.1 versus 22.2 kg/d), energy-corrected milk (25.0 versus 24.1 kg/d), milk fat (0.91 versus 0.88 kg/d), and milk protein (0.77 versus 0.73 kg/d) were all greatest with feeding p.m.-cut TIM. Milk yield (23.5 versus 22.7 kg/d) tended to increase in cows fed p.m.-cut TIM. The ruminal fermentation profiles and plasma

    We investigate a non-typical very low frequency (VLF) 1-4 kHz hiss representing a sequence of separated noise bursts with a strange "mushroom-like" shape in the frequency-time domain, each one lasting several minutes. These strange afternoon VLF emissions were recorded at Kannuslehto (KAN, ϕ = 67.74° N, λ = 26.27° E; L ∼ 5.5) in northern Finland during the late recovery phase of the small magnetic storm on 8 December 2013. The left-hand (LH) polarized 2-3 kHz "mushroom caps" were clearly separated from the right-hand (RH) polarized "mushroom stems" at the frequency of about 1.8-1.9 kHz, which could match the lower ionosphere waveguide cutoff (the first transverse resonance of the Earth-ionosphere cavity). We hypothesize that this VLF burst sequence could be a result of the modulation of the VLF hiss electron-cyclotron instability from the strong Pc5 geomagnetic pulsations observed simultaneously at ground-based stations as well as in the inner magnetosphere by the Time History of Events and Macroscale Interactions during Substorms mission probe (THEMIS-E; ThE). This assumption is confirmed by a similar modulation of the intensity of the energetic (1-10 keV) electrons simultaneously observed by the same ThE spacecraft. In addition, the data of the European Incoherent Scatter Scientific Association (EISCAT) radar at Tromsø show a similar quasi-periodicity in the ratio of the Hall-to-Pedersen conductance, which may be used as a proxy for the energetic particle precipitation enhancement. Our findings suggest that this strange mushroom-like shape of the considered VLF hiss could be a combined mutual effect of the magnetospheric ULF-VLF (ultra low frequency-very low frequency) wave interaction and the ionosphere waveguide propagation.

    Observations of turbulence are analysed for the afternoon and evening transition (AET) during the Boundary-Layer Late Afternoon and Sunset Turbulence (BLLAST) experimental field campaign that took place in Lannemezan (foothills of the Pyrenees) in summer 2011. The case of 2 July is further studied because the turbulence properties of the lower atmosphere (up to 300 m above ground level) were sampled with the Meteorological Mini Aerial Vehicle (M2AV) from turbulently mixed to stably stratified atmospheric conditions. Additionally, data from radiosoundings, 60 m tower and UHF wind profiler were taken together with the model results from a high-resolution mesoscale simulation of this case. Weak large-scale winds and clear-sky conditions were present on the studied AET case favouring the development of slope winds and mountain-plain circulations. It is found that during the AET the anisotropy of the turbulent eddies increases as the vertical motions are damped due to the stably stratified conditions. This effect is enhanced by the formation of a low-level jet after sunset. Finally, the comparison of the anisotropy ratio computed from the different sources of observations allow us to determine the most relevant scales of the motion during the AET in such a complex terrain region.

    The response to sub-maximal physical activity performed in the morning and late afternoon by individuals with different chronotypes was investigated. 22 participants filled out the Morningness-Eveningness Questionnaire and underwent a self-paced walking task that consisted of walking from the top to the bottom of a hill and back three times (1,836 meters, with a slope of 14.16%). The task was repeated twice: late afternoon (16:30) and early morning (08:30). Walking speed (time for completion in seconds), heart rate, and perceived exertion were measured during each task, with overall results given as a general descriptive analysis. Preliminary findings suggest that chronotype is likely to influence the responses to exercise, mostly with evening-types seeming at a disadvantage when performing a physical task in the morning. Individuals can be classified by circadian typology or chronotype, which is the propensity to be a morning-type, evening-type, or neither-type. The circadian typology, commonly referred to as being a morning person or an evening person or somewhere in between, is involved not only in the expression of physiological rhythms, but also in habits and lifestyles, such as sleeping patterns (Park, Matsumoto, Seo, & Shinkoda, 1999) that emerge especially during adolescence (Park, Matsumoto, Seo, Kang, & Nagashima, 2002) and remain throughout adult life (Koukkari & Sothern, 2006).

    2016-01-01

    This paper reviews the first part of the outcomes of the ORCA Saturday Afternoon Symposium 2014 dealing with 'caries epidemiology and community dentistry: chances for future improvements in caries risk groups'. After the caries decline in many countries, there are remaining pockets of higher caries levels, mostly in the primary dentition and/or linked to a low socio-economic status (SES). The review into the evidence of caries-preventive measures clearly points to the use of fluorides, especially toothbrushing with fluoridated toothpaste and collective measures such as water fluoridation. In contrast to several unsuccessful high-risk approaches, community and public health programmes seem to be able to ensure a population-wide access and compliance in risk groups. Their simple and evidence-based measures mostly combine regular plaque removal and fluoride applications via toothbrushing, at least for children and adolescents. For the future, the common risk factor approach which addresses associations between oral health, social deprivation, diet, hygiene, smoking, alcohol use and stress should lead to combined efforts with other community health and education specialists. Further engagement with public policy, community leaders and administration is needed in order to strengthen healthy choices and behaviour, e.g. in 'healthy' schools and kindergartens. It seems advisable that these population programmes also aim at improving upstream factors. PMID:26752628

    The seasons on Mars and Earth are anti-correlated at present: days are getting shorter and shadows are getting longer as autumn end sand the beginning of winter draws nearer in the martian southern hemisphere, just as the same is occurring in Earth's northern hemisphere. Long shadows are especially prominent in this high resolution view of mountains forming part of the central peaks of Hale Crater (left), a 136 kilometer-(85 mile)-diameter impact crater at 36oS, 37oW. The two pictures were taken simultaneously by the Mars Global Surveyor Mars Orbiter Camera on November 10, 2000. The sun illuminates the scene from the northwest (upper left)about 22o above the horizon. Knowing the sun angle and the length of the longest shadow (1.6 km; 1.0 mi), the height of the largest peak in the high resolution view (right) is about 630 meters (2,070 ft) above the crater floor. Sand dunes blanket the middle portion of the high resolution view, and small gullies--possibly carved by water--can be seen on the slopes of some of the peaks at the upper left. Winter in the southern hemisphere will begin in mid-December 2000. The high resolution view covers an area 3 km (1.9 mi) wide at a full-resolution scale of 3 meters (9.8 ft) per pixel.

If you said Wikipedia, youre not alone. For many people, Wikipedia is the primary source of information about astronomy and science. However, many Wikipedia articles about science topics are incomplete or missing, and women are underrepresented among scientists with biographies.To address this, the AAS Astronomy Education Board teamed up with the Wiki Education Foundation to host an edit-a-thon as part of the Wikipedia Year of Science. More than forty attendees spent the better part of three hours working through tutorials, creating new articles, and editing existing ones. The session was generously sponsored by the Simons Foundation.The Year of Science initiative seeks to bring Wikipedia editing skills to the classroom and help new editors find sustainable ways to contribute to Wikipedia in the long term. Anybody can create a free account and start editing!As a first-time Wikipedia contributor, I took the time to go through nearly all the tutorial exercises and familiarize myself with the process of editing a page. I decided to flesh out one section in an existing page about asteroseismology. Others created biography pages from scratch or selected various astronomical topics to write about. To me, the editing process felt like a cross between writing a blog post and a journal article, in a hack day type environment. Working through the tutorial and some examples renewed my empathy for learners who are tackling a new skill set for the first time. A full summary of our contributions is available. Altogether, we contributed nearly 13,000 words to 44 articles.#aas228 @WikiEducation pic.twitter.com/Xj837wjuDJ AAS Executive Office (@AAS_Office) June 15, 2016The Limits of Scientific Cosmology: The Way Forward (by Gourav Khullar)After the town-hall with an open mic that raised exceptional questions in the morning, some of the pioneers of the field of scientific cosmology were here with their concluding remarks about the future of the field. John Carlstrom laid down the pipeline for future surveys that not only provide us with interesting constraints on current physics, but give us the opportunity to test new physics. He discussed the CMB, galaxy cluster growth, the Hubble constant and Baryonic Acoustic oscillations as parameters that would define our model of the universe cohesively in the future. The importance of facilities like LSST, SKA, DESI, CMB-S4 were discussed, and Carlstrom emphasized that over the next two decades these fantastic machines will decide the fate of scientific cosmology. Leonard Susskind followed this up with a theoretical framework of how the ideas of inflation and vacuum energy could lead to our understanding of whether String Theory could be the correct theory of the universe. Love the yellow submarine analogy by Prof. Susskind #aas228 pic.twitter.com/sbPwjgdsg9 Jesus Salas (@TheSource007) June 15, 2016He touched upon multiverses with his analogy of a submarine floating in a sea with just the right amount of buoyancy balancing gravity a multiverse can have universes with different parameterized cosmological constants! Moreover, in Susskinds opinion, the only true limit that inhibits our understanding of the features of our universe beyond the cosmic event horizon was the event horizon of an event or phenomena. Jim Peebles concluding this mesmerizing series of talks with his opinions on how physics ought to be direct and assertive with its theories, and should take pride in its explanatory power (or should it?).Peebles: expect surprises and think outside the box yes! #aas228 Kevin Schawinski (@kevinschawinski) June 15, 2016His comparison of local vs. high-redshift cosmology in terms of scales of problems was outstanding, and he encouraged the audience and the community to keep an open mind. After all, in Sean Carrolls words, we do live in a preposterous universe, and the time is almost right to explain it all.This The Limits of Scientific Cosmology series at #aas228 has been absolutely fantastic. @AAS_Office please put videos on youtube! Kevin Schawinski (@kevinschawinski) June 15, 2016Press Conference Black Holes and Gamma-Ray Bursts (by Susanna Kohler)The final press conference of the meeting covered three topics from the categories of black holes and gamma-ray bursts.Fred Rasio (CIERA/Northwestern University) opened the conference with a discussion of how the systems that LIGO detected might have formed. There are two primary models for how these black-hole binaries are created. In the first, they start out as binary systems of two massive stars. If the binary survives the process of both stars collapsing into black holes, then a binary black hole system results.Rasio focused on the second theory, in which that black holes are formed in dense stellar clusters. These black holes then sink (via dynamical friction) to the centers of the clusters like dust particles settling on the floor of a room, where they form binaries in a black hole mosh pit eventually getting kicked out of the cluster by dynamical interactions. You can read more about their research in the press release here.Rasio presents a pretty awesome animation of this black hole mosh pit. https://t.co/AkewctI7uK#aas228 astrobites (@astrobites) June 15, 2016The effects of a spinning black hole on the spacetime around it. [J.P. Eekels J.M. Overduin]Next up was Richard Henry (Johns Hopkins University), who spoke about the internal structure of spinning black holes (known as Kerr black holes). Because no light can escape from black hole interiors, we cant learn whats in them via observation. Instead, we rely on mathematical descriptions of what their interiors look like. Henry and collaborators have developed a new coordinate-invariant depiction of the structure of black holes that reframes how we think about visualize their interiors. More information can be found in their paper here.The final press conference presentation was given by Maria Dainotti (Stanford University) on the subject of using gamma-ray bursts (GRBs) as standard candles. Standard candles are astrophysical sources that have known luminosities. We can use the light we observe from standard candles to estimate their distance, making them useful tools for testing cosmological models.Type Ia supernovae (which always have roughly the same source brightness) are a typical example of a standard candle, and led to the discovery of dark energy in the 1990s. But if GRBs could be used in a similar way, they would be a much more powerful tool: theyre visible out to significantly further distances because theyre so bright. Dainotti and collaborators are analyzing a subset of GRBs from Swift observations that they term gold GRBs. By examining the correlations between parameters of these gold GRBs, Dainotti attempts to understand whether they can be used as standard candles.Plenary Session From the First Stars and Galaxies to the Epoch of Reionization: 20 Years of Computational Progress (by Gourav Khullar)Mike Normans (University of California San Diego) plenary talk concluded the AAS Plenary sessions with a treatise on the current generation of simulations that aim to characterize the first stars and galaxies that formed in the Universe. Last plenary talk for today. #aas228pic.twitter.com/uTaWt6Qi00 Daniel Caton (@DanielCaton) June 15, 2016Mike has been working in the field for a long time, and his collaborators work on the Enzo simulations is very well known. This talk was centered around some of the latest Enzo results, with a special emphasis on tracking down the Epoch of Reionization with a new series of runs called the Renaissance simulations. These runs focused on the most primeval galaxies ever formed in a cosmological box. Mikes team uses Blue Waters, USAs fastest supercomputer, situated in NCSA at Urbana-Champaign, Illinois (which also manages the large datasets coming out of the Dark Energy Survey!). The talk described the initial dark matter and gas dynamics along with a dark energy-supported metric evolution using simulations of a cosmic box that was the initial universe. The linear fluctuations of this initial universe formed the first stars (called Population III stars in the astrophysics community) from hydrogen and helium generated in the Big Bang. Mike and his team established a catalogue of these first stars, and parameterized these into a function that modeled how these stars became the first galaxies, and eventually into the larger galaxies from the merger of smaller galaxy halos. Michael Norman shows some new computational simulations of ionization in the early Universe. #aas228pic.twitter.com/pzXPMTgnIs Meredith Rawls (@merrdiff) June 15, 2016The statistics of these first galaxies (from the above mentioned Renaissance simulations) show that the first galaxies formed around a redshift of z = 20, roughly around the same time as the first stars, and way before the actual epoch of reionization (at z ~ 7, the concept is described here). The simulation results extended this evolution to the epoch of reionization and put interesting constraints on observations of this epoch, when we can actually see the ionized gas from this epoch in our observations. Investigations are ongoing, and Mike Normans team is positive that the Enzo simulations are here to stay for a long time, challenging and collaborating with observations along the way.

However, many Wikipedia articles about science topics are incomplete or missing, and women are underrepresented among scientists with biographies.To address this, the AAS Astronomy Education Board teamed up with the Wiki Education Foundation to host an edit-a-thon as part of the Wikipedia Year of Science. More than forty attendees spent the better part of three hours working through tutorials, creating new articles, and editing existing ones. The session was generously sponsored by the Simons Foundation.The Year of Science initiative seeks to bring Wikipedia editing skills to the classroom and help new editors find sustainable ways to contribute to Wikipedia in the long term. Anybody can create a free account and start editing!As a first-time Wikipedia contributor, I took the time to go through nearly all the tutorial exercises and familiarize myself with the process of editing a page. I decided to flesh out one section in an existing page about asteroseismology. Others created biography pages from scratch or selected various astronomical topics to write about. To me, the editing process felt like a cross between writing a blog post and a journal article, in a hack day type environment. Working through the tutorial and some examples renewed my empathy for learners who are tackling a new skill set for the first time. A full summary of our contributions is available. Altogether, we contributed nearly 13,000 words to 44 articles.#aas228 @WikiEducation pic.twitter.com/Xj837wjuDJ AAS Executive Office (@AAS_Office) June 15, 2016The Limits of Scientific Cosmology: The Way Forward (by Gourav Khullar)After the town-hall with an open mic that raised exceptional questions in the morning, some of the pioneers of the field of scientific cosmology were here with their concluding remarks about the future of the field. John Carlstrom laid down the pipeline for future surveys that not only provide us with interesting constraints on current physics, but give us the opportunity to test new physics. He discussed the CMB, galaxy cluster growth, the Hubble constant and Baryonic Acoustic oscillations as parameters that would define our model of the universe cohesively in the future. The importance of facilities like LSST, SKA, DESI, CMB-S4 were discussed, and Carlstrom emphasized that over the next two decades these fantastic machines will decide the fate of scientific cosmology. Leonard Susskind followed this up with a theoretical framework of how the ideas of inflation and vacuum energy could lead to our understanding of whether String Theory could be the correct theory of the universe. Love the yellow submarine analogy by Prof. Susskind #aas228 pic.twitter.com/sbPwjgdsg9 Jesus Salas (@TheSource007) June 15, 2016He touched upon multiverses with his analogy of a submarine floating in a sea with just the right amount of buoyancy balancing gravity a multiverse can have universes with different parameterized cosmological constants! Moreover, in Susskinds opinion, the only true limit that inhibits our understanding of the features of our universe beyond the cosmic event horizon was the event horizon of an event or phenomena. Jim Peebles concluding this mesmerizing series of talks with his opinions on how physics ought to be direct and assertive with its theories, and should take pride in its explanatory power (or should it?).Peebles: expect surprises and think outside the box yes! #aas228 Kevin Schawinski (@kevinschawinski) Ju

Risa set the stage with an elaborate description of the current accepted facts in the era of precision cosmology including the standard model of concordance cosmology, described by seven parameters and an accepted Lambda-CDM paradigm (with a cosmological constant and cold dark matter). The talk stressed on the fact that all these parameters are understood to a percent order precision, which is a remarkable deviation from the time in 1990s when according to Risa, Alan Guth never thought that any of these numbers could be measured precisely!Risa Wechsler describing our current constraints on what Dark Matter could constitute.Joseph Silk discussing limits on cosmological parameters.The CMB measurements, Big Bang Nucleosynthesis estimates and galaxy clustering statistics all contribute to locking down the description of our universe. She emphasized on the tensions between different probes to measure expansion rate H0 of the universe, and small scale predictions of cold dark matter simulations, but she is hopeful that these shall be resolved eventually. Joe Silk followed this up with his interpretation of trying to understand our place in the universe and placing limits on different parameters and scales that we measure, ranging from star masses to dark energy scale estimates.By invoking the anthropic principle, Silk pointed out that perhaps multiverses could offer a potential solution to certain causes of concern in our current models. The future looked good, and according to Silk, a better characterization of non-gaussianities using powerful simulations and precise CMB measurements is the way to go.The Limits of Scientific Cosmology: Normal Science in a Multiverse(by Nathan Sanders)Slotted into the contrarian slot of this special session on the limits of cosmology, Sean Carroll (Caltech) made a powerful argument for the normalcy of the multiverse prediction of inflationary and other theories of cosmology. While other scientists, including earlier speakers in the session, suggested that the intense difficulty of collecting data directly testing the multiverse prediction disqualifies it as a scientific theory, Carroll argued that this is no different from the reality of the scientific process applied generally. He combats the absolutist interpretation of Karl Poppers writing on demarcation, which implies that only imminently-falsifiable theories qualify as scientific. Instead, he points us to abduction as the fundamental motive of science, the idea that we seek to move towards the model that best explains the available evidence, closely related to Bayes theorem. He acknowledged that we may never collect enough evidence for our credence in the multiverse to converge to one, and yet it may definitely be true. While he puts his own credence in the multiverse at about 50%, Carroll concludes that we should not reject the possibility of the multiverse out of hand solely on the basis of philosophical arguments. Surprisingly, Carroll also comments that evidence can include both data and theory, specifically new interpretations of old ideas and new predictions. For example, Einstein did not make new observations of the precession of Mercury to lend credence (in the scientific sense) to his then-new theory of general relativity. Instead, he applied his theory for the

    Full Text Available Considerando o Maio de 68 uma abreviação do tempo histórico que condensa várias experiências do político, este trabalho procura traduzir o passado no presente, no sentido benjaminiano da comemoração. Comemorar uma data significa nascer em cada novo aniversário. Procura-se mostrar uma verdadeira mutação do imaginário coletivo que desconhece a transcendência do poder e a eficácia de suas leis. O movimento não se pautou nem pelo ideário da "sociedade do espetáculo" nem por suas leis. Reunindo o poético e o político, afirmou a verdade triunfante do desejo. Seja compreendido como levante, revolta ou revolução, pode-se dizer ter sido um "ensaio" da revolução que, pela não violência, por uma generosa cultura do cosmopolitismo e do internacionalismo, indicou a passagem do "socialismo científico" ao socialismo, finalmente possível - o utópico. Reflete ainda sobre os ícones revolucionários e suas ressignificações, estabelecendo a diferença entre o herói mítico e o herói histórico, entre Lenin ou Trotsky, Rosa Luxemburgo ou Fidel e o mítico Guevara.Considering May as an abreviation of the historical time which concentrates lots of expeiriences in politics, this text tries to translate the past into present, in the benjaminian sense of celebration. To celebrate a date is to be born in each birthday. It is intended to show true mutations of colective imaginary which doesn't know the transcendency of the power and the efficiency of its laws. This movement was neither guided by the set of ideas of "a show society" or its laws. Gathering together the politician and the politician, it assured the truth of the desire. Whereas it is understood as insurration, rebelion or revolution, it can be said to be a "reharsal " of the revolution , which using no violence, generous culture of cosmopolitism , and intencionalism, has indicated the way from the "scientific socialism ' to the socialism which was possible to be stablished, the Utopic. This text also reflects about some revolutionary icons and their new meanings , setting the difference between the mythical hero and the historical hero, between Lenin or Trotsky, Rosa Luxemburgo or Fidel and the myth Guevara.

    Focussing on June 14th, 1936 when Mann visited Freud to read him the speech he had delivered in Vienna in celebration of Freud's 80th birthday, the paper investigates the "less than simple" relation between the two men. It shows how they gradually approached each other and then in 1929 entered into direct contact after Mann had publicly underlined Freud's relevance for his project "psychology and myth". Some traces of personal ambivalence contained in the 1936 lecture are highlighted. The author discusses the potential significance for both men of Freud's response to Mann's speech where he interpreted aspects of Napoleon's life as based on his identification with the biblical Joseph in order to surpass his elder brother. Finally it is considered whether Mann's contact with Freud may have helped him to cope with the trauma of the early loss of his father.

