Parton picture for the strongly coupled SYM plasma

Deep inelastic scattering off the strongly coupled N=4 supersymmetric Yang-Mills plasma at finite temperature can be computed within the AdS/CFT correspondence, with results which are suggestive of a parton picture for the plasma. Via successive branchings, essentially all partons cascade down to very small values of the longitudinal momentum fraction x and to transverse momenta smaller than the saturation momentum Q_s\sim T/x. This scale Q_s controls the plasma interactions with a hard probe, in particular, the jet energy loss and its transverse momentum broadening.Comment: 4 pages, Talk given at Quark Matter 2008: 20th International Conference on Ultra-Relativistic Nucleus Nucleus Collisions (QM 2008), Jaipur, India, 4-10 Feb 200

Survey on the Potency of Cow Milk Dangke as an Alternative to Buffalo Milk Dangke in Enrekang, South Sulawesi

The scarcity of buffalo milk caused farmers in Enrekang district switch to use cow's milk as a raw material for the manufacture of dangke. This study aims to explore the potential of dangke milk cows from various aspects in the field. Information on population and daily milk production of dairy cows and buffalo, as well as questionnaire data of dangke consumers of Enrekang were obtained in Enrekang district, while data of dangke consumer of not Enrekang were collected with organoleptic tests and questionnaires. Determination of respondents Enrekang with simple random sampling while respondents are not Enrekang with purposive sampling. Data were analyzed by descriptive statistics, independent two-sample t test and chi squared test. The potential benefits of cow milk dangke compared to cow buffalo dangke is that with the same quality (moisture, fat, protein, ash, and pH value) cow???s milk dangke has higher raw material availability, cheaper price, easier attainability, widely accepted by Enrekang consumer population, preferred by the non-Enrekang consumer population, and also possess colour and flavor that is preferred by consumers

Karakteristik Daging Dengan Penambahan NaCl Pada Berbagai Waktu Aging Post Mortem

It is important to maintain meat characteristics after slaughtering because its relationship with preferences and economics values of meat and meat product. Salt addition is an alternative. The aim of this research was to observe influence of salt addition on meat characteristics during the first 7 day of post mortem aging. Meat sample was divided into three groups of salt added treatments : 1) without salt addition, 2) salt added at one day prior to aging, and 3) salt added every day along aging period. The results showed that salt added at the zero day was to increase pH, solubility of salt-soluble protein, and water holding capasity (WHC) to a higher level compared to the other two treatments. Although salt addition may increased the meat characteristics, decreasing these characteristics could not be avoided when the meat stored for 7 day post mortem aging

A computational approach in analyzing the empathy to online donations during COVID-19

The COVID-19 pandemic has a negative impact on many aspects of life. The global economic downturn is one of these negative consequences. Nonetheless, even though everyone feels the threat of this pandemic for themselves, some people still have the empathy to help others. An empirical analysis of this empathy attitude is expected to be a catalyst in realizing a social force for the community to work together to combat this pandemic. This study will look at how people felt about donating during the COVID-19 pandemic on Twitter. The goals of this study are to (1) compare differences in donor desire before and during the COVID-19 pandemic using the developed model, and (2) determine whether there is a significant difference in empathy for donating before and during the pandemic. This study employs computational social science (CSS) techniques to achieve this goal. The data was obtained from Twitter using the keyword "donation" in the 24 months preceding the pandemic and in the 24 months following the pandemic's arrival in Indonesia. Data analysis includes hypothesis testing using Mann-Whitney and Cohen's D statistical tests, showing a significant increase in online donation support among Indonesian Twitter users since the COVID-19 pandemic hit. From the results of data processing data obtained 159.995 data in accordance with the criteria to be analyzed. From the results of the Mann-Whitney test, all variables showed significant results between before and during the Covid-19 pandemic and in the results of the Cohen's d test, all variables got a large effect size. From the results of the two tests, it can open Twitter social media users who have increased empathy to donate during the Covid-19 pandemic in Indonesi

Survey on Characteristics of Processing and Quality of Dangke Milk Cows in Enrekang District, South Sulawesi

The development of the processing industry of dangke milk cows in Enrekang district had an important role in support of the improvement of national milk consumption and absorption of milk cows of local farmers. The purpose of research is to describe of the characteristics of the processing of dangke milk cows consisting of methods of manufacture and storage, as well as the quality of dangke in Enrekang district. This research is a descriptive survey. The respondents are 60 people manufacturers dangke milk cows which selected by simple random sampling. Data on the characteristics of dangke processing collected through observation and interviews with open-ended questionnaire, whereas quality of dangke (moisture, fat, protein, ash, and pH) were measured by AOAC method (1995). Data were analyzed with descriptive statistics. Conclusion of this study is that the method of manufacture of dangke milk cows includes heating of the milk, the addition of papaya latex solution, filtering and printing of the curd, and packaging products are varied quantitatively cause the quality of dangke is diverse. Dangke storage method allows a reduction of the quality of the physical and microbiological dangke milk cows

Dilute Nuclear Matter in Chiral Perturbation Theory

We use chiral perturbation theory to compute the effective nucleon propagator in an expansion about low density in the chiral limit. We neglect four-nucleon interactions and focus on pion exchange. Evaluating the nucleon self-energy on its mass shell to leading order, we show that the effective nucleon mass increases by a small amount. We discuss the relevance of our results to the structure of compact stars.Comment: Manuscript rewritten, especially conclusions about mass shifts; contact terms cannot be neglected.
