This paper examines the level of vibrations transmitted to the crew on a river ship. This ship made a test cruise on the Danube, between Braila and Galati, round-trip (32Km). This cruise was done before the ship was repaired, to compare the levels of vibrations before and after the repairs and to check their efficiency. There were determined both the vibrations produced by the ship's equipment (engine, generator) and those to which crew members are subjected in the areas where they spend most of their time. To det...

Construction and subsequent operation of port complexes leads to increased anthropogenic load on coastal and marine areas. An effective compensatory measure for load reduction is the organization in the neighboring parts of the shores of protected nature areas. We present the study results of the impact of nature protected areas to stabilize the ecological situation in the anthropogenic transformed coastal zone on the example for the port of Bronka, commissioned in 2015. The objects of study are the territory of t...

It is known that the solar-moon tides (SMT) influence often serves as a trigger releasing seismic energy in a prepared area of the earth's crust. The regular increase in the number of earthquakes during the syzygy and perigee was empirically determined at the end of the 19th century by A. Perret [1]. The tidal force reaches its highest value when the perigee coincides with syzygy, which occurs once a year. The such pattern is observed for rock bursts (RB) also. However, it should be noted that the most tide influe...

Between 1990 and 2015, the annual global amount of CO 2 emission generated by transport has increased by 68%, from around 4.6 GtCOGtCO2 to aroaround 7.7 GtCOGtCO2. Technological advances towards eco -friendly vehicles and policy incentives promoting environmentalenvironmental-friendly modes of transport have thus been offset by economic growth and increasing mobility.

Biochar samples were obtained by hydro-pyrolysis (600-800oC) of spent algae material, remaining after extraction of the liquid substances from algae for biodiesel production. The pore structure of the obtained carbon was studied by nitrogen adsorption at -196oC. The most prospective algae biochar sample obtained is distinguished by moderate surface area of 490 m2/g, as well as considerable microporosity (0.15 cm3/g) and mesoporosity (0.13 cm3/g). Pore size distribution show that the pores with size 1-3 nm prevail....

In this paper, we present an area, from the NV of the Transylvanian Basin, which has a particular geological structure. The complex geological aspects begin to be clarified once the Geological Maps 1: 50,000 were made. There is a marginal area in the North-East part, which is a monocline which sinks to the South and South-East. This marginal area is delimited by the sloping area through an important fracture, in the direction of Valley Calda - Gadalin - Gherla. Southwest of this fracture is the area with salt. The...
