description: Agroforestry-based biofuel production has recently been proposed as a rural development strategy in the South. However, there exists a complete lack of empirical evidence on farmer adoption rates and determinants for these novel systems. This study describes adoption rates of oilseed tree mixtures on smallholder farms in Hassan district, South India, and quantifies how these rates are determined by a biofuel extension program (BP) and farm(er) characteristics. This is done through a set of regression-based analyses, addressing various forms of selection bias. The findings reveal that although 60% of the farmers cultivate oilseed trees, oilseed collection rates are generally low (13%), and the adoption of both practices is driven by different determinants. More specifically, BP activities are found to stimulate tree cultivation and therefore agroforestry establishment, but not seed collection and biofuel production. This calls for a better understanding of adoption profitability in function of the opportunity costs of land, labour and capital involved, and conditional on these results for intensifying BP activities and value chain development.

description: In the present paper, a new three-scale asymptotic homogenization method is proposed to study the electrical behavior of the cardiac tissue structure with multiple heterogeneities at two different levels. The first level is associated with the mesoscopic structure such that the cardiac tissue is composed of extracellular and intracellular domains. The second level is associated with the microscopic structure in such a way the intracellular medium can only be viewed as a periodical layout of unit cells (mitochondria). Then, we define two kinds of local cells that are obtained by upscaling methods. The homogenization method is based on a power series expansion which allows determining the macroscopic (homogenized) bidomain model from the microscopic bidomain problem at each structural level. First, we use the two-scale asymptotic expansion to homogenize the extracellular problem. Then, we apply a three-scale asymptotic expansion in the intracellular problem to obtain its homogenized equation at two levels. The first upscaling level of the intracellular structure yields the mesoscopic equation and the second step of the homogenization leads to obtain the intracellular homogenized equation. Both the mesoscopic and microscopic information is obtained by homogenization to capture local characteristics inside the cardiac tissue structure. Finally, we obtain the macroscopic bidomain model and the heart domain coincides with the intracellular medium and extracellular one, which are two inter-penetrating and superimposed continua connected at each point by the cardiac cellular membrane. The interest of the proposed method comes from the fact that it combines microscopic and mesoscopic characteristics to obtain a macroscopic description of the electrical behavior of the heart.

description: Smallholder farmers which contribute the majority of food production in Africa are in the frontline of the impacts of El Ni o and climate change related risks. The ecosystems on which they rely are increasingly degraded and their access to suitable agricultural land and water resources is declining. In 2015/16, the African agriculture sector was ravaged by drought that has devastated crop yields, scorched grazing land and undermined the resilience of the production systems and livelihoods. Rising food prices reduced real income, forced the poor to sell their assets, decrease food consumption, and further create poverty traps. By the end of 2015, an estimated 60 million people across sub-Saharan Africa didn t have enough to eat. Since there is convincing scientific evidence that the 2015/16 El Ni o was not the first and will not be the last and will obviously result in recurrent disasters in Africa, there is compelling need for the continent to learn from past and prevent similar disasters and strengthen response and recovery efforts. This paper examines response strategies proposed by African countries to build their resilience and explore the appropriate preventative and risk reduction measures and enhance knowledge on effective response and recovery policies and strategies.

description: Using ideas underlying the flavour-blind "Nijmegen Unitarised Meson Model" we try to understand on the basis of a system of Schroedinger equations with one meson-meson and one (spinless) quark-antiquark channel coupled by a simple delta-shell transition potential the formation of (e.g. scalar) meson-meson scattering singularities in the complex momentum and energy plane. Surprisingly we are able to describe without direct meson-meson interaction and without any need for glueballs the whole known scalar meson spectrum. "Light" scalar mesons (e.g. f0(600), kappa(800), f0(980), a0(985), D*0(2290), ...) are identified to belong to the spectrum of the transition potential, while "heavy" scalars (e.g. f0(1370), K*0(1430), f0(1500), f0(1710), a0(1450), D*0(2621) (?), D*0(2825) (?), D*sJ(2928) (?), ...) are related to the confinement spectrum. Due to the particular value of the charm-strange reduced quark mass level-(anti)crossing in the complex momentum plane occurs which relates the BABAR state Ds(2317) to the bare groundstate of the confinement spectrum, while the respective groundstate of the transition potential ends up as D*sJ(2782) (?). We conclude with a short comment on (our) recent progress in the consistent quantum field theoretical effective description of resonances within a Lagrangian framework.

