Stories of Syrian Refugees from Za’atari- The Second Largest Refugee Camp in the World: A Review of Salam Neighbor

Salam Neighbor is a moving documentary which explores the human rights issues plaguing Syrian refugees. Two young film makers, Zach Ingrasci and Chris Temple, immerse themselves in Za’atari, the second largest refugee camp in the world, located just across the Syrian border in Jordan and home to over 85,000 refugees. They provide the viewer with an inside understanding of how refugee camps work and they humanize Muslim refugees. They are warmly welcomed into the camp and they are befriended by refugees like Ismail, Raouf, and Ghoussoon. The despair and vulnerability of these individuals who have chosen peace over war is palpable

The Impact of Rural Poverty on Women\u27s Health Outcomes in Ethiopia: A Review of A Walk to Beautiful

It is estimated that 2-3 million women worldwide suffer from the debilitating effects of birth injuries such as fistulas. This hidden epidemic is both preventable and highly curable, yet poor women, especially those who live in the rural areas of underdeveloped countries continue to be profoundly negatively impacted physically, psychologically, and socially by this condition. The moving documentary, A Walk to Beautiful, highlights this global problem

The Intersectionality of Gender, Rights, and Privilege: A Comparative Analysis of 127 Countries (Preprint)

This study provides a macro-level comparison of the rights and privileges that women have around the world through the development of a multi-dimensional index of pro-woman states. This is important because states that score highly on the index provide models for decreasing gender inequalities and increasing human rights for women worldwide. Cross-national differences in female education, employment, reproductive freedom, and participation in state policy formation are explored. Pro-woman states have policies that are associated with higher levels of education, income, and satisfaction. An understanding of the rights and privileges provided in pro-woman states can be used to restructure the welfare state to encourage the empowerment of women and the development of more equal societies

State dependent fluorescence yields through the core valence Coulomb exchange parameter

Total and partial fluorescence yield PFY L edge x ray absorption spectra differ from the transmission x ray absorption spectra XAS through state dependent fluorescence yield across the XAS. For 3d1 to 3d9 in octahedral symmetry we apply simulations of PFY and XAS and show how the atomic 2p3d Coulomb exchange parameter Gpd governs the differences in the L3 L2 L3 branching ratio between PFY and XAS. Gpd orders the XAS final states following Hund s rules creating a strong state dependent fluorescence decay strength variation across the XAS leading to the differences between PFY and XA

Determining Sizes of Particles in a Flow from DPIV Data

A proposed method of measuring the size of particles entrained in a flow of a liquid or gas would involve utilization of data from digital particle-image velocimetry (DPIV) of the flow. That is to say, with proper design and operation of a DPIV system, the DPIV data could be processed according to the proposed method to obtain particle sizes in addition to particle velocities. As an additional benefit, one could then compute the mass flux of the entrained particles from the particle sizes and velocities. As in DPIV as practiced heretofore, a pulsed laser beam would be formed into a thin sheet to illuminate a plane of interest in a flow field and the illuminated plane would be observed by means of a charge-coupled device (CCD) camera aimed along a line perpendicular to the illuminated plane. Unlike in DPIV as practiced heretofore, care would be taken to polarize the laser beam so that its electric field would lie in the illuminated plane, for the reason explained in the next paragraph. The proposed method applies, more specifically, to transparent or semitransparent spherical particles that have an index of refraction different from that of the fluid in which they are entrained. The method is based on the established Mie theory, which describes the scattering of light by diffraction, refraction, and specular reflection of light by such particles. In the case of a particle illuminated by polarized light and observed in the arrangement described in the preceding paragraph, the Mie theory shows that the image of the particle on the focal plane of the CCD camera includes two glare spots: one attributable to light reflected toward the camera and one attributable to light refracted toward the camera. The distance between the glare spots is a known function of the size of the particle, the indices of refraction of the particle material, and design parameters of the camera optics. Hence, the size of a particle can be determined from the distance between the glare spots. The proposed method would be implemented in an algorithm that would automatically identify, and measure the distance between, the glare spots for each particle for which a suitable image has been captured in a DPIV image frame. The algorithm (see figure) would begin with thresholding of data from the entire image frame to reduce noise, thereby facilitating discrimination of particle images from the background and aiding in the separation of overlapping particles. It is important not to pick a threshold level so high that the light intensity between a given pair of glare spots does not fall below the threshold value, leaving the glare spots disconnected. The image would then be scanned in a sequence of rows and columns of pixels to identify groups of adjacent pixels that contain nonzero brightnesses and that are surrounded by pixels of zero brightness. Each such group would be assumed to constitute the image of one particle. Each such group would be further analyzed to determine whether the image was saturated; saturated particle images must be rejected because the locations of glare spots in saturated images cannot accurately be determined. Within each unsaturated particle image, the centroids (deemed to be the locations) of the glare spots would be determined by means of gradients of brightness distributions and three-point horizontal and three-point vertical Gaussian estimates based on the brightness values of the brightest pixels and the pixels adjacent to them. If the brightness of a given particle image contained only one peak, then it would be assumed that a second glare spot did not exist and that image would be rejected

