Many photographs of women published in the Iranian press during the Iran-Iraq War emphasized their roles as supportive and mourning mothers and sisters. By contrast, the often gruesome images that depicted women’s deaths in the war proved more difficult to categorize. The difficulty reflected ambivalence towards attaching the label of shahid, or martyr, to dead women’s images. These photographs, whether gruesomely depicting their bodies or portraits taken prior to death, oscillated between evoking shahadat (martyrdom), consistently applied to men, and depicting their deaths merely as national tragedy. The ambiguous approach to gendered depictions of martyrdom reflected attempts by the Iranian press to negotiate women’s roles during the war in newspaper photographs from the newly-established Islamic Republic. However, in the context of the 2009 Green Movement, Neda Agha-Soltan’s widely viewed death revealed a change in the ambiguity of women’s possible martyr status. In this project, I trace the depictions of women as possible martyrs during the Iran-Iraq War and pose it against the visual experiences during the Green Movement. I argue that while earlier representations reflected tenuousness and ambiguity on the part of Iranian periodicals, such as Ettela’at, Jomhuri-e eslami, and Imposed War, as they sought to grapple with the turmoil of war and a still emergent political system, the Iranian press’s clear denial of female martyrdom during the Green Movement side-by-side with reproductions of Agha-Soltan’s death images reflected a shift in the application of shahid. Although the Iranian press rejected her shahid status, agencies like Fars News attached photographs from Neda’s death video to articles thereby presenting an unclear message about Agha-Soltan’s potential for shahadat. This complicated viewing along with the multitude of examples of her “death” images made her agency in the frame possible, unlike women during the war. Agha-Soltan’s death images presented a possible shift in ownership of shahadat from the state-sponsored press’s hands to that of the people. Thus while the official press had solidified its approach to (not) applying the label of martyr to women, it did so at a moment in which it had lost its monopoly over the declaration and depiction of martyrdom. / text

Photodetectors are a kind of semiconductor devices that convert incoming light to an electrical signal. Photodetectors are classified based on their different structure, fabrication technology, applications and different sensitivity. Infrared photodetectors are widely used in many applications such as night vision, thermal cameras, remote temperature sensing, and medical diagnosis etc.   All detectors have material inside that is sensitive to incoming light. It will absorb the photons and, if the incoming photons have enough energy, electrons will be excited to higher energy levels and if these electrons are free to move, under the effect of an external electric field, a photocurrent is generated.   In this project Fourier Transform Infrared (FT-IR) Spectroscopy is used to investigate a new kind of photodiodes that are based on self-assembled semiconductor nanowires (NWs) which are grown directly on the substrate without any epi-layer. The spectrally resolved photocurrent (at different applied biases) and IV curves (in darkness and illumination) for different temperatures have been studied respectively. Polarization effects (at low and high Temperatures) have been investigated.  The experiments are conducted for different samples with high concentration of NWs as well as with lower concentration of NWs in the temperature range from 78 K (-195ºC) to 300 (27ºC). These photodiodes are designed to work in near infrared (NIR) spectral range.   The results show that the NW photodetectors indeed are promising devices with fairly high break down voltage, change of photocurrent spectra with polarized light, low and constant reverse saturation current (Is). The impact of different polarized light on photocurrent spectra has been investigated and an attempt has been made to clarify the observed double peak of InP photocurrent spectrum. Our investigations also include a comparison to a conventional planar InP p-i-n photodetector.

Prophetic reports, constituting the second foundational source of the Islamic Weltanschauung, have been categorised in terms of their authenticity. The current work explores reports occurring in single transmission chains that are corroborated in word or meaning by other similarly narrated reports whose source at the level of Prophet Muhammad's companions could either be the same or different. Rules pertaining to this field have been amalgamated for the first time to simplify their application. Appropriated practical examples have been given to illustrate harmony between theory and praxis. Concentration has been restricted to a corroboration of reports by other transmission chains. An examination of the latter falls outside the scope of this investigation. / Religious Studies and Arabic / M.A. (Islamic Studies)
