Study on mechanical properties of high-strength casing milling and mechanisms of high-efficiency windowing drill bit

During breaking window in deep and ultra-deep wells, the cutting teeth of the drill bit are prone to be blunted due to the thickness and high strength of the casing wall and the poor drillability of the rock. A new milling cone bit is innovatively designed. The bit has 9 cutter wings, and double rows of cutting teeth are staggered on each cutter wings to enhance the ability and stability of window breaking. The dynamics simulation model of sidetracking window was established to explore the law of window formation and verify the feasibility of the design of the drill bit and its whipstock. Drill bits and supporting tool structures are optimized with the aid of simulation. The prototypes of drill bit and whipstock were developed to carry out the windowing test of TP155V steel casing (yield strength up to 1068 MPa). It was revealed that the success rate of windowing is 100%. The similarity between the window shape obtained by the experiment and the window shape obtained by simulation is nearly 100%. The bit and its tools provide a new method of casing windowing in deep and ultra-deep wells. Its lays the foundation for further research on the sidetracking process.

The Harlem Uprising: Segregation and Inequality in Postwar New York City

Christopher Hayes shows in his aptly titled The Harlem Uprising that the unrest that swept through central Harlem and Brooklyn's Bedford-Stuyvesant neighborhood during July 1964 emerged from a longer history of racial segregation, economic transformation, and political marginalization. The first five chapters detail the “vast system of structural discrimination” that became worse, not better, during the heyday of civil rights activism (p. 2). Duly attentive to the seemingly impersonal forces that bounded the promise of postwar prosperity, Hayes repeatedly and rightly emphasizes the role of policy choices and political calculation in stymying Black New Yorkers' efforts to secure access to housing, jobs, unions, schools, and policing. That confluence of “rising expectations” and “declining fortunes” was central to the six days of demonstrations that followed the July 16, 1964, shooting of fifteen-year-old James Powell (p. 5). In the book's most original contribution, the middle six chapters examine the response of a Black community that had already become rapidly disillusioned with nonviolence and racial integration. Reconstructing the week's developments in remarkable detail, Hayes recounts days filled with meetings between civil rights leaders who had little local credibility and city officials who had little desire to address the deeper roots of the crisis. While movement veterans such as James Farmer and Bayard Rustin pleaded for peace each evening, a growing number of Black Harlemites and Brooklynites turned to bottle throwing, window breaking, and store looting to protest both systematic abuses by the New York Police Department and a much broader range of grievances. After six days, the protests petered out and a superficial calm returned, but never again would Black New York invest the same faith in liberal politics.

499 What light through yonder window breaks? Benefits of optical coherence tomography (OCT) in a case of spontaneous coronary artery dissection

Abstract Aims Spontaneous coronary artery dissection (SCAD) is a non-traumatic and non-iatrogenic separation of the coronary arterial walls, creating a false lumen. SCAD is an infrequent and often missed diagnosis especially in women presenting with acute coronary syndrome and in the majority of cases angiography alone could be insufficient for identification. Methods and results A 43-year-old woman presented to the Emergency Department of Fondazione Policlinico Universitario A. Gemelli IRCCS (Rome, Italy) for oppressive acute chest pain radiated to the right jaw, resolved spontaneously within a few minutes. Physical examination, including cardiovascular evaluation, was normal. High-sensitivity troponin was 152 ng/l and 250 ng/l in two serial determination (reference range, 0.0–37 ng/l). EKG showed sinus rhythm with no significant ST-segment alterations. Echocardiography revealed preserved biventricular systolic function with mild hypokinesia of the apical segments of the left ventricle. A diagnosis of NSTEMI was made based on clinical and laboratory parameters. Thus, urgent coronary angiography was performed, which demonstrated a single vessel disease with an eccentric, and angiographically complex stenosis of the proximal left anterior descending (LAD) artery with an image of plus compatible with a plaque ulceration. In order to define the extension of the disease and ostium involvement for a better procedural planning, OCT imaging was performed. Surprisingly, OCT showed a intramural haematoma extending from the ADA ostium to the proximal tract (approximately 22 mm) with ulceration in the body, minimal lumen area (MLA) 2.0 mm2 and evidence of normal trilaminar structure of the vessel both on downstream and upstream of the lesion. The angiographic features were compatible with type 2A SCAD. The therapeutic management was conservative with continuation of the double antiplatelet therapy and remote CT monitoring. Three days later, because of a new onset of chest pain and slight elevation of the ST segment on EKG, was performed a coronarographic control: the angiographic appearance of the lesion was substantially unchanged; OCT showed unmodified longitudinal extension of the lesion (about 22 mm) and relative increase in the endoluminal caliber compared to the previous examination (MLA 4.0 mm2).After 2 weeks, coronary CTA control was carried out, which documented the stability of the intramural hematoma in the proximal LAD, extended for 22 mm and with a maximum thickness of 2 mm, determining lumen narrowing of 40–45% The patient was discharged on medical therapy and no events occurred during the follow-up. Six month later, repeat CTA showed a complete resorption of the intramural haematoma. Conclusions In this case we highlight the utility of intravascular imaging, in particular OCT, in the evaluation of angiographic lesions of non-univocal interpretation and how its use can change the management and prognosis of ACS patients. Furthermore, the spontaneous resolution of the clinical and anatomical scenario through conservative treatment additionally confirms spontaneous healing as the natural history of SCAD and foreground the role of precise diagnosis (and intravascular imaging showed to improve it) for therapy shift and calibration.

