A theoretical model of a slipper with multi-lands and multi-grooves for swashplate type axial piston pumps and motors was established, including surface interactions. Further, a numerical simulation was conducted under an unsteady state and mixed lubrication conditions. Four model configurations were considered: A slipper with a single main land; a slipper with inner and main lands and a groove; a slipper with outer and main lands and a groove; and a slipper with inner, main, and outer lands with two grooves. Numerical solutions were obtained across a wide range of operating conditions in terms of center clearance, pad attitude, contact pressure, flow rate, friction torque, power loss, and stiffness. The motion and characteristics were differentiated into two groups: Slippers with a single-land and an annex inner-land; and slippers with an annex outer-land and a triple-land. The single-land and annex inner-land slippers exhibited smaller pad swing, whereas the triple-land and annex outer-land slippers reduced contact pressure and power loss.

This paper focuses on the spiritual and gendered experiences of dwelling-in-uncertainty in the context of Bengali char lands. Chars are temporary sandbanks in the river that continuously erode and re-emerge as the river changes course, thereby subjecting their inhabitants to repetitious cycles of losing and regaining land. In this paper I take the ethnographic literature on Bengali chars as a point of departure for exploring what the radical uncertainty of climate change might mean in a context where erosion or land loss does not necessarily involve the irreversible loss of a particular habitat, but often coincides with the anticipation of return. In analyzing the gendered ways in which char dwellers navigate this spiraling cycle of land loss and return, I draw specific attention to the churning, immaterial and spiritual powers that reside below and beyond the water, thereby highlighting the ways in which people are caught up in a land/waterscape that is only knowable to some extent. Whereas debates around climate change often treat religion and spirituality as either obstacles to knowledge or vehicles of meaningful storytelling, this paper deliberately foregrounds the more-than-human forces that linger at the periphery of people’s perception and knowledge of the world. In doing so, the paper seeks to move beyond probabilistic notions of climate change and adaptation towards a diverse understanding of the existential uncertainties of the Anthropocene.

There is a close relation between increment of transportation (roads and vehicles) and socio-economic development of the nation however, present condition of Nepal is discouraging. The study deals with present situation of land transportation, its problems with suggestions. An attempt has been made to point out causes and nature of road accidents, problems faced by general people and businessmen during travel and transportation of cargo. This study reveals that out of 29157 kilometers available road network only 12305 kilometers (42.20 %) road was black topped and the condition of road was miserable because there was no proper and regular repair and maintenance. Graveled roads were in very poor condition and in most of the roads and bridges were not constructed. Earthen roads were not suitable for travelling in rainy season. The buses run on long routes were found violating norm of keeping double drivers, the speed of vehicle remained higher than limit. They unnecessarily used loud or pressurize horn which had created noise pollution. The vehicles moved on graveled and earthen roads had been operating in poor condition. Vehicles were very old and damaged and only a few vehicles moved on certain routes. Vehicle accident incidences had frequently occurred in hilly areas where vehicles plunged down from the road and number of fatalities and injuries were found in double digit. The major reasons of accidents were high speed of vehicles, steering or brake failure, untrained and intoxicated drivers, driving by cleaner/conductor, continuous long duty hours of drivers, poor condition of vehicle, muddy and slippery roads, haphazard overtaking practice on single lane roads, lack of concentration of drivers on driving , non-observance of safety measures, traffic rules and signs, drove vehicle without wearing seat belt/helmet, kept more passengers than allowed/available seats, hung passengers on gate, backside and roof, loaded cargo beyond the limited weight and height respectively.

The paper presents the results of an experimental and theoretical investigation of the effect of clamping ratio and orifice size on the performance of slippers in axial piston pumps and motors. Polishing of the running face to a slightly convex form appears to be essential for successful operation under all conditions. It is shown that slippers operate perfectly satisfactorily with the orifice blanked and, indeed, are generally most stable in this condition. Introduction of the orifice in under-clamped slippers increases the clearance. However it can also destabilise the slipper resulting in the slipper becoming sensitive to the effect of tilting couples. The effect on overclamped designs is more complex depending on the precise value of clamping ratio and on the width of the slipper land.

Navigating the AGV over the curve path is a difficult problem in all types of navigation (landmark, behavior, vision, and GPS). A single path tracking algorithm is required to navigate the AGV in a mixed environment that includes indoor, on-road, and agricultural terrain. In this paper, two types of proposed methods are presented. First, the curvature information from the generated trajectory (path) data is extracted. Second, the improved curve-aware MPC (C-MPC) algorithm navigates AGV in a mixed environment. The results of the real-time experiments demonstrated that the proposed curve finding algorithm successfully extracted curves from all types of terrain (indoor, on-road, and agricultural-land) path data with low type 1 (percentage of the unidentified curve) and type 2 (extra waypoints added to identified curve) errors, and eliminated path noise (hand-drawn line error over map). The AGV was navigated using C-MPC, and the real-time and simulation results reveal that the proposed path tracking technique for the mixed environment (indoor, on-road, agricultural-land, and agricultural-land with slippery error) successfully navigated the AGV and had a lower RMSE lateral and longitudinal error than the existing path tracking algorithm.

In addition to the load from the fluid pressure acting on the piston, slippers in axial piston pumps and motors must carry couples produced by the centrifugal loads from pump rotation and by the friction acting at the piston/slipper ball joint. These couples have a major influence on slipper performance and largely control the slipper clearance and leakage. Small amounts of surface non-flatness are known to be necessary for slipper lubrication and it is shown that, on this basis, the behaviour of slippers when subject to tilting couples can be satisfactorily predicted. Neither the magnitude nor precise shape of the surface profile appears to be of critical importance provided that the slipper lands have a generally rounded and convex profile. Measured clearances under slippers subject to tilting couples confirm the theoretical predictions.

The past sixty years of theatre studies recall the travels of Odysseus. It had a narrow escape from being devoured and digested by the Gallic Cyclops that dwelt in the Cave of Theory. It lingered in the Lotos-land of performance studies, gorging on a bottomless buffet of human activity. It hearkened to siren songs luring it to seductive but slippery shoals of anthropology, ethnography, sociology, and neuroscience. Some of its crew has suffered a Circean transformation into omnivorously rooting cultural critics. Its vocabulary has been inflated by Aeolus, king of winds. Meanwhile, back home there languishes its consort, History, knotting and unknotting a tapestry of documentary material and archival research while urged to bed by suitors from foreign realms.

While enrollment is dropping in many commodity-based curriculums, one key program area of interest to many students is sustainable agriculture. Some land-grant universities are initiating undergraduate and graduate programs, or concentrations in Sustainable Agriculture, to meet this student demand. Many smaller colleges (for example, Delaware Valley College, Slippery Rock Univ., and Warren Wilson College) are also offering a focus in this area as well. These programs often include an experiential learning component through internships and other hands-on activities. Examples of some of the courses being offered include Principles and Practices of Sustainable Agriculture, Agricultural Ecosystems, Sustainable Agriculture Processes in Plant Horticulture and Animal Husbandry, and Fertility Considerations in Regenerative Agriculture. In this presentation, I summarize ongoing programs nationwide, and discuss the impact these programs are having on student enrollment.

