Energy spectra and quadrupole transition probabilities of 124-130Ba

In this paper, we have studied the energy spectra and B(E2) transition probabilities of 124-130Ba isotopes in the shape phase transition region between the spherical and gamma unstable deformed shapes. We have used a transitional Interacting Boson Model Hamiltonian which is based on affine SU(1,1) Lie Algebra in the both IBM-1 and 2 versions and also the Catastrophe theory in combination with a coherent state formalism to generate energy surfaces and determine the exact values of control parameters. Our results for control parameters suggest a combination of U(5) and SO(6) dynamical symmetries in this isotopic chain. Also, the theoretical predictions can be rather well reproduce the experimental counterparts when the control parameter is approached to the SO(6) limit.Comment: 22 pages, 3 figures, 5tables. arXiv admin note: text overlap with arXiv:1509.02282; text overlap with arXiv:1507.06933 by other authors without attributio

Assessment of the knowledge and attitude of the pregnant women who referred to Iran University of Medical Sciences in 2005 toward Islams hygienic instructions during their pregnancy and breast feeding periods

Background and aim: Pregnancy and infancy are as diving profits, which are of the most enjoyable times of women. Islams living doctrine recommends some adwises for pregnant women to have healthy generation with good physical, mental and social dimensions. Therefore, the aim of this study was to evaluate the knowledge and attitude of the pregnant women who referred to Iran University of Medical Sciences in 2005 toward Islam’s hygienic instructions during their pregnancy and breast feeding period. Methods: In this descriptive-analytical study, a total of 300 pregnant women were selected from parental care unite using multistage sampling. The data was gathered through self-reporting questionnaire which contained some questions about the individuals characteristics, attitude and awareness. Subsequently, using χ2, Pearson correlation and Spearman tests, data were analyzed. Results: The percentage of the knowledge about the Islams healthy instructions during pregnancy was graded: good 20.6%, average 64.7% and poor 14.7%. During breast-feeding, the knowledge was 6.3% good, 77% average and 16.7% poor. There was a positive relationship between the women’s level of education and their knowledge about Islamic trainings. The attitude of the women about the instructions during their pregnancy was positive in 68.3% and negative in 31.7% of them. This attitude during breast feeding was positive in 64% and negative in 36% of the women studied. There was relationship between the knowledge toward the instructions and the level of education during pregnancy and also between this knowledge and the number of pregnancy and the level of education (p<0.01). Conclusion: In addition to moderate knowledge and positive attitude of most of samples and undeniable religious force, on promoting health, recommended that health managers programmed to pregnant women care based on Islamic recommendations and health care workers have more attention in their education training

زمینه و هدف: تحقیق حاضر برای بررسی میزان اعتبار این دستگاه در اندازه گیری زوایای کایفوز سینه ای و لوردوز کمری در مقایسه با عکس رادیوگرافی و همچنین تکرارپذیری درون و بین آزمونگر آن بود. روش بررسی: برای بررسی میزان اعتبار دستگاه اسپاینال موس در اندازه گیری زوایای کایفوز سینه ای و لوردوز کمری، تعداد 20 نفر از افراد مراجعه کننده به یکی از مراکز تصویربرداری پزشکی شهر تهران که قرار بود بر اساس تجویز پزشک متخص عکس رادیوگرافی کامل ستون فقرات از نمای نیمرخ تهیه کنند انتخاب شدند. معیارهای ورود و خروج آن ها بررسی شد و اندازه گیری ها با دو روش در یک روز و بدون فاصله انجام گردید، در نهایت زاویه ها در عکس رادیوگرافی به روش کوب و در اسپاینال موس با توجه به نتایج ثبت شده بر روی نمایشگر، با روش آماری همبستگی پیرسون مقایسه شدند. همچنین برای بررسی تکرارپذیری درون آزمونگر 30 نفر از دانشجویان پسر دانشگاه تهران به صورت تصادفی وارد تحقیق شدند تا در سه نوبت در سه روز متوالی اندازه گیری ها تکرار شود، همچنین برای تکرارپذیری بین آزمونگر 15 نفر از دانشجویان پسر دانشگاه تهران در دو نوبت با فاصله زمانی یک دقیقه توسط دو آزمونگر اندازه گیری شدند. در نهایت نتایج با روش همبستگی درونی بررسی قرار گرفت. یافته ها: دستگاه اسپاینال موس از اعتبارپذیری مطلوبی در مقایسه با رادیوگرافی در اندازه گیری زاویه کایفوز سینه ای (0/001=P، 0/81=r) و لوردوز کمری (0/001=P، 0/86=r) برخوردار است. همچنین تکرارپذیری درون و بین آزمونگر دستگاه اسپاینال موس نیز در اندازه گیری زوایای کایفوز سینه ای به ترتیب (0/92=ICC، 0/79ICC=) و لوردوز کمری (0/89ICC=، 0/87ICC=) مطلوب بود. نتیجه گیری: استفاده از دستگاه اسپاینال موس به عنوان یک وسیله غیرتهاجمی ایمن و جایگزینی مناسب برای عکس رادیوگرافی در اندازه گیری زوایای کایفوز سینه ای و لوردوز کمری توصیه می شود

