The seaweed resources of Portugal

Abstract Continental Portugal and its two archipelagos (Azores Islands and Madeira Islands) present a very interesting and diverse seaweed community. Its great diversity results for example from different environmental conditions such as the latitudinal gradients that affect the continental Portugal coastal shoreline in unique ways. The first Portuguese phycological studies published date from the end of the 18th century and seaweeds have been harvested to be used as fertilizer since at least the 14th century. However, Portuguese seaweeds are still a natural and valuable resource that is relatively under explored or studied, particularly regarding its economic potential. Although Portugal was one of the world’s main agar producers in the past, the sustainability of its seaweed exploitation was overlooked. Contemporary awareness of this valuable resource might bring together role players such as researchers and industries towards innovative and sustainable practices (such as to make use of non-indigenous species that have been registered in the country). Nowadays, almost all Portuguese higher education institutions currently have research groups dedicated to studies related to seaweeds (ranging from ecological and environmental assessment studies to seaweed aquaculture, uses and applications). This work addresses the diversity of Portuguese seaweeds and its main economic aspects.

The present study investigates macrofouling development in the Mar Grande of Taranto (Central Mediterranean Sea), a wide confined area that has attracted considerable attention in recent years due to the establishment of numerous non-indigenous species (NIS). Different starting times of a yearly primary succession on artificial substrates were tracked so as to investigate the matching of the development pattern with contingency and/or convergence models, identifying NIS’s structural role in the community endpoint. Our results show that during the experiment all assemblages tended to converge towards multiple contingent communities according to starting times and depths. The differences are due to propagule availability which influence further species interactions. Thus the endpoint patterns are defined by a contingent community development determined by the seasonal species pool, their phenologies, pre- and post-settlement events, and species interactions. The most important structuring species was Mytilus galloprovincialis, which was present in almost all the endpoint assemblages, in particular when it recruits at early stages of the community development. Another abundant species at the endpoint was the alien Branchiomma boholense; which was a persistent structural component contributing to an alternative state in which Mytilus galloprovincialis loses its structural importance and where B. boholense becomes dominant, leading to an increase in fouling biodiversity of the endpoint assemblage.

Gammarus roeselii is one of the successful non-indigenous species recently established in the Ticino River basin (Northern Italy). G. roeselii is not usually considered to be a real threat to native gammarids because no evidence has been reported so far on its effects on biodiversity and habitats. In this study, we assessed the spatial distribution of G. roeselii in the secondary hydrographic system of the southern part of the sub-lacustrine Ticino River basin and examined substrate preferences on the basis of laboratory experiments. We found that G. roeselii is well established in this area, occurring in almost all the seminatural streams, reaching high densities. Furthermore, we found that this species has a preference for two distinct types of substrate: empty shells of the bivalve Corbicula fluminea, which provide a suitable shelter for the introduced amphipod, and aquatic plants, which provide food resources. Conversely, preference for inorganic substrates, such as stones, was lower. In addition, the results indicate that G. roeselii easily inhabits the water column. The high adaptability of G. roeselii, combined with its capacity to exploit different niches and its swimming ability, are ecological characteristics that can favour its colonisation of new areas.

Masking is a phenomenon that is traced to almost all human ages. From its prehistoric and primitive narratives in Africa, its dramatic beginnings in ancient Greece and Rome, to its use as forms of character delineation in the commedia dell’Arte of the 16th and 18th century Europe, as well as its age long association with carnivals due largely to its analogous to humour and entertainment. Masking, as comic as it may seem, has been critical of humanity’s social dispositions from time past. As humans, the façade of the mask is a leeway to speak truth to power and also an opportunity for the performance of self in ways that are at variant with the real self. As topical as the activities of the masquerade are to the society, no academic quest has been directed to investigate how humour and satire have always been associated with the masquerade. Following the social criticism, humour and entertainment which have become evidently inherent in the emergent stand-up comedy, scholars have directed their critical attention towards this new live theatre without considering the humorous functions of the masquerade for an academic enquiry. It is against this backdrop that this paper has decided to investigate and re-establish historically the humorous contributions of the masking art in almost all facets of human conditions. The resources for the paper were a combination of library and historical research. The paper established that satire and humour, as enjoyed in all venues of stand-up comedy acts in Nigeria, are just a contemporary addition to what masks had done in the past but for dearth of proper documentation of these contributions. The masking tradition has been a source of humour and sarcasm to issues bordering on human relations all over the world