description: Urban agriculture (UA) is regarded as an emerging tool and strategy for sustainable urban development as it addresses a wide array of objectives, such as climate change adaptation, social equality, food security or the restauration of environmental and living conditions. This is particularly important in the case of rapidly growing cities and metropolitan regions of developing and transition countries. Therefore it gains increasing attention among the academic and planning community. We have carried out a survey among 120 gardeners in residential neighbourhoods of the city of Pune (India). We investigated prevailing UA cultivation practices, socio-economic situations, motivation, knowledge and networking of individual household and external framework conditions to analyse the contributions to the environmental, economic and socio-cultural dimensions of urban sustainability. An analytical framework using composite indicators with index values was applied to enable comparability between the two UA types of terrace / rooftop and backyard / kitchen gardens. Our results show that both types contribute differently to urban sustainability at indicator level, but rather similarly at the aggregated level of the sustainability dimension. Sustainability benefits can be expected for the environmental and socio-cultural side, especially for urban biodiversity conservation and aesthetic green urban spaces, but less for economic contributions. Acknowledgement : The authors would like to thank FLOW social sciences research organization for their kind support to conduct the survey among urban gardeners.

description: International migration is an important source of employment and remittances for households in the developing world. In a male-dominated international migration system, females are more likely to head households after the exit of a migrant. In this study, we decompose impacts of international migration into effects attributable to a change in the gender of the household head and effects attributable to other mechanisms. We use an unbalanced panel dataset collected over fourteen years from 2000-2014 in Bangladesh, where international migrants are almost all men. Combining instrumental variable estimation with causal mediation methods, we find that sending an international migrant reduces household participation in crop farming, livestock production, and non-farm businesses at the intensive and extensive margins. However, the average impacts of changes in the gender of the household head due to migration show an opposite effect. We find similar results for input expenditure, capital stock, and time allocation in farming, livestock, and business activities as well. Results show that migration increases household expenditures in food and non-food items, but the newly formed female-headed households induced through migration spend less on food and non-food items and invest more on productive activities.

description: In the classical probability in continuous random variables there is no distinguishing between the probability involving strict inequality and non strict inequality. Moreover a probability involves equality collapse to zero without distinguishing among the values that we would like that the random variable will have for comparison. This work presents Soft Probability by incorporating of Soft Numbers into probability theory. Soft Numbers are set of new numbers that are linear combinations of multiples of ones and multiples of zeros. In this work, we develop a probability involving equality as a soft zero multiple of a probability density function.

description: A detailed study of event by event fluctuation of maximum particle density of the produced particles in narrow pseudo-rapidity interval in terms of the scaled variance ω has been carried out for 16O-AgBr, 28Si-AgBr and 32S-AgBr interactions at an incident momentum of 4.5 AGeV/c. For all the interactions the values of scaled variance are found to be greater than zero indicating the presence of strong event by event fluctuation of maximum particle density values in the multiparticle production process. The event by event fluctuations are found to decrease with the increase of pseudo-rapidity interval. Experimental analysis has been compared with the results obtained from the analysis of events simulated by the Ultra Relativistic Quantum Molecular Dynamics (UrQMD) model. UrQMD model could not replicate the experimental results.

description: Agriculture contributes to the production of a large range of externalities. Their valuation is a critical issue for the design of agro-environmental policies. Hedonic pricing method allows for such valuation using house prices and attributes. However, several endogenous biases affect the estimation. Some of these biases are due to spatial effects, which arise when observations are spatially correlated. The objective of the paper is to apply latest developments of spatial econometrics on a hedonic model to estimate the value of agricultural externalities from Brittany (France). We focused especially on externalities from breeding. We distinguish between direct and spatially indirect impacts of nitrogen pollution, but also on green algae presence, i.e. a nitrogen-related pollution arising on Breton seacoasts for years. Using a database of 8,075 transactions from 2010 to 2012, we run several linear and spatial hedonic models. A Spatial Durbin Error Model (SDEM) is selected as the best model. Our estimations reveal that swine and poultry breedings reduce house prices while cattle breeding has almost no impact on house prices. We highlight that the pollution from swine and poultry overlaps from the municipality where the production occurs. The green algae pollution of the closest beach decreases houses prices by 13.5%.

