Full textAbstract:
Elite varieties of black currant selected at the Federal Agrarian Scientific Centre of the North-East were studied with the purpose of identifying samples with an optimal combination of high productivity, large fruit, good taste, resistance to big bud mite and powdery mildew. The studies were carried out in 2015–2019 on a site located in the central agro-climatic zone of the Kirov region. 10 elite black currant varieties of 2013 planting were investigated. The varieties of Arkadiya and Vologda were used as control. The counts and observations were carried out using conventional methods. The combination of high productivity, its sustainability and high self-fertility was noted in varieties 71-2-07, 65-1-07 and 64-4-07. In terms of resistance to the pest, two highly resistant samples 71-2-07 and 65-1-07 were identified, which showed no signs of damage during the study period. The damage by big bud mite remained low across the entire experimental site. The average negative effect of big bud mite on the yield was found (r = -0.48). In the following 7 elite forms — 71-2-07, 65-1-07, 70-5-07, 46-1-07, 12-1-07, 15-1-07, 20-1-07 (70.0 % of the studied material), the maximum degree of damage by powdery mildew did not exceed 1.0 points, which indicates their high resistance. The combination of high resistance to big bud mites and resistance to powdery mildew was found in varieties 71-2-07 and 65-1-07. During the study period, 9 elite black currant varieties produced large-fruited berries. Out of these 9 forms, 3 (71-2-07, 64-4-07, 12-1-07) showed significantly higher values of this indicator compared to the Vologda control. Sample 27-1-07 was distinguished by a combination of large fruit, good taste and low acidity, as well as by high contents of ascorbic acid and dry matter. Sources of economically valuable traits were identified in 2 samples: 65-1-07 having a combination of high productivity, large fruit, high self-fertility, good taste, resistance to big bud mites and powdery mildew; 64-4-07 having a combination of high productivity, large fruit and high self-fertility. These genotypes can be recommended as a starting material for further breeding. On the basis of the results obtained, the Ariel variety (71-2-07) was forwarded to the State Variety Testing in 2020.

AbstractThe biology and phenology of the yew big bud mite, Cecidophyopsis psilaspis (Nalepa, 1893), were studied on Pacific yew, Taxus brevifolia Nutt., in British Columbia, Canada. The mite showed the typical life cycle of eriophyoids on evergreen hosts, with all stases being present throughout the year. The numbers of C. psilaspis, which colonized both vegetative and reproductive buds, peaked in May to August, with the lowest numbers in March and October and the highest numbers in June. Mite numbers differed among bud types, with averages following the sequence terminal buds = lateral buds > male reproductive buds > axillary buds > female reproductive buds > latent buds. Very few mites were found in latent buds except during bud formation, when other vegetative buds were unavailable. Reproductive buds were colonized mostly from May to July. There was no evidence of arrhenotoky in C. psilaspis, as the proportion of mites that were females ranged from 54% to 100%. Temperature and predation were considered the likely factors that determine population fluctuations. It was hypothesized that C. psilaspis abundance increased following favorable spring temperatures and new food resources, whereas predation by other mite species and lower temperatures, which prolonged development, were responsible for the low numbers in March and October.

Evaluation of bids by WG ULP has an important role in the selection of providers of construction work to determine the potential winner. A group decision support system is a system that can help the Working Group ULP Bali provincial government in making decisions with the ability to analyze the construction work provider selection criteria with AHP and Borda method. With GDSS bid evaluation, all members of the Working Group can evaluate the ULP provider offering construction work optimally based on the criteria of administrative, technical prices so as to improve the quality of the repair process of group decision-making. Both methods are used because there are two stages in the decision-making that decision of individual and group decision. The test results show that the system can be applied GDSS as decision support systems in the bid evaluation provider of construction work and decided the company's most worthy to be a winner

