    The Tsallis Distribution at Large Transverse Momenta

    Fits to the transverse momentum distributions of charged particles produced in p - p collisions at LHC energies based on the Tsallis distribution have been shown to work over 14 orders of magnitude. Two versions of the Tsallis distribution are compared and discussed, the thermodynamically consistent version leads to a temperature of T = 74 +/- 13 MeV at the highest beam energy, a result which is in agreement with previous analyses done with lower transverse momentum data.Comment: 5 pages, 2 figure

    Tofu industry is a domestic industry largely do not have sewage treatment units, wherewastewater directly discharge into sewers or water bodies without treatment. The aims ofstudy observation the ability of constructed wetland using T. latifolia to removal, COD andTSS. The research variations were plant and detention time. Constructed wetland reactorusing plastics with dimension 50, 36, 31cm, in length x width x height and soil mediathickness of 10 cm, 5 cm sand and 5 cm gravel. T. latifolia plant density 0, 0,5, 0,75 and 1g/cm2, and variations detention time 1,2, and 3 day. Optimal results were obtained in plantsTypha latifolia 1 g/cm2 and detention time day to 3 there are COD 200 mg/L and efficiency of92,70%; TSS 153 mg/L with efficiency 87,90%;. Anova analysis results α = 5% show thevalue COD 98,8%; and TSS 92,8%. Wich explains that the plant density factor and detentiontime affect the the concentration reduction COD and TSS

    Penerapan Pembelajaran Dengan Bantuan Bertahap (Scaffolding) Untuk Meningkatkan Aktivitas Dan Prestasi Belajar Matematika Siswa Pada Materi Pokok Trigonometri Kelas X B Semester II Sman 1 Labuapi Tahun Pelajaran 2013/2014

    : Mathematics learning process in X B class of senior high school number 1 Labuapi academic year 2013/2014 had some problems, students are not motivated to learn activity by their self, students meet difficulties in learning mathematics. Those problems causes the low of student's mathematics learning activity and achievement in X B class of senior high school number 1 Labuapi. Therefore, this research aims to solve that problems, by implementing scaffolding learning in teaching trigonometri material trough students in X B class of senior high school number 1 Labuapi academic year 2013/2014. The implementation of scaffolding learning method is held in five (5) steps. The result showed that an increase in the average value from cycle 1 to cycle 3, which is 66,56; 75,28; and 84,50. Mastery learning from cycle 1 to cycle 3 respectively are 33,33%, 66,67%, and 88,89%. In cycle 1, the mean score of students' learning activities is 10, 12, and 17, with quite active, active, and very active category. From this result it can be concluded that implementation of scaffolding learning can improve the mathematics activity and learning achievement in X Bclass students of senior high school number 1 Labuapi in material of trigonometry academic year 2013/2014

    Silicon Nanowire Immunosensor for Detection of 8-Hydroxy-2^|^apos;-Deoxyguanosine Oxidative Stress Cancer Biomarker

    A silicon nanowire-based immunosensor has been developed to determine the presence of 8-hydroxy-2'-deoxyguanosine (8-OHdG). This research demonstrates a process for the detection of 8-OHdG, which is an oxidative stress biomarker, in which elevated concentrations in urine and saliva can act as an indicator of the presence of acute leukaemia, colorectal, breast, lung and prostate cancers. The detection of elevated levels of this biomarker is critical in determining the presence of various mutagenesis and can be used to diagnose early stage cancer before initial symptoms appear. The surface functionalization process has involved the attachment of diazonium salt to the silicon nanowire surface with further stage which involves the reduction of PhNO2 to PhNH2. The antibody targeted against 8-OHdG was subsequently bound to the amine NH2 modified grafted layer of a 370 nm width nanowire. The immunosensor was evaluated through the use of current/voltage electrical probe monitoring in which a 2 μg/ml concentration of 8-OHdG was detected. A further comparison with phosphate buffered saline solution added to the sensor was observed to be negligible. The antibody-functionalised SiNW sensor has been used to detect binding of the 8-OHdG biomarker to the SiNW surface within sixty-seconds of exposure, making this a rapid cancer biomarker test