description: Subsurface flow problems usually involve some degree of uncertainty. Consequently, uncertainty quantification is commonly necessary for subsurface flow prediction. In this work, we propose a methodology for efficient uncertainty quantification for dynamic subsurface flow with a surrogate constructed by the Theory-guided Neural Network (TgNN). The TgNN here is specially designed for problems with stochastic parameters. In the TgNN, stochastic parameters, time and location comprise the input of the neural network, while the quantity of interest is the output. The neural network is trained with available simulation data, while being simultaneously guided by theory (e.g., the governing equation, boundary conditions, initial conditions, etc.) of the underlying problem. The trained neural network can predict solutions of subsurface flow problems with new stochastic parameters. With the TgNN surrogate, the Monte Carlo (MC) method can be efficiently implemented for uncertainty quantification. The proposed methodology is evaluated with two-dimensional dynamic saturated flow problems in porous medium. Numerical results show that the TgNN based surrogate can significantly improve the efficiency of uncertainty quantification tasks compared with simulation based implementation. Further investigations regarding stochastic fields with smaller correlation length, larger variance, changing boundary values and out-of-distribution variances are performed, and satisfactory results are obtained.

description: We present a hybrid quantum-classical simulation of charge-polaron transport in conjugated polymers. The charge, which couples to the angular rotations of the monomers, is modeled via the time-dependent Schr\"odinger equation, while the monomers are treated classically via the Ehrenfest equations of motion. In addition, the system is thermalized by assuming that the monomers are subject to Brownian fluctuations modeled by the Langevin equation. Charge coupling to the monomer rotations localizes the particle into a Landau polaron, while the thermal fluctuations of the monomers causes polaron dynamics. The emergent low-energy scale of the model is the polaron reorganization energy, $E_r$, and thus $T_r = E_r/k_B$ is a convenient scale for the low-temperature dynamics. We investigate two types of dynamics -- both relevant for temperatures $T < T_r$. In the lower temperature regime the system remains in the same quasidiabatic state, corresponding to activationless polaron diffusion as the polaron crawls stochastically along the chain. As the temperature is raised, however, there is a cross-over to an additional activated transfer process which corresponds to hopping between diabatic states. We show that these processes exhibit Landau-Zener type dynamics. We note that as our model is general, it equally applies to exciton-polaron (i.e., energy) transport in conjugated polymers, and to charge and exciton polaron transport in quasi one-dimensional molecular stacks.
title: P-glycoprotein transport cycle: 'cross-talk' between multiple binding sites and the catalytic domains
Creators: name: Martin, Catherine Anne
Publisher: name: The Open University
Year: 2001

description: Elucidation of the mechanism by which P-gp can interact with multiple drugs, and harness the energy from hydrolysis of ATP to mediate transbilayer movement of drug, has been the goal of this thesis. Using radioligand binding studies, four distinct binding sites for drug have been identified on P-gp, explaining the molecular basis of its broad ‘substrate’ specificity. Two of the sites have been classified as transport sites and have been assigned the sites of interaction for vinblastine and paclitaxel respectively. A third site identified was capable of binding both drugs that are transported (Hoechst 33342) by P-gp, and those that are modulatory only (XR9576 and XR9051). The fourth binding site has been classified as a modulatory site, and has been assigned to the modulators nicardipine and GF120918. The existence of a negative heterotropic allosteric network between the sites, suggests that P-gp does not simultaneously bind multiple drugs. In order for transport of drug to occur, the drug binding site must undergo ‘re-orientation’, switching from a high to a low affinity conformation. This transition must be associated with ATP hydrolysis, given the ATP dependency of P-gp transport function. Therefore, binding of vinblastine was measured at discrete steps of the catalytic cycle of P-gp, to ascertain when changes are wrought on the drug binding site. Binding of ATP, prior to hydrolysis, triggered a shift in the high affinity site to a single class of low affinity site. The low affinity conformation for the vinblastine binding site persisted immediately post-hydrolysis of nucleotide. Release of Pi from the P-gp.Mg.ADP.Pi complex, fully restored the drug binding site to high affinity once more. This has provided the first evidence to show that the binding of ATP is sufficient to instigate a transport event. Hydrolysis of ATP is most likely necessary to restore the drug binding site to high affinity in order to complete a transport cycle.

