Full textAbstract:
The processes of globalization of international trade involve the unhindered movement of resources and goods, which is objectively impossible to carry out without maritime transport. Currently, maritime transport provides sustainable foreign economic transport and production relations between individual countries. Sea transportation occupies about 80% of the world’s cargo turnover, and this percentage increases every year. Sea transportation is the most efficient, reliable and economical way of international transportation of most goods. Corporate social responsibility is an integral part of sustainable development of maritime cargo transportation companies and includes care for the environment, labor rights and human rights, business ethics. In 2018, a strategy directed towards reducing annual greenhouse gas emissions from vessels by 2050 by at least 50% of the total volume compared to 2008 was adopted. The article proposes methods for calculating tracking indicators of the sea transport energy efficiency, basic elements of planning the energy efficiency management of the vessel are allocated. The sustainable development strategy of the Danish company Maersk, specializing in maritime freight transportation and port terminal maintenance, envisages four areas - climate change, inclusive trade, food loss and ship recycling. The Maersk’s partners are international organizations that contribute to the implementation of the UN sustainable development strategy. Since 2019 Maersk reports a 42% reduction in relative CO2 emissions compared to 2008. The company plans to jointly develop carbon dioxide fuel types and sustainable fuel solutions with energy suppliers, as well as with technology developers, researchers, investors and other transportation companies and logistics providers. Thus, Maersk is gradually demonstrating a global commitment to the ecologically sustainable logistics in line with its commitment to reducing carbon emissions across the supply chain. Maersk has taken the initiative to abandon the use of fossil fuels and has set a global goal of achieving zero carbon emissions by 2050 in the performance of all its operations.

The Liner services provides regular shipments of goods between ports within the set timeframe. A fixed route, the obligation of receiving cargo and to go to sea with established schedule distinguishes line service from the sea transportation of bulk cargo. Containerization, establishment and improvement of routes and infrastructure helped liner shipping to become the driving force of Global economy, which supports the growth of international trade, development of different business forms such as mainly small and medium sized businesses. The shipment volume of containerized cargo was 37.1 M.TEU in 1994, by 2020 the figure reached up to 143.3 M.TEU. This indicator was growing at a high rate on East-West route during 1990-2016; In terms of North-South, South-South and intraregional route same measure was high between 1990-2004 years. Afterwards, Abovementioned growth has become more stable. Containerization changed the structure of Liner fleet. If general cargo vessels deadweight was growing during 1970-2010 (From 40.5M Dwt to 99.7M Dwt), in the latest 10 years, the tonnage has been decreasing and as for 2020 it was 74.6M Dwt. In exchange for this the number of container ships have been growing consistently and in 2020 it consisted of 274.7M Dwt. Maersk became the largest line operator since 2001 (with a market share of 9.4%) and by 2020 it’s share of the business has grown to 17%. The company owns container terminals worldwide, including the Poti container terminal. MSC is on second place (9.4% market share), COSCO is on third place (12.4%) and CMA CGM takes forth place (11.8%).

Full textAbstract:
Abstract Liner shipping is the most efficient mode of transport for goods. International liner shipping is a sophisticated network of regularly scheduled services that transports goods from anywhere in the world to anywhere in the world at low cost and with greater energy efficiency than any other form of international transportation. Liner shipping connects countries, markets, businesses and people, allowing them to buy and sell goods on a scale not previously possible. Today, the liner shipping industry transports goods representing approximately one-third of the total value of global trade. Ocean shipping contributes significantly to international stability and security. Considering the large and constant struggle in the market in terms of competitive pricing of products, a very important and indispensable role represents the container transport with a clear task to define the final price of the product. This paper analyzes the costs of container transport flow between Far East and Serbia, using different liner shipping services, observing the six world’s largest container operators (Maersk Line, Mediterranean Shipping Company, CMA CGM, Evergreen Line, China Ocean Shipping Company and Hapag-Lloyd) and inland (truck-rail-river) transport corridors. These corridors include distance between selected Mediterranean ports (Koper, Rijeka, Bar, Thessaloniki, Constanta) and Serbia. As a result, in this paper is considered a mathematical model that provides a comparative analysis of transportation costs on the different routes. It is observed already existing transport routes and it is also given hypothetical review to the development of new transport routes. The main goal of this research is to provide an optimal route with lowest transportation cost during container transport. Selection of the best route in the intermodal network is a very difficult and complex task. The costs in all modes of transport and the quality of their services are not constant parameters and changes depending on a number of conditions and characteristics. The analysis of this model within combined maritime and land-based networks would prove helpful for the study of logistics chains, the hinterland-foreland continuum, intermodal transport systems, and market competitiveness.

Full textAbstract:
The sectoral structure of the Northern sea transport corridor is defined, the set of the transport tasks provided to them - the international transit, import and export operations, internal transportations is considered. It is shown that in relation to the water area of the sector of the Northern Sea Route both the international, and internal transportations (big cabotage and intersectoral transportations) can be referred to transit. The analysis of transit transportations across the Northern Sea Route between the countries in 2010-2018 is carried out, dynamics and commodity structure of transit is defined. Dynamics of transit transportations of main types of freights is considered: bulk freights (oil products, gas condensate), bulk cargoes (iron ore, coal). The analysis of dynamics of in-Russian transit transportations across the Northern Sea Route is carried out; dynamics of transportations of frozen fish which transportation the possibility of creation of the year-round container line between the ports of Petropavlovsk Kamchatsky, Murmansk, Arkhangelsk and St. Petersburg contacts is separately considered. Results of development of transit transportations in 2010-2018 are generalized and the factors defining demand of transit transportations of different types of freights are defined. Assessment of prospects of development of transit freight traffic by foreign shipping companies (Maersk) is given. The conclusion is drawn that a priority of development of navigation in the sector of the Northern Sea Route is providing national investment projects - transportations of mineral resources and ensuring activity of mining companies. At the same time, creation of a steady system of transportation of the Arctic mineral resources defines problems of development of icebreaking, navigation and hydrometeorological providing that will lead to reduction of risk of the Arctic navigation and will increase appeal of the sea Arctic transport system in general. It is defined that emergency conditions for development of navigation in the water area of the Northern Sea Route are: expansion of group of the domestic Arctic linear icebreaker fleet; central planning of sea freight transportation and coordination of actions of participants which could increase appeal of use of the Northern Sea Route including for transit transportations.

