Introduction: Epidemiological study of Traumatic Brain Injury (TBI) and the improvement of the organizational capabilities of medical care at all stages of its provision plays an important role in forecasting and social and labor rehabilitation of the sailing crew. Planning the development of the neurosurgical service of port hospitals is impossible without knowing the structure of TBI, both in severity and sectoral, occupational and territorial prevalence. Materials and methods: The analysis of the treatment of 92 patients from members of the vessel`s crew who received industrial TBI with a disability while performing voyage tasks in the northern water basin was carried out. When working on the material, analytical and statistical methods were used. The significance of differences was calculated using a t-test for independent samples. Results: In the general structure of traumatism of the studied contingent of the members of the vessel`s crew, TBI accounted for 4.1% of cases, while in the territorial population, they reach 30.0% - 40.0%. Most of the victims worked in the transport fleet of the northern water basin - 68.7% (9.4), while in the fishing fleet - 17.2% (3.3) and the river fleet - 14.1% (4.6). Command staff: navigators (10.5), captains (10.1), chiefs of radio stations (7.4), skippers (6.8), as well as boatswains (27.8), who are responsible for organizing and conducting deck operations, receive TBI 4.0 - 2.5 times more often than rank-and-file personnel. This distribution becomes easy to understand if we take into account that 43.4% of the damage was sustained during the performance of ship operations related to movement on ladders and decks, in the engine room, and their hasty execution by the supervisors in the absence of safety precautions leads to severe TBI. The members of the vessel`s crew receive them several times less often when performing loading and unloading operations (0.9), closing holds (0.4), mooring, and servicing deck mechanisms (0.2 each). The probability of getting TBI is especially high during the first three years of work in the specialty (34.8% of all injuries). With an increase in work experience, injuries decrease by more than 1.4 times among workers with 15 years of work experience. Every third TBI (36.5%) on ships is associated with a fall of the victim from a height, that is, it is a catatrauma. All injuries arise from collisions with blunt objects. Discussion: Every twenty-fifth work-related injury with loss of ability to work, sustained by the members of the vessel`s crew of the northern water basin, while performing ship operations, is a TBI. The minimum knowledge required for shipboard crew members, and ship managers to suspect this life-threatening condition, is given during an injury first aid session that is required by the ship’s medical officer. Conclusion: 1. In the general structure of industrial injuries of the studied contingent of the members of the vessel`s crew, TBI accounted for 4.1% of cases, while in the territorial population, they reach 30.0% - 40.0%. The incidence of TBI in men from among the members of ve+-ssel`s crew is only 1.5 times higher than in women and is the highest in people under 20 years of age (4.8%; 11.0). 2. Most of the victims worked in the transport fleet of the northern water basin - 68.7% (9.4), while in the fishing fleet - 17.2% (3.3) and river - 14.1% (4.6). The members of the vessel`s crew receive them several times less often when performing loading and unloading operations (0.9), closing holds (0.4), mooring, and servicing deck mechanisms (0.2 each). Every third TBI (36.5%) on ships is associated with a fall of the victim from a height, that is, it is a catatrauma. 3. TBI, accompanied by a concussion, in the northern basin accounts for up to two-thirds of all head injuries, of which 69.5% fall on the most able-bodied and productive age of workers (20-39 years). Concussions occur 4 times more often in the transport fleet than in the fishing and river fleet. Sailors and minders make up 44.3% of the victims. Falls from a height onto decks, mooring lines, into the hold, or overboard were the cause of 78.5% of concussions. 4. Mild brain contusions are a rarer pathology and occur mainly in transport and fishing fleets with rank-and-file personnel during falls from a height. 5. Brain contusions of moderate and severe degrees occur only in the transport fleet in the youngest men: in every second case, the patients were 20-29 years old. Every third victim is a sailor, every sixth is a minder. A severe degree of brain injury was more often observed in persons who received TBI while servicing deck mechanisms, moving along ladders, and mooring operations. More than half of them are associated with falls from a height.

Recently smart materials play an important role in different aspects of the industry due to their specific characteristics. The properties of these materials can change spontaneously in interaction with the immediate surrounding without any external power consumption. Phase change materials are a great division of smart materials with considerable capacity to absorb and release thermal energy during the phase change process. They can also handle temperature regulations since the phase change process occurs at a constant temperature. The implementation of PCMs is one of the potential passive cooling strategies which has received increasing attention in recent years. This paper aims to briefly review the various types of PCMs which can be used for passive cooling in buildings.

This paper presents aspects of underwater cultural heritage management in Greece, focusing mainly on accessibility to the diving community and the general public. More specifically, it discusses different approaches to the protection and enhancement of Underwater Archaeological Sites, already put into practice over the last years (2018-2021) by the Ephorate of Underwater Antiquities, the public service of the Hellenic Ministry of Culture and Sports responsible for the management of underwater heritage. Moreover, it analyses the aspirations for the future, as these took shape already at the beginning of 2021. Lately, cultural management has turned into a fast-growing sector with multilevel developmental prospects. In order to tap into the underwater cultural heritage potential, we must always take into consideration the identity and special characteristics of each underwater site as well as the different possibilities of access — physical or virtual — that are rapidly changing because of new technological achievements. All these parameters affect significantly decision making and the undertaking of relevant initiatives. Examples of the pilot implementation of the opening of underwater archaeological/cultural sites to the public will be presented. Through them, preliminary conclusions concerning the efficacy of the selected managerial approaches can be drawn, while at the same time domains where more should be done will be highlighted.

This paper is an overview of the main characteristics of Sardina on the Moroccan Atlantic coast. Sardine occupies an important place in the socio-economic context of Morocco and is the main species exploited on Moroccan coasts. It is the most important species in terms of catches and biomass. The small pelagic stocks in the area are exceptional wealth and as many opportunities in an international context, marked both by the scarcity of the resource and the need to make the sea c contribute more to food security and economic growth. The aim of this work is the study some features of S. pilchardus in the Moroccan waters.

Nile tilapia (Oreochromis niloticus) are herbivores with longer coiled intestines compared to carnivores; mouth characteristics necessary for plant shredding. Hence, several studies have been conducted to replace feed ingredients in the diet of Nile tilapia considering the increasing cost. In this study, Water spinach (Ipomoea aquatica) was evaluated as a potential feed ingredient for Nile tilapia. A six months feeding trial was conducted to assess the effects of water spinach fish feed composition on the performance of Nile tilapia fingerlings. Five diets were formulated containing 0% (control diet), 5%, 10%, 15% and 20% water spinach composition. Each treatment was carried out in triplicate using 30 Nile tilapia juveniles per replicate with an initial mean weight of 2±1g. The fish were fed at 5% body weight twice per day. Water quality monitoring was done every morning before feeding. There was no significant (p > 0.05) variation in water quality parameters between all the treatments. The best growth performance was recorded from a fish-fed 5% diet (180.49±0.83 g), while fish fed with a 20% diet had poor growth performance (128.98± 0.80g). The highest SGR was obtained in fish fed with a 5% diet (1.34±0.05) while the lowest was obtained in fish fed with a 20% diet (1.09±0.05). Except for SGR, WG, FL, and FW, there was no significant difference (P>0.05) in other growth parameters of all the treatments. Final weight had a significant difference as determined by One-Way ANOVA (F (4,316) =6.363, P=0.00) between 15% and 20% water spinach composition compared to 5% water spinach composition. Therefore, 5% water spinach composition had the best growth performance.