Full textAbstract:
AbstractThe Peak District is an upland region in central Britain with a rich mining geoheritage. It was established as the UK’s first National Park in 1951. It was the region, due to its widespread loss quarries and mines sites to inappropriate remedial measures, which led to the recognition and promotion of the modern geotourism paradigm. It is the birthplace of British geotourism with the earliest recorded instances of leisure travellers purposefully choosing to visit mines and caves. Metalliferous mining in the region can be traced back to the Bronze Age. Gangue minerals, especially fluorspar and barites, later became significant primary extraction activities and underpinned a small-scale semi-precious stone industry. It is home to the World Heritage inscribed site of the Derwent Mills, significant in the development of early Industrial Revolution textile technology and manufacturing practices. The almost equally significant mining geoheritage has yet to be similarly recognised and, indeed, its survival is still threatened because most tourism and many mining geoheritage stakeholders have a limited understanding of geo-history and the geo-interpretive significance of the individuals and geosites that shaped historical geotourism and geological exploration in the Peak District; their exploits and the legacy of their publications, alongside its superbly exposed and well researched geology and associated mining geoheritage, could underpin a bid for the region’s recognition as a geopark. Hence, this introductory paper summarises the key aspects of the region’s geology and major mining geoheritage sites, together with the major works and influence of some key individuals that should be included as a very minimum in such a bid.

Efficacy and Safety of Oral Sulopenem Etzadroxil/Probenecid Versus Oral Ciprofloxacin in the Treatment of Uncomplicated Urinary Tract Infections (uUTI) in Adult Women: Results from the SURE-1 Trial."

Full textAbstract:
Abstract Background Sulopenem is a broad-spectrum IV and oral penem antibiotic being developed for the treatment of infections caused by multidrug-resistant bacteria. Overall and Clinical Success in Patients with an Uncomplicated UTI at Test of Cure (TOC) and End of Treatment (EOT) Methods 1,671 adult women with pyuria, bacteriuria, and signs and symptoms of uUTI were randomized to sulopenem etzadroxil/probenecid bid for 5 days or ciprofloxacin bid for 3 days. Two independent primary analyses, each with a separate alpha assigned, were incorporated into the design of the study with the primary endpoint being overall success (combined clinical and microbiologic success) at the Test of Cure (TOC) visit. In the micro-MITTR population (patients with baseline pathogen resistant to ciprofloxacin), sulopenem was compared for superiority over ciprofloxacin; in the micro-MITTS population (patients with baseline pathogen susceptible to ciprofloxacin), the two agents were compared for non-inferiority. Using a pre-specified hierarchical testing procedure (Westfall 2001), the primary efficacy endpoint was then to be further tested if either superiority or non-inferiority was declared in the MITTR or MITTS populations, respectively. Results In the micro-MITTR population, sulopenem demonstrated superiority to ciprofloxacin (p < 0.001). In the micro-MITTS population, sulopenem was not non-inferior to ciprofloxacin for the primary endpoint, driven primarily by the higher rate of asymptomatic bacteriuria post treatment in patients on sulopenem. In the combined analysis of all randomized patients with an organism identified at baseline (MITTR+MITTS), sulopenem was non-inferior to ciprofloxacin. Treatment emergent adverse events occurred more frequently in sulopenem patients (all, 24.8% vs 13.9%; related, 17.0% vs 6.2%), accounted for by a higher incidence of self-limited diarrhea (12.4% vs 2.5%). Serious adverse events were similar on each regimen. Conclusion Sulopenem was superior to ciprofloxacin for the treatment of adult women with uUTI due to quinolone non-susceptible pathogens. Sulopenem was not non-inferior in the treatment of quinolone susceptible pathogens, driven by a lower rate of asymptomatic bacteriuria in patients receiving ciprofloxacin, but was non-inferior in the combined population of patients.