Full textAbstract:
abstractIn 1964, Block 29/7 was awarded as part of the first licencing round to Shell and Esso (UK). The Curlew area comprises a series of terraces that step down from the Western Platform into the West Central Graben. Exploration drilling started in 1977 but it wasn't until 1990 that well 29/7-4 successfully tested a 100 ft column of undersaturated volatile oil in the Upper Jurassic Fulmar Formation sandstones. Further exploration drillng, aided by 3D seismic data (acquired in 1991), yielded additional discoveries: Curlew C (1993, oil) and Curlew D (1994, condensate-rich gas). In Curlew D new technologies were succesfully applied to described and evaluate the isolated hanging wall compartment. Oil was discovered in what is now called Curlew D South in February 2000.Hydrocarbon accumulations in the Curlew area occur in dip-closed faulted anticlinal structures. The producing Upper Jurassic Fulmar Formation is a heterogeneous mix of bioturbated shallow marine sandstones. barrier sandstones, and lagoonal/swamp deposits. The range in reservoir quality is reflected in the field porosity (5-27%) and permeability (0.001-800 mD). Reservoir compartments in the field (curlew B, D, and D South) are controlled by complex reservoir architecture, structure and fault geometry. Each reservoir compartment is characterized by a different fluid contact and a distinct fluid type. The reservoir heterogencity provieds potential for bypassed hydrocarbons in undrilled compartments, as was proven by the Curlew D South development.Curlew B, D, and D South have since been developed. Evacuation of hydrocarbons from the Curlew area is via the Maersk Curlew FPSO, to which the producing wells have been tied back. Gas is fed nto the Fulmar Gas Line and oil is taken onshore by shuttle tankers. The initially-in-place volume in Curlew B at standard conditions is 24 MMSTB of oil and 25 BSCF of solution gas. Curlew B was developed via horizontal well 29/7-10y and came on stream in November 1997 at a rate of about 23 000 STB/D. The initially-in-place volume in Curlew D is 340 BSCF of gas and 100 MMSTB of condensate. Curlew D was developed via two vertical wells, 29/7-8z and 29/7-9, and started production in February 1998 with production rates up to 115 MMSCF/D of gas and 34 000 STB/D. Gas production from the field is constrained. however, by the facilities. Curlew D South is developed by the vertical well 29/7-11 which came on stream in March 2000 after a North Sea record-time tie back of the original appraisal well.

Angola Opens Congo, Kwanza Blocks in Ongoing Bid Round Angola’s National Oil, Gas, and Biofuel’s Agency has opened blocks for licensing in the Onshore Lower Congo Basin and the Onshore Kwanza Basin as part of its 2020 oil and gas licensing round. This latest call to tender is part of the agency’s ongoing 2019–2025 hydrocarbons licensing strategy. The Onshore Lower Congo Basin Blocks include CON1, CON5, and CON6; while the Onshore Kwanza Basin Blocks comprise KON5, KON6, KON8, KON9, KON17, and KON20. The round aims to expand research and evaluation activities across sedimentary basins, increase geological knowledge of Angola’s hydrocarbon potential, and invite a new wave of explorers to yield new discoveries. Raven Field Startup for BP in Egypt Natural gas has begun flowing from the BP-operated Raven field, the third stage of the company’s major West Nile Delta (WND) development off the Mediterranean coast in Egypt. The $9-billion WND development includes five gas fields across the North Alexandria and West Mediterranean Deepwater offshore concession blocks in the Mediterranean Sea. Raven is currently producing approximately 600 MMcf/D with a peak potential of 900 MMcf/D and 30,000 B/D of condensate. Raven follows the Taurus/Libra and Giza/Fayoum projects, which started production in 2017 and 2019, respectively. It produces gas to a new onshore processing facility, alongside the existing WND onshore processing plant. In total, the WND development includes 25 wells producing gas to the onshore processing plant via three long-distance subsea tiebacks. The onshore facilities—including the new Raven facility—now have a total gas processing capacity of around 1.4 Bcf/D of gas. All gas produced is fed into Egypt’s national grid. BP is the operator and has an 82.75% stake in the WND development, with Wintershall Dea holding the remaining 17.25% interest. CGX Secures Rig for Kawa-1 Well off Guyana CGX Energy and Frontera Energy, joint venture partners in the Petroleum Prospecting License for the Corentyne block offshore Guyana, have secured semisubmersible Maersk Discoverer to drill the Kawa-1 well. An early third quarter spud for the exploration well is targeting a Santonian age, stratigraphic trap, interpreted to be analogous to the discoveries immediately to the east on Block 58 in Suriname. The well is anticipated to be drilled to a total depth of approximately 6500 m in a water depth of approximately 370 m. The contract has an estimated duration of 75–85 days and has a one-well option attached. If exercised, that probe would spud in the nearby Demerara Block and take an estimated 40 days to reach its target. Talos’ Bulleit Reservoir in US Gulf Smaller Than Expected A technical assessment of the main producing sand performance at Talos Energy’s Green Canyon Block 21 Bulleit field in the US Gulf has indicated a smaller reservoir than originally anticipated. Project partner Otto Energy said the assessment included detailed bottomhole pressure and reservoir performance data collected after hookup and first production. The Block 21 field is flowing via a single subsea well tied back to a platform in nearby Green Canyon Block 18. While additional technical work is ongoing, the currently favored path forward is to move away from the current sand and execute a recompletion of the well in the shallower DTR-10 sand. A DTR-10 recompletion will require the procurement of long-lead items from manufacturers, which are expected to cost $3.5 million with payment expected in mid-2021. The recompletion is expected to begin in mid-2022, with production from the DTR-10 immediately following in mid-to late 2022. Captain Field EOR Stage 2 Project a Go Ithaca Energy, operator of the Captain field, has sanctioned the Captain Enhanced Oil Recovery (EOR) Stage 2 project in the UK Central North Sea after receiving Field Development Plan Addendum consent from the Oil and Gas Authority. EOR Stage 2 is designed to significantly increase hydrocarbon recovery by injecting polymerized water into the reservoir through additional subsea wells, subsea infrastructure, and new topsides facilities. Stage 1 of the project demonstrated that polymer EOR technology can work, with the production response in line with or better than expected across all injection patterns, helping maximize economic recovery. The Captain field was discovered in 1977, in Block 13/22a located on the edge of the outer Moray Firth. The billion-barrel field achieved first production in March 1997—over 24 years ago. Ithaca Energy holds 85% working interest, while partner Dana Petroleum holds the remaining 15%. Equinor Touts new Tyrihans Field Discovery Equinor and partners Total E&P Norge AS and Vår Energi AS have struck oil and gas in a new segment belonging to the Tyrihans field in the Norwegian Sea. Exploration well 6407/1-A-3 BH in production license 073 was drilled from sub-sea template A at Tyrihans North. The well was drilled to a measured depth of 5332 m by semisubmersible drilling rig Transocean Norge and struck a gas column of about 43 m and an oil column of about 15 m in the Ile formation, including about 76 m of moderate to good reservoir quality sandstone. In the Tilje formation, moderate to good quality water-bearing reservoir was struck. The Tyrihans field is in the middle of the Norwegian Sea, some 25 km southeast of the Åsgard field and 220 km northwest of Trondheim. The licensees consider the discovery commercial and intend to start production immediately. Recoverable resources are so far estimated at between 19 and 26 million BOE. Maersk Awarded Intervention Work off Brazil Maersk Drilling has been awarded a contract with Karoon Energy Ltd. for the semisubmersible rig Maersk Developer to perform well intervention on four wells at the Baúna field offshore Brazil. The contract is expected to begin in the first half of 2022, with a firm duration of 110 days. The value of the contract is $34 million, including rig modifications and a mobilization fee. The contract contains options to add up to 150 days of drilling work at the Patola and Neon fields. Carnarvon Completes Farmout of Buffalo Project Carnarvon Petroleum has completed the farmout of 50% of the Buffalo project to Advance Energy PLC. On 17 December 2020, Carnarvon announced that Advance Energy would acquire 50% of the Buffalo project off the west coast of Australia by funding the drilling of the Buffalo-10 well up to $20 million on a free carry basis. Advance met this funding requirement and now has a 50% interest in the project. The well is on track to be drilled in late 2021, subject to securing a drilling rig, where the tendering process is already underway. Following the well, the joint venture will acquire development funding from third-party lenders and any additional funding will be provided by Advance as an interest-free loan. The current plan is to suspend a successful well as a future producer and begin early development studies during 2021. Shell Hires Seadrill Rig for Brazilian Campaign Shell has contracted Seadrill’s drillship West Tellus for a new drilling campaign offshore Brazil this year. The program is expected to start in BC-10 of the Campos Basin, where Shell operates the Parque das Conchas made up of the Abalone, Argonauta, and Ostra fields. BC-10 has produced more than 100 million bbl since oil first started flowing from the block in 2009. The drillship will be used on the third phase of BC-10 activity, which includes five additional production wells and two water-injection wells at the Massa and Argonauta O-Sul fields, with the wells connected to the Espirito Santo FPSO. Shell owns a 50% operating stake in BC-10. India’s ONGC retains a 27% minority share and Qatar Petroleum the remaining 23%. Following the BC-10 work, the operator is expected to drill the first wells in the Campos Basin’s C-M-791 block, which was acquired during the 15th bid round held in 2017. Shell owns a 40% operating stake in the block, with Chevron retaining a 40% interest and Portugal’s Galp Energia the remaining 20%. Panoro Energy Kicks Off 2021 Drilling Campaign Offshore Gabon Panoro Energy has initiated its 2021 Gabon drilling campaign with the spudding of the Hibiscus Extension well on the Dussafu Marin Permit. That well will be followed by drilling at Tortue and Hibiscus North. Hibiscus and Tortue are two out of a total of six discovered fields within the Dussafu Permit offshore Gabon. Panoro currently holds a 7.5% interest in the license and has entered into an agreement to acquire an additional 10% working interest in the Dussafu Permit, bringing its total ownership to 17.5% following completion of the transaction. The Extension well is being drilled with the jackup Borr Norve and is the first well in a three-well campaign planned on Dussafu during 2021. The well is planned as a vertical well to test structure, oil, and reservoir presence in what is believed to be a possible northerly extension of the Gamba reservoir in the Hibiscus field. The well is positioned about 3 km northwest of the Hibiscus discovery well drilled by the joint venture in 2019. The initial well and its appraisal sidetrack established a 2P gross recoverable reserves of just over 46 million bbl at the Hibiscus field. The Extension well is expected to take around 30 days to drill and log to a total depth of 3500 m. Success at the probe could prompt one or two appraisal side-tracks to further delineate the field. Following the Hibiscus Extension, the rig will move to drill a horizontal production well, DTM-7H, at the Tortue field. This will complete the Phase 2 development of Tortue and, along with DTM-6H, will bring the total number of production wells at Tortue up to six. An exploration well at the Hibiscus North prospect, located approximately 6 km north-northeast of the initial Hibiscus well is also scheduled. Hibiscus North is a separate 10–40 million bbl prospect that could be tied into the Hibiscus/Ruche development project. Puma West Strike for BP in the US Gulf An exploration well at the Puma West prospect in the deepwater US Gulf has yielded a significant oil discovery for operator BP. The well, on Green Canyon Block 821, was drilled using Seadrill drillship West Auriga to a total depth of 23,530 ft and encountered oil pay in a high-quality Miocene reservoir with fluid properties like productive Miocene reservoirs in the area. Preliminary data supports the potential for a commercial volume of hydrocarbons. The Puma West partners will begin planning an appraisal program to better define the discovered resource. The discovery well has been suspended as a keeper well to preserve future utility. Puma West is located west of the BP-operated Mad Dog field and is approximately 131 miles off the coast of Louisiana in 4,108 ft of water. The Puma West is operated by BP with a 50% working interest. Partners include Chevron with 25% and Talos Energy with the remaining 25%. Petrobras Pushes First Oil at Mero Into 2022 Petrobras has postponed first oil from its Mero 1 field via the FPSO Guanabara in the Santos Basin offshore Brazil due to delays with the production system. Startup at Mero 1 was originally expected in the fourth quarter of this year and is now expected to begin flowing during the first quarter of 2022 due to COVID-19 pandemic-related delays with the buildout of the production system in China. The FPSO will be installed in the Mero field, which belongs to the Libra Block, in the Santos Basin pre-salt area, with a processing capacity of 180,000 OPD. The field is operated by Petrobras (40%) in partnership with Shell Brasil Petróleo (20%), Total E&P (20%), CNODC Brasil Petróleo e Gás (10%), CNOOC Petroleum Brasil (10%), and Pré-Sal Petróleo, which is the contract manager.