  7. Big Bang Day : Afternoon Play - Torchwood: Lost Souls

    2008-01-01

    Martha Jones, ex-time traveller and now working as a doctor for a UN task force, has been called to CERN where they're about to activate the Large Hadron Collider. Once activated, the Collider will fire beams of protons together recreating conditions a billionth of a second after the Big Bang - and potentially allowing the human race a greater insight into what the Universe is made of. But so much could go wrong - it could open a gateway to a parallel dimension, or create a black hole - and now voices from the past are calling out to people and scientists have started to disappear... Where have the missing scientists gone? What is the secret of the glowing man? What is lurking in the underground tunnel? And do the dead ever really stay dead? Lost Souls is a spin-off from the award-winning BBC Wales TV production Torchwood. It stars John Barrowman, Freema Agyeman, Eve Myles, Gareth David-Lloyd, Lucy Montgomery (of Titty Bang Bang) and Stephen Critchlow.

  10. Gas Breakdown, Low Current diffuse discharges, Townsend's theory: A Friday afternoon experiment

    Science.gov (United States)

    Petrovic, Zoran

    2013-09-01

    Numerous aspects of the ``standard model'' of gas breakdown have been addressed in the past 20 years by Art Phelps and his coworkers. First, his studies of excitation coefficients were carried out in the Townsend regime where electric field is quasi uniform so swarm like conditions prevail. These studies have been extended to very high E/N where non-hydrodynamic effects were to be observed but were overshadowed in most cases by fast neutral excitation. Absolute calibration of emission provided a basis to obtain fast neutral cross section sets. This work necessarily overlapped with the left hand side of the Paschen curve and in extension of an ill fated data gathering experiment a review was made of all the processes that contribute to the secondary electron emission. It was shown that, if one includes all the processes, it is possible to fit the available breakdown data, Paschen curves and effective electron yields by binary collision data obtained in separate experiments. While performing measurements in the low current diffuse (Townsend) regime one can find negative differential resistance and oscillations. Both were explained by taking detailed information on properties of particles close to the cathode and small perturbations to the local field by the growing space charge. Last but not the least Phelps managed, with his coworkers to provide a phenomenology and predictions of the anomalously broadened profiles often observed in various discharges. In all those cases deep knowledge of atomic and molecular physics and of gas discharges were combined with best available data to produce quantitative (quantitative, quantitative) agreement with experiments.

    2010-01-01

    We did it! The first high-energy collisions were achieved at 13.06 today at all four points of the LHC ring. Collisions occurred after a few attempts at injecting and ramping beams in the morning. Before the collisions, there was a mixture of excitement, expectation, fear and apprehension in the CERN Control Centre. Nobody had ever attempted to make two proton beams collide at 3.5 TeV before. Only Nature produces collisions like this routinely, in the processes that yield cosmic radiation, but in a way that makes it very difficult to extract meaningful data.

    Bing, R K

    1997-03-01

    Using published works, archival correspondence, interviews with contemporaries, and historical commentary, an imagined conversation is presented between Eleanor Clarke Slagle (1871-1942) and three of her actual contemporaries. As a founder of the National Society for the Promotion of Occupational Therapy (later to become the American Occupational Therapy Association [AOTA] and a past-president and executive secretary of AOTA for 21 years, Slagle came in contact with a host of therapists as well as men and women who influenced her and the occupational therapy profession, most particularly Julia Lathrop, Adolf Meyer, William Rush Dunton, Jr., and Ida Sands. Emphasis is placed on some of her early life experiences; Hull House; and the evolution of the occupational therapy belief system, including occupations, curative work, and spiritual rehabilitation (i.e., self-respect, interests, ambition, happiness, economic usefulness, success). Special attention was taken to reflect Slagle's typical use of language and the vernacular of the mid-1930s. Extensive study was undertaken, through reading Slagle's published works, to remain true to her use of language.

    The four Magnetospheric Multiscale mission spacecraft were launched from the Cape Canaveral Air Force Station early on March 13 2015 into an elliptical orbit with apogee of 12 Re in the dawn magnetosphere. Until July 9, the spacecraft orbited the Earth in a string of pearls configuration exploring the near-Earth tail with a brief exit of the magnetosphere when CME arrived at Earth. On July 9, the four spacecraft were stationed in a tetrahedral formation with separations of 160 km. During the period ending December 1, the four spacecraft drift around to noon, exploring the magnetopause with a well formed tetrahedron, with sides as short as 10 km allowing us to study the magnetic and electric current structure of the magnetopause. This structure is complex. There is large-scale reconnection often resulting in the formation of fluxropes connected to the magnetosphere such as FTEs. Consistent with earlier measurements, there are often thin tubes of magnetic field crossing the current layer. In this survey we compare the MMS observations with the observed earlier by ISEEs 1 and 2 spacecraft.

    Empirical evidence from sequential auctions shows that prices of identical goods tend to decline between rounds. In this paper, I show how expectations-based reference-dependent preferences and loss aversion can rationalize this phenomenon. I analyze two-round sealed-bid auctions with symmetric bidders having independent private values and unit demand. Equilibrium bids in the second round are history-dependent and subject to a "discouragement effect": the higher the winning bid in the first a...

    This study compared satiety after high protein pasta (16 g protein, 6 g fiber), high fiber pasta (11 g protein, 8 g fiber) or control pasta (11 g protein, 6 g fiber) in a randomized, placebo-controlled, double-blind crossover trial. Participants were 36 healthy and men and women from the University of Minnesota campus. Fasted men and women ate calorie controlled, but macronutrient different pastas at 12:00 pm along with 500 mL of water. The primary outcome was satiety assessed by Visual Analogue Scales at 0, 15, 30, 45, 60, 90, 120, and 180 min daily after consuming the pastas. Secondary outcomes were calories consumed at an ad libitum snack at 3:00 pm, calories from food intake, gastrointestinal tolerance, and palatability. No differences were found among the pasta treatments for satiety, snacking, or gastrointestinal tolerance. Men ate significantly more calories for the rest of the (P = 0.007) after the high protein pasta versus the high fiber pasta (1701 ± 154 compared with 1083 ± 154) with control pasta being intermediate to the other treatments. No significant differences were found for gastrointestinal tolerance, but the palatability ratings showed the high protein pasta was less tasty (P = 0.03) and less pleasant (P = 0.01) than the other 2 pastas. Satisfaction was positively associated with pleasantness and negatively associated with aftertaste. Our results do not support the idea that high protein or high fiber pasta produces a greater satiety response compared to pasta with lower amounts of either nutrient. It is likely that since pasta is already a very satiating food, the subjects were unable to differentiate between the 3 conditions.

    2000-09-01

    Young adult male rats, maintained either in an LD 12 : 12 or in continuous illumination (LL) for one week, were given a single injection of 25 g melatonin/100 g body wt or ethanolic-saline (control) at 17.00 h. Animals from each group were sacrificed at 11.00 h on the following day. The activity of two important steroidogenic enzymes, 17-hydroxysteroid dehydrogenase (17-HSD) and Δ5-3-hydroxysteroid dehydrogenase (Δ5-3-HSD), and serum concentrations of testosterone, were measured following highly specific and sensitive spectrophotometric techniques and RIA, respectively. A significant decrease in the activity of both the steroidogenic enzymes was noted in the testes of melatonin-treated rats maintained under normal light-dark schedules, but this response was found to be lacking in the LL rats. However, no significant changes in the level of serum testosterone were noted in either group of melatonin-treated rats from the values in respective groups of ethanolic saline-administered LD and LL rats. Exposure of ethanolic saline-injected rats to continuous light also did not cause any change in the steroidogenic activity of the testis from those in LD rats. The study indicates that continuous light as such does not affect the endocrine function of testis but abolishes suppressive effects of melatonin on the steroidogenic activity of the testis in rat.

    Full Text Available Determinaram-se procedimentos para estimar produção diária de leite usando controles da manhã (AM ou da tarde (PM e comparar sistemas de controle para previsão da produção de leite em 305 dias usando várias combinações de controles AM e PM. Utilizaram-se 20.328 produções do dia de controle de 1.516 lactações de vacas ordenhadas duas vezes ao dia, em 96 rebanhos supervisionados pela Associação dos Criadores de Gado Holandês de Minas Gerais e registradas no período de 2000 a 2003. Sete procedimentos foram usados para estimação da produção diária. Correlações entre produções observada e estimada, médias e desvios-padrão das diferenças entre elas e desvios-padrão das produções estimadas foram os critérios para comparação de procedimentos. As estimativas obtidas com a ordenha da manhã foram mais acuradas do que as obtidas com as da ordenha da tarde. O procedimento em que se incluiu uma regressão para cada classe de intervalo de ordenhas e uma regressão sobre dias em lactação foi o selecionado para estimação da produção diária. Quatro sistemas para previsão da produção de leite em 305 dias foram comparados. Os sistemas com alternância mensal dos controles AM-PM apresentaram melhores resultados do que aqueles em que se utilizaram somente o controle AM ou somente PM. As correlações entre produção estimada e observada foram 0,99 e 0,97, respectivamente, para os primeiros e os últimos sistemas. Alternância dos controles AM-PM, iniciando-se com o controle AM, foi o sistema mais acurado de estimação.Procedures to estimate daily yield from either morning (AM or evening (PM test weighings and to compare different systems of testing for accuracy of predicting 305-day milk yield using various combinations of AM and PM production records were determined. Data of 20,328 test-day records of 1,516 cows milked twice-a-day, from 96 Holstein Dairy Cattle Association herds in Minas Gerais State and recorded from 2000 to 2003. Seven procedures were used to estimate daily yields. Comparisons were made on the basis of correlations between true and estimated daily yields, average difference between the estimated and actual values and also the variances of differences. Morning weighings predicted daily yield more accurately than evening weighings. The procedure which included a regression for each milking interval class and a regression on days in milk were selected for estimation of daily yields. Four systems for predicting 305-day milk yield were compared. Alternating AM-PM testing systems on monthly frequency showed better results than testing always in the AM or always in the PM.

    In the dialogue What Is Music? between Carl Dahlhaus and Hans Heinrich Eggebrecht, music is defined as a "mathematized emotion" or an "emotionalized 'mathesis'". As emphasized by Marija Bergamo, this is the way of underlining its equal and unavoidable constitution, based on emotion and rational organization in the time dimension. So, Marija Bergamo is continuously searching for those music determinants in a musical work as an "autonomous aesthetic fact", whose base and real essence lie "withi...

  3. Diurnal Dependence of Growth Responses to Shade in Arabidopsis: Role of Hormone, Clock,and Light Signaling

    Romina Sellaro; Manuel Pacín; Jorge J. Casal

    2012-01-01

    We investigated the diurnal dependence of the hypocotyl-growth responses to shade under sunlight-night cycles in Arabidopsis thaliana.Afternoon shade events promoted hypocotyl growth,while morning shade was ineffective.The Ihy-D,elf3,lux,pif4 pif5,toc1,and quadruple della mutants retained the response to afternoon shade and the lack of response to morning shade while the Ihy cca 1 mutant responded to both morning and afternoon shade.The phyB mutant,plants overexpressing the multidrug resistance-like membrane protein ABCB19,and the iaa17/axr3 loss-of-function mutant failed to respond to shade.Transient exposure of sunlight-grown seedlings to synthetic auxin in the afternoon caused a stronger promotion of hypocotyl growth than morning treatments.The promotion of hypocotyl growth by afternoon shade or afternoon auxin required light perceived by phytochrome A or cryptochromes during the previous hours of the photoperiod.Although the ELF4-ELF3-LUX complex,PIF4,PIF5,and DELLA are key players in the generation of diurnal hypocotyl-growth patterns,they exert a minor role in the control of the diurnal pattern of growth responses to shade.We conclude that the strong diurnal dependency of hypocotyl-growth responses to shade relates to the balance between the antagonistic actions of LHY-CCA1 and a light-derived signal.

  4. Influence of trans-boundary biomass burning impacted air masses on submicron particle number concentrations and size distributions

    2014-08-01

    Submicron particle number concentration (PNC) and particle size distribution (PSD) in the size range of 5.6-560 nm were investigated in Singapore from 27 June 2009 through 6 September 2009. Slightly hazy conditions lasted in Singapore from 6 to 10 August. Backward air trajectories indicated that the haze was due to the transport of biomass burning impacted air masses originating from wild forest and peat fires in Sumatra, Indonesia. Three distinct peaks in the morning (08:00-10:00), afternoon (13:00-15:00) and evening (16:00-20:00) were observed on a typical normal day. However, during the haze period no distinct morning and afternoon peaks were observed and the PNC (39,775 ± 3741 cm-3) increased by 1.5 times when compared to that during non-haze periods (26,462 ± 6017). The morning and afternoon peaks on the normal day were associated with the local rush hour traffic while the afternoon peak was induced by new particle formation (NPF). Diurnal profiles of PNCs and PSDs showed that primary particle peak diameters were large during the haze (60 nm) period when compared to that during the non-haze period (45.3 nm). NPF events observed in the afternoon period on normal days were suppressed during the haze periods due to heavy particle loading in atmosphere caused by biomass burning impacted air masses.

  5. Atmospheric turbidity over Kathmandu valley

    Science.gov (United States)

    Sapkota, Balkrishna; Dhaubhadel, Rajan

    The atmosphere of Kathmandu Valley has been investigated by using Sunphotometer and Nephelometer during the pre-monsoon period of 1999. The atmospheric turbidity parameters (extinction coefficient for 500 nm wavelength τAG and Angstrom coefficient β) are found high in the morning and show decreasing trends from morning to late afternoon on average. Vertical dispersion of pollutants and increasing pollutant flushing rate by increasing wind speed from morning to late afternoon is the cause for this decreasing trend of turbidity over the valley. Being surrounded by high hills all around the valley, horizontal exit of pollutants without vertical dispersion is not possible. The scattering coefficient bscat of aerosols in ground level troposphere is also found high in the morning, which decreases and becomes minimum during afternoon. During late afternoon, bscat again shows a slightly increasing trend. The reason is the increasing vehicular emission during late afternoon rush period. The average values of Angstrom exponent α, β, τAG and bscat are found to be 0.624±0.023, 0.299±0.009, 0.602±0.022 and 0.353±0.014 km -1, respectively. About 76.8% of the observed values of β lie above 0.2 indicating heavy particulate pollution in the valley. A comparison of observed values of turbidity parameters with other major cities of the world shows that Kathmandu is as polluted as cities like Jakarta, Kansas, Beijing, Vienna, etc.

  6. Work-family conflict, emotional exhaustion, and displaced aggression toward others: the moderating roles of workplace interpersonal conflict and perceived managerial family support.

    2015-05-01

    Taking a resource-based self-regulation perspective, this study examined afternoon emotional exhaustion as a mediator linking the within-person relations between morning work-family conflict and later employee displaced aggression in the work and family domains. In addition, it examined resource-related contextual factors as moderators of these relations. The theoretical model was tested using daily diary data from 125 employees. Data were collected at 4 time points during each workday for 3 consecutive weeks. Multilevel modeling analysis showed that morning family-to-work conflict was positively related to afternoon emotional exhaustion, which in turn predicted displaced aggression toward supervisors and coworkers in the afternoon and displaced aggression toward family members in the evening. In addition, morning workplace interpersonal conflict exacerbated the impact of morning work-to-family conflict on afternoon emotional exhaustion, whereas perceived managerial family support alleviated the impact of morning family-to-work conflict on afternoon emotional exhaustion. These findings indicate the importance of adopting a self-regulation perspective to understand work-family conflict at work and its consequences (i.e., displaced aggression) in both work and family domains.

    Full Text Available The objective of this work was to examine the effect of heat stress on glucose and pH values in blood of high-yielding dairy cows in the early stage of lactation, as well as to determine whether the changes in these parameters are interdependent under such conditions. An experiment was performed on high-yielding dairy cows during the summer and the spring periods. Forty cows were selected, twenty each for the two periods under investigation. In the course of the experiment, the temperature humidity index (THI was determined for the entire period of investigations, and then also the average daily THI, nightmorning THI (average value of hourly THI measured from 22h on the previous day until 10h of the current day, as well as the day-night THI (average value of hourly THI measured during the period from 10h to 22h of the current day. The pH and glucose concentration were determined in blood samples taken in the morning and afternoon of days 30, 60, and 90 of lactation during the spring and summer periods of the investigations. Based on the results for the THI, it was established that the animals were not exposed to the effect of extreme heat stress during the spring period of investigations, while they were periodically exposed to moderate but also extreme heat stress during the summer, in particular in the afternoon hours. It can be concluded from the results obtained for the blood pH that the cows were in respiratory alkalosis during the summer in the morning and afternoon hours on day 30, in the afternoon hours of days 60 and 90 of lactation, as well as in the afternoon on day 90 of lactation during the spring period of investigations. During the summer period, there were no statistically significant differences between the pH value determined in the morning and afternoon hours on day 30 of lactation, while the pH value was significantly higher in the afternoon hours than in the morning hours on days 60 and 90 of lactation. There were no

(1) The DDAs can be classified into two broad categories, i.e., unstructured and structured DDAs. The unstructured DDAs are mainly distributed in the morning and afternoon, but the structured DDAs predominantly occurred around the magnetic local noon (MLN). (2) The unstructured DDAs observed in morning and afternoon present obviously different properties. The afternoon ones are much stable and seldom show pulsating property. (3) The DDAs are more easily observed under geomagnetically quiet times. (4) The structured DDAsmainly show patchy, stripy, and irregular forms and are often pulsating and drifting. The drifting directions are mostly westward (with speed $\\sim$5km/s), but there are cases showing eastward or poleward drifting. (5) The ...

    Full Text Available This study aimed to evaluate the effect of the environment on physiological responses and the influence of age on hematological parameters of Anglo-Nubian goats in the semiarid northeast. Were used 22 kids with 30-70 days old, distributed in a completely randomized design, in morning and afternoon shifts, with 22 repetitions. There was no effect of shifts for the variables rectal temperature and respiratory frequency. It was found mean rectal temperatures of 39.21 and 39.37 °C for the morning and afternoon shifts, respectively. For RF, observed averages of 39.23 and 42.68 mov. / Min for morning and afternoon, respectively. For ST, there was an average of 31.27 ° C for the morning shift and an average of 33.31 ° C for the afternoon, having the analysis of variance revealed effect of shift for all the different body parts of the animals and registered the highest average in the afternoon. For the parameters erythrocyte count, packed cell volume, mean corpuscular volume and mean corpuscular hemoglobin concentration, was significant effect of age. Already for mean hemoglobin and leukocytes, there was no significant difference between the ages studied. The physiological responses of the animals were maintained within the normal pattern, indicating that the thermoregulatory apparatus from the goats was effective in maintaining the homeothermy. The ST was influenced by ambient temperatures, rising in the afternoon shift. The age affects the majority of the blood constituents of young goats. Hematological data obtained can serve as a reference for young goats created in tropical environmental conditions.

  3. Sleeping pattern of kindergartners and nursery school children: function of daytime nap.

    Science.gov (United States)

    Fukuda, Kazuhiko; Sakashita, Yukine

    2002-02-01

    With a questionnaire answered by parents this study investigated the sleeping pattern of children attending kindergartens or nursery schools and the function of an afternoon nap. Sleeping pattern was investigated by a questionnaire with 441 young children (229 boys and 212 girls) attending kindergartens or nursery schools at the ages of 3 to 6 years old. Nighttime sleep did not show any significant change, while daytime naps decreased drastically and almost disappeared by the age of 6. Nursery school children went to bed later at night, so nighttime sleep was shorter than that of kindergartners. They also reported having more 'difficulty to fall asleep', more frequent 'staying-up at late night', less 'not getting enough sleep', worse 'mood at rising', and more 'unwillingness to go to their schools'. To investigate whether afternoon naps, which are routine at Japanese nursery schools, can compensate for sleep insufficiency on the previous night and whether they have the effect of delaying the onset of the subsequent nighttime sleep, we compared sleep duration on the previous night and the sleep onset time between the days with and without an afternoon nap. The afternoon nap appeared to cause delayed sleep onset but was not a result of sleep deficiency. PMID:11883566

  9. The timing of learning before night-time sleep differentially affects declarative and procedural long-term memory consolidation in adolescents.

    Directory of Open Access Journals (Sweden)

    Johannes Holz

    Full Text Available Sleep after learning has been shown to foster the consolidation of new memories. However, fundamental questions on the best timing of learning before night-time sleep persist. We tested the hypothesis that learning directly prior to night-time sleep compared to 7.5 hrs prior to night-time sleep provides better conditions for the consolidation of declarative and procedural memories. Fifty healthy female adolescents (aged 16-17 years were trained on a declarative word-pair and a procedural finger-tapping task at 3 pm (afternoon group, n = 25 or at 9 pm (evening group, n = 25, followed by a sleep laboratory night. Retrieval was assessed 24 hours and 7 days after initial training. Subjects trained in the afternoon showed a significantly elevated retention rate of word-pairs compared to subjects trained in the evening after 24 hours, but not after 7 days. In contrast, off-line gains in finger-tapping performance were significantly higher in subjects trained in the evening compared to those trained in the afternoon after both retention intervals. The observed enhanced consolidation of procedural memories after training in the evening fits to current models of sleep-related memory consolidation. In contrast, the higher retention of declarative memories after encoding in the afternoon is surprising, appeared to be less robust and needs further investigation.

    2016-01-01

    A stock market is a non-stationary complex system. The stock interactions are important for understanding the state of the market. However, our knowledge on the stock interactions on the minute timescale is limited. Here we apply the random matrix theory and methods in complex networks to study the stock interactions and sector interactions. Further, we construct a new kind of cross-correlation matrix to investigate the correlation between the stock interactions at different minutes within one trading day. Based on 50 million minute-to-minute price data in the Shanghai stock market, we discover that the market states in the morning and afternoon are significantly different. The differences mainly exist in three aspects, i.e. the co-movement of stock prices, interactions of sectors and correlation between the stock interactions at different minutes. In the afternoon, the component stocks of sectors are more robust and the structure of sectors is firmer. Therefore, the market state in the afternoon is more stable. Furthermore, we reveal that the information of the sector interactions can indicate the financial crisis in the market, and the indicator based on the empirical data in the afternoon is more effective.

