Semiochemicals have been widely considered within various integrated pest management (IPM) strategies. In the present work, two sesquiterpenoids, E-β-farnesene and E-β-caryophyllene, were formulated for their related properties as aphid enemy attractants. E-β-farnesene, the alarm pheromone of many aphid species, was also identified as a kairomone of aphid predators (Episyrphus balteatus De Geer (Diptera: Syrphidae)) and parasitoids (Aphidius ervi Haliday (Hymenoptera: Braconidae)). E-β-caryophyllene was identified as a potential component of the aggregation pheromone of the Asian ladybird, Harmonia axyridis Pallas, another aphid predator. The two products were purified from essential oils of Matricaria chamomilla L. (Asteraceae) and Nepeta cataria L. (Lamiaceae) for E-β-farnesene and E-β-caryophyllene, respectively. Natural and biodegradable slow-release formulations were then investigated in order to deliver these molecules on crop fields for a long period of time as biological control devices. Due to their sensitivity to oxidation, both sesquiterpenes needed to be protected from degradation. For this purpose, alginate – hydrophilic matrix with low oxygen permeability – was used as polymer for the formulations: the main objective was to deliver semiochemical substances in the air in a controlled way. Consequently, a careful selection of alginates was realised. Formulated beads showed different structural and encapsulation properties depending on various formulation factors. Alginate formulations were characterized by texturometry and by confocal microscopy in order to observe the distribution of semiochemicals in alginate network. The last step of alginate bead characterisation consisted in studying release rate of semiochemicals in laboratory-controlled conditions by optimised trapping and validated Fast-GC procedures. Finally, the efficiency of formulations as aphid predator (Syrphidae) and parasitoid (A. ervi) attractants was demonstrated by field trapping and olfactometry experiments. [less ▲]

The Tonle Sap Great Lake and the Mekong River in Cambodia have huge floodplain suitable for rice-based farming system and potential water resources for farming. Studies to exploit the flood and the water resources of the lake and the river have not been well conducted yet. Batheay irrigation system is located in the floodplain of the Tonle Sap River and the Mekong River. In this research, the irrigation system is studied as a model site for future development of the floodplain of the Tonle Sap Great Lake and the Mekong River. Batheay reservoir directly receives floodwater from the Mekong. It functions as both a reservoir and a paddy field. In wet season, dike around the Batheay reservoir prevents floodwater from entering the reservoir. Rainy season rice is grown inside the reservoir. After harvesting, gates around the reservoir are opened to receive floodwater. The water is stored for cultivating dry season rice outside the reservoir. In this work, we attempt to study water management of the Batheay irrigation system by analyzing water use pattern in the irrigation system and uncover effectiveness of the system. This study plays a vital role in the study of the Tonle Sap Great Lake system in our future research. [less ▲]

This paper presents two simple cooling coil models. The first part of the paper describes and validates the first one (“reference model”). This model only necessitates 3 parameters, which can be estimated by using commissioning or manufacturer information. The second part of the paper presents and validates the second simple model (“simplified model”). The paper shows how the latter can be built from the reference model, when there is no need to describe what happens on the refrigerant side. This simplified model can be easily integrated in the model of a global HVAC system in order to calculate the cooling coil energy consumption over large time periods. The simplified model is appropriate to decrease the computational time and avoid numerical instabilities. [less ▲]

Focusing on Africa, sun is a renewable resource, free of charge, without any dependency of supply from other countries but implying technologies to transform this resource into electricity. Photovoltaic panels are dedicated to this goal and present several advantages as the free cost of the fuel and no emissions during the production of electricity. These advantages are counterbalanced by the high amount of mineral resources needed, the lifetime of installations, the decreasing yield during operation years and the very limited recycling potential [less ▲]