Full textAbstract:
Leukocyte rolling, adhesion, and migration on vascular endothelium involve several sets of adhesion molecules that interact simultaneously. Each of these receptor-ligand pairs may play multiple roles. We examined the role of ICAM-1 in adhesive interactions with mouse aortic endothelial cells (MAECs) in an in vitro flow system. Average rolling velocity of the monocytic cell line WEHI 274.1 was increased on ICAM-1-deficient MAECs compared with wild-type MAECs, both with and without TNF-α stimulation. High-temporal-resolution analysis provided insights into the underlying basis for these differences. Without TNF-α stimulation, average rolling velocity was slower on wild-type than on ICAM-1-deficient endothelium because of brief (<1 s) pauses. On TNF-α-stimulated ICAM-1-deficient endothelium, cells rolled faster because of transient accelerations, producing “jerky” rolling. Firm adhesion to ICAM-1-deficient MAECs was significantly reduced compared with wild-type MAECs, although the number of rolling cells was similar. These results demonstrate directly that ICAM-1 affects rolling velocity by stabilizing leukocyte rolling.

The idea of engaging in publishing activities came to the brothers Sabashnikov in spring 1889 at the meeting with their teacher of natural science P. Mayevsky. In summer Peter Maevsky arrived in the estate Kostino of Vladimirskaya province to prepare his work “Zlaki sredney Rossii” for the publication. From that time and till 1917 Kostino became a place of work and rest for many who cooperated with the publishing house of the brothers Sabashnikov. This article is devoted to little known pages of living and social activities of Mikhail and Sergei Sabashnikov in the estate Kostino of Vladimirskaya province (1889-1917).

AbstractThis paper begins by tracking the history of piracy from Greek and Roman times, to the Golden Age of piracy, into modern day. It also looks at the motivations for becoming a pirate and the “piracy cycle.” The paper then moves into a discussion of how piracy has influenced the law, such as its impact on Universal Jurisdiction and international treaties like the UN Convention on the Law of the Sea; however, a stable definition of what constitutes “piracy” has become troublesome, even with the abundance of legal sources related to the subject. The paper then moves into a discussion of three US court cases dealing with the issue of piracy: the first from the Golden Age of piracy, the second in the early part of this century showing how piracy is not always prosecuted in the traditional sense, and finally with the case of the famous pirate the US Navy SEALS captured during the rescue of Captain Richard Phillips of the Maersk Alabama. Finally, the paper concludes the discussion using the modern day situation of Somalia to show how the “piracy cycle” is still capable of explaining what draws people to piracy, how that particular situation has been combated by the international community, and how neighboring countries, like Kenya, are using their own court systems to the advantage of the rest of the world.

