A large scale height galactic component of the diffuse 2-60 keV background

The diffuse 2-60 keV X-ray background has a galactic component clearly detectable by its strong variation with both galactic latitude and longitude. This galactic component is typically 10 percent of the extragalactic background toward the galactic center, half that strong toward the anticenter, and extrapolated to a few percent of the extragalactic background toward the galactic poles. It is acceptably modeled by a finite radius emission disk with a scale height of several kiloparsecs. The averaged galactic spectrum is best fitted by a thermal spectrum of kT about 9 keV, a spectrum much softer than the about 40 keV spectrum of the extragalactic component. The most likely source of this emission is low luminosity stars with large scale heights such as subdwarfs. Inverse Compton emission from GeV electrons on the microwave background contributes only a fraction of the galactic component unless the local cosmic ray electron spectrum and intensity are atypical

Microgravity and its effects on residual motions in fluids

The primary reason for conducting many materials science experiments in space is to minimize or eliminate undesirable effects that might result owing to convective motions in fluids that are driven by buoyancy effects. Of particular concern are the low frequency accelerations caused by the Earth's gravity gradient field, spacecraft attitude motions, and atmospheric drag. In order to gain a limited understanding of the effects of these accelerations, researchers calculated the Stokes' motion of a spherical particle in a fluid for various types of spacecraft attitudes. Researchers assessed the effect of slowly rotating the experimental system relative to the spacecraft in order to reduce the rate at which the particles accumulate against the container wall

Hubungan Penilaian Status Gizi Dengan Metode BMI (Body Mass Index) Dan Metode LLA (Lingkar Lengan Atas) Pada Anak Perempuan Usia 6-10 Tahun

Overweight / obesity and under-nutrition in children can cause problems; therefore, it is important for us to correctly acknowledge nutritional value in children’s early age. To determine nutritional status, WHO-NCHS  recommends  Body  Mass  Index  (BMI);  however,  it  is  difficult  to  be  used  routinely.  The measurement of mid-upper arm circumference is an easier way to assess children’s nutritional value. This study tries to find out the relation between BMI and upper arm’s circumference in predicting nutritional status  of  children  aged  6-10.  The  research  design  is  analytical  observational,  whereas  the  data  were collected  from  163  students  of  the  Penabur  Christian  Elementary  School  6,  in  February  2009.The research subjects were 6 – 10 years old, 113 – 147 cm tall , 21.3 – 53 kg in weight, and had 14.96 – 31.19 kg/m2 of BMI, and 16.5 – 31.2 cm of mid-upper arm circumference. The result showed that children with BMI y  =  19.1  (SD  =  2.80),  had  LLA  x  =  22.0  (SD  =  2.88).  The  form  of  relation  in  simple  linear regression equation is BMI = -0.703 + 0.898 LLA ** (p = 0.000). The strength of relation between BMI and LLA is highly significant with r = 0.926 ** (p = 0.000). Children’s cut off point of mid-upper arm circumference  is  21.75  cm.  In  conclusion,  BMI  has  a  strong  correlation  to  upper  arm  circumference  in predicting nutritional status of girls aged 6-10 years old. &nbsp

Strategi WOW (Wide Open Wonder) untuk Meningkatkan Keaktifan dan Prestasi Matematika Siswa (Penelitian Tindakan Kelas pada Siswa Kelas VII C SMPN 4 Geyer Grobogan pada 2014/2015)

Penelitian ini dilatarbelakangi oleh masih rendahnya partisipasi keaktifan dan prestasi siswa kelas VII C SMP Negeri 4 Geyer Grobogan Jawa Tengah dalam pembelajaran matematika. Hal tersebut berdasarkan studi awal yang menemukan bahwa siswa yang aktif baru 23,57% dari keseluruhan siswa dan rata-rata prestasi matematika hanya 66,07. Dengan menerapkan penelitian tindakan kelas dan dengan menggunakan strategi Wide Open Wonder (WOW) berhasil meningkatkan keaktifan dan prestasi matematika siswa. Penelitian ini dilaksanakan pada tahun pelajaran 2014/2015 terhadap 28 siswa kelas VII C SMP Negeri 4 Geyer Grobogan Jawa Tengah yang terlaksana sebanyak 2 siklus. Adapun teknik pengumpulan data dilakukan dengan observasi dan tes. Keberhasilan penelitian ini yaitu dapat meningkatkan keaktifan siswa hingga mencapai 58,57% dan meningkatkan rata-rata nilai prestasi matematika mencapai 75,36 serta sebanyak 85,71% siswa telah berhasil melampaui kriteria ketuntasan minimal (KKM)

Comment on `Series expansions from the corner transfer matrix renormalization group method: the hard-squares model'

Earlier this year Chan extended the low-density series for the hard-squares partition function $\kappa(z)$ to 92 terms. Here we analyse this extended series focusing on the behaviour at the dominant singularity $z_d$ which lies on on the negative fugacity axis. We find that the series has a confluent singularity of order 2 at $z_d$ with exponents $\theta=0.83333(2)$ and $\theta'= 1.6676(3)$. We thus confirm that the exponent $\theta$ has the exact value $\frac56$ as observed by Dhar.Comment: 5 pages, 1 figure, IoP macros. Expanded second and final versio

Pengaruh Lingkungan Kerja dan Budaya Organisasi terhadap Kinerja Karyawan PT. Bank Riau Kepri Capem Duri

This study was conducted to determine the effect of work environment and organizational culture and work simultaneosly on employee performance PT. Bank Riau Kepri Capem Duri Riau, and to determine and analyze the effect of work environment and organizational culture on employee performance partially.Variable in this study is thr work environment, organization culture and performance and while the population is all employees in PT. Bank Riau Kepri Capem Duri amounted to 35 people. The sampling method the author uses census, all the population be the sample. In this study the data obtained will be processed by multiple linear regression models. Regression methods can be used to show how the independent variables affect the dependent variable.The first hypothesis test result indicate that the work environment affect the performance of the employees at PT.

The Constitutional Court\u27s Role in Consolidating Democracy and Reforming Local Election

Within the same group as the USA and India Indonesia is one of the largest democracies in the world. After experiencing authoritarian rule for a few decades since its independence the country finally at the beginning of the twenty first century managed to chart along its new direction along democratic course and values. More than a decade has passed since the democratic transition begun yet the country still faces various constitutional dilemmas and enigmas. One of organs of the government which has been entrusted to transform the country into a democratic nation is the Constitutional Court. The objective of this paper is to provide critical analyses of the role of the Constitutional Court of Indonesia in the process of consolidating local democracy. The scope of analysis is confined to a number of important cases heard by the court on local election disputes from the year 2008 to 2013. The rationale to focus on local election is because local government provides the second layer of government for this unitary country making the governance more democratic and more in touch with local population. The result of the study is the Constitutional Court through its decisions has created conducive political situation and has provided significant contributions in the process of consolidating local democracy. In spite of limited number of judges and short period of settlement to disputes brought before it the Court have settled all disputes regarding local elections without much delay and complaint. Nevertheless there are some areas that need to be addressed by the court to enhance its efficiency and effectiveness. A few factors have been identified to be the cause of the problems namely problem of design of structure of the Court, extension of the scope of authority, period of settlement, over-dosis of authority and the breach of code of ethics of the judges.Thus it is recommended that in order to perpetuate the excellent achievements of the court the institution need to be strengthened by addressing the problems
