Abstract:
Abstract BACKGROUND AND IMPORTANCE: Spinal extradural arteriovenous fistula (SEDAVF) with parenchymal drainage (type A) is a rare clinical entity that causes venous congestive myelopathy. Treatment includes endovascular and open microsurgical interventions. We reviewed the clinical records of patients treated for a type A SEDAVF to evaluate the feasibility of our treatment strategy. CLINICAL PRESENTATION: Between 2004 and 2010, 5 patients with a type A SEDAVF were treated at our institutes (4 men and 1 woman; mean age, 60 years). We performed endovascular transvenous embolization (TVE) when lesions were accessible transvenously; otherwise, microsurgical perimedullary drainer occlusion was performed. Follow-up ranged from 23 to 94 months (mean, 45.8 months). One patient was treated with TVE, and the remaining 4 were treated with microsurgical drainer occlusion. After a simple intradural drainer occlusion, an epidural venous lake was completely thrombosed in 2 patients. In 1 patient, postoperative angiography revealed that a part of the epidural component had persisted; however, the patient has been asymptomatic. In the remaining case with multiple intradural draining veins, sole drainer occlusion was not sufficient. A second surgery was required to meticulously coagulate the venous lake. As a consequence, parenchymal drainers disappeared. Overall, all patients stabilized or improved neurologically and experienced no recurrence. CONCLUSION: To treat a type A SEDAVF, either TVE or microsurgical intradural drainer occlusion can be used for satisfactory long-term results with minimal surgical risks. For a case with multiple intradural draining veins, detachment of the venous lake should be considered.

Abstract:
A 40-year-old male suffered transient global amnesia and was diagnosed as having a very rare location of dural arteriovenous shunt (dAVS) involving the right sphenoparietal sinus. The feeding pedicles of dAVS were not only arising from the right external carotid system, including the middle meningeal artery, but also the right internal carotid system including the ophthalmic artery. The dAVS drained into the right sphenoparietal sinus, right vein of Labbe, and right basal vein of Rosenthal through numerous dilated temporal cortical veins. The arteriovenous shunt itself was located at the dura around the right superior ophthalmic fissure and a large varix received direct shunting blood flow from the right sphenoparietal sinus. The dAVS was cured by drainer clipping following transarterial embolisations. A dAVS with cortical venous drainage is considered to have a higher risk of haemorrhage and venous infarction than the others and thus warrants treatment even if the clinical symptom is minimal. If the dAVS has a single drainer, it will be easily cured by way of drainer clipping. Preoperative embolisation makes clipping easier and safer. Intraoperative angiography is useful because preoperative angiography may not necessarily show the complete angioarchitecture around the lesion.

Abstract:
We report on the case of a huge varix that developed after the endovascular embolization of a cerebellar arteriovenous malformation (AVM) with a single drainer. A 21-year-old male presented with trigeminal neuralgia which was caused by the dilated drainer of the AVM. A varix was found at the basal vein of Rosenthal 2 months after an initial stage of embolization with polyvinyl alcohol particles; it diminished after the surgical extirpation of the AVM The varix formation might have been facilitated by the stenosis in the vein of Galen and by the dynamic changes that followed the embolization This rare complication should be kept in mind when embolization is performed for AVMs with impaired venous outlets

Abstract:
Les reseaux de drainage peuvent etre victimes d'accidents de fonctionnement compromettant leur perennite. Un des accidents les plus graves concerne le colmatage mineral des drains, c'est un phenomene irreversible. Il existe des criteres granulometriques pour la prevision du risque de colmatage mineral des drains agricoles, mais leurs limites ont ete souvent mises en evidence par la pratique du drainage. Prevoir le risque de colmatage mineral des drains implique le connaitre et de comprendre le comportement du sol pres du drain. Trois grands types de phenomenes ont ete mis en evidence a l'interface sol/drain: l'organisation des ecoulements dans le sol a l'approche du drain, l'action de l'eau en mouvement sur le sol traverse, le cycle sedimentation/erosion/transport des particules de sol a l'interieur du drain. Seuls les deux premiers phenomenes sont abordes dans la presente etude; ils permettent de comprendre la premiere partie du colmatage mineral interne des drains, c'est-a-dire la penetration de particules de sol par les perforations. Une serie d'experiences en cuve de sable couplee avec un modele numerique aux elements finis permet de visualiser l'organisation de l'ecoulement a l'interface sol/drain et de connaitre les valeurs maximales atteintes par le gradient hydraulique, donc d'evaluer les forces hydrodynamiques qui s'exercent sur les partiucles de sol. Parallelement, un test a ete mis au point qui permet d'evaluer la resistance des sols a l'action de l'eau s'ecoulant vers les perforations du drain. Les resultats des tests associes a des donnees de terrain permettent de proposer une typologie des comportements des sols