AbstractWe show that metric abstract elementary classes (mAECs) are, in the sense of [15], coherent accessible categories with directed colimits, with concrete ℵ1-directed colimits and concrete monomorphisms. More broadly, we define a notion of κ-concrete AEC—an AEC-like category in which only the κ-directed colimits need be concrete—and develop the theory of such categories, beginning with a category-theoretic analogue of Shelah’s Presentation Theorem and a proof of the existence of an Ehrenfeucht–Mostowski functor in case the category is large. For mAECs in particular, arguments refining those in [15] yield a proof that any categorical mAEC is μ-d-stable in many cardinals below the categoricity cardinal.

Full textAbstract:
The distribution, abundance and feeding behaviour of sea urchins (Paracentrotus lividus, Psammechinus miliaris, Sphaerechinus granularis) and the macro-algal biomass were assessed in two maerl beds within a north-east Atlantic coastal ecosystem (Bay of Brest, Brittany, France). To study the possible control of herbivorous sea urchins on the macrophytic algae, one maerl bed under the influence of urban sewage (northern site) was compared to one less influenced by urban and industrial outlets (southern site). Macrophytic biomass in the northern site was estimated as 40-fold higher than in the southern site where sea urchins were, on average, 38-times more numerous. Preliminary results support the hypothesis that grazing of sea urchin, even in low densities, can be a factor regulating the macrophytic biomass on maerl beds except in too nutrient enriched environments. So in the northern basin of the Bay, data pointed out the role of anthropogenic impacts on macrophytic biomass increase which was concomitant with the progressive disappearance of sensitive herbivorous species like sea urchins, both processes result in change in the ecosystem.

Full textAbstract:
The purpose of this work is to evaluate the impact that the Master-level course in Socioemotional Learning for Personal and Social Development (hereinafter MAESE) has had on socioemotional skills, positive psychology (dispositional optimism and satisfaction with life), the level of communicative and teamwork skills developed through coaching, and the capacity for entrepreneurship and innovation in the students of four consecutive graduating classes. This Master-level course has been taught at the University of Zaragoza in a blended-instruction form since 2014 and is currently in its sixth year. The methodology used here is eminently quantitative through an ex post facto descriptive study, although in the coaching and entrepreneurship block, qualitative information is also collected through open-ended questions. The results show that after completing the MAESE, there are few significant improvements in socioemotional skills (MSCEIT). On the other hand, there are significant improvements in the participants’ dispositional optimism (Life Orientation Test), satisfaction with life (SWLS), skill development through coaching, and ability to undertake projects and to innovate (PTWS). We conclude by reinforcing the importance of and responsibility to evaluate the impact that university training has on its students, especially for degrees covering emotion-related content.

Sebuah karya sastra adalah produk kreativitas seorang pengarang dalam memandang kehidupan dan lingkungan sosial ketika karya tersebut diperkenalkan. Dalam proses kreatifnya, seorang pengarang melakukan kerja keras dan serius dalam berbagai dimensi kehidupan dengan realisasi estetiknya dan berujung pada proses imajinatif, kontemplatif, reaktif, reflektif, dan refraktif. Ini dilakukan untuk merepresentasikan karya-karya sastra pengarang. Oleh karena itu, estetika diinternalisasikan ke dalam karya-karya sastra beserta genrenya. Masalah estetika sastra adalah aspek menarik untuk diteliti karena mewarisi gagasan kontemporer mengenai simbol dan pengalaman estetik dengan sifat uniknya. Dalam perjalanan kontemplasinya, seorang pengarang terkadang dihadapkan pada sebuah kontradiksi antara konvensi dan kreasi yang membuat pembacanya terkejut. Fenomena yang hampir sama terjadi dalam novel berjudul Nayla karya Djenar Maesa Ayu. Dalam novel ini, pengarang memiliki semacam kesensitifan untuk menghadapi sebuah objek dan kemampuan untuk menyerap makna keindahan. Keindahan tersebut ditata dengan menghubungkan sifat subjek dan objek melalui keterampilan dalam menata dan mengombinasikan bahasa. Itulah cara bagaimana seorang pengarang bekerja dalam koridor estetika untuk mengekspos konflik, perjuangan, dan dominasi dalam teks sastra.
Abstract:
A literary work is an author creativity product in seeing life and social environment in the time when the work is introduced. In his creative process, an author performs a hard and serious work on various life dimensions with their esthetic realization that ends in the imaginative, contemplative, reactive, reflective, and refractive process. This is done to represent the author’s literary works. Therefore, esthetics is internalized in the literary works along with their genres. The issues on esthetics in literature are interesting aspects to investigate since they inherit contemporary ideas pertaining to symbols and esthetic experience with its unique features. In his journey of contemplation, an author is sometimes confronted with a contradiction between convention and creation that makes the readers get surprised. Almost similar phenomenon takes place in the novel entitling Nayla written by Djenar Maesa Ayu. In this novel, the author has a kind of sensitivity to face an object and ability to absorb the sense of beauty. The beauty is arranged by relating the nature of subject and object through the skills in arranging and combining languages. That is the way how an author works in esthetic corridor to expose conflicts, struggles, and domination in literary texts.
Keywords: creative process, esthetics, reality of subject and object

Background: Medication administration errors (MAEs) occur in health care settings however, the types, contributing factors to MAEs and barriers to reporting are not well studied in Rwandan context.Methods: Quantitative approach was adopted. Descriptive cross-sectional design was used. A convenience sampling was used to select 151 nurses working in the paediatric units of the selected teaching hospitals in Rwanda. Pre-tested questionnaire for validity and reliability was used to collect data. Data was coded and entered into SPSS version 21. Descriptive statistics and inferential statistics (Chi-square test) were used to analyze data.Results: Approximately 33.6% of the participants were able to identify one type, 17.4 % two, 18.1% three, 17.4% four types, 10.7% six types and only 2.7% identified all the seven MAEs. Identified main contributory factor to MAEs was the heavy workload it like this-Identified main contributory factor to MAEs was the heavy workload [82 (55%)]. The main barrier to self-reporting was fear to be blamed if something happens to the patient as a result of the medication administration error (88 (59.1%)). All the socio demographic were associated with the types of MAEs committed by participants. In addition, the experience, marital status and job position of the participants were significantly associated with factors contributing to MAEs (p= .001, p=.000 and p= .044) respectively whereas all the socio demographic were significantly associated with barriers to self reporting.Conclusions: Factors contributing to MAEs were found in both parties and barriers to self-reporting were identified to be the fear reasons and administrative reasons. Therefore, the heavy workload should be addressed to reduce MAEs and a non-punitive environment is imperative in encouraging self-reporting of MAEs.