Experimental Study of the Effect of Confining on the Development of Fire in a Closed Compartment

Backdraft is a complex phenomenon which occurs during cases of confined fires. It appears by a fast deflagration which occurs after the introduction of oxygen into a compartment filled with hot gases rich in unburned combustible vapor. Practically, this situation could occur at the time of intervention of firemen who break the door or when a window breaks under the action of thermal stresses. Based on a strong experimental campaign, the present paper aimed to make a quantitative investigation of the effect of confining on a totally closed fire. With this focus, fire tests were carried out in a completely closed room of dimensions 1.20 m × 1.20 m × 1.02 m, with five sources of fire of different heat release rates. The same fire sources were also tested in a free atmosphere in order to get reference data. After a statistical study of data, a comparative analysis between both results has been done. Its outcome is that confining has a major impact on the quality of combustion and on the fire duration. More precisely, it has been noticed comparatively to fire tests in free atmosphere that confining increases the fire duration by 14.85 percent while it decreases the heat release rate by 21.72 percent.

Optimizing the Egress Route Using a New Smoke Emulator IoT System

The ability to find optimal egress routing is critical for safe and effective firefighting processes. This article presents a novel smoke emulator that can be used to provide this ability in firefighting processes. It has two fundamental components: 1) a sensor network based on the Internet of Things (IoT) and 2) a simplified computational fluid dynamics (CFD) smoke simulator based on Navier-Stokes equations. Supported by IoT, real-time events, such as door opening and window breaking, can be detected, and the relevant information can be used to update the variables in CFD to ensure high accuracy and relevancy. A long short-term memory (LSTM) is employed to evaluate the values of any sensors temporarily malfunctioning. A two-level of A* routing algorithm (Nosrati et al., 2012) has also been developed to optimize the egress routing for evacuees with an aim to minimize the time of smoke exposure. Simulation studies demonstrated that this smoke emulator helps significantly improve the firefighting process's safety and effectiveness.

Analysis and design of emergency field isolation hospital building using innovative rapidly construction prefabricated units to treat patients infected with COVID-19

Coronavirus pandemic is the most catastrophic phenomena of nature. In a major disaster which affected substantially to human lifecycle and property loss. Instant rehabilitation for the people affected with coronavirus was essential. As an immediate measure, it led to the application of light-gauge steel within Saudi Arabia for quick construction, in addition for the safety purposes during disaster in the forthcoming. Several hospital buildings with changeable categories of earthquake and seismic performance design needs are present. Broadly, the earthquake performance is categorized into two types: structural and non-structural, either under unsatisfactory conditions can be dangerous to occupants in the building once damage occurs. The deprivation in structural support of hospital building’s systems (i.e. lateral and vertical force resisting systems) like frames and walls in the hospital building comes under structural damage, whereas the non-structural damage means the damage which doesn’t affect the structural support system reliability such as pipes damage and pumps disruption, window breaking, breakdown of chimney viz. Furthermore, the non-structural damage is life intimidating also uneconomical.