Though racism in the form of blatant de facto and de jure policies and domestic terrorism is no longer the law of the land as was the case before, and during the Civil Rights Movement, an intensified dysconscious and color-blind racism has propelled itself in the post–Civil Rights United States, particularly in this “Age of Obama”; one that manifests in semantically slippery and rhetorically convoluted discourses. Consequently to illuminate this specter of American racism, critical race theory and spoken word performative poetics join forces here in an interpretive conarrated description of rhetoric that has recently emerged in the mainstream media—a discourse that attempts (a) to deny Black persons the right to human dignity; (b) to distort and invalidate Black persons’ ideas, thoughts, and feelings; and (c) to deny one’s right to claim and affirm one’s personal identity.

In today’s global celebrity culture it’s hard to imagine a word more over-used and abused than ‘genius’. It is a slippery word with a long and contradictory conceptual history. Yet, in the Land of the Tall Poppy, self-confessions of genius invariably have paved a broad road to public ridicule and denigration. Xavier Herbert’s notion of genius was not static. It changed throughout his life and it evolved through his writing. He agreed with Carlyle that the first condition of genius must always be a ‘transcendent capacity of taking trouble’ and on this foundation he built his own concept of genius, as the unending ‘capacity for loving’. This article explores what genius meant to Xavier Herbert and how it translated into his fiction, before considering how our sense of genius today influences the way we respond to his most challenging fictions of love and hate, 'Capricornia' and 'Poor Fellow My Country'.

ArgumentThis article focuses on the specific ways in which Zionist scientists studying malaria in Mandatory Palestine (1920–1947) presented their work to international scientific circles, moving between the transnational aspects and the local aspects of their work on malaria while suffusing that work with nationalist meanings. This slippery yet seemingly unproblematic movement between the general and the specific, between the colonial world and Palestine, was a necessary mechanism of scientific exchange. In the Zionist case the work on malaria for these scientists was both a marker of their belief in progress and also a sign of their devotion to a specific political and social project. The knowledge imparted by Zionist malariologists and the international reception it received lent scientific legitimacy to the Zionist project while it advanced the goals of settling the land and defining the communal borders within Palestine between the Arab population and the Jewish one. In this way, the Zionist anti-malaria project in Palestine holds a unique place in malaria research of the time.

ABSTRACTCode riverbanks are dominated by land for settlements, one of the points being the proposed establishment of rusunami, in Jetisharjo, city of Yogyakarta. Riverbanks at the location are slippery, so have many problems of structure and infrastructure. In the planning of rusunami, it is necessary to consider the location of the communal septic tank.

Abstract The leakage across the slipper land of a swashplate type axial piston pump is inherent in almost all the commercially available designs. This occurs due to the back flow of each piston through its orifice and gap between the slipper and swashplate. This flow phenomenon is studied in detail in the present work. To optimize pump performance with a reduced leakage, it is critical to know the fluid dynamics within the pump passages. In this paper, a three-dimensional CFD methodology has been created and employed to predict the pump performance in terms of pressure field, velocity vectors, and the flow pattern to understand pump flow. The methodology is established in the commercially available code ANSYS FLUENT 16.0 which supports the existence of complicated geometry in the form of narrow orifices and gaps between rotating and stationary walls. Slipper leakages, velocity and pressure fields are computed using simple algorithm approach at different designs and operating conditions. Experimental data of the film thickness is used in the present simulation. The effect of different piston pressure, slipper velocity, oil viscosity, slipper orifice diameter and slipper pool inner diameter is studied. Investigations of this kind may help for the development and design of slippers.

"The Evolution of the Area between Valea Chintăului and Valea Caldă Following the Works Mitigating Soil Erosion. The study area is located on the left slope of the Someșul Mic River, in the northern part of Cluj-Napoca and is bounded on the north and east by the watershed that separates it from the Valea Caldă River basin, south of the agricultural road that separates the slope from Someșul Mic floodplain and west of the orchard border. The area is called Sfântu Gheorghe Hill, the homonymous peak bordering it to the west, and Țigla Hill to the east. In 1986, the Institute for Studies and Design for Land Improvements implemented a plan to mitigate soil erosion on an area of 600 hectares within the mentioned limits. Of these, 300 hectares represented the arrangement of terraces, 200 hectares the arrangement of landslides and 100 hectares of drainage on slopes. The execution of the works mitigating soil erosion aimed at reducing the annual soil losses, the possibility of applying appropriate agrotechniques in the fruit plantations to be established. The arrangement of the slippery surfaces was done by modeling, eliminating the excess moisture, terracing, grassing or planting and had the purpose of bringing significant areas of land back in the economic circuit. Elimination of excessive water through drains was made for the proper development of future tree plantations. The purpose of this study is to analyze the temporal evolution, over a period of 30 years, of the efficiency of the arrangement works on the slope performed in 1986, first of all. The estimation of the effectiveness of the works executed at that moment was made by the comparative morphometric and morphological analysis of the landslides and the forms of deep erosion on the slopes. Second, the study examines the vulnerability of landslide risk factors in this area, in particular residential and public buildings, road infrastructure and agricultural land. The study starts from the following premises: the geomorphology of the southern slope of Sfântu Gheorghe Hill has been studied over time, as attested by bibliographical sources; 30 years ago, the destination of the lands related to the area was mainly agricultural, and the land use plans included mainly measures for agricultural development; in recent years, there has been an accelerated expansion of Cluj-Napoca, including on the northern slope of Someșul Mic, both from the base of the slope to the watershed, and along the base of the slope, to the eastern outskirts of the city. The questions that arise are: how did the landslides evolve and how did the slope evolve after the development carried out in 1986? How many of the built elements are located in areas with acceptable risk and how many are located in areas with high risk in terms of slope stability? Keywords: landscaping, soil erosion, landslides, torrents, terraces, modeling, vulnerability. "

Oil palm plantations on peatlands have a high acidity level and have an unstable soil structure. In the rainy season, the land surface tends to be slippery and stick to vehicle footwear or tires. While in the dry season, the soil is dry, flammable, and dusty, especially if it is passed by a four-wheeled vehicle with a significant weight and size. Farmers transport the harvest of palm fruit using a small size conveyance, a type of �arco� capacity 50-70 kg, plastic drum capacity 40-50 kg, and peninsula capacity 30-40 kg. The process of transporting palm fruit from harvest to the mill takes a long time, potentially harming farmers due to �restan fruit� (palm oil is loose from the stem). The leading cause is the conveyance that is used in small volumes and is done by human labor. Palm fruit to stay fresh arrived at the processing plant with a duration of no more than 2 x 24 hours, if late farmers experience a loss of 10-15% because the weight of the scales is shrinking. The innovation of traditional conveyance capacity 500-750 kg based on used materials has been carried out using a special design that takes into account the carrying capacity, labor, road conditions, and timeliness so that the fruit does not become �restan.� Farmers are much helped both in terms of energy, process (time), transport volume, and can be operated on peatlands in both the rainy or dry season.

