Abbas el fassi biography of albert einstein
The nature of Dark Matter (DM) remains one of the greatest puzzles in particle physics and cosmology. While overwhelming observational evidence across galactic and cosmological scales confirms its existence, decades of experiments have only verified its gravitational interaction. Key properties of DM -- such as its spin, mass, non-gravitational interactions, stabilizing symmetry, number of associated states, and mediating particles linking DM to Standard Model interactions -- remain unknown.
To address these challenges, we propose a systematic classification of DM based on DM and mediator multiplets with different spins and weak group charges. Additionally, we introduce a novel class of models -- Fermionic Portal Vector Dark Matter (FPVDM) -- that extends the Standard Model with an SU(2) dark gauge sector. FPVDM offers important implications for direct and indirect detection experiments, relic density, and collider searches
as well as provides the Gravitational Wave signals from specific regions of the parameter space, where the strong first-order phase transition takes place.
Examples of DM models and their signatures will be discussed, alongside prospects for current and future experiments to test them. This talk will argue that a systematic classification of DM models and their signals provides a robust framework for discovering and identifying Dark Matter in the near future.

Creating Biography Webs to Investigate Individuals' Historical Contexts
ERIC Educational Resources Information Center
Fertig, Gary; Silverman, Rick
Biographies, which are popular among young people, can stimulate interest in the past when students investigate the historical contexts in which individuals lived. Creating biography webs offers students structured opportunities to investigate how other people and groups influenced the personal development of specific individuals (NCSS Strands II,…
Deterritorializing Collective Biography
ERIC Educational Resources Information Center
Gannon, Susanne; Walsh, Susan; Byers, Michele; Rajiva, Mythili
This paper proposes a new move in the methodological practice of collective biography, by provoking a shift beyond any remnant attachment to the speaking/writing subject towards her dispersal and displacement via textual interventions that stress multivocality. These include the use of photographs, drama, and various genres of writing. Using a…
Definitions of Feminist and Sexist Biographies of Women.
ERIC Educational Resources Information Center
Bloom, Lynn Z.
This paper is concerned with determining the influences of biographers' gender on the content of biographies of women. The following questions are addressed: Do some treatments of subjects produce feminist or sexist biographies? What are the principal characteristics of both forms? Which, if any, of these features combine to result in identifiable…
Field Balancing and Harmonic Vibration Suppression in Rigid AMB-Rotor Systems with Rotor Imbalances and Sensor Runout.

Xu, Xiangbo; Chen, Shao
Harmonic vibrations of high-speed rotors in momentum exchange devices are primary disturbances for attitude control of spacecraft. Active magnetic bearings (AMBs), offering the ability to control the AMB-rotor dynamic behaviors, are preferred in high-precision and micro-vibration applications, such as high-solution Earth observation satellites. However,
In anticipation of the upcoming International Women's Day on 8 March, we bring you the fascinating story of the first-ever woman taxi-driver in Fez.
Fez resident Vanessa Bonnin tracked down the intrepid taxi-driver, Lamiae El Oubeidi. This is Vanessa's report:
Lamiae is a formidable woman. In the face of opposition from her family, her husband, the government and society, she held firm to her ideals and in doing so broke new ground for women in Morocco. How did she do this? By becoming the first female taxi driver in Fez and the second woman to drive a cab in Morocco.
&#;I wanted to be the first woman in the history of Fez to take this job, so that people would be aware of how important it is for women to take such challenges,&#; she said.
&#;I want to be an example to other women, so we can [eventually] see women driving taxis, buses or even working in construction.&#;
A year-old mother of two, Lamiae has diplomas in science, IT and accounting, but when she lost her teaching job she needed to find work to help support her children. She chose driving a taxi because she wanted to be in control of her working hours.
&#;This job allows me to manage my time around all my different commitments and helps me make sure I spend enough time with my kids,&#; she said. Her husband was already a taxi driver and she firstly had to convince him that she should contribute to the family income in the same way.
&#;It took me time to change his way of thinking, I&#;ve been pretty diplomatic explaining to him that his income isn&#;t enough, we have kids and expenses&#;so I eventually managed to convince him,&#; she explained.
&#;But other men tell my husband &#;You&#;re not a man! You let your wife go out and do such a job?&#; This is difficult for him.&#;
The second difficulty was her parents. Born to a well-bred, conservative, Fassi family Lamiae had a hard time persuading them that she would not be in danger as a female taxi driver.
