Giffoni Film Festival: How to Morph a Rural Area in an Innovation Cluster in the Digital Arts Production
No full textWith Giffoni Film Festival (GFF) at the pinnacle of its growth, founder Claudio Gubitosi is
imagining how to cultivate the GFF brand to the benefit of the local community. His strategic
vision for GFF as an opportunity to build a local cluster of startups will require a more active
involvement from the GFF organization on the business side and possibly a new governance
format for the festival. The future of GFF revolves around the new Multimedia Valley Campus
where the European Community and Campania regional government has injected more than EUR
38 million for new facilities, with a vision to brand and expand GFF from a 10-day event to a
regional node of a future innovation
Assisted Oocyte Activation Method (Ca ACTIVATION) Improves Fertilization in Patients with Recurrent Fertilization Failure
No full textAbstract: Total fertilization failure (TFF) happens in 1–3% of total intracytoplasmic sperm injection (ICSI) cycles and may reoccur in sequent cycles. Regardless the high success rate with the applying of intracytoplasmic sperm injection (ICSI), there's still a little number of couples who cannot get fertilized eggs after using ICSI. Six couples experiencing recurrent TFF or low fertilization rate (<10%) after ICSI were recorded in this study. Compared with the regular ICSI group and the conventional ICSI-AOA group, the new AOA method using calcium ionophore, can seriously increase the fertilization rate from less than 10% up to approximately 50% in most cases. The normal distribution of sperm-related oocyte activation factor phospholipase C zeta (PLCz1) in the sperms of the cases indicated the absence of an aberrant Ca signaling activation.
AOA method using calcium (Calcium ionophore A23187) was able to effectively improve the fertilization rate in the majority of patients suffering from TFF. This AOA method had a potential therapeutic effect on those couples experiencing TFF, even after intracytoplasmic sperm injection (ICSI), which may overcome the severe fertilization deficiencies in patients with a repeated low fertilization or TFF.
Keywords: total fertilization failure, Calcium ionophore A23187, fertilization, assisted oocyte activation.

Data Communication through Distribution Network for Smart Grid Applications
No full textA Master of Science thesis in Electrical Engineering by Youssef El Haj entitled, "Data Communication through Distribution Network for Smart Grid Applications," submitted in May 2014. Thesis advisor is Dr. Lutfi Albasha and thesis co-advisor is Dr. Ayman Hassan El-Hag. Available are both soft and hard copies of the thesis.This work investigates a novel solution for overcoming excessive signal attenuation in distribution transformers for power line communication (PLC) applications in smart grids. The proposed solution avoids classical hardware bypassing and does not require sophisticated modulation schemes like Orthogonal Frequency Division Multiplexing (OFDM). It explores the resonance that occurs in transformer windings at the kHz range to transmit the communication signal. The transformer is modeled as a network of resistors, inductors and capacitors. This results in several resonance frequencies in the kHz and MHz ranges that can be used to pass the communication signal. Several methods can be used to obtain the frequency response of distribution transformers. In this work, the Frequency Response Analysis (FRA) technique is implemented. This technique measures the amplitude and phase response due to the application of a swept sinusoid at one terminal of the transformer winding. FRA measurement of a 20kVA (220/20kV) transformer indicated that there is a resonance at 490 kHz with a gain of 2 V/V and a bandwidth of 40 kHz. The captured frequency response is then modelled as a communication channel. Then digital modulated Binary Phase Shift Keying (BPSK) signals (at resonance and nonresonance frequencies) are transmitted through the modeled transformer. Sending data at 490 kHz within the 40 kHz bandwidth resulted in Bit Error Rate (BER) values that appear better than the Additive White Gaussian Noise (AWGN) channel because of the associated gain in the transformer. In addition, the simulation verified that sending data at non-resonance frequencies or outside the resonance bandwidth resulted in poor BER. The final issue investigated in this work is the effect of distribution cables from the utility substation up to the customers' distribution transformers. The simulation confirmed that the cable at high frequency acts as an attenuator with a value of attenuation that depends on the cable length. The BER was calculated for variable cable lengths cascaded with the transformer. By sending a BPSK signal at resonance with a bandwidth of 20 kHz, the BER was zero for cases where the attenuation was less than 40 dB. The research results showed that sending data at resonance frequencies has the potential to be an effective method for improving data communication using PLC for smart grid applications.College of EngineeringDepartment of Electrical EngineeringMaster of Science in Electrical Engineering (MSEE