The physical analysis of the thermal environment of the install was acquired in the weather station of the UFPI’s campus, which registered the temperature and air relative humidity. The wet bulb globe temperature index (WBGTI was obtained by a thermometer inserted into a black globe. There was significant difference (P<0.05 for all the weather variables, highlighting the air temperature, which had higher value in the afternoon shift (30.41 °C. A significant effect (P<0.05 was observed for the physiological variables respiratory rate and sweating rate, in which higher values were measured during the afternoon shift, being respectively 51.59 mov./min. and 104.69 g/m/h, probably because this shift showed the highest values for air temperature. The animals evaluated in this study showed a certain level of thermal discomfort, mainly in the afternoon shift.

However, our knowledge on the stock interactions on the minute timescale is limited. Here we apply the random matrix theory and methods in complex networks to study the stock interactions and sector interactions. Further, we construct a new kind of cross-correlation matrix to investigate the correlation between the stock interactions at different minutes within one trading day. Based on 50 million minute-to-minute price data in the Shanghai stock market, we discover that the market states in the morning and afternoon are significantly different. The differences mainly exist in three aspects, i.e. the co-movement of stock prices, interactions of sectors and correlation between the stock interactions at different minutes. In the afternoon, the component stocks of sectors are more robust and the structure of sectors is firmer. Therefore, the market state in the afternoon is more stable. Furthermore, we reveal that the information of the sector interactions can indicate the financial crisis in the market, and the indicator based on the empirical data in the afternoon is more effective.

  14. Diurnal water relations of walnut trees - Implications for remote sensing

    Science.gov (United States)

    Weber, James A.; Ustin, Susan L.

    1991-01-01

    Leaflet water content (WC), relative water content (RWC), and water potential, Phi(lf) were measured as indicators of diurnal change in tree water status in an experimental walnut orchard receiving two irrigation treatments: 100 and 33 percent of potential evapotranspiration (PET). Diurnal change was greatest in Phi(lf) throughout the experimental period, with minima occurring each day in early to mid-afternoon and maxima between midnight and sunrise. Leaflet WC and RWC were lower in the afternoon than at night, but had greater variability so that the diurnal pattern was not as clear. Comparison between the pattern of Phi(lf) and dielectric constants (DCs) measured from probes inserted 2 cm into a tree hole showed that both declined nearly in parallel in the morning. Phi(lf) recovered more rapidly than DC in the afternoon. This temporal discrepancy could be caused by cavitation of xylem elements in the vicinity of the DC probe. Microwave backscatter for L- and X-bands also measured diurnal variation that had local minima in the afternoon, but the pattern among wavelength and polarization signatures was complex.

    Milk samples from high and low milk producer Holstein cows, were obtained during the morning and afternoon milking over a one week period. Overall, 1064 samples were tested within 14 times sampling in Urmia, Iran. Milk macro-mineral concentrations in the morning milking and in low producers were greater than in the afternoon and in high producers. The highest and lowest concentrations were observed in Na(+) and Mg(++), respectively. Mean milk values between low and high producers in the morning, afternoon and daily milking times were different (p macro-minerals in the morning, afternoon and overall milking showed significant and positive correlations among all macro-minerals except for Na(+) and K(+), in which there was a significant negative correlation (p macro-minerals in different producers varied between milking times. The sodium concentration was the highest while Mg(++) was the lowest among macro-minerals. The correlation between Ca(++)/ IP was the highest, while Na(+)/K(+) revealed a negative correlation. Therefore, by organizing the appropriate macro-minerals in the ration, it would be possible to achieve an optimal purpose from animal husbandry.

    We evaluated human physiological responses and the performance of manual tasks during exposure to severe cold (-25 degrees C) at night (0300-0500 hours) and in the afternoon (1500-1700 hours). Thirteen male students wearing standard cold protective clothing occupied a severely cold room (-25 degrees C) for 20 min, and were then transferred to a cool room (10 degrees C) for 20 min. This pattern of exposure was repeated three times, for a total time of exposure to extreme cold of 60 min. The experiments were started either at 1500 hours or 0300 hours and measurements of rectal temperature, skin temperature, blood pressure, performance in a counting task, hand tremor, and subjective responses were made in each condition. At the end of the experiment at night the mean decrease in rectal temperature [0.68 (SEM 0.04) degree C] was significantly greater than that at the end of the experiment in the afternoon [0.55 (SEM 0.08) degree C, P second cold exposure at night the mean increase in diastolic blood pressure [90 (SEM 2.0) mmHg] was significantly greater than that at the end of the second cold exposure in the afternoon [82 (SEM 2.8) mmHg, P second cold exposure at night, mean finger skin temperature [11.8 (SEM 0.8) degrees C] was significantly higher than that at the comparable time in the afternoon [9.0 (SEM 0.7) degrees C, P second cold exposure at night [25.6 (SEM 1.5) degrees C] was significantly higher than in the afternoon [20.1 (SEM 0.8) degrees C, P < 0.01]. The increased skin temperatures in the periphery resulted in increased heat loss.

    2014-05-01

    The study aimed to examine shiftworkers fatigue and the longitudinal relationships that impact on fatigue such as team climate, work life conflict, control of shifts and shift type in shift working nurses. We used a quantitative survey methodology and analysed data with a moderated hierarchical multiple regression. After matching across two time periods 18 months apart, the sample consisted of 166 nurses from one Australian hospital. Of these nurses, 61 worked two rotating day shifts (morning & afternoon/evening) and 105 were rotating shiftworkers who worked three shifts (morning afternoon/evening and nights). The findings suggest that control over shift scheduling can have significant effects on fatigue for both two-shift and three-shift workers. A significant negative relationship between positive team climate and fatigue was moderated by shift type. At both Time 1 and Time 2, work life conflict was the strongest predictor of concurrent fatigue, but over time it was not.

    Based on relatively high spatial and temporal resolution satelite data collected at 0700 CST and at each hour from 1000 CST to 1700 CST during the summer of 1986, cloud and convection variations over the area from Mississippi east to Georgia and from the Gulf of Mexico north to Tennessee are discussed. The data analyses show an average maximum cloud frequency over the land areas at 1400 local time and a maximum of deep convection one hour later. Both cloudiness and deep convection are found to be at a maximum during the nocturnal hours over the Gulf of Mexico. Cloud frequency shows a strong relationship to small terrain features. Small fresh water bodies have cloud minima relative to the surroundings in the afternoon hours. Higher, steep terrain shows cloud maxima and the adjacent lower terrain exhibits afternoon cloud minima due to a divergence of mountain breeze caused by the valley.

    We investigated how the diagnosis of postural orthostatic tachycardia syndrome (POTS) would be changed due to diurnal variability in orthostatic tachycardia. The orthostatic vital sign test was administered to each patient twice, in the afternoon of the day of admission and the next morning (n = 113). Forty-six patients were diagnosed with POTS, and the remaining 67 patients were assigned to non-POTS group. Heart rate increments after standing were larger in the morning than in the afternoon in every group (all P orthostatic vital sign test. Orthostatic intolerance symptoms were provoked in only 45.7% of the POTS patients, more frequently in the morning. In conclusion, diurnal variability in hemodynamic parameters and provoked symptoms significantly challenged the diagnosis of POTS.

    Global distribution of the Terrestrial Gamma-ray Flashes (TGFs) detected by AGILE and RHESSI for the period from March 2009 to July 2012 has been analysed. A fourth TGF production region has been distinguished over the Pacific. It is confirmed that TGF occurrence follows the Intertropical Convergence Zone(ITCZ) seasonal migration and prefers afternoons. TGF/lightning ratio appears to be lower over America than other regions suggesting that meteorological regional differences are important for the TGF production. Diurnal cycle of TGFs peaks in the afternoon suggesting that Convective Available Potential Energy (CAPE) and convection are important for TGF production. Moreover all AGILE passages over South America in the same period have been analysed to find meteorological preferences for TGF occurrence. In each passage the analysis of Cloud Top Altitude (CTA), CAPE, number of strokes, number of storms and coverage area of clouds with temperatures below $-70\\,^{\\circ}{\\rm C}$ (Cloud Top Coverage area, CTC) are c...

  20. On the mutual relationship of the equatorial electrojet, TEC and scintillation in the Peruvian sector

    Khadka, Sovit M.; Valladares, Cesar; Pradipta, Rezy; Pacheco, Edgardo; Condor, Percy

    2016-06-01

    This paper presents the interrelationship between the equatorial electrojet (EEJ) strength, Global Positioning System (GPS)-derived total electron content (TEC), and postsunset scintillation from ground observations with the aim of finding reliable precursors of the occurrence of ionospheric irregularities. Mutual relationship studies provide a possible route to predict the occurrence of TEC fluctuation and scintillation in the ionosphere during the late afternoon and night respectively based on daytime measurement of the equatorial ionosphere. Data from ground based observations in the low latitudes of the west American longitude sector were examined during the 2008 solar minimum. We find a strong relationship exists between the noontime equatorial electrojet and GPS-derived TEC distributions during the afternoon mediated by vertical E × B drift via the fountain effect, but there is little or no relationship with postsunset ionospheric scintillation.

  1. Grassland birds orient nests relative to nearby vegetation

    Science.gov (United States)

    Hoekman, S.T.; Ball, I.J.; Fondell, T.E.

    2002-01-01

    We studied orientation of nest sites relative to nearby vegetation for dabbling ducks (Cinnamon Teal, Anas cyanoptera; Blue-winged Teal, A. discors; Gadwall, A. strepera; Mallard, A. platyrhynchos; and Northern Shoveler, A. clypeata) and Short-eared Owls (Asio flammeus) in ungrazed grassland habitat during 1995-1997 in westcentral Montana. We estimated an index of vegetation height and density in intercardinal directions (NE, SE, SW, NW) immediately around nests. All species oriented nests with the least vegetation to the southeast and the most vegetation to either the southwest or northwest. Furthermore, maximum vegetation around nests shifted from the southwest to the northwest with increasing nest initiation date, apparently as a response of individuals tracking seasonal change in the afternoon solar path. Thus, nests were relatively exposed to solar insolation during cool morning hours but were shaded from intense insolation in the afternoon throughout the breeding season. We suggest that nest microhabitat was selected in part to moderate the thermal environment.

    2003-01-01

    We present for the first time spectral behaviour of aerosol optical depths (AODs) over Manora Peak, Nainital located at an altitude of ~2 km in the central Himalayas. The observations were carried out using a Multi-Wavelength Solar Radiometer during January to December 2002. The primary features of the study are (i) larger AOD during afternoon periods compared to forenoon, attributable to change in the ray path from comparatively cleaner environment in the forenoon to polluted environment in the afternoon (ii) extremely low AODs during local winter and a remarkable increase to high values in summer (iii) a distinct change in the spectral dependencies of AODs from a relatively steeper spectra during winter to a shallower one in summer representing both transparent (meteorological aerosols) and polluted summer (urban haze aerosols) skies.The mean aerosol extinction law at Nainital during 2002 is best represented by $0.10 \\lambda^{-0.61}$.

    Eighty-four consecutive sentinel node biopsies were performed using dye and radioactive tracer (tin colloid for 42 tumors and phytate for 42 tumors). They had subdermal injection on the morning of surgery or the afternoon before surgery. Maximum RI count of each sentinel node was recorded and classified {<=}5 counts per second (cps), 5-20, or 20<. In injection on the afternoon before surgery, 19 tumors had {<=}5 cps and 2 had 20 cps< in 24 of tin colloid, whereas 1 had {<=}5 cps and 18 had 20 cps< in 22 of phytate. In injection on the morning of surgery, 9 had {<=}5 and 20 had 20< in 18 of tin colloid, whereas 1 had {<=}5 and 18 had 20< in 20 of phytate. The injection of phytate tended to have higher RI count than tin colloid. Phytate is superior to tin colloid for sentinel node biopsy in breast cancer. (author)

  8. Characteristics of urban ozone level in Hong kong

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    The long term trend of ozone level in Hong Kong has been investigated. One of the characteristics of ozone level in Hong Kong is the existence of autumn maximum and summer minimum. Observations of the diurnal variation of ozone level have been made in different area categories. There are early morning peak and afternoon peak occurred in the diurnal variation, which are different from some metropolitans where only an afternoon peak is observed. A negative correlation coefficient was found between monthly ozone level with nitric oxide level. On the contrary, there is a positive correlation between ozone and nitrogen dioxide. The positive correlation coefficient between nitric oxide and nitrogen dioxide shows that the total amount of nitric oxide emitted from a series of moving and fixed sources greatly exceeded the stoichiometric amount of ozone formed from chemical reactions of precursors and long distance transportation.

    Total of 1100 convective events in the 17-year warm-season climatology at KSC/CCAFS. July and August typically are the peak of convective events, May being the minimum. Warning and non-warning level convective winds are more likely to occur in the late afternoon (1900-2000Z). Southwesterly flow regimes and wind directions produce the strongest winds. Storms moving from southwesterly direction tend to produce more warning level winds than those moving from the northerly and easterly directions.

    The finding that bright light can suppress melatonin production led to the study of two situations, indeed, models, of light deprivation: totally blind people and winterdepressives. The leading hypothesis for winter depression (seasonal affective disorder, or SAD) is the phase shift hypothesis (PSH). The PSH was recently established in a study in which SAD patients were given low-dose melatonin in the afternoon/evening to cause phase advances, or in the morning to cause phase delays, or place...

    Full Text Available Milk samples from high and low milk producer Holstein cows, were obtained during the morning and afternoon milking over a one week period. Overall, 1064 samples were tested within 14 times sampling in Urmia, Iran. Milk macro-mineral concentrations in the morning milking and in low producers were greater than in the afternoon and in high producers. The highest and lowest concentrations were observed in Na+ and Mg++, respectively. Mean milk values between low and high producers in the morning, afternoon and daily milking times were different (p < 0.05. The individual comparison of milk parameters between both groups in the different milking times were also different (p < 0.05. The results of correlation among macro-minerals in the morning, afternoon and overall milking showed significant and positive correlations among all macro-minerals except for Na+ and K+, in which there was a significant negative correlation (p < 0.05. The highest and lowest correlations were found between Ca++ and inorganic phosphorus (IP (r=0.37, p < 0.05 and Na+ and IP (r=0.10, p < 0.05, respectively. It is concluded that the concentration of macro-minerals in different producers varied between milking times. The sodium concentration was the highest while Mg++ was the lowest among macro-minerals. The correlation between Ca++/ IP was the highest, while Na+/K+ revealed a negative correlation. Therefore, by organizing the appropriate macro-minerals in the ration, it would be possible to achieve an optimal purpose from animal husbandry.

    Full Text Available Speciated atmospheric mercury observations collected over the period from 2008 to 2010 at the Environmental Protection Agency and National Atmospheric Deposition Program Atmospheric Mercury Network sites (AMNet were analyzed for its spatial, seasonal, and diurnal characteristics across the US. Median values of gaseous elemental mercury (GEM, gaseous oxidized mercury (GOM and particulate bound mercury (PBM at 11 different AMNet sites ranged from 148–226 ppqv (1.32–2.02 ng m−3, 0.05–1.4 ppqv (0.47–12.4 pg m−3 and 0.18–1.5 ppqv (1.61–13.7 pg m−3, respectively. Common characteristics of these sites were the similar median levels of GEM as well as its seasonality, with the highest mixing ratios occurring in winter and spring and the lowest in fall. However, discernible differences in monthly average GEM were as large as 30 ppqv, which may be caused by sporadic influence from local emission sources. The largest diurnal variation amplitude of GEM occurred in the summer. Seven rural sites displayed similar GEM summer diurnal patterns, in that the lowest levels appeared in the early morning, and then the GEM mixing ratio increased after sunrise and reached its maxima at noon or in the early afternoon. Unlike GEM, GOM exhibited higher mixing ratios in spring and summer. The largest diurnal variation amplitude of GOM occurred in spring for most AMNet sites. The GOM diurnal minima appeared before sunrise and maxima appeared in the afternoon. The increased GOM mixing ratio in the afternoon indicated a photochemically driven oxidation of GEM resulting in GOM formation. PBM exhibited diurnal fluctuations in summertime. The summertime PBM diurnal pattern displayed daily maxima in the early afternoon and lower mixing ratios at night, implying photochemical production of PBM in summer.

    Measurements of air temperature and humidity in the urban canopy layer during July 2009 in 26 sites in Athens, Greece, allowed for the mapping of the hourly spatiotemporal evolution of the urban heat island (UHI) effect. City districts neighboring to the mountains to the east were the hottest during the afternoon, while being among the coolest during the early morning hours. While during the early morning some coastal sites were the hottest, the warm air plume slowly moved to the densely urbanized center of the city until 14:00-15:00, moving then further west, to the Elefsis industrial area in the afternoon. Results from the UrbClim model agree fairly well with the observations. Satellite-derived land surface temperature (LST) data from AATSR, ASTER, AVHRR and MODIS, for pixels corresponding to ground stations measuring Tair, showed that LST can be up to 5K lower than the respective Tair during nighttime, while it can be up to 15K higher during the rest of the day. Generally, LST during late afternoon as acquired from AATSR is very near to Tair for all stations and all days, i.e., the AATSR LST afternoon retrieval can be used as a very good approximation of Tair. The hourly evolution of the spatial Tair distribution was almost the same during days with NE Etesian flow as in days with sea breeze circulation, indicating that the mean wind flow was not the main factor controlling the diurnal UHI evolution, although it influenced the temperatures attained. No unambiguous observation of the urban moisture excess (UME) phenomenon could be made.

    Full Text Available OBJECTIVE: To evaluate the influences of circadian variations on tilt-table testing (TTT results by comparing the positivity rate of the test performed during the morning with that of the test performed in the afternoon and to evaluate the reproducibility of the results in different periods of the day. METHODS: One hundred twenty-three patients with recurrent unexplained syncope or near-syncope referred for TTT were randomized into 2 groups. In group I, 68 patients, TTT was performed first in the afternoon and then in the morning. In group II, 55 patients, the test was performed first in the morning and then in the afternoon. RESULTS: The TTT protocol was the prolonged passive test, without drug sensitization. Twenty-nine (23.5% patients had a positive result in at least one of the periods. The positivity rate for each period was similar: 20 (16.2% patients in the afternoon and 19 (15.4% in the morning (p=1.000. Total reproducibility (positive/positive and negative/negative was observed in 49 (89% patients in group I and in 55 (81% in group II. Reproducibility of the results was obtained in 94 (90.4% patients with first negative tests but in 10 (34% patients with first positive tests. CONCLUSION: TTT could be performed during any period of the day, and even in the 2 periods to enhance positivity. Considering the low reproducibility rate of the positive tests, serial TTT to evaluate therapeutic efficacy should be performed during the same period of the day.

    Full Text Available Abstract Background Studies examining the correlates of school transport commonly fail to make the distinction between morning and afternoon school trips. The purpose of this study was to examine the prevalence and correlates of mode shift from passive in the morning to active in the afternoon among elementary and secondary school students in Ontario, Canada. Methods Data were derived from the 2009 cycle of the Ontario Student Drug Use and Health Survey (OSDUHS. 3,633 students in grades 7 through 12 completed self-administered questionnaires. Socio-demographic, behavioural, psychological, and environmental predictors of active school transport (AST were assessed using logistic regression. Results Overall, 47% and 38% of elementary school students reported AST to and from school, respectively. The corresponding figures were 23% and 32% for secondary school students. The prevalence of AST varied temporarily and spatially. There was a higher prevalence of walking/biking found for elementary school students than for secondary school students, and there was an approximate 10% increase in AST in the afternoon. Different correlates of active school transport were also found across elementary and secondary school students. For all ages, students living in urban areas, with a shorter travel time between home and school, and having some input to the decision making process, were more likely to walk to and from school. Conclusions Future research examining AST should continue to make the analytic distinction between the morning and afternoon trip, and control for the moderating effect of age and geography in predicting mode choice. In terms of practice, these variations highlight the need for school-specific travel plans rather than 'one size fits all' interventions in promoting active school transport.

    Morning and afternoon levels of cortisol for 73 volunteers (67 women and 6 men) were compared in relation to their Binge Eating Disorder scores, Body Mass Indexes, and self-reports of mood and hunger. Cortisol level was not significantly correlated with binge eating or mood or hunger for either time period. However, it was inversely related to body mass, with lower cortisol levels associated with greater body mass. PMID:12530732

    Little is known about the influence of Telazol on cortisol or of anesthetic agents on immunological measures, and reports of ketamine's effect on cortisol are inconsistent. We measured effects of Telazol, ketamine and blood sampling on cortisol in male rhesus macaques and male savannah baboons. We also obtained leukocyte counts in the macaques. In macaques, Telazol reduced cortisol in the morning but not in the afternoon; ketamine had no effect on cortisol in these animals. In baboons, cortis...

    The space-time features of rainfall diurnal variation of precipitation are systematically investigated by using the Tropical Rainfall Measuring Mission (TRMM) precipitation products retrieved from TRMM microwave imager (TMI), precipitation radar (PR) and TMI/PR combined algorithms. Results demonstrate that diurnal variability of precipitation is obvious over tropical regions. The dominant feature of rainfall diurnal cycle over, ocean is that there is consistent rainfall peak in early morning, while there is a consistent rainfall peak in mid-late afternoon over land. The seasonal variation on intensity of rainfall diurnal cycle is clearly evidenced. Horizontal distributions of rainfall diurnal variations indicate that there is a clearly early-morning peak with a secondary peak in the middle-late afternoon in ocean rainfall at latitudes dominated by large-scale convergence and deep convection. There is also an analogous early-morning peak in land rainfall along with a stronger afternoon peak forced by surface heating. Amplitude analysis shows that the patterns and its evolution of rainfall diurnal cycle are very close to rainfall distribution pattern and its evolution. These results indicate that rainfall diurnal variations are strongly associated with large-scale convective systems and climate weather systems. Phase studies clearly present the regional and seasonal features of rainfall diurnal activities. Further studies on convective and stratiform rainfall show different characteristics of diurnal cycles. Their spatial and temporal variations of convective and stratiform rainfall indicate that mechanisms for rainfall diurnal variations vary with time and space.