In conversation with Eva Hayward’s writing on transgender embodiment, this paper explores how beaver modify landscapes differently than human engineers, and how human engineering might be transformed through riverine collaborations with beavers. Considering the body variously as a body of water — a river, which draws together all of the above and underground water in a watershed — as like our own trans bodies, and as a slippery double for the psyche of an Anthropocene engineer, July Cole and I argued that thinking with beaver as stochastic transgressors against Manifest Destiny engineering projects could transfigure engineers approaches to their work and river restoration more broadly. What if, rather than trapping beavers into service as “ecosystem engineers,” we assert that humans should engineer as beavers do, in ways that create porous boundaries between land and water and up- and downstream, by way of stick-and-mud, leaky, temporary dams? Here, I theorize a transfigured watershed body through human-beaver-salmon encounters at three salmon recovery sites in the Pacific west: a Karuk-led project on the Klamath river, agency-led beaver relocation projects in the Methow and Yakima watershed, and a citizen science-agency collaborative project in the beaverless Salmon Creek and Russian River watersheds. All three stories concern river and salmon recovery in the Pacific West, where either humans or beavers have initiated collaborative projects to raise water tables, keep rivers from going dry, and improve salmon habitat. These scientists and local knowledge holders’ encounters with beavers and their ponds thick with salmon are inspiring them to change how they undertake habitat restoration projects and also spurring some to reconsider the proper task of human ecologists and engineers, into a mode inspired by beavers themselves.

ABSTRACT In 2011, the Swedish coastline suffered two major oil spills. About 500 tonnes of bunker oil occurred in the marine waters of the west coast, in the waters of Skagerrak, on to the coastline of the Tjörn archipelago. The second spill, about 800 tonnes of CTO (crude tall oil) occurred from a land based tank farm on the east coast, into the Söderhamn archipelago in the brackish Baltic Sea. Both impacted areas exhibit a high ecological value and are frequently used for outdoor recreation. In Söderhamn, many private properties were impacted as opposed to Tjörn, where the archipelago is common land. The affected coastal area at Tjörn comprise rocky beaches with varying degrees of cracks, bays, rock pools, etc. At Tjörn, remediation has been made through manual labor combined with experimental methods facilitating faster manual removal; such as mineral oil degreasers, coconut oil, rapeseed oil, and heating up the oil by means of a torch. Manual labor through scraping with various tools (e.g. spatulas, knives, cloths) has however been the main method. The remediation was difficult and dangerous due to the slippery rocks and tough weather conditions. The shores of the Söderhamn Bay consist mainly of rocky beaches, large rocks as well as very small pebble stones. Since the oil also got into jetties, the entire clean-up process has been difficult and time consuming, also due to the cold weather conditions in the north. Remediation of the shores and stone coffins, inside the jetties, has been made through manual labor. The impacts to the bird population were minimal in both incidents since most birds had migrated for the winter. At Tjörn, some short-term impact could be noted on indicator species like the Blue mussel. The incident happened during late fall, when the biological activity in marine organisms is low; hence low impact on the marine organism's active reproductive periods. In Söderhamn, fatty acids, recin acids and sterols have been sampled in sediments, fish muscle, and mussels. Limited impact could be noted, however, established test methods are missing for CTO. Degradation time of the CTO was longer than expected. Extensive and hardcore cleanup usually causes more damage to nature; removal of important microorganisms, increased soil erosion and diminishes the possibilities for the vegetation recovery. It is cucial to start the communication process with public and property owners as early as possible to set expectations on how clean is clean.

The dam Mavrovo on the Mavrovo Lake was built on the river Mavrovska at the very exit of the Mavrovo field. The dam can relay in several cases: war, natural disasters (tectonic disturbance, earthquake, flood and human factor), and antiterrorist attack. During the demolition of the dam, a flood wave would be formed along the valley of the Mavrovska River and the Radika River. The basic, main and priority goals that are expected to be achieved after the conducted research, analysis and preparation of this paper are as follows: Realization of the possibilities for reaction and support for cracks, collapse and other damage to dams, Realizing the possibilities for reaction and support if cracks, crashes and other damage to the dams, creating conditions for the occurrence of infectious diseases in humans, animals and plants, achieving the possibilities for reaction and support if cracks, crashes and other damage to dams, resulting in greater material damage to the habitats, destruction of industrial capacities of livestock farms, etc., Realizing the possibilities for reaction and support in the event of an earthquake, Realizing the possibilities for reaction and flood support, Realizing the possibilities for reaction and support during intensive snowfall, snow drifts, avalanches, landslides and more land-slippery landscapes, Realizing the possibilities for reaction and support at extremely high or low temperatures and dense fogs and I have achieved ment opportunities for response and support large-scale fires. In the event that there is a drainage of the dam, if there are no previous optional solutions for managing the possible consequences, there will be a natural disaster on a considerable scale.If the dam is destroyed, it is expected to be destroyed: The entire road infrastructure from Mavrovo to Debar; The economic capacities of the same move, Family homes after the flow of the river radika. There are climatic and pedological consequences and Disruption of biodiversity in the region.

The tribal aristocracy in The Golden Horde Khanate and its successors, shaped by the steppe culture, developed with the elements inherited from the ancient heritage of geography. Since the Asian Hun State, the legacy of four numbers, which has come to the forefront in political, military and social life, has found its place in the name of the Four Beys System / Four Karaçu Beys. The four beys system has become one of the essential elements of the administration in addition to the Khanate position in the Crimean Khanate. The beginning of this system is based on the 4000 soldiers given to Cuçi in the land and tribal division made by Genghis Khan to his sons and the Kıyat, Seycut, Kinhit and Hüşin tribes to which they belong. Although the Mongolian tribes, which were a few in number in the ancient Turkish homeland of Cumania, they tried to keep the rule under the leadership of the Kıyat, and lost their authority after the silence of the Ak Orda (White Horde) dynasty. With the leadership that changed hands between the Mangit and the Sirins, the intertribal balance of power was transferred to the Sirin, Barın, Argin, Kipchak and Mangit tribes under the leadership of the Sirins, who played an active role in the establishment of the Crimean Khanate. The Tribes played an active role in both, internal and external affairs of the Crimean Khanate under the chief Karaçu of the Sirin tribe. After the Crimean Khanate came under the Ottoman protection, the Karachu beys, on the one hand, became the assurance of the Genghisids to hold the throne, on the other hand, they became the control element of power of the Genghisids. The Karachu beys’ keeping the interests of their tribes above everything, has turned the relations in the north of the Black Sea into a slippery ground where the balances were constantly changing.

The profile of sealing land is a sensitive factor affecting the thermo-hydrodynamic lubrication characteristics of the slipper pair. In this paper, the non-uniform wear of the running surface under the slipper was presented and defined as the boundary condition. Based on the finite volume method and the successive over-relaxation iteration method, a discrete numerical model coupled with the temperature, pressure, and thickness of the oil film was constructed. The Newton and sequential circulation methods were used to solve the coupling equations. The influence of the wear profile on the film thickness, sliding attitude, and leakage were discussed. The analyzed results show that the control of the wear on the outer side of sealing land and the contour vertex position, and the avoidance of the wear on the inner side of sealing land could improve the thermo-hydrodynamic lubrication performance of the slipper pair.

This study aims at the lubricant film between the slipper and swashplate of an axial piston pump. Based on a single piston/slipper assembly model, a mathematical model for the squeeze film effect is developed according to the pressure-flow transfer process as well as the dynamics of the piston/slipper assembly. The squeeze film effect on the slipper lubricant film has been predicted by nonlinear numerical calculations and computational fluid dynamic (CFD). The slipper lubricant film thickness and leakage flow, sealing land pressure distribution, and load carrying capacity are evaluated as important parameters to indicate the performance of slipper oil film. The influence of piston/slipper assembly geometric parameters, oil compressibility, and oil viscosity on the squeeze film effect under pressure pulse has been studied, and the effect of squeeze film speed on the support force of slipper lubricant film has been given out.