Full textAbstract:
Magnetoactive elastomers (MAEs) claim a vital place in the class of field-controllable materials due to their tunable stiffness and the ability to change their macroscopic shape in the presence of an external magnetic field. In the present work, three principal geometries of shear deformation were investigated with respect to the applied magnetic field. The physical model that considers dipole-dipole interactions between magnetized particles was used to study the stress-strain behavior of ellipsoidal MAEs. The magneto-rheological effect for different shapes of the MAE sample ranging from disc-like (highly oblate) to rod-like (highly prolate) samples was investigated along and transverse to the field direction. The rotation of the MAE during the shear deformation leads to a non-symmetric Cauchy stress tensor due to a field-induced magnetic torque. We show that the external magnetic field induces a mechanical anisotropy along the field direction by determining the distinct magneto-mechanical behavior of MAEs with respect to the orientation of the magnetic field to shear deformation.

Full textAbstract:
Passage of apolipoprotein B-containing lipoproteins (apoB-LPs), i.e., triglyceride-rich lipoproteins (TRLs), intermediate-density lipoproteins (IDLs), and low-density lipoproteins (LDLs), through the endothelial monolayer occurs in normal and atherosclerotic arteries. Among these lipoproteins, TRLs and IDLs are apoE-rich apoB-LPs (E/B-LPs). Recycling of TRL-associated apoE has been shown to form apoE-carrying high-density lipoprotein (HDL)-like (HDLE) particles in many types of cells. The current report studied the formation of HDLE particles by transcytosis of apoB-LPs through mouse aortic endothelial cells (MAECs). Our data indicated that passage of radiolabeled apoB-LPs, rich or poor in apoE, through the MAEC monolayer is inhibited by filipin and unlabeled competitor lipoproteins, suggesting that MAECs transport apoB-LPs via a caveolae-mediated pathway. The cholesterol and apoE in the cell-untreated E/B-LPs, TRLs, IDLs, and LDLs distributed primarily in the low-density (LD) fractions (d ≤ 1.063). A substantial portion of the cholesterol and apoE that passed through the MAEC monolayer was allotted into the high-density (HD) (d > 1.063) fractions. In contrast, apoB was detectable only in the LD fractions before or after apoB-LPs were incubated with the MAEC monolayer, suggesting that apoB-LPs pass through the MAEC monolayer in the forms of apoB-containing LD particles and apoE-containing HD particles.

Data dikumpulkan mclalui teknik dokumentasi dan dianalisis secara deskriptif. Berdasarkan analisis data, dapat disimpulkan bahwa Nayla adalah sebuah novel dengan pengarang yang secara sadar ingin memperjuangkan hak-hak perempuan, terutama yang berkaitan dengan seksualitas. Tokoh pcrempuan dalam Naylai adalab seorang perempuan superior, bukan inferior, seorang perempuan yang 'mendominasi' laki-laki, bukan yang 'didominasi' oleh laki-laki. Pengarang juga berusaha untuk mengangkat posisi perempuan dengan menghadirkan seorang karakter perempuan yang menemukan kesadaran akan eksistensi diri, menyadari makna kebidupan dan hidup. Para tokohnya adalah perempuan- perempuan profesional yang bahkan dapat disejajarkan dengan para laki-laki. Mereka adalah tokoh perempuan yang jarang mengurusi urusan rumah tangga Terkait dengan seksualitas, sang tokoh (si pengarang) berpendapat bahwa perempuan tidak selayaknya diperlakukan sebagai objek semata, retapi seharusnya juga memiliki kesempatan untuk bersenang-senang dan disenangkan.
Abstract:
This research aims to describe objectively the representation of feminism in the novel Nayla by Djenar Maesa Ayu. The research data are speeches, actions, and happenings experienced by the main character. The source of the data was the novel Nayla by Djenar Maesa Ayu second edition published by Gramedia in 2005. The data were collected through documentation technique and analyzed descriptively. Based on the analysis of the data, it could be concluded that Nayla was a novel whose author consciously wished to struggle for women rights, especially those related to sexualities. The female character in Nayla is a superior woman, not an inferior one; a female who 'dominates' males, not the one who 'is dominated' by males. 'The author also strives to raise women's positions by presenting a female character who has found a consciousness of self-existence, realized the meanings of life and living. The characters are professional women who can even be equalized with men. 'They are female characters who seldom take care of domestic households. Related to sexualities, the character (the author) has the opinion that women should not have been treated as objects only, but should also have been given opportunities to enjoy themselves and to be spoiled.

Research Highlights: The developed National Set of Indicators for the Mapping and Assessment of Ecosystems and their Services (MAES) implementation in Greece at the national level sets the official, national basis on which future studies will be conducted for MAES reporting for the achievement of targets within the National and the European Union (EU) biodiversity Strategy. Background and Objectives: Greece is currently developing and implementing a MAES nation-wide program based on the region’s unique characteristics following the proposed methodologies by the European Commission, in the frame of the LIFE-IP 4 NATURA project (Integrated actions for the conservation and management of Natura 2000 sites, species, habitats and ecosystems in Greece). In this paper, we present the steps followed to compile standardized MAES indicators for Greece that include: (a) collection and review of the available MAES-related datasets, (b) shortcomings and limitations encountered and overcome, (c) identification of data gaps and (d) assumptions and framework setting. Correspondence to EU and National Strategies and Policies are also examined to provide an initial guidance for detailed thematic studies. Materials and Methods: We followed the requirements of the EU MAES framework for ecosystem services and ecosystem condition indicator selection. Ecosystem services reported under the selected indicators were assigned following the Common International Classification of Ecosystem Services. Spatial analysis techniques were applied to create relevant thematic maps. Results: A set of 40 MAES indicators was drafted, distributed in six general indicator groups, i.e., Biodiversity, Environmental quality, Food, material and energy, Forestry, Recreation and Water resources. The protocols for the development and implementation of an indicator were also drafted and adopted for future MAES studies in Greece, providing guidance for adaptive development and adding extra indicators when and where needed. Thematic maps representing ecosystem services (ES) bundles and ES hotspots were also created to identify areas of ES importance and simultaneously communicate the results at the national and regional levels.

