Abstract With the far-reaching reservoir target coupled with other surface constraint including fix well slot coordinate and pre-determined conductor size, the longest well with 2.5 ERD Index in Offshore East Java was pioneered. The team has big task in hand to ensure all aspect of ERD well engineering and construction are being addressed properly within the fast-paced time frame given. One of the approaches strategized by the team is to split the high angle big hole size long interval of middle section into two casing string which was not the common architecture applied in the other offset wells. The objective was to ensure that the middle section of the well will not be compromised and avoid complication in the deeper section of the well. Worth to mention that the middle section consists combination of challenging lithology that deserve the right solution to avoid unwanted problem. There are highly kartsitified carbonate formation, shale and sand interbedded formation, and thick time dependent shale formation. To mitigate the challenges previously mentioned, intermediate section which is normally drilled and isolated with 17-1/2" hole × 13-3/8" casing in previous wells, now separated into two sections which require enlargement: 17-1/2" to 20" and 14-3/4" to 17-1/2". This paper focuses on 14-3/4" × 17-1/2" which is the most challenging underreaming operation in this well and the first of its kind in this field application. Adding to the fact that the inclination reach 75 degree in this section, SOBM and RSS BHA are deployed to mitigate the torque and drag issue. State of the art modelling tool is also used by team to define effectively match BHA and drilling parameter with minimal lateral vibration and stick slip for this section Apart from drilling stage, the enlarged hole size requires a condition to have uncommon casing size and specification, 16" intermediate semi flush liner connection and 13-3/8" full flush intermediate casing connection to ensure sufficient annular area and less restriction during running to bottom. The relentless effort to secure one the most critical ERD well construction phase has really paid off by allowing the next phase of operation to be executed as per plan thus assuring the overall well objective is met.

Chapter 8 focuses on threats to construct validity arising from the left-hand side time series and the right-hand side intervention model. Construct validity is limited to questions of whether an observed effect can be generalized to alternative cause and effect measures. The “talking out” self-injurious behavior time series, shown in Chapter 5, are examples of primary data. Researchers often have no choice but to use secondary data that were collected by third parties for purposes unrelated to any hypothesis test. Even in those less-than-ideal instances, however, an optimal time series can be constructed by limiting the time frame and otherwise paying attention to regime changes. Threats to construct validity that arise from the right-hand side intervention model, such as fuzzy or unclear onset and responses, are controlled by paying close attention to the underlying theory. Even a minimal theory should specify the onset and duration of an impact.

AbstractIn severe cases of COVID-19, late complications such as coagulopathy and organ injury are increasingly described. In milder cases of the disease, the exact time frame and causal path of late-onset complications have not yet been determined. Although direct and indirect renal injury by SARS-CoV-2 has been confirmed, hemorrhagic renal infection or coagulative problems in the urinary tract have not yet been described. This case report describes a 35-year-old female without relevant medical history who, five days after having recovered from infection with SARS-CoV-2, had an unusual course of acute pyelonephritis of the right kidney and persistent fever under targeted antibiotic treatment. A hemorrhagic ureteral obstruction and severe swollen renal parenchyma preceded the onset of fever and was related to the developing pyelonephritis. Sudden thrombotic venous occlusion in the right eye appeared during admission. Symmetrical paresthesia in the limbs in combination with severe lower back pain and gastro-intestinal complaints also occurred and remained unexplained despite thorough investigation. We present the unusual combination of culture-confirmed bacterial hemorrhagic pyelonephritis with a blood clot in the proximal right ureter, complicated by retinal vein thrombosis, in a patient who had recovered from SARS-CoV-2-infection five days before presentation. The case is suspect of a COVID-19-related etiology.