Purpose. Evaluate safety and efficacy of topical lotilaner ophthalmic solution, 0.25% for the treatment of Demodex blepharitis. Patients and Methods. 15 patients with Demodex blepharitis, defined as >10 collarettes on the upper lid, lid margin erythema, and Demodex density of ≥1.5 mites/lash on microscopy, were treated bid for 28 days with lotilaner ophthalmic solution, 0.25%. Contact lens wear, artificial eyelashes, and lid structural abnormalities were among the exclusion criteria. No other antibacterial, antiparasitic, or anti-inflammatory treatment or lid hygiene products were permitted. Patients were assessed on Days 7, 14, 28, 60, and 90. Outcome measures were changes in collarette grade and mite density on Day 28. Adverse events and changes in intraocular pressure (IOP), corrected distance visual acuity (CDVA), and slit-lamp biomicroscopy were assessed. Results. Mean collarette grade (upper lids) improved from 3.07 ± 0.21 to 0.79 ± 0.19 on Day 28; the change was statistically significant for both upper and lower lids from Day 14 on. Mean mite density per lash decreased from 2.28 ± 0.16 at baseline to 0.14 ± 0.05 at Day 28 p < 0.0001 . Mite eradication (0 mites) was documented in 57.1% of eyes. The effects were durable through Day 90. There were no adverse events and little to no change in CDVA or IOP. The drop was well tolerated, with no discontinuations due to ocular irritation. Conclusion. Topical lotilaner ophthalmic solution, 0.25% for 4 weeks, showed promising efficacy for the treatment of Demodex blepharitis. This novel treatment appears to be safe and well tolerated. Randomized controlled studies are needed to confirm the results.

Juan, a literate black slave born and raised in the Spanish town of Cáceres, labored for at least five years during the 1560s in the Honduran gold mines of Guayape. Finally, growing tired of the arduous work of placer mining and taking advantage of his isolation, he made a bid for freedom. Upon hearing of Juan's flight, his owner, a wealthy Santiago-based merchant named Santos de Figueroa, immediately began the process of securing Juan's recovery. Eventually Juan made his way to Santo Domingo where unfortunately he was captured and Figueroa notified of his whereabouts. It remains unknown if Juan was actually returned to Santiago or if Figueroa instead preferred to sell him, a rather common occurrence in cases of runaway slaves.

Eriophyoid big bud mites are key pests of hazelnuts throughout the world, although little is known of the identity and impact of the species on New Zealand hazelnut crops. The key objectives of this study were to determine the species of mite present on New Zealand crops, explore a method of monitoring mite emergence from overwintering big buds, determine the phenology of mites in relation to tree phenology and weather, and identify the optimum timing for control measures. The presence of both Phytoptus avellanae (Nalepa 1889) (Acari: Phytoptidae) and Cecidophyopsis vermiformis (Nalepa 1889) (Acari: Eriophyidae) was confirmed, the latter species being a new record for New Zealand. Preliminary diagnostic DNA sequences were determined for both species. A sticky band technique was developed to monitor mite emergence from overwintering big buds, and mite emergence was found to occur between early and late spring. Mite emergence and movement occurred when daily temperatures were greater than 15 degrees C and when mean temperatures were greater than 9 degrees C, with mite emergence increasing with temperature. It proved difficult to relate the phenology of hazelnut to mite emergence, however, the development of new buds during mite emergence was a crucial factor in the infestation of new buds. An accumulated heat sum model (DD), started at Julian date 152 and using a lower threshold temperature of 6 degrees C, predicted the onset of emergence on two cultivars and at two sites as occurring at approximately 172 DD. A regression model based on leaf number, bud height, bud width, DD and Julian date provided a more satisfactory prediction of percent accumulated mite emergence. It is recommended both peak mite emergence and the appearance of hazelnut buds should be used to optimise the time to apply control measures. Therefore, a control should be applied before buds measure 0.5 x 0.5 mm (width x height), are enclosed within the axil, and have a rounded tip, or, when 50% accumulated mite emergence has occurred, which ever occurs first. A preliminary field experiment tested the application of sulphur (40 g/10 litres of 800 g/kg No Fungus Super Sulphur) at 2, 50 and 80% accumulated mite emergence. The greatest reduction in mite numbers was achieved with an application at approximately 50% emergence. Considerable variation in mite emergence occurred between years, therefore optimum timing of controls would need to be determined by monitoring mites, new buds and weather conditions each year. Field collection of mites also identified the presence of Typhlodromus doreenae Schicha (Acari: Phytoseiidae) which would warrant further study for inclusion in an integrated mite control programme.