This paper presents the highlights of the third annual edition of the BP Energy Outlook, which sets out BP’s view of the most likely developments in global energy markets to 2030, based on up-to-date analysis and taking into account developments of the past year. The Outlook’s overall expectation for growth in global energy demand is to be 36% higher in 2030 than in 2011 and almost all the growth coming from emerging economies. It also reflects shifting expectations of the pattern of supply, with unconventional sources — shale gas and tight oil together with heavy oil and biofuels — playing an increasingly important role and, in particular, transforming the energy balance of the US. While the fuel mix is evolving, fossil fuels will continue to be dominant. Oil, gas and coal are expected to converge on market shares of around 26—28% each by 2030, and non-fossil fuels — nuclear, hydro and renewables — on a share of around 6—7% each. By 2030, increasing production and moderating demand will result in the US being 99% self-sufficient in net energy. Meanwhile, with continuing steep economic growth, major emerging economies such as China and India will become increasingly reliant on energy imports. These shifts will have major impacts on trade balances.

The article is devoted to the study of inscriptions on the gravestones of Haji Ibrahim al-Uradi, his father, brothers and other relatives. The information revealed during the translation of these inscriptions allows one to date important events from the history of Highland Dagestan. Also we can reconsider the look at some important events from the past of Hidatl. Epitaphs are interesting in and of themselves, as historical and cultural monuments that needed to be studied and attributed. Research of epigraphy data monuments clarifies periodization medieval epitaphs mountain Dagestan using record templates and features of the Arabic script. We see the study of medieval epigraphy as one of the important tasks of contemporary Caucasian studies facing Dagestani researchers. Given the relatively weak illumination of the picture of events of that period in historical sources, comprehensive work in this direction can fill gaps in our knowledge of the medieval history of Dagestan. In addition, these epigraphs are of great importance for researchers of onomastics, linguistics, the history of culture and religion of Dagestan. The authors managed to clarify the date of death of Ibrahim-Haji al-Uradi, as well as his two sons. These data, the attraction of written sources and legends allowed the reconstruction of the events of the second half of the 18th century. For example, because of the epidemic of plague and the death of most of the population of Hidatl, this society noticeably weakened and could no longer maintain its influence on Akhvakh. The attraction of memorable records allowed us to specify the dates of the Ibrahim-Haji pilgrimage to Mecca and Medina, as well as the route through which he traveled to these cities.

Century Science

This chapter discusses the process of building research teams. Increasingly over the past three-quarters of a century, science has become a collective activity, with teams of tens, hundreds or even thousands of scientists, engineers and technicians working together on a common goal. Consequently, almost all research involves building, motivating and maintaining a research team. Even a theoretical group is likely to have one or two postdocs, graduate students and visitors, but research teams will, in addition, have engineers and technicians, as well as, possibly, research administrators. The chapter also addresses the importance of creating and maintaining a good team and team spirit, as large projects are assembled from a large number of small teams working on common goals, usually in a loose federated structure with some overall coordination and leadership.

Electronically Controllable

For the past two decades, many research groups have investigated new methods for reducing the size and cost of safe and arm-fire systems, while also improving their safety and reliability, through batch processing. Simultaneously, micro- and nanotechnology advancements regarding nanothermite materials have enabled the production of a key technological building block: pyrotechnical microsystems (pyroMEMS). This building block simply consists of microscale electric initiators with a thin thermite layer as the ignition charge. This microscale to millimeter-scale addressable pyroMEMS enables the integration of intelligence into centimeter-scale pyrotechnical systems. To illustrate this technological evolution, we hereby present the development of a smart infrared (IR) electronically controllable flare consisting of three distinct components: (1) a controllable pyrotechnical ejection block comprising three independently addressable small-scale propellers, all integrated into a one-piece molded and interconnected device, (2) a terminal function block comprising a structured IR pyrotechnical loaf coupled with a microinitiation stage integrating low-energy addressable pyroMEMS, and (3) a connected, autonomous, STANAG 4187 compliant, electronic sensor arming and firing block.

Exposure Prophylaxis

AbstractTransgender women face a serious risk of HIV infection. Despite this, there is limited knowledge and use of Pre-exposure prophylaxis (PrEP). We measured the continuity of prevention across services in the PrEP cascade and correlates of PrEP use among trans women in San Francisco enrolled in the 2019/20 National HIV Behavioral Surveillance Study. Knowledge and use of PrEP among trans women in San Francisco increased in recent years; almost all (94.0%) had heard about PrEP, 64.7% had discussed PrEP with a healthcare provider, and 44.8% had taken PrEP in the past 12 months. PrEP use was associated with participation in a PrEP demonstration project (aOR = 31.44, p = 0.001) and condomless receptive anal intercourse (aOR = 3.63, p = 0.024). Injection drug use was negatively associated (aOR = 0.19, p = 0.014). Efforts are needed to combat the gender-based stigma and discrimination faced by trans women, which can result in avoidance and mistrust of the medical system.