Searching for a Soul Mate

Philadelphia: University of Pennsylvania Press, 2019. 224 pp. Bibliography and index $49.95 Carol Faulkner, Unfaithful: Love, Adultery, and Marriage Reform in Nineteenth-Century America. Philadelphia: University of Pennsylvania Press, 2019. 224 pp. Bibliography and index $49.95 The prize for the most famous metaphor in literature goes to Shakespeare, either for "All the world's a stage" or "But soft! What light through window breaks? It is the East, and Juliet is the sun." The world is decidedly not a stage and Juliet was a teenage female character in a play (that was on a stage), not a centrally placed star consisting of blazing hot gasses. But the mind delights in finding correspondences between wildly different things. Metaphors comparing marriage to something else are centuries old because the wedded state is known by all and significant almost everywhere. Marriage could be the caboose or the engine of comparison. The marriage could be the unqualifiedly favorable term, as in postrevolutionary America where the bonds of citizens to the new republic were likened to the lifelong and affectionate ties of husband to wife. Or marriage could be the clearly unassailable term, as for defenders of slavery, who argued that the peculiar institution resembled marriage since both were based on "natural hierarchy." Since the seventeenth century, intellectuals and reformers have employed the metaphor of marriage as a form of slavery to critique the unequal, even unsavory aspects of marriage. Madeleine de Scudery, the French saloniste and novelist, originated the metaphor. She had in mind ancient bondage, not transatlantic slavery, and was especially animated by the unfreedom of arranged marriage. The English advocate of woman's rights Mary Astell picked up the metaphor about a half century later because she believed that in marriage the wife was subjected to the arbitrary will of her husband, a condition she thought morally wrong. Later on, U.S. abolitionists and "feministabolitionists" (the term of Blanche Glassman Hersh) amplified and made more concrete the marriage metaphor, naming runaway wives as "fugitive slaves." Utopian socialists in the early nineteenth century originated the comparison of marriage with prostitution, not quite as popular as the slavery metaphor, and communitarians and advocates of woman's rights followed their lead.1 A third metaphor—that marriage was a form of adultery—seems counterintuitive [End Page 569] and was considerably less popular, although it was often employed by the same reformers who used the slavery and prostitution metaphors. It, too, originated with European intellectuals; it surfaced in the American press when sex radicals in the U.S. in the 1850s began to refer to the unwholesome nature of sex within a loveless marriage. Historians have noted but not paid much attention to the use of the adultery metaphor because it was less commonly employed than the other two and because historians, like most nineteenthcentury Americans, dismissed those making use of it as cranks. Carol Faulkner, more respectful and appreciative of such rhetoric and the mavericks who employed it, traces the use of the adultery metaphor among critics of marriage between the 1830s and 1880. Her geographic focus is New York state—the newspaper capital of the nation, the home of many spiritualists and of several of the most important intentional communities whose members practiced their own version of freedom within and from marriage. Her cast of characters includes familiar figures—for example, John Humphrey Noyes and Victoria Woodhull—and some colorful unknowns she learned about from the records of communes, newspapers, published memoirs, and personal papers. The lesser-knowns and unknowns are a fairly heterogeneous group of white Anglo-Saxon men and women, some of whom were legally married couples. With the exception of Paschal Bradley Randolph, a biracial spiritualist who sometimes identified himself as Indian, sometimes as Black, the group is entirely white. Randolph, who was decidedly more on the moderate side of the movement, confronted the racism of one of his fellow reformers several times. The one member of the working class was Marie Howland, a former Lowell mill girl whose novel, Papa's Own Girl (1874), expressed her twinned...

Study on the influence of the number of broken windows on the fire of running trains

With the rapid development of Railway Construction in China, the safety of railway trains has aroused people’s concern while solving the traffic problems of passenger flow in various cities. According to the principle of relative motion, this experiment studies the fire burning characteristics of trains at different travel speeds by changing the wind turbine frequency to adjust the wind speed. The experimental results show that when the train window breaks during travel, the fire heat release rate increases with the increase of running speed. The growth coefficient of fire increases with the increase of running speed. With the increase of train running speed, the variation of the temperature extremes of the ceiling and the temperature series on both sides of the fire source is not very large.

