Over the last few years, attendance rates in remote schools have fallen, and Year 12 completions have also dropped. We are not sure why this is, though events like COVID-19, floods and other natural disasters have not made it easy. The case study presented here was part of a bigger project that sought to understand what people in remote schools and the communities they are in think makes a difference to attendance and Year 12 completion. This case study outlines the findings specific to one of the four case study sites, namely, Yipirinya School on Arrernte Country in Mparntwe (Alice Springs). The overarching finding of the study indicates that attendance alone cannot be the primary measure of school success; rather, engagement needs to be the focus. To tease out this finding, the three main themes: relationships, purpose, and cultural safety, are identified as factors that made a difference at Yipirinya School.

"Long-Term Adherence to a Mediterranean Diet 1-Year after Completion of the MedLey Study." Nutrients 14, no. 15 (July 28, 2022): 3098. http://dx.doi.org/10.3390/nu14153098.

Mediterranean populations enjoy the health benefits of a Mediterranean diet (MedDiet), but is it feasible to implement such a pattern beyond the Mediterranean region? The MedLey trial, a 6-month MedDiet intervention vs habitual diet in older Australians, demonstrated that the participants could maintain high adherence to a MedDiet for 6 months. The MedDiet resulted in improved systolic blood pressure (BP), endothelial dilatation, oxidative stress, and plasma triglycerides in comparison with the habitual diet. We sought to determine if 12 months after finishing the MedLey study, the participants maintained their adherence to the MedDiet principles and whether the reduction in the cardiovascular disease (CVD) risk factors that were seen in the trial were sustained. Participants completed a food frequency questionnaire, and a 15-point MedDiet adherence score (MDAS; greater score = greater adherence) was calculated. Home BP was measured over 6 days, BMI was assessed, and fasting plasma triglycerides were measured. The data were analysed using intention-to-treat linear mixed effects models with a group × time interaction term, comparing data at baseline, 2, 4, and 18 months (12 months post-trial). At 18 months (12 months after finishing the MedLey study), the MedDiet group had a MDAS of 7.9 ± 0.3, compared to 9.6 ± 0.2 at 4 months (p < 0.0001), and 6.7 ± 0.2 (p < 0.0001), at baseline. The MDAS in the HabDiet group remained unchanged over the 18-month period (18 months 6.9 ± 0.3, 4 months 6.9 ± 0.2, baseline 6.7 ± 0.2). In the MedDiet group, the consumption of olive oil, legumes, fish, and vegetables remained higher (p < 0.01, compared with baseline) and discretionary food consumption remained lower (p = 0.02) at 18 months. These data show that some MedDiet principles could be adhered to for 12 months after finishing the MedLey trial. However, improvements in cardiometabolic health markers, including BP and plasma triglycerides, were not sustained. The results indicate that further dietary support for behaviour change may be beneficial to maintaining high adherence and metabolic benefits of the MedDiet.

The purpose of this investigation was 2-fold: (1) to investigate the effects of a translational 12-week community-based multimodal exercise program on quality of life (QoL) in breast cancer survivors (BCS) and (2) to examine the influence of a start delay on physical function and QoL in BCS. Fifty-two female BCS completed a 12-week program consisting of 90-minute supervised exercise sessions at a frequency of 2 supervised sessions per week. Exercise sessions consisted of three 30-minute components: (1) aerobic conditioning, (2) resistance exercise training, and (3) balance and flexibility training. Significant ( P < .05) improvements in QoL were identified post-program completion. Cohort stratification comparison between the early start (<1 year since completion of oncologic treatment) and late start (>1 year since completion of oncologic treatment) revealed no significant ( P > .05) differences between the early start and late start groups on improvements in physical function. Regarding the influence of start delay on QoL, the early start group showed significant ( P < .05) improvement in emotional well-being. No other significant differences in improvement in QoL were detected between the early start and late start groups. Regardless of start delay, meaningful improvements in physical function and QoL were found after completing the community-based multimodal exercise program. Early participation in community-based exercise programming may benefit BCS’ emotional well-being compared to later participation.

This research aims to find out the improvement of IPA subject learning achievement through a Group Investigation type cooperative learning model. The study was conducted at MIN 5 Gunungkidul with the research subjects of students of class VI of the 2017/2018 School Year. The study uses class action methods including planning, execution, observation, test and documentation activities. The results showed the use of the Group Investigation model can improve IPA learning achievement as evidenced by the average grade in the student class in pre-cycle activities of 69.47 with learning completion of 46.67% with sufficient criteria increased to 74.93 with learning completion by 60% including high criteria in cycle I, and increased to 84.93 with 86.67% learning completion including very high criteria in cycle II. The Group Investigation model can be applied to students at MIN 5 Gunungkidul.

AFTER a period of dramatic growth in school completion in Australia, rates of school retention have begun to decline. At its peak in 1992 the national rate of retention to Year 12 was approximately 77 per cent. By 1995 the rate had fallen to 72 per cent. The aim of this paper is to document state, system, and social differences in the recent downturn in school completion rates in Australia. Data from the Australian Bureau of Statistics and from the Australian Youth Survey are used to look at patterns across states, school systems, geographical locations, social backgrounds, and by sex. The results suggest that during the 1990s the downturn in completion has been uneven and some groups of users which had come to rely on schooling during the 1980s for their future economic security are now turning away from school. The findings indicate a continuing need to monitor the numbers of young people completing school and their backgrounds.

