The mixed forest of the St. Lawrence valley, which presents jour successive landscapes during its seasonal rhythm, bas been the dorsal spine of Eastern Canada s economy since the establishment of the French colony. The various people who have successively inhabited this forest have either used it as members of the bio-sociological unit or tried to modify its ecology, depending on their traditional culture. It was occupied soon after the glacier recession by the Red-ochre Man, who was followed by the Algonkian forest hunters. Later, the same territory was inhabited by Iroquoian tribes, who brought with them their agriculture which had evolved in the South, but was reoccupied by the Algonkian tribes just before the foundation of Québec. At this time it became a country of European settlers, who carried with them their Old World agriculture and tried to reconstruct in a new continent their Normandie or Poitou landscape. For a newly established agriculturist, the land hardly produced enough for a living. The exploitation of Canadian forests was unpopular amongst the LaRochelle merchants who preferred to trade in the Baltic regions. The first important economic resource was the fur trade. Later, when Napoleon Bonaparte set up a blockade in the Baltic sea, England had to look elsewhere to save and develop her navy and found in the forests of Eastern Canada the pine-trees she needed. Finally, the increase in the number of news-papers, which was largely a consequence of the French revolution, developed another type of forest industry, the production of spruce pulp.

In 1792, the French Revolution became a thing in itself, an uncontrollable force that might eventually spend itself but which no one could direct or guide. The governments set up in Paris in the following years all faced the problem of holding together against forces more revolutionary than themselves. This chapter distinguishes two such forces for analytical purposes. There was a popular upheaval, an upsurge from below, sans-culottisme, which occurred only in France. Second, there was the “international” revolutionary agitation, which was not international in any strict sense, but only concurrent within the boundaries of various states as then organized. From the French point of view these were the “foreign” revolutionaries or sympathizers. The most radical of the “foreign” revolutionaries were seldom more than advanced political democrats. Repeatedly, however, from 1792 to 1799, these two forces tended to converge into one force in opposition to the French government of the moment.

This study investigates a water transport features by extending Copernicus Marine Environment Service (CMEMS) to the Liepaja coast-port-channel-lake system with a two-way nested model. The Liepaja lake and Liepaja port are connected by Trade channel. The Liepaja port has three gates—the openings in wave breakers connecting the port aquatory with the Baltic sea. Each of gates has a corresponding dredged channel for securing the navigation. A hydrodynamic model is set up to study the flow and water level in this system. The area of the port gates, port and Trade channel are resolved by 33 m grid. The model results are verified against currents and sea level observations inside/outside port, Trade channel and Liepaja lake. Results and observations show that strong currents occur in the Trade channel in case of rapid sea level change in Baltic sea despite the Trade channel is rather shallow at the connection with Liepaja lake. The northern part of the Liepaja lake gets filled with brackish water during storm surge events. The channel has notable alternating current also during a relatively calm weather due to the port seiches. Long and narrow shape of the channel implies the Helmholtz type oscillations between the lake and the port with a period in approximately semidiurnal range. Hydrodynamic simulations describe well these oscillations but the phase of hourly scale oscillations in the port may differ in case of weak external forcing. Water exchange is significantly increased by the transit (gate to gate) sea currents. This transit flow usually occurs between South or Central gate and the North gate carrying sea water into the port. Northward flow of the surface layer is more characteristic in the port aquatory due the prevailing south-western winds. There are intense morphological processes at the coastline and underwater slope near the Liepaja port due to a sandy western coastline of Latvia, long fetch of the waves and strong currents at the port gates. Liepaja port is one of the Latvian ports in HywasPort operational service of hydrodynamics, waves and siltation.

Camelina [Camelina sativa (L.) Crantz] has potential in aquaculture, livestock feed production, and the biofuel industry. It is necessary to determine the appropriate production technology for the newly introduced crop under different environmental conditions. The objective of this 2-year study was to measure the response of five camelina genotypes in terms of seed yield, yield components, and disease incidence to applied nitrogen (N) at multiple sites in the Maritime provinces of eastern Canada. The factorial experiment was set up as a randomized complete block design. The two factors were six N rates (0, 25, 50, 100, 150, and 200 kg ha−1 N) and five genotypes of camelina (Calena, CDI002, CDI005, CDI007, and CDI008). The interactive effect of N rates and genotypes was considered. Results showed that camelina, which is usually considered a low-input crop, responded positively to increased applied N at rates up to 200 kg ha−1 N. Seed yield responded differently to applied N rates depending on genotype. Branch and pod development were decisive for seed yield. The advanced line CDI007 had the highest yield potential among the five genotypes. Downy mildew infection was positively correlated with applied N rates; however, seed yield was not significantly affected by downy mildew infection.

ABSTRACT The increase in pollution by oil spills in the Baltic has lead to the Minister of Transport to set up a committee with the task to find methods for identifying ships responsible for oil spills. A preliminary study of the oil transport situation in Sweden had shown that the fingerprint method for identification will be difficult to use. The study also showed that microparticles of plastic and metal as tags might be used. In most cases the oil spills in the Baltic are due to pumping out residues mixed with ballast. In the present paper the merits of different methods for tagging these residues, including the cost aspect, are treated as well as identification of recovered oil samples. In a field experiment the oil residues in a tanker were tagged. Some of its tanks were tagged with plastic particles and some with metal particles. The tanks were treated in different ways for cleaning and the oil-water mixtures were then pumped out in the sea under controlled conditions. The different spills were kept inside an enclosure for a fortnight and samples were taken every day. In all analysed samples the tagged substance could be recovered and identified. A plan for testing this method on a larger scale is under preparation.