    A study was conducted in corn-peanut and sweet potato-peanut fields on the flying behavior of the white grub parasitoid Tiphia popitliavora Rohwer wasps. Observation on the first three times of flying,after the wasps being released, revealed that the first flying was an escape style and not showed preference to land on any special crops. 81.82 % wasps landed on corn leaves at the second flying but stayed for just about 3min. In the sweet potato-peanut field, 51.43 % wasps landed on sweet potato in contrast with 48.57 % landed on peanuts and in the afternoon 33.53 % on sweet potato compared with 76.4 % landed on peanut field. Majority preferred landing on peanut field on the third flying in both type fields of inter-cropping. Behavior of flying was different between morning and afternoon. The time length between two flies showed that wasps were more active in the morning than in the afternoon.

    Full Text Available The aim of this paper was to measure the main aspects that characterize the resting behavior of eighteen months old heifers using two different resting space allowances. During the experiments the following resting behaviour aspects were determined: number of resting periods, the length of one resting period and the total length of resting periods. Results showed that when a resting space of 4.5 m2 per heifer was used the total length of laying down periods was 262.8 minutes in the morning, 159.5 minutes in the afternoon and 450.5 minutes during the night. When the size of the resting space was increased to 5.0 m2 per heifer, the total length of resting periods decreased to 137.2 minutes during the morning, 142.7 minutes in the afternoon and 396.8 minutes in the night. There were significant differences (p<0.05 between the two resting spaces for the total length of resting periods during the morning, afternoon and for 24 hours.

    Full Text Available The aim of this paper was to measure the main aspects that characterize the rumination behavior in six months old calves fed using three different feed spaces allowance. During the experiments the following rumination behavior aspects were determined: number of rumination periods, the length of rumination periods and the total length of rumination periods. Results showed that calves spent ruminating, on average, only 96.4 minutes in the morning, 176 minutes in the afternoon and 262.6 minutes during the night when the length of feeding space was 0.6 m per calf. Calves spent ruminating 124.2 minutes during the morning, 173.6 minutes during the afternoon and 243.4 minutes during the night when the length of the feeding space was 0.32 m per calf. Calves spent ruminating 106.2 minutes during the morning, 134.2 minutes during the afternoon and 286.4 minutes during the night when the length of the feeding space was 0.28 m per calf. The total time spent ruminating by calves was 535 minutes when the length of feeding space was 0.6 m per calf, 541 minutes when the length of feeding space was 0.32 per calf and 527 minutes when the length of the feeding space was 0.28 per calf. There were no significant differences (p>0.05 for total time spent ruminating by calves between the three experimental variants.

    The photosystem II (PSII) activity of C3 plants is usually inhibited at noon associated with high light but can be repaired fast in the afternoon. However, the diurnal variation of photosystem I (PSI) activity is unknown. Although, cyclic electron flow (CEF) has been documented as an important mechanism for photosynthesis, the diurnal variation of CEF in sun leaves is little known. We determined the diurnal changes in PSI and PSII activities, light energy dissipation in PSII and the P700 redox state in two tropical tree species Erythrophleum guineense and Khaya ivorensis grown in an open field. The PSI activity (as indicated by the maximum quantity of photo-oxidizable P700) was maintained stable during the daytime. CEF was strongly activated under high light at noon, accompanying with high levels of non-photochemical quenching (NPQ) and PSI oxidation ratio. In the afternoon, CEF was maintained at a relatively high level under low light, which was accompanied with low levels of NPQ and P700 oxidation ratio. These results indicated that CEF was flexibly modulated during daytime under fluctuating light conditions. Under high light at noon, CEF-dependent generation of proton gradient across the thylakoid membranes (ΔpH) mainly contributed to photoprotection for PSI and PSII. By comparison, at low light in the afternoon, the CEF-dependent formation of ΔpH may be important for PSII repair via an additional ATP synthesis. PMID:27486473

  12. Changes in evapotranspiration of summer and winter crops of netted melon [Cucumis melo] grown under glass in relation to meteorological and plant-related factors

    International Nuclear Information System (INIS)

    Measurements of evapotranspiration taken in the summer and winter on netted melon crops grown under glass were taken to characterize seasonal and daily changes. The data were compared to meteorological and plant-related factors to seek some relationships. Evapotranspiration followed a sigmoid curve until one week after pollination, and then decreased gradually during fruit growth. Cumulative evapotranspirations after transplanting were about 116 kg and 60 kg, respectively, for the summer and winter crops, whereas the peak evapotranspirations were 3.O kg plant(-1) day(-1) and 1.3 kg plant(-1) day(-1). The rapid increase h the evapotranspiration during the early stage was associated with the increase in leaf area; its gradual decrease during fruit growth was associated with a decrease in the transpiration potential of leaves. Therefore, irrigation amounts should be increased with leaf development and decreased with fruit growth. The curve of solar radiation in sunny summer days peaked at noon, whereas vapor pressure deficit usually peaked in early or mid afternoon; evapotranspirations in the afternoon had higher values than had those in the morning. In winter, vapor pressure deficit was relatively high during late afternoon and early morning because of heating, whereas it was low during the remainder of the day on account of low ventilation. These fluctuations led to a weak correlation between evapotranspiration and vapor pressure deficit. Regression analyses indicated that solar radiation was a main meteorological factor affecting evapotranspiration

In addition to the role of sleep, older adults report that they are “morning types” and that their cognitive and emotional abilities seem to be at a higher level in the morning hours. In this vein, this study is aimed at examining the effect of sleep combined with the “time of day” condition on a specific ability that is crucial for interpersonal communication, namely, emotion recognition, in older adults. Specifically, the study compared older adults’ performance in decoding emotions from ecologically valid, dynamic visual cues, in two conditions: “early in the morning and after night sleep”, and “in the afternoon and after many hours since night sleep”. An emotion recognition task was administered twice to 37 community-dwelling older adults. The results showed a statistically significant higher performance in the morning in decoding all emotions presented, compared to the afternoon condition. Pleasant surprise, sadness, and anxiety were revealed as the most difficult emotions to be recognized in the afternoon condition. Keywords: aging, cognition, emotion recognition

    Previous studies have demonstrated that afternoon naps can have a negative effect on subsequent nighttime sleep in children. These studies have mainly been based on sleep questionnaires completed by parents. To investigate the effect of napping on such aspects of sleep quality, we performed a study in which child activity and sleep levels were recorded using actigraphy. The parents were asked to attach actigraphy units to their child’s waist by an adjustable elastic belt and complete a sleep diary for 7 consecutive days. 50 healthy young toddlers of approximately 1.5 years of age were recruited. There was a significant negative correlation between nap duration and both nighttime sleep duration and sleep onset time, suggesting that long nap sleep induces short nighttime sleep duration and late sleep onset time. We also found a significant negative correlation between nap timing and nighttime sleep duration and also a significant positive correlation between nap timing and sleep onset time, suggesting that naps in the late afternoon also lead to short nighttime sleep duration and late sleep onset. Our findings suggest that duration-controlled naps starting early in the afternoon can induce a longer nighttime sleep in full-term infants of approximately 1.5 years of age. PMID:27277329

    Full Text Available Land surface temperatures (LSTs within tropical forests contribute to climate variations. However, observational data are very limited in such regions. This study used passive microwave remote sensing data from the Special Sensor Microwave/Imager (SSM/I and the Special Sensor Microwave Imager Sounder (SSMIS, providing observations under all weather conditions, to investigate the LST over the Amazon and Congo rainforests. The SSM/I and SSMIS data were collected from 1996 to 2012. The morning and afternoon observations from passive microwave remote sensing facilitate the investigation of the interannual changes of LST anomalies on a diurnal basis. As a result of the variability of cloud cover and the corresponding reduction of solar radiation, the afternoon LST anomalies tend to vary more than the morning LST anomalies. The dominant spatial and temporal patterns for interseasonal variations of the LST anomalies over the tropical rainforest were analyzed. The impacts of droughts and El Niños on this LST were also investigated. Differences between early morning and late afternoon LST anomalies were identified by the remote sensing product, with the morning LST anomalies controlled by humidity (according to comparisons with the National Centers for Environmental Prediction (NCEP reanalysis data.

    2015-11-01

    Multilevel modeling was used to examine the effects of morning pain intensity and morning positive and negative affect on pain's interference with afternoon work goal pursuit and with evening work goal progress in a community sample of 132 adults who completed a 21-day diary. The moderating effects of pain acceptance and pain catastrophizing on the associations between morning pain intensity and afternoon work goal interference were also tested. Results revealed that the positive relationship between morning pain intensity and pain's interference with work goal pursuit was significantly moderated by pain acceptance, but not by pain catastrophizing. Both morning pain intensity and positive affect exerted significant indirect effects on evening work goal progress through the perception of pain's interference with work goal pursuit in the afternoon. Furthermore, the mediated effect of morning pain on evening work goal progress was significant when pain acceptance was at the grand mean and 1 SD below the grand mean, but not when pain acceptance was 1 SD above the grand mean. Thus, it appears that high pain acceptance significantly attenuates pain's capacity to disrupt work goal pursuit. Moreover, morning positive affect appears to operate as a protective factor. Additional interpretations and potential explanations for some inconsistent outcomes are discussed along with limitations, clinical implications, and suggestions for future studies.

    Full Text Available There is a well-established link between hydration and improved cognitive performance among adults, with evidence of similar findings among children. No trials have investigated the impact of water provision on cognitive performance among schoolchildren in hot and arid low-resource settings. We conducted a randomized-controlled trial in five schools with limited water access in Chipata district in Eastern province, Zambia, to assess the efficacy of water provision on cognition. Pupils in grades 3-6 were randomly assigned to either receive a bottle of drinking water that they could refill throughout the day (water group, n = 149 or only have access to drinking water that was normally available at the school (control group, n = 143. Hydration was assessed in the morning before provision of water and in the afternoon through urine specific gravity (Usg measured with a portable refractometer. In the afternoon we administered six cognitive tests to assess short-term memory, concentration, visual attention, and visual motor skills. Morning prevalence of dehydration, defined as Usg≥1.020, was 42%. Afternoon dehydration increased to 67% among the control arm and dropped to 10% among the intervention arm. We did not find that provision of water or hydration impacted cognitive test scores, although there were suggestive relationships between both water provision and hydration and increased scores on tests measuring visual attention. We identified key improvements to the study design that are warranted to further investigate this relationship.ClinicalTrials.gov NCT01924546.

    This study is an attempt to define thermal comfort requirements for Friday prayer during the hot season of Riyadh, Saudi Arabia. According to Islam, a Muslim should perform his prayers five times a day. The obligatory five prayers are Subuh prayer immediately before dawn, Thohor prayer in the afternoon, Assor prayer in late afternoon, Maghreb prayer immediately after sunset, and Ishaa prayer early evening. Generally, Muslims are encouraged to perform all five prayers in a mosque. Friday prayer that replaces Thohor prayer once a week, should take place in one of the main mosques of the neighbourhood. The mosque where Friday prayer could be performed is known as Friday mosque. Usually Friday prayer is attended by hundreds of worshippers and takes place in the afternoon. Since the summer of Riyadh is characterised by a very high temperature and a very low relative humidity, the indoor climate of the Friday mosque (Al-Masjed Al-Gamae) need a special study. This is the second part of a series of field investigations dealing with thermal comfort requirements in the hot-dry region of Saudi Arabia. (author)

    Exposure of the skin to ultraviolet (UV) irradiation causes many detrimental effects through mechanisms related to oxidative stress and DNA damage. Excessive oxidative stress can cause apoptosis and cellular dysfunction of epidermal cells leading to cellular senescence and connective tissue degradation. Direct and indirect damage to DNA predisposes the skin to cancer formation. Chronic UV exposure also leads to skin aging manifested as wrinkling, loss of skin tone, and decreased resilience. Fortunately, human skin has several natural mechanisms for combating UV-induced damage. The mechanisms operate on a diurnal rhythm, a cycle that repeats approximately every 24 hours. It is known that the circadian rhythm is involved in many skin physiologic processes, including water regulation and epidermal stem cell function. This study evaluated whether UV damage and the skin's natural mechanisms of inflammation and repair are also affected by circadian rhythm. We looked at UV-induced erythema on seven human subjects irradiated with simulated solar radiation in the morning (at 08:00 h) versus in the afternoon (at 16:00 h). Our data suggest that the same dose of UV radiation induces significantly more inflammation in the morning than in the afternoon. Changes in protein expression relevant to DNA damage, such as xeroderma pigmentosum, complementation group A (XPA), and cyclobutane pyrimidine dimers (CPD) from skin biopsies correlated with our clinical results. Both XPA and CPD levels were higher after the morning UV exposure compared with the afternoon exposure. J Drugs Dermatol. 2016;15(9):1124-1130. PMID:27602977

    Long-range sex pheromones have been demonstrated for several cerambycid beetle species. Our field study on the mating behavior of Zorion guttigerum, on the basis of its temporal and spatial distributions on mating and feeding sites (flowers), and longevity, however, suggests that such pheromones are not used by this species. Plant characteristics rather than long-range sex pheromones may play an important role in bringing both sexes together. Adult activities on flowers occur exclusively during the day with two peaks, one around midday and the other in the late afternoon. Overall operational sex ratio is male-biased (≈1 ♀:1.5 ♂) but it becomes very highly male-biased (≈1 ♀:9 ♂) when mating and feeding activities decrease to the minimum in mid-afternoon, suggesting that females leave flowers to oviposit during that period of time. For cerambycid species whose females oviposit alone, and in which mating and oviposition occur on different plants or different plant parts, the operational sex ratio appears to vary significantly over time on the mating sites. The number and duration of pair-bondings also vary over time for Z. guttigerum. Fewer and shorter pair-bondings in the morning may suggest a strong sexual selection process. After ≈2 h of selection, both sexes tend to engage in longer pair-bondings and mate more times before females leave the mating sites in mid-afternoon. Details of the mating behavior are described here.

    1987-01-01

    Static and dynamic spirometric tests were performed in 21 healthy subjects (21-61 years old, 8 smokers and 9 ex-smokers) on 3 different days within 2 weeks. The design of the study allowed separation of the influence of learning and diurnal changes between 09.00 and 17.00 h. In addition, the reproducibility of the tests and the effect of inhalation of 2.5 mg of terbutaline sulphate were studied. No learning effect was observed. There were slight, but statistically significant differences between morning, noon and afternoon measurements. Thus, the residual volume and flow in the early phase of forced expiration were highest in the afternoon, while maximal voluntary ventilation was lower at noon than in the afternoon or morning. The intraindividual variabilities (defined as standard deviation of difference between first and second measurement) of total lung capacity, vital capacity and forced expiratory volume in 1 s (FEV1) were about 3% of the predicted values. The ratio of intra- to interindividual variability was 0.2-0.3. The remaining tests showed higher variability and a higher intra- to interindividual variability ratio. Terbutaline inhalation caused a significant increase in most forced expiratory flow variables. A 10% increase in FEV1 corresponded to a 50-60% increase in endexpiratory flow. In spite of this, the endexpiratory flow and mean transit time were better discriminators of the effects of bronchodilation in normal subjects. PMID:3602594

    The present study investigated the impact of a single oral ingestion of ginger on thermoregulatory function and fat oxidation in humans. Morning and afternoon oral intake of 1.0 g dried ginger root powder did not alter rectal temperature, skin blood flow, O2 consumption, CO2 production, and thermal sensation and comfort, or induce sweating at an ambient temperature of 28 °C. Ginger ingestion had no effect on threshold temperatures for skin blood flow or thermal sweating. Serum levels of free fatty acids were significantly elevated at 120 min after ginger ingestion in both the morning and afternoon. Morning ginger intake significantly reduced respiratory exchange ratios and elevated fat oxidation by 13.5 % at 120 min after ingestion. This was not the case in the afternoon. These results suggest that the effect of a single oral ginger administration on the peripheral and central thermoregulatory function is miniscule, but does facilitate fat utilization although the timing of the administration may be relevant.

    In this study, we present a case study on 16 October 2011 to show the first observational evidence of the influence of short period gravity waves in aerosol transport during daytime over the central Himalayan region. The Doppler lidar data has been utilized to address the daytime boundary layer evolution and related aerosol dynamics over the site. Mixing layer height is estimated by wavelet covariance transform method and found to be ~ 0.7 km, AGL. Aerosol optical depth observations during daytime revealed an asymmetry showing clear enhancement during afternoon hours as compared to forenoon. Interestingly, Fourier and wavelet analysis of vertical velocity and attenuated backscatter showed similar 50-90 min short period gravity wave signatures during afternoon hours. Moreover, our observations showed that gravity waves are dominant within the boundary layer implying that the daytime boundary layer dynamics is playing a vital role in transporting the aerosols from surface to the top of the boundary layer. Similar modulations are also evident in surface parameters like temperature, relative humidity and wind speed indicating these waves are associated with the dynamical aspects over Himalayan region. Finally, time evolution of range-23 height indicator snapshots during daytime showed strong upward velocities especially during afternoon hours implying that convective processes through short period gravity waves plays a significant role in transporting aerosols from the nearby valley region to boundary layer top over the site. These observations also establish the importance of wave induced daytime convective boundary layer dynamics in the lower Himalayan region.

    It is well known that night sleep is a decisive factor for the effective functioning of the human body and mind. In addition to the role of sleep, older adults report that they are "morning types" and that their cognitive and emotional abilities seem to be at a higher level in the morning hours. In this vein, this study is aimed at examining the effect of sleep combined with the "time of day" condition on a specific ability that is crucial for interpersonal communication, namely, emotion recognition, in older adults. Specifically, the study compared older adults' performance in decoding emotions from ecologically valid, dynamic visual cues, in two conditions: "early in the morning and after night sleep", and "in the afternoon and after many hours since night sleep". An emotion recognition task was administered twice to 37 community-dwelling older adults. The results showed a statistically significant higher performance in the morning in decoding all emotions presented, compared to the afternoon condition. Pleasant surprise, sadness, and anxiety were revealed as the most difficult emotions to be recognized in the afternoon condition. PMID:27621639

    We present the new version (v14) of the BIRA-IASB algorithm for the retrieval of formaldehyde (H2CO) columns from spaceborne UV-visible sensors. Applied to OMI measurements from Aura and to GOME-2 measurements from MetOp-A and MetOp-B, this algorithm is used to produce global distributions of H2CO representative of mid-morning and early afternoon conditions. Its main features include (1) a new iterative DOAS scheme involving three fitting intervals to better account for the O2-O2 absorption, (2) the use of earthshine radiances averaged in the equatorial Pacific as reference spectra, and (3) a destriping correction and background normalisation resolved in the across-swath position. For the air mass factor calculation, a priori vertical profiles calculated by the IMAGES chemistry transport model at 09:30 and 13:30 LT are used. Although the resulting GOME-2 and OMI H2CO vertical columns are found to be highly correlated, some systematic differences are observed. Afternoon columns are generally larger than morning ones, especially in mid-latitude regions. In contrast, over tropical rainforests, morning H2CO columns significantly exceed those observed in the afternoon. These differences are discussed in terms of the H2CO column variation between mid-morning and early afternoon, using ground-based MAX-DOAS measurements available from seven stations in Europe, China and Africa. Validation results confirm the capacity of the combined satellite measurements to resolve diurnal variations in H2CO columns. Furthermore, vertical profiles derived from MAX-DOAS measurements in the Beijing area and in Bujumbura are used for a more detailed validation exercise. In both regions, we find an agreement better than 15 % when MAX-DOAS profiles are used as a priori for the satellite retrievals. Finally, regional trends in H2CO columns are estimated for the 2004-2014 period using SCIAMACHY and GOME-2 data for morning conditions, and OMI for early afternoon conditions. Consistent features

    As part of the training programme for Swedish elite soldiers, a 10 day march is carried out with a heavy pack under active-service conditions. Six soldiers volunteered to take part in an investigation on the energy consumption with special regard to the lipid metabolism at different levels of physical effort. The degree of physical work was evaluated by continuous heart-rate recording and analysis of the excretion of epinephrine and norepinephrine in the urine. Fasting values of triglycerides and free fatty acids in blood plasma were determined and muscle biopsies (taken in the morning and in the afternoon) were analysed for lipoprotein-lipase (LPL) activity. After an overnight fast the free fatty acids were increased only in the mornings following days of heavy physical work. The plasma triglyceride concentrations were lowest in a morning proceeded by 3 days of heavy work. The muscle LPL activity in the morning was highest after a day of heavy work and lowest after days of rest. During days of heavy work this activity increased and was higher in the afternoon than in the morning. Muscle LPL activity in the afternoon was closely related to urinary excretion of epinephrine. The data indicate that LPL activity is elevated in the working skeletal muscle increasing the access of fatty acids. The degree of elevation is related to the degree of effort as described by the urinary excretion of morning. Muscle LPL activity in the afternoon was closely related to urinary excretion of epinephrine. The data indicate that LPL activity is elevated in the working skeletal muscle increasing the access of fatty acids.

