Challenges of water and sanitation service co-production in the global South
No full textCo-production of water and sanitation services, especially in the global South, implies that recipients of a service play a fundamental role in managing water resources. In the context of citizen–government synergies, service recipients are more than consumers, and (co)-production alters their involvement in the service production process, with respect to their relationships with both the natural resources and the delivery process. Our hypothesis is that a meaningful understanding of co-production for water and sanitation services is only possible through an interdisciplinary approach that takes into account natural and social dimensions. The objective is to develop a possible new conceptualization of service co-production that can foster a renewed citizenship while taking into account the risks of urban fragmentation
A theoretical study of the effect of electron delocalization on electron transfer reactions in small organic molecules
No full textDissertation (MSc (Chemistry))--University of Pretoria, 2022.The ionization potential and electron attachment energy are fundamental properties of molecules and is core to a range of physical processes such as those in photovoltaics, electrochemistry, spectroscopy, etc. Ionization energies are therefore properties worthwhile to have delicate control over for the purpose of finetuning molecules for specific goals. Here we have brought it to light that there are relationships between ionization energies and electron populations of small organic electron donors and acceptors. Electron population data was gathered with FALDI. For the electron donors Ph-XR2, where X = N or P and R = H, Me, Et or Pr, it was found that as the delocalization between phenyl and substituted group increases, the ionization potential decreases (electron removal becomes easier). For the acceptors Ph-RNO, where R = none, CH2, C2H4, or C2H2, as delocalization between phenyl and substituent increases electron attachment energy decreases further (electron attachment became more spontaneous). Furthermore, for these acceptor molecules, as phenyl ring electron population increases, electron attachment becomes less spontaneous. For acceptor molecules Ph-X, where X = F, Cl or Br, as the phenyl electron population increased, electron attachment became easier. All these relationships were near perfectly linear. This is the first time, to our knowledge, that such a link is found between ionization energies and electron populations. Also, physical phenomena such as conjugation, hyperconjugation, lone-pair electron resonance and Bent’s rule could be recovered and quantified with FALDI. Lastly, four donor-acceptor interfaces were built from donors Ph-NH2 and Ph-NPr2 and from acceptors Ph-NO and Ph-C2H4NO, to simulate the heterojunction in an organic photovoltaics. Marcus theory was implemented to successfully calculate forward (in presence and absence of light) and reverse charge transfer rates which are some of the factors that influence the efficiency of a solar cell. The quickest rate was two orders of magnitude faster than second best at 8.40E+13 e-/s for interface [Ph-NH2–Ph-C2H4NO]. The rates were decomposed into the coupling potential and thermodynamic driving force to find the origin of such a vast difference. This revealed that a greater transition dipole moment (on which the coupling potential is dependent) of the electronic transition caused this interface to completely excel in charge transfer relative to the others. FALDI analyses were performed on the interfaces to attempt to complete the chain between the chemistry of the molecules and the rate constants – in this case transition moment, therefore. There is good indication that the transition moment is linked to the FALDI terms, suggesting that all information about the transition moment is contained in them. FALDI therefore shows great potential for a new way of calculating the transition moment.ChemistryMSc (Chemistry)Unrestricte

Evaluation of the highest temperature WMO region VI Europe (continental): 48.8°C, Siracusa Sicilia, Italy on August 11, 2021
No full textA maximum temperature of 48.8°C (119.8°F) was purportedly recorded for the automated station in Siracusa (Syracuse) Contrada Monasteri, on the island of Sicilia (Sicily) Italy on August 11, 2021. A World Meteorological Organization (WMO) ad hoc evaluation committee was assembled to assess the possibility that the Sicilia temperature was the highest recorded temperature in WMO Region VI (continental only). After a detailed review of the site considerations and of the regional synoptic weather conditions, combined with detailed sensor testing and calibration by the Istituto Nazionale di Ricerca Metrologica (INRiM), the WMO evaluation committee concluded (and the Rapporteur accepted) that (1) on August 11, 2021 the high temperature recorded for the automated station in Siracusa C. da Monasteri, did reach a maximum value of 48.8°C (119.8°F), (2) that temperature is recommended to be listed as the WMO official “highest recorded temperature in WMO Region VI (continental only)” and (3) although, as the INRiM testing established, the recorded value of 48.8°C is actually an underestimate of the temperature, the committee recommend that the recorded (likely conservative) value of 48.8°C be the value listed in the Archive. An arbitrated archive of current weather and climate extremes is one means of ensuring that we have the best possible data for climate change analysis and public dissemination
Real time monitoring of the radiation environment on the ISS with AMS-02
No full textThe International Space Station (ISS) is the most frequented place by human activity in space. The atmosphere is thin and the geomagnetic field offers a partial protection from radiation. Since the energetic spectrum of cosmic rays
follows a decreasing power law, even though the highest energy portion is the most dangerous, it is scarcely populated: one of the most dangerous sources of radiation
damage is represented by hadrons in the low end of the energetic spectrum, mainly constituted by Solar Energetic Particles (SEPs). The Alpha Magnetic Spectrometer (AMS-02) is an experiment operating on the ISS since 2011, performing precision measurements of cosmic ray composition and flux. We report on a study to verify if the low latency trigger information of AMS-02 could be used to perform a nowcast and monitoring service of the radiation environment and solar activity outside the ISS. A data-driven confirmation of the capability for real-time identification of SEP events outside of the ISS has been achieved, using an algorithm capable of determining abrupt excesses in the AMS-02 trigger rate with respect to that expected in quiet conditions, simulating real time access to low-latency data directly
from AMS-02

IMPLEMENTATION OF LSB AND PLAYFAIR METHODS TO SECURE TEXT FILES INTO WAV AUDIO FILES
No full textIn the rapidly evolving digital communication era, the demand for information security is escalating. Three main security techniques are required: cryptography, watermarking, and steganography. Despite cryptography and watermarking having detectability weaknesses, steganography emerges as a more reliable choice as it can conceal messages across various media without arousing suspicion. This article discusses the utilization of steganography, particularly the Least Significant Bit (LSB) technique, for embedding messages within audio wave files as the medium. In this research, the author combines steganography with encryption using the Playfair Cipher algorithm to enhance overall data confidentiality. Implementation results demonstrate that the combination of LSB and Playfair methods effectively conceals messages without compromising audio quality. Evaluation of stego quality using PSNR indicates that audio quality remains high after embedding secret messages, with PSNR exceeding 40 dB. Despite successful message extraction during decoding, the message content remains protected and requires decryption to be read. In conclusion, the use of steganography in audio wave files with a combination of Playfair Cipher encryption and LSB methods proves to be an effective approach in preserving privacy and data confidentiality during transmission