Jersey Oil and Gas Unearths Wengen Prospect The Greater Buchan Area (GBA) now has four drill-ready prospects to add to discoveries already slated for development. In a new subsurface evaluation, Jersey Oil & Gas, a British-independent North Sea-focused upstream oil and gas company, has uncovered a new prospect, named Wengen, to complement its Verbier Deep, Cortina NE, and Zermatt drill-ready prospects. The four are estimated to host some 222 million bbl of P50 prospective resources, all in the immediate vicinity of Jersey’s planned GBA production facility. The consolidated Greater Buchan venture comprises Buchan field (80 million bbl), Verbier (c25 million bbl), J2 (c20 million), and Glenn (14 million). The new prospect, located in License P2170, is directly west of the Tweedsmuir field and should host some 62 million bbl of potential resources (P50), with the probabilistic range set at 31 million bbl at P90 (higher confidence) and 162 mil-lion for P10 (lower confidence). Probability of geological success is 22% for the prospect. Contractor Rockflow previously estimated the recoverable resources in the GBA at 94.7 million bbl, including the parts within P2170. In late November, Jersey announced it is taking full ownership of License P2170, which hosts most of the Verbier discovery, as part of the GBA. In March, Jersey told investors the project is fully funded and that it intends to take the project to potential industry partners via a farm-out process. An exploratory drilling campaign is being planned for 2022. Jordan Finds “Promising” Gas Reserves Near Iraq Border Jordan’s majority state-owned National Petroleum Company (NPC) has discovered “promising” natural gas in the Risha gas field along its eastern border with Iraq. Risha makes up nearly 5% of the kingdom’s consumption of natural gas of around 350 MMcf/D for power generation, Jordanian officials said. The flow of new gas supplies will raise the productivity of the gas field and help Jordan cut dependence on oil imports to fuel its power sector and industries. The country, which now imports over 93% of its total energy supplies, is burdened by a $3.5-billion annual bill, comprising almost 8% of Jordan’s GDP. Although British supermajor BP abandoned the eastern desert area in 2014 after investing over $240 million, Jordanian exploration has stepped up since 2019, boosting quantities by at least 70%, Mohammad al Khasawneh, head of NPC, said. An ambitious 10-year energy plan unveiled in 2019 aims to secure nearly half of the country’s electricity generation from local energy sources com-pared to a current 15%, according to Iraq Energy Minister Hala Zawati. The plan is meant to diversify local energy sources by expanding investments in renewable and oil shale to reduce costly foreign fuel imports, Zawati added. ExxonMobil Discovers Hydrocarbons Offshore Suriname ExxonMobil and Petronas have discovered several hydrocarbon-bearing sandstone zones with good reservoir qualities in the Campanian section of the Sloanea-1 exploration well on Block 52 offshore Suriname, adding to ExxonMobil’s finds in the Guyana-Suriname basin. The well was drilled by operator Petronas. ExxonMobil said in November that it is prioritizing near-term capital spending on advantaged assets with the highest potential future value. Maersk Drilling reported in early July that it had secured the Maersk Developer from Petronas subsidiary PSEPBV in a $20.4-million one-well exploration con-tract offshore Suriname. The semisubmersible rig drilled the Suriname-Guyana basin well to a total depth of 15,682 ft. “We are pleased with the positive results of the well,” Emeliana Rice-Oxley, Petronas’ vice president of upstream exploration, said. “It will provide the drive for Petronas to continue exploring in Suriname, which is one of our focus basins in the Americas.” Block 52 covers an area of 1.2 million acres and is located approximately 75 miles offshore north of Paramaribo. The water depths on Block 52 range from 160 to 3,600 ft. ExxonMobil E&P Suriname BV, an affiliate of ExxonMobil, holds 50% interest in Block 52. PSEPBV is operator and holds 50% interest. CNOOC Starts Production on Penglai 25-6 Oil Field Area 3 Project China National Offshore Oil Corporation (CNOOC) announced on 14 December that its Bohai Sea Project - the Penglai 25-6 oil field area 3 - has started production ahead of schedule. The biggest offshore oil field and the second biggest oil field in China, the Penglai is located in the south central Bohai Sea, with average water depth of about 27 m. In addition to fully utilizing the existing processing facilities of Penglai oil fields, the project has built a new wellhead platform and plans 58 development wells, including 38 production wells and 20 water-injection wells. The project is expected to reach its peak production of approximately 11,511 B/D of crude oil in 2023. Six successful appraisal wells were also drilled, which confirmed the presence of hydrocarbons in reservoirs located with-in Miocene, Lower Minghuazhen, and Guantao sandstones. The Penglai 19-3 oil field is located in Block 11/05 of Bohai Bay, approximately 235 km southeast of Tanggu. The production-sharing contract for block 11/05 was signed between CNOOC and ConocoPhillips China (COPC) in December 1994; the field was discovered jointly by CNOOC and COPC in 1999. The oil field was developed in two phases. Phase I production started in December 2002; production from the wellhead platform C, which is tied back temporarily to the production facilities of Phase I, began in June 2007. Since June 2020, CNOOC has announced five production startups: the Jinzhou 25-1 oilfield 6/11 area project, the Liuhua 16-2 oilfield/ 20-2 oil-field joint development project, the Nan-bao 35-2 oilfield S1 area project, the Luda 21-2/16-3 regional development project, and the Qinhuangdao 33-1S oilfield phase-I project. In Q3 2020, CNOOC achieved a total net production of 131.2 million BOE, which the company said represented an increase of 5.1% year over year. Production from China was said to have increased by 10.4% year over year to 88.6 million BOE. In November, CNOOC revealed that the Liuhua 29-1 gas field had begun production; in September, the company said the Bozhong 19-6 condensate gas field pilot area development project had also begun. Operator CNOOC holds 51% interest while COPC holds 49% interest in the Penglai 25-6 oilfield area 3 project. Equinor’s Snorre Expansion Project Starts Ahead of Schedule, Below Cost Work began in December on the Snorre Expansion Project in the southern part of the Norwegian Sea. This increased-oil-recovery project will add almost 200 million bbl of recoverable oil reserves and help extend the productive life of the Snorre field through 2040. The expansion project is proposed in blocks 34/4 and 34/7 of the Tampen area, approximately 124 miles west of Florø in the Norwegian North Sea. “I am proud that we have managed to achieve safe startup of the Snorre Expansion Project ahead of schedule in such a challenging year as 2020. In addition, the project is set to be delivered more than NOK 1 billion below the cost estimate in the plan for development and operation,” Geir Tungesvik, Equinor’s executive vice president for technology, projects, and drilling, said. Originally scheduled to come onstream in the first quarter of 2021, the project comprises 24 new wells divided into six subsea templates, drilled to recover the new volumes. Bundles connecting the new wells to the platform have been installed, in addition to new risers. The project also includes a new module and modifications on Snorre A. In December 2017, Equinor submitted a modified plan for development and operation of the field. With the expansion, the recovery factor will increase from 46 to 51%, representing significant value for a field with 2 billion bbl of recoverable oil reserves. Wind power will supply about 35% of the power requirement for the Snorre and Gullfaks fields. The Hywind Tampen project, featuring 11 floating wind turbines, should start up in Q3 2022. The investments in the expansion project total NOK 19.5 billion (2020 value). The project has had substantial spin-off effects for the supply industry in Norway, particularly in eastern Norway and in Rogaland. The Snorre field partnership comprises Equinor (operator) 33.27%, Petoro 30%, Vår Energi 18.55%, Idemitsu 9.6%, and Wintershall Dea 8.57%. Petrobras To Sell Entire Stake in Onshore Field of Sergipe Petrobras on 11 December signed a contract with Energizzi Energias do Brasil to sell its entire stake in the onshore field of Rabo Branco, located south of the Carmópolis field in the Sergipe-Alagoas Basin, Sergipe state. The Rabo Branco field is part of the BT-SEAL-13 concession. The $1.5-million sale is in line with Petrobras’ strategy to cut costs and improve its capital allocation, to focus its resources increasingly on deep and ultradeep waters. The average oil production of the field, from January to October 2020, was 138 B/D. Energizzi Energias do Brasil will own 50% stake in the Rabo Branco field; operator Produção de Óleo e Gás (Petrom) holds the remaining 50%. On 10 December, Petrobras closed the divestiture of its full ownership in four onshore fields at the Tucano Basin site in the state of Bahia. Petrobras sold its entire interest to Eagle Exploração de Óleo e Gás (Eagle). Petrobras earned $2.571 million from this sale, in addition to the $602,000 that the company received at the time of signing the sale contract, for a total of $3.173 million. BP, Reliance Announce First Gas From Asia’s Deepest Project Oil-to-telecom conglomerate Reliance Industries Limited (RIL) and BP have started production from India’s first ultradeepwater gas project, the first of three such projects in the KG D6 block. The R Cluster gas field is located off the east coast of India, about 60 km from the existing KG D6 control-and-riser platform (CRP), and comprises a subsea production system tied back to the CRP via a subsea pipeline. It is the deepest offshore gas field in Asia at a depth greater than 2000 m. The companies’ next project, the Satellites Cluster, is expected to come on stream this year, followed by the MJ project in 2022. These projects will utilize the existing hub infrastructure in the KG D6 block. “Growing India’s own production of cleaner-burning gas to meet a significant portion of its energy demand, these three new KG D6 projects will support the country’s drive to shape and improve its future energy mix,” BP Chief Executive Bernard Looney said. The R Cluster field is expected to reach plateau gas production of about 12.9 million standard cubic meters per day (MMscm/D) in 2021. Peak gas production from the three fields should be 30 MMscm/D (1 Bcf/D) by 2023, about 25% of India’s domestic production, and will help reduce the country’s dependence on imported gas. RIL is the operator of KG D6 with a 66.67% interest; BP holds a 33.33% participating interest.