    Full Text Available Effects of providing grit on daily behavioural activities of intensively kept ostriches were investigated at the Botswana College of Agriculture. Two groups of ostriches were each housed in a 30 x 6m pen. Each group had seven ostriches in it. Each member of the group was identified by a number tag attached to its neck. Activities studied were feeding, picking objects, walking about, sparring, standing rest, sitting rest, grooming self, and grooming others. The study lasted 30 days. The results of the study show that during the mornings and afternoons, ostriches without access to grit allocated significantly (P<0.05 greater proportion of their activity time to feeding than did those with access to grit. The proportion of time allocated to morning feeding by the non-grit group was 23.1% as opposed to 13.9% for the grit group. In the afternoon, the non-grit group of ostriches continued allocating significantly more time (13.3 % to feeding than the grit group which only allocated 4.8% of their activity to the same activity. This trend in apportioning activity time by the two groups of ostriches was maintained with regards to the proportion of time allocated to walking about in the pens. The non-grit group allocated significantly (P<0.05 greater proportions of time to walking than the grit group. In the morning, non-grit ostriches allocated 25.8% of their daily activity to walking about in the pen while their grit counterparts allocated 19.9% to the same activity. The grit-fed group of ostriches rested more as they allocated significantly higher proportion (28.1% of their afternoon time to resting while standing than the proportion (17.7% allocated to the same by the non-grit group. Both treatment groups allocated higher proportions of their activity times to morning feeding. The group with access to grit spent 35.2% of the morning time feeding while allocating only 22.5% for the same activity in the afternoon feeding. The non-grit group allocated 24

    Changes in diurnal patterns in water transport and physiological activities in response to changes in environmental conditions are important adjustments of trees to drought. The rate of sap flow (SF) in trees is expected to be in agreement with the rate of tree-scale transpiration (T) and provides a powerful measure of water transport in the soil-plant-atmosphere system. The aim of this five-years study was to investigate the temporal links between SF and T in Pinus halepensis exposed to extreme seasonal drought in the Yatir forest in Israel. We continuously measured SF (20 trees), the daily variations in stem diameter (ΔDBH, determined with high precision dendrometers; 8 trees), and ecosystem evapotranspiration (ET; eddy covariance), which were complemented with short-term campaigns of leaf-scale measurements of H2O and CO2 gas exchange, water potentials, and hydraulic conductivity. During the rainy season, tree SF was well synchronized with ecosystem ET, reaching maximum rates during midday in all trees. However, during the dry season, the daily SF trends greatly varied among trees, allowing a classification of trees into three classes: 1) Trees that remain with SF maximum at midday, 2) trees that advanced their SF peak to early morning, and 3) trees that delayed their SF peak to late afternoon hours. This classification remained valid for the entire study period (2010-2015), and strongly correlated with tree height and DBH, and to a lower degree with crown size and competition index. In the dry season, class 3 trees (large) tended to delay the timing of SF maximum to the afternoon, and to advance their maximum diurnal DBH to early morning, while class 2 trees (smaller) advanced their SF maximum to early morning and had maximum daily DBH during midday and afternoon. Leaf-scale transpiration (T), measurements showed a typical morning peak in all trees, irrespective of classification, and a secondary peak in the afternoon in large trees only. Water potential and

    International Nuclear Information System (INIS)

    Twelve ostrich aged 7 months old were used during summer and winter from the breeding flock of the ostrich farm, at the Nuclear Research Center in Inshas, of Atomic Energy Authority, Egypt. In the study all birds were exposed to ambient temperatures in summer and winter, and the birds were fed grower ration ad libitum (19% protein and 2450 K cal ME /Kg).The present study was carried out to evaluate the effect of temperature variation during summer and winter seasons and diurnal effect on changes in some physiological and blood chemical parameters, the daily feed consumption (g/bird/day) and water consumption (ml/bird/day) these parameters were measured during 7 days in each season. Cloacal temperatures was measured and blood samples were taken twice, one in the morning at 7 am and once in the afternoon at 3 pm during a representative 7 hot days of June (40±2 degree C) (summer) and the 7 cold days of January (18±2 degree C) (winter). Red blood cell (RBCs) counts and total white blood cell (WBCs) counts, hemoglobin concentration (Hb) and packed cell volume (PCV) were determined. Mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular hemoglobin concentrations (MCHC) were calculated. Serum, total protein (TP), albumen (A) and globulin (G) concentrations were measured. Furthermore, serum alanine transaminase (ALT), aspartate transaminase (AST), glucose and triglycerides concentrations were determined. Also, serum triiodothyronine (T3), and aldosterone levels were estimated. Also, the amount of total body water was determined by the antipyren method. Finally, serum protein profile it was conducted by Native-PAGE method (Native polyacrylamide gel electrophoresis) on vertical slab gel to determine protein profiles in blood proteins of ostrich. Results indicated that feed consumption unlike water consumption was significantly increased during winter than in summer season. Moreover, body temperature increased significantly during the summer

    Full Text Available Abstract Background Sleep disturbance is a major health issue in Japan. This before-after study aimed to evaluate the immediate effects of forest walking in a community-based population with sleep complaints. Methods Participants were 71 healthy volunteers (43 men and 28 women. Two-hour forest-walking sessions were conducted on 8 different weekend days from September through December 2005. Sleep conditions were compared between the nights before and after walking in a forest by self-administered questionnaire and actigraphy data. Results Two hours of forest walking improved sleep characteristics; impacting actual sleep time, immobile minutes, self-rated depth of sleep, and sleep quality. Mean actual sleep time estimated by actigraphy on the night after forest walking was 419.8 ± 128.7 (S.D. minutes whereas that the night before was 365.9 ± 89.4 minutes (n = 42. Forest walking in the afternoon improved actual sleep time and immobile minutes compared with forest walking in the forenoon. Mean actual sleep times did not increase after forenoon walks (n = 26 (the night before and after forenoon walks, 380.0 ± 99.6 and 385.6 ± 101.7 minutes, respectively, whereas afternoon walks (n = 16 increased mean actual sleep times from 342.9 ± 66.2 to 475.4 ± 150.5 minutes. The trend of mean immobile minutes was similar to the abovementioned trend of mean actual sleep times. Conclusions Forest walking improved nocturnal sleep conditions for individuals with sleep complaints, possibly as a result of exercise and emotional improvement. Furthermore, extension of sleep duration was greater after an afternoon walk compared to a forenoon walk. Further study of a forest-walking program in a randomized controlled trial is warranted to clarify its effect on people with insomnia.

    In this paper, the diurnal variations of aerosol optical properties and their influences on the estimation of daily average direct aerosol radiative effect (DARE) in the North China Plain (NCP) are investigated based on in situ measurements from Haze in China campaign. For ambient aerosol, the diurnal patterns of single scattering albedo (SSA) and asymmetry factor (g) in the NCP are both highest at dawn and lowest in the late afternoon, and quite different from those of dry-state aerosol. The relative humidity is the dominant factor which determines the diurnal patterns of SSA and g for ambient aerosol. Basing on the calculated SSA and g, several cases are designed to investigate the impacts of the diurnal changes of aerosol optical properties on DARE. The results demonstrate that the diurnal changes of SSA and g in the NCP have significant influences on the estimation of DARE at the top of the atmosphere (TOA). If the full temporal coverage of aerosol optical depth (AOD), SSA and g are available, an accurate estimation of daily average DARE can be achieved by using the daily averages of AOD, SSA and g. However, due to the lack of full temporal coverage datasets of SSA and g, their daily averages are usually not available. Basing on the results of designed cases, if the RH plays a dominant role in the diurnal variations of SSA and g, we suggest that using both SSA and g averaged over early morning and late afternoon as inputs for radiative transfer model to improve the accurate estimation of DARE. If the temporal samplings of SSA or g are too few to adopt this method, either averaged over early morning or late afternoon of both SSA and g can be used to improve the estimation of DARF at TOA.

    Analyzed data consist of 8900 hourly average mobility distributions measured in the mobility range of 0.00041-3.2 cm2 V-1 s-1 (diameter range 0.36-79 nm) at Tahkuse Observatory, Estonia, in 1993-1994. The average diurnal variation in the concentration of cluster ions is typical for continental stations: the maximum in the early morning hours and the minimum in the afternoon. This is explained by variations in radon concentration. The diurnal variation for big cluster ions (0.5-1.3 cm2 V-1 s-1) differs from that for small cluster ions (1.3-3.14 cm2 V-1 s-1). The size distribution of intermediate and light large ions in the range of 1.6-22 nm is strongly affected by nucleation bursts of nanometer particles. On the burst days, the maximum concentration of intermediate ions (1.6-7.4 nm) is about the noontime and that of light large ions (7.4-22 nm) about 2 hours later. The concentration of heavy large ions (charged Aitken particles of diameters of 22-79 nm) is enhanced in the afternoon and this is explained by the bursts of nanometer particles and the subsequent growth of particles by condensation and coagulation. If the burst days are excluded, then in the warm season the concentration of Aitken particles increases during night. In the cold season, the diurnal variation is different and all the classes of aerosol ions (2.1-79 nm) show similar variation with the minimum at 0600 LT and the maximum in the afternoon; exceptions are the rare nucleation burst days.

  18. Physiological and Molecular Response of Ostrich to the Seasonal and Diurnal Variations in Egyptian conditions

    International Nuclear Information System (INIS)

    Twelve immature ostrich›s birds, 7 months old were used to evaluate the effect of ambient temperature variation and diurnal effect on response changes of some physiological and chemical parameters. All birds were reared out doors and exposed to daily ambient temperatures fluctuations during summer and winter. Blood samples were taken twice, one in the morning at 7 Am and once in the afternoon at 3 Pm during a representative 7 hot days of June (summer) (40±2ºC) and the 7 cold days of January (winter) (18±2ºC). Serum calcium, inorganic phosphorus, sodium, potassium, uric acid concentrations and aldosterone level were determined. The amount of total body water (TBW) and serum heat shock proteins (HSP) were estimated. Serum calcium, phosphorus, sodium and potassium concentrations in ostrich were significantly decreased, while uric acid concentration and aldosterone hormone level were significantly increased in summer as compared in winter during both at morning and at afternoon periods. Concerning the diurnal variation, serum calcium, phosphorus, sodium and potassium concentrations and aldosterone hormone level in ostrich were significantly increased, while uric acid concentration was significantly decreased at morning as compared at afternoon during both summer and winter seasons. TBW was significantly higher in summer season by 15.04% than winter season. It is concluded from the present study that heat or cold stress has a negative effect on most of the parameters studied and we recommend must be supplement diet with some nutrients like vitamins C, and E, sodium bicarbonate or yeast to overcome the negative effect and to better perform under such conditions

    Full Text Available Volatile organic compounds (VOCs and carbonaceous aerosol were measured at a sub-urban site near Mexico City in March of 2006 during the MILAGRO study (Megacity Initiative: Local and Global Research Objectives. Diurnal variations of hydrocarbons, elemental carbon (EC and hydrocarbon-like organic aerosol (HOA were dominated by a high peak in the early morning when local emissions accumulated in a shallow boundary layer, and a minimum in the afternoon when the emissions were diluted in a significantly expanded boundary layer and, in case of the reactive gases, removed by OH. In comparison, diurnal variations of species with secondary sources such as the aldehydes, ketones, oxygenated organic aerosol (OOA and water-soluble organic carbon (WSOC stayed relatively high in the afternoon indicating strong photochemical formation. Emission ratios of many hydrocarbon species relative to CO were higher in Mexico City than in the U.S., but we found similar emission ratios for most oxygenated VOCs and organic aerosol. Secondary formation of acetone may be more efficient in Mexico City than in the U.S., due to higher emissions of alkane precursors from the use of liquefied petroleum gas. Secondary formation of organic aerosol was similar between Mexico City and the U.S. Combining the data for all measured gas and aerosol species, we describe the budget of total observed organic carbon (TOOC, and find that the enhancement ratio of TOOC relative to CO is conserved between the early morning and mid afternoon despite large compositional changes. Finally, the influence of biomass burning is investigated using the measurements of acetonitrile, which was found to correlate with levoglucosan in the particle phase. Diurnal variations of acetonitrile indicate a contribution from local burning sources. Scatter plots of acetonitrile versus CO suggest that the contribution of biomass burning to the enhancement of most gas and aerosol species was not dominant and perhaps

This cross-sectional study includes n = 1314 participants aged 20-79 who were interviewed during the Cardiac health "Semanas del Corazon" events in four Spanish cities (Madrid, Las Palmas, Seville and Valencia) in 2008. Waist circumference, weight and height were assessed to determine abdominal obesity (waist circumference: ≥88 cm in women and ≥102 cm in men) and BMI, respectively. The intake of forenoon and afternoon meal and snacking between the participants' regular meals were assessed with a questionnaire that also included individual risk factors. The information obtained about diet was required to calculate an Unhealthy Habit Score and a score reflecting the Achievement of Dietary Guidelines. Adjusted logistic regressions were used to examine the association between abdominal obesity and the mentioned meal intake behaviour controlling for sex, age, individual risk factors, BMI and diet. Having an afternoon meal (OR 0.60; 95% CI (0.41-0.88)) was negatively associated with abdominal obesity after adjusting for all confounders, whereas the positive association of snacking (OR 1.39; 95% CI (1.05-1.85)) was not independent of BMI (OR 1.25; 95% CI (0.84-1.87)). Taking a forenoon meal did not show any associations (OR 0.92; 95% CI (0.63-1.34)) with abdominal obesity. The results obtained could be helpful in the promotion of healthy habits in nutritional education programmes and also in health programmes preventing abdominal obesity.

    Poplars are an important agro-forestry product used for both biofuel and paper production. Importantly, all poplars are not created equal - some have the potential to produce isoprene, a compound thought to aid plants under temperatures and water stress conditions. Isoprene production, then, would be an important feature in a plant's response to projected climatic changes of warmer temperatures and longer inter-storm periods of drought. Our project observed how drought conditions modulated photosynthetic rates in two lineages of Populus trees, those that produce isoprene and those that have had isoprene gene knocked out. We measured leaf-level photosynthesis and thermal sensitivity from the two lineages under high and low soil water conditions in a common garden experiment. We found that both lines had similar photosynthetic rates over the range of temperatures and water exposure levels measured. However, we wondered if some of the variation we found in our data was due to the time of day of the measurements. Subsequent measurements of photosynthetic rates in the morning and afternoon on the same leaves illustrated that poplars reached higher rates of photosynthesis in the morning, but ultimately decreased faster than observed in the afternoon measurements (indicative of an eased thermal sensitivity in the afternoon). Also, we used measures of soil moisture and leaf water potential to determine that the "drought" treatment we had induced didn't actually yield any differences in the moisture status among the trees. Ultimately, our experiment showed that isoprene did not aid in photosynthesis under heat stressed conditions and that the common garden setting was not able to currently induce a water stress condition in the plants. We have begun exploring the use of low-altitude remote sensing by an unmanned aerial vehicles outfitted with thermal and multi-spectral cameras to quantify patterns of transpirational water loss, NDVI, leaf browning due to moisture stress

    Full Text Available This study evaluates the influence of different irrigation frequencies and different nitrogen fertigation frequencies on the growth performance of the watermelon (Citrullus lanatus culture. Two experiments were conducted at the Paraguay farm in the Cruz municipality, Ceará, Brazil. They was randomized blocks design with six treatments and four replications. The irrigation frequency experiment consisted of the application of different irrigation frequencies. The treatments were: DM - daily irrigation in the morning with 100% daily dosage; DT - daily irrigation in the afternoon, with 100% daily dosage; DMT - twice daily irrigation, with 50% daily dosage in the morning and 50% daily dosage in the afternoon; 2D - irrigation every two days; 3D - irrigation every three days and 4D - irrigation every four days. To the experiment with different nitrogen fertigation frequencies, the treatments used were: 2F - 2 fertigations in a cycle; 4F - 4 fertigations in a cycle; 8F - 8 fertigations in a cycle; 16F - 16 fertigations in a cycle; 32F - 32 fertigations in a cycle and 64F - 64 fertigations in a cycle. We evaluated the marketable yield (PC, fruit weight (M, polar diameter (DP, equatorial diameter (DE, shell thickness (EC and soluble solids (SS. The irrigation frequency treatments influenced all variables significantly, with twice daily irrigation (DMT, 50% in the morning and the 50% in the afternoon promoting the highest productivity (69.79 t ha-1. The different frequencies of fertigation also significantly influenced all variables, except for the shell thickness, the highest yield (80.69 t ha-1 being obtained with treatment 64 fertigations in a cycle.

    Full Text Available Abstract Background The occurrence of variations in the spectrum of cardiovascular disease between different regions of the world and ethnic groups have been the subject of great interest. This study report the 24-h variation of myocardial infarction (MI occurrence in patients recruited from CCU located in Argentina and Uruguay. Methods A cohort of 1063 patients admitted to the CCU within 24 h of the onset of symptoms of an acute MI was examined. MI incidence along the day was computed in 1 h-intervals. Results A minimal MI incidence between 03:00 and 07:00 h and the occurrence of a first maximum between 08:00 and 12:00 h and a second maximum between 15:00 and 22:00 h were verified. The best fit curve was a 24 h cosinor (acrophase ~ 19:00 h, accounting for 63 % of variance together with a symmetrical gaussian bell (maximum at ~ 10:00 h, accounting for 37 % of variance. A similar picture was observed for MI frequencies among different excluding subgroups (older or younger than 70 years; with or without previous symptoms; diabetics or non diabetics; Q wave- or non-Q wave-type MI; anterior or inferior MI location. Proportion between cosinor and gaussian probabilities was maintained among most subgroups except for older patients who had more MI at the afternoon and patients with previous symptoms who were equally distributed among the morning and afternoon maxima. Conclusion The results support the existence of two maxima (at morning and afternoon hours in MI incidence in the Argentine and Uruguayan population.

    Full Text Available The precise relationship between sleep and physical and mental functioning in chronic fatigue syndrome (CFS has not been examined directly, nor has the impact of daytime napping. This study aimed to examine self-reported sleep in patients with CFS and explore whether sleep quality and daytime napping, specific patient characteristics (gender, illness length and levels of anxiety and depression, predicted daytime fatigue severity, levels of daytime sleepiness and cognitive functioning, all key dimensions of the illness experience.118 adults meeting the 1994 CDC case criteria for CFS completed a standardised sleep diary over 14 days. Momentary functional assessments of fatigue, sleepiness, cognition and mood were completed by patients as part of usual care. Levels of daytime functioning and disability were quantified using symptom assessment tools, measuring fatigue (Chalder Fatigue Scale, sleepiness (Epworth Sleepiness Scale, cognitive functioning (Trail Making Test, Cognitive Failures Questionnaire, and mood (Hospital Anxiety and Depression Scale.Hierarchical Regressions demonstrated that a shorter time since diagnosis, higher depression and longer wake time after sleep onset predicted 23.4% of the variance in fatigue severity (p <.001. Being male, higher depression and more afternoon naps predicted 25.6% of the variance in objective cognitive dysfunction (p <.001. Higher anxiety and depression and morning napping predicted 32.2% of the variance in subjective cognitive dysfunction (p <.001. When patients were classified into groups of mild and moderate sleepiness, those with longer daytime naps, those who mainly napped in the afternoon, and those with higher levels of anxiety, were more likely to be in the moderately sleepy group.Napping, particularly in the afternoon is associated with poorer cognitive functioning and more daytime sleepiness in CFS. These findings have clinical implications for symptom management strategies.

    Ozone (O3) concentrations measured at Pinnacle State Park (PSPNY), very close to the southern border of New York State, are used to estimate concentrations in air flowing into New York. On 20% of the ozone season (April-September) afternoons from 2004 to 2015, mid-afternoon 500-m back trajectories calculated from PSPNY cross New York border from the south and spend less than three hours in New York State, in this area of negligible local pollution emissions. One-hour (2p.m.-3p.m.) O3 concentrations during these inflowing conditions were 46 ± 13 ppb, and ranged from a minimum of 15 ppb to a maximum of 84 ppb. On average during 2004-2015, each year experienced 11.8 days with inflowing 1-hr O3 concentrations exceeding 50 ppb, 4.3 days with O3 > 60 ppb, and 1.5 days had O3 > 70 ppb. During the same period, 8-hr average concentrations (10a.m. to 6p.m.) exceeded 50 ppb on 10.0 days per season, while 3.9 days exceeded 60 ppb, and 70 ppb was exceeded 1.2 days per season. Two afternoons of minimal in-state emission influences with high ozone concentrations were analyzed in more detail. Synoptic and back trajectory analysis, including comparison with upwind ozone concentrations, indicated that the two periods were characterized as photo-chemically aged air containing high inflowing O3 concentrations most likely heavily influenced by pollution emissions from states upwind of New York including Pennsylvania, Tennessee, West Virginia, and Ohio. These results suggest that New York state-level attempts to comply with National Ambient Air Quality Standards by regulating in-state O3 precursor NOx and organic emissions would be very difficult, since air frequently enters New York State very close to or in excess of Federal Air Quality Standards.

  8. HF Doppler observations of vector plasma drifts in the evening F-region at the magnetic equator

    Balan, N.; Jayachandran, B.; Balachandran Nair, R.; Namboothiri, S. P.; Bailey, G. J.; Rao, P. B.

    Using HF Doppler radar in a spaced-receiver configuration, observations conducted on the vector plasma drifts in the equatorial F-region at Trivandrum during the afternoon-midnight period of March-April 1988, are presented. The three components of the F-region plasma drift at the magnetic equator are such that the North-South component corresponds to the meridional neutral air wind while the other two components represent the electrodynamic drift. The vertical component of the plasma drift is characterized by a prereversal upward enhancement which fits the interpretation based on the F-region dynamo operating at sunset. Equatorial spread-F, which is linked to the prereversal enhancement, appears to be inhibited during the main phase of magnetic storms. The East-West component of the plasma drift is westward during the afternoon and eastward during the night with mean peak velocities of 30 and 110 ms -1, respectively. The large night-time drift is believed to be due to a large reduction in the degree of electromagnetic coupling between the E- and F-regions during the night. The North-South component, representing the meridional neutral air wind, is found to be northward during the afternoon and southward during the night with respective mean peak velocities of about 50 and 70 m s -1. The neutral air wind shows a tendency to reverse from southward to northward at around midnight and is thought to be caused by the midnight bulge in the neutral air temperature. The observations which correspond to the lower F-region are found to be consistent with those reported earlier using other experimental techniques.