Full textAbstract:
For seventy miles along California’s central coast stretches an exceptional landscape known as Big Sur. Looming mountains, precipitous cliffs, deep canyons, towering redwoods, abundant wildlife, and an expansive ocean are all defining features of this prized coastline. Big Sur’s timeless landscape compelled California legislators to cater to the growing auto-tourist demand of the 1920s by penetrating the isolated Big Sur with the Carmel–San Simeon Highway, later known as Highway 1. For over seventy-five years, this ribbon of road, etched into the Santa Lucia Mountains, has delivered millions of admirers to the dramatic Big Sur coastline. They seek contact with a landscape that possesses qualities similar to those of a national park, but they also come to Big Sur because it has long been a cultural symbol of California and the West, a place rife with meaning in contemporary society. Big Sur’s pioneering preservation model—developed by residents and local and state officials—is key to its mystique. Big Sur occupies a hybrid space somewhere between American ideals of development and wilderness. It is a space that challenges the way most Americans think of nature, its relationship to people, and what, in fact, makes it “wild.”

This chapter focuses on Chicago in the 1850s, which had been thriving but remained an unspectacular frontier town and the unglamorous home of thirty thousand residents and miles of mud. It mentions the Swedish novelist Fredrika Bremer who described Chicago as one of the most miserable and ugliest cities she has yet seen in America, which she observed during her visit in 1853. The chapter talks about Chicago's population that would grow to 1.7 million, making it the second largest city in the United States. It points out the observation made by the French political scientist Emile Boutmy in the late 1800s regarding the United States as primarily a commercial society and only secondarily a nation. It also investigates how Chicago emerged as the preeminent “commercial company” in the world between 1850 and 1900.

On May 17, after his army was defeated at the Battle of the Big Black River, Confederate General John C. Pemberton ordered a retreat back to the city of Vicksburg. He had just been humiliated by Union General Ulysses S. Grant, who, through rapid marching, staying one step ahead of his adversary, had defeated Confederate forces in four pitched battles. The Federals had captured sixty-five pieces of artillery, took out of action 14,000 Confederate troops, and most important completely turned the tide in their long and frustrating campaign against Vicksburg. As the beaten Confederates streamed into the city panic ensued among the residents. But Pemberton carefully placed two fresh divisions already holding Vicksburg at key places along the line of earthworks that protected the eastern approaches to the town while placing the demoralized veterans of his recent battles in less risky positions. Delayed by having to construct crossings of the Big Black River, Grant’s Federals did not pursue until May 18 but they had all the advantages now on their side. Many expected to enter Vicksburg as soon they marched the fifteen miles separating the Big Black River from the city that become the Gibraltar of the Confederacy.

What happens when an asteroid hits the deep ocean? The public has been assailed with Hollywood’s interpretations such as the movie Deep Impact, but the reality is worryingly real. Approximately 2.5 million years ago, the only know deep-ocean asteroid struck the South Pacific. Initial waves were miles high. It resulted in the extinction of 36% of all life on Earth, including the megashark. The megalodon, or megashark, was big and fast. It preyed upon many cetacean species, such as dolphins and small whales. As a result of the asteroid impact, meter-thick bone beds of dead animals were washed up along Pacific shores, but perhaps even worse, climate changed.

The mochilla lay beside the migrant trail, an abandoned black daypack still heavy with goods. The Border Patrol agent carried it to the shelter of a corner of rocks, where no one could spot him while he searched it. He dug through the contents. There was a package of refried beans in gaudy plastic, a bag of instant oatmeal, fruit punch in a bottle too small to slake a serious thirst, and other convenience food. Also a half-pound or more of white grains in a punctured bag; the agent wet a finger and tasted: only sugar. Then he heard voices approaching and scrambled up the slope to hide in the brush. There were three of them: a rangy young man with a shadowy face in the lead, an older guy in a ball cap, and a pretty young woman with raven hair behind. They were Americans, not migrants or narcos. Their skin, their clothes, even their posture gave them away. They were too relaxed, too careless to be anything else. The agent stepped out from his hiding place. They slowed but did not stop. “You all out hiking?” “Yep,” said the young man with the shadowy face. “Where you from?” “Tucson,” came the clipped reply. Then the hikers, unsmiling and eyes straight ahead, passed him at a fast clip, the chill of the encounter resisting the afternoon heat, the desert absorbing the silence. The hikers had come from the direction of the Rat’s Nest, a maze of drainages half a dozen miles above the Line, and they disappeared toward Apache Pass—not the famous Apache Pass in the Chiricahua Mountains in eastern Arizona, but a lesser pass on the shoulder of Bartolo Mountain, well south of Tucson and only nine or ten miles north of Mexico. The agent knew they weren’t out for a hike. No one comes just to hike in the contorted and contested, bone-dry mountains along this stretch of the border. Everyone has a purpose. They come to smuggle or to be smuggled. They come to scurry in moonlight and to drag themselves under the blaze of the sun across dozens of miles of steep shadeless rock.