SYNTHESIS, INTRACELLULAR DISTRIBUTION, AND SECRETION OF IMMUNOGLOBULIN AND H-2 ANTIGEN IN MURINE SPLENOCYTES

A/J spleen cells were labeled with [3H]leucine and at intervals thereafter were homogenized and separated into microsomes and cell sap. Ig and H-2 antigens were assayed in the cell fractions and cell supernatants using immunoprecipitation. In addition, cells labeled by enzymatic radioiodination were incubated to determine the rates of release of Ig and H-2 antigens from the surface. The results indicate that the majority of Ig and H-2 antigens remain membrane bound throughout their intracellular life. In contrast to Ig, H-2 antigens are neither secreted nor shed from the cell surface. It is suggested that Ig is a peripheral protein of the cell membrane, whereas H-2 antigens are integral ones. The release of Ig on a fragment of plasma membrane could occur at fixed cell surface areas that contain no H-2 antigens or from which they have migrated before release

Laser Anemometer Measurements of the Flow Field in a 4:1 Pressure Ratio Centrifugal Impeller

A laser-doppler anemometer was used to obtain flow-field velocity measurements in a 4:1 pressure ratio, 4.54 kg/s (10 lbm/s), centrifugal impeller, with splitter blades and backsweep, which was configured with a vaneless diffuser. Measured through-flow velocities are reported for ten quasi-orthogonal survey planes at locations ranging from 1% to 99% of main blade chord. Measured through-flow velocities are compared to those predicted by a 3-D viscous steady flow analysis (Dawes) code. The measurements show the development and progression through the impeller and vaneless diffuser of a through-flow velocity deficit which results from the tip clearance flow and accumulation of low momentum fluid centrifuged from the blade and hub surfaces. Flow traces from the CFD analysis show the origin of this deficit which begins to grow in the inlet region of the impeller where it is first detected near the suction surface side of the passage. It then moves toward the pressure side of the channel, due to the movement of tip clearance flow across the impeller passage, where it is cut by the splitter blade leading edge. As blade loading increases toward the rear of the channel the deficit region is driven back toward the suction surface by the cross-passage pressure gradient. There is no evidence of a large wake region that might result from flow separation and the impeller efficiency is relatively high. The flow field in this impeller is quite similar to that documented previously by NASA Lewis in a large low-speed backswept impeller

X-ray Raman scattering study of aligned polyfluorene

We present a non-resonant inelastic x-ray scattering study at the carbon K-edge on aligned poly[9,9-bis(2-ethylhexyl)-fluorene-2,7-diyl] and show that the x-ray Raman scattering technique can be used as a practical alternative to x-ray absorption measurements. We demonstrate that this novel method can be applied to studies on aligned $\pi$-conjugated polymers complementing diffraction and optical studies. Combining the experimental data and a very recently proposed theoretical scheme we demonstrate a unique property of x-ray Raman scattering by performing the symmetry decomposition on the density of unoccupied electronic states into $s$- and $p$-type symmetry contributions.Comment: 19 pages, 8 figure