    Full Text Available The behavioural patterns and their cireadian rhythms may be adaptive to the peculiar environmental conditions of subtropical brackish waters where Ba-thygobius soporator Valenciennes, 1837 live. Adult fish were caught at the southern Brazilian coast from mangrove rivers and rocky shores in a bay, where temperature and water salinity vary during the day and through the year. Observation on the behaviour of the animals was undertaken in salinity 8.5ppt, 17.0ppt, 25.5ppt and 34.0ppt, each one in temperatures of 18ºC and 28ºC. Temperature and salinity affect the frequency and intensity of some of the behavioural events, more than its pattern or rhythm. Swimming is rare, decreasing along the day and with temperature increase, being even lower at low salinity; aggressiveness is the highest in the morning being not affected by temperature, but by salinity, being higher the higher it is; territory defence decreases along the day and is lower at high temperature and extreme salinities; fish hide more at high temperature and with the decrease of salinity, but this is not rhythmical; a higher proportion of fish rest in vertical position when salinity and temperature are high, increasing slightly at the beginning of the afternoon; respiratory frequency increases with temperature, salinity and in the afternoon; the colour of the fish is mainly light with spots in all hours of the day and in all temperatures and different levels of salinity, but with a tendency of the presence of some dark fish during the morning and some light ones in the afternoon, showing a higher variability of colours at low temperature and extreme salinities. Besides temperature, salinity and light, feeding seems to be one of the determinant factors for the performance of the typical behaviour of B. soporator.

    Full Text Available We present and evaluate the retrieval of high spatial resolution maps of NO2 vertical column densities (VCD from the Airborne Prism EXperiment (APEX imaging spectrometer. APEX is a novel instrument providing airborne measurements of unique spectral and spatial resolution and coverage as well as high signal stability. In this study, we use spectrometer data acquired over Zurich, Switzerland, in the morning and late afternoon during a flight campaign on a cloud-free summer day in June 2010. NO2 VCD are derived with a two-step approach usually applied to satellite NO2 retrievals, i.e. a DOAS analysis followed by air mass factor calculations based on radiative transfer computations. Our analysis demonstrates that APEX is clearly sensitive to NO2 VCD above typical European tropospheric background abundances (>1 × 1015 molec cm−2. The two-dimensional maps of NO2 VCD reveal a very plausible spatial distribution with strong gradients around major NOx sources (e.g. Zurich airport, waste incinerator, motorways and low NO2 in remote areas. The morning overflights resulted in generally higher NO2 VCD and a more distinct pattern than the afternoon overflights which can be attributed to the meteorological conditions prevailing during that day (development of the boundary layer and increased wind speed in the afternoon as well as to photochemical loss of NO2. The remotely sensed NO2 VCD are also highly correlated with ground-based in-situ measurements from local and national air quality networks (R=0.73. Airborne NO2 remote sensing using APEX will be valuable to detect NO2 emission sources, to provide input for NO2 emission modeling, and to establish links between in-situ measurements, air quality models, and satellite NO2 products.

  12. Optical performance of vertical axis three azimuth angles tracked solar panels

    International Nuclear Information System (INIS)

    In this work, a new sun-tracking concept was proposed, and the optical performance of solar panels with such sun-tracking system was theoretically investigated based on the developed mathematical method and monthly horizontal radiation. The mechanism of the proposed sun-tracking technique is that the azimuth angle of solar panels is daily adjusted three times at three fixed positions: eastward, southward and westward in the morning, noon, and afternoon, respectively, by rotating solar panels about the vertical axis (3A sun-tracking, in short). The analysis indicated that the tilt-angle of solar panels, β3A, azimuth angle of solar panels in the morning and afternoon from due south, φa, and solar hour angle when the azimuth angle adjustment was made in the morning and afternoon, ωa, were three key parameters affecting the optical performance of such tracked solar panels. Calculation results showed that, for 3A tracked solar panels with a yearly fixed tilt-angle, the maximum annual collectible radiation was above 92% of that on a solar panel with full 2-axis sun-tracking; whereas for those with the tilt-angle being seasonally adjusted, it was above 95%. Results also showed that yearly or seasonally optimal values of β3A, φa and ωa for maximizing annual solar gain were related to site latitudes, and empirical correlations for a quick estimation of optimal values of these parameters were proposed based on climatic data of 32 sites in China.

    There is extensive evidence that sleep restriction alters endocrine function in healthy young men, increasing afternoon cortisol levels and modifying levels of other hormones that regulate metabolism. Recent studies have confirmed these effects in young women, but have not investigated whether menstrual cycle phase influences these responses. The effects on cortisol levels of limiting sleep to 3h for one night were assessed in two groups of women at different points in their menstrual cycles: mid-follicular and mid-luteal. Eighteen healthy, young women, not taking oral contraceptives (age: 21.8±0.53; BMI: 22.5±0.58 [mean±SEM]), were studied. Baseline sleep durations, eating habits and menstrual cycles were monitored. Salivary samples were collected at six times of day (08:00, 08:30, 11:00, 14:00, 17:00, 20:00) during two consecutive days: first after a 10h overnight sleep opportunity (Baseline) and then after a night with a 3h sleep opportunity (Post-sleep restriction). All were awakened at the same time of day. Women in the follicular phase showed a significant decrease (p=0.004) in their cortisol awakening responses (CAR) after sleep restriction and a sustained elevation in afternoon/evening cortisol levels (p=0.008), as has been reported for men. Women in the luteal phase showed neither a depressed CAR, nor an increase in afternoon/evening cortisol levels. Secondary analyses examined the impact of sleep restriction on self-reported hunger and mood. Menstrual cycle phase dramatically altered the cortisol responses of healthy, young women to a single night of sleep restriction, implicating effects of spontaneous changes in endocrine status on adrenal responses to sleep loss.

  14. Midweek Increase in U.S. Summer Rain and Storm Heights, Suggests Air Pollution Invigorates Rainstorms

    Tropical Rainfall Measuring Mission (TRMM) satellite data show a significant midweek increase in summertime rainfall over the southeast U.S., due to afternoon intensification. TRMM radar data show a significant midweek increase in rain area and in the heights reached by afternoon storms. Weekly variations in model-reanalysis wind patterns over the region and in rain-gauge data are consistent with the satellite data. A midweek decrease of rainfall over the nearby Atlantic is also seen. EPA measurements of particulate concentrations show a midweek peak over much of the U.S. These observations are consistent with the theory that anthropogenic air pollution suppresses cloud-drop coalescence and early rainout during the growth of thunderstorms over land, allowing more water to be carried above the 0 C isotherm, where freezing yields additional latent heat, invigorating the storms--most dramatically evidenced by the shift in the midweek distribution of afternoon-storm heights--and producing large ice hydrometeors. The enhanced convection induces regional convergence, uplifting and an overall increase of rainfall. Compensating downward air motion suppresses convection over the adjacent ocean areas. Pre-TRMM-era data suggest that the weekly cycle only became strong enough to be detectable beginning in the 1980's. Rain-gauge data also suggest that a weekly cycle may have been detectable in the 1940's, but with peak rainfall on Sunday or Monday, possibly explained by the difference in composition of aerosol pollution at that time. This "weekend effect" may thus offer climate researchers an opportunity to study the regional climate-scale impact of aerosols on storm development and monsoon-like circulation.

    Full Text Available The behaviour of ostrich chicks bred in captivity was studied by using groups with 30 birds in five age groups: from 10 to 40 days of age; from 41 to 60 days of age; from 61 to 90 days of age; from 91 to 120 days of age and from 121 to 150 days of age. Six birds at each age were ringed around one of their feet and observed for four consecutive days for eight hours daily in three periods (in the morning, at noon and in the afternoon, following the "one-zero" method for sampling. The order for observation of behaviour of the six selected birds was performed randomly at every thirty minutes, totalling 16 periods or 80 minutes/bird/day. Fourteen types of behaviour were observed. There were differences among ages for behaviour like standing, walking, running, ingesting stones, ingesting feces, picking and attacking. Non-parametric-tests were used to analyse the behaviour according to age of the bird and to the periods of the day. There was a statistical difference between in the morning and at noon periods on behaviours standing, walking, eating ration and in litophagia, which were observed more frequently at the first hours of the day. When periods of the morning and afternoon were compared, the birds' age had a significant effect on behaviour sand bathing. When the periods noon/afternoon were compared, the behaviours which presented significant differences were walking, running, drinking water, eating ration, litophagia, coprophagia, dancing, sand bathing, whose occurrence was the highest during dusk. It was observed that the behaviour of young ostriches diverge according to the age and to day period.

    Full Text Available AIM To testify the fact about generalised untested belief that genital prolapse is more severe in the late afternoon as compared to the morning with the help of POPQ classification system. METHOD There is a generalised belief that prolapse is more severe at the end of the day as compared to the morning. We have planned this study to know whether this belief is correct or wrong. It is not possible to do this study with the help of old classification. So we decided to do it with the help of new classification, that is POPQ system. This is prospective study undertaken with permission of ethical committee consisting 48 patients attending gynec OPD of Dr. D. Y. Patil Medical Hospital. Each patient was examined with POPQ system twice, i.e. two visits and two sessions per visit, morning 9 am to 10 am and late afternoon 4 pm to 5 pm, which are our OPD timings. She was again called after one week and re-examined by the same person twice in a day as mentioned above. Findings were noted in different files and at the end of study data was analysed by applying statistical test of significance. RESULTS The study consisted of 48 patients. The POPQ exam stages were 47% stage II, 50% stage III, and 3% stage IV. There was no significant difference for the 9 POPQ exam measures between morning and afternoon exams. There was good agreement between AM and PM POPQ ordinal stages (Weighted Kappa value 0.76. CONCLUSION There is no difference between AM and PM POPQ exam results.

    Aerosol optical properties affect planetary radiative balance and depend on chemical composition, size distribution, and morphology. During the MILAGRO field campaign, we measured aerosol absorption and scattering in Mexico City using the Los Alamos aerosol photoacoustic (LAPA) instrument operating at 781 nm. The LAPA was mounted on-board the Aerodyne Research Inc. mobile laboratory, which hosted a variety of gaseous and aerosol instruments. During the campaign, the laboratory was moved to different sites, capturing spatial and temporal variability. Additionally, we collected ambient aerosols on Nuclepore filters for scanning electron microscopy (SEM) analysis. SEM images of selected filters were taken to study particle morphology. Between March 7th and 19th air was sampled at the top of Pico Tres Padres, a mountain on the north side of Mexico City. Aerosol absorption and scattering followed diurnal patterns related to boundary layer height and solar insulation. We report an analysis of aerosol absorption, scattering, and morphology for three days (9th, 11th and 12th of March 2006). The single scattering albedo (SSA, ratio of scattering to total extinction) showed a drop in the tens-of-minutes-to-hour time frame after the boundary layer grew above the sampling site. Later in the day the SSA rose steadily reaching a maximum in the afternoon. The SEM images showed a variety of aerosol shapes including fractal-like aggregates, spherical particles, and other shapes. The absorption correlated with the CO2 signal and qualitatively with the fraction of fractal-like particles to the total particle count. In the afternoon the SSA qualitatively correlated with a relative increase in spherical particles and total particle count. These observed changes in optical properties and morphology can be explained by the dominant contribution of freshly emitted particles in the morning and by secondary particle formation in the afternoon. SSA hourly averaged values ranged from ~0.63 in

    A smog index related to dosage (ppM/hr) of ozone was derived using data from the Baltimore-Washington metropolitan area for the months of June to Sept. 1972 and 1973. On the average, weekends have higher indices than weekdays. The 06:00 to 09:00 hr average concentrations of non-methane hydrocarbons are significantly higher during weekdays than during weekends. No relationship exists between these morning hydrocarbon levels and the afternoon peak O/sub 3/ concentration. There is some doubt on the effectiveness of early morning hydrocarbon emission control alone in an abatement program for photochemical oxidants.

    Many microbes in the soil environment experience micro-oxic or anoxic conditions for much of the late afternoon and night, which inhibit or prevent respiratory metabolism. To sustain the production of energy and maintain vital cellular processes during the night, organisms have developed numerous pathways for fermentative metabolism. This review discusses fermentation pathways identified for the soil-dwelling model alga Chlamydomonas reinhardtii, its ability to produce molecular hydrogen under anoxic conditions through the activity of hydrogenases, and the molecular flexibility associated with fermentative metabolism that has only recently been revealed through the analysis of specific mutant strains.

    The vertical columns of formaldehyde (HCHO) retrieved from two satellite instruments, the Global Ozone Monitoring Instrument-2 (GOME-2) on Metop-A and the Ozone Monitoring Instrument (OMI) on Aura, are used to constrain global emissions of HCHO precursors from open fires, vegetation and human activities in the year 2010. To this end, the emissions are varied and optimized using the ad-joint model technique in the IMAGESv2 global CTM (chem-ical transport model) on a monthly basis and at the model res-olution. Given the different local overpass times of GOME- 2 (09:30 LT) and OMI (13:30 LT), the simulated diurnal cy-cle of HCHO columns is investigated and evaluated against ground-based optical measurements at seven sites in Europe, China and Africa. The modeled diurnal cycle exhibits large variability, reflecting competition between photochemistry and emission variations, with noon or early afternoon max-ima at remote locations (oceans) and in regions dominated by anthropogenic emissions, late afternoon or evening max-ima over fire scenes, and midday minima in isoprene-rich re-gions. The agreement between simulated and ground-based columns is generally better in summer (with a clear after-noon maximum at mid-latitude sites) than in winter, and the annually averaged ratio of afternoon to morning columns is slightly higher in the model (1.126) than in the ground-based measurements (1.043).The anthropogenic VOC (volatile organic compound) sources are found to be weakly constrained by the inversions on the global scale, mainly owing to their generally minor contribution to the HCHO columns, except over strongly pol-luted regions, like China. The OMI-based inversion yields total flux estimates over China close to the bottom-up inven-tory (24.6 vs. 25.5 TgVOC yr-1 in the a priori) with, how-ever, pronounced increases in the northeast of China and re-ductions in the south. Lower fluxes are estimated based on GOME-2 HCHO columns (20.6 TgVOC yr-1), in

    This work reports on the trends of the daily afternoon (noon to midnight) maximum ozone concentrations at 15 of the 16 stations of the Swiss air quality monitoring network (NABEL) during the period 1992-2002. The use of numerous meteorological parameters and additional data allowed a detailed seasonal analysis of the influence of the weather on the ozone maxima at the different stations. An analysis of covariance (ANCOVA) was performed separately for each station and season in order to detect the parameters which best explain the variability of the daily ozone maximum concentrations. During the warm seasons (summer and spring) the most explanatory parameters are those related to the ozone production, in particular the afternoon temperature. In winter, the most explanatory variables are the ones influencing the vertical mixing and thus the ozone destruction by titration with NO and dry deposition, like the afternoon global radiation. The trends of both the measured and meteorologically corrected ozone maxima were calculated. The year-to-year variability in the ozone maxima was lowered by a factor of 3 by the meteorological correction. Significantly positive trends of corrected ozone maxima of 0.3 - 1.1 ppb/year were found at the low altitude stations in winter and autumn as well as at Lausanne - urban station - in all the seasons, mainly due to the lower loss of ozone by reaction with NO as a consequence of the decreased emissions of primary pollutants during the 90s. This could be partially confirmed by the lower trends of OX (sum O3 of and NO2) maxima compared to the trends in ozone maxima. The absence of negative trends of the median or mean ozone maxima north of the Alps in summer suggests that the decrease in the emissions of ozone precursors did not have a strong impact on the afternoon maximum ozone concentrations during the last decade. In contrast to the project TOSS (Trends of Ozone in Southern Switzerland), no significantly negative trends of ozone maxima

    2010-01-01

    Early in the morning of 1 February 2010 (UTC; early afternoon 31 January 2010 local time), continuous Global Positioning System (GPS) and tilt instruments detected a slow slip event (SSE) on the south flank of Kilauea volcano, Hawaii. The SSE lasted at least 36 hours and resulted in a maximum of about 3 centimeters of seaward displacement. About 10 hours after the start of the slip, a flurry of small earthquakes began (Figure 1) in an area of the south flank recognized as having been seismically active during past SSEs [Wolfe et al., 2007], suggesting that the February earthquakes were triggered by stress associated with slip [Segall et al., 2006].

    In this report, we show the rapid assessment of black tea as potential fuel to power up nanopower systems using a microsized, simplistic and sustainable air-cathode microbial fuel cell. It was found that tea produced more power compared with traditional sodium acetate media due in part to its acidophilic pH and its higher organics content. Although high internal resistance remains a big concern, this simple, curiosity-driven experiment gave us the preliminary results to say that energy could be extracted from the reuse of waste resources such the collection of our afternoon-tea\\'s leftovers.

    As a sole canoe navigated the lazy flatwater bends of Maryland's Blackwater River on a perfect summer afternoon last June, fish jumped, dragonflies zigged across the open water and through the tall grass in the brackish tidal marshland, and in the distance several young eagles drifted in the blue sky. On the way back to the boat landing, a furry mammal casually paddled across the water: too big for a muskrat and not quite a beaver, the creature slinked into the marsh vegetation bordering the river. Then another appeared and perhaps a half-dozen more that day, an abundance of wildlife.

  4. Seawifs Technical Report Series. Volume 2: Analysis of Orbit Selection for Seawifs: Ascending Versus Descending Node

    1992-01-01

    Due to range safety considerations, the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) ocean color instrument may be required to be launched into a near-noon descending node, as opposed to the ascending node used by the predecessor sensor, the Coastal Zone Color Scanner (CZCS). The relative importance of ascending versus descending near-noon orbits was assessed here to determine if descending node will meet the scientific requirements of SeaWiFS. Analyses focused on ground coverage, local times of coverage, solar and viewing geometries (zenith and azimuth angles), and sun glint. Differences were found in the areas covered by individual orbits, but were not important when taken over a 16 day repeat time. Local time of coverage was also different: for ascending node orbits the Northern Hemisphere was observed in the morning and the Southern Hemisphere in the afternoon, while for descending node orbits the Northern Hemisphere was observed in the afternoon and the Southern in the morning. There were substantial differences in solar azimuth and spacecraft azimuth angles both at equinox and at the Northern Hemisphere summer solstice. Negligible differences in solar and spacecraft zenith angles, relative azimuth angles, and sun glint were obtained at the equinox. However, large differences were found in solar zenith angles, relative azimuths, and sun glint for the solstice. These differences appeared to compensate across the scan, however, an increase in sun glint in descending node over that in ascending node on the western part of the scan was compensated by a decrease on the eastern part of the scan. Thus, no advantage or disadvantage could be conferred upon either ascending node or descending node for noon orbits. Analyses were also performed for ascending and descending node orbits that deviated from a noon equator crossing time. For ascending node, afternoon orbits produced the lowest mean solar zenith angles in the Northern Hemisphere, and morning orbits produced

    F-region electron density depletions associated with main ionization troughs in the high-latitude ionosphere are studied using EISCAT CP3 data of meridian scanning experiments. The troughs in our observations are found to appear mainly in dusk sector, extending from late afternoon to pre-midnight, with higher occurrence rate during equinox and winter. Simultaneous ion drift velocity in F-region shows that the main trough minimm is mostly located at the equator ward edge of the plasma convection flow, rather than in the r~ion where the largest ion flow are observed.

    Of those spousal caregivers who identified a time when they most needed assistance, morning or afternoon time periods appeared to be most problematic. Spousal caregivers who reported receiving respite time on the weekends identified adult children as the informal support person most often available. However, more than half of the caregivers reported having no respite time during the weekend. Differences in the ways spousal caregivers spent their respite time on the weekends, if available, varied by gender, length of tenure as a caregiver, and age. PMID:10461273

    Measurements of aerosol absorption were obtained as part of the MAX-Mex component of the MILAGRO field campaign at site T0 (Instituto Mexicano de Petroleo in Mexico City) by using a 7-channel aethalometer (Thermo- Anderson) during the month of March, 2006. The absorption measurements obtained in the field at 370, 470, 520, 590, 660, 880, and 950 nm were used to determine the aerosol Angstrom absorption exponents by linear regression. Since, unlike other absorbing aerosol species (e.g. humic like substances, nitrated PAHs), black carbon absorption is relatively constant from the ultraviolet to the infrared with an Angstrom absorption exponent of -1 (1), a comparison of the Angstrom exponents can indicate the presence of aerosol components with an enhanced UV absorption over that expected from BC content alone. The Angstrom exponents determined from the aerosol absorption measurements obtained in the field varied from - 0.7 to - 1.3 during the study and was generally lower in the afternoon than the morning hours, indicating an increase in secondary aerosol formation and photochemically generated UV absorbing species in the afternoon.

    Yeung, Ellen W.; Davis, Mary C.; Aiken, Leona S.; Tennen, Howard A.

    2014-01-01

    Background Fatigue is a debilitating symptom of fibromyalgia (FM) that has limited treatment options. Some evidence, however, has linked positive social engagement with reduced within-day fatigue. Purpose This study elaborated longitudinal within-day and across-day relations between FM fatigue and social enjoyment. Methods 176 women with FM completed 21-day automated diaries assessing morning and end-of-day fatigue, and both afternoon social enjoyment and stress within two social domains: non-spousal and spousal. Results In the non-spousal domain, analysis supported a mediational path from lower morning fatigue to higher afternoon social enjoyment, which predicted lower end-of-day fatigue, and subsequently, lower next-morning fatigue. Enjoyment exerted a greater impact on within-day fatigue than did stress. Patterns in the spousal domain were similar, but the mediated path was nonsignificant. Conclusions Positive social engagement offers relief from FM fatigue that carries over across days and may provide an additional target to enhance the effectiveness of current interventions.

