Frictional amyloidosis in Oman - A study of ten cases  

Directory of Open Access Journals (Sweden)

Full Text Available Macular amyloidosis is an important cause for cutaneous pigmentation, the aetiology of which is poorly understood. Friction has recently been implicated the causation of early lesions, referred to as frictional amyloidosis. Confirmation of diagnosis by the detect on of amyloid using histochemical stains is inconsistent. Ten patients with pigmentation suggestive of macular amyloidosis were studied with detailed history, clinical examination, biopsy for histochemistry and electron microscopy. Nine out of ten patients had a history of prolonged friction with various objects such as bath sponges, brushes, towels, plant sticks and leaves. Amyloid was demonstrated by histochemical staining in only six out of ten cases. In the remaining four cases, amyloid was detected by electron microscopy. These consisted of aggregates of non-branching, extracellular, intertwining fibres measuring between 200-500 nm in length and between 20-25 nm in diameter. The study confirms the role of friction in the causation of this condition. Histochemical stains are not always successful in the detection of amyloid and electron microscopy is helpful for confirming its presence. The term frictional amyloidosis aptly describes the condition.

Adolescent cancer patients' perspectives on their educational experiences: Ten case studies  

Science.gov (United States)

The goal of this study was to explore the educational experiences of adolescent cancer patients in treatment for cancer and enrolled in hospital, homebound, or community schools. The incidence of students who have or had cancer is becoming more prevalent in schools today because of increases in the population, the incidence rate of cancer, and the survival rate of cancer. The number of students surviving cancer has increased over 41% in the past ten years and underscores the importance of assuring an excellent education to children and adolescents with cancer so that they may enjoy a good quality of life as long-term survivors. This study explored the educational experiences of students who were adolescent cancer patients and identified educational and psychosocial issues important to their success. The goal of this research effort was to provide educators and medical staff with a deeper understanding of the unique psychoeducational needs of this population and to provide a foundation for developing ideas for improving the educational programs and support available to students who continue their middle and high school education while undergoing treatment for cancer. Participants included ten cancer patient whose mean age at onset of disease was 13.8 +/- 1.7 years, and mean age at interview was 15.2 +/- 1.8 years. The researcher conducted individual, in-depth, ethnographic interviews of students, and one parent and one teacher of each student. Case studies of the students included extensive dialogue of each of the contributing participants. An analysis of the case studies was conducted by coding emerging themes so that topics could be fully explored and compared between individuals, groups of individuals, and educational settings to identify the meaning that these students placed on the educational and psychosocial issues that they voiced as important. Advantages and disadvantages of each educational situation, homebound, hospital school, and community school, were compared. Psychosocial issues related to education were discussed. Additional findings included information about student computer use and information gathering, and the effects of cancer treatment on student interest in science and future occupational plans.

Making a difference: Ten case studies of DSM/IRP interactive efforts and related advocacy group activities  

Energy Technology Data Exchange (ETDEWEB)

This report discusses the activities of organizations that seek to promote integrated resource planning and aggressive, cost-effective demand-side management by utilities. The activities of such groups -- here called energy efficiency advocacy groups (EEAGs) -- are examined in ten detailed am studies. Nine of the cases involve some form of interactive effort between investor-owned electric utilities and non-utility to develop policies, plans, or programs cooperatively. Many but not all of the interactive efforts examined are formal collaboratives. In addition, all ten cases include discussion of other EEAG activities, such as coalition-building, research, participation in statewide energy planning, and intervention in regulatory proceedings.

Chordoid meningioma: a report of ten cases.  

Science.gov (United States)