The essay examines how Melville's “The Encantadas” reveals the colonial underpinnings of seemingly disinterested nineteenth-century natural history, particularly Darwin's The Voyage of the “Beagle.” Whereas Darwin's formulation of the Galapagos Islands grants readers dominion over exotic lands, Melville's slippery islands defy the classification-as-preparation-for-occupation scheme of texts like Darwin's.

Abstract Porous asphalt is a pavement layer structure with aggregate gradations with a coarse fraction greater than 70-85% of the total weight of the mixture so that the resulting structure is more open and porous, which prevents water from stagnating on the road surface reduces water splash and makes the road less slippery.

Rhazes (855-925 AD) the great scholar of Unani System Medicine (USM), initially classified Materia Medica according to animal, mineral and plant origin. Zahar Mohra is a Greenish white, good‑looking mineral stone with a slippery feel having a good smell and taste obtained from mines. In USM it is considered to be a universal antidote. The great Unani Scholar Yuhannā Māsawayh (777-857 AD), was one of the first physicians who mentioned the medicinal uses of Zahar Mohra. In Unani Medicine it is used to treat epidemic diseases such as Haiza (Cholera), Tawoon (Plague), as an antidote for different poisoning and to provide strength to vital organs. To check adulteration the quality standard of Zahar Mohra has been laid down. All the available information regarding this historically important stone has been compiled which will help the researcher to find a solution of pandemic disease in the current scenario. Key words: Zahar Mohra, Unani Medicine, Fade Zahar Kani, Mineral Bezoar

Publicity accorded American physician-pathologist Jack Kevorkian and “physician-assisted suicide” bring a new, technological, twist to euthanasia. How and when we die and its meaning and how we live reflect cultural values within a historical context. High costs of medical care for the terminally ill when the cost of health care is the most rapidly rising portion of the consumer price index, Medicare expenses are the highest in the last year of life, and an estimated thirty-seven million people remain uninsured make euthanasia increasingly salient. Faced with great pain and the emotional and financial burden that often accompanies prolongation of life during terminal illness, the decision to die is not necessarily irrational, psychotic, or delusional but pragmatic. Yet inherent risks have often been overlooked in discussions of “the right to die.” This article reviews cultural values associated with beliefs about assisted suicide, the experience of other nations including the Nether; lands with assisted suicide, and the “slippery slopes” inherent in legitimization of physician-assisted suicide.

This paper presents the field investigation of a major landslide that occurred in a newly dredged slope for port development in the city of Tianjin, northern China. The dredged slope comprised underconsolidated soft clay of recent marine and river delta deposits. The landslide consisted of a number of individual slides that occurred sequentially and extended retrogressively and laterally into reclaimed land. It lasted for about 1 h, occupying a plan area that is about 200 m long and 150 m wide in the reclaimed land. The failed soil mass was estimated to have a volume of between 700 000 and 800 000 m3. Part of the failed soil mass slipped into a newly dredged open space in the sea. The distance of the debris travel into the berth was about 80 m. The debris surface had a gentle slope of about 3.0°. The angle from the dredged slope crest to the far edge of the debris was about 6.8°. A common rupture surface was found underneath the debris and above the in situ marine mud. It controlled the inland extension of the slope failure. The landslide occupied an inclined area of between 27 000 and 30 000 m2, with an overall slope angle of about 3–4°. A kinematic model is proposed to explain the extension of the landslide into the reclaimed land. Findings of this field investigation are further used in the companion paper for a theoretical investigation of the mechanism of the landslide. The engineering approach and results presented in this study could be useful in the design and construction of dredged slopes in underconsolidated soft soils. Key words: port development, land reclamation, dredge excavation, landslide investigation, soft soils, case studies.

Abstract The Farm Crisis of the 1980s was not just an economic crisis, but an identity crisis for the two-thirds of Iowa farm families that risked losing their livelihoods. Confronted with a situation that was well outside of their control, they sent thousands of letters to government officials, asking for, and sometimes demanding, answers. Many of those letters expressed puzzlement, anger, and disappointment as writers tried to explain how the hopes and dreams of a lifetime had slipped through their grasp. They expressed deep frustration with politicians, consumers, and even other farmers who did not understand or sympathize with the stresses imposed by markets, environmental forces, and government policy that first encouraged borrowing and expansion, and then punished those who had followed that advice. Although the Reagan administration eventually responded, it was not before a significant number of farmers had left, or been removed from, their land.

Our hypothesis was that technique of formation of each layer of a surgical knot was important to its security.DesignEqual numbers of knots were tied, by each of three groups, using three techniques, for each of four suture materials; a standard flat reef knot (FRK), knots tied under tension (TK) and knots laid without appropriate hand crossing (NHCK). Each knot technique was performed reproducibly, and tested by distraction with increasing force, till each material broke or the knot separated completely.SettingTemporary knot tying laboratory.MaterialsThe suture materials were, 2/0 polyglactin 910 (Vicryl), 3/0 polydioxanone, 4/0 poliglecaprone 25 (Monocryl) and 1 nylon (Ethilon).ParticipantsThree groups comprised, a senior surgeon, a resident surgeon and three medical students.Outcome measuresProportion of each knot type that slipped, degree of slippage and length of suture held in loop secured by each knot type.Results20% of FRK tied with all suture materials slipped; all knots tied with the other two techniques, with all materials, slipped, TK (100%) and NHCK (100%). The quantitative degree of slip was significantly less for FRK (mean 6.3%–, 95% CI 2.2% to 10.4%) than for TK (mean 312%, 95% CI 280.0% to 344.0%) and NHCK (mean 113.0%, –95% CI 94.3% to 131.0%).The mean length of suture in loops held within (FRK mean 25.1 mm 95% CI 24.2 to 26.0 mm) was significantly greater than mean lengths held by the other techniques (TK mean 17.0 mm, 95% CI 16.3 to 17.7 mm), (NHCK mean 16.3 mm, 95% CI 15.9 to 16.7 mm). The latter two types of knot may have tightened more than anticipated, in comparison to FRK, with potential undue tissue tension.ConclusionMeticulous technique of knot tying is essential for secure knots, appropriate tissue tension and the security of anastomoses and haemostasis effected.

Wakatobi's prestige has recently dimmed compared to other similar tourism areas in Indonesia. Carrying the theme of a real underwater paradise in the center of the world's coral triangle, it is sometimes slipped by local people as hell on land. The cause of this phenomenon is the lack of understanding on the power of objects, especially objects in terrestrial areas, whereas tourists who come to Wakatobi spend time not only under the sea, but also more time on land. The aims of this study were to provide information about tourist attractions in Wakatobi in terms of originality, authenticity, uniqueness, diversity, and beauty. Data and information were collected by means of document searches and interviews with key informants. The result showed that Wakatobi cannot be viewed as just one place but the four major islands that compose it. In general, natural, historical, and cultural tourism are spread throughout the islands in Wakatobi. Icons that can be highlighted as strengths of each of the four main islands include dolphin migration attraction in Wangi-Wangi, historical and cultural heritage attractions, especially the Lariangi Dance in Kaledupa, underwater beauty in Tomia, and geological landscape of the rock garden in Binongko. All tourist attractions in Wakatobi shall be connected with the strengthening of infrastructure, which currently seems to be concentrated in the capital only.

