The basic concepts safety at sea and the maritime safety system have remained almost unchanged for a comparatively long time. However, the components and elements of these concepts are now subject to many changes created by the ‘information age’. This paper presents thoughts on today's concept of the maritime safety system, its main components and their elements. Although the thoughts and ideas presented are those of the authors, they take account of the legal instruments in force and recent developments in technology, especially developments in radio-communications. The paper provides an overall review of the institutions, regulations and procedures concerned with safety at sea.

Main Components

Development in the current development sector has grown rapidly, in this development we can see a good potential to be developed, namely the development of bricks with good quality compared to using red bricks which production takes a long time. Batako is an alternative that can be used in the construction of a building, because currently the price of red brick is quite high because the production cost is quite expensive. Besides, the price of firewood used for cooking red brick is getting difficult. Meanwhile, the demand for brick gradually increased because brick was one of the main components in building construction. So it needs to be developed in making brick blocks because the time is relatively short in the drying process. Therefore the community service team made a brick making machine with a vibration system for compaction and a faster production process in brick making using a machine that has been made, so that it can increase partner income, who previously produced 120 pieces with a manual system using a machine that could produce 500 pieces of brick per day.

The influence of recreation being a set of measures to restore health and recreation, on the main components of forest phytocenoses in specially protected natural territories of the Tatishchevsky district of the Saratov region has been studied for the first time. These phytocenoses have been intensively used for tourism for a long time. The intensity and visits activity of protected areas has been determined; the recreational capacity of territorial objects has been studied. The degree of forest landscapes has been revealed in specially protected natural territories. The findings allow predicting the future state of the natural resources of the Saratov region and can be taken into account when assessing their optimal use.

The mutual interaction between spin current and magnetization is a key phenomenon in spintronics. This interaction leads to a spinmotive force, a mechanism of energy-transfer from magnetization into conduction electrons. In this paper, the basic concepts and recent developments of the spinmotive force are introduced.

Anomalous Signal

Single wavelength anomalous diffraction (SAD) is a powerful experimental phasing technique used in macromolecular crystallography (MX). SAD is based on the absorption of X-rays by heavy atoms, which can be either incorporated into the protein (crystal) or naturally present in the structure, such as sulfur or metal ions. In particular, sulfur seems to be an attractive candidate for phasing, because most proteins contain a considerable number of S atoms. However, the K-absorption edge of sulfur is around 5.1 Å wavelength (2.4 keV), which is far from the optimal wavelength of most MX-beamlines at synchrotrons. Therefore, phasing experiments have to be performed further away from the absorption edge, which results in weaker anomalous signal. This explains why S-SAD was not commonly used for a long time, although its feasibility was illustrated by the ground-breaking study by Hendrickson and Teeter [1]. Recent developments in instrumentation, software and methodology made it possible to measure intensities more accurately, and, as a consequence, S-SAD has lately obtained more and more attention [2]. The beamline BL-1A at Photon factory (KEK, Japan) is designed to take full advantage of a long wavelength X-ray beam at around 3 Å to further enhance anomalous signals. We performed S-SAD experiments at BL-1A using two different wavelengths (1.9 Å and 2.7 Å) and compared their phasing capabilities. This methodological study was performed with ferredoxin reductase crystals of various sizes. In order to guarantee statistical validity and to exclude the influence of a particular sample, we repeated the comparison with several crystals. The novelty in the approach consists in using very long wavelengths (2.7 Å), not fully exploited in the literature so far. According to our study, the 2.7 Å wavelength shows - despite strong absorption effects of the diffracted X-rays - more successful phasing results than at 1.9 Å.

Natural Honey

Honey is produced by bees (Apis mellifera) from flower nectar and insect secretions. Like other bee products it is used as an adjuvant for treatment of many diseases. It also finds its uses for producing cosmetics. The main components of honey include carbohydrates, which represent approximately 80% of the dry matter, and water. Monosaccharides, mainly fructose and glucose, constitute approximately 70% of the sugars, whilst the remaining saccharides are disaccharides and oligosaccharides. Moreover, honey consists vitamins, minerals, polyphenols, amino acids and enzymes. Beneficial effect of natural honey on human health has been known for a long time because of its biological and therapeutic properties. It is used to treat some cardiovascular and gastrointestinal diseases. Among the best-known properties of honey are its antibacterial, antifungal, antiviral and anti-inflammatory activities. Important is also its antioxidant activity, which could be useful for producing anti-aging cosmetics.

Reactive Oxygen Species (ROS) play an essential dual role in living systems. Healthy levels of ROS modulate several signaling pathways, but at the same time, when they exceed normal physiological amounts, they work in the opposite direction, playing pivotal functions in the pathophysiology of multiple severe medical conditions (i.e., cancer, diabetes, neurodegenerative and cardiovascular diseases, and aging). Therefore, the research for methods to detect their levels via light-sensitive fluorescent probes has been extensively studied over the years. However, this is not the only link between light and ROS. In fact, the modulation of ROS mediated by light has been exploited already for a long time. In this review, we report the state of the art, as well as recent developments, in the field of photostimulation of oxidative stress, from photobiomodulation (PBM) mediated by naturally expressed light-sensitive proteins to the most recent optogenetic approaches, and finally, we describe the main methods of exogenous stimulation, in particular highlighting the new insights based on optically driven ROS modulation mediated by polymeric materials.

Pyrolysis Of Biomass

Pyrolysis of biomass materials can implement the efficient conversion of biomass to gaseous, liquid and solid energy products. Compared with experimental research which needs massive apparatus and funds and also takes long time, the computer simulation of biomass pyrolysis is more convenient and flexible to achieve the main characteristics of the process. Simulation of thermodynamic equilibrium for the pyrolysis of rice husk was studied in this paper. Based on the minimization of Gibbs free energy, MATLAB was used to calculate thermodynamic equilibrium for the pyrolysis of rice husk in the temperatures ranges from 523 K to 1723 K at intervals of 100 K. The results showed that the contents of H2 and CO increased rapidly with the temperature from 723 K to 1223 K, while the contents of H2O, CH4, CO2 and C decreased sharply. When the temperature was higher than 1223 K, the yields of H2 and CO reached the maximum of 51 mol% and 48 mol% respectively, and then kept stable. In order to be closer to experimental results, the constrain conditions of element C in tar was introduced in the calculations. The results indicated that, in the main components of tar from 523 K to 1223 K, the contents of naphthalene and toluene both decreased and then toluene vanished gradually. However, the content of benzene increased with increasing temperature and finally became the dominant product when the temperature was above 1300 K.