  16. Observational analysis of the interaction between a baroclinic boundary and supercell storms on 27 April 2011

    Science.gov (United States)

    Sherrer, Adam Thomas

    A thermal boundary developed during the morning to early afternoon hours on 27 April as a result of rainfall evaporation and shading from reoccurring deep convection. This boundary propagated to the north during the late afternoon to evening hours. The presence of the boundary produced an area more conducive for the formation of strong violent tornadoes through several processes. These processes included the production of horizontally generated baroclinic vorticity, increased values in storm-relative helicity, and decreasing lifting condensation level heights. Five supercell storms formed near and/or propagated alongside this boundary. Supercells that interacted with this boundary typically produced significant tornadic damage over long distances. Two of these supercells formed to the south (warm) side of the boundary and produced a tornado prior to crossing to the north (cool) side of the boundary. These two storms exhibited changes in appearance, intensity, and structure. Two other supercells formed well south of the boundary. These two storms remained relatively weak until they interacted with the boundary. These storms then rapidly intensified and produced tornadoes. Supercells that formed well into the cool side of the boundary either did not produce tornadoes or the tornadoes were determined to be weak in nature.

  17. The energy expenditure of sedentary behavior: a whole room calorimeter study.

    Directory of Open Access Journals (Sweden)

    Robert L Newton

    Full Text Available It has recently been recommended that sedentary behavior be defined as sitting or reclining activities expending less than 1.5 metabolic equivalents (METs, which is distinct from the traditional viewpoint based on insufficient moderate-vigorous activity or formal exercise. This study was designed to determine the energy expenditure associated with common sedentary behaviors. Twenty-five African American adults (BMI 27.8 ± 5.5 participated in the metabolic chamber study. Participants entered the metabolic chamber in the morning and their basal metabolic rate was estimated. They were fed breakfast and then engaged in four different sedentary behaviors sequentially, lasting 30 minutes each. The activities included reclining, watching TV, reading, and typing on a computer. In the afternoon, the participants were fed lunch and then the activities were repeated. The results show that the energy expenditure values between the morning and afternoon sessions were not significantly different (p = .232. The mean energy expenditure of postprandial reclining (0.97 METs was slightly, but significantly, lower than postprandial watching TV (p = .021 and typing (p<.001. There were no differences in energy cost (1.03-1.06 METs between the seated (i.e., reading, typing, watching TV sedentary activities. The energy expenditure of several common sedentary behaviors was approximately 1.0 METs in the postprandial state. The results support the conclusion that the average energy cost of common sedentary behaviors is narrowly banded around 1.0 METs in the postprandial state.

    This study examined lightning activity and its relationship to precipitation and convective available potential energy (CAPE) in South China during 2001-12, based on data from the Guangdong Lightning Location System, the Tropical Rainfall Measuring Mission satellite, and the ERA-Interim dataset. Two areas of high lightning density are identified: one over the Pearl River Delta, and the other to the north of Leizhou Peninsula. Large peak-current cloud-to-ground (LPCCG) lightning (>75 kA) shows weaker land-offshore contrasts than total CG lightning, in which negative cloud-to-ground (NCG) lightning occurs more prominently than positive cloud-to-ground (PCG) lightning on land. While the frequency of total CG lightning shows a main peak in June and a second peak in August, the LPCCG lightning over land shows only a single peak in June. The ratio of positive LPCCG to total lightning is significantly greater during February-April than during other times of the year. Diurnally, CG lightning over land shows only one peak in the afternoon, whereas CG lightning offshore shows morning and afternoon peaks. The rain yield per flash is on the order of 107-108 kg per flash across the analysis region, and its spatial distribution is opposite to that of lightning density. Our data show that lightning activity over land is more sensitive than that over offshore waters to CAPE. The relationships between lightning activity and both precipitation and CAPE are associated with convection activity in the analysis region.

    Full Text Available Objectives. This study investigated the activity behavior of patients with COPD in detail compared to asymptomatic controls, and the relationship between subjective and objective activities (awareness, and readiness to change activity behavior. Methods. Thirty-nine patients with COPD (66.0 years; FEV1% predicted: 44.9% and 21 healthy controls (57.0 years participated. Objective daily activity was assessed by accelerometry and expressed as amount of activity in counts per minute (cpm. Patients' baseline subjective activity and stage of change were assessed prior to measurements. Results. Mean daily activity in COPD patients was significantly lower compared to the healthy controls ( cpm versus  cpm, . COPD patients showed a temporary decrease in objective activities in the early afternoon. Objective and subjective activities were significantly moderately related and most patients (55.3% were in the maintenance phase of the stages of change. Conclusions. COPD patients show a distinctive activity decrease in the early afternoon. COPD patients are moderately aware of their daily activity but regard themselves as physically active. Therefore, future telemedicine interventions might consider creating awareness of an active lifestyle and provide feedback that aims to increase and balance activity levels.

    2010-12-01

    Here, we present the design and implementation of the Prospective Graduate Student Workshop (PGSW) in Ocean Sciences, a new teaching venue developed within the University of California's Center for Adaptive Optics (CfAO). The one-day workshop introduced undergraduate and community college students interested in pursuing graduate school to the field of ocean sciences through a series of inquiry-based activities. Throughout the activity design process, two important themes were emphasized; 1) physical, chemical, and biological properties are tightly coupled in the ocean; 2) ocean sciences is a highly inter-disciplinary field that includes scientists from diverse backgrounds. With these ideas in mind the workshop was split into two activities, morning and afternoon, each of which concentrated on teaching certain process skills thought to be useful for prospective graduate students. The morning covered density and mixing in the ocean and the afternoon was focused on phytoplankton and how they experience the ocean as a low Reynolds number environment. Attendees were instructed to complete pre- and post-activity questionnaires, which enabled assessment of individual components and the workshop as a whole. Response was very positive, students gained knowledge about ocean sciences, scientific inquiry, and graduate school in general, and most importantly had fun voluntarily participating in science on a Sunday.

    Repetitive movement patterns are commonly observed in zoo elephants. The extent to which these behaviors constitute a welfare concern varies, as their expression ranges from stereotypies to potentially beneficial anticipatory behaviors. Nevertheless, their occurrence in zoo animals is often viewed negatively. To better identify conditions that prompt their performance, observations were conducted on six African elephants (Loxodonta africana) at the North Carolina Zoo. Individuals spent most of their time engaged in feeding, locomotion, resting, and repetitive behavior. Both generalized estimating equation and zero-inflated negative binomial models were used to identify factors associated with increased rates of repetitive behavior. Time of day in conjunction with location on- or off-exhibit best explained patterns of repetitive behavior. Repetitive behaviors occurred at a lower rate in the morning when on-exhibit, as compared to afternoons on-exhibit or at any time of day off-exhibit. Increased repetitive behavior rates observed on-exhibit in the afternoon prior to the evening transfer and feeding were possibly anticipatory responses towards those events. In contrast, consistently elevated frequencies of repetitive behavior off-exhibit at all times of day could be related to differences in exhibit complexity between off-exhibit and on-exhibit areas, as well as a lack of additional foraging opportunities. Our study contributes valuable information on captive elephant behavior and represents a good example of how behavioral research can be employed to improve management of zoo animals. PMID:25919392

    The present study examined effects of simulated air travel on physical performance. In a randomized crossover design, 10 physically active males completed a simulated 5-h domestic flight (DOM), 24-h simulated international travel (INT), and a control trial (CON). The mild hypoxia, seating arrangements, and activity levels typically encountered during air travel were simulated in a normobaric, hypoxic altitude room. Physical performance was assessed in the afternoon of the day before (D - 1 PM) and in the morning (D + 1 AM) and afternoon (D + 1 PM) of the day following each trial. Mood states and physiological and perceptual responses to exercise were also examined at these time points, while sleep quantity and quality were monitored throughout each condition. Sleep quantity and quality were significantly reduced during INT compared with CON and DOM (P  0.05). Compared with baseline, physiological and perceptual responses to exercise, and mood states were exacerbated following the INT trial (P < 0.05). Attenuated intermittent-sprint performance following simulated international air travel may be due to sleep disruption during travel and the subsequent exacerbated physiological and perceptual markers of fatigue.

    The aim of this work was the estimation of microbial contamination of the air in "small gastronomy point". The study included three places, which have been separated on the ground of their function: 1. area of subsidiaries, 2. area of distribution (sale and serving meal), 3. area of consumption. The total numbers of aerobic mesophilic bacteria, yeasts and moulds were determined by sedimentation method. Taxonomy units of fungal aerosol were also estimated. The samples of air were collected in 16 investigation points in the morning (8-8.30) and in the afternoon (14-14.30). Four series of measurements were carried out and in general 128 of air samples were tested. The results showed that numbers of bacteria, yeasts and moulds were variable and received respectively 30-3397, 0-254 and 0-138 cfu x m(-3). Microbial contamination of air changed depending on area character (the highest average count of bacteria occurred in the air of consumption area and fungi in subsidiaries area), time of a day (contamination of the air increased in the afternoon) and determination date. Only in single samples the numbers of bacteria and fungi were higher than recommended level. Pigmentary bacteria had high participation in total count of bacteria and filamentous fungi were represented mostly by Penicillium sp. and Cladosporium sp.

    2002-02-01

    The 2001 meeting entitled ''Genetic Recombination and Genome Rearrangements'' was held July 21-26 in Snowmass, Colorado. The goal of the meeting was to bring together scientists using diverse approaches to study all aspects of genetic recombination. This goal was achieved by integrating talks covering the genetics, biochemistry and structural biology of homologous recombination, site-specific recombination, and nonhomologous recombination. The format of the meeting consisted of a keynote address on the opening evening, two formal plenary sessions on each of the four full meeting days, a single afternoon workshop consisting of short talks chosen from among submitted abstracts, and afternoon poster sessions on each of the four full meeting days. The eight plenary session were entitled: (1) Recombination Mechanisms, (2) Prokaryotic Recombination, (3) Repair and Recombination, (4) Site-specific Recombination and Transposition, (5) Eukaryotic Recombination I, (6) Genome Rearrangements, (7) Meiosis, and (8) Eukaryotic Recombination II. Each session included a mix of genetic, biochemical and structural talks; talks were limited to 20 minutes, followed by 10 minutes of very lively, general discussion. Much of the data presented in the plenary sessions was unpublished, thus providing attendees with the most up-to-date knowledge of this rapidly-moving field.

    Isoetes sinensis Palmer (Isoetaceae) is an aquatic or amphibious plant that is critically endangered in China. Previous studies have revealed the crassulacean acid metabolism (CAM)-like photosynthetic pathway occurs commonly in submerged leaves in genus Isoetes. Water chemistry parameters and the titratable acidity content of the plant extract were measured from samples obtained in the early morning (7:00) and late afternoon (15=00) from two I.sinensis populations in China. One population occurs in the eulittoral zone of a freshwater tidal river at low elevation (134 m) and another occurs in a densely vegetated, high elevation (1 100 m) alpine shallow pool. Significant difference sin pH and titratable acidity of the plant extract were detected between the morning and afternoon samples. These changes are associated with diurnal changes in water chemistry. Our results provide the first evidence for the existence of the CAM pathway in the East Asian endemic Isoetes sinensis Palmer.The magnitude of fluctuations in the titratable acidity of the plant extract may be correlated with the severe carbon limitation imposed on the plants by its aquatic habitat.

    Full Text Available Optimizing physical activity in childhood is needed for prevention of disease and for healthy social and psychological development. There is limited research examining how segmented school physical activity patterns relate to a child achieving optimal physical activity levels. The purpose of this study was to examine the predictive relationship between step counts during specific school segments and achieving optimal school (6,000 steps/day and daily (12,000 steps/day step counts in children. Participants included 1,714 school-aged children (mean age = 9.7±1.0 years recruited across six elementary schools. Physical activity was monitored for one week using pedometers. Generalized linear mixed effects models were used to determine the adjusted odds ratios (ORs of achieving both school and daily step count standards for every 1,000 steps taken during each school segment. The school segment that related in strongest way to a student achieving 6,000 steps during school hours was afternoon recess (OR = 40.03; P<0.001 and for achieving 12,000 steps for the entire day was lunch recess (OR = 5.03; P<0.001. School segments including lunch and afternoon recess play an important role for optimizing daily physical activity in children.

  9. Haze event monitoring and investigation in Penang Island, Malaysia using a ground-based backscatter Lidar

    International Nuclear Information System (INIS)

    During 24th July 2013 to 1st August 2013, a haze event struck Penang Island, causing the visibility to decrease and increase in Air Pollution Index (API). A ground-based backscatter Lidar, operate at 355 nm which was setup at the roof top of the School of Physics, Universiti Sains Malaysia. It was used to monitor and investigate the haze event. For this work, we studied the daytime variation of the aerosol intensity, distribution, planetary boundary layer (PBL) height and the aerosol optical depth (AOD) values during these days. We found that the aerosol are very intense during the first two days of the haze event and slowly decline as time passed. Finally the haze event died off on 1st August 2013. As for daily aerosol distribution, aerosols are generally more intense during the afternoon. Its intensity is slightly lower in the morning and evening. Similar trends were observed for AOD values as they increase from morning to afternoon and slowly decrease in the evening. Most aerosols are found contained below the PBL which generally found at around 1000 – 2000 m in height

    AIM: To compare(using the Ottawa Bowel Preparation Scale) the efficacy of split-dose vs morning administration of polyethylene glycol solution for colon cleansing in patients undergoing colonoscopy, and to assess the optimal preparation-to-colonoscopy interval.METHODS: Single-centre, prospective, randomized, investigator-blind stud in an academic tertiarycare centre. Two hundred patients requiring elective colonoscopy were assigned to receive one of the two preparation regimens(split vs morning) prior to colonoscopy. Main outcome measurements were bowel preparation quality and patient tolerability.RESULTS: Split-dose regimen resulted in better bowel preparation compared to morning regimen [Ottawascore mean 5.52(SD 1.23) vs 6.02(1.34); P = 0.017]. On subgroup analysis, for afternoon procedures, both the preparations were equally effective(P = 0.756). There was no difference in tolerability and compliance between the two regimens.CONCLUSION: Overall, previous evening- same morning split-dosing regimen results in better bowel cleansing for colonoscopy compared to morning preparation. For afternoon procedures, both schedules are equally effective; morning preparation may be more convenient to the patient.

    Cerebral autoregulation controls cerebral blood flow under changing cerebral perfusion pressure. Standards for measurement and analysis of dynamic cerebral autoregulation (dCA) are lacking. In this study, dCA reproducibility, quantified by intraclass correlation coefficient, is evaluated for different methodological approaches of transfer function analysis (TFA) and compared with multimodal pressure flow analysis (MMPF). dCA parameters were determined in 19 healthy volunteers during three 15-min lasting epochs of spontaneous breathing. Every spontaneous breathing epoch was followed by 5 min of paced breathing at 6 cycles/min. These six measurements were performed in both a morning and an afternoon session. Analysis compared raw data pre-processing by mean subtraction versus smoothness priors detrending. The estimation of spectral density was either performed by averaging of subsequent time windows or by smoothing the spectrum of the whole recording. No significant influence of pre-processing and spectral estimation on dCA parameters was found. Therefore, there seems to be no need to prescribe a specific signal-processing regime. Poor reproducibility of gain and phase was found for TFA as well as for MMPF. Based on reproducibility, no preference can be made for morning versus afternoon measurements, neither for spontaneous versus paced breathing. Finally, reproducibility results are not in favour of TFA or MMPF.

    The present study examined effects of simulated air travel on physical performance. In a randomized crossover design, 10 physically active males completed a simulated 5-h domestic flight (DOM), 24-h simulated international travel (INT), and a control trial (CON). The mild hypoxia, seating arrangements, and activity levels typically encountered during air travel were simulated in a normobaric, hypoxic altitude room. Physical performance was assessed in the afternoon of the day before (D - 1 PM) and in the morning (D + 1 AM) and afternoon (D + 1 PM) of the day following each trial. Mood states and physiological and perceptual responses to exercise were also examined at these time points, while sleep quantity and quality were monitored throughout each condition. Sleep quantity and quality were significantly reduced during INT compared with CON and DOM (P  0.05). Compared with baseline, physiological and perceptual responses to exercise, and mood states were exacerbated following the INT trial (P sleep disruption during travel and the subsequent exacerbated physiological and perceptual markers of fatigue.

    Geneva, 23 November 2009. Today the LHC circulated two beams simultaneously for the first time, allowing the operators to test the synchronization of the beams and giving the experiments their first chance to look for proton-proton collisions. With just one bunch of particles circulating in each direction, the beams can be made to cross in up to two places in the ring. From early in the afternoon, the beams were made to cross at points 1 and 5, home to the ATLAS and CMS detectors, both of which were on the lookout for collisions. Later, beams crossed at points 2 and 8, ALICE and LHCb. “It’s a great achievement to have come this far in so short a time,” said CERN Director General Rolf Heuer. “But we need to keep a sense of perspective – there’s still much to do before we can start the LHC physics programme.” Beams were first tuned to produce collisions in the ATLAS detector, which recorded its first candidate for collisions at 14:22 this afternoon. Later, the beams were optimised for CMS. In the ...

  8. An evidence for prompt electric field disturbance driven by changes in the solar wind density under northward IMF Bz condition

    Before the onset of a geomagnetic storm on 22 January 2012 (Ap = 24), an enhancement in solar wind number density from 10/cm3 to 22/cm3 during 0440-0510 UT under northward interplanetary magnetic field (IMF Bz) condition is shown to have enhanced the high-latitude ionospheric convection and also caused variations in the geomagnetic field globally. Conspicuous changes in ΔX are observed not only at longitudinally separated low-latitude stations over Indian (prenoon), South American (midnight), Japanese (afternoon), Pacific (afternoon) and African (morning) sectors but also at latitudinally separated stations located over high and middle latitudes. The latitudinal variation of the amplitude of the ΔX during 0440-0510 UT is shown to be consistent with the characteristics of prompt penetration electric field disturbances. Most importantly, the density pulse event caused enhancements in the equatorial electrojet strength and the peak height of the F layer (hmF2) over the Indian dip equatorial sector. Further, the concomitant enhancements in electrojet current and F layer movement over the dip equator observed during this space weather event suggest a common driver of prompt electric field disturbance at this time. Such simultaneous variations are found to be absent during magnetically quiet days. In absence of significant change in solar wind velocity and magnetospheric substorm activity, these observations point toward perceptible prompt electric field disturbance over the dip equator driven by the overcompression of the magnetosphere by solar wind density enhancement.

    The usefulness of spot determination of urinary cortisol in the screening of Cushing's syndrome was evaluated by measuring the cortisol concentration in randomly sampled urine in 68 normal subjects and in 9 patients with Cushing's syndrome. The urinary cortisol concentration in the morning was significantly higher in patients with Cushing's syndrome but some overlap existed between normal subjects and patients with Cushing's syndrome. In contrast, there was a clear discrimination between two groups when urinary cortisol was measured in the late evening: urinary cortisol was lower than 75 micrograms per gram creatinine (microgram/gCr) in normal subjects but higher than 150 micrograms/gCr in patients with Cushing's syndrome. When 1 mg dexamethasone was administered at 2300 h in the evening, spot urinary cortisol the next morning was less than 80 micrograms/gCr in normal subjects while it was above 100 micrograms/gCr in patients with Cushing's syndrome. Dexamethasone-induced suppression of urinary cortisol in normal subjects lasted until late in the afternoon, which allows sampling of urine at any time in the morning and possibly in the afternoon. These results suggest the usefulness of spot determination of urinary cortisol in the screening of Cushings' syndrome.

  10. Impact of land convection on temperature diurnal variation in the tropical lower stratosphere inferred from COSMIC GPS radio occultations

    2013-07-01

    Full Text Available Following recent studies evidencing the influence of deep convection on the chemical composition and thermal structure of the tropical lower stratosphere, we explore its impact on the temperature diurnal variation in the upper troposphere and lower stratosphere using the high-resolution COSMIC GPS radio-occultation temperature measurements spanning from 2006 through 2011. The temperature in the lowermost stratosphere over land during summer displays a marked diurnal cycle characterized by an afternoon cooling. This diurnal cycle is shown collocated with most intense land convective areas observed by the Tropical Rainfall Measurement Mission (TRMM precipitation radar and in phase with the maximum overshooting occurrence frequency in late afternoon. Two processes potentially responsible for that are identified: (i non-migrating tides, whose physical nature is internal gravity waves, and (ii local cross-tropopause mass transport of adiabatically cooled air by overshooting turrets. Although both processes can contribute, only the lofting of adiabatically cooled air is well captured by models, making it difficult to characterize the contribution of non-migrating tides. The impact of deep convection on the temperature diurnal cycle is found larger in the southern tropics, suggesting more vigorous convection over clean rain forest continents than desert areas and polluted continents in the northern tropics.

    Full Text Available Technologies that improve productivity are essentials for competitiveness in the pork market. The consumer market is always requiring information about the technologies applied in swine production, mainly from the perspective of animal welfare. The aim of this study was to evaluate the influence of lighting on performance, behavioral and physiological characteristics in finishing pigs. Thirty-six pigs were distributed in a completely randomized design with three treatments and six replications. The animals were subjected to three light programs: natural light (NL, 16 hours of light and eight hours of dark (16L:8D and 23 hours of light and one hour of dark (23L:1D for 28 days. Daily feed intake (DFI, average daily gain (ADG and feed conversion (FC were evaluated. The physiological parameters evaluated were rectal temperature (RT, respiratory rate (RR and surface temperature (ST. The behavioral standards observed were: standing, lying, eating, drinking, sniffing, interacting, sitting, urinating and defecating. The lighting programs did not affect animal performance. However, pigs that received 23L:1D, showed, in the afternoon, ST upper than others treatments. Providing supplemental light promoted the elevation of RR, also in the afternoon. The RT was not influenced by treatments. The extended light program altered the behavior of the animals, which animals were most active, especially at night. Anyway, there was no improvement or reduction of the performance with the use of different lighting programs for finishing pigs.

