The development of riveting technology in iron and steel structures in the 19th and 20th centuries were highly promoted by patents. Although riveting was widely used in buildings and civil engineering structures, little information about the development of this technology – how rivets were manufactured, various installation techniques – is available in literature. This paper discusses a database of patents related to riveting technology that was created to better understand the innovations in riveted connections and their technological evolution. The database includes patents relating to rivets registered in Belgium between 1830 and 1940. Belgian patents are a good proxy for inventiveness in riveting technology in this period, in industrialized countries generally, not only Belgium. As one of the most industrialized countries, Belgium attracted inventors from many countries seeking to register their inventions: foreign inventions represented approximately 75% of all patents. Breakthroughs by important Belgian, French, British, and American inventors/companies are represented in this source. A methodology based on both quantitative and qualitative analyses was implemented. The quantitative analysis dealt with the entire database and explored several key parameters, for example, the subject of the patent and the patenting organization/person. The database also permitted qualitative analyses; specifically, it helped enlarge our understanding of pioneering inventors and their inventions, in the important categories of rivet manufacturing (1855-1870) and installation techniques (1895-1910). As background for the conservation and renovation of historic iron and steel structures, it is vital to have an understanding of the know-how that was available over time. This kind of information is revealed in the patent record [less ▲]

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 ▲]