54 Background: Despite primary treatment for localized PC, 20-30% of men experience a BCR, detected by a rise in prostate-specific antigen (PSA). Though 30% of these patients develop metastatic disease, the optimal treatment of men with BCR has yet to be determined. In this trial, we evaluate the efficacy of DOC, BEV, and ADT for men with BCR after local therapy for PC. Methods: 41 men with a BCR and PSA doubling time of ≤10 months (mos) were enrolled. Patients received 4 cycles of DOC (75 mg/m2) every 3 weeks, 8 cycles of BEV (15 mg/kg) every 3 weeks, 18 mos of a luteinizing-hormone releasing hormone (LHRH) agonist, and 15 mos of bicalutamide (50 mg daily) beginning after completion of DOC. The primary endpoint was the proportion of patients free from PSA-progression 1 year after completion of ADT. Secondary endpoints included PSA response, testosterone recovery, and toxicity. Results: Median follow-up was 27.6 mos. Median age at diagnosis was 58 years. Median PSA at diagnosis was 6.7 ng/mL, with the majority of patients (59%) having Gleason 7 disease. Most patients underwent radical prostatectomy +/- radiation therapy (n=36). At baseline, 33 men (81%) had a normal testosterone (> 240 ng/dL). The table describes the PSA responses for the entire cohort. 10 men (28%) had a normal testosterone 6 mos after completing ADT. 17 men (47%) had a normal testosterone 12 mos after completing ADT, of whom 5 (29%) had a PSA <0.2 ng/mL at that time. There were 15% grade 1, 34% grade 2, 39% grade 3, and 12% grade 4 adverse events (AEs). The most frequent grade 3-4 AEs included neutropenia (24%), febrile neutropenia (11%), and hypertension (9%). Conclusions: DOC, BEV, and ADT for BCR resulted in complete responses in 16 men (44%) 1 year after completion of therapy. Longer follow-up is needed to determine the efficacy of this regimen. Clinical trial information: NCT00658697. [Table: see text]

Accelerated partial breast irradiation (APBI) using the implanted brachytherapy device MammoSite® was approved for routine use by the Food and Drug Administration in 2002. The American Society of Breast Surgeons MammoSite® Breast Brachytherapy Registry served as a guideline for our institution to begin offering this treatment in 2005. This report reviews our available data to provide an analysis of patient outcomes over 12 years of use at a single institution. A retrospective review was conducted of records of 150 patients who underwent APBI or attempted APBI after breast-sparing surgeries between 2006 and 2017. These charts were analyzed for documentation of patient age, cancer stage, incidence of recurrence, and posttreatment complications. Of the patients evaluated, 99 per cent (149/150) completed treatment. The median time since treatment completion is now 8.9 years. One hundred eleven patients (74%) are now greater than five years posttreatment. Ipsilateral breast recurrence was found in 2.7 per cent of patients (4/149), and 1.3 per cent of patients (2/149) developed new primary breast tumors. Acute complications, mostly skin erythema (21%), were uncommon and self-limited. Subacute effects were generally fibrosis (13%) and mild local pain (9.4%). APBI for breast cancer after breast-conserving surgery continues to be used at our institution for select patients with good outcomes. Local control and toxicity are similar to that reported in the literature. Five-year local recurrence rates compare favorably with national trials. Occasional complications included fibrosis, persistent pain, and skin irritation.

Background: Appendicectomy is the most common surgical procedure done for acute appendicitis worldwide. However, one among 50000 appendicectomy patients may present with recurrent abdominal pain, requiring hospitalization as stump appendicitis and may need completion appendicectomy. There are a few reports addressing management of stump appendicitis in the literature. Here we present our experience of laparoscopic completion appendicectomy over ten-year duration.Methods: A retrospective evaluation of records of appendicectomy from January 2008 to December 2018. All patients who had stump appendicitis as diagnosis and those who underwent completion appendicectomy were included. There were no exclusions. Details pertaining to presentation, duration of symptoms, records of previous surgery, perioperative and postoperative data was recorded, including follow-up of at least six months.Results: All 15 patients were managed by laparoscopic completion appendicectomy. Patients age range from 12 to 58 years, 12 were males and 3 female, duration of symptoms was from two to ten days, previous appendicectomy was done 4 to 84 months before, nine were diagnosed by ultrasonography of abdomen and six by CT scan, stump size ranged from 1 to 3.6 cm, mean operating time was 86.4 mins (range, 60-120 minutes). Duration of hospital stay was 3 to 5 days. There were no perioperative morbidity or mortality.Conclusions: Laparoscopic approach of completion appendicectomy is safe for management of stump appendicitis.

Incomplete gallbladder removal usually leads to residual gallbladder, which can act as a nidus for stone formation in later life. Stump cholecystitis is a condition in which, such a large gallbladder remnant left after subtotal cholecystectomy becomes inflamed. When this happens, a completion cholecystectomy is advised. We present a rare case of residual gall bladder in a 44-year-old woman who underwent a subtotal cholecystectomy procedure 12 years ago.

Background: Older people consistently report a desire to remain at home. Beat It is a community-based exercise and lifestyle intervention that uses evidence-based strategies to assist older people with type 2 diabetes mellitus (T2DM) to improve physical and functional fitness, which are crucial to maintain independence. This follow up, real-world study assessed the efficacy of Beat It and whether older adults with T2DM were able to maintain improvements in physical activity, waist circumference and fitness one year post completion. Methods: We have previously reported methods and results of short-term outcomes of Beat It. This paper reports anthropometric measurements and physical fitness outcomes of Beat it at 12-months post program completion and compares them to validated standards of fitness required to retain physical independence. Results: Improvements that were observed post program were maintained at 12 months (n = 43). While the number of participants who met fitness standards increased post program, not all increases were maintained at 12 months. Conclusions: This study provides promising early evidence that an eight-week, twenty-hour community-based clinician-led exercise and lifestyle program can improve health outcomes in older adults with T2DM which were retained for at least a year after program completion.

With many libraries in constant transition, continuing education is necessary for library professionals to keep up with trends in library science. This book shows how LIS schools and professional organizations can help information professionals to continue their education after finishing formal programs to keep up with the growing demands of the field. As technology rapidly advances, the need for continuing education increases at an accelerating rate. Within 10-12 years of completing formal education, most information professionals' knowledge and skills become out of date, leaving them only half as able to meet the new demands of the profession.

