Developing technological issues provided that measure complex structure of team sports physiological loading during competition and trainings. During the last decade, limited numbers of researches reported about loading intensity and physiological response of junior girl basketball players during official competition. In this context, The aim of this study is determine of heart rate (HR) response during official competition in junior girl basketball players. 12 junior girl basketball players (age: 14.75±0.55 years, height: 168.48±5.3 cm, weight: 62.6±9.52 kg, predicted VO²max: 49.76±3.64 ml/kg/min) participated to this study. The HR measurements were taken official regional clubs league championship. Two days after followed up competition players performed the Shuttle Run Test (SRT) for determine maxHR levels. All HR measurement was taken by Polar Team2 (Finland). Frequency analyses were performed for the obtained data. Wilcoxon Rank Test was used for determined HR difference between halves. Friedman’s test was used for detected HR differences between periods. According to the analysis results, the maxHR levels obtained during SRT of the players were determined as 196,33 ± 10,04. The meanHR was determined 176,03±10,36 (89.66% of maxHR) in all competition. First half meanHR was 177,16±13,19 (90.23% of maxHR), second half meanHR was 175,00±11,56 (89.13% of maxHR), first period meanHR was 177,16±13,94 (90.00% of maxHR), second period meanHR was 176,87±12,10 (88.88% of maxHR), third period meanHR was 176,88±12,10 (90.08% of maxHR), fourth period meanHR was 179,40±10,71 (91.73% of maxHR).  There were no difference found between halves and periods (p>0.05). As a result of this study, HR response showed that intensity of junior girl basketball competition is approximately 89,66% of maxHR. This results showed that competition intensity is very high during all halves and periods. The determination of the official competition intensity of junior girl basketball players can provide important knowledge to coaches that young players have improved their sporting performance.  ÖzetMüsabaka ve antrenmanlar sırasında takım sporunun fizyolojik yükünün karmaşık yapısını ölçen teknolojik gelişmeler sağlanmıştır. Son on yılda, resmi müsabaka sırasında yıldız kız basketbolcuların fizyolojik tepkileri ve yüklenme yoğunluğu ile ilgili sınırlı sayıda araştırma rapor edilmiştir. Bu bağlamda, bu çalışmanın amacı, yıldız kız basketbolcuların resmi müsabaka sırasında kalp atım hızı (KAH) yanıtlarını belirlemektir. Çalışmaya 12 yıldız kız basketbolcu (yaş: 14,75±0,55, boy: 168,48±5,30, vücut ağırlığı: 62,6±9,52, tahmini VO²maks: 49,76±3,64 ml/kg/dk) katıldı. KAH ölçümleri resmi bölgesel klüpler lig şampiyonasında alındı. Maçtan iki gün sonra KAH seviyelerini belirlemek için 20 m. Mekik Koşusu Testi (20MKT) uygulandı. Basketbolcuların müsabaka ve 20MKT sırasında kalp atım hızları Polar Team2 (Finland) sistem ile ölçüldü. Elde edilen veriler için frekans analizi uygulandı. Yarılar arasındaki KAH farkı için Wilcoxon Rank Testi kullanıldı. Periodlar arasındaki KAH farkları Friedman’s Testi ile tespit edildi. Analiz sonuçlarına göre, oyuncuların 20MKT sırasında elde edilen maksKAH değerleri 196,33±10.04 olarak tespit edildi. Basketbolcuların tüm müsabaka ortKAH 175,93±10,19 (maks KAH’ın %89.66). İlk yarı ortKAH 177,16±13,19 (maksKAH'ın %90.23), ikinci yarı ortHR 175,00±11,56 (maksKAH'ın 89.13), ilk period ortHR 177,16±13,94 (maksKAH'ın %90.00), ikinci period ortHR 176,87 ± 12,10 (maksKAH'ın %88.88), üçüncü period ortHR 176,88±12,10 (maksKAH'ın %90.08), dördüncü period ortHR 179,40±10,71 (maksKAH'ın %91.73) olarak tespit edildi. Periyotlar ve yarılar arasında ortKAH bakımından anlamlı fark bulunmamıştır (p>0.05). Bu çalışmanın bir sonucu olarak, yıldız kız basketbol müsabakasında KAH cevaplarının maxKAH'ın yaklaşık %89,66 şiddetinde olduğu görüldü. Bu sonuçlar, müsabaka yoğunluğunun tüm yarılar ve periyotlar için çok yüksek olduğunu göstermektedir. Yıldız oyuncuların resmi müsabaka yoğunluğunun belirlenmesi, genç oyuncuların spor performansını geliştirdiklerine dair antrenörlere önemli bilgi sağlayabilir.