<p>Submarine groundwater discharge (SGD) is an important pathway for water and compounds within the land-ocean transition zone that can impact coastal environments and marine life. Although SGD research from sandy shorelines has rapidly advanced in recent years, there is very little understanding of coastal areas dominated by coastal peatlands, where the prevailing soils are characterized by a low hydraulic conductivity. Peatlands, the world’s most efficient carbon storage, could be a potential source of carbon, nutrients, and trace metals via the SGD pathway. The objective of this study was to determine the magnitude and location of SGD in a coastal peatland in northeast Germany. We wanted to understand the factors controlling terrestrial SGD from coastal peatlands through numerical modelling employing the HYDRUS-2D modeling package. Steady-state scenarios were simulated based on soil physical properties, hydraulic heads, and geological stratifications and structure. In the model set-up, emphasis was laid upon peat layers extending from land into the sea. Our results show that terrestrial SGD occurs at a net discharge volume flux of 0.0803 m<sup>3</sup> m<sup>-1</sup> d<sup>-1</sup> with seepage rates of 1.05 cm d<sup>-1 </sup>near the shore and 0.16 cm d<sup>-1 </sup>at a second discharge region above the submerged peat layer. Calculated seepage rates compare to observations from other SGD sites in the Baltic Sea region and other wetland environments. The upscaled SGD estimate for the 3-km coastal peatland is 240 m<sup>3</sup> d<sup>-1</sup>, which is in correspondence to earlier estimates from the same site. Analysis of the model output reveals that magnitude and location of terrestrial SGD are mainly driven by the magnitude of hydraulic gradient and the hydraulic conductivity of both peat and mineral soils. Additional influencing factors are peat anisotropy, thickness of aquifer sands and peat layers, and peat elevation. Submerged peat layers extending into the sea can restrict SGD flow in deeper discharge regions but may be less critical in terms of volume flux as most SGD occurs near the shoreline. We conclude that coastal peatlands could be an essential source of carbon, nutrients, and other compounds via SGD and may influence local geochemistry budgets and marine ecosystems.</p>

Hegel’s philosophy of history emphasizes the development of freedom and the consciousness of freedom over the course of world history. For G. W. F. Hegel (b. 1770–d. 1831), this development is marked by conflict and struggle, rather than smooth uninterrupted progress, and is manifested for the most part in political developments construed broadly, including world-historical events such as the French Revolution, in the significant actions of world-historical “heroes” such as Alexander the Great and Napoleon Bonaparte, and in the achievements of peoples and nations. According to Hegel, the end or goal of history is the actualization of freedom in the life of the modern nation-state. He claimed that history was a rational process of development and that it could be understood and made intelligible for anyone willing to look at it rationally, which means looking at it holistically and as an endeavor of the World Spirit with a discernible purpose. Moreover, he attempted to show that history exhibited real progress toward the ultimate goal of freedom and that the modern period, the time in which he lived up until his death in 1831, brought this development to fruition and, in a way, a culmination. This theory of history has been both highly influential and controversial—it is essential to any overall study of the philosophy of history.

Abstract Obtaining high harvester efficiency in young pine stands during early thinning is achallenging management practice. One of the difficulties lies in achieving the optimal use of the tree trunk for assortments and obtaining satisfactory timber quality. The objective of this research was to find out 1) how much of the tree trunk can be processed by a harvester to produce logs, and 2) the quality of the assortments in terms of log length accuracy and delimbing quality. The work was carried out in a 31-year-old pine stand in northern Poland with the Vimek 404 5T harvester with the Keto Forst Silver head for early thinning. Eighty sample plots were set up within the stand for detailed tree analysis after harvesting. The total length of the assortments from each tree was measured as well as the minimal top diameter (under bark). Additionally, the lengths of the bottom, middle and top logs were measured as well as the height of the knots after delimbing. On average, 70% of the total tree height was used for assortments and logs were processed up to a mean top diameter of 5.3 cm under bark. The length accuracy was very high: 90% of the logs had the expected length, more than 9% had a commercially acceptable length, while only 0.7% of the logs were too long. After delimbing, the knots were of a maximum height of 2 cm. Using the Vimek 404 5T harvester in the 31-year-old pine stand was an effective solution for trunk processing and obtaining quality assortments.

One of the memorable days in the French revolution of 1848 occurred on May 15. Several extraordinary events happened on that date. The first was the overrunning of the legislative chamber by an unruly crowd. Next, and most important, a person named Aloysius Huber, after several hours had elapsed, unilaterally declared the National Assembly dissolved. In the resultant confusion, the legislators and the crowd dispersed. Third, shortly afterwards, an attempt took place at the City Hall to set up a new revolutionary government. It failed completely. As the result of these happenings, a number of people thought to be, or actually, implicated in them were imprisoned on charges of sedition.

Napoleon Bonaparte turned France into a police state during his reign.[1] However, he did not continue the French Revolution as the French people hoped. The French Revolution brought forth liberty and to do as ones will if it does not harm another.[2] A new document brought by the French Revolution embodying these principles was the French Declaration of Rights of Man and Citizen in 1789.[3] This Declaration stated under article 11 that there was to be a free flow of ideas and opinions in writing and the press.[4] Article 7 outlawed any cruel harsh punishment and arbitrary sentencing.[5] However, Napoleon reversed these fundamental principles of the French Revolution. Writers, the press, along with the French people were subjected to the General police and prefects and were banned from saying anything controversial, against his regime, anything about France’s revolutionary past, and against France’s allies.[6] Arbitrary, cruel punishments, and harsh rules were enacted by Napoleon through the Penal Code in 1810.[7] Napoleon did not continue the French Revolution and reversed it by turning France into a police state and monitored and censored the French people, the press, and writers.
