Sticky physics of joy: On the dissolution of spherical candies
Assuming a constant mass-decrease per unit-surface and -time we provide a
very simplistic model for the dissolution process of spherical candies. The aim
is to investigate the quantitative behavior of the dissolution process
throughout the act of eating the candy. In our model we do not take any
microscopic mechanism of the dissolution process into account, but rather
provide an estimate which is based on easy-to-follow calculations. Having
obtained a description based on this calculation, we confirm the assumed
behavior by providing experimental data of the dissolution process. Besides a
deviation from our prediction caused by the production process of the candies
below a diameter of 2 mm, we find good agreement with our model-based
expectations. Serious questions on the optimal strategy of enjoying a candy
will be addressed, like whether it is wise to split the candy by breaking it
with the teeth or not
Using Feedback In Teaching Writing Descriptive Text
This study is to see the improvement of student's writing skill on descriptive text for seventh grade students of SMP 14 Kota Serang by using peer feedback technique. The subject of this research is the students of seventh grade of SMP 14 Kota Serang which consist of 30 students. This research is applied by a quasi-experimental design and quantitative research method. The instrument used in this research was tests (pre-test and post-test) which is conducted based on the main problems: 1) How is the students writing ability on descriptive text at the seventh grade of SMP 14 Kota serang? 2) How is the effectiveness of peer feedback in teaching writing descriptive text at the seventh grade of SMP 14 Kota serang?. The research finding of the last result showed that “to” from the calculation is higher than t table both at significance level 5% and 1%. Significance 5% t observation= 7.14 and t table= 1.67 or 7.14 >1.67 which its significance 1% t observation=7.14 and t table= 2.39 or 7.14 >2.39. In addition, the result of observations showed that the students more motivated in learning English, especially for writing subject. Based on the result above, it can be concluded that peer feedback can be used in teaching writing descriptive text. The result of this research shows that the students' writing on descriptive text who use peer feedback achieve better performance than those who do not use it.

The Impact of Community Based Adventure Therapy on Stress and Coping Skills in Adults.
Stress and coping skills are among the most essential components of the mental health counseling field. The use of coping skills (e.g., meditation, physical activities, appropriate uses of leisure) has been identified as an effective strategy for stress management. Adventure therapy has emerged as a modality that can positively augment other therapeutic approaches by improving coping skills and assisting clients in managing stress. As with all therapies, a positive working alliance has been found to be important toward achieving clinical outcomes. This study explored how adventure therapy enhanced learned coping strategies for stress and improved therapeutic alliance. Outcomes from this exploratory research highlighted the potential of adventure therapy to decrease stress, increase coping skills, and build therapeutic rapport with the therapist
Smoothing of sandpile surfaces after intermittent and continuous avalanches: three models in search of an experiment
We present and analyse in this paper three models of coupled continuum
equations all united by a common theme: the intuitive notion that sandpile
surfaces are left smoother by the propagation of avalanches across them. Two of
these concern smoothing at the `bare' interface, appropriate to intermittent
avalanche flow, while one of them models smoothing at the effective surface
defined by a cloud of flowing grains across the `bare' interface, which is
appropriate to the regime where avalanches flow continuously across the
sandpile.Comment: 17 pages and 26 figures. Submitted to Physical Review
The Spatial Distribution Of OH And CN Radicals In The Coma Of Comet Encke
Multiple potential parent species have been proposed to explain CN abundances in comet comae, but the parent has not been definitively identified for all comets. This study examines the spatial distribution of CN radicals in the coma of comet Encke and determines the likelihood that CN is a photodissociative daughter of HCN in the coma. Comet Encke is the shortest orbital period (3.3 years) comet known and also has a low dust-to-gas ratio based on optical observations. Observations of CN were obtained from 2003 October 22 to 24, using the 2.7 m telescope at McDonald Observatory. To determine the parent of CN, the classical vectorial model was modified by using a cone shape in order to reproduce Encke's highly aspherical and asymmetric coma. To test the robustness of the modified model, the spatial distribution of OH was also modeled. This also allowed us to obtain CN/OH ratios in the coma. Overall, we find the CN/OH ratio to be 0.009 +/- 0.004. The results are consistent with HCN being the photodissociative parent of CN, but we cannot completely rule out other possible parents such as CH(3)CN and HC(3)N. We also found that the fan-like feature spans similar to 90 degrees, consistent with the results of Woodney et al..NASAOffice of the Vice President for Research and Economic Development at Mississippi State UniversityMcDonald Observator
Pengaruh Pergerakan terhadap Pola Konsumsi Tenaga Kerja di Kawasan Industri Wijayakusuma
Kawasan industri menyerap banyak tenaga kerja dari berbagai wilayah baik dari dalam kota maupun dari luar kota. Salah satunya Kawasan Industri Wijayakusuma yang terletak di jalan raya ekonomi Semarang-Jakarta.Banyak tenaga kerja industri yang melakukan pergerakan dari tempat tinggalnya menuju ke tempat bekerjanya yaitu Kawasan Industri Wijayakusuma maupun sebaliknya setiap hari. Perlunya mengetahui karakteristik sosial-demografi dan ekonomi, karakteristik pergerakan, dan karakteristik pola konsumsi tenaga kerja agar dapat mengetahui pengaruhnya satu sama lain.Dalam penelitian ini ternyata di temukan bahwa pergerakan akan mempengaruhi pola konsumsi tenaga kerja. Terlihat dari jenis kelamin akan mempengaruhi jarak tempuh, waktu tempuh, dan kendaraan yang akan di gunakan ke tempat bekerja. Perempuan lebih cenderung memiliki jarak tempuh dan waktu tempuh yang lebih pendek daripada laki-laki.Pendapatan juga akan mempengaruhi kendaraan yang akan di gunakan oleh tenaga kerja, serta jumlah kendaraan yang di miliki akan mempengaruhi juga pada kendaraan yang akan di gunakan dan frekuensi perjalanan si tenaga kerja eitu sendiri Jarak tempuh dan waktu tempuh tenaga kerja ternyata akan mempngaruhi pola konsumsinya khususnya pada proporsi pola untuk transportasi, semakin jauh jarak tempuh atau semakin lama waktu tempuh tenaga kerja akan semakin besar proporsi pola untuk transportasinya. Jika jarak tempuhnya semakin jauh juga maka akan ada perilaku tenaga kerja untuk menekan proporsi pola non pangannya agar semua kebutuhannya akan tercukupi.Namun,bagaimanapun pergerakan tenaga kerja tidak akan mempengaruhi proporsi pola untuk pangannya karena hal ini merupakan kebutuhan primer yang tidak dapat di ganti dengan kebutuhan lainnya.Penyediaan sarana transportasi yang memadai, melihat juga dari aspk biaya karena hal ini akan menjadi faktor pertimbangan untuk tenaga kerja dalam memilih kendaraan yang akan di gunakan ke tempat kerja.Selain itu, perlunya penyediaan Perumahan di sekitar kawasan industri, agar jarak tempuh dan waktu tempuh tenaga kerja akan semakin dekat sehingga, akan semakin efektif dan efisien baik dalam waktu, tenaga, dan biaya yang akan di keluarkan untuk transportasi