Abstract. Several examples in western Europe have shown that, at least for deep-seated rotational slides, reactivation of formerly slipped masses is a more frequent phenomenon than the occurrence of new landslides, therefore representing a higher hazard. We selected a study area comprised of 13 landslides located in the Flemish Ardennes (West Belgium) and predicted the hazard related to scarp retreat. The scarp reactivations were identified from the comparison of DTMs produced for 1952 and 1996. Robust results were obtained with the Gamma operator of a fuzzy set approach and a combination of geomorphic, topographic and land use data. We built first a prediction model from the relations linking the 1952–1996 retreat events to the conditioning parameters of 1952. The prediction rate of the resulting susceptibility map is estimated by a cross-validation procedure. We then applied the statistics of this model to the data of 1996 in order to produce a susceptibility map responding to the present-day conditions. Finally, we estimated the conditional probabilities of occurrence of future reactivations for the period 1996–2036.

Recent surveys led by the author in Karaburun Peninsula discovered multiple prehistoric sites. This article introduces one of the Neolithic sites called Kömür Burnu in this marginal zone of coastal western Anatolia. The site offered various advantages to early farmer-herders including freshwater and basalt sources as well as proximity to agricultural lands, forested areas and marine resources. The plain slipped pottery from the site suggests a date between 6200-6000 cal. BC for the Neolithic occupation. P-XRF characterization of obsidian pieces from Kömür Burnu revealed that these were acquired from two different sources (Melos-Adamas and Göllüdağ). These constitute the first evidence for the participation of Karaburun early farmer-herders in the exchange networks that were active in Neolithic Anatolia and the Aegean. The differential technological features of these pieces concur well with the dual obsidian mobility model suggested by M. Milić for the western Anatolian Neolithic.

Mango (Mangifera indica L.) is an economically important fruit crop in the tropical and subtropical areas of the world. In southern Taiwan, mango is grown on 18,000 ha of hilly land mainly located in Tainan, Kaohsiung, and Pingtung. Tons (180,000) of mango with a value of NT$6.6 billion (US$206 million) are produced annually. In 2008, mango fruit rot disease was observed 1 week after harvest on 30 to 72% of stored mangoes collected from seven orchards in southern Taiwan. The initial symptom was a small, brown lesion and rot symptoms advanced progressively. Two predominant fungi were isolated from the margin of lesions on acidified potato dextrose agar (PDA with lactic acid, pH 3.8). Isolates of each fungal type were transferred to 2% water agar containing sterilized pine needles and exposed to near UV light to induce sporulation. For the first fungus, conidia obtained from pycnidia were ovate, one-celled, and hyaline, with an average length and width of 12.93 ± 0.93 × 6.98 ± 0.40 μm and an average length/width ratio of 1.85. To confirm the identity of the fungus, PCR amplification by universal primers, ITS1/ITS4, and DNA sequencing of the internal transcribed spacer (ITS1-5.8S-ITS2 rRNA gene cluster) were conducted. The internal transcribed spacer (ITS) sequence of ribosomal DNA of this fungus was analyzed and submitted to GenBank (Accession No. GQ421486). It showed a sequence identity of 100% with Neofusicoccum mangiferae (Syd. & P. Syd.) Crous, Slippers & A. J. L. Phillips) (GenBank Accession No. AY615185). For the second fungus, conidia obtained from pycnidia were fusiform, one-celled, and hyaline, with an average length and width of 22.87 ± 1.32 × 6.42 ± 0.46 μm and a length/width ratio of 3.53. The ITS sequence of ribosomal DNA of this fungus was analyzed and submitted to GenBank (Accession No. GQ421485). It showed a sequence identity of 100% with Botryosphaeria dothidea (Moug.: Fr.) Ces & De Not.) (GenBank Accession No. AY 786321). To test pathogenicity, four mango fruits were wounded with a sterile needle, inoculated with mycelium agar plugs (0.5 mm in diameter) excised from separate monoconidial cultures, and incubated in a plastic box with a 100% relative humidity for 2 days at room temperature. Brown lesions appeared on all wounded sites of each fungus 2 days postinoculation. In control experiments, sterile agar plugs were placed on the wounded mango fruits. These fruits remained completely free from symptoms throughout the experiment. The pathogen was reisolated from the lesions of inoculated fruits and identified as N. mangiferae and B. dothidea, thus fulfilling Koch's postulates. N. mangiferae and B. dothidea have been reported on mango trees in Australia and South Africa (1). To our knowledge, this is the first report of these fungi causing fruit rot of mango in Taiwan.

RW03 Kampung Belakang, Kamal Village is a RW that BPS (Bureau of Statistics) in 2016 is declared a slum area of ​​DKI Jakarta. While Rt 09 and Rt 10 is RT which became the focus of slums in RW03. People here work as farm laborers, laundry workers and slipper factory workers in freelance.Lack of public awareness at RT.009 and RT.010 / RW.03 Kamal Village, Kalideres Sub-district West Jakarta to live in clean and healthy environment becomes the main problem of the community. Waste contained in vacant land, drainage and roadside due to unavailability of public and private waste disposal facilities. Often leads to flooding and the incidence of unpleasant odors. Rubbish is actually a potential partner of Community. To raise the potential of garbage in Kampung Belakang, RT.009 and RT.010 / RW.03 Kamal Village, Kalideres Sub-district, West Jakarta, become a source of income and livelihood of the people there. So do change the mindset and the way people view the waste. Environmentally friendly education and waste are urgently needed.The output are 1. Recycling Clinic, 2. Fertilizer Formation and 3. Formation of Garbage Bank, through the method of handling education of handicrafts from plastic waste, making fertilizer and storing garbage in Garbage Bank. The accompaniment is carried out together with the NGOs Nyiur Budi Luhur and the Kamal Community Self-Reliance Society.Counseling activities involving volunteers from the community are appropriate, as volunteers are also part of the community. Finally, Kampung Petani Sampah in RW03 was successfully inaugurated by Kali Deres Sub-district, as well as holding a community recycling bazaar.

Commuting helps to keep balance between residence and workplace of workers. With growing accessibility and connectivity, the importance of commuting is increasing all over the world. It is becoming a major substitute to migration. In commute-studies, commute-pattern is an important chapter. It highlights commuters’ directions of movement, distance they cover, modes of transport they use, the time they take to commute, etc. Unlike the urban-based commute pattern, commute pattern in rural areas are relatively an under-researched issue. In fact, traditionally rural people are thought to carry a sedentary lifestyle. Using primary data, this study aims to explore the commute patterns of rural workers located in the village of Gandharbapur of Barddhaman district of West Bengal, India. All the commuters were found to be engaged in non-farm work. Commuters stem from two major groups. One group of commuters is accumulated farm-income induced. They possess sufficient agricultural land. Investing their surplus farm-income, they have established non-farm works. The second group of commuters is poverty-driven. They are landless poor or are marginal farmers and to escape poverty, they have slipped into these works. Located beyond the suburban area (Memari being the nearest town), most commuters commute to nearby rural areas. Due to non-availability of public transport, women commute less than men do. Regular-paid government employees commute longer than other workers commute. The article concludes with a summary of findings and recommendations for further research.

