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 ▲]

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 ▲]

Unlike English, little attention has been accorded to orthographic learning in French which has a challenging spelling due to its high level of inconsistency. There is evidence that the mastery of alphabetic decoding is critical to acquire word-specific orthographic representations (Share 1995). It is also generally admitted that orthographic processing skills are involved in orthographic learning beyond the core phonological component. Even if these skills still remain underspecified, research particularly focuses on the sensitivity to orthographic constraints. While Pacton et al. (2013) have shown that graphotactic knowledge influences the learning of new spellings, little is known about the development of this knowledge over time. Our aim was to determine the developmental trajectory of orthographic word form acquisition abilities within the French orthography by assessing the speed of acquisition of new orthographic forms as well as the sensitivity to orthographic regularities. Five groups of forty French-speaking children from grades 2 to 6 took part in the study. We proposed two experimental tasks. The first consisted of an orthographic learning of 10 new orthographic forms (inconsistent in spelling) by using a repeated spelling paradigm. In practice, children were firstly asked to read aloud each item once. Then, the experimenter dictated each item ten times in a mixed order. The capacity of retention of the new representations was assessed one week later with a dictation task. The second task aimed at determining the sensitivity to different French orthographic regularities by means of an orthographic choice task containing 62 pairs of non-words homophones. Moreover, general reading and spelling abilities were also assessed. Results show that the speed of orthographic learning and the capacity of long-term retention significantly increase during the first years but do not differ anymore between grades 4-5 and 5-6, suggesting that older children have reached a nearly maximal potential in their learning capacities. Nevertheless, the general orthographic abilities, which are more dependent on scholar knowledge, continue to develop significantly during school years. Furthermore, sensitivity to orthographic regularities increases significantly only from grade 2 to 3, indicating that children as soon as 9 years-old are already able to extract different graphotactic patterns of their writing system.

Previous studies have clearly demonstrated that the development of orthographic representations relies on phonological recoding. However, substantial questions persist about the remaining unexplained variance in the acquisition of word-specific orthographic knowledge that is still underspecified. The main aim of this study was to explore whether two cognitive factors—sensitivity to orthographic regularities and short-term memory (STM) for serial order—make independent contributions to the acquisition of novel orthographic representations beyond that of the phonological core component and the level of preexisting word-specific orthographic knowledge. To this end, we had children from second to sixth grades learn novel written word forms using a repeated spelling practice paradigm. The speed at which children learned the word forms and their long-term retention (1 week and 1 month later) were assessed. Hierarchical regression analyses revealed that phonological recoding, preexisting word-specific orthographic knowledge, and order STM explained a portion of the variance in orthographic learning speed, whereas phonological recoding, preexisting word-specific orthographic knowledge, and orthographic sensitivity each explained a portion of variance in the long-term retention of the newly created orthographic representations. A secondary aim of the study was to determine the developmental trajectory of the abilities to acquire novel orthographic word forms over the course of primary schooling. As expected, results showedan effect of age on both learning speed and long-term retention. The specific roles of orthographic sensitivity and order STM as independent factors involved in different steps of orthographic learning are discussed. [less ▲]
