Random Vibrations of Nonlinear Continua Endowed with Fractional Derivative Elements

In this paper, two techniques are proposed for determining the large displacement statistics of random exciting continua endowed with fractional derivative elements: Boundary Element Method (BEM) based Monte Carlo simulation; and Statistical Linearization (SL). The techniques are applied to the problem of nonlinear beam and plate random response determination in the case of colored random external load. The BEM is implemented in conjunction with a Newmark scheme for estimating the system response in the time domain in conjunction with repeated simulations, while SL is used for estimating efficiently and directly, albeit iteratively, the response statistics

Structuring and support by Alfven waves around prestellar cores

Observations of molecular clouds show the existence of starless, dense cores, threaded by magnetic fields. Observed line widths indicate these dense condensates to be embedded in a supersonically turbulent environment. Under these conditions, the generation of magnetic waves is inevitable. In this paper, we study the structure and support of a 1D plane-parallel, self-gravitating slab, as a monochromatic, circularly polarized Alfven wave is injected in its central plane. Dimensional analysis shows that the solution must depend on three dimensionless parameters. To study the nonlinear, turbulent evolution of such a slab, we use 1D high resolution numerical simulations. For a parameter range inspired by molecular cloud observations, we find the following. 1) A single source of energy injection is sufficient to force persistent supersonic turbulence over several hydrostatic scale heights. 2) The time averaged spatial extension of the slab is comparable to the extension of the stationary, analytical WKB solution. Deviations, as well as the density substructure of the slab, depend on the wave-length of the injected wave. 3) Energy losses are dominated by loss of Poynting-flux and increase with increasing plasma beta. 4) Good spatial resolution is mandatory, making similar simulations in 3D currently prohibitively expensive.Comment: 13 pages, 8 figures, accepted for publication in A&A.

Hubungan Kecerdasan Emosional Dan Kecerdasan Spiritual Dengan Prestasi Belajar Siswa Di SMP Katolikst. Fransiskus Pineleng

: Learning is a process of change within the human personality, and the change Showed in the form of improved quality and quantity of behavior. Many people things that IQ is important for the people success, but anothers intelligence for make sure people success it`s SQ and EQ Emotional intelligence and Intelligence research Purposes of determine the correlation of emotional intelligence and spiritual intelligence with student achievement. This research method using cross sectional study design, with a sample of 48 students. a sampling technique that uses total sampling. the research instrument used are questionnaires and observation sheets. analysis of data on emotional intelligence was performed using chisquare test was obtained P-Value 0.011. This means that the p-value is smaller than α (0.05) and analysis of data on spiritual intelligence is done using Chi-Square test was obtained PValue 0,000, this means the p-value is smaller than α (0.05). Conclusions are emotional and spiritual intelligence correlation with student achievement

Hubungan Jenis Cairan Dan Lokasi Pemasangan Infus Dengan Kejadian Flebitis Pada Pasienrawat Inap Di RSU Pancaran Kasih Gmim Manado

:More Than 60% of patients who duty The hospital received therapy through IV . IV therapy can be a complication occurred phlebitis . Period Genesis Nosocomial infections Form of phlebitis in Indonesia as much (17.11%). Phlebitis caused by chemical irritation (Infusion fluid types), mechanical (mounting location Infusion), and bacteria. The aim of this research was to determine whether there is a relationship kind of fluid and the incidence of infusion site phlebitis in patients hospitalized in RSU Pancaran Kasih GMIM Manado. Sample is taken by making consecutive sampling technique that is 40 samples. The study design used is analytic survey with cross sectional approach and data were collected using observation sheet.The result of this research with using chi square are (a) relationship between Infusion fluid types with Genesis Phlebitiswhich about p = 0,000, (b) there is a relationship between IV Installation Area with Genesis Phlebitiswhich about p = 0,005.Conclussion(a) there is a relationship between Infusion fluid types with Genesis Phlebitis, (b) there is a relationship between IV Installation Area with Genesis Phlebitis