O presente trabalho estudou o comportamento de rejeitos de minério de ferro e de ouro, reforçados com fibras de polipropileno, com o objetivo da aplicabilidade destes compósitos em aterros (pilhas) de rejeitos de mineração. As fibras foram distribuídas de forma aleatória nos rejeitos (matriz) em um teor de 0.5 por cento em relação ao peso seco da matriz. Os rejeitos de minério de ferro e de ouro são classificados como uma areia siltosa e uma argila siltosa, respectivamente. O programa experimental consistiu em ensaios triaxiais convencionais drenados e não drenados (tensões efetivas de confinamento de 50, 100, 200 e 400 kPa) em amostras não reforçados e reforçados com fibras. Ensaios de cisalhamento direto com superfície polida (tensões normais de 25, 50, 100, 200 e 400 kPa) foram realizados para determinar a influência do reforço na fase residual dos compósitos. Ensaios de Microscopia Eletrônica de Varredura (MEV) foram realizados para visualizar a interação fibra-matriz. A análise global dos resultados permitiu mostrar que fibras de polipropileno não modificam o comportamento elastoplástico do rejeito de minério de ferro, porém no rejeito de minério de ouro o comportamento muda para elastoplástico de enrijecimento. A resistência ao cisalhamento incrementou em ambos os rejeitos reforçados, com um ganho mínimo equivalente ao dobro da tensão cisalhante dos rejeitos sem reforço. Com relação à variação volumétrica, o rejeito de minério de ferro apresenta um comportamento dilatante e a adição de fibras incrementa esse comportamento. No rejeito de minério de ouro observa-se que a tendência volumétrica inicial é de contração e depois apresenta uma leve dilatância, porém, com a adição de fibras, o comportamento dilatante é eliminado. Em conclusão, a aplicabilidade das fibras de polipropileno se mostra como alternativa de reforço e melhoria do comportamento geotécnico dos rejeitos de mineração estudados.
The objective of this work is to study the behavior of iron and gold mine tailings reinforced with polypropylene fibers with the objective of the applicability of these composites in landfills (piles) of mine tailings. The fibers were randomly distributed in the mine tailings (matrix), where was used a content of 0.5 percent in relation to the dry weight of the matrix. The iron and gold mine tailings are classified as a silty sand and a silty clay, respectively. The experimental program consisted of conventional drained and undrained triaxial tests (effective confinement stresses of 50, 100, 200 and 400 kPa) in non-reinforced and reinforced samples. Direct shear tests with a polished surface (normal stresses of 25, 50, 100, 200 and 400 kPa) were performed to determine the influence of reinforcement on the residual phase of the composites. Scanning Electron Microscopy (SEM) tests were performed to visualize the fiber-matrix interaction. The global analysis of the results allowed to show that polypropylene fibers do not modify the elastoplastic behavior of the iron mine tailings, but in the gold mine tailings the behavior changes to the strain hardening elastoplastic. Shear strength increased in both reinforced tailings, with a minimum gain equivalent to twice the shear stress of non-reinforced tailings. The strength parameters in the drained, undrained and residual condition of both mine tailings were increased with the addition of fiber. Regarding the volumetric variation, the iron mine tailings exhibits a dilative behavior and the fiber addition increases this behavior. In the gold mine tailings, it is observed that the initial volumetric tendency is contractive and then presents a slight dilatancy, however, with the fiber addition, the dilative behavior is eliminated. In conclusion, the applicability of the polypropylene fibers is showed as an alternative of reinforcement and improvement of the geotechnical behavior of the studied tailings.

Abstract This paper discusses the testing of a robotic mechanism for cleaning trench drains. The robot runs and operates inside the drain and cleans it without interfering with the surrounding traffic or the drain itself. The robot combines a three-step cleaning process to achieve maximum efficiency in cleaning of the drains. This three-step process includes breaking the dirt down inside the drain, sucking the dirt out of the drain, and transporting it to a collection unit. There is a drive system to move the robot inside the drain. The drive is bidirectional to control the robot motion as required. The robot also has a suction tube and cutting assembly with cutting arms to better facilitate the suction. The cutting arms have metal brushes installed, the rotation of which loosen the debris and push it towards the drain surface. Over the course of developing this robot, two prototypes were designed and built. All aspects relating to the fabrication and testing of the robot prototypes will be discussed in this paper.