Chordoid meningioma is a rare variant of meningioma with histological features resembling those of chordoma. This tumor has a great risk of recurrence and aggressive growth (WHO grade II). This study was done to document the clinical and pathological features of ten patients with chordoid meningioma who submitted to surgery at the National Institute of Neurology and Neurosurgery in Mexico City. Clinical, histological and immunohistochemical features were examined. The age range was from 30 to 67 years old (mean, 34.2 years). Seven patients were female and three male. The duration of symptoms varied from 3.5 months to 5 years (mean, 14.1 months). No systemic symptoms were noted. The tumor was localized in eight cases in the supratentorial compartments. Histologically, the tumors were characterized by strands and cords of meningothelial cells arranged in a mucinous stroma. Two of the ten tumors showed metaplasic changes, and seven showed brain invasion. Tumor cells demonstrated CK7, EMA and focal S-100 protein and Ep-CAM. Cytokeratin AE1/AE3, GFAP and synaptophysin were negative. The MIB-1 proliferative index was from 6 to 9% (mean 7.8). PCNA Li was 6 to 20% (mean, 14), and microvascular density was 6-16 (mean, 14.5). The mean rate of the MIB-1 labeling index in recurrences was 7.1% versus 6.33% for no tumor recurrence. Chordoid meningioma, World Health Organization grade II, is an uncommon variant of meningioma with a propensity for aggressive behavior and increased likelihood of recurrence. Chordoid meningiomas are predominantly tumors of young adults with a predilection for the supratentorial location. Intraventricular location and absence of systemic manifestations, despite the presence of abundant B-lymphocytes, mast cells and low MIB-1 LI, are some of the interesting findings in the present series that need further study. Hence, a larger number of cases with adequate follow-up data need to be studied further to establish the clinical relevance of this variant. PMID:20094774

[Current treatment of chylothorax: a report of ten cases].  

Science.gov (United States)

Chylothorax is an uncommon disease resulting from many factors, all of which cause damage to the thoracic duct or its main collectors. The incidence of this disease has increased over the years due to increasing heart and thoracic surgery, in these cases ranging from 0.2% to 0.5%. Its aetiology also includes thoracic traumatic injury, lymphatic neoplasms and inflammatory disease. Over the period considered we observed more than 9000 thoracic patients, ten of whom presented chylothorax, due to a variety of causes. Diagnostic instrumental procedures and clinical investigations enabled us to develop a personalised therapeutic strategy for each case, related to the particular causes responsible for the condition. Most of the patients observed were treated successfully with a non-invasive approach. In two cases surgery (duct ligature and lymphangioma debulking) was performed with positive results. The postoperative course was uneventful with an average hospital stay of 13 days (range: 7-24 days). PMID:16729608

Gastric metastases. An endoscopic series of ten cases.  

Science.gov (United States)

We report a series of ten cases of the clinical, endoscopic and pathological features of gastric metastases. Patients were six women and four men between 54 and 88 years old, with gastric metastases from breast carcinoma (4), lung carcinoma (4) and melanoma (2). Patients underwent an upper gastrointestinal endoscopy for epigastralgia (2), hematemesis (2), dysphagia (1) and anemia (5). On endoscopy, tumors appeared as nodules with a central ulceration (5), an ulceration (4) or simulating linitis plastica (1). Metastases were located in the cardia (2), fundus (5) and antrum (3). Primary tumors had been diagnosed between one day and 20 years before upper endoscopy. Eight patients had multivisceral metastases. The microscopic features of the gastric metastases resembled a primary gastric cancer in eight cases. Thanks to clinical data, the pathologist confirmed the diagnosis of gastric metastases on immunohistochemistry. Nine patients died in the eight-month follow-up period. Gastric metastases are rare, occur at a late stage of the neoplastic disease, and have a poor prognosis. Diagnosis of gastric metastases is difficult because they simulate primary gastric cancer on endoscopy and on microscopic examination. A correct diagnosis is based on good communication between gastroenterologists and pathologists. PMID:20627637

Lessons learnt from ten performance assessment studies  

International Nuclear Information System (INIS)

The management of radioactive wastes and, in particular, the safety assessment of radioactive waste disposal systems are areas of high priority in the programme of the OECD Nuclear Energy Agency (NEA). In 1994, a Working Group was set up under the PAAG (Performance Assessment Advisory Group) on Integrated Performance Assessments of Deep Repositories (IPAG). The aim of the group is to provide a forum for informed discussion on performance assessment (PA), and to examine the overall status of PA and specific issues identified by the group and the PAAG. This document presents the report of a first phase of work completed in December 1996 and is expected to be of most interest to practitioners of repository PA and those with an interest in technical review of PA studies.