Purpose Aiming at improving the mechanical efficiency, the applicability and the working life of high water-based hydraulic motor (HWBHM) under working conditions at low speed and high pressure, the friction performance of different matching materials for piston slipper – crankshaft pair with high water-based hydraulic fluid (HWBHF) under working conditions at low speed and high pressure – were studied. Design/methodology/approach The friction experiments for different materials (316L, 316L with surface coating OVINO – tetrahedral amorphous carbon [TAC; 316L-TAC] – 316L with surface coating OVINO-graphite intercalated compound [GIC; 316L-GIC] and polyetheretherketone [PEEK] reinforced with 30 per cent carbon fiber [PEEK-30CF]) under HWBHF lubrication were implemented on a pin-disk friction abrasion machine to determine the variations of coefficient of friction (CoF) and wear rate for each matching materials. In addition, the roughness and the morphology of worn surface of different matching materials were quantitatively characterized. Findings The study revealed that material combinations have different friction performances. Test results showed that the abrasion of matching type stainless steel (SS) and SS is rather serious, and the method of surface coating could improve the friction performance of SS when friction with other materials. For matching type of SS with surface treatment (SS-ST) and SS-ST, 316L-GIC and 316L-GIC have relatively stable CoF, and the wear rate was smaller than other matching materials, while 316L-TAC and 316L-TAC has the smaller CoF than that of 316L-GIC. Matching materials 316L-GIC with PEEK-30CF of matching type SS-ST and PEEK-30CF has more stable COF and better wear resistance than those of other matching materials. Originality/value This research has laid a foundation for the improvement of service life and working efficiency of friction pair in HWBHM under working conditions at low speed and high pressure.

The spread of the COVID-19 virus has been halted partially due to the vaccination program around the globe. However, such initiation has been actively under attack by a portion of society that believes vaccination is not the way out of the pandemic. A similar notion of anti-vaccine has slipped through Malaysia, particularly in the education sector, as they refuse to be vaccinated. This has been contributed by the lack of legal provision that regulates vaccination in Malaysia. Based on the literature and scientific data on the effectiveness of vaccination programs in curbing the spread of COVID-19, this paper aimed to weigh the legal argument on the possibility of imposing mandatory COVID-19 vaccination in Malaysia’s education sector to eradicate this deadly disease virus permanently. This paper embarked on a comparative, doctrinal analysis methodology where secondary data were collected and analysed. Literature from primary and secondary sources such as the laws, guidelines, textbooks, journal articles, government reports, newspaper articles, and online sources from multiple jurisdictions was analysed. The outcome of such analysis is laid down in a narrative design in highlighting the importance of mandatory vaccination within the education sector. This paper proposed hard and soft approaches on imposing mandatory vaccination programs within the education sectors in Malaysia is highly recommended, considering that the benefits of vaccination outweigh the risk of eradicating COVID-19 in Malaysia.

This year was the first of our five year project. We established three primary study areas to examine possible biological effects of large predators on moose. Sites where fieldwork was conducted included apparent heavy predation by grizzly bears [the eastern slopes of the Talkeetna Mountains (Alaska)], little or no predation (Grand Teton National Park), and human predation (Bridger-Teton National Forest), the latter two in the southern portion of the Greater Yellowstone Ecosystem. Data were gathered in Alaska from April until August and, in Wyoming, for all months from February until August (except during April). At the southern Greater Yellowstone sites, information was collected on pregnancy rates, calf production, twinning, and juvenile and adult survivorship. Ecological and behavioral data gathered from all three sites included home range locations, foraging associations and rates, habitat use, group size, social interactions, migration, and responses to humans and potential predators. Twenty animals were radio-collared at the Wyoming site; as of December 1995 only 15 survived. One apparently starved to death, one was poached, one was legally shot, and two died of unknown causes. We improved our sample by using 13 females previously radio-collared on national forest lands by University of Wyoming and Wyoming Department of Game and Fish personnel. Of these, two died during the 1994-1995 winter and three had slipped their collars.

The legal process of gaining an enclosure could be long, complicated and expensive …. It could take up to six years, during which time a farmer did not know what was happening or how to farm. (S. Wade Martins,Farms and Fields(1995), p. 81).The impact of parliamentary enclosure in England has been a subject for debate since at least the 1870s. A series of issues has been identified and discussed including the costs of enclosure; the effect of enclosure on small farmers, small owners, and cottagers; the role of the commissioners; the implications for farm sizes; the impact on agricultural productivity and rents; and the significance for the landscape. Yet the quotation with which we open this paper suggests that there is a subject which has slipped through the historical net, the impact of enclosure on farming. In their work published early in the twentieth century the Hammonds noted of the enclosure of Stanwell in Middlesex (Act 1789) that the nominated commissioners were empowered to direct the course of husbandry ‘as well with respect to the stocking as to the Plowing, Tilling, Cropping, Sowing, and Laying down the same’. W.H.R. Curtler, in 1920, quoted the main substance of the clauses from the Cold Aston (Gloucestershire) enclosure act of 1795: ‘from the passing of the Act until the Award the Commissioners were to direct the course of husbandry in the open fields’. He noted also that earlier acts had stated that the existing course of husbandry should be retained until the award was completed. W.E. Tate wrote as recently as 1967 that during enclosure ‘the general course of agriculture in all the open fields was being carried out under directions laid down by the commissioners’.

Planet Earth is a little one, and on one side it hosts the continents and on the opposite side is the Pacific Ocean, where the dry land represents 29%, from which 30% are deserts and 20% are mountains, while 50% is used for human activities. An integrated environment includes Earth and humans [1], as part of the Earth’s fauna, and any living creature from few nanometers up the very large ones, having in common pursue of life. The recent planetary SARS-Cov-2 pandemic [2] placed a special stress on the planet, and placed in the lime-light the dominant characteristics and moral values of humans, their incapability to identify a real threat, adapt and prevail. Due to coarse incompatibility of moral values of various nations, with real life values, many nations ended up politicizing the pandemic and having inappropriate preparedness and response, and as a consequence they recorded high losses in human lives and standard of lives. Earth registers a record high of death, of about 7 Million from which USA worth only 4% of Earth’s population contributed with an exceptionally tragic milestone of 1 Million deaths [3]. Due to inappropriate measures to stop the pandemic, the planet slipped into economic troubles as inflation and supply cycles disruption, that set a supplementary pressure to climate challenge, and for some with terrible moral values for which truth is their enemy, needed an escape goat to distract from the real economic and cultural problem and badly needed a new war, in an exacerbation of xenophobia, hypocrisy and misinformation [4]. This new calamity, has good chances of transforming into a nuclear war, where about 10,000 strikes of about 100 Mt-TNT might be applied to northern hemisphere [5]. In the present conditions COVID is embedded in the environment [6], with new variants due to pandemic as delta, O’micron and BA2, and few more, and from environment is given back to humans, and a new surge appeared in Europe with a delay of about 2 mo. from the elimination of all restrictions. This means that by April- May US will be infected again, with a new version escaping previously made vaccines. In the eventuality of a Nuclear War, ignoring the directly affected areas, the presence of heat and then cold, radioactive pollution, will trigger the gain of function of many passive, or dormant viruses, which will find a new ground of reproduction on the hoards affected by the exposure to nuclear warfare, and having handicapped immunity systems [7]. The survivors from the nuclear war will find difficult to survive to the pandemic with radiation enhanced novel viruses and functional structures.