Abstract:
Abstract A drain cover for swimming pools, spas and hot tubs has been designed which addresses eight hazards associated with conventional drain systems. This new drain cover, illustrated in Figure 1, eliminates hair entanglement, child evisceration and finger entrapment as well as minimizing body entrapment. Furthermore, its design and construction provide effective countermeasures against vandalism, broken drain covers, missing drain covers and structural deterioration due to environmental antagonists. Additional features unrelated to safety include a universal fastening system which adapts the cover to all circular main drains available in the United States. Also, the drain cover is an order of magnitude stronger than its competitors and has a safe flow rate that is 37% greater than its nearest competitor’s. The product has been manufactured using a PVC material that is the most resistant formulation currently known for counteracting the effects of ultraviolet radiation and chlorine and other chemicals typically found in pools. This paper presents an anatomy of the product’s development.

Abstract This paper discusses the design and conceptualization of a novel robotic mechanism to clean the trench drains. It describes a different approach for drain cleaning with lesser human intervention and more safety to personnel involved. The robot is designed and built to be 4 inches in width and operate entirely within the limited space inside the drain. To achieve a wholesome cleaning process, the entire robot is modular in design and consists of a drive system, a suction tube and a cutting arm assembly with metal brushes installed onto it. The bidirectional drive system enables the robot to move through drain segments repeatedly for optimal performance. The purpose of the cutting arm assembly is to aid the removal of dirt from the drain. In order to improve the robot performance, two prototypes were designed and built. The overall design and modularity of both robot prototypes will be discussed in detail in the paper.

Abstract:
Abstract Turbomachines with large & heavy rotors have journal bearings that utilize thin hydrodynamic oil film to maintain a gap between the shaft & bearings. They are fed with a continuous supply of lube oil at a high rate to maintain the oil film and remove the heat generated. The shaft imparts high rotational velocities to the oil as it passes through the bearing. Due to high kinetic energy of oil leaving the bearing, gravity drained bearing housings generally have a big sump near the bottom dead center to collect and reduce the kinetic energy of the oil. This facilitates smooth drain of oil back to the oil tank. The use of gravity to facilitate the draining results in a simple and cost-effective bearing system. The size of sump is determined by the oil flow rate in the bearing housing which itself is a function of rotor load, speed & temperature. In absence of this oil sump (in applications where there is little or no room for a large bearing housing) the swirling oil in the bearing housing doesn’t get enough time to slow down. The rapidly swirling oil therefore fails to drain into the drainpipe(s), and eventually floods the housing and leaks out through the shaft seals. The failure to drain can be attributed to multiple reasons like air pressure fluctuation, oil vortex formation, oil frothing, etc. This paper focusses on the design of a journal bearing for gas turbines without an oil sump due to design space restrictions. The flow fields in the bearing are chaotic and difficult to analytically predict without experimental validation. Therefore, a bearing rig was constructed, and multiple tests were conducted to understand the flow characteristics inside the bearing housing. Based on the understanding of the flow characteristics, design modifications were made and validated to enable the design of a sumpless gravity drained bearing housing. This paper discusses the methodology and findings from these rig tests which led to the design solutions that solved the issue of draining the high energy oil back to the oil tank without the need of having a traditional oil sump.

Abstract:
This paper addresses the three-dimensional analysis of unsteady flow in the RWT (Refueling Water Tank) for the prediction of the potential for air ingression into the ECC (Emergency Core Cooling) pump during the SBLOCA (Small Break Loss Of Coolant Accident) at KSNPs (Korean Standard Nuclear Power plants). Upon the receipt of RAS (Recirculation Actuation Signal) by the occurrence of SBLOCA, the RWT outlet valve is designed to be isolated manually. At the nuclear power plants without the provision of automatic isolation operation of the valve on the downstream of the RWT line, the refueling water begins to discharge from the RWT, which may result in forming and developing the vortex flow in the RWT, under the condition of the minimum pressure of containment and minimum water level of containment recirculation sump during the phase of RAS. Due to the vortex flow, when the water level is below the critical height, a dip starts to develop, causing air ingression before the refueling water drains fully. Hence it can be surmised that there is a possibility of ECC pump failure due to air ingression into the ECC supply line even before the RWT is fully drained. Therefore, in this work, when the RAS is actuated followed by the SBLOCA occurrence, a quantitative evaluation for the maximum limiting allowable time for the manual closing of RWT outlet valve is carried out to eliminate the possibility of air ingression into the ECC pump from the RWT. To do this, the unsteady flow field in the RWT including the drain pit with the connected discharge piping in the process of SBLOCA is analyzed using a CFD (Computational Fluid Dynamics) code. In addition, the transient flow behavior accompanying air entrainment resulting from the dip formation due to vortex flow at the upper part of RWT is examined and the applicable limiting time of the isolation valve closing for preventing air ingression is assessed.