Recurrent pulmonary hydatid disease. Analysis of ten cases  

International Nuclear Information System (INIS)

The purpose of this study was to investigate the incidence and define the importance of recurrent pulmonary hydatid cysts in developing countries. We analyzed the records of 312 patients with pulmonary hydatid cyst disease diagnosed in our center between 1999 and 2005. A recurrent pulmonary hydatid cyst was diagnosed in 10 (3.2%) of the 312 patients [8 men and 2 women, mean age 36.9 (range 20-60) years]. The diagnosis was based on radiographic, clinical, or serological findings, established intraoperatively. The most frequent symptom of recurrent pulmonary hydatid cyst was hemoptysis (60%). The mean interval between diagnosis of the initial hydatid cyst and detection of recurrence was 8.75 (range 3-15) years. Bronchoscopy was performed in all patients, but proved diagnostic in only one. The localization of the initial and recurrent cysts differed in seven patients. A median follow-up period of 5 years revealed second recurrences in only two patients; manifesting as an intrapleural rupture of the cyst in one and as empyema in one. The recurrence was treated by resection in all patients; as cystectomy in eight patients, lobectomy in one patient, and pneumonectomy in one patient. Pulmonary hydatid cyst may recur in the same or a different location in the lung. Patients with a pleural lesion must be followed up regularly for any signs of recurrence. (author)

Primary localized conjunctival amyloidosis: A case report with a ten-year follow-up period  

Directory of Open Access Journals (Sweden)

Full Text Available Juan Carlos Mesa-Gutiérrez, Tomás Martí Huguet, Noemí Barnils Garcia, Jorge Arruga GinebredaDepartment of Ophthalmology, Hospital Universitari de Bellvitge, L’Hospitalet de Llobregat, Barcelona, SpainAbstract: A 57-year-old woman consulted our department about a plaque that had been present in her left eye for one year. Ophthalmological examination revealed a solid mass in the left conjunctival semilunar fold. An excitional biopsy was peformed, revealing an amyloid deposition. The patient was referred to the Internal Medicine Department for systemic study. All studies were negative for systemic amyloidosis. Throughout ten years of follow-up study, the patient has shown neither conjunctival recurrence nor any evidence of systemic amylodosis. Despite the fact that several authors have described ocular amyloidosis as an ophthalmologic manifestation of systemic amyloidosis, conjunctival location of amyloidosis is a very rare condition. Amyloid characterization in ocular structures should not be considered a final diagnosis since involvement of systemic underlying diseases must be ruled out. We report a case of localized conjunctival amyloidosis with a ten-year follow-up period that excluded ocular or systemic diseases.Keywords: conjuctival amyloidosis, ocular amyloidosis, hyaline protein

Calcific myonecrosis: A report of ten new cases with an emphasis on MR imaging  

Energy Technology Data Exchange (ETDEWEB)

The aim of this study is to report the typical radiographic and MR imaging features of calcific myonecrosis, which help to distinguish this rare entity from other causes of a calcifying calf mass. Ten patients with a final diagnosis of calcific myonecrosis were referred to a specialist orthopaedic oncology service in a 5-year period with the presumptive diagnosis of malignancy based on recent clinical presentation and imaging findings. Radiographs were available for retrospective review in all ten cases and MR imaging in six. All patients presented with a slow-growing painless calf mass. All gave a history of major trauma to the lower leg many years before, but in only two cases did the referring clinician query whether trauma might be a contributory factor. Radiographs showed well-defined fusiform mineralised masses up to 25 cm in length arising within the calf. The calcification was consistently peripheral and plaque-like. Ossification was not present. MR imaging showed the anterior compartment to be involved in four cases and all compartments in two. T1- and T2-weighted images showed peripheral low signal intensity, more prominent on the T2-weighted images, because of the peripheral mineralization. The contents of the masses were variable on T1-weighted images depending on the differing amounts of blood breakdown products and were heterogeneous on T2-weighted images. The latter may be explained by a combination of the mineralisation and T2 shortening due to blood breakdown products. A gadolinium chelate, administered in two cases, failed to show any appreciable enhancement. Calcific myonecrosis has characteristic clinical, radiographic and MR features that should make the condition easy to recognise. Despite its rarity, it should be included in the differential diagnosis of focal mineralisation of the calf. (orig.)

Monoamine oxidase inhibitors: ten years of docking studies.  

