Electrocoagulation of a synthetic textile effluent powered by photovoltaic energy without batteries: Direct connection behaviour

The feasibility of using photovoltaic modules to power a continuous 14 L electrochemical reactor applied to remove an azo dye with an efficiency of 70% is reported. The photovoltaic modules were directly connected, and the system efficiency was observed properly maintained when currents were applied in the range of 2.5 to 7.9 A. This value depends on solar radiation. Likewise, it was found that the efficiency depends mainly on the current density and the flow rate prevailing in the reactor.

Lyon Playfair was a champion of scientific and technical education who was professor of chemistry at Edinburgh University before serving as a Liberal M.P., initially for a Scottish university seat, from 1868 to 1892. This article looks mainly at his role in debates on the Education Act of 1872 and the bills which preceded it. Playfair sought to define the democratic traditions of Scottish education, especially emphasising the legacy of John Knox, and to adapt them to the new national system. He idealised the direct connection between parish schools and universities, and the opportunities available to talented boys, using newly available statistics to support his case. He also contributed to the shaping of Scottish secondary education, and to establishing the modern idea of social mobility through educational merit. When the Scottish Office was established in 1885, Playfair opposed the devolution of education and this dissent led him to move to an English seat. His career has a wider interest for the history of Scottish politics in the age of Gladstone.

Discovery of a direct sea route to India: open-sea travel and the Bab el-Mandeb barrier

Open Sea

The issue of discovery of a sea route to India is one of the most important questions about Indo-Roman trade relations and it has yet to be resolved. Historians tend to focus on who and when made the first open-sea journey, and whether it was a sudden change or a process. Conditions essential for discovery of a new route are not considered (not clear – are not considered here, in this paper?), nor are the circumstances that would have made this journey possible. Another issue (of what?) is the case of the Arabia Eudaimon port. The 1st-century AD Periplus Maris Erythraei states that the port had been ransacked and there was no direct connection between India and Egypt, but that all ships were forced to stop there. Thus the resumption of active trade with India necessitated the lifting of the tentative blockade of Arabia Eudaimon and discovering the trans-oceanic route. The nautical guide, however, does not describe the new repute in the context of the troubles in Bab el-Mandeb, but can we be really sure that these two events were not related? What were the circumstances and conditions that had to be met for it to be possible to discover a new route?

Evaluation Techniques

Abstract We have developed a process diagnostics system for photovoltaic energy modules based on standard methods and practices already developed for LSI and MEMS technologies. This paper provides a description of methods used to ensure the conformation of solar cell modules to the rigors of high-quality manufacturing necessary for reliable photovoltaic energy production when exposed to long-term environmental use. We have verified the possibility of inspecting each solar cell and the module assembly in detail for several photovoltaic technologies, specifically monocrystalline Si, polycrystalline Si, and CuInxGa1-xSe2 An objective set of criteria for the quality of each module can be provided by this method for use in module selection by consumers. Moreover, the quality of conformance and reliability data can be used as feedback to the manufacturer to minimize the number of defects created during manufacturing process and ameliorate their effects.

The article evaluates current conditions of international criminalization of offences relating to cultural property and makes a brief historical review of developing international protection of cultural property and elaborating a corresponding notion. Having analyzed the international instruments, the author concludes that offences relating to cultural property may include deliberate seizure, appropriation, demolition as well as any other forms of destruction or damage to objects and items protected under the 1954 Hague Convention for the Protection of Cultural Property in the Event of Armed Conflict committed during international and non-international armed conflicts. These offences do not include such possible acts toward universal cultural values committed either beyond any armed conflict or without direct connection with it. Taking the examples of destruction of Buddhas of Bamiyan, Nimrud, Palmyra, and mausoleums of Timbuktu, the author states that international criminalization of offences relating to cultural property is insufficient, because it does not encompass such cases when objects or items of cultural value are damaged or destroyed under the control of national administrations or with their knowledge.