Abstract:
Additive technologies able to successfully lubricate gas engines have been available for many years, but in recent years the acceleration of both commercial and technical demands placed on gas engine lubricants has highlighted the performance limits of traditional additive solutions. One of these limits is the ability to reach long and very long oil drains, required by an increasing number of operators. Since traditional additive chemistries on conventional base oil systems have reached their limits in that respect, focus has been increasingly placed on using higher performance base oils so that longer oil drains can be reached. However, traditional additive chemistries have often proved to struggle in these higher performance base oils, particularly in the aspect of deposit control — demonstrating that a new generation of additive systems for the formulation of gas engine oils is needed. The authors present one such generation of additive systems, developed around off-the-beaten-track detergent technology; providing superior control of oxidation and deposits. Such additive systems can be used either in conventional base oil systems with improved drain interval, or in high performance base oil systems with very long drain interval and excellent control of deposits. Besides the description of the chemistry involved, the authors also present a methodology of performance evaluation in the laboratory, and compare this methodology with the performance perceived in the field.

Abstract:
The incorrect design and/or poor location of service connections on steam surface condensers can cause serious, often catastrophic, failures due to the inadequate dispersion of drain fluid energies. These failures often occur during a number of different operational scenarios, which in turn can cause condenser tube and/or structural failures, both of which can lead to the de-rating of steam turbines, or even complete unit shut downs. This paper includes the latest thermal and mechanical design guidelines and general considerations for the proper design, and location, of various types of service connections on steam surface condensers. The paper also includes considerations for a number of special cases; such as steam bypass, deaerating drains, heater drains, etc. Furthermore, examples of common operational issues are included, together with recommended modifications and upgrades to address typical service connection failures on existing condensers. A Case Study and some examples are also referenced.

Full text
Abstract:
This paper represents a case study of a replacement single-zone vertical feedwater heater with a pump forward drains system. When replacing a feedwater heater, it is important to review, evaluate and adjust the NLL of the new heater since it may not be the same as the NLL of the existing heater in order to achieve the same performance, particularly when changing the tube material. This paper strives to explain a method that was used in order to predict changes in both the feedwater and drains outlet temperatures based on varying liquid level. Single-zone feedwater heaters are typically sized and rated with a drains outlet temperature that is equal to the saturation temperature of the incoming bleed steam. Depending on the normal liquid level (NLL) setpoint, there is some subcooling that occurs due to the submerged tube surface that is typically not accounted for in the heater rating, this is especially true in a vertical channel down configuration. The outlet drains of a condensing zone only heater are still required to be safely transported in the liquid state to either another heater or to the condenser, therefore an adequate amount of subcooling is desired in order to preclude flashing and two-phase flow from occurring within the drains piping. The amount of subcooling that can be expected is related to the amount of surface that is submerged and therefore is directly tied to the liquid level inside the heater. Intuitively, more subcooling can be achieved by raising the liquid level; however, this has the effect of reducing the surface area available for condensation and ultimately the feedwater outlet temperature. In a pump forward drains system, this has an additional negative effect in that the drains are then combined with the outlet feedwater and reduces the feedwater temperature further prior to entering the next heater. It was desired to optimize the normal liquid level such that the drains outlet temperature would be subcooled enough to protect the downstream heater drain pump, but not to raise the level to a point that would significantly lower the inlet temperature to the next feedwater heater, resulting in inefficiencies in the overall heat cycle and overloading the downstream heater.