Science.gov (United States)

The number of papers dealing with the structure-based drug design is continuously growing, which demonstrates the importance of such tools in medicinal chemistry. In the current paper, the published literature concerning the use of the ligand-protein docking methodologies in the study of the monoamine oxidase (MAO) enzymes was reviewed. Ten years of studies aimed at developing new compounds active as MAO inhibitors (MAOIs) were covered. The literature regarding thiazole, caffeine, pyrazole, chromone, indeno-pyridazin, ?-carboline, indole, coumarin, anilide and amphetamine derivatives, was discussed in some detail. It is apparent that, through this computational approach, more selective and potent molecules can be proposed as inhibitors by applying precise modifications on the basic scaffold. PMID:23231393

Use of interactive lecture demonstrations: A ten year study  

Science.gov (United States)

The widely held constructivist view of learning advocates student engagement via interactivity. Within the physics education research community, several specific interactive strategies have been developed to enhance conceptual understanding. One such strategy, the Interactive Lecture Demonstration (ILD) is designed for large lecture classes and, if measured using specific conceptual surveys, is purported to provide learning gains of up to 80%. This paper reports on learning gains for two different Projects over ten years. In Project 1, the ILDs were implemented from 1999 to 2001 with students who had successfully completed senior high school physics. The learning gains for students not exposed to the ILDs were in the range 13% to 16% while those for students exposed to the ILDs was 31% to 50%. In Project 2, the ILDs were implemented from 2007 to 2009 with students who had not studied senior high school physics. Since the use of ILDs in Project 1 had produced positive results, ethical considerations dictated that all students be exposed to ILDs. The learning gains were from 28% to 42%. On the one hand it is pleasing to note that there is an increase in learning gains, yet on the other, we note that the gains are nowhere near the claimed 80%. This paper also reports on teacher experiences of using the ILDs, in Project 2.

A retrospective study of the pattern of sexually transmitted diseases during a ten-year period  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Proper knowledge of the patterns of sexually transmitted diseases (STDs in different geographical regions is necessary for evolving proper strategies for control of these diseases. Aims: To study the pattern of STDs and to analyze the changes during a ten-year period from 1990 among patients attending Medical College Hospital, Kottayam Methods: Case records of 686 patients with STDs who attended the outpatient wing of the Department of Dermatology and Venereology were studied. Results: There were 504 males and 182 females in the total of 686 patients. Marital contact alone was reported by 123 (67.6% female patients. Genital ulcer diseases (GUDs accounted for the maximum number of STDs, with 504 cases (73.5%, followed by condyloma acuminatum (17.5% and gonorrhea (10.1%. Forty-three patients had multiple infections. The total number of patients during the first year of study was 129, while it was 41 during the last year. Bacterial STDs showed a striking reduction in numbers. The decline was less marked in the case of viral STDs. Conclusion: The majority of patients had genital ulcer diseases. Spouses were the most common source of infection for female patients. There was a marked decline in the number of patients with various STDs during the ten-year period. The decline was more evident in the bacterial STDs resulting in an apparent increase of the viral STDs towards the end of the period of study.

Ganglion cysts at the gastrocnemius origin: a series of ten cases  

Energy Technology Data Exchange (ETDEWEB)

To describe ganglion cysts arising close to the origin of the medial and lateral head of gastrocnemius as identified on magnetic resonance (MR) imaging. We present a series of ten cases of ganglion cysts arising close to the gastrocnemius origin from the medial and lateral femoral condyles. These were collected over a 6-year period from our imaging database. All patients attended for routine MR imaging of the knee with a variety of clinical presentations. Data collected included patient demographics, ganglion size, ganglion site, clinical presentation and ancillary MR imaging findings. The ten patients in this series consisted of seven males and three females, five right and five left knees, age range 27-68 years, mean age 40.6 years. The mean maximal dimension of the ganglion cysts was 26 mm, range 15-40 mm. The medial gastrocnemius origin was involved in eight patients and the lateral origin in two patients. The MR imaging findings consisted of both uni- and multi-loculated cysts, often containing numerous septations with fluid signal characteristics. The cysts were extra-capsular with no clear communication with the joint. One patient presented with a popliteal soft tissue mass and none of the cases required surgical intervention for cyst removal.