Communities who happen to live where there is potential for big money to be made from mining the resources from under their feet, face a daunting set of challenges. Many people are saying ‘No’ to mining capital, and many communities are divided. We consider the thinking and praxis of militants from a number of areas in the province of KwaZulu-Natal (South Africa) who are thinking resistance to a wave of real and prospective new coal mining initiatives. We conclude that this irruption of the “No” is simultaneously powerful and fragile. It is the assertion of the human life of the people against the forces of death. Provided the struggle that unfolds remains faithful to the fundamental 'No' that originated it, then it stops simply reproducing or modestly-reforming that world as-it-is, but instead marks out an emancipatory future of what could be.

Model’s City’s demise did little to slow industrial growth in Niagara Falls. During the early 1900s, the region’s economy expanded at a tremendous rate. Niagara’s next big thing came in the form of chemicals. When William Love departed the area, the Falls claimed no major chemical maker. By the 1920s, Niagara Falls was home to a dynamic and thriving chemical sector that produced huge amounts of industrial-grade chemicals via hydroelectric power. By World War II, dozens of companies called Niagara Falls home, making it a global leader in the production of chlorines, degreasers, explosives, pesticides, plastics, and myriad other chemical agents. The chief architect of Niagara’s chemical expansion was Elon Huntington Hooker, an engineer turned industrial titan who settled in the Falls soon after William Love left. [ Fig. 6 ] Hailing from famous families, Hooker was destined for great things. On one side, Hooker could trace a lineage back to Puritan divines who had literally built cities on a hill; on the other, there were railroad titans who had traversed the American West. In both cases, Elon Hooker’s family background inspired him to think big. The guiding spirit of a brash new chemical company that bore his surname, Hooker harnessed Niagara’s power to become the nation’s leading producer of two key chemicals: chloride of lime (bleaching powder) and sodium hydroxide (caustic soda). Over the next fifty years, Hooker Chemical became a mainstay of American industry. Its products helped win wars, explore space, and fuel American consumerism. These developments would not surprise Elon Huntington Hooker. Indeed, he thought of himself as an American Adam: a technological originator who reshaped nature and society in equal measure. His vision of chemical superiority would come to fruition a few miles from Love’s abandoned canal—at first glance, perhaps nothing more than a coincidence of history.

Full textAbstract:
Wealth, or capital, tends to be represented in the earliest Holmes stories in the reassuringly familiar form of specie (coins and notes), or precious stones or metals. The Agra treasure in The Sign of Four, the French gold in ‘The Red-Headed League’, the Australian gold mines of ‘The Boscombe Valley Mystery’ (1891) and the American gold mine of Hatty Moran’s father in ‘The Noble Bachelor’, the 421 pennies and 270 half-pennies in ‘The Man with the Twisted Lip’ (1891), the blue carbuncle, the counterfeit half-crowns in ‘The Engineer’s Thumb’, the fifty thousand pounds in notes loaned to the illustrious client in exchange for a priceless piece of jewellery in ‘The Adventure of the Beryl Coronet’ (1892) – all are examples of the most solid forms of capital. Even the opium den in ‘The Man with the Twisted Lip’ is named ‘The Bar of Gold’. Several of these stories belong to a tradition of narratives, stretching back to Chaucer’s tale of the Pardoner but including such favourites of Doyle’s as Collins’s The Moonstone and Edgar Allan Poe’s ‘The Gold Bug’ (1843), in which great wealth in material, tactile form motivates characters to perform extraordinary feats.