Abstract:
The northern coastal plain of Bering Land Bridge National Preserve (BELA) lost lakes at an alarming rate over the first two decades of this century, including four lakes over 100 ha in size in 2018-2019 alone. To understand the effects of these lake drainages, we sampled vegetation of these lakes in 2019 (a reconnaissance visit) and 2021 (for the installation of permanent vegetation monitoring plots). We used these data to summarize the changes that occurred in the first three years after drainage, and to create vegetation maps from 3-m resolution satellite images coinciding with the visit dates. We used time series of these satellite images to study the rate of drainage and vegetation colonization on the lakes. We analyzed our existing data from older drained lake basins (estimated to be more than 200 years since drainage) and reviewed the literature on vegetation change in drained lakes to understand the vegetation changes that are likely in the future. Finally, we used a model of lake occupancy by loons developed by Mizel et al. (2021) to predict the effect of the 2018-2019 lake drainages on available loon habitat, using both our detailed maps of the four sampled drained lakes, and also data on all drained lakes over most of northern BELA derived from Landsat satellite images. Our results show that the four study lakes drained early in the summer, before the end of June, in 2018 (3 lakes) and 2019 (one lake). A combination of record warm weather and heavy snowfall made 2018 and 2019 especially favorable for lake drainage: thaw subsidence probably enlarged existing drainage outlet channels from the lakes, and large amounts of spring snowmelt runoff deepened the outlet channels by thermal erosion (the combination of thaw and erosion). Drainage exposed moist loamy sediment on the lake bottoms that was rapidly colonized by plants. Substantial vegetation cover developed by late summer in the same year as lake drainage in one lake, in the first post-drainage summer in a second lake, and during the 2nd year after drainage in the remaining two lakes. The first vegetation communities to develop consisted of just one or two dominant species, notably Eleocharis acicularis (spike rush), Equisetum arvense (horsetail), and/or Tephroseris palustris (mastodon flower). Other important early species were Arctophila fulva (pendant grass) and Rorippa palustris (yellow cress). By year 3, the communities had become more diverse, with significant cover by taller wetland graminoid species, including A. fulva, Eriophorum scheuchzeri, and Carex aquatilis. Frozen soil was observed in most locations on the lakes in July of 2021, suggesting that permafrost was forming on the lake bottoms. Comparison of the three-year trends in vegetation change with data from older lake basins suggest that ultimately most lake basins will develop wet tundra communities dominated by Carex aquatilis and mosses, with various low shrub species on acid, peat-dominated soils and permafrost; however, this process should take several centuries. The loon habitat model suggests that drainage essentially eliminated the potential habitat for Yellow-billed Loons on the four study lakes, because the residuals ponds were too small for Yellow-billed Loons to take flight from. A total of 17 lakes drained in northern BELA in 2018-2019. As a result, the potential Yellow-billed Loon nesting habitat in northern BELA probably decreased by approximately 2%, while habitat for Pacific Loons decreased less, by about 0.6%. Habitat for the more abundant Red-throated Loons probably increased slightly as a result of lake drainage, because of their ability to use the small residual ponds created by lake drainage.

Abstract:
Objective: To describe the experience of a multimodal therapeutic approach in a patient with methadone-induced dilated cardiomyopathy who developed recurrent bilateral tension pneumothorax. Setting: Department of Intensive Care. Patient: A patient with methadone-induced cardiomyopathy and severe left ventricular dysfunction who after mechanical ventilation underwent bilateral tension pneumothorax and prolonged cardiovascular resuscitation (CPR). Interventions: Cardiac Angiography, Multiple counter–shock (defibrillator dose), Multiple Thoracic Drains. Case Report: A 56-year-old man with past IV drug abuse and severe left ventricular dysfunction was transferred from the intensive cardiac care unit (ICCU) to our intensive care unit (ICU) ward due to suspected aspiration pneumonia. Multiple attempts of weaning off mechanical ventilation were unsuccessful, followed by development of septic shock. Following cardiothoracic consultation, two thoracic drains were placed. Due to repeated events of bilateral tension pneumothorax and CPR attempts, a total of seven thoracic drains were placed, permitting rapid control and improvement in the patient status. The possibility of Extracorporeal Membrane Oxygenation (ECMO) was not considered as supportive care due to methadone use and severe secondary cardiomyopathy. In the following days, control and stabilization of the patient status was obtained. Vasopressor treatment withdrawal, cessation of drainage and removal of five thoracic access points were successfully performed prior to percutaneous tracheostomy. The two remaining drains were removed later on during hospitalization. After 29 days in the ICU, the patient was discharged to a step down ward.