Neutron therapy of low grade 'pencil' gliomas of the spinal cord: A review of ten cases  

International Nuclear Information System (INIS)

Between 1980 and 1986 ten patients (two males, eight females, median age: 35 years) with spongioblastomas and ependymomas grade I of the spinal cord were treated with fast neutrons from the d(14)+Be reaction after incomplete tumour surgery. Eight patients received three weekly fractions of 0.7 to 1.33 Gy and two patients four weekly fractions of 0.8 Gy to total doses of 7.4 to 10.4 Gy. Two complete and six partial remissions of ataxia and motor disturbances were observed. Bladder dysfunctions in five patients cleared up partially in three cases. In two patients the symptomatology remained unchanged. After a follow-up of eight to 88 months two initially complete and two out of six partial remission were maintained. No severe late effects of the skin have been determined. In summary it is concluded that for incompletely resected 'pencil'-gliomas fast neutrons therapy seems to be a feasible treatment modality.

Ganglion cysts at the gastrocnemius origin: a series of ten cases  

International Nuclear Information System (INIS)

To describe ganglion cysts arising close to the origin of the medial and lateral head of gastrocnemius as identified on magnetic resonance (MR) imaging. We present a series of ten cases of ganglion cysts arising close to the gastrocnemius origin from the medial and lateral femoral condyles. These were collected over a 6-year period from our imaging database. All patients attended for routine MR imaging of the knee with a variety of clinical presentations. Data collected included patient demographics, ganglion size, ganglion site, clinical presentation and ancillary MR imaging findings. The ten patients in this series consisted of seven males and three females, five right and five left knees, age range 27-68 years, mean age 40.6 years. The mean maximal dimension of the ganglion cysts was 26 mm, range 15-40 mm. The medial gastrocnemius origin was involved in eight patients and the lateral origin in two patients. The MR imaging findings consisted of both uni- and multi-loculated cysts, often containing numerous septations with fluid signal characteristics. The cysts were extra-capsular with no clear communication with the joint. One patient presented with a popliteal soft tissue mass and none of the cases required surgical intervention for cyst removal. MR imaging may identify ganglion cysts arising in an intra- or extra-articular site around the knee. This series documents the MR imaging characteristics of ganglion cysts arising close to the gastrocnemius origin and dis close to the gastrocnemius origin and discusses the relevance of this imaging finding.

Ten years of Developing International Volcanology Graduate Study Programs  

Science.gov (United States)

In 2000 I reported at this symposium about multi-institutional graduate field trips to IAVCEI events, such as the Bali meeting and its importance in building international collegiality and awareness among the volcanology doctoral students. NSF was an enthusiastic supporter of these field sessions and this support has continued through the highly successful Pucon and Reykjavik sessions. International volcanology graduate program development began with several exchange programs. EHaz was a highly successful program (McGill, Simon Fraser, Michigan Tech, Buffalo, UNAM and Universidad de Colima) funded by the Department of Education (FIPSE) that moved students across North America where dozens of graduate students spent semesters of their study abroad and shared annual field trips and online student led graduate seminar classes. Michigan Tech’s volcanology graduate program started a Masters International program that combined Peace Corps service with hazards mitigation graduate study and students were placed by Peace Corps in countries with prominent natural hazards. The new program funded 2 year residences in foreign environments, principally in Pacific Latin America. NSF strongly supported this program from its inception, and eventually it gained NSF PIRE support. Dozens of students have initiated the 3 year program (15 completed) to date. A similar PIRE developed at UAF with a link to volcanology in the Russian Far East. One gain is the development of many socially-conscious research selections. Beginning this year transatlantic dual degree masters programs in volcanology are being offered by a consortium of US and European volcanology programs (Michigan Tech, Buffalo, Clermont Ferrand and University of Milan Bicocca), again aided by FIPSE funding. Students have dual advisors on both sides of the Atlantic and spend about half of their two year programs in Europe and half in US. Faculty also travel in the program and the four campuses are increasingly linked by coursework and research networks. Because the international developments of volcanology programs address the need for more robust coursework and research choices for students than are possible on one campus, and because they lead to a diverse network of professional contacts , we think the next decade will bring many more multi-university volcanology programs linked to field sites all over the world.