Experiencing the armed struggle : the Soweto generation and after
No full textIncludes bibliographical references (p. 354-369).This study explores the experiences of the rank-and-file soldiers of Umkhonto we Sizwe and the Azanian People's Liberation Anny. Extensive interviews by the author and other researchers reveal the voices of the soldiers themselves. The African National Congress and Pan African Congress archives at the University of the Western Cape and the University of Fort Hare supplement and verify these oral testimonies, as do some published sources. Most previously published materials about the armed struggle against apartheid have already focused on diplomacy, strategy and tactics, operations, leadership, and human rights abuses to the neglect of the soldiers' actual experiences. This study complements these with significant new oral history materials from the Soweto generation of soldiers and their successors. When dealing with MK, many authors have documented issues of the camp structure in Angola, and operations inside South Africa, so much of this detail is only addressed briefly, leaving space to explore the soldiers' experiences. In the case of APLA, very little has been written on its history, and more detail is provided on these subjects. This study therefore deals with the soldiers' politicisation and motivation for joining the armed struggle, their experiences in leaving South Africa and training in exile, the crises in exile which limited their effectiveness for a time, their return to fight in South Africa, and their difficulties in the "new" South Africa. These materials reveal that vast problems remain facing these veterans of the struggle against apartheid, and that they have the potential, if properly supported and employed, to contribute substantially to the development of present day South Africa. Conversely, if their neglect continues, they also have the potential to bring vast harm to the country. Further use of the investigative tools of oral history, especially if extended to the former soldiers' vernacular languages, is necessary to augment the history of South Africa, and these soldiers' contributions
Conservation in an Islamic context a case study of Makkah
No full textThe Holy Qu’ rān contains many injunctions for Muslims to respect and conserve the natural environment but few address the built environment. Habitat at the time of the Prophet (PBOH) was in the vernacular and relatively impermanent. The first habitat was the cave, the second the tent and then simple flat roofed buildings of post and lintel construction made of mud and rubble. Later buildings were not indigenous but reflected the architectural styles and techniques of Muslim pilgrims from beyond the Arabian Peninsula. Permanent exotic buildings were later erected as reminders of holy places and events. This work advances a case to restore and preserve historic and religious sites in Makkah, Saudi Arabia. Makkah is the destination for millions of Muslim pilgrims who annually pay homage to Allah during the occasions of Hajj, Ramadan and Umra. The tranquillity and peaceful ambience that one associates with the holiest of Islamic experiences have, over the years, given way to jostling crowds of people who must be expediently housed, fed, transported, and protected. Due to the lack of planning and the insensitive but profitable development of the city, Makkah is in grave danger of becoming a bustling metropolis instead of a sanctuary where pilgrims gather to perform their religious rites and reaffirm their dedication to Allah. The author calls for professional planning and international cooperation to guide future development for this expanding and sensitive area. The author's ideas are grounded in practical and aesthetic study, therefore, the political, environmental and economic issues are examined in relationship to religious, historic and artistic values. The author makes proposals for a future Makkah that would provide pilgrims with the physical comforts, security, and serene environment they deserve—without destroying the city they came to visit. The author discusses preservation and conservation in the western world and the need for their acceptance in Muslim countries, the former being an aesthetic and intellectual concept sustained by law and the latter being the prescribed free expression of the individual unhindered by material considerations. Both worlds are rapidly being overwhelmed by materialism, but body, mind and spirit combine in making us aware of our surroundings and the way in what we see around us has come into being
