Collisional Energy Loss of Non Asymptotic Jets in a QGP
We calculate the collisional energy loss suffered by a heavy (charm) quark
created at a finite time within a Quark Gluon Plasma (QGP) in the classical
linear response formalism as in Peigne {\it et al.} \cite{peigne}. We pay close
attention to the problem of formulating a suitable current and the isolation of
binding and radiative energy loss effects. We find that unrealistic large
binding effects arising in previous formulations must be subtracted. The finite
time correction is shown to be important only for very short length scales on
the order of a Debye length. The overall energy loss is similar in magnitude to
the energy loss suffered by a charge created in the asymptotic past. This
result has significant implications for the relative contribution to energy
loss from collisional and radiative sources and has important ramifications for
the ``single electron puzzle'' at RHIC.Comment: 15 Pages, 11 figures, revte
Membangun Aceh Melalui Pendidikan (Studi Analisis Konsep KOPELMA Darussalam Ali Hasjmy)
This study aimed to investigate the background of the establishment of KOPELMA Darussalam, the concept of KOPELMA Darussalam proposed by Ali Hasjmy, and the relevance of Ali Hasjmy's educational thoughts with Aceh’s development through education. The study used a library research design, employing the primary data from Ali Hasjmy’s writings and the secondary data from two figures who had lived with and were close to Ali Hasjmy. The data were analyzed by using a descriptive analysis method. The results of the study revealed that Ali Hasjmy founded KOPELMA Darussalam as a manifestation of his educational, cultural, and political thoughts. This, in turn, gave birth to a big concept to Aceh’s development towards modernization, equipped with Islamic sharia, Acehnese culture and traditions, and science, after Aceh was hit by prolonged social conflict. The concept of KOPELMA Darussalam proposed by Ali Hasjmy intended to create KOPELMA Darussalam as a symbol of peace and love, a place to produce faithful and devoted humans to the religion and the nation, a place to establish science for humanity, a place to build "Pancasila"-instilled citizens, a symbol for the collapse of educational secularism and dichotomy of science in Aceh, a source of the realization of the Acehnese aspirations (i.e., of the ideals of justice and prosperity), an oasis of knowledge, and a manufacturer of people with devoted souls and spirit to the religion and the nation. To date, Ali Hasjmy's educational thinking about "The Ideal Concept of Darussalam (Abode of Peace)" is still relevant with the basis for Aceh's development through education
Knowledge Transmission among Preservation Practitioners in Dubai
The economic importance and strategic position of the Middle East have epistemologically twisted most of its true cultural recognition. Both late urban definition and mutual communications have crippled some of its Bedouin societies from proving their participation in global culture. Each society has some to share in human accumulative know-how, but geo-political environments and barriers have lots to do in such mutuality. Many investigations have proved effective transmission of knowledge, but also pointed out black and mysterious zones within the societies themselves. The main obstacle is generated from the oral Arabic culture itself, when episteme is conditioned with biological memory, synchronized interchange and ethical referrals. The necessity of scientific and standard approaches of archeological research and architectural preservation exist and is proven to be of value in preservation of architectural knowledge. However, it is distinctly a hard task to use such standards to challenge the fast urbanization and social developments of our time. While archeological research is apart from contemporary explanations, preservation research is proposed as being more important. Investigations on building concepts require in-depth analysis of habits and behaviors of both craftsmen and beneficiaries, which is a folkloric approach. The lack of linguistic research blocks sufficient use of traditional poetry, literature and folklore to reproduce evidence of technologies from the past. Obviously, the limited natural resources in the Arabian Peninsula have simplified both the architectural setting and construction methodologies and hidden the natural creativity or know-how of earlier societies. Unique architectural contributions need not be limited to definitions of monumental constructs or other impressive achievements. Rather, architecture is defined mainly by cultural and epistemological expressions. This is important in discovering the continuity and distribution of societies in human and global civilization. It is also important to include Middle Eastern architecture in the ongoing intensive identification of architectural perspectives. Despite the late attention that has been given to preservation activities in Arabic States in the Persian Gulf, it is time to start assessment and evaluation of architectural traditions to challenge the remarkably fast development that is occurring. Various organizational, social and political factors are involved in the few serious attempts that have been made. Interventions by ambitious ruling powers have alternatively supported or thwarted such efforts. Lessons can be learned from these examples that highlight effective approaches useful in maintaining the immovable heritage elements in underdeveloped countries. These elements contain most of the remaining important and creative features of human architectural inputs that now benefit most of the globe. International involvement may be drawn to fill scientific gaps and requirements, while paths for serious cooperation are blocked with either hesitation or insufficient awareness of the matter. Bridging the true knowledge needs not only willingness, but also serious identification of both obvious and unconscious motivations that rule decision-making and practice. The conclusions may support the ongoing development of methodologies and professional practices
HAM dalam Perspektif Ilmu-ilmu Syariah
Transformation of the concept and the idea of human rights values to students early on of course be necessary to do, given the new generations is what will be the successor to the perpetrators of the world. It is expected that all students have the same attention to human values.ملخص: التحول من مفهوم وفكرة قيم حقوق الإنسان للطلاب في وقت مبكر بطبيعة الحال يكون من الضروري القيام به، نظرا للأجيال الجديدة هو ما سوف يكون خلفا لمرتكبي العالم. ومن المتوقع أن جميع الطلاب لديهم نفس القدر من الاهتمام إلى القيم الإنسانية