Abstract In many school districts, the subjects making up a curriculum in any one year rarely have much to do with one another in practice, even if they do in some abstract description of the curriculum. The treatment of a subject in a given year has little to do with its treatment the prior year or with what its treatment will be the following year. Some topics appear year after year at about the same cognitive level and in the same context, whereas some important topics may never show up in any year at all. Perhaps this lack of intellectual and developmental coherence is not surprising since few K-12 curricula have been designed on the basis of a comprehensive, interconnected set of learning goals—not even within subject areas and certainly not across the entire array of subjects. This chapter begins by looking at the idea of curriculum coherence and then goes on to discuss ways in which developmental and intellectual coherence of existing K-12 curricula can be improved. Throughout, the context is science literacy and the examples are mostly taken from the work of Project 2061, but there is no reason to believe that the ideas and procedures would not apply more generally. In the context of this chapter, a coherent curriculum is one that focuses on the relatedness of particular knowledge and skills needed for science literacy, takes developmental considerations into account in deciding on the grade placement of specific learning goals in science, mathematics, and technology, and provides occasions for exploring thematic connections between science-related subjects and other fields. These three aspects of curriculum coherence—literacy goals, developmental sequence, and thematic connections—are discussed below. It is probably true that in every field there is more we would like students to learn than there is time for them to learn—even in the thirteen years from the start of kindergarten to the completion of high school. Surely this is the case with regard to science, mathematics, and technology. Hence great care must be taken to identify a limited set of essential, mutually supportive science-literacy goals to serve as the basis for making curriculum-content decisions.

Abstract The first complete bacterial genome sequence, for Haemophilus influenzae, was published in 1995,1 followed the same year by the sequence for Mycoplasma genitalium. This simple, wall-less organism has one of the smallest genomes, only 580,070 base pairs and carrying just 470 genes. The genome sequence of a cyanobacterium (formerly called a blue-green alga) came in 1996, and in 1997 those for three chief model microbes: Escherichia coli, the workhorse of molecular microbiology; Bacillus subtilis, the model gram-positive bacillus; and baker’s yeast, Saccharomyces cerevisiae, a favorite for studying eukaryote molecular and cell biology. Completion of the yeast sequence was a triumph of organization because it resulted from a cooperation among100 laboratories in Canada, Japan, the United States, and Europe, including a European Union consortium of laboratories from almost every member state. The article in Nature summarizing the results had what may be a record of 633 authors.2 It was by far the largest genome to be completed, with more than 12 mil- lion base pairs of DNA distributed among 16 separate chromosomes, although encoding only about 6000 genes. This is far fewer than in a bacterial chromosome of the same size, because eukaryotic chromosomes contain long stretches of DNA that do not code for proteins. By early 2006, there were 316 complete genomes of bacteria alone, and another 933 were in progress.

ABSTRACT In the period between 1961 and 2008, Oklahoma, USA, averaged about two M ≥3.0 earthquakes per year, with no damage to any built infrastructure. A substantial increase in seismic activity was first observed in 2009, when there were 20 M ≥3.0 earthquakes, and activity peaked in 2015, when over 900 M ≥3.0 earthquakes occurred. Because of the unprecedented increase in seismic activity, the governor’s office of Oklahoma formed a Coordinating Council of researchers, regulators, industry, and other stakeholders in 2015. The Coordinating Council was led by the Secretary of Energy and Environment and charged with understanding and attempting to mitigate (that is, reduce, if not eliminate) induced seismicity and potential impacts. Major outcomes of the coordinated efforts included delineation of an area of interest (AOI) for seismicity in Oklahoma, modifications to underground injection control (UIC) well completion depths and injection rates into UIC wells in the AOI, development of the Oklahoma Well and Seismic Monitoring (OWSM) application used for regulatory oversight and action, modified well completion protocols, a more robust seismic network, and numerous scientific investigations and publications. Because of concerted efforts between regulators and industry, disposal into the Arbuckle Group, the primary zone for wastewater disposal, in the AOI was reduced by more than 50% though oil production continued to increase. Seismic activity decreased over a 6 yr period with 619, 302, 195, 65, 39, and 29 M ≥3.0 earthquakes occurring in 2016, 2017, 2018, 2019, 2020, and 2021, respectively. At the time of latest updates to this chapter (16 October 2022), there have been 12 M ≥3.0 earthquakes and one M ≥4.0 earthquake, so the projected total of M ≥3.0 earthquakes in 2022 is 17. Using these metrics, the coordinated efforts of Oklahoma stakeholders appear to have successfully reduced seismicity with respect to frequency and number in the range of minor but often felt (M 3.0–3.9), light (M 4.0–4.9), and moderate (M 5.0–5.9) earthquakes. So, the Oklahoma case provides examples of how stakeholder action diminished seismic hazards and how similar actions could be used to reduce induced seismicity in other areas where injections occur.

Abstract In the several years following celebration of the Ludi Saeculares, Augustus endured the deaths of several close members of his family: his son-in-law Agrippa, his stepson Drusus, and his younger sister Octavia. These years were also marked by three important public milestones. In 12 b.c., Augustus assumed the position of Pontifex Maximus upon the death of Lepidus. In 11 b.c., Augustus saw to completion the Theater of Marcellus, which commemorated the life of his nephew and son-in-law Marcellus, who had died in 23 b.c. And in 9 b.c., Augustus dedicated the Ara Pacis Augustae, a monument to the Augustan Peace. These three public events were accompanied by meaningful celestial displays that reinforced the connection of Augustus and his family to the celestial sphere.