Legionella pneumophila strain 130b evades macrophage cell death independent of the effector SidF in the absence of flagellin

International audienceThe human pathogen Legionella pneumophila must evade host cell death signaling to enable replication in lung macrophages and to cause disease. After bacterial growth, however, L. pneumophila is thought to induce apoptosis during egress from macrophages. The bacterial effector protein, SidF, has been shown to control host cell survival and death by inhibiting pro-apoptotic BNIP3 and BCL-RAMBO signaling. Using live-cell imaging to follow the L. pneumophila-macrophage interaction, we now demonstrate that L. pneumophila evades host cell apoptosis independent of SidF. In the absence of SidF, L. pneumophila was able to replicate, cause loss of mitochondria membrane potential, kill macrophages, and establish infections in lungs of mice. Consistent with this, deletion of BNIP3 and BCL-RAMBO did not affect intracellular L. pneumophila replication, macrophage death rates, and in vivo bacterial virulence. Abrogating mitochondrial cell death by genetic deletion of the effectors of intrinsic apoptosis, BAX, and BAK, or the regulator of mitochondrial permeability transition pore formation, cyclophilin-D, did not affect bacterial growth or the initial killing of macrophages. Loss of BAX and BAK only marginally limited the ability of L. pneumophila to efficiently kill all macrophages over extended periods. L. pneumophila induced killing of macrophages was delayed in the absence of capsase-11 mediated pyroptosis. Together, our data demonstrate that L. pneumophila evades host cell death responses independently of SidF during replication and can induce pyroptosis to kill macrophages in a timely manner

A Stable Matching Assignment for Cancer Treatment Centers using Survival Analysis

The treatment of cancer is one of the most discussed issues in the realm of contemporary public health research. One of the primary concerns of both the general public and the government is the development of the most effective cancer treatment at the most affordable price. This is due to the fact that the number of persons diagnosed with cancer increases on an annual basis. Within the scope of this project, we propose the development of a system for the recommendation of treatment centers. This system would initially select patients who posed a higher risk value, and then it would recommend the most appropriate cancer treatment center for those patients based on their income and the location where they lived using a stable matching algorithm

Work functions, ionization potentials, and in-between: Scaling relations based on the image charge model

We revisit a model in which the ionization energy of a metal particle is associated with the work done by the image charge force in moving the electron from infinity to a small cut-off distance just outside the surface. We show that this model can be compactly, and productively, employed to study the size dependence of electron removal energies over the range encompassing bulk surfaces, finite clusters, and individual atoms. It accounts in a straightforward manner for the empirically known correlation between the atomic ionization potential (IP) and the metal work function (WF), IP/WF$\sim$2. We formulate simple expressions for the model parameters, requiring only a single property (the atomic polarizability or the nearest neighbor distance) as input. Without any additional adjustable parameters, the model yields both the IP and the WF within $\sim$10% for all metallic elements, as well as matches the size evolution of the ionization potentials of finite metal clusters for a large fraction of the experimental data. The parametrization takes advantage of a remarkably constant numerical correlation between the nearest-neighbor distance in a crystal, the cube root of the atomic polarizability, and the image force cutoff length. The paper also includes an analytical derivation of the relation of the outer radius of a cluster of close-packed spheres to its geometric structure.Comment: Original submission: 8 pages with 7 figures incorporated in the text.