Prognostic factors in children with acute lymphoblastic leukemia: a ten year study  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Acute lymphoblastic leukemia (ALL is the most common cancer in the pediatric population. With modern treatments, the chance of the complete recovery is nearly 100%. The most important prognostic factors are appropriate treatment protocol and determination of patient risk factors based on clinical, morphological, immunological and cytological characteristics. In this study we reviewed frequency of these factors, like as age, gender, the primary white blood cell number, sub- group on the base of FAB classification, immunophenotype and the clinical progress. Methods: In this retrospective study, we reviewed 877 pediatric patients with the diagnosis of ALL between the years of 1994 and 2004. In these patients the age, gender, primary WBC count, sub-group based on the FAB classification, immunophenotype and the clinical progress in 177 patient with acute lymphoblastic leukemia at Imam Khomeini Hospital between the years of 1994 to 2004 were determined. Results: Of these patients, 1.6% was younger than one year, 24.8% more than ten years old and 73.6% were between the ages of one and ten years; 63.8% were male. WBC counts were above 50,000/ul in 28.8% of the patients. FAB classifications included L1 in 80.2%, L2 in 17.5% and L3 in 2.3% of the patients. Immunophenotypes included pre-B cell in 63.8%, early pre-B cell in 23.1%, T cell in 12.3% and mature B cell in 0.8% of the patients. Marker CD10+ was detected in 88.1% of the B cell cases. In this study group, 74% of the patients recovered, 16.3% died and 16.5% relapsed.Conclusions: The prevalence of FAB-L1 and pre-B cell cases in this study is greater than a previous study, while the prevalence of FAB-L2 and early pre-B cell cases is less than that of the previous study.

Ten cases of advanced uterine cervical carcinoma treated by radiohyperthermia and followed over five years  

Energy Technology Data Exchange (ETDEWEB)

The treatment of locally or regionally advanced carcinoma of the uterine cervix is still controversial. We present here ten advanced primary cases of uterine cervical squamous carcinomas treated between 1991 to 1992. The pelvic doses were 54.7{+-}3.8 Gy externally and 25.7{+-}2.7 Gy (point A) intracavitary. Hyperthermia (HT) was performed using a Thermotron RF8, and the effective heating times (>41 degC) was 202.4{+-}44.0 min/6.6{+-}0.8 sessions. The mean over-all treatment period was 59.4{+-}8.8 days. Acute adverse effects were observed in two patients, including umbilical burning and a subcutaneous consolidation cranial to the pubic bone. All the stage III patients (N=7) were locally controlled during their follow-up period. The overall 5-year survival rates for stages III and IVa (N=3) were 50% and 33%, respectively. The later results were relatively good in patients who did not develop hematogenous metastasis. The treatment administered was effective for the local control of stage III disease, but not for systemic control. Therefore, a new protocol for radio-chemo-hyperthermia is necessary for improving the survival rates. (author)

Mature cystic teratomas (MCT) with atypical MR findings. Ten cases with comparison of MR, CT, and pathologic features  

Energy Technology Data Exchange (ETDEWEB)

MRI of ten atypical MCT were reviewed correlating with pathology and to clarify why they did not include any hyperintense area on T1-weighted images (T1WI). Nine of the ten cases had a few sebaceous glands. Intra-tumoral chemical shift artifact was noted in four and the presence of the finding was diagnostic of the disease. Two with abundant thyroid tissue showed multilocular cyst whose fluid in some loculi indicated hyperintense on T1WI and hypointense on T2WI, which was similar to MR findings of struma ovarii. Four with complication such as hemorrhagic necrosis demonstrated inhomogeneous signals and they were hardly diagnosed correctly. (author)

Ten cases of metastatic cervical cancer with the treatment of permanent 125I seeds interstitial implants  

International Nuclear Information System (INIS)

Objective: To investigate the clinical effect of permanent 125I seeds interstitial implants for metastatic cervical cancer. Methods: Under the guidance of the B-sonography, 125I seeds were implanted into the eleven cervical lymph nodes of ten patients who had been given tumor resection. The pain relief and tumor size were observed in regular follow-up after one-month treatment. Results: All the patients were followed up for 6-14 months,and the postoperative recovery was good with no complication. One month after the implantation, the pain symptom was alleviated entirely in two nodes and partly in nine nodes. The tumor size shrank in ten nodes while there was no change in one node after one month. Conclusion: Permanent 125I seeds interstitial implants for metastatic cervical cancer is a safe, minimally invasive and effective treatment. (authors)

Ten years of tuberculosis intervention in Greenland – has it prevented cases of childhood tuberculosis?  