The Act on the Protection of the Right to a Trial within a Reasonable Time, which took effect in 2016, has created the conditions in our legal system for the protection of the right to a trial within a reasonable time, as one of the fundamental rights guaranteed by the Constitution of the Republic of Serbia and related international documents. Although the legislator does not explicitly provide for the application of this Act in the context of bankruptcy proceedings, it has been used in judicial practice as a mean for the bankruptcy creditors to obtain just satisfaction in cases involving lengthy bankruptcy proceedings and a violation of the right to a fair trial within a reasonable time. The subject matter of analysis in this paper is the right to a trial within a reasonable time in bankruptcy cases. For that purpose, the authors examine the case law of the Commercial Court in Niš in the period from the beginning of 2016 to the end of 2019, particularly focusing on the bankruptcy cases in which complaints (objections) were filed for the protection of the right to a fair trial within a reasonable time. The aim of the research is to examine whether the objection, as an initial act, is a suitable instrument for increasing the efficiency of the bankruptcy proceeding, or whether it only serves to satisfy the interests of creditors. The authors have also examined whether this remedy affects the overall costs and duration of the bankruptcy proceeding. The main finding is that there is an increasing number of objections in the Commercial Court in Niš, which still does not affect the length and costs of bankruptcy. This trend is not only the result of inactivity of the court and the complexity of certain cases but also of numerous external factors, the most prominent of which is the work of some state bodies.

<p>In this paper we aim to add additional knowledge regarding the occurrence, origin and epidemiological features of the English sweating sickness. The English sweating sickness raged in five devastating epidemics with mortality rates between 30 and 50% between 1485 and 1551 throughout England, and on one occasion also affected mainland Europe, in 1529. The Picardy sweat, generally considered as the English sweating sickness’ lesser deadly successor, flared up in France in 1718 and caused 196 localized outbreaks with varying severity all over France and neighboring countries up to 1861. The English sweating sickness has been the subject of numerous attempts to define its origin, but so far all efforts have failed due to lack of material, DNA or RNA, that - using modern techniques and knowledge - could shed light on its cause. Although the time frame in which the English sweating sickness occurred and the geographical spread of the outbreaks is generally known, we will demonstrate here that there was more to it than meets the eye. We found reports of cases of sweating sickness in years before, after and between the 1485, 1508, 1517, 1529 and 1551 epidemics, as well as reports of sweating sickness in Italy and Spain.</p><p><strong>Conclusion. </strong>In spite of the fact that the English sweating sickness apparently has not caused casualties for a more than a century now, we suggest that -given the right circumstances- the possibility of re-emergence might still exist. The fact that up until today we have no indication concerning the causal pathogen of the English sweating sickness is certainly not re-assuring.</p>

Introduction: Ischemic stroke patients who arrive by emergency medical service (EMS) receive faster emergency department evaluations and improved rates of thrombolytic treatment. However, EMS stroke recognition and compliance with prehospital stroke quality measures are inconsistent. We hypothesized that EMS stroke care is influenced by a complex interaction of knowledge, beliefs, and system-level variables that influence behavior. Methods: Focus groups of paramedics from a single urban/suburban county were assembled to discuss their experiences identifying and transporting stroke patients. Focus groups were conducted using a semi-structured interview format and audio recorded. Transcripts of focus groups were qualitatively analyzed to identify themes, subthemes, and patterns of paramedic responses. The Clinical Practice Guidelines Framework provided the initial coding scheme, which was modified during the coding process by three coders using grounded theory methods, who came to consensus on which codes to apply. Results: Three focus groups (n=13) were conducted to reach theme saturation. Overall, paramedics reported high confidence in clinical gestalt for assessing stroke patients and a strong desire to “do the right thing,” but were unfamiliar with published guidelines. Paramedics identified variability in the clinical presentations of stroke, inadequate or inconsistent hospital guidance, and lack of feedback regarding care as principle barriers to ideal prehospital stroke care. Participants reported conflicting hospital guidance regarding the appropriate time frame for a high priority transport and hospital prenotification. Feedback regarding final diagnosis was viewed as critical for developing improved clinical acumen. Direct to CT protocols were cited as an effective way to integrate EMS into hospital stroke response. Conclusion: In this qualitative analysis, paramedics expressed a desire for clear, hospital-directed guidance and consistent feedback regarding outcomes for suspected stroke patients.

Cyber Ethics

The central problem in cyber ethics is not, as many might think, how to address the problems of protecting individual privacy, or preventing software piracy, or forcing computer programmers to take responsibility for the systems that they build. These are, of course, legitimate concerns of cyber ethics, but the central problem is how you decide what the right thing to do is with regard to these issues when the consequences of any responses cannot be known in advance. Stated more clearly, the central problem in cyber ethics is - how do you establish ethical standards in a professional field that is defined by a rapidly evolving technology where the consequences of the technology and the impact of any ethical standards cannot be known in the time frame in which the standards must be established? Stories play a very important role in addressing this issue. Specifically, stories provide a means of exploring ethical issues for which the full range of consequences is not currently known. But, in order to justify this claim, a few words of explanation are in order.

