Kondisi Bawah Permukaan di Sekitar Tebing Watukosek

Salah satu penyebab munculnya semburan lumpur Sidoarjo yang masih diperdebatkan hingga saat ini yaitu mengenai reaktivasi patahan watukosek. Studi yang telah dilakukan sebelumnya menunjukkan adanya manifestasi di permukaan akibat patahan watukosek, contohnya Tebing Watukosek dan pembelokan geomorfologi Kali Porong. Penelitian dengan menggunakan metode tahanan jenis dilakukan untuk memetakan patahan yang berada di daerah Kali Porong dan Patahan Watukosek. Lintasan yang digunakan memiliki bentangan 400m dengan arah Barat – Timur untuk memotong patahan yang berarah Barat Daya – Timur Laut dari Gunung Penanggungan menuju semburan lumpur Sidoarjo. Kedalaman pengukuran mencapai ±74.8m dengan anomali tahanan jenis terendah 1.05 Ohm.m hingga yang tertinggi 33.3 Ohm.m

Many plants for ingredients there are Curcuma xanthorrhiza Roxb, Andrographis paniculata Ness, Orthosiphon grandiflora Bold, Curcuma domestica Val, Zingiber officinale Roxb, Phaleria macrocarpa Boerl, Carica papaya L and Loranthus sp

A SERVQUAL approach to identifying the influences of service quality on leasing market segment in the German financial sector

Purpose: The purpose of this paper is to determine the nature of the relationship between service quality and desired customer behaviours in the leasing market using an appropriate service quality measurement model. We take a step further by recognising the possible differences in influence of service quality in private and corporate customers, and those business dealings with low, medium and high lease values. Design/methodology/approach: We use deduction method to test the SERVQUAL in the German leasing market and the relationship between customer satisfaction and desired behavioural outcomes. The developed questionnaire is based on the 22 item scale of the SERVQUAL approach. Samples are selected based on convenience sampling. Findings: We found differences in the levels of inflence by SERVQUAL dimensions on corporate and private customers as well as among those customers with different leasing contract values. From the regression analyses, it is clear that 'assurance' from the leasing company is the most common SERVQUAL dimension that has significant impact on overall service quality perceptions and obtaining customers satisfaction and loyalty (behavioural outcomes). Originality/Value: We recognised that all financial services are not created equally to meet customer demands. Hence, the customer expectations of service quality from these services will be different. We contributed to the marketing literature by studying customer perceptions of service quality by specifying financing aspects of financial services, i.e. leasing. We further contributed to the literature of SERVQUAL model in financial services by dividing customers into two different types of customers and those with diverse leasing contract values. We found that priorities given on service quality dimensions by them are different. These concepts were never considered in the literature. This also implies that future studies on financial services marketing need to recognise such differences in the research

Einstein's fluctuation formula. A historical overview

A historical overview is given on the basic results which appeared by the year 1926 concerning Einstein's fluctuation formula of black-body radiation, in the context of light-quanta and wave-particle duality. On the basis of the original publications (from Planck's derivation of the black-body spectrum and Einstein's introduction of the photons up to the results of Born, Heisenberg and Jordan on the quantization of a continuum) a comparative study is presented on the first line of thoughts that led to the concept of quanta. The nature of the particle-like fluctuations and the wave-like fluctuations are analysed by using several approaches. With the help of the classical probability theory, it is shown that the infinite divisibility of the Bose distribution leads to the new concept of classical poissonian photo-multiplets or to the binary photo-multiplets of fermionic character. As an application, Einstein's fluctuation formula is derived as a sum of fermion type fluctuations of the binary photo-multiplets.Comment: 34 page

Einstein's quantum theory of the monatomic ideal gas: non-statistical arguments for a new statistics

In this article, we analyze the third of three papers, in which Einstein presented his quantum theory of the ideal gas of 1924-1925. Although it failed to attract the attention of Einstein's contemporaries and although also today very few commentators refer to it, we argue for its significance in the context of Einstein's quantum researches. It contains an attempt to extend and exhaust the characterization of the monatomic ideal gas without appealing to combinatorics. Its ambiguities illustrate Einstein's confusion with his initial success in extending Bose's results and in realizing the consequences of what later became to be called Bose-Einstein statistics. We discuss Einstein's motivation for writing a non-combinatorial paper, partly in response to criticism by his friend Ehrenfest, and we paraphrase its content. Its arguments are based on Einstein's belief in the complete analogy between the thermodynamics of light quanta and of material particles and invoke considerations of adiabatic transformations as well as of dimensional analysis. These techniques were well-known to Einstein from earlier work on Wien's displacement law, Planck's radiation theory, and the specific heat of solids. We also investigate the possible role of Ehrenfest in the gestation of the theory.Comment: 57 pp

Random walk with barriers: Diffusion restricted by permeable membranes

Restrictions to molecular motion by barriers (membranes) are ubiquitous in biological tissues, porous media and composite materials. A major challenge is to characterize the microstructure of a material or an organism nondestructively using a bulk transport measurement. Here we demonstrate how the long-range structural correlations introduced by permeable membranes give rise to distinct features of transport. We consider Brownian motion restricted by randomly placed and oriented permeable membranes and focus on the disorder-averaged diffusion propagator using a scattering approach. The renormalization group solution reveals a scaling behavior of the diffusion coefficient for large times, with a characteristically slow inverse square root time dependence. The predicted time dependence of the diffusion coefficient agrees well with Monte Carlo simulations in two dimensions. Our results can be used to identify permeable membranes as restrictions to transport in disordered materials and in biological tissues, and to quantify their permeability and surface area.Comment: 8 pages, 3 figures; origin of dispersion clarified, refs adde

MULTIPLE HIGH CURRENT BUNCHES IN PEP-II

Operation with colliding beams at PEP-II has progressed remarkably well with over half the design specific luminosity and 5:2 10 32 cm,2s,1 in multiple bunches demonstrated during the last commissioning period before installation of the BABAR detector. Further luminosity increases are anticipated as the vertical beam size is reduced and beam currents are raised towards design values. At high currents interesting multibunch dynamics, which depend strongly on current distribution, have been observed during single-beam commissioning studies. Transverse beam instabilities nominally controlled using bunch-by-bunch feedback were observed to be significantly suppressed, in the absence of feedback, with beams in collision.
