A method to estimate weight and dimensions of aircraft gas turbine engines. Volume 1: Method of analysis

Weight and envelope dimensions of aircraft gas turbine engines are estimated within plus or minus 5% to 10% using a computer method based on correlations of component weight and design features of 29 data base engines. Rotating components are estimated by a preliminary design procedure where blade geometry, operating conditions, material properties, shaft speed, hub-tip ratio, etc., are the primary independent variables used. The development and justification of the method selected, the various methods of analysis, the use of the program, and a description of the input/output data are discussed

Analisis Permintaan dan Penawaran Beras di Propinsi Jambi

The rice production growth that was gotten by Jambi Province with production growth rate of 0,54% can not fully contribute society need that was continuously increasing. Therefore, it can cause unbalance between supply and demand. The objective of research is to know the picture of rice supply and demand and influenced variables on rice supply and demand in Jambi. The simultan model was used to predict factors that influenced rice supply and demand. The research was conducted in Jambi Province on September to December 2009. The primary data needed in this research was time series data from 1996 – 2008. The research result showed that simultaneously rice price factor, the number population and income per capita was significant on demand. And also factor of average rice price, Bangkok rice price, import rice price, hybrid seed, acreage, season, and time trend were influencing significantly on supply. From elasticity value was fortunately all variables that was influencing rice demand and supply in Jambi Province was inelastic

Analisis Hubungan Faktor Sosial Ekonomi dengan Partisipasi Anggota Kelompoktani Kelas Pemula pada USAhatani Padi Sawah di Kecamatan Sekernan Kabupaten Muaro Jambi

Penelitian ini bertujuan untuk mengetahui partisipasi petani pada kelompok tani kelas pemula di Kecamatan Sekernan, untuk melihat hubungan faktor sosial ekonomi (pendidikan, luas lahan garapan, jumlah anggota keluarga, dan pendapatan) terhadap partisipasi anggota dalam kelompok tani pemula Di Kecamatan Sekernan Kabupaten Muaro Jambi.Penelitian ini dilakukan di Kecamatan Sekernan, lokasi penelitian ini dilakukan secara sengaja dengan pertimbangan Kecamatan Sekernan merupakan daerah sentra produksi tanaman padi sawah di Provinsi Jambi.Sampel pada penelitian ini adalah petani padi sawah kelas pemula.Data yang dihimpun dari penelitian ini adalah data primer dan data sekunder.Data yang diperoleh dari hasil penelitian akan disederhanakan dengan menggunakan tabulasi, kemudian dianalisis secara deskriptif melalui scoring dan persentase.Untuk melihat pengaruh tinggi atau rendah faktor sosial ekonomi denganpartisipasianggota kelompok tani kelas pemula pada USAhatni padi sawah digunakan analisis statistik non parametrik melalui Uji Chi-Square (Siegel, 1997).Penelitian memperjelas bahwa tinggi rendahnya faktor sosial ekonomi berhubungan nyata dengan partisipasi anggota kelompok tani kelas pemula pada USAhatani padi sawah di Kecamatan Sekernan Kabupaten Muaro Jambi

Decision making and model M. Mishel. Accept or not accept replacement surgery knee prosthetic

Introducción: La artroplastia total de rodilla (PTR) es eficaz en el alivio del dolor y la función en los casos de artrosis de rodilla (AR) grave. Representa un problema de salud pública por su prevalencia. A pesar de los resultados clínicos obtenidos con la PTR, diversos estudios refieren que entre un 14-30% de pacientes se muestran insatisfechos con el resultado, al no alcanzar los beneficios esperados, lo que conlleva que otros desestimen el tratamiento quirúrgico. El modelo de cuidados de M. Mishel pertenece al paradigma de la transformación, parte de la teoría social crítica e incorpora principios de la teoría del caos para elaborar su teoría de la incertidumbre; la enfermedad crónica desencadena un desequilibrio y las personas que la experimentan pueden incorporar esta incertidumbre para adquirir un nuevo sentido de la vida

Coherent QED, Giant Resonances and (e+e−)(e^{+}e^{-}) Pairs in High Energy Nucleus-Nucleus Collisions

We show that the coherent oscillations of the e.m. field induced by the collective quantum fluctuations of the nuclear matter field associated with the giant resonances, with frequencies $\omega_{A}\simeq 78A^{-{1/3}}$ MeV, give rise to a significant $(e^+e^-)$ pair production in high energy Heavy Ion collisions. The approximate parameterless calculation of such yield is in good agreement with recent experimental observations.Comment: 27 pages, 13 figure

Sex chromosome positions in human interphase nuclei as studied by in situ hybridization with chromosome specific DNA probes

Two cloned repetitive DNA probes, pXBR and CY1, which bind preferentially to specific regions of the human X and Y chromosome, respectively, were used to study the distribution of the sex chromosomes in human lymphocyte nuclei by in situ hybridization experiments. Our data indicate a large variability of the distances between the sex chromosomes in male and female interphase nuclei. However, the mean distance observed between the X and Y chromosome was significantly smaller than the mean distance observed between the two X-chromosomes. The distribution of distances determined experimentally is compared with three model distributions of distances, and the question of a non-random distribution of sex chromosomes is discussed. Mathematical details of these model distributions are provided in an Appendix to this paper. In the case of a human translocation chromosome (XqterXp22.2::Yq11Y qter) contained in the Chinese hamster x human hybrid cell line 445 x 393, the binding sites of pXBR and CY1 were found close to each other in most interphase nuclei. These data demonstrate the potential use of chromosome-specific repetitive DNA probes to study the problem of interphase chromosome topography
