The DS18B20 sensor calibration has been conducted using a fluke hart with a temperature chamber at the center for meteorology, climatology, and geophysics region III Denpasar. The calibration process is done by stabilizing the temperature in the chamber, then the temperature on the DS18B20 sensor and the standard thermometer in the chamber are read and compared. The setpoints used were 10 oC, 20 oC, 30 oC and 40 oC each set point was read four times. The results of the calculation of the standard deviation at each setpoint are  0,39 oC,  0,12 oC,  0,00 oC,  0,00 oC and the results of the uncertainty for each setpoint are 0,65 oC,  0,20 oC,  0,18 oC,  0,18 oC. The results of the DS18B20 sensor calibration using a fluke hart with a temperature chamber obtained the highest standard deviation value of 0,39 oC and the highest uncertainty value was 0,65 oC. This value indicates that the DS18B20 sensor calibrated with a standard tool at the 10 oC set point has not met the standard value applied by WMO, which is ±0.3 oC.

The Impact

Due to global financial crisis, around the all over the world all developing and under developing countries are facing the low trading profit. In most of the developing country like Pakistan, there is low investment level due to political instability. Due to this condition Karachi stock exchange has the worst sell .Karachi stock exchange is known as the oldest and more profitable stock exchange of Pakistan oil and gold prices are attracting investors towards there not in the stock exchange. This thing is the barrier for the progress of the development of the country. This paper is trying to expose that stock market is going to down due to these variables. For checking the impact of oil and gold prices on the Karachi stock exchange. We have used that secondary data for this study. For this purpose we have taken data from Karachi stock exchanges from the period of 1996 to 2013.We have applies correlation matrix for this purpose. the result has shown that KSE 100 has return is 0.014503 and GDP 0.058793 ,gold 0.012026 and oil 0.00919.karachi stock exchange return  has standard value is 0.089982,while gold standard deviation 0.038716 and oil standard deviation value is 0.103375. The correlations have shown that in these markets there is not positive relationship.karachi stock exchange and GDP have inverse relationship with gold market. These results have also shown that oil growth has a significant relationship with KSE100 and GDP.For the predication correlation is not considering an authentic measure.

Monitoring of deformation on Sermo Dam has been widely practiced. One of them is by installing the monitoring point, locate dinside the Sermo Dam area called the micro network, and outside the dam called macro network. The installation of the micro network monitoring point aims to monitor the deformation of the dam due to the volume of water. The macro network monitoring point aims to monitor the effect of the existence of an active fault under the dam. In the last few years, monitoring in Sermo Dam has been done using GNSS technology. This paper intends to present the results of the accuracy represented by the deviation standard value of the measurement point at the macro net on the GNSS observation in 2016 and 2017. The objective is to compare the accuracy resulting from various GNSS processing strategies in observation 2016 and 2017, evaluation of GNSS measurements that can be used as guidance in subsequent GNSS measurements. The result shows that GNSS measurement in 2017 using two IGS reference points (BAKO and COCO) has a better standard deviation value compared to the 2016 measurement by the difference 1-5 mm on the X axis, 1-9 mm on the Y axis, and 1-2 mm on the Z axis. In the GNSS data processing using seven IGS reference points (BAKO, COCO, KARR, DARW, GUUG, PIMO, SHAO) in 2016 mostly has a better standard deviation compared to 2017 measurement except in MAK5 with the difference 0-4 mm on the X axis, 1-10 mm on Y axis, and 0-2 mm on Z axis. As for the value of coordinate data processing in 2016 and 2017on the two processing strategies there are differences in coordinate values that indicate the movement of monitoring points of macro network. However, the vector of the point movement that occurs in the two strategies has a different direction. This requires verification in-depth research and focused on the deformation of the Sermo Dam monitoring point.

Protein Monolayer

The success of the protein monolayer technique for electron microscopy of individual DNA molecules is based on the prevention of aggregation and orientation of the molecules during drying on specimen grids. DNA adsorbs first to a surface-denatured, insoluble cytochrome c monolayer which is then transferred to grids, without major distortion, by touching. Fig. 1 shows three basic procedures which, modified or not, permit the study of various important properties of nucleic acids, either in concert with other methods or exclusively:1) Molecular weights relative to DNA standards as well as number distributions of molecular weights can be obtained from contour length measurements with a sample standard deviation between 1 and 4%.

Purpose The minimum masking level (MML) is the minimum intensity of a stimulus required to just totally mask the tinnitus. Treatments aimed at reducing the tinnitus itself should attempt to measure the magnitude of the tinnitus. The objective of this study was to evaluate the reliability of the MML. Method Sample consisted of 59 tinnitus patients who reported stable tinnitus. We obtained MML measures on two visits, separated by about 2–3 weeks. We used two noise types: speech-shaped noise and high-frequency emphasis noise. We also investigated the relationship between the MML and tinnitus loudness estimates and the Tinnitus Handicap Questionnaire (THQ). Results There were differences across the different noise types. The within-session standard deviation averaged across subjects varied between 1.3 and 1.8 dB. Across the two sessions, the Pearson correlation coefficients, range was r = .84. There was a weak relationship between the dB SL MML and loudness, and between the MML and the THQ. A moderate correlation ( r = .44) was found between the THQ and loudness estimates. Conclusions We conclude that the dB SL MML can be a reliable estimate of tinnitus magnitude, with expected standard deviations in trained subjects of about 1.5 dB. It appears that the dB SL MML and loudness estimates are not closely related.

Fragestellung: Es wurde der Frage nachgegangen, ob sich erfolgreiche Teilnehmer eines ambulanten familienzentrierten Gewichtskontrollprogramms durch spezifische familiäre und psychologische Charakteristiken auszeichnen. Einbezogen wurden die psychosoziale Risikobelastung der Familie, Depressivität und Bindungsstil der Hauptbezugsperson, der Body mass index (BMI) und der BMI-Standardabweichungswert («Standard deviation score», SDS) des teilnehmenden Kindes und der Familienmitglieder sowie die individuelle psychische Belastung des teilnehmenden Kindes. Methodik: Die Daten wurden per Interview und Fragebogen vor dem Behandlungsbeginn erhoben. Von 136 in das Programm aufgenommenen übergewichtigen und adipösen Kindern zwischen 7 und 15 Jahren beendeten 116 das 12-monatige Interventionsprogramm. Von diesen zeigten 100 (85,3 %) eine Reduktion des BMI-SDS und 79 (68.1 %) eine mehr als 5 %ige Reduktion des BMI-SDS. Diese «erfolgreichen» Kinder wurden mit 56 «nicht erfolgreichen» (Abbrecher und Kinder mit einer 5 %igen oder geringeren Reduktion des BMI-SDS) verglichen. Ergebnisse: Nicht erfolgreiche Kinder unterschieden sich von den erfolgreichen durch ein höheres Alter, eine höhere psychosoziale Risikobelastung, Depressivität und einen vermeidenden Bindungsstil der Mutter sowie durch das Vorhandensein adipöser Geschwister. In einer logistischen Regressionsanalyse zeigten sich mütterliche Depressivität und das Vorhandensein adipöser Geschwister als beste und voneinander unabhängige Prädiktoren. Schlussfolgerungen: Um die spezifischen Bedürfnisse der Familien zu erfüllen und einen Misserfolg zu verhindern, sollten zusätzliche Programmbausteine zur spezifischen Unterstützung von Jugendlichen mit adipösen Geschwistern und Müttern mit Depressionen und vermeidenden Bindungsstil entwickelt werden. Die Wirksamkeit dieser Module muss dann in weiteren Studien überprüft werden.