Full-Scale Fire Test of an Intercity Train Car

Fire development inside a train car is a topic that has not been studied extensively due to the complexity of the problem and the need for a real train car and the appropriate facilities to conduct these tests in a controlled environment. This paper presents detailed experimental data on fire development inside a real intercity train car. The facility used for the tests is capable of conducting such large-scale fires and measuring the heat release rate using oxygen consumption calorimetry. Thermocouples and plate thermometers were installed inside the train car to provide an insight of the fire development. A number of cameras were also placed inside the car and in the tunnel providing live videos during the test. The peak heat release rate was 32 MW at 1081 s after ignition, and the fire burned 83% of the initial fire load. Flame spread data and recordings of window breaking events are discussed and compared to the heat release rate data. A local flashover-type phenomenon where the fire involved all combustibles at the rear of the car was found to occur.

The home range of a recently established group of Southern ground-hornbill (<i>Bucorvus leadbeateri</i>) in the Limpopo Valley, South Africa

Little is known about Southern ground-hornbill (SGH) population ecology outside of large, formally protected areas where the largest declines in numbers have been recorded. The SGH has started re-colonising, establishing group territories and breeding successfully in the Limpopo Valley on the northern border of South Africa, following localised extinction from the 1950s to the 1970s. A group of SGH was monitored over a period of 14 months by means of radio telemetry across privately owned land in order to investigate their seasonal habitat movements in this semi-arid, predominantly livestock-based environment. We also investigated seasonal fluctuations in invertebrate prevalence, as an indication of food availability and its influence on seasonal SGH group movements and foraging activity patterns. There was a clear increase in food availability during the summer rainfall period allowing the group to forage over a wider area, whilst winter foraging remained localised within their range. Kernel home range analysis indicated a marked difference in size between the summer (13 409 ha) and winter (5280 ha) home ranges, with an overall home range of 19 372 ha, which is approximately double that of home ranges recorded that fall within formally and informally protected reserves. In this article, we proposed that food availability is the driving force for home range size and seasonal activity patterns in a semi-arid livestock-ranching habitat.Conservation implications: The Limpopo Valley SGH population is one of the most significant outside protected areas in South Africa. This population is especially vulnerable to threats such as poisoning, persecution for window breaking and drought, as shown by their near extirpation from the area. Conservation efforts need to focus on awareness amongst local farmers, provision of artificial nests and continued monitoring of groups.

Monkey & Elephant’s Worst Fight Ever by M. Townsend

Townsend, Michael. Monkey & Elephant’s Worst Fight Ever. New York: Alfred A. Knopf, 2011. Print. Best friends Monkey and Elephant live on a tiny island with many other animal inhabitants. One night, Monkey decides to bring Elephant a surprise gift–a tray of delicious cupcakes. Much to his dismay, Monkey spies what he believes to be a costume party going on at Elephant’s house – to which he was not invited! Feeling very sad, Monkey runs away, all the while reminiscing about the good times he and Elephant have had, which leaves him feeling confused about why Elephant would leave him out of the party plans. Sad, however, quickly turns to mad and the desire to get even, and Monkey freezes Elephant’s toys into blocks of ice. Elephant is shocked by his best friend’s actions. Why, they collected pet rocks and watched pro wrestling together! In turn, he too gets mad and retaliates. The back-and-forth havoc escalates until the islanders decide that enough is enough and plan an intervention for the former best friends. While Monkey and Elephant are sleeping, they are set adrift in a small boat and are ordered not to return to the island until they have hugged and made up. The two friends bicker, but eventually the truth comes out– Elephant’s party was actually going to be a surprise wrestling match for Monkey. An embarrassed Monkey admits he should have asked about the party, and both friends apologize for their rude behaviour. Upon their return, the islanders rejoice, and everyone enjoys the wrestling match.

Fans of graphic novels will enjoy the comic book feel to this book, though children younger than the publisher-recommended age range of 5-8 may find the storyline distracting. Somewhat questionable, however, are the friends’ over-the-top antics, which lead to violence, including the breaking of windows. However, the “don’t jump to conclusions” plotline will inspire bedtime conversations, and the contemporary and colourful drawings are funny and engaging.

The Exclusion Problem Meets the Problem of Many Causes

In this paper I develop a novel response to the exclusion problem. I argue that the nature of the events in the causally complete physical domain raises the “problem of many causes”: there will typically be countless simultaneous low-level physical events in that domain that are causally sufficient for any given high-level physical event (like a window breaking or an arm raising). This shows that even reductive physicalists must admit that the version of the exclusion principle used to pose the exclusion problem against non-reductive physicalism is too strong. The burden is on proponents of the exclusion problem to provide a reason to think that any qualifications placed on the exclusion principle will solve the problem of many causes while ruling out causation by irreducible mental events.