Since the introduction of sweet oranges to Florida with the establishment of the settlement at St. Augustine in 1565, the citrus industry has been steadily moving south. Prior to the “big freeze”, of 1894–95, the main citrus growing region was the hammocks of north-central Florida. The major citrus producing counties in the 1890’s were Orange, Alachua, Volusia, Lake, Putnam, Hillsborough, Pasco, Brevard and Polk, in that order. In 1889–90, Alachua county accounted for about one-third of the total citrus production. The freezes of the 1890’s caused the citrus belt to move south a hundred miles or so. By 1955, the leading counties were Polk, Lake, Orange, Hillsborough, Indian River, Highlands, Brevard and Volusia. Due to the strong influx of new residents in the 1950’s, the best drained areas along the coasts and central portion of the state were being converted to residential sub-divisions. Citrus growers were forced into less desirable locations. An attempt was made to expand citrus plantings along the upper west coast, but the winters of 1957–58 and 1962–63, with their severe freezes, again forced the industry south. The latest freezes of 1977 and the mid-1980’s have had a profound effect on the industry. In 1986–87 the major citrus producing counties were Polk, St. Lucie, Indian River, Highlands and Hendry. Lake County produced 40 million boxes of fruit in 1975–76 and less than 2 million in 1986–87. The most recent freezes have renewed interest in the undeveloped pastureland of southwestern Florida. As of January, 1988, 300 square miles of citrus have been permitted in Hendry, Glades, Collier and Lee Counties. Applications for another 100 square miles are pending.

Full textAbstract:
There have been papers that analyze the relationship between bit design and a bit’s vibrational characteristics. These papers typically are based on the analysis of three-axis near-bit down-hole vibration sensors. In this paper, the authors take a simpler approach. Using a standard microphone literally pointed at the bit, they record the noise of the bit/rock interaction while drilling and analyze the resulting noise for these but vibrational characteristics. The data were gathered at the Colorado School of Mines in Golden, Colorado. The noise of a PDC core, roller cone, and diamond core bits were recorded under various weight and rotary speeds using a microphone and a vertically mounted uniaxial geophone (used for confirming the data recorded on the microphones). Using a Fast Fourier Transform, the frequency spectra were extracted from the recorded data and analyzed. The data was normalized for rotational speed. The results of the frequency analysis of the roller cone, the PDC, and the natural diamond bits are presented in this paper. The major differences in the three bit frequency characteristics could be detected and furthermore, for drag bits, the frequency characteristics could be related to the bit’s design. The frequency spectra of the roller cone bit can best be described with a general high amplitude level that is relatively evenly distributed over the whole frequency spectrum. The drag bit data showed a strong relationship between the number and arrangement of cutting elements and frequency peaks on a plot of amplitude vs. cycles per revolution. Frequency peaks were observed at multiples of the number of cutting elements. In general this relationship was strongly visible on the PDC bit data but not as strongly visible on the diamond bit data. The conclusion is that bit characteristics can be determined using only the noise of a bit. Potential applications of this research include detecting and diagnosing bit problems (e.g. broken teeth, bit balling) in real time using simple microphone based acoustic data.

Full textAbstract:
This paper examines the potential of a bi-stable von-Mises truss (VMT) connected to viscous damping elements in absorbing impact loads, and reducing loads and accelerations transmitted to the base. A compact sandwich-panel-like element is designed, fabricated and tested in an impact testing machine which comprises of a top plate, a bottom plate, and VMTs in-between that stroke the dashpot as they snap through. The loads transmitted to the bottom plate showed reductions of over 70% for lower drop heights, while reductions approaching 50% were seen for larger drop heights. The introduction of pre-loaded springs in parallel to the VMTs resulted in the prototype not snapping through, except at the largest drop heights tested. The reductions in the transmitted loads were modest for small drop heights but improved as the drop heights increased and snap through occurred. Accelerations transmitted to the bottom plate also showed reductions of 83–88% relative to the upper plate accelerations. A Simscape model of the system showed good overall agreement with tests for loads transmitted to the bottom plate when using the measured loads on the top plate as an input.