Abstract As first light broke on New Year’s Day of 1492, Christian forces entered and took Granada, completing the reconquest of Spain from the Moors. Six days later, the newly captured Alhambra palace of the Moors was admired by Queen Isabella and King Ferdinand. Their marriage twentythree years earlier had aligned the major Spanish kingdoms for the first time and after long civil wars, making reconquest possible. On March 30, 1492, Ferdinand and Isabella signed an order expelling another distinct but less foreign group, the Jews, extending and bringing to climax an Inquisition over which the monarchs had been granted control by the pope fourteen years earlier. The year 1492 also saw the printing of the first vernacular grammar book in Spain, under royal approval. And on April 17 of that momentous year, the king and queen dedicated a portion of their new resources to the voyage of Christopher Columbus in search of a western route to India. Columbus departed on August 3 and on October 12 sighted land in what we now know to be the West Indies. Within this ten-month period, a consolidating Spanish state had expelled its Moorish rulers, moved further toward religious unity, begun to spread linguistic homogeneity, and projected itself globally. This was truly a New World, at home and abroad, marking the start at midmillennium of Europe’s emergence into the early modern era.

Benzodiazepines and related compounds (benzodiazepine receptor agonists [BzRAs]) cause a wide range of adverse reactions, including withdrawal symptoms, even when normal or low dosages are used. Deprescribing is recommended when there is loss of efficacy, major side effects, or use longer than four weeks. The withdrawal syndrome is due to physiologic dependence based on various receptor adaptations. Psychological, neurophysiologic, and somatic complaints can be misdiagnosed as psychiatric, psychosomatic, or substance use disorder. These symptoms may be severe and prolonged. The discontinuation process should include careful planning, support, and the use of cognitive behavioral therapy. Tapering, perhaps after substituting with a long-acting BzRA, should be patient-led and proceed slowly, anticipating completion over 12 to 18 months or even longer. In a proportion of patients, symptoms may continue months or years after complete BzRA cessation, requiring ongoing medical care.

This case examines the development of a game design curriculum offered to high school students as an in-school elective course in the Oconomowoc Area School District (OASD), a Wisconsin suburban school district of 5,200 students. Elements of Game Design (EOGD) was created by an Instructional Technology Administrator (ITA), Technical Education (TE) teacher, and Visual Arts (VA) teacher in 2010, and implemented 9 times during the 2011-12 school year. The rationale for proposing the course was based on the overlap of research, trends, and experience studying game-design and game-based learning environments. To that end, it is important to note the ITA was simultaneously completing an educational technology doctoral degree focused on digital media and learning and engaged in research involving Massively Multiplayer Online Games (MMOG) and Augmented Reality Games (ARG).

Abstract The first eleven chapters of this book were devoted to providing a framework for understanding transformations and their impact on long-term organizational success as well as describing tools that can be used for managing these transformations. In this chapter, we present a comprehensive example of a company that has completed several transformations during its sixty-seven-year history and that is currently facing the challenges of completing a compound transformation-from an entrepreneurship to a professionally managed firm as well as a vision transformation. This example is comprehensive in a dual sense. First, because Bell-Carter has been in business since 1912, the company has experienced all the transformations described in this book: (1) entrepreneurial transformations to professional management, including the special case of family business transformations, (2) revitalization transformations, (3) business vision transformations, and even (4) compound transformations. Although our principal interest is in the most recent period of the company’s development (from 1992 through 1997), we also briefly review the earlier periods to both describe the historical development of the firm and illustrate some transformations made at previous points. Figure 12-1 offers a brief overview of the transformations Bell-Carter Olive Company has made during its history.

Abstract The nucleotide sequence of the DNA genome of bacteriophage cpX174 (5386 bp) was determined in 1977 (1), and that of bacteriophage A (48 502 bp) followed in 1982 (2). In these early years of sequencing, virus genomes provided the targets to push the development of nucleotide sequencing technology forward. This situation continued until the completion of the sequences of the genomes of the large DNA viruses such as the herpesviruses and the poxviruses. Notable landmarks have been the first complete sequence of a herpesvirus, varicella zoster virus (124 884 bp) in 1986 (3), and of a poxvirus, vaccinia virus (191636 bp) in 1990 (4). The intervening years have seen the determination of the complete sequences of other members of these families of large viruses, representing examples of different genera and with different hosts. Examples of these for the herpesviruses are human and equine herpes viruses I (5, 6) and II (7, 8), cytomegalovirus (9), HSV 7 (10), channel catfish virus (11); and for the poxviruses, smallpox (12), and molluscum contagiosum virus (13). The sequences of other large DNA virus genomes, such as African swine fever (14), and a baculovirus (15), have also been determined. These projects represent various approaches to the problem; clearly there are alternative strategies that can be employed successfully. Moreover, it is no longer the viruses that provide the targets for the technological push, but the larger genomes of bacteria (16-19) and yeast (20), now superseded by the chromosomes and indeed entire genomes of eukaryotes. The tools currently available to the virus genome sequencer are therefore considerably more powerful than those used to elucidate the first sequences. We can therefore look forward to the routine determination of the sequences of a wide range of large DNA viruses with different host ranges and phenotypes, bringing new opportunities for the study of virus evolution and virus-host interactions.