Herein, we describe the development of an efficient solid-supported methodology for the stereoselective synthesis of two peptides containing (2S,6R)-diaminopimelic acid, (S)-Ala-γ-(R)-Glu-(2S,6R)-A2pm-(R)-Ala 1 and γ-(R)-Glu-(2S,6R)-A2pm 2. The platform consists of a Wang resin anchored by an amino acid chain including allylglycine. By olefin cross metathesis with vinylglycine, unsaturated protected (2S,6R)-A2pm was fixed on solid support. Peptides were achieved by cleavage of cross metathesis products from resin, followed by reduction of double bonds along removing of protecting groups. Furthermore, this efficient solid phase approach will lead to peptide and muropeptide libraries. [less ▲]

Evolution of sensitizing antibodies involved in antibody-dependent cell-mediated cytotoxicity (ADCC), antibody-complement cell lysis and complement-facilitated ADCC was followed in bulls after primary infection by a wild strain of infectious bovine rhinotracheitis virus (bovine herpesvirus 1; BHV-1) and after experimental reactivation of the virus. These antibodies were detected between the 4th and the 7th day after primary infection, reached a maximum level after 2 weeks and rose slightly after reactivation of the virus following dexamethasone treatment. The presence of endogenous complement slightly enhanced the ADCC reaction. [less ▲]

Nowadays, city local governments focus their strategic vision on the development of the urban sustainability. For this, they develop drivers, strategies, structures on green local improvements. To be sustainable, cities reinforce actions and plans on resource management, mobility, climate, building and public spaces. In order to be sustainable and smart, challenges are set to ensure successful implementation of sustainable mobility strategies through the development of appropriate policies, actions, decisions and controls. The development of sustainable mobility strategy requires the involvement of strategic actors, infrastructures, funding and socio-demographic parameters. To ensure this, sustainable mobility strategy has to be strengthen by an efficient management control system and a real measurement of institutional factors’ risk. The development of mobility controls ensures homogeneity between behaviours, decisions, objectives and strategies for mobility issues. In order to make the link between control, strategy and sustainability, new researches propose new frameworks and systems. These frameworks reinforce the strategic contribution of values, rules, monitoring and enhancing awareness and interactions. Based on that, the management control framework of Malmi and Brown is more and more associated with the implementation of sustainable strategies. This paper explores the development of sustainable mobility strategies in two Belgian cities (Namur and Leuven). To analyse how cilty local governments implement, control and develop mobility strategies and plans, this paper refers to Malmi and Brown’s model. The research proposes two hypotheses that set the importance of the integration of an adequate sustainable mobility control system and the institutional factors on the design and the use of mobility strategy control. This paper proposes a new conceptual model to support the development of sustainable mobility strategy. For this, the choice of two Belgian cities is made according to similarities (population size, explicit will to develop sustainable mobility strategy, focus on sustainable transport, initiation period of mobility issues’ implementation, number of person in charge of mobility, level of willingness to develop mobility system, focus on car free and strategic mobility challenges) and differences (region, language, regulative factors, normative factors and cognitive factors). To test our conceptual framework, an explorative qualitative case study is done in these two Belgian city local governments. The data collection requires a fieldwork of 12 weeks, 54 internal and external documents, and 20 semi-structured interviews (mobility managers, politicians, sustainability managers, policemen and administrative workers). Results shows differences between the implementation and development of Namur and Leuven. Leuven has an average quality of sustainable mobility control system. Leuven requires developing new adapted indicators to face new city challenges and more effective collaborations between involved departments and actors. The case of Namur shows that its sustainable mobility control system is weak because of the non-adapted indicators to strategy and the weakness of the formal structure of mobility strategy. Results identify different institutional factors that have a significant impact on the development of sustainable mobility strategy; the most relevant are formal regulations, political power, local cultures, support of direct and indirect actors and the sensitiveness on sustainable culture. The proposed conceptual model also highlights if the impact of mobility strategy controls and institutional influences have a weak, medium or strong impact on the development of mobility strategy. Results validate our proposed conceptual model. However, this model has to be tested on other sustainability issues (energy, green building, green housing, green and neutral climate), cities and regions. [less ▲]