Full textAbstract:
Abstract Federal regulations require the installation of refuge alternatives (RAs) in underground coal mines to ensure miners’ survivability after a fire or an explosion where escape is impractical or even impossible. Both fires and explosions can generate dangerous or even lethal levels of carbon monoxide (CO) in a mine. As part of their function, RAs must be able to isolate miners from a CO-contaminated mine environment and to purge any CO that might enter the RA as miners enter it. In 2018, researchers from the National Institute for Occupational Safety and Health (NIOSH) conducted purging research in a built-in-place (BIP) RA with a borehole air supply by testing 12 different mixing ventilation system configurations (MVSCs). Recently, NIOSH researchers evaluated the use of a thermal displacement ventilation system configuration (TDVSC) to purge a 60-person BIP RA using a borehole air supply. As in previous research, NIOSH researchers tested the TDVSC with the flow rates of 750 SCFM and then 1,000 SCFM. For each of the flow rates, the results showed that the average purge time for the more expensive TDVSC is within two minutes of the average purge times of previously tested MVSCs. Manufacturers can use this information to not only pursue 30 CFR Part 7 approval from the Mine Safety and Health Administration (MSHA), but also to determine the most practical method to purge contaminants inside RAs.

Full textAbstract:
This paper will propose a concept of efficiently capturing the power of ocean waves. Many concepts have been pursued for over 100 years, but none have proven to be commercially viable for widespread operation. The waves offer 2 to 3 million megawatts of clean, renewable energy globally with up to 65 megawatts available per mile of coastline in favorable locations; furthermore, 60% of the world’s population lives within 100 miles of a coastline. Developing a cost-competitive system offers the potential to contribute to the world’s growing energy needs while preserving the environment. The proposed concept is designed to overcome the difficulties of competing concepts by preventing system destruction due to severe storms and bio fouling — the degradation of precision components in a corrosive environment. The author has developed a working model that has been deployed in the ocean, constructed of “low tech” building materials that demonstrated continuous turning of a large flywheel, moment of inertia of 250 kg m**2. The patented concept offers a means for rapidly constructing the energy capture mechanism and keeping the critical precision components protected from the ocean environment. Building on this success, a large-scale demonstration is proposed to assess performance of a commercially viable configuration.

In ASME Turbo Expo 2018: Turbomachinery Technical Conference and Exposition. American Society of Mechanical Engineers, 2018. http://dx.doi.org/10.1115/gt2018-76449.
Full textAbstract:
The heat transfer characteristics in a rotating pin-fin roughened rectangular channel with an aspect ratio of 4:1 is investigated, simulating a rotor blade trailing edge. The copper plate regional average method is used to determine the heat transfer coefficient. A second inlet is added at the inner top corner of the traditional one-inlet cooling channel to improve heat transfer in the high radius region. Coolant from these two inlets mixes in the middle of the channel, and then exits through eight sidewall slots. The channel is assembled in a rotating facility, and the symmetrical plane of the rectangular channel is orientated at an angle of 135° with respect to the rotation plane. The mass flow rate of the bottom inlet is kept at a constant (Re1 = 20,000), whereas the inlet mass flow rate ratio (MR, second inlet mass flow rate/bottom inlet mass flow rate) changes from 0 to around 0.55. Results show that the second inlet improves the heat transfer in the proximity of the second inlet extensively, but the overall averaged heat transfer is decreased a bit compared to the one inlet channel. Moreover, with the local MR, the heat transfer data at different locations converge into the same trend, indicating that the local MR should be a good parameter in describing the flow in this pin-fin cooling channel. In the rotating one-inlet channel (MR = 0), a critical Ro phenomenon is observed. After the critical point, rotation stops decreasing heat transfer and starts to elevate it. A lower critical Ro is observed at higher radius location but the corresponding local Ro is a constant at around 1.0. In rotating two-inlet channel, the overall heat transfer enhancement caused by rotation is almost in the same level with different MR, indicating that high MR cases (MR > 0.2) is not recommended because the coolant from the second inlet is not efficiently used.