Zooplankton Community in the Waters of Lab Faculty of Fisheries and Marine Science East Likupang North Minahasa

Tujuan penelitian ini adalah untuk mengetahui jenis, kepadatan, dan struktur komunitas Zooplankton seperti Indeks Keanekaragaman (H\u27), Indeks Dominansi (C), dan Keseragaman (e). Pengambilan sampel dilakukan pada 12 November 2019 mengunakan planktonet sampai kedalaman 10 m dari permukaan laut, dilakukan secara vertikal sebanyak 3 kali pada setiap titik. Berdasarkan hasil pengamatan diperoleh 22 genus 26 spesies dalam 3 kelas yaitu : Paracalanus sp, Rhincalanus sp, Calanus sp., Corycaeus sp, Acrocalanus sp., Oncaea sp, Oithona sp., Scolecithricella sp., Euterpina sp., Eurytemora sp., Centropages sp., Ctenocalanus sp., Eucalanus sp., Pseudocalanus sp., Microsetella sp., Nauplius sp., Squilla sp., Siriella sp., Pseudeuphausia sp., Nematocelis sp., Zoea., Solenocera sp. Kepadatan Relatif tertinggi terdapat pada Paracalanus sp yakni 39.38%. Keanekaragaman (H\u27) zooplankton di dua titik tergolong sedang. Nilai tersebut menunjukkan komunitas organisme dalam kondisi yang kurang beragam. Dan Dominansi (C) menunjukkan tidak ada spesies yang mendominasi di perairan Likupang Timur

Hubungan Respons TIME Perawat Dengan Kepuasan Pasien Di Instalasi Gawat Darurat Rsup Prof. Dr. R. D. Kandou Manado.

Abstrack : This study in the background due to the long emergency emergency patients get the care and left waiting, causing dissatisfaction with the services be given. Aim this study was to determine the relationship of response time nurses with patient satisfaction. Research Design: This study used analytic survey with cross sectional approach where all data relating to the variables measured and observed one at the same time, a sample of 60 respondents. Data were collected by questionnaires fill made by the study and filled by responsden. further data have been collected was processed using SPSS for analysis to the design of analytic survey method with cross sectional approach. The data obtained were processed using the chi-square test with significance (α) = 0.05. The results showed that there is a relationship between the response time to the satisfaction of nurses, patients with a fast time response categories and satisfied 19 (51.4%), 11 people less satisfied (29.7%), while disgruntled 7 (18.9) while the slow response time is not satisfied 10 (43.5%), less satisfied 9 (39.1%), and satisfied 4 people (17.4%). Conclusion The results of this study there was a significant relationship between response time nurses with patient satisfaction, the faster the response time nurses more satisfied patients, and vice versa when the nurse slow response time increasingly dissatisfied patients

A weakly nonlinear Alfvénic pulse in a transversely inhomogeneous medium

The interaction of a weakly nonlinear Alfvénic pulse with an Alfvén speed inhomogeneity in the direction perpendicular to the magnetic field is investigated. Identical to the phase mixing experienced by a harmonic Alfvén wave, sharp transverse gradients are generated in the pulse by the inhomogeneity. In the initial stage of the evolution of an initially plane Alfvénic pulse, the transverse gradients efficiently generate transversely propagating fast magnetoacoustic waves. However, high resolution full MHD numerical simulations of the developed stage of the pulse evolution show that the generation saturates due to destructive wave interference. It is shown that the weakly non-linear description of the generated fast magnetoacoustic wave is well described by the driven wave equation proposed in Nakariakov et al. (1997), and a simple numerical code (2D MacCromack), which solves it with minimal CPU resources, produces identical results to those obtained from the full MHD code (Lare2d, Arber et al. 2001). A parametric study of the phenomenon is undertaken, showing that, contrary to one's expectations, steeper inhomogeneities of the Alfvén speed do not produce higher saturation levels of the fast wave generation. There is a certain optimal gradient of the inhomogeneity that ensures the maximal efficiency of the fast wave generation