    H2O2 and CH3OOH were measured during the cruise sponsored by Intergovernmental Oceanographic Commission (IOC). Experiments were made from Osaka to Honolulu covering the North Pacific on the research vessel MelVill belonging to Scripps Institution of Oceanography in May - June 2002. Gaseous hydroperoxides were extracted onto aqueous solution using a continuous glass coil. Collected samples were analyzed by a high performance liquid chromatography (HPLC) with fluorescence detector using postcolumn enzyme derivatization. It was the first measurement of species specific hydroperoxides on the ship, particularly CH_3OOH. The concentration of H_2O_2 and CH_3OOH increased from 0.93 ±0.48 ppbv and 0.27±0.40 ppbv at higher latitudes (˜50^oN) to 2.05±0.87 ppbv and 2.47±0.76 ppbv at low latitudes (˜24^oN). Hydroperoxides showed a typical diurnal variation with maximum in the late afternoon and minimum right before sunrise. In general, hydroperoxide and ozone concentrations were negatively correlated, particularly in the afternoon. There was no clear minimum and concentrations were higher than 1 ppbv during the night. Moreover, H_2O_2 concentrations were gradually increased even after the sunset. Consequently, other source than known photochemical production was proposed that hydroperoxides could be generated from the ozonlysis of alkene emitted from the ocean.

  13. Observations of cold magnetospheric ions at geosynchronous orbit during times of high activity

    International Nuclear Information System (INIS)

    Flowing, cold magnetospheric ions have been observed in conjunction with geosynchronous orbit magnetopause crossings since the earliest ATS and OGO missions. The authors have reported on the occurrence and convection of low-energy (10-100 eV) ions seen by multiple satellites in association with geosynchronous orbit magnetopause and low-latitude boundary layer (LLBL) encounters. More generally, Los Alamos 3-D plasma instruments observe these ions following storm sudden commencements (SSCs), when activity levels are high. The ions appear to be convecting radially outward and usually westward at speeds of a few to several tens of kilometers per second. Often the energy spectra reveal peaks at energies appropriate for cold convecting H+, He+ and O+. The occurrence frequency distribution of these dense cold ions is peaked near 1400 LT, with an overall range from 1000 to beyond 1800 LT. This local time distribution is greatly skewed from the overall plasmaspheric distribution, which peaks closer to 1800 LT. Multisatellite observations show that the ions are seen first at late afternoon local times and then at progressively earlier and earlier local times (though usually no earlier than 1000 LT). This apparent evolution in local time suggests that the late-afternoon plasmaspheric plasma moves out and dawnward during times of increased magnetospheric activity. The three-satellite observations also allow the authors to track cold plasma convection at multiple points in the magnetosphere, and potentially provide a glimpse of the large-scale convection pattern

    A regional climate model (RCM) has been applied to simulate the diurnal variations of the Asian summer monsoon during the early summer period. The ERA40 reanalysis data and the TRMM precipitation data are used to evaluate the performance of the model. The 5-year simulations show that the RCM could simulate well the diurnal cycle of the monsoon circulation over the region. A strong diurnal variation of circulation over the Tibetan Plateau (TP) can be observed at the 500-hPa level, with strong convergence and upward motion in the late afternoon. The diurnal variation of the 500-hPa relative vorticity over the TP associated with the corresponding diurnal variation of convergence may lead to the formation of a prominent plateau-scale cyclonic circulation over the TP during the evening to midnight period. The simulated diurnal variation of precipitation over land is generally better than that over the ocean, particularly over the regions close to the TP such as the Bangladesh region in the southern flank of the TP, where the well-known nocturnal maximum in precipitation is well captured by the RCM. However, the late-afternoon maximum in precipitation over the Southeast Asia region is not well simulated by the RCM. The model results suggest that the diurnal variation of precipitation over the southern flank of the TP is associated with the strong diurnal variation in the circulation over the TP. (orig.)

  18. Food selectivity and diet switch can explain the slow feeding of herbivorous coral-reef fishes during the morning.

    Directory of Open Access Journals (Sweden)

    Ruth Khait

    Full Text Available Most herbivorous coral-reef fishes feed slower in the morning than in the afternoon. Given the typical scarcity of algae in coral reefs, this behavior seems maladaptive. Here we suggest that the fishes' slow feeding during the morning is an outcome of highly selective feeding on scarcely found green algae. The rarity of the food requires longer search time and extended swimming tracks, resulting in lower bite rates. According to our findings by noon the fish seem to stop their search and switch to indiscriminative consumption of benthic algae, resulting in apparent higher feeding rates. The abundance of the rare preferable algae gradually declines from morning to noon and seems to reach its lowest levels around the switch time. Using in situ experiments we found that the feeding pattern is flexible, with the fish exhibiting fast feeding rates when presented with ample supply of preferable algae, regardless of the time of day. Analyses of the fish's esophagus content corroborated our conclusion that their feeding was highly selective in the morning and non-selective in the afternoon. Modeling of the fishes' behavior predicted that the fish should perform a diel diet shift when the preferred food is relatively rare, a situation common in most coral reefs found in a warm, oligotrophic ocean.

    Full Text Available In the first experiment 360 Pannon White kits from 45 litters were divided into 3 groups. The kits in group SS were suckled once a day during the first 35 days of life (traditional method of nursing. Group DD was raised by 2 does and the kits were suckled both in the morning and in the evening until 35 days of age. The kits of the 3 rd group (D0 were suckled twice a day for 23 days, after which they were weaned. Rabbits which were suckled twice a day consumed 89 % more milk until 23 days of age than those of the SS kits. In the second experiment authors used different management systems, to investigate the possibilities of “double-suckling”. Both nulliparous as multiparous does were treated to induce pseudopregnancy (by means of GnRH. They were used as second doe and suckled the kits in the afternoon. Pseudopregnant does produced milk (nulliparous does less than does which had previously produced litters, but in conditions of controlled suckling they were not willing to suckle the young. In a third experiment, does (n=44 were inseminated 11 days after kindling. Weaning was performed at the age of 21 days and does could systematically serve as second mother for the litters born at the same day. The “additional” does that nursed the young in the afternoon produced 65 % of the milk quantity produced by the natural mother between days 0 and 21.

    Full Text Available In this study we aimed to evaluate the physiological variables of sheep under the influence of Piauí semiarid environment. We used ten Santa Ines rams with black coat. The study was conducted at the small ruminants sector of the Federal University of Piauí, Campus Professora Cinobelina Elvas. Respiratory and cardiac frequencies, rectal temperature and sweating rate were measured.  Temperature, air relative humidity and globe temperature and humidity index were recorded at the Campus weather station. There was a significant difference for all the meteorological variables so that the highest values were observed for the afternoon shift, except for air relative humidity (33.52%. For physiological variables significant effect was observed for respiratory and cardiac frequencies and higher values of these variables were found in the morning shift, with 49,50 breath/min and 89,52 beats/min, respectively. For rectal temperature, significant effect was observed, with the highest values for the afternoon shift (39,92°C. We can notice that the animals needed to activate their physiological variables to keep their bodies in thermoneutral zone.

  1. Isolating effects of terrain and soil moisture heterogeneity on the atmospheric boundary layer: Idealized simulations to diagnose land-atmosphere feedbacks

    2015-06-01

    The effects of terrain, soil moisture heterogeneity, subsurface properties, and water table dynamics on the development and behavior of the atmospheric boundary layer are studied through a set of idealized numerical experiments. The mesoscale atmospheric model Advanced Regional Prediction System (ARPS) is used to isolate the effects of subsurface heterogeneity, terrain, and soil moisture initialization. The simulations are initialized with detailed soil moisture distributions obtained from offline spin-ups using a coupled surface-subsurface model (ParFlow-CLM). In these idealized simulations, we observe that terrain effects dominate the planetary boundary layer (PBL) development during early morning hours, while the soil moisture signature overcomes that of terrain during the afternoon. Water table and subsurface properties produce a similar effect as that of soil moisture as their signatures (reflected in soil moisture profiles, energy fluxes, and evaporation at the land surface) can also overcome that of terrain during afternoon hours. This is mostly clear for land surface energy fluxes and evaporation at the land surface. We also observe the coupling between water table depth and planetary boundary layer depth in our cases is strongest within wet-to-dry transition zones. This extends the findings of previous studies which demonstrate the subsurface connection to surface energy fluxes is strongest in such transition zones. We investigate how this connection extends into the atmosphere and can affect the structure and development of the convective boundary layer.

    The present study examined the diurnal variations of summer precipitation in the Beijing area by using subdaily precipitation and wind observations. A combined effect of topography and urbanization on the characteristics of diurnal variations was suggested. It was shown that stations located in the plain area exhibited typical night rain peaks, whereas those in the mountainous area exhibited clear afternoon peaks of precipitation diurnal variations. The precipitation peaks were associated with wind fields around the Beijing area, which were found to be highly modulated by mountain-valley circulation and urban-country circulation.The lower-tropospheric wind exhibited a clear diurnal shift in its direction from north at 0800 LST to south at 2000 LST, which reflected mountain-valley circulation. The transitions from valley to mountain wind and the opposite generally happened after sunset and sunrise, respectively, and both occurred earlier for the stations located closer to mountains. By comparing the diurnal variations of precipitation at stations in a northeast suburb, an urban area, and a southwest suburb, it was revealed that the northeast suburb group had the highest normalized rainfall frequency, but the southwest group had the lowest from late afternoon to late evening. On the contrary, in the early morning from about 0200 to 1000 LST, the southwest group and urban group had the highest normalized rainfall frequency. This pattern might originate from the combined effects of mountain-valley topography and urbanization.

    Previous studies have shown that melatonin is implicated in modulating learning and memory processing. Melatonin also exerts neuroprotective activities against Aβ-induced injury in vitro and in vivo. Neu-P11 (piromelatine, N-(2-(5-methoxy-1H-indol-3-yl)ethyl)-4-oxo-4H-pyran-2-carboxamide) is a novel melatonin (MT1/MT2) receptor agonist and a serotonin 5-HT1A/1D receptor agonist recently developed for the treatment of insomnia. In the present study we firstly investigated whether Neu-P11 and melatonin enhance memory performance in the novel object recognition (NOR) task in rats, and then assessed whether Neu-P11 and melatonin improve neuronal and cognitive impairment in a rat model of Alzheimer' disease (AD) induced by intrahippocampal Aβ(1-42) injection. The results showed that a single morning or afternoon administration of Neu-P11 enhanced object recognition memory measured at 4 or 24h after training. Melatonin was effective in the memory facilitating effects only when administered in the afternoon. Further results showed that intrahippocampal Aβ(1-42) injection resulted in hippocampal cellular loss, as well as decreased learning ability and memory in the Y maze and NOR tasks in rats. Neu-P11 but not melatonin attenuated cellular loss and cognitive impairment in the rat AD model. The current data suggest that Neu-P11 may serve as a novel agent for the treatment of AD.

    Four maize inbred lines with different photosyn-thetic rates and their two hybrids were used as test materials,and the diurnal variations of their photosynthesis parameters in the silking stage were measured to study the heterosis of photosynthetic performance.Results showed that net photo-synthetic rate (In),transpiration rate (Tr) and stomatal conductance (Gs) all presented an obvious single-peaked curve in a day,with the peak values occurring at 10:00-12:00,12:00,10:00-12:00 a.m.,respectively,while water use efficiency (WUE) had a"V"type variant trend,with the lowest value appearing at 12:00.The diurnal variation of Pn and Tr was correlated markedly with Gs,suggesting that Gs played an important role in regulating the diurnal variation of Pn and Tr,and Pn,Tr and Gs had a higher heterosis in the afternoon than in the morning,while the WUE was in reverse,indicating that maize hybrid had higher resistance to the high temperature and dehydration in the afternoon,which provided a new path to select varieties with a high net photosynthetic rate.

    Bioaerosols of university dormitory can spread through air and cause a potential health risk for student staying in indoor environment. To quantify the characteristics of bioaerosols in indoor environment of university dormitory, concentration and size distribution of culturable bioaerosols were detected during the plum rain period, the correlations of culturable bioaerosol with concentration of particulate matter, the ambient temperature and relative humidity were analyzed using Spearman's correlation coefficient and finally the changes of size distribution of culturable bioaerosol caused by activities of students were detected. The results showed that the mean concentrations of culturable airborne bacteria and fungi were (2133 +/- 1617) CFUm' and (3111 +/- 2202) CFU x m(-3). The concentrations of culturable airborne bacteria and fungi exhibited negative correlation with PM1, PM2.5, and PM10, respectively. The respirable fractions of bacteria exhibited positive correlation with PM2.5, and the respirable fractions of fungi exhibited significant positive correlation with PM10. Ambient temperature had positive correlation with culturable airborne bacteria and fungi, and relative humidity had negative correlation with culturable airborne bacteria and fungi. In the afternoon, concentrations of culturable airborne fungi in indoor environment of university dormitory significantly increased, and the size distribution of culturable hioaerosols was different in the morning and afternoon.

    Full Text Available Many studies report adverse environmental conditions, damage yield, especially in dairy cows. However, studies on the effects of environment on young animals, especially calves of mixed race, are rare. Study effects of time, day and type of shading on the physiological responses of crossbred calves in tropical environment. Twenty-four ½ Holstein and SPRD (without defined breed calves were identified in two nursery facilities, one provided with natural shading and the other provided with artificial shading by means of cement tile. In both facilities, environmental data including air temperature, wind speed, and black globe temperature were recorded between7 a.m. to 4 p.m. to calculate the radiant thermal load. Physiological responses, rectal temperature and respiratory rates were measured in the morning and in the afternoon. The natural shading provided less thermal comfort because of higher radiant thermal load, especially in the afternoon. The crossbred calves showed higher rectal temperature and respiratory frequency as compared with SPRD calves in both periods and in both nursery facilities, with the highest values reported under natural shading. Calves of different genotypes respond differently in hot environments, should be to test in future research another types of trees to verify their thermal quality.

  13. Lattice Wind Description and Characterization of Mexico City Local Wind Events in the 2001–2006 Period

    Directory of Open Access Journals (Sweden)

    2015-07-01

    Full Text Available Urban transformation and expansion in Mexico City continuously affect its urban morphology, and therefore the modes of wind circulation inside it and their occurrence probabilities. Knowledge on these topics is an important issue for urban planning and for other urban studies, such as air quality assessment. In this paper, using a lattice wind model at a meso-β scale, we develop a simple description and characterization of Mexico City local wind events that occurred during the period 2001–2006, including an estimation of the occurrence probabilities. This region was modeled as a 2D lattice domain of identical cells, and wind conditions in each cell were described by four wind attributes: the horizontal velocity components, divergence, and vorticity. Models of one and four cells were applied to wind data furnished by the meteorological network of the city. Results include the following: Early morning: low intensity winds (75% from N, NW, W and SW (75%, convergent (93%, with a slight predominance of cyclonic vorticity (54%. Morning and early afternoon: winds from N, NE and E (72% with speeds from 0.5 to 3.5 m/s, slight prevailing of convergent winds (51%, and slight predominance of cyclonic vorticity (57%. Late afternoon and night: winds blowing from N, NW, and S (63% with speeds from 1.5 to 3.5 m/s (66%, convergent (90%, and cyclonic (72%.

  14. Ammonia volatilization from nitrogen fertilizers in no-till wheat and maize in southern Brazil

    Full Text Available Crop residues on the soil surface of no-till systems can intensify ammonia volatilization from N fertilizers applied to cereal crops. This study assessed the magnitude of N losses through ammonia volatilization from urea applied to no-till winter (wheat and summer crops (maize on a Typic Hapludox in the south-central region of Paraná, southern Brazil. In addition, the potential of alternative N sources (urea with urease inhibitor, liquid fertilizer, ammonium nitrate and ammonium sulfate and different urea managements (fertilizer applied in the morning or afternoon were evaluated. Two experiments with maize and wheat were carried out for two years, arranged in a randomized block design with four replications. Nitrogen volatilization losses were assessed with a semi-open static collector until 21 days after fertilization. In winter, the losses were low (<5.5 % of applied N for all N sources, which were not distinguishable, due to the low temperatures. In the summer, volatilization rates from urea were higher than in the winter, but did not exceed 15 % of applied N. The main factor decreasing N losses in the summer was the occurrence of rainfall in the first five days after fertilization. Urea with urease inhibitor, nitrate and ammonium sulfate were efficient to decrease ammonia volatilization in maize, whereas the application time (morning or afternoon had no influence.

  15. Experimental study of turbulence induced wall temperature fluctuations

    Turbulent heat transport is critical in engineering applications and atmospheric flows. The relative strength of background shear and buoyancy near the wall influences coherent structures responsible for much of the heat transport. Previous studies show that shear dominated flow causes streaky-like structures; whereas buoyancy dominated flow causes cell-like structures. In this work, we investigated the influence of flow structures on the wall temperature and heat flux in a convective atmospheric boundary layer. Turbulence data at different heights and high frequency wall temperature were obtained during the Boundary Layer Late Afternoon and Sunset Turbulence field campaign at Lannemezan, France from 7 June - 8 July, 2011. Conditional averaging confirms that the warm wall causes warm ejection events, and cold sweep events cause cooling of the wall. The wall temperature structures move along the wind and their advection speed is close to the wind speed of the upper logarithmic layer and mixed layer, have a size of about 0.2 times the boundary layer depth, become streakier with stability and its standard deviation follows a -1/3 power law with stability parameter, Obukhov length. We are thankful to all Boundary Layer Late Afternoon and Sunset Turbulence field campaign participants for data sharing and funding from a NASA New Investigator Program award.

    Two teachers and a parent used three basic multiple baseline designs to investigate the effects of systematic reinforcement and punishment procedures in the classroom and at home. (1) A fifth-grade teacher concurrently measured the same behavior (tardiness) in three stimulus situations (after morning, noon, and afternoon recesses). Posting the names of pupils on a chart titled "Today's Patriots" was made contingent on being on time after the noon recess, then successively also the morning and afternoon recesses. Tardiness was reduced to near zero rates at the points where contingencies were applied. (2) A highschool teacher recorded the same behavior (daily French-quiz grades) of three students. She then successively applied the same consequences (staying after school for individual tutoring for D and F grades) for each student. At the points where the contingency was applied, D and F grades were eliminated. (3) A mother concurrently measured three different behaviors (clarinet practice, Campfire project work, reading) of her 10-yr-old daughter. She successively applied the same contingency (going to bed early) for less than 30 min spent engaged in one after another of the behaviors. Marked increases in the behaviors were observed at the points where the contingency was applied.

    We present field observations made in June 2011 downwind of Dallas-Fort Worth, TX, and evaluate the role of stabilized Criegee radicals (sCIs) in gaseous sulfuric acid (H2SO4) production. Zero-dimensional model calculations show that sCI from BVOCs composed the majority of the sCIs. The main uncertainty associated with an evaluation of H2SO4 production from the sCI reaction channel is the lack of experimentally determined reaction rates for sCIs formed from isoprene ozonolysis with SO2. In general, the maximum of H2SO4 production from the sCI channel is found in the late afternoon as ozone increases towards the late afternoon. The sCI channel, however, contributes minor H2SO4 production compared with the conventional OH channel. Finally, The production and the loss rates of H2SO4 are compared. The application of the recommended mass accommodation coefficient causes significant overestimation of H2SO4 loss rates compared with H2SO4 production rates. On the other hand, the application of a lower experimental value for the mass accommodation coefficient provides good agreement between the loss and production rates of H2SO4. The results suggest that the recommended coefficient for the H2O surface may not be suitable for this relatively dry environment.

    Full Text Available Study on daytime descending intermediate layer over subtropical Indian station Waltair (17.7° N, 83.3° E geographic, 6.4° N, 10° E geomagnetic, 20° N dip located in the equatorial anomaly transition region, using an IPS 42 Digital Ionosonde during the low solar activity year 2004 showed that the layers occur in the altitude range of 140–160 km with maximum occurrence during winter solstice. The layers observed during daytime occur with a double peak variation throughout the year with less occurrence probability and shorter duration presence during forenoon hours. The morning layer descent was associated with a density increase where as during afternoon hours a decrease in density was observed. The downward drift velocity was about 8 km/h during morning hours and between 7–11 km/h during afternoon hours, with a low descent rate of around 4.5 km/h during summer morning hours. The results indicate the presence of a 6 h tide at this location as observed from the characteristics of the descending layers, unlike at majority of locations where a significant semi diurnal trend is observed. The study brings out the complex nature of the tidal interaction at different locations.

    Full Text Available The purpose of this research was to investigate rates of residual-limb fluid volume change within one day for people with transtibial limb loss. Rates of fluid volume change during 30 min test sessions of sitting, standing, and walking activities were measured twice a day, once in the morning and once in the afternoon, on 12 regular prosthesis users with the use of bioimpedance analysis. Between test sessions, all subjects consumed food and drink, and subject activity ranged from low to high. The rate of fluid volume change within sessions ranged from −8.5 to 5.9 %/h (median: −2.2 %/h. The rate of fluid volume change between sessions ranged from −2.7 to 0.9 %/h (median: −1.0 %/h. The between-session rate of fluid volume change correlated highly with afternoon within-session rates of change (r = 0.9 but was not well correlated with morning within-session rates of change (r = 0.8. Subjects with peripheral arterial complications showed greater fluid volume loss rates during test sessions than between sessions. Rate of fluid volume change may be affected by sitting, standing, and walking activities; presence of peripheral arterial complications; being female; time since amputation; and wearing the socket without doffing for extended periods.