The surveys to different localities of Himachal Pradesh, Jammu & Kashmir and Uttarakhand yielded three species of genus Sphrageidus Maes, namely S. similis (Fuessly), S. simlensis (Gupta) and S. xanthorrhoea (Kollar) of subfamily Lymantriinae. The external morphological characters particularly wing maculation and venation along with genitalia characteristics have been studied and illustrated in detail. The male genitalic features like distinct saccus, ring-like juxta, simple valva, aedeagus with a hook or reversed spine at the apex and distinct wing venation, i.e., absence of vein M2 in hindwing completely conform the characterization of the genus. In the present studies, the species simlensis has been placed under genus Sphrageidus Maes making a new combination as Sphrageidus simlensis (Gupta) for its proper placement. The genus diagnosis has also been updated. The external morphological characters including wing maculation, venation and particularly the genitalic features proved significant from taxonomic point of view in all the three species.

Full textAbstract:
The visual motion aftereffect (MAE) was initially described after observation of movements in the natural environment, like those seen in rivers and waterfalls: stationary objects appeared to move briefly in the opposite direction. In the second half of the nineteenth century the MAE was displaced into the laboratory for experimental enquiry with the aid of Plateau's spiral. Such was the interest in the phenomenon that a major review of empirical and theoretical research was written in 1911. In the latter half of the present century novel stimuli (like drifting gratings, isoluminance patterns, spatial and luminance ramps, random-dot kinematograms, and first-order and second-order motions), introduced to study space and motion perception generally, have been applied to examine MAEs. Developing theories of cortical visual processing have drawn upon MAEs to provide a link between psychophysics and physiology; this has been most pronounced in the context of monocular and binocular channels in the visual system, the combination of colour and contour information, and in the cortical sites most associated with motion processing. The relatively unchanging characteristic of the study of MAEs has been the mode of measurement: duration continues to be used as an index of its strength, although measures of threshold elevation and nulling with computer-generated motions are becoming more prevalent. The MAE is a part of the armoury of motion phenomena employed to uncover the mysteries of vision. Over the last 150 years it has proved itself immensely adaptable to the shifts of fashion in visual science, and it is likely to continue in this vein.

Full textAbstract:
This study presents a standardized approach to collecting, registering, and reporting field-survey data for baseline MAES (Mapping and Assessment of Ecosystems and their Services) information in Greece. This is accomplished through a web-based platform (MAES_GR) exclusively developed under the relevant, nation-wide LIFE-IP 4 NATURA project. Based on the European Commission’s guidance for ecosystem condition (EC) and ecosystem services (ES) MAES studies, we conceptualized and structured an online platform to support EC and ES assessments, integrating all relevant fields of information needed for registering EC and ES parameters. A novel algorithm calculating EC was also developed and it is available as an integral part of the platform. The use of the MAES_GR platform was evaluated during nationwide field surveys efforts, increasing time efficiency and reducing costs. Field recording of EC and ES pinpoint spatial priorities for ecosystem restoration, conservation and sustainable development. This work highlights that MAES implementation can be favored by the use of technology tools such as mobile survey platforms, developed according to scientific needs and policy guidelines. Such tools, apart from the data inventory phase, can be used for data analysis, synthesis and extraction, providing timely, standardized information suitable for reporting at the local, regional, national and European Union scale.

Full textAbstract:
The oil and gas construction industry continues to experience unnecessary work-related fatalities. The International Association of Oil & Gas Producers (IOGP) reported 80 fatalities in 2013 (IOGP, 2014). When assessing this against the use of OGP Life-Saving Rules (LSRs), which contractors are required to adopt, the IOGP stated that ‘Assessment of the applicability of the OGP Life-Saving Rules to fatal incident descriptions for 2013 data has shown that at least 67% of the fatal incidents reported are covered by the OGP Life-Saving Rules and may have been prevented…’ (IOGP, 2014). While LSRs raise awareness about the hazards and standards required, the rules-based approach has not been effective in preventing fatalities. Clough has rigorously applied LSRs on projects, however, following a fatality in July 2013, Clough re-evaluated the management of major accident events (MAEs) and found that standard safety management practices, including the use of LSRs, were not effective in managing high-risk activities in a dynamic construction environment. As a result, the Major Accident Prevention (MAP) program was developed, bringing offshore safety case principles to the onshore construction environment. These include: to know and understand the activities that give rise to MAEs; to identify and define critical controls; and, to implement a verification regime that confirms the critical controls are effective. This extended abstract describes the advantages of a safety case approach compared to the traditional LSR approach, supported by case studies to demonstrate a real-life implementation of the program on major construction projects.