Solid phase peptide synthesis (SPPS), first proposed by R. B. Merrifield in 1962, has evolved over three decades into a tremendously powerful method for the preparation of peptides and small proteins. An absolute prerequisite for successful syntheses in all solid phase schemes is that reactions which accumulate solid supported products, and by the very nature of the technique contaminating by-products, must proceed cleanly and efficiently. During the earlier years of SPPS this optimal situation was not always achieved, primarily due to contaminated reagents and ill-defined polymers in combination with poorly flexible protection strategies. As the methods of SPPS gained popularity and more widespread application, reagents and protection strategies were improved and refined. However, reports of notable successful syntheses were accompanied by then unexplained failures, which have since been collectively termed ‘difficult peptides’. This chapter describes how an intrinsic understanding behind the occurrence of ‘difficult peptides’ has accumulated, leading to a general synthetic solution—the utilization of a backbone amide protection strategy. Within a few years of the introduction of SPPS, it was recognized that the assembly of some peptide sequences posed a special synthetic problem. The main feature evident during these syntheses was a sudden decrease in reaction kinetics, leading to incomplete amino-acylation by activated amino acid residues. The unreacted sites were readily detected by the Kaiser test for free amine; however, couplings showed no significant improvement even upon repeated or prolonged reaction. Efficient reactions are known to occur within a fully solvated peptide-polymer matrix, where reagent penetration is rapid and unhindered. This optimal situation no longer exists during the assembly of a difficult peptide, where the normally accessible solid phase reaction matrix becomes partially inaccessible during assembly. This situation arises suddenly, typically 6-12 residues into the synthesis, and may then persist for a number of cycles before easing, or in extreme cases remain throughout the completion of the assembly. The crude products are particularly poor if slower coupling β-branched residues (isoleucine, valine, threonine) are introduced after the onset of synthetic difficulties. The principles underlying the occurrence of difficult peptide sequences have for many years been the focus of intense debate and research. An intrinsic feature of the numerous ideas proposed is that aggregation occurs resulting in poor solvation within the peptide-polymer matrix.

Objective: To present a single institutional experience with acute toxicity, patterns of failure and survival in carcinoma cervix treated using definitive radiotherapy with IMRT technique. Methods: It is a retrospective analysis of 64 patients with carcinoma cervix treated with definitive chemoradiation (IMRT) from April 2011 to Jan 2013. Patients with squamous or adenocarcinoma histology and no metastasis, treated with definitive radiotherapy (IMRT) with or without concurrent chemotherapy were included. Acute toxicities were presented as proportions and kaplainmeier computation was done to calculate 3 years disease free survival (DFS) and 3 years overall survival (OS). Results: Median follow up was months for the entire cohort. Mean age was 55.9 years (SD 9.93). Majority of patients (92.8%) had locally advanced disease (FIGO II and III) and squamous cell carcinoma (96.9%). Mean dose to pelvis with IMRT was 49.75 Gy (SD 1.78) followed by ICRT, EBRT boost and implant in 79.7%, 17.2% and 3.1% respectively (as indicated). Response evaluation done at 3 months of treatment completion showed 83.6% complete response, 11.5% partial response and 4.9% progressive disease. During follow up 21.6% developed recurrence - 44.4% failed locally, 16.7% at para-aortic nodal region and 38.9% at distant sites. The 3 year DFS and OS was 70.8% and 60.3% respectively. Patients had tolerable acute toxicities. Incidences of grade ≥3 acute toxicity were 3.1% for anemia, 10.9% for neutropenia, 25% for thrombocytopenia, 1.5% for nausea, 0% for vomiting, 12% for GU and 12% for GI toxicities. Incidence of grade I, II and III radiation dermatitis were 38.89%, 27.78% and 22.2% respectively. None developed grade IV radiation dermatitis. Conclusion: IMRT for carcinoma cervix seems to provide improved outcomes and toxicity profile, although it should be compared with conventional radiotherapy in a well randomized control setting so as to have true and meaningful comparison.

Abstract The United States Navy (USN) 501-K Series Radiological Controls (RADCON) Program was launched in late 2011, in response to the extensive damage caused by participation in Operation Tomodachi. The purpose of this operation was to provide humanitarian relief aid to Japan following a 9.0 magnitude earthquake that struck 231 miles northeast of Tokyo, on the afternoon of March 11, 2011. The earthquake caused a tsunami with 30 foot waves that damaged several nuclear reactors in the area. It was the fourth largest earthquake on record (since 1900) and the largest to hit Japan. On March 12, 2011, the United States Government launched Operation Tomodachi. In all, a total of 24,000 troops, 189 aircraft, 24 naval ships, supported this relief effort, at a cost in excess of $90.0 million. The U.S. Navy provided material support, personnel movement, search and rescue missions and damage surveys. During the operation, 11 gas turbine powered U.S. warships operated within the radioactive plume. As a result, numerous gas turbine engines ingested radiological contaminants and needed to be decontaminated, cleaned, repaired and returned to the Fleet. During the past eight years, the USN has been very proactive and vigilant with their RADCON efforts, and as of the end of calendar year 2019, have successfully completed the 501-K Series portion of the RADCON program. This paper will update an earlier ASME paper that was written on this subject (GT2015-42057) and will summarize the U.S. Navy’s 501-K Series RADCON effort. Included in this discussion will be a summary of the background of Operation Tomodachi, including a discussion of the affected hulls and related gas turbine equipment. In addition, a discussion of the radiological contamination caused by the disaster will be covered and the resultant effect to and the response by the Marine Gas Turbine Program. Furthermore, the authors will discuss what the USN did to remediate the RADCON situation, what means were employed to select a vendor and to set up a RADCON cleaning facility in the United States. And finally, the authors will discuss the dispensation of the 501-K Series RADCON assets that were not returned to service, which include the 501-K17 gas turbine engine, as well as the 250-KS4 gas turbine engine starter. The paper will conclude with a discussion of the results and lessons learned of the program and discuss how the USN was able to process all of their 501-K34 RADCON affected gas turbine engines and return them back to the Fleet in a timely manner.