AbstractThis study was conducted to correlate and compare values for variables determined in indirect tests with the values determined directly in youth soccer players. The study subjects were 27 youth soccer players (age 16.77 ± 0.75 years; body mass 63.29 ± 7.37 kg; body height 174.14 ± 8.46 cm) playing in the basic categories of a first division team at the regional level of Brazilian soccer. Each subject was evaluated with the following tests: a) a treadmill test to directly determine values of VO2max and Vamax (Treadmill); b) an indirect Shuttle Run Test (SRT); c) an indirect Carminatti’s test (TCar). VO2max showed significantly different values in the Treadmill and the SRT (59.21 ± 5.88 and 50.67 ± 3.58 ml⋅kg−1⋅min−1, respectively). Similarly, values obtained for VPeak in the treadmill test and for Vamax in TCar were different from values for SRT VPeak (15.01 ± 1.10, 14.92 ± 0.87 and 12.64 ± 0.62 km⋅h−1, respectively). A correlation analysis showed a moderate relationship between values for VPeak TCar and VO2max determined on a treadmill (r = 0.46) and Vamax determined on a treadmill (r = 0.54). The analysis also showed a high correlation between values of VO2max determined on the treadmill and VO2max evaluated in the SRT (r = 0.69), as well as VPeak determined in the SRT and VO2max tested on the treadmill (r = 0.71), as well as between VPeak determined in the SRT and VO2max evaluated on the treadmill (r = 0.77). We concluded that the SRT underestimated values of VO2max and Vamax. Additionally, VPeak TCar showed no difference compared to Vamax, although it did show a low correlation with it. In addition the SRT, even with high correlations, did not seem to be a great predictor of aerobic fitness in youth soccer players.

The Galaxy

It is now possible to determine proper motions of high-velocity objects in such a way as to obtain with some accuracy the velocity vector relevant to the Sun. If a potential field of the Galaxy is assumed, one can compute an actual orbit. A determination of the velocity of the globular clusterωCentauri has recently been completed at Greenwich, and it is found that the orbit is strongly retrograde in the Galaxy. Similar calculations may be made, though with less certainty, in the case of RR Lyrae variable stars.

Sn 1987A

Using the new reductions of the IUE light curves by Sonneborn et al. (1997) and an extensive set of HST images of SN 1987A we have repeated and improved Panagia et al. (1991) analysis to obtain a better determination of the distance to the supernova. In this way we have derived an absolute size of the ringRabs= (6.23 ± 0.08) x 1017cm and an angular sizeR″ = 808 ± 17 mas, which give a distance to the supernovad(SN1987A) = 51.4 ± 1.2 kpc and a distance modulusm–M(SN1987A) = 18.55 ± 0.05. Allowing for a displacement of SN 1987A position relative to the LMC center, the distance to the barycenter of the Large Magellanic Cloud is also estimated to bed(LMC) = 52.0±1.3 kpc, which corresponds to a distance modulus ofm–M(LMC) = 18.58±0.05.

In South Africa the modern outlook towards time may be said to have started in 1948. Both the two major observatories, The Royal Observatory in Cape Town and the Union Observatory (now known as the Republic Observatory) in Johannesburg had, of course, been involved in the astronomical determination of time almost from their inception, and the Johannesburg Observatory has been responsible for the official time of South Africa since 1908. However the pendulum clocks then in use could not be relied on to provide an accuracy better than about 1/10 second, which was of the same order as that of the astronomical observations. It is doubtful if much use was made of even this limited accuracy outside the two observatories, and although there may – occasionally have been a demand for more accurate time, it was certainly not voiced.

AbstractPrecise measurements of heliographic position of solar filaments were used for determination of the proper motion of solar filaments on the time-scale of days. The filaments have a tendency to make a shaking or waving of the external structure and to make a general movement of whole filament body, coinciding with the transport of the magnetic flux in the photosphere. The velocity scatter of individual measured points is about one order higher than the accuracy of measurements.

AbstractObservations of artificial earth satellites provide a means of establishing an.origin, orientation, scale and control points for a coordinate system. Neither existing data nor future data are likely to provide significant information on the .001 angle between the axis of angular momentum and axis of rotation. Existing data have provided data to about .01 accuracy on the pole position and to possibly a meter on the origin of the system and for control points. The longitude origin is essentially arbitrary. While these accuracies permit acquisition of useful data on tides and polar motion through dynamio analyses, they are inadequate for determination of crustal motion or significant improvement in polar motion. The limitations arise from gravity, drag and radiation forces on the satellites as well as from instrument errors. Improvements in laser equipment and the launch of the dense LAGEOS satellite in an orbit high enough to suppress significant gravity and drag errors will permit determination of crustal motion and more accurate, higher frequency, polar motion. However, the reference frame for the results is likely to be an average reference frame defined by the observing stations, resulting in significant corrections to be determined for effects of changes in station configuration and data losses.