A Different Approach to Vent Flow Calculations in Fire Compartments using the Critical Flow Condition

In enclosure fires, density-driven vent flow through an opening to the fire compartment is directly dependent on the state of the fire and the evacuation of smoke and hot gases. If a fire is strongly under-ventilated, there may be heavy production of flammable gases. If a sudden opening occurs, e.g., a window breaks or a fireman opens a door to the fire compartment, fresh air enters the compartment and mixes with hot gases, thus creating a flammable mixture that might ignite and create a backdraft. In this article, we consider the critical flow approach to solve the classical hydraulic equations of density-driven flows in order to determine the gravity controlled inflow in a shipping container full of hot unburnt gases. One-third of the container’s height is covered by the horizontal opening. For the initial condition, i.e., just before opening the hatch, zero velocity is prescribed everywhere. When the hatch is opened, the incoming air flows down to the container floor and the hot gas flows out. The interface in between them (the neutral plane) can move up like a free surface in internal flows, making it possible to use the techniques of open channel hydraulics devised by Pedersen [1]. In this article the critical flow condition, known from classical hydraulics, is used providing a new equation for the vent flow problem. Two flow correction coefficients are considered at the opening, taking into account the uneven distribution of velocity (α) and the effect of mixing and entrainment (C). The value of these coefficients is evaluated using computational fluid dynamics simulations and physical model results performed for the same geometry. Together, these two coefficients form the flow correction coefficient used in practical formulas for vent flow in fire protection engineering. These are known to have a little different values for different geometries and flow situations. The resulting flow coefficient varies slowly with the density difference, shows a small variation with geometry and compares well with previously published data.

The aftermath of 9/11. What light through yonder window breaks? [free-space laser link

The local communication infrastructure was hit hard by the events of September 11. Financial corporations with an urgent need to transmit high-speed data between offices in physically separate locations were particularly affected, and scrambled to come up with viable alternatives to disrupted fiber-optic cables and RF-based wireless networks. According to a report in Conformity (December, 2001), Merrill Lynch turned to free-space optics for setting up a communication link between its office in lower Manhattan and backup offices across the river in Jersey City, New Jersey. The data were transmitted across the 1.6-mile distance via a laser beam. While free-space optics has been around for over thirty years, and has been investigated for many exotic applications such as satellite-to-satellite communication, it has not been used widely in mainstream applications. Merrill Lynch opted for a free-space laser link because such a system could be up and running within a few hours, following a disaster such as the WTC collapse.

Rehab rounds: Behavioral management of aggression through teaching interpersonal skills.

Introduction by the column editors: Aggressive behavior is a major problem among mentally ill people—in the community as well as in institutions. Epidemiologic data indicate that aggressive behavior occurs more often among individuals with psychotic disorders, especially when they have persecutory delusions and hallucinations or a comorbid substance use disorder (1). Aggressive individuals, with their high frequency of unpredictable verbal threats, throwing of objects, breaking of furniture and windows, and physical assaults, tend to populate long-term units in psychiatric hospitals disproportionately (2). Psychotropic medications rarely ameliorate these behaviors, and even when they are able to suppress aggression, they often result in unacceptable side effects, including "chemical restraint." Physical seclusion and restraint are often used but have never been shown to yield benefits beyond temporary control.The treatment of choice for aggressive and destructive behavior is applied behavior analysis and therapy (3), including interventions that can teach patients alternatives to aggression and reduce the likelihood of future aggression (4). Social skills training has been shown to be effective in building behavioral repertoires that enable individuals to have their social and material needs met in appropriate ways (5), rather than through creating disturbances. A spectrum of positively reinforcing methods, including differential reinforcement of other behavior, differential reinforcement of incompatible behavior, use of environmental antecedents to change the patient's affect, and use of the token economy, have been empirically validated as treatment interventions to reduce or eliminate aggression (6,7,8).To contain and manage aggressive and destructive behavior, special inpatient units have been established where behavior therapy procedures can be implemented effectively and competently by interdisciplinary staff, usually supervised by a behaviorally trained psychologist. This month's Rehab Rounds column describes a unit at Arizona State Hospital that employs a multimodal array of interventions—especially social skills training—to modify aggression and build adaptive repertoires.