description: As the University of British Columbia’s (UBC) food system emits over 29,000 tonnes of CO₂ every year, UBC’s Climate Action Plan 2030 (CAP 2030) has set a goal of reducing campus food system greenhouse gas (GHG) emissions by 50% before 2030 to improve campus sustainability (Campus and Community Planning, 2021). UBC can pursue food system sustainability through the use of food certifications, which help to provide transparency of the sustainability of food items. On top of improving campus sustainability, UBC’s interest in certifications may help influence other food suppliers and producers to look into food certifications as a method for sustainable food procurement due to their large purchasing power. The four core principles that this project aims to address are reducing GHGs, enhancing biodiversity, ensuring food justice, and promoting food sovereignty. Such principles can help UBC Food Services (UBCFS) further develop a Climate-Friendly Food System (CFFS) Procurement Strategy. The main objectives of this project were: (1) conducting a literature on different food certifications systems and their impacts on climate, biodiversity, food justice, and food sovereignty, (2) finding promising practices other institutions are including in their sustainable procurement policies that UBC can adopt and implement, (3) consulting local food system stakeholders to gain different viewpoints on food certifications, and (4) comparing and analyzing various food certifications to determine how each one could impact UBCFS’s sustainable procurement strategy for five core food categories (coffee and tea, produce, protein, dairy, and bread and baked goods).

description: The pressure induced quantum phase transition of the weakly itinerant ferromagnet MnSi is studied using zero-field $^{29}Si$ NMR spectroscopy and relaxation. Below $P^*\approx 1.2GPa$, the intensity of the signal and the nuclear spin-lattice relaxation is independent of pressure, even though the amplitude of the magnetization drops by 20% from the ambient pressure amplitude. For $P>P^*$, the decreasing intensity within the experimentally detectable bandwidth signals the onset of an inhomogeneous phase that persists to the highest pressure measured, $P\ge 1.75GPa$, which is well beyond the known critical pressure $P_c=1.46GPa$. Implications for the non-Fermi Liquid behavior observed for $P>P_c$ are discussed.

title: The effect of dietary protein source on the metabolism and performance of ewes in late pregnancy and early lactation
Creators: name: Handford, David
Publisher: name: The Open University
Year: 2001

description: Three experiments were carried out to investigate the effects of dietary protein source on the metabolism and performance of straw fed, twin-bearing ewes in late pregnancy and early lactation. In the first experiment, 72 ewes were fed concentrate diets which contained either fishmeal or formaldehyde treated soya-bean meal. The concentrate was either fed alone, or at a reduced rate with feedblocks ad libitum in a two by two factorial design. Ewes fed fishmeal lost more condition after parturition and had lambs which grew quicker than ewes fed treated soya-bean meal (P<0.05). Ewes offered feedblocks produced colostrum with a higher immunoglobulin G (IgG) concentration at birth, had lambs with a higher litter weight than those fed concentrate alone (P<0.05). In the second experiment, 60 ewes were fed concentrates containing either untreated or formaldehyde treated rapeseed meal or field beans in a two by two factorial design with an additional control diet containing fishmeal. Ewes fed fishmeal had a higherpre partum condition score gain and had lambs which grew slower with a lower litter weight at 28 days than ewes fed all other diets. Ewes fed rapeseed meal had a higher total colostrum yield at birth than ewes fed field beans (P<0.05). Ewes fed formaldehyde treated protein sources had a reduced yield of total milk, protein, solids not fat and lactose at 21 days post partum than ewes fed untreated protein sources (P<0.05). In the third experiment, 44 ewes were fed concentrate diets containing either fishmeal, untreated soya-bean meal, formaldehyde treated soya-bean meal or formaldehyde treated soya-bean meal with added rumen protected methionine. Ewes fed formaldehyde treated soya-bean meal with added methionine produced colostrum between 12 and 16 hours post partum with a higher fat concentration and a higher yield of fat and crude protein than ewes fed fishmeal (P<0.05). Ewes fed formaldehyde treated soya-bean meal with added methionine had lambs which grew quicker and were heavier at 28 days of age than those fed fishmeal (P<0.05).

