Microalgae are microscopic plants inhabiting the world?s oceans and other aquatic environments. They are critical for the health of the planet, being responsible for at least half of the global primary productivity. Like other photosynthetic (autotrophs) organisms, microalgae capture solar radiation and convert it to chemical energy as biomass, forming the basis of aquatic food webs, fixing carbon dioxide and producing oxygen as part of the process. Other microalgae (heterotrophs) can utilise organic compounds for growth. As single-celled packages of bioactive molecules that can be cultured to produce high levels of biomass, microalgae are a renewable resource with a wide range of applications in bioindustry. Their use is established in the human nutraceutical industry with ?super foods? such as Spirulina from the cyanobacterium (blue green alga) Arthrospira platensis (Figure 1). Intense interest surrounds the development of microalgae as a source of biofuels, and in the mitigation of CO2 and other greenhouse gases (GHG). Other bioactive compounds, as well as genes from microalgae, offer new opportunities for bioindustry.

The round-the-world transition of m/v Katherine ship is considered. The aim of this work is to minimize the Energy Efficiency Operational Indicator (EEOI) of the vessel, and, accordingly, to minimize the ship's fuel consumption and carbon dioxide emission depending on the parameters of sea transition: Vs, mass of transported cargo, and the distance of the passage. For specifically selected ship power plant (SPP), the parametric dependence of Vs and fuel consumption on the share of used power is determined by calculation method. The Energy Efficiency Design Index (EEDI) is determined by the model given in Resolution MEPC.212(63). The EEOI is determined depending on the ship fuel consumption, the carbon concentration in the ship’s fuel with the main parameters accepted for transition Vs, transported cargo mass , the sea passage distance . Calculation studies are conducted in a wide range of sea transition parameters – transition distance within 200 to 2,800 nm, the Vs from 0.01 to 24.0 knots, cargo mass ranging within 4,000 to 70,000 tons.

Abstract A. philoxeroides is one of the worst weeds in the world because it invades both terrestrial and aquatic habitats. The aquatic form of the plant has the potential to become a serious threat to rivers, waterways, wetlands and irrigation systems. The terrestrial form grows forming dense mats with a massive underground rhizomatous root system (ISSG, 2016). This weed is extremely difficult to control, is able to reproduce from plant fragments and grows in a wide range of climates and habitats, including terrestrial areas. In aquatic habitats it has deleterious effects on other plants and animals, water quality, aesthetics, vector populations, water flow, flooding and sedimentation. In terrestrial situations, it degrades riverbanks, pastures, and agricultural lands producing massive underground lignified root systems penetrating up to 50-60 cm deep. Currently, A. philoxeroides is listed as invasive in the United States, Puerto Rico, France, Italy, India, Sri Lanka, China, Taiwan, Indonesia, Myanmar, Singapore, Australia and New Zealand (Weber et al., 2008; Chandra, 2012; Rojas-Sandoval and Acevedo-Rodriguez, 2015; DAISIE, 2016; USDA-ARS, 2016; USDA-NRCS, 2016; Weeds of Australia, 2016). Once established, it behaves as an aggressive invader with the capability to totally disrupt natural aquatic ecosystems, shoreline vegetation and terrestrial and semi-aquatic environments (ISSG, 2016; USDA-NRCS, 2016).

The world is confronted with the depletion of natural resources due to their unsustainable use and the increasing size of populations. In this context, the efficient use of by-products, residues and wastes generated from agro-industrial and food processing opens the perspective for a wide range of benefits. In particular, legume residues are produced yearly in very large amounts and may represent an interesting source of plant proteins that contribute to satisfying the steadily increasing global protein demand. Innovative biorefinery extraction cascades may also enable the recovery of further bioactive molecules and fibers from these insufficiently tapped biomass streams. This review article gives a summary of the potential for the valorization of legume residual streams resulting from agro-industrial processing and more particularly for pea, green bean and chickpea by-products/wastes. Valuable information on the annual production volumes, geographical origin and state-of-the-art technologies for the extraction of proteins, fibers and other bioactive molecules from this source of biomass, is exhaustively listed and discussed. Finally, promising applications, already using the recovered fractions from pea, bean and chickpea residues for the formulation of feed, food, cosmetic and packaging products, are listed and discussed.