Full textAbstract:
Background of the study: Most drugs given as Microinfusion require infusion pumps to administer. They are very potent with very narrow therapeutic index and any small changes on the process results in enormous effects to patients. The nursing profession has a duty to advocate for patients rights as well as do no harm. One of the core goals of nurses is medication administration; this puts nurses in the last line of defence against medication administration errors (MAEs). This study aimed to look into the roles played by nurse that hamper the efforts to reduce the Microinfusion MAEs on which minimal studies have been done.
Objective: This study determined the competency level influencing the administration of Microinfusion medication by critical care nurses at Kenyatta National Hospital’s (KNH) Intensive Care Unit (ICU).
Significance of study: Local data in the area of Microinfusion MAEs is not available, specifically KNH’s ICU. This study therefore sought to breech this gap and hopes to influence policy on management of critical patients, patient safety, environment, and curriculum development so as to reduce Microinfusion MAEs.
Methodology: This study used a descriptive cross-sectional study design, simple random sampling was used to pick 64 participants. Quantitative data was analyzed by both descriptive and inferential statistics, which included regression analysis. Descriptive statistics were presented by use of the mean, percentages and standard deviation. Chi-square was used to determine statistical significance of the differences in proportions and logistic regression was used to identify factors that lead to Medication administration errors. Necessary ethical approval was sought.
Results: The prevalence of MAEs was at 64.1% in the last six months, 65.6% 0f the respondents reported lack of supportive supervision, 37.5% of the respondents reported not to know mechanisms in place for reporting Microinfusion medication errors. This prevalence was of statistical significance when cross tabulated with critical care nurses competency level (p<0.05) on aspects such as; having prescription checks [95%CI= 0.000-17.9; p=0.008], working experience, type of medication error, checking weight of patients [p=0.019], reporting of the errors [95%CI = 0.1-0.8; p=0.019], documenting drug errors and monitoring patients after drug administration.
Conclusion and recommendation: The prevalence of Microinfusion administration errors in KNH-ICU is high. There is need to ensure that nurses are always equipped with adequate knowledge and experience in drug administration through trainings and mentorship programs as this will reduce medication errors and increase safety of patient in health facilities.

Full textAbstract:
Within the frames of this study, the synthesis of a permalloy to be used as a filler for magnetoactive and magnetorheological elastomers (MAEs and MREs) was carried out. By means of the mechanochemical method, an alloy with the composition 75 wt.% of Fe and 25 wt.% of Ni was obtained. The powder of the product was utilized in the synthesis of MAEs. Study of the magnetorheological (MR) properties of the elastomer showed that in a ~400 mT magnetic field the shear modulus of the MAE increased by a factor of ~200, exhibiting an absolute value of ~8 MPa. Furthermore, we obtained experimentally a relative high loss factor for the studied composite; this relates to the size and morphology of the synthesized powder. The composite with such properties is a very perspective material for magnetocontrollable damping devices. Under the action of an external magnetic field, chain-like structures are formed inside the elastomeric matrix, which is the main determining factor for obtaining a high MR effect. The effect of chain-like structures formation is most pronounced in the region of small strains, since structures are partially destroyed at large strains. A proposed theoretical model based on chain formation sufficiently well describes the experimentally observed MR effect. The peculiarity of the model is that chains of aggregates of particles, instead of individual particles, are considered.

Blood 136, Supplement 1 (November 5, 2020): 4. http://dx.doi.org/10.1182/blood-2020-139390.
Full textAbstract:
Endothelial microparticles (EMPs) upregulation has been observed in the pathological process of acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). The biological role and therapeutic potential of long non-coding RNAs (lncRNAs) carried by EMPs in aGVHD after allo-HSCT are still open questions. Herein, we investigated the functional significance of the lncRNA nuclear paraspeckle assembly transcript 1 (NEAT1) delivered by EMPs in aGVHD. To address this question, in the present study, we performed a comprehensive analysis of the lncRNA NEAT1 expression and EMPs in aGVHD by a series of in vivo and in vitro experiments. We found that expressions of lncRNA NEAT1 in MPs were remarkably elevated in aGVHD mice than in non-aGVHD mice. Furthermore, the lncRNA NEAT1 levels in the MPs were remarkably higher than those in the plasma of the aGVHD mice. We then used TNF-α (100 ng/ml) to stimulate primary mouse aortic endothelial cells (MAECs) to shed EMPs, and the expression of lncRNA NEAT1 in the EMPs and their maternal cells was compared. The lncRNA NEAT1 levels in the EMPs produced by TNF-α-stimulated MAECs were significantly higher than that in both their maternal cells and non-stimulated EMPs. Our study demonstrates that EMPs could assemble and concentrate lncRNA NEAT1. Taken together, NEAT1 delivered by EMPs could be used as a diagnostic and prognostic surrogate marker for aGVHD, and its targeting could therefore represent a promising strategy for novel therapeutic options in life-threatening aGVHD after allo-HSCT.

Full textAbstract:
We describe Dysponetus joeli sp. nov. from shallow maerl habitats in the north-east Atlantic (English Channel and Bay of Biscay). Dysponetus joeli differs from congeneric species by a unique combination of characters, including a large syllid-like pharynx, 2–4 simple serrated neurochaetae (closely similar to notochaetae, but much smaller and more delicate), D-shaped chaetal spines and ventral cirri on the third segment. A phylogenetic parsimony analysis based on morphological traits suggests that Dysponetus is not monophyletic unless it includes the closely related genera Vigtorniella and Pseudodysponetus, which are well delineated inside the dysponetid clade. Chaetal spines seem to be secondarily derived from paleae and to have originated in infaunal dysponetid forms. They should not be considered as plesiomorphic, but as evidence to support the clade made up by Dysponetus–Vigtorniella and Pseudodysponetus as delineated by a phylogenetic analysis.

Relation of plant diversity with iron ore deposit area in Dhaubadi, Hupsekot rural municipality-5, Nawalparasi district, has been investigated in this study to explore good indicator and accumulator among plants. To identify this, plant diversity, iron accumulation in soil and plants growing on them at different plots were measured. Spermacoceae alata, Anaphalis busua, Isodon coesta and Salvia sclarea were common herbs in all plots and out of them Spermacoceae alata had the highest importance value index (IVI) value among herbs. Among the shrubs Ageratina adenophora, Maesa chisia, Osbekia stellate and Elsholtzia blanda were common in all the plots and of them Ageratina adenophora showed the highest IVI. Plant like Elsholtzia blanda and Anaphilis busua were identified as good indicator of iron deposits because of high amount of iron in their body, especially roots. Among all the sites, Begonia picta at the core area (Site A) had the highest iron accumulation, and most plants found there like Cyanotis vaga, Hypericum japonicum, Begonia picta, Gonostegia hirta, Trumphetta rhomboidea, Osbekia stellata and Isodon coesta had bronze coloration in leaves. The bronze coloration in leaves among plants has been identified as a good indicator to ascertain iron ore deposits.

This essay explores the visual articulation of protection, family care, nurturing, and freedom through the lens of two cloth ancestral figures from early 1920s Edgefield, South Carolina. The doll-like reliquaries, made by healer Ellen Weaver, embody materials from the graves of relatives and engage practices rooted in African American rootworking and conjure traditions. The figures are distinct in that they are small doll forms made to travel with their owners. Created after the accidental death of Ellen’s 2-year-old granddaughter, Rose, the dolls have moved with her sister Lillie Mae from Edgefield to Greens Cut, Georgia, to Queens, New York, and Cleveland, Ohio, where they reside with Lillie Mae’s granddaughter Nancy Stroman. Nearly eighty-five years old, the figures reveal Ellen’s deep commitment in her ability to artistically manipulate supernatural powers and harness the power of the family’s ancestral spirits to protect, heal, and inspire her descendants.