Hameed goes to the city to sell his crops and buy some goods for his wedding. His fate leads him to meet a thief. He beats the thief and is taken to prison. At the beginning of the story, Khalil I. Al-Fuzai paints a living picture, showing how farmers arrange their trips to the city, using donkeys as a means of transportation. The animals are treated without mercy; though living creatures, they are beaten and overloaded: “The donkey may feel the human being’s injustice. Hence it takes the opportunity to drop its load and run away … 3” and “donkeys … shake their heads up and down with each step they take …” as if commenting on their owners’ treatment of them. The story addresses the village-city relationship as well; the city is important for village residents as a marketplace where they can “sell their loads of fruits and crops from their farms …” and buy what they need for their families and neighbors, as shown in both this story and the previous one, “Thursday Fair.” In other stories, like “Wednesday Train,” people go to the city to look for jobs. In dealing with city customers, experience and advice are important; if the protagonist had not figured out that the customer had disappeared into a mosque and slipped out the other door, he could have waited as long as he wanted and still have left empty-handed. In this case, the advice of Olyan’s mother in “Thursday Fair” is relevant for naïve village youths: “Salesmen of the city are deceitful, so be careful, O Olyan.” The same is true for city customers, as this story shows. On the other hand, the story demonstrates that one of the main characteristics of rural people is that they are helpful and united, so the author refers to them as if they are one cooperative group. The country people are also hard workers. Even on his wedding day, Hameed goes to the city to sell the crops of his land. As a countryman, he does not want to bother his friends, and likes to assume his business on his own: “It will be a burden for you to add my things to yours to sell.” In addition, the story refers to a cultural issue: In some Arabian societies, a man cannot see the woman he is going to marry until she becomes his wife—and at that moment, he cannot go back on his word. Usually, a man’s female relatives choose the girl and, if her family accepts the proposal, then the man’s family prepares for the marriage. Hence, it is the judgment of the female relatives that rules in such situations. Sometimes a previous friendship or an earlier acquaintance between the two females may affect the whole story, as we will see in “Wednesday Train.” So, “the bride here to some extent is similar to a watermelon …” for the bridegroom. Hameed uses “watermelon” in his simile because he knows well such a fruit; it is his main produce. At the end, the story refers to an administrative issue: a cop “takes [Hameed] to the police station.” In the afternoon, all the investigators at the police station are either busy with cases they want to finish before going home, or they have already left their offices, so Hameed must spend the night there, waiting for the next business day before an investigation can take place. Briefly, this story relates that village people are simple and innocent, but when it comes to values they believe in, they do not hesitate to take action.4