Abstract Extended reach drilling (ERD) can facilitate the development of untapped resources, reduce greenhouse gas emissions, surface congestion, and drilling costs. This ERD project with lower completion was started with an aim to lower well cost indicators including $/ft and $/bbl. Therefore, the challenge was to drill Slimhole ERD (6-1/8″ lateral) wells with water-based mud (WBM). WBM is more cost-effective, environmentally friendly, and less damaging to the reservoir than OBM (oil-based mud). The use of WBM instead of OBM can save $2MM per well. The major challenges in drilling Slimhole (6-1/8″ size) ERD well with lateral le include higher torque and failure to deploy lower completion due to high friction factors. The first pilot well was planned with a liner-less design considering the low friction factors required to drill 15,000′ of 6-1/8″ lateral hole and run the lower completion. The second pilot well was targeting a deeper and tighter reservoir zone with higher downhole temperatures. This involved drilling 12-1/4″ intermediate hole to the landing point with larger 5-1/2″ drill pipe. It enabled a push-pipe technique for drilling the lateral hole with improved weight transfer through the curved profile. The 6-1/8″ lateral hole was drilled with 4″ high-torque drill pipe, tandem high-flow circulating subs, and specially formulated drilling fluid lubricant. A conventional OBM system provides sufficient lubricity to reduce friction factors as low as 0.10. In this application, a low cost WBM system was made feasible by introducing stable high-temperature lubricant and unique hole cleaning practices. Following this successful achievement, the 5-year business plan has been revised to include 63 similar wells with a projected total savings of ~ $250MM. The Slimhole ERD project has demonstrated substantial value with a 35% reduction in CAPEX. The delivery of these two Slimhole ERD wells overturned conventional drilling and completion practices. The implemented project resulted in saving up to 35% of the well cost and saved 20 days per well compared to a conventional ERD well with 8-1/2″ hole and OBM. These two Slimhole ERD (15,000′ lateral) wells were drilled with a challenging Directional Difficulty Index (DDI) of 7.2. The wells were both completed successfully by running the 4-1/2″ lower completion to reach the total depth.

Aims: Q-LAMP aims to identify risk factors and resilience factors for symptoms of psychiatric illness during the pandemic. Study strengths include the 1-year longitudinal design and the use of standardized instruments already available in English and Arabic. The results will increase understanding of the impact of the pandemic on mental health for better support of the population during the pandemic and in future epidemics. Until an effective vaccine is available or herd immunity is achieved, countries are likely to encounter repeated ‘waves’ of infection. The identification of at-risk groups for mental illness will inform the planning and delivery of individualized treatment including primary prevention. Methodology: Longitudinal online survey; SMS-based recruitment and social media platforms advertisements e.g. Facebook, Instagram; Online consent; Completion time for questionnaires: approx. 20 to 30 minute; Baseline questionnaire with follow up at 3, 6, 9 and 12 months; Study completion date: Sept. 2021. Inclusion criteria: Currently living in Qatar; Qatari residents: citizens and expatriates; Age 18 years; read Arabic or English (questionnaire and consent form available in both languages). Instruments: Sociodemographic questionnaire including personal and family experience of COVID-19 infection; Standard instruments to assess psychiatric morbidity including depression, anxiety and PTSD; research team-designed instruments to assess social impact of pandemic; standard questionnaires to assess resilience, personality, loneliness, religious beliefs and social networks. Results: The analysis was based on 181 observations. Approximately, 3.5% of the sample was from the sms-recruitment method. The sample of completed surveys consisted of 65.0% females and 35.0% males. Qatari respondents comprised 27.0% of the total sample, while 52% of the sample were married, 25% had Grade 12 or lower level of educational attainment, and 46.0% were unemployed. Covid-19 appears to have affected different aspects of people’s lives from personal health to living arrangements, employment, and health of family and friends. Approximately, 41% to 55% of those who responded to the survey perceived changes in their stress levels, mental health, and loneliness to be worse than before the pandemic. Additionally, the wide availability of information about the pandemic on the internet and social media was perceived as source of pandemic-related worries among members of the public. Conclusion: The continued provision of mental health service and educational campaigns about effective stress and mental health management is warranted.

Abstract Design experiences are a critical component of undergraduate STEM education, as they challenge students both academically and socially. The goal of this study is to investigate how previous design experiences and engineering design self-efficacy impact project outcomes for a Hackathon style design project. This early-phase exploratory study observes first-year students in STEM-focused disciplines as they complete a six-hour ‘Hackathon’ style event. The Hackathon serves as the final requirement for the students’ interdisciplinary cornerstone design course. In this study, student demographics, K-12 prior experiences, and engineering design self-efficacy, were collected to understand how these different factors may influence student success throughout the Hackathon. The project is deemed a ‘Hackathon’ due to the problem-focus task given to the student participants and the variety of STEM skills required to arrive at a successful project outcome and a positive student learning experience. The results of the study show significant correlation between the students’ prior exposure to design and engineering content before their undergraduate studies. Significant correlations were also observed between design self-efficacy factors and success in the Hackathon (measured through time of completion at various points). These findings have the potential to influence design pedagogy and team assignment criteria for future iterations of this cornerstone course and other curricular content focused on the engineering design process. The results of this study set the foundation for future work aimed at understanding our first-year engineering students’ prior design experiences and preparing them for academic success during undergraduate education. An extension of this work is planned that will facilitate longitudinal comparisons of achievement and progress across a four-year design experience.