AbstractIntroduction:Intracranial complications are recognised as rare, but serious, sequelae of endoscopic sinus surgery.Case report:A 56-year-old woman was referred after developing meningitis following elective functional endoscopic sinus surgery. Computed tomography demonstrated a significant defect of the skull base in the right posterior ethmoid, clearly visible on both coronal and sagittal sections. Operative exploration demonstrated the skull base to be intact in the posterior ethmoid area identified on the scan, and the overlying mucosa appeared undisturbed. Scans were reviewed in the light of operative findings; coronal and sagittal images were found to be reconstructions. Directly acquired coronal computed tomography, undertaken three weeks after surgery, demonstrated a complete bony plate in the right posterior ethmoid at the site previously identified as dehiscent.Discussion and conclusion:We speculate that the posterior ethmoid defect was actually an artefact of reconstruction. We cannot exclude the alternative possibility of remineralisation, but given the time frame this seems unlikely. This case highlights the need for caution when interpreting reconstructed images of the thin bony plates of the skull base and lamina papyracea, as regards both clinical significance and medicolegal reporting. While virtual defects have been reported in the superior semicircular canals as a result of reconstructed images, we believe this to be the first reported case demonstrating a similar problem in the anterior skull base.

This paper addresses the experiences and challenges of Hungary’s monetary policy during the period 1995–2000 and in view of the progress toward EU and EMU membership. The structure of relative prices changed markedly in the past and is expected to continue to change in the future. The reason, in addition to a possible Balassa–Samuelson effect, was the elimination of subsidies and introduction of turnover taxes in the past, and a future convergence toward a price structure prevalent in the EU. In the 1995–2000 period, the resulting gap between CPI and PPI led to massive foreign capital inflows. While the policy of sterilised interventions by the National Bank of Hungary was probably the right answer, it was inevitably costly, and was made costlier than necessary by the way it was carried out. Continued adjustments in the price structure in the future will confront monetary policy with the same dilemmas and, resulting in an inflation floor, will complicate the country’s conditions of joining EMU within a reasonable time frame after EU accession.

From the vantage point of mid-1970s, the author looks back a hundred years, to see the global social change that occurred during this period in perspective, and then forward a hundred years, to be able to foresee where the global order may be heading. By choosing this particular vantage point, she emphasizes the transitional nature of the 1970s, when the seed is being sown but the sprout is yet to show up. And by choosing a 200-year time-frame, she recognizes that a period of less than 100 years is apt to distort the view of the past with one's prejudices as it is apt to colour the view of the future with one's wishes. Arising from the experience of colonialism and decolonization syndrome, both North and South have entered a phase of prolonged crisis that may as well help as hinder both in meeting it with the right response. There are, however, signs that a process of what is at once learning and teaching is under way - in other words, a dialogue as between equals - which, when brought to fructification, may indeed usher in a new global order. The author takes a hundred-year leap forward for a look-see of the world as it might be in the year 2075.

Every manufacturing system can only survive with a high level of system planning and budgeting. Production planning is a sequential ladder in the manufacturing setting to ensure that materials input (raw materials, men, money, and machine) is made available within a stipulated time frame, in the appropriate amount to produce the demanded output of goods and services based on the schedule specified. Production planning also helps in making available high quality of goods and services in the right quantities to the customer at the demanded delivery timing to attain higher degree of customer satisfaction. Through production planning, different departmental activities i.e., engineering, production, purchasing, sales, and marketing, as well as stock control department, and other units that may relate to production are coordinated to attain a regular, steady, and balanced flow of production thus, enhancing reduction in production cycle time. Production planning serves as an instrument which estimates to gear up the performance of different departments and individuals of an organization in such a manner that will enhance better service to customers, fewer rush orders, more efficient use of equipment, reduced idle time of both machine and personnel, improved plant morale, good public image, and lower capital requirement, it may also create alternative plans to meet any form of emergency or contingency during the cause of production. From the foregoing, a manufacturing system that incorporates production planning in its operations will be more efficient, effective, and economical as compared with those that did not.