The Son of the Widow from Nain.By Kaj ThaningThis article intends to elucidate the distinctions that Grundtvig made in his world of ideas in the course of the years from 1824 to 1834, first between spirit and letter, church and church-school (1826-1830), and then between natural life and Christian life (in 1832). In His "Literary Testament" (1827), Grundtvig himself admits that there was a "Chaos" in his writings, due to the youthful fervour that pervaded his literary works and his sermons in the years 1822-1824. But not until 1832 does he acknowledge that "when I speak or write as a citizen, or a bard, or a scholar, it is not the time nor the place to either preach or confess, so when I have done so, it was a mistake which can only be excused with the all too familiar disorder pertaining to our church, our civic life, and our scholarship...", as it says in a passage omitted from the manuscript for "Norse Mythology”, 1832. (The passage is printed in its entirety in ”A Human first...”, p. 259f.)The point of departure for Thaning’s article is a sermon on the Son of the Widow from Nain, delivered in 1834, which the editor, Christian Thodberg also found "singularly personal”, since Grundtvig keeps using the pronoun ”1”. In this sermon Grundtvig says that those who have heard him preaching on this text before, would remember that he regarded the mourning widow as ”an image of the same broken heart at all times”, and her comforter, Jesus, not only as a great prophet in Israel, but ”as the living Being who sees us and is with us always until the end of the world”. Thodberg is of the opinion that Grundtvig refers to his sermon from 1823. Thaning, however, thinks that the reference is to the sermon from 1824. But Grundtvig adds that one may now rightly ask him whether he ’’still regards the gospel for the day with the same eyes, the same hope and fear as before.” He wants to discuss this, among other things ’’because the best thing we can do when we grow old is ... to develop and explain what in the days of our youth .. sprang up before our eyes and echoes in our innermost mind.” In other words, he speaks as if he had grown old. So Thaning asks: "What happened on the way from Our Saviour’s Church to Frederick’s Church?"Thaning’s answer is that there was a change in Grundtvig’s view of life. Already in his first sermon in 1832, he says that his final and truly real hour as a pastor has now arrived. Thaning’s explanation is that Grundtvig has now passed from the time of strong emotions to that of calm reflections. Not until now does he realize "what is essential and what is not". And in 1834 he says that our Christian views, too, must go through a purgatorial fire when we grow older. This is not only true of the lofty views of human life which, naturally, go through this purgatory and most often lose themselves in it. Here Grundtvig distinguishes between natural and Christian life which is something new in a sermon. Thaning adds that this purgatorial fire pervades Grundtvig’s drafts for the Introduction to "Norse Mythology" in 1832. But then, Grundtvig’s lofty views did not lose themselves in purgatory. He got through it. His view of life changed. (Here Thaning refers to his dissertation, "A Human First...", p. 306ff).This is vaguely perceptible throughout the sermon in question. But according to Thaning Grundtvig slightly distorts the picture of his old sermon. In the latter he did not mix up natural and Christian life. It is Thaning’s view that Grundtvig is thinking of the distinct mixture of Christianity and Danish national feeling in the poem "New Year’s Morning" (1824). But he also refers to Grundtvig’s sermon on Easter Monday, 1824, printed in Helge Toldberg’s dissertation, "Grundtvig’s World of Symbols" (1950), p. 233ff, showing that he has been captured by imagery in a novel manner. He seems to want to impose himself upon his audience. In 1834 he knows he has changed. But 1832 is the dividing year. In the passage omitted from the manuscript for "Norse Mythology", Grundtvig states explicitly that faith is "a free matter": "Faith is a matter of its own, and truly each man’s own matter". Grundtvig could not say this before 1832. Thaning is of the opinion that this new insight lies behind the distinction that he makes in the sermon in 1834, where he says that he used to mix up Christian life with "the natural life of our people", which involved the risk that his Christian view might be misinterpreted and doubted. Now it has been through purgatory. And in the process it has only lost its "absurdity and obscurity, which did not come from the Lord, but from myself”.Later in the sermon he says: "The view is no more obscured by my Danish national feeling; I certainly do not by any means fail to appreciate the particularly friendly relationship that has prevailed through centuries between the Christian faith and the life of this people, and nor do I by any means renounce my hope that the rebirth of Christianity here will become apparent to the world, too, as a good deed, but yet this is only a dream, and the prophet will by no means tell us such dreams, but he bids us separate them sharply from the word of God, like the straw from the grain...". This cannot be polemically directed against his own sermons from 1824. It must necessarily reflect a reaction against the fundamental view expressed in "New Year’s Morning" and its vision of Christianity and Danishness in one. (Note that in his dissertation for the Degree of Divinity, Bent Christensen calls the poem "a dream", as Thaning adds).In his "Literary Testament" (1827) Grundtvig speaks about the "Chaos" caused by "the spirits of the Bible, of history, and of the Nordic countries, whom I serve and confuse in turn." But there is not yet any recognition of the same need for a distinction between Danishness and Christianity, which in the sermon he calls "the straw and the grain". Here he speaks of the distinction between "church and church-school, Christianity and theology, the spirit of the Bible and the letter of the Bible", as a consequence of his discovery in 1825. He still identifies the spirit of human history with the spirit of the Bible: "Here is the explanation over my chaos", Grundtvig says. But it is this chaos that resolves itself, leading to the insight and understanding in the sermon from 1834.In the year after "The Literary Testament", 1828, Grundtvig publishes the second part of his "Sunday Book", in which the only sermon on the Son of the Widow in this work appears. It is the last sermon in this volume, and it is an elaboration of the sermon from 1824. What is particularly characteristic of it is its talk about hope. "When the heart sees its hope at death’s door, where is comfort to be found for it, save in a divine voice, intoning Weep not!" Here Grundtvig quotes St. John 3:16 and says that when this "word of Life" is heard, when hope revives and rises from its bier, is it not then, and not until then, that we feel that God has visited his people...?" In the edition of this sermon in the "Sunday Book" a note of doubt has slipped in which did not occur in the original sermon from 1824. The conclusion of the sermon bears evidence that penitential Christianity has not yet been overcome: "What death would be too hard a transition to eternal life?" - "Then, in the march of time, let it stand, that great hope which is created by the Word ... like the son of the great woman from Nain."It is a strange transition to go from this sermon to the next one about the son of the widow, the sermon from 1832, where Christ is no longer called "hope". The faith has been moved to the present: "... only in the Word do we find him, the Word was the sign of life when we rose from the dead, and if we fell silent, it was the sign of death." - "Therefore, as the Lord has visited us and has opened our mouths, we shall speak about him always, in the certain knowledge that it is as necessary and as pleasurable as to breathe..." The emphasis of faith is no longer in words like longing and hope.In a sense this and other sermons in the 1830s anticipate the hymn "The Lord has visited his people" ("Hymn Book" (Sangv.rk) I, no. 23): the night has turned into morning, the sorrow has been removed. The gospel has become the present. As before the Church is compared with the widow who cried herself blind at the foot of the cross. Therefore the Saviour lay in the black earth, nights and days long. But now the Word of life has risen from the dead and shall no more taste death. The dismissal of the traditional Christianity, handed down from the past, is extended to include the destructive teaching in schools. The young man on the bier has been compared with the dead Christianity which Grundtvig now rejects. At an early stage Grundtvig was aware of its effects, such as in the Easter sermon in 1830 ("Sunday Book" III, p. 263) where Grundtvig speaks as if he had experienced a breakthrough to his new view. So, the discovery of the Apostles’ Creed in 1825 must have been an enormous feeling of liberation for him – from the worship of the letter that so pervaded his age. Grundtvig speaks about the "living, certain, oral, audible" word in contrast to the "dead, uncertain, written, mute" sign in the book. However, there is as yet no mention of the "Word from the Mouth of our Lord", which belongs to a much later time. Only then does he acquire the calm confidence that enables him to preach on the background of what has happened that the Word has risen from the dead. The question to ask then is what gave him this conviction."Personally I think that it came to him at the same time as life became a present reality for him through the journeys to England," Thaning says. By the same token, Christianity also became a present reality. The discovery of 1825 was readily at hand to grant him a means of expression to convey this present reality and the address to him "from the Lord’s own mouth", on which he was to live. It is no longer enough for him to speak about "the living, solemn evidence at baptism of the whole congregation, the faith we are all to share and confess" as much more certain than everything that is written in all the books of the world. The "Sunday Book" is far from containing the serene insight which, in spite of everything, the Easter sermon, written incidentally on Easter Day, bears witness to. But in 1830 he was not yet ready to sing "The Lord has visited his people", says Thaning.In the sermon from 1834 one meets, as so often in Grundtvig, his emphasis on the continuity in his preaching. In the mourning widow he has always seen an image of the Church, as it appears for the first time in an addition to the sermon on the text in the year 1821 ("Pr.st. Sermons", vol I, p. 296). It ends with a clue: "The Church of Christ now is the Widow of Nain". He will probably have elaborated that idea and concluded his sermon with it. Nevertheless, as it has appeared, the sermon in 1834 is polemically directed against his former view, the mixture of Christian and natural life. He recognizes that there is an element of "something fantastic" sticking to the "view of our youth".Already in a draft for a sermon from March 4,1832, Grundtvig says:"... this was truly a great error among us that we contented ourselves with an obscure and indefinite idea of the Spirit as well as the Truth, for as a consequence of that we were so doubtful and despondent, and we so often mistook the letter for the spirit, or the spirit of phantasy and delusion for that of God..." (vol. V, p. 79f).The heart-searchings which this sermon draft and the sermon on the 16th Sunday after Trinity are evidence of, provide enough argument to point to 1832 as a year of breakthrough. We, his readers, would not have been able to indicate the difference between before and now with stronger expressions than Grundtvig’s own. "He must really have turned into a different kind of person", Thaning says. At the conclusion of the article attention is drawn to the fact that the image of the Son of the Widow also appears in an entirely different context than that of the sermon, viz. in the article about Popular Life and Christianity that Grundtvig wrote in 1847. "What still remains alive of Danish national feeling is exactly like the disconsolate widow at the gate of Nain who follows her only begotten son to the grave" (US DC, p. 86f). The dead youth should not be spoken to about the way to eternal life, but a "Rise!" should be pronounced, and that apparently means: become a living person! On this occasion Grundtvig found an opportunity to clarify his ideas. His "popular life first" is an extension of his "a human being first" from 1837. He had progressed over the last ten years. But the foundation was laid with the distinction between Christian and natural life at the beginning of the 1830s.

Tidal flats are a type of coastal space that flood at high tides and are exposed at low tides—not quite land or sea. Distinct from open waters or seabeds, tidal flats’ in-betweenness gives them particular materialities that constantly frustrate our efforts to know them. Inspired by the provocation of recent scholarship on “wet ontologies” while simultaneously recognizing the nuances within water worlds, I argue for the slippery ontologies of tidal flats and explore the implications of this approach. Specifically, this paper shows how tidal flats’ dynamic and ambiguous materialities resist attempts to place them into modern knowledge systems. Drawing upon the particular case of South Korea’s tidal flats, called getbol, I first interrogate the in-betweenness of tidal flats, a major source of their material and conceptual slipperiness. I then discuss the similarities and differences between tidal flats and other types of land–water spaces. Next, through several interviews with those who produce modern scientific knowledge of getbol, I examine how tidal flats’ unique compositions interfere with modernity’s efforts to measure their boundaries, matter, and verticality. I highlight how both non-humans and humans contribute to tidal flats’ slipperiness. Finally, I show how the slippery nature of tidal flats has threatened their survival. In South Korea alone, more than half the tidal flats were removed due to reclamation efforts in the past century. In this context, I contend that fully embracing tidal flats’ slippery ontologies may prevent them from further endangerment.