Abstract Since the Tenares infill drilling campaign started in 2021, Fracturing has become Kotabuana field new well primarily Initial Completion (IC) method. The design was set based on the best practice that evolved throughout time since 2018, starting with typically 1300 bbls fracturing fluid, 80,000 lbs of proppant with a typical 7 PPA pumping schedule. During the execution campaign, the fracturing initial completion design and execution was improved by evaluating the post job result correlation towards well property and production result. A key factor in the successful fracturing job is the fracturing model. In improving the fracture modelling, Temperature log was run to validate the 1D Mechanical Earth Model (MEM) by seeing the change in temperature post mini fract to detect the fract height growth. By doing so, the risk of having a premature screen out could be minimized, improving the overall job effectiveness. The necessary additives was also introduced to control the height growth. The type and volume of fracturing fluid and proppant was also improved according to the lessons learned to gain improvement and progression on the optimal fracture design in each execution. Start with one and two-size proppants to get optimal conductivity and decrease fracturing fluid gel loading which can reduce residual fracturing gel. The job performance also highlighted in the aggressiveness of fracturing that compare the PAD ratio used in the execution towards the design by increasing the amount of proppant injected and pad cut. This progression makes the pumping execution reach up to 130.000 lbs of proppants and stage 12 PPA pumping schedule. Numerous improvements were observed during the IC fracturing process. During the sand clean out operation, a more direct approach to the cleaning up operation was employed by maintaining the pressure in the string annulus during 4 of 5 screen-out occasions which successfully reduces the needs for Coiled Tubing Unit (CTU). There are also accumulative works and efforts which successfully optimized the cycle time of fracturing operation by year of execution. Another improvement was the decisive action to conduct re-fracturing execution when a premature screen-out was encountered, improving the total cycle time and workflow. The Fracturing result has been proven to stimulate the productivity index (PI) of the well with a fold of production. Some key lessons learned during the executions were documented which highlight the importance of several key aspects such as temperature log utilization to validate 1D MEM, proppant tapering strategy in pumping schedule, well placement towards the fracturing design and the existence of injector well to provide pressure support in sustaining the well production.

Abstract Many operators have been working on optimizing stage spacing or clusters per stage to maximize production and reduce completion capital investment in unconventional wells. The operator has successfully proved that eXtreme Limited Entry (XLE) design works well in the Bakken. This paper uses a continuous improvement concept to improve on the paper presented in 2020 URTeC: 2796. The objective of this study is to push the boundary of perforation design that has been used as a standard design since 2020 to evaluate the optimum Shots Per Cluster (SPC), the minimum Rate Per Cluster (RPC), and the maximum Clusters Per Stage (CPS) that can still further maximize well production and provide optimum fracture cluster efficiency and Uniformity Index (UI). This paper will also address the comparison between XLE design and other diversion techniques. Through the 3-year journey of understanding and optimizing XLE design, the operator had a total of 4 pads planned as a part of this study. The first 2 pads used to prove the XLE design concept utilized Radio Active (RA) tracer, deployable fiber optic, step down tests, downhole camera, perforation acoustic imaging tool, and production data. The other 2 pads are the observation lateral project [Cipolla et al. 2022] and a permanent fiber project; both projects include lateral bottom hole gauges, offset well fiber optic strain, and permanent fiber along the lateral. This paper uses part of the data from these projects to help validate fracture morphology, rate per cluster, and maximum clusters per stage. The operator uses the Lean continuous improvement and plan-do-check-adjust process to work from the planning to the standardization of the design. RA tracer, step-down test, and deployable fiber optic results show that XLE with 1 Shot Per Foot (SPF) yields high production cluster efficiency of more than 90%, high uniformity index, and comparable production data to the non-XLE design while lowering the completions cost. From the permanent fiber optic data, the results show that the minimum rate per cluster to yield a uniformity index of more than 80% in the Bakken is ~ 5 BPM for 4-1/2" liner and ~6 BPM for 5-1/2" liner. Using a continuous improvement process, the operator adopted the XLE design with 1 SPF as the current completion design standard. This design is proven to yield high productivity and increase asset value by lowering the cost of completions by more than 12%. In the high oil price environment, the XLE design can also be used to maximize asset value by increasing entry points in the well. This leads to an increase in short-term production. Throughout the data gathering and trial process, the operator also gathered novel pressure data allowing for direct measurement of perforation friction, and near-wellbore friction Limited Entry and Extreme Limited Entry Designs

This paper reviews the process of the complete design development, from concept to completion of the largest and most capable fireboats in North America, and among the largest in the world, for the Fire Department of New York (FDNY). The Three Forty-Three is the first of two new fireboats to this design built at Eastern Shipbuilding Inc. of Panama City, Florida and delivered in May 2010. The second vessel is due for completion later in the year. As the result of an international design competition, Robert Allan Ltd. was selected to provide complete engineering and design services for the new boats, from initial concept through detailed engineering design and a comprehensive value engineering process. The scope of services also included the support of FDNY through every stage of major component procurement and the shipbuilding contract award. Robert Allan Ltd.’s shipyard supervisory staff also acted in the capacity of Owner’s Representatives on-site in the shipyard throughout the entire construction process. These major, fast response fireboats were designed to specifically address the fire-fighting and rescue needs of the greater New York harbour, including the New Jersey shore. This includes the capability within the vessel to respond to any CBRN (Chemical, Biological, Radiological, and Nuclear) incident. The fireboats are designed for a response speed of 17.4 knots, with a low-wake, 12 knot cruising/patrol speed. The powering, seakeeping, and wake generation characteristics of the semi-displacement hull form were all verified in an extensive model-testing program. The resulting propulsion system is a unique quadruple screw, CPP configuration. The paper focuses on the various initial studies performed to establish the basic design configuration, the model testing and performance verification process, the value engineering studies performed, the many unique design features of the fire-fighting and emergency response capability of these vessels and the performance trials results. Finally, the challenges of managing a major shipbuilding project for a major civic Government Client such as FDNY concludes the paper.

