Response of the ATLAS tile calorimeter prototype to muons

A study of high energy muons traversing the ATLAS hadron Tile calorimeter in the barrel region in the energy range between 10 and 300~GeV is presented. Both test beam experimental data and Monte Carlo simulations are given and show good agreement. The Tile calorimeter capability of detecting isolated muons over the above energy range is demonstrated. A signal to background ratio of about 10 is expected for the nominal LHC luminosity ($10^{34} cm^{-2} sec^{-1}$). The photoelectron statistics effect in the muon shape response is shown. The e/mip ratio is found to be $0.81 \pm 0.03$; the e/$\mu$ ratio is in the range 0.91 - 0.97. The energy loss of a muon in the calorimeter, dominated by the energy lost in the absorber, can be correlated to the energy loss in the active material. This correlation allows one to correct on an event by event basis the muon energy loss in the calorimeter and therefore reduce the low energy tails in the muon momentum distribution

Evaluation of Fermi Read-out of the ATLAS Tilecal Prototype

Prototypes of the \fermi{} system have been used to read out a prototype of the \atlas{} hadron calorimeter in a beam test at the CERN SPS. The \fermi{} read-out system, using a compressor and a 40 MHz sampling ADC, is compared to a standard charge integrating read-out by measuring the energy resolution of the calorimeter separately with the two systems on the same events. Signal processing techniques have been designed to optimize the treatment of \fermi{} data. The resulting energy resolution is better than the one obtained with the standard read-out

A measurement of the energy loss spectrum of 150 GeV muons in iron

The energy loss spectrum of 150 GeV muons has been measured with a prototype of the ATLAS hadron calorimeter in the H8 beam of the CERN SPS.\\ The differential probability $dP/dv$ per radiation length of a fractional energy loss $v = \Delta E_{\mu} / E_{\mu}$ has been measured in the range $v = 0.01 \div 0.95$; it is then compared with the theoretical predictions for energy losses due to bremsstrahlung and production of electron-positron pairs or of energetic knock-on electrons.\\ The integrated probability $\int_{0.01}^{0.95} (dP/dv) dv$ is $(1.610\pm0.015_{stat.}\pm0.105_{syst.})\cdot10^{-3}$ in agreement with the theoretical predictions of $1.556\cdot10^{-3}$ and $1.619\cdot10^{-3}$. %7.8.96 - start Agreement with theory is also found in two intervals of $v$ where production of electron-positron pairs and knock-on electrons dominates. In the region of bremsstrahlung dominance ($v = 0.12\div0.95$) the measured integrated probability $(1.160\pm0.040_{stat}\pm0.075_{syst})\cdot 10^{-4}$ is in agreement with the theoretical value of $1.185 \cdot 10^{-4}$, obtained using Petrukhin and Shestakov's \cite{PS} description of the bremsstrahlung process. The same result is about 3.6 standard deviations (defined as the quadratic sum of statistical and systematic errors) lower than the theoretical prediction of $1.472\cdot 10^{-4}$, obtained using Tsai's \cite{TS} description of bremsstrahlung

Results from a combined test of an electromagnetic liquid argon calorimeter with a hadronic scintillating-tile calorimeter

The first combined test of an electromagnetic liquid argon accordion calorimeter and a hadronic scintillating-tile calorimeter was carried out at the CERN SPS. These devices are prototypes of the barrel calorimeter of the future ATLAS experiment at the LHC. The energy resolution of pions in the energy range from 20 to 300~GeV at an incident angle $\theta$ of about 11$^\circ$ is well-described by the expression \sigma/E = ((46.5 \pm 6.0)\%/\sqrt{E} +(1.2 \pm 0.3)\%) \oplus (3.2 \pm 0.4)~\mbox{GeV}/E. Shower profiles, shower leakage, and the angular resolution of hadronic showers were also studied

The Effectiveness of Multilevel Promotion ofExclusive Breastfeeding in Rural Indonesia

Purpose. To examine the effectiveness of multilevel promotion on exclusive breastfeeding (EBF)duration and prevalence.Design. A pretest-posttest control group design, quasi-experiment.Setting. Two public health centers in the Demak District, Central Java, Indonesia.Subjects. A total of 163 families were enrolled, including pregnant mothers, fathers, andgrandmothers.Intervention. The multilevel promotion of EBF was conducted at the subdistrict, village, family, andindividual levels. This was a complex intervention that modified breastfeeding determinants, integratedmultidisciplinary partnerships, and involved community leaders (i.e., voluntary health workers,traditional birth attendants, Muslim scholars, and heads of villages). The strategies applied wereadvocacy, training, media, and home visit counseling.Measures. EBF duration and prevalence.Analysis. Survival analyses, Cox proportional-hazard model.Results. The duration of EBF increased after the multilevel promotion. The median postinterventionduration in the intervention group was 18 weeks compared with .1 week in the control group (p , .001).The prevalence of EBF at 1, 8, 16, and 24 weeks for the intervention versus control groups was 75.3% vs.28.0%, 64.2% vs. 14.6%, 50.6% vs. 8.5%, and 37.0% vs. 3.7%, respectively (p , .001). Mothersin the control group were three times more likely to stop exclusive breastfeeding per unit of time than weremothers in the intervention group (adjusted hazard ratio 3.01; 95% confidence interval: 1.96, 4.63).Conclusion. Multilevel promotion ca

PROMOSI WISATA SEBAGAI UPAYA PENGOPTIMALAN POTENSI WISATA DI DESA SANGGU KABUPATEN BARITO SELATAN

Potensi wisata adalah segala sesuatu yang dimiliki oleh daerah tujuan wisata, dan merupakan daya tarik agar orang-orang mau datang berkunjung ke tempat tersebut . Desa memiliki banyak sekali potensi yang masih belum dimanfaatkan atau belum diolah secara baik, terutama pada sektor wisata. Setiap desa memiliki potensi yang kadang masyarakat sekitarnya sendiri pun belum melihat potensi tersebut. Dengan adanya kegiatan KKN-T Mandiri di Desa Sanggu, Mahasiswa(i) KKN berusaha membantu mengoptimalkan potensi wisata Desa Sanggu dengan mempromosikan wisata. Desa Sanggu merupakan salah satu desa yang terletak di Kecamatan Dusun Selatan, Kabupaten Barito Selatan. Meskipun Desa Sanggu dikenal sebagai desa wisata yang ada di Kabupaten Barito Selatan, namun tingkat pengembangan dan promosi wisata masih kurang maksimal. Adapun tujuan dilakukan promosi potensi wisata desa adalah untuk mengenalkan wisata desa ke publik secara luas. Metode pelaksanaan program kerja ini dilakukan dengan pembutan video, brosur, dan media sosial. Kegiatan program kerja ini berjanlan dengan lancar dan mendapat antusias masyarakat Desa Sangg