description: We analyze theoretically the entanglement between two non-planar and light identical molecules (e.g., pyramidal as $NH_3$) that present inversion doubling due to the internal spatial inversion of their nuclear conformations by tunneling. The peculiarity of this system lies in the simplicity of this type of molecular system in which two near levels can be connected by allowed electric dipole transition with considerable value of the dipole moment transition and negligible spontaneous emission because the transition is in the microwave or far-infrared range. These properties give place to entanglement states oscillating by free evolution with frequency determined by the dipole-dipole interaction and negligible spontaneous decay, which allows to consider an efficient quantum Zeno effect by frequent measurements of one of the entangled states. If the molecules are initially both in the upper (or lower) eigenstate, the system evolves under an external radiation field, which can induce oscillations of the generated entangled states, with frequency of the order of the Rabi frequency of the field. For a certain detuning, a symmetric entangled state, eigenstate of the collective system can be populated, and given its negligible spontaneous emission, could be maintained for a time only limited by external decoherence processes which could be minimized. Although the data used are those of the $NH_3$ molecule, other molecules could present the same advantageous features.

title: Role of monocytes in the pathogenesis of HIV-1 infection

Publisher: name: The Open University

description: Peripheral blood monocytes and tissue macrophages play critical roles in both the natural history and the pathogenesis of HIV-1 infection. This thesis mainly focused on the study of a potential defensive role of macrophages in HIV-1 infection.
HIV-1 expression in monocyte-derived macrophages (MDM) infected in vitro is known to be inhibited by lypopolysaccharide (LPS), the main component of the bacterial cell wall. However, the mechanisms are not completely understood. We show herein that LPS protects primary macrophages from infection by CCR5-dependent HIV-1 isolates. Inhibition was largely mediated by the release of the C-C chemokines RANTES, MIP-1ɑ and MTP-1ß. Indeed, (a) addition of LPS to MDM resulted in the vigorous production of RANTES, MDMa and MIP-1ß; (b) high levels of CCR5, the C-C chemokine receptor, were expressed by MDM at the time of infection; (c) antibody- mediated depletion of RANTES, MIP-1ɑ and MIP-1ß blocked HIV-1 infection as effectively as LPS itself.
 CXCR4 mediates the entry of syncytia-inducing strains, both primary and T cell line-adapted. The ability of SI HIV-1 isolates to infect primary human macrophages has been disputed. Here, we report that CXCR4 expression on human MDM was variable but consistently significant. Primary CXCR4- dependent HIV-1 strains infected MDM productively and were specifically blocked by SDF 1. By contrast MDM supported the entry but not the replication of CXCR4-dependent TCLA HIV strains. Thus, monocyte/macrophages support the entry and replication not only of CCRS-dependent, but also of CXCR4-dependent primary HIV-1 isolates.
 Because CXCR4 is a functional coreceptor for HIV-1 infection of human macrophages, we investigated whether LPS also affects the replication of CXCR4-dependent HIV-1 isolates. Our results show that LPS inhibits the replication of X4 HIV-1 isolates in MDM through the release of novel soluble suppressive factor(s) that are as of yet uncharacterized.

description: In recent decades, New World has increased their wine export to European markets and became considerable market players. Therefore, it is important to investigate whether the major New World wine producers are able to exploit its market power at the Old World s markets. The paper investigates the pricing behavior of major New World wine exporters in their most significant European destination markets using a pricing-to-market (PTM) model in respect of asymmetric effect of exchange rate changes between 2000 and 2016. First, the results suggest that Chile was able to apply price discrimination across Danish, German, Dutch, the UK wine markets. Second, South Africa set their prices in Belgian, Dutch and Swedish markets while the USA discriminated their wine prices in Denmark and Sweden. In contrast, this advantage was not observable in a case of Argentina, Australia. Third, the local-currency price stability was explored in case of Belgium, the Czech Republic and France (Chilean wine prices), Denmark, Germany (South African wine prices) and Germany, UK (US wine prices). Furthermore, the analysis of the asymmetric effects of exchange rates suggests that depreciation of the exporter s currency relative to the Euro had not a significant impact on wine import prices.