Abstract This document describes how the use of filter cake breaking fluid pills in non-cemented completions across North Kuwait Jurassic reservoirs increased the well's likelihood to be stimulated and produced. It describes the process to test this innovative solution before a well trial, the wells and environment in which they have been used, and their impact in the well's ability to communicate the borehole with the reservoir. The initial step was to identify which type of mud breaking pills could be used and available in the industry and use the current OBM dispersant pills as found in cement job spacers to enhance cement-reservoir contact. A target well screening was done to wells with possible non-cemented reservoir completions. The detailed operational procedure was then designed to consider the breaker volumes, the composition of the interface's spacer high viscosity pill, and the weight of the displacement fluid to account for the hydrostatic loss in the solids-free breaker volume into each of the wells’ geometries. Finally, these wells were stimulated and tested to identify if the new approach had enabled the wells to be productive and minimize the OBM's damage. The solution has been applied in three barefoot and two multi-stage completion wells. The first well's 380 ft 3-7/8" carbonate reservoir took 18 days to drill using 12.1 ppg OBM. Several calibration trips were done and on the final trip the 30 bbl mud breaking pill was displaced to replace the OBM within the open hole section. Post injectivity tests and an acid treatment, the well's initial production was 3 times the field average with a stabilization above field average gas production. In the second well, the 460 ft 3-7/8" section took 7 days to drill using 11.6 ppg OBM. This fluid was left in the hole to perform the acid treatment without achieving any injectivity. The entire reservoir section was then displaced with the mud breaking solution, for which injectivity and successful acid treatment and N2 activation achieved a final production rate comparable to the offset wells. In the third well, the 684 ft 3-7/8" reservoir took 3 days to drill with a 11.5 ppg OBM, which was displaced with the mud breaking pill using the drilling BHA before pulling it out of the hole. The well achieved immediate injectivity and higher than field average production. The fourth well's 676 ft had a 1578 ft section with a 4-1/2" stuck uncemented liner 1000 ft in the 6" OH. This well was left with 13.6 ppg OBM during 1 year and left unproduced. A reentry was done to mill the shoe, clean the uncased open hole and displace the entire section with 11.6 mud breaking fluid. A posterior injection was successfully applied achieving production results above field average on an area in which local offset wells had deemed the formation as tight. The first multi-stage completion pilot was also trialed, in which the OBM weight was initially lowered from 12 to 8.8 ppg, and then displaced by the breaker fluid prior to set the hanger and activate the packers. Following this implementation, a second well with MSC completion was also performed in a 703 ft, 6" section. After a 19 day soaking period of the breaking fluid in the annulus between the MSC and OH, injectivity and stimulation operations were successfully carried out with low surface pressure requirements. The use of filter cake breaking pills in barefoot wells achieved the purpose of facilitating the communication between the wellbore and the reservoir, requiring lower stimulation pressures, and minimizing formation damages that positively impacted the wells’ productivity.

The Avancemos conditional cash transfer (CCT) program, which has operated since 2006 in Costa Rica, focuses on families living in extreme poverty and social vulnerability with adolescents and youth between the ages of 12 and 25. In August 2015, nearly 157,000 students received the cash transfer upon meeting certain co-responsibilities associated with school attendance and completing the school year in secondary school. Beneficiaries are eligible based on their score in the Target Population Information System (Sistema de Población Objetivo - SIPO), calculated through the Social Information Record (Ficha de Información Social - FIS). To receive the benefit, the mother or guardian of the student needs to sign a contract with the Joint Institute for Social Welfare (Instituto Mixto de Ayuda Social - IMAS) in which they commit to meeting the abovementioned co-responsibilities. Verification of the co-responsibilities is carried out by the IMAS in conjunction with the education centers. The payments are made monthly through a prepaid card issued by the National Bank of Costa Rica (Banco Nacional de Costa Rica - BNCR). This document is part of a series of studies carried out in several countries of Latin America and the Caribbean with the objective of systematizing understanding of the operations of CCTs. The other case studies are available on the IDB´s Conditional Cash Transfers website.

Invasive exotic plant (IEP) species are a significant threat to natural ecosystem integrity and biodiversity, and controlling them is a high priority for the National Park Service. The Northern Colorado Plateau Network (NCPN) selected the early detection of IEPs as one of 11 monitoring protocols to be implemented as part of its long-term monitoring program. We also calculated a patch management index (PMI) to quantify the extent and density of invasive patches into a single value that helps identify the scale of the problem. Park managers can use this tool to help prioritize IEP treatment. At Dinosaur National Monument, the NCPN monitors IEPs in the Green and Yampa river corridors. This report summarizes data from monitoring on the Green River in 2019, and monitoring on the Yampa River in 2017, to represent the completion of the third monitoring rotation of the entire river corridor (2002–2005, 2010–2011, 2017–2019). During surveys conducted from June 26 to July 2, 2019, NCPN staff detected 12 priority IEP species and two non-priority species in a 84.6-hectare (209-acre) area along 74.4 kilometers of the Green River above (“upper”) and below (“low-er”) its confluence with the Yampa. A total of 2,535 IEP patches were detected. Of those patches, 24.2% and 15.6% were smaller than 40 m2 on the upper and lower Green River reaches, respectively. The patch management index (PMI) was low or very low for 95.7% of patches on the upper Green River and 90.9% of patches on the lower Green River. Tamarisk (Tamarix sp.), broad-leaf pepperwort (Lepidium latifolium), and yellow sweetclover (Meli-lotus officinalis) were the most widespread species. For the first time, NCPN monitoring detected teasel (Dipsacus sylvestris) on the upper Green River. Yellow sweetclover has increased on all three river reaches during the survey years. Musk thistle (Carduus nutans) was found at considerably lower levels than yellow sweetclover but has also increased on all three river reaches. Leafy spurge is increasing on the lower Green River and Yampa River. Cheatgrass was not monitored in the first rotation, but increased substantially in cover and percent frequency on all three river sections from 2010–2011 to 2017–2019. This increase may be due to a lack of recent high-flow scouring events. The highly regulated upper Green River generally has the highest number of IEPs, while the lower Green River has a moderate amount of IEPs. The largely unregulated flows of the Yampa River continue to result in a lower number of patches per kilometer, lower percent cover, and lower percent frequency than the upper or lower Green River. Network staff will return to the monument in 2022 to begin the fourth monitoring rotation.