The paper reflects the specificity of the fundamental ideas of the artistic world of M. G. Atamanov, which includes a wide range of literary facts from the content level of the text of the works to their poetics. A particularly important role in the works of M. G. Atamanov is played by cross-cutting themes and images that reflect the author's individual style and his idea of national-ethnic identity. The subject of the research is the book of essays “Mon - Udmurt. Maly mynym vös’?” (“I am Udmurt. Why does it hurt?”), which most vividly reflected the main spiritual and artistic searches of M. G. Atamanov, associated with his ideas about the Udmurt people. The main motives and plots of the works included in the book under consideration are accumulated around the concept of “Udmurtness”. The comprehension of “Udmurtness” is modeled in his essays through specific leit themes: native language, Udmurt people, national culture, mentality, geographic and topographic features of the Udmurt people’ places of residence, the Orthodox idea. The “Udmurt theme” is recognized and comprehended by the writer through the prism of national identity.

Numerous O (oxa)- and S (thia)-glycosyl esters and their analogous glycosyl acids have been accomplished through stereoselective glycosylation of various peracetylated bromo sugar with benzyl glycolate using InBr3 as a glycosyl promotor followed by in situ hydrogenolysis of resulting glycosyl ester. A tandem glycosylating and hydrogenolytic activity of InBr3 has been successfully investigated in a one-pot procedure. The resulting synthetically valuable and virtually unexplored class of β-CMGL (glycosyl acids) could serve as an excellent potential chiral auxiliary in the asymmetric synthesis of a wide range of enantiomerically pure medicinally prevalent β-lactams and other bioactive molecules of diverse medicinal interest.

UNSTRUCTURED Billions of people in the world own a smartphone. It is a low-cost, portable computing device with countless features, among which applications stand out, which are programs or software developed to meet a specific goal. A wide range of applications available ranging from entertainment and personal organization to work and education is available currently. It is a vast and profitable market. Health applications have been a means of intervention for different areas, including chronic diseases, epidemics, and health emergencies. A recently published paper in the journal with the highest impact factor in Digital Health (“Journal of Medical Internet Research”) proposes a classification of health applications. This study performs a critical analysis of this organization and presents other sort criteria. This paper also presents and analyzes the “Meu Info Saúde” (“My Health Info”) app – a pioneering government initiative focused on primary care launched by the Oswaldo Cruz Foundation. The application classification proposal that will be presented builds on the intervention strategies in the health-disease process, namely: “Health Promotion”, “Disease Prevention” and “Care, Treatment and Rehabilitation”, as defined by official documents such as the World Health Organization and the Centers for Disease Control and Prevention. Most applications present in the sample are of private and foreign origin, free to download, but with a display of ads or the sale of products and services. The sampled applications were classified as “Health Promotion”, and some applications have also been categorized as “Disease Prevention” or “Care, Treatment or Rehabilitation” because they have multiple functionalities. The applications identified as “Health Promotion” focused only on individuals’ lifestyle and their increased autonomy and self-care management capacity. From this perspective, the apps analyzed in this paper differ from the “Meu Info-Saúde” application developed at Fiocruz.

Way Of Thinking

This is a book about wisdom. It is an inquiry into the beginnings of a particular way of thinking about life in the world. Seen in terms of wisdom, the world is not a meaningless array of disconnected things but something that is experienced as an ordered reality. This holistic way of understanding life in the world characterized pursuits of wisdom in a two-sided classical and biblical tradition that exercised a profound influence on Western culture. This book examines the development of that tradition in a wide range of texts from Homer to Plato and in the writings of early Jewish and Christian authors.