Moving towards a better future for your children? The impact of maternal migration on child nutrition in Tanzania

description: Research on the impact of internal migration has focused on (monetary) outcomes for the migrants themselves. Yet, migrant parents may be able to not only improve their own welfare, but also enhance the well-being of their children. As such, population movements could affect current living standards as well as the intergenerational transmission of poverty and rural transformation. The crucially important question of how parental migration affects children, however, remains largely unanswered with existing studies based upon cross-sectional designs that do not allow us to disentangle the impact of migration from selection. Using panel data tracking migrants between 1991 and 2010, this paper studies how maternal migration affects child nutrition. We restrict the comparison to children of mothers originating from the same family, effectively addressing concerns that heterogeneity across migrant and non-migrant families may distort the results. We find evidence of a growth advantage for children of mothers who moved out of their villages in Kagera. Maternal migration is associated with improved weight-for-age and lower rates of underweight. Moreover, children of rural-urban migrant mothers have higher height-for-age z-scores and lower stunting rates. These findings therefore suggest that by relocating, mothers were able to improve their children s long-term food security and health. Acknowledgement :

description: We consider the impact of cosmological $B-L$ constraints on supersymmetric standard models with bilinear breaking of R-parity. In order to avoid erasing any primordial baryon or lepton asymmetry above the electroweak scale, $B-L$ violation for at least one generation should be sufficiently small. Working in the context of models with non--universal soft supersymmetry breaking masses, we show how the above cosmological constraint can be satisfied while simultaneously providing a neutrino mass matrix required by current data.

description: Aims: We explore the long-term evolution of young protoplanetary disks with different approaches to computing the thermal structure determined by various cooling and heating processes in the disk and its surroundings. Methods: Numerical hydrodynamics simulations in the thin-disk limit were complemented with three thermal evolution schemes: a simplified $β$-cooling approach with and without irradiation, in which the rate of disk cooling is proportional to the local dynamical time, a fiducial model with equal dust and gas temperatures calculated taking viscous heating, irradiation, and radiative cooling into account, and also a more sophisticated approach allowing decoupled dust and gas temperatures. Results: We found that the gas temperature may significantly exceed that of dust in the outer regions of young disks thanks to additional compressional heating caused by the infalling envelope material in the early stages of disk evolution and slow collisional exchange of energy between gas and dust in low-density disk regions. The outer envelope however shows an inverse trend with the gas temperatures dropping below that of dust. The global disk evolution is only weakly sensitive to temperature decoupling. Nevertheless, separate dust and gas temperatures may affect the chemical composition, dust evolution, and disk mass estimates. Constant-$β$ models without stellar and background irradiation fail to reproduce the disk evolution with more sophisticated thermal schemes because of intrinsically variable nature of the $β$-parameter. Constant-$β$ models with irradiation can better match the dynamical and thermal evolution, but the agreement is still incomplete. Conclusions: Models allowing separate dust and gas temperatures are needed when emphasis is placed on the chemical or dust evolution in protoplanetary disks, particularly in sub-solar metallicity environments.

title: The Photochemistry of N-Arylsulfonyl Amino Acids and Peptides
Creators: name: Moore, Sharon Ann
Publisher: name: The Open University
Year: 2001

description: The photochemistry of arylsulfonamides has received continuing interest for the last four decades for three main reasons: 1) arylsulfonamides offer convenient acceptor properties for studying photo-induced electron transfer (PIET.) processes in chromophorically modified peptide models, 2) arylsulfonamides have potential as photoremovable protecting groups in organic synthesis, but this has so far remained largely unrealized, 3) arylsulfonamide pharmaceuticals are generally photolabile and photostability is an important consideration in the development of new drugs.
We have studied a series of p-toluenesulfonyl amino acid derivatives and undertaken comprehensive product analysis to elucidate the photoproducts and identify common pathways of photodegradation. We found that the tosyl a-amino acids formed toluenesulfinic acid as a major photoproduct in conjunction with ammonia, carbon dioxide and a carbonyl compound. Upon changing the carboxylate to an ester or an amide, a Cɑ-H abstraction became the dominant process to give a carbonyl compound, toluenesulfinic acid and ammonia. These were also the major photoproducts with a tosyl ß-amino acid. A mechanism is proposed that involves an initial electron transfer (ET) from the carboxyl function to the sulfonyl moiety to give a biradical intermediate that could react to produce most of the observed products.
Some differences in product distribution were found with different amino acid side-chains, although bulky aliphatic or sulfur containing side-chains produced little variation. A tyrosine derivative underwent side-chain cleavage, implying electron transfer from the side-chain rather than the carboxyl function. Peptide bond cleavages occurred in the majority of amide derivatives, which can also be explained by an electron transfer mechanism. The results showed that S-N cleavage to form the free amino acid moiety occurs in very poor yield due to a complex array of competing photoreactions.
A photoyellowing was seen in many of the amide compounds which may be due to photochromism, a process that is consistent with our photo-induced electron transfer hypothesis.