Directory of Open Access Journals (Sweden)

Full Text Available Background: The incidence of tuberculosis (TB disease in Greenland doubled in the 1990s. To combat the increase, national TB interventions were initiated in 2000 and strengthened in 2007. Objective: To determine whether the effect of interventions could be detected, we estimated the TB disease risk among children?15 years before and after interventions were implemented. Design: For a study cohort, we recruited all children ?15 years of age included in the Greenlandic Civil Registration System (CRS from 1990 to 2010. The CRS identifier was used to link cohort participants with TB cases identified based on the Greenlandic National TB registry. Bacille Calmette Guerin (BCG vaccination status was identified through year of birth, as BCG was offered to newborns born either before 1991 or after 1996. Years with interventions were defined as 2000–2006 (primary interventions and 2007–2010 (intensified interventions. Risk of TB was estimated using Poisson regression. Results: The study included 35,858 children, of whom 209 had TB disease. The TB disease incidence decreased after interventions were implemented (2007–2010: IRR [incidence rate ratios] 0.62, 95% CI: 0.39–0.95, p=0.03, compared with the 1995–1999 period. The TB disease risk was inversely associated with BCG vaccination (IRR: 0.54, 95% CI: 0.41–0.72, p<0.001. Conclusions: Years with national TB interventions in Greenland, including neonate BCG vaccination, are associated with a lower TB disease incidence among children ?15 years of age.

Aortopulmonary septal defects. A review of the literature and report of ten cases.  

Science.gov (United States)

From 1981 to 1992, 10 infants with aortopulmonary septal defect (APSD) underwent surgical repair. The mean age at operation was 5.6 +/- 5.5 months, and the mean weight 4.6 +/- 2 kg. Intracardiac associated anomalies were as follows: ventricular septal defects (7 cases), tetralogy of Fallot (2 cases), aortic valve stenosis (2 cases), atrial septal defect (3 cases), patent ductus arteriosus (3 cases), pulmonary valve stenosis (1 case). Cardiac catheterization was performed in 8 out of 10 patients. Eight patients had type I (proximal) defect, 1 had type II (distal) defect and 1 had type III (absent aortopulmonary septation) defect. A variety of surgical procedure was employed. APSD closure with hemoclip was feasible in 3 cases with small window. In 6 patients, during a period of cardiopulmonary by-pass, a side biting clamp was positioned on the ascending aorta close the defect; the border of the window was divided leaving a flap of pulmonary wall on the left side to close the aortic defect; the pulmonary artery was repaired by an autologous pericardial patch. In the patient with type III APSD, aortopulmonary septation was carried out through a transwindow approach. Associated anomalies were repaired in all infants except one. Hospital mortality was 10% (1 case). No late deaths occurred. At a mean follow-up of 47 +/- 35 months 8 patients are asymptomatic and 1 is awaiting for repair of associated anomalies. Conclusions. APSD is a rare but nonetheless well identifiable anomaly. Surgery is indicated as soon as the diagnosis is established, regardless of the patient's age.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8040168

Mucinous carcinoid of the ovary: report of a case with metastasis in the contralateral ovary after ten years  

Directory of Open Access Journals (Sweden)

Full Text Available Monodermal teratomas of the ovary can take the form of carcinoid tumors of which there are several types, mucinous carcinoid being the least common. Very few cases of primary mucinous carcinoid of the ovary have been reported in the literature and the behavior of these tumors over the long term is unclear. We describe a case of primary mucinous carcinoid of the ovary in a 39-year-old woman treated with unilateral salpingo-oophorectomy, where a metastasis occurred in the contralateral ovary ten years later. This case demonstrates that mucinous carcinoid of the ovary can metastasize even after a long interval, and careful follow-up of patients, particularly those treated conservatively, is appropriate.

Directory of Open Access Journals (Sweden)

Full Text Available Objective: To assess safety, efficacy and impact on survival of low anterior en bloc resection (modified posterior pelvic exenteration as part of optimal debulking for primary advanced ovarian cancer. Methods: Complete follow-up data were available for 17 patients who underwent this surgical procedure for advanced ovarian cancer between January 1996 and June 2006. The median age was 58 years (24 to 77. All had epithelial cancer. Seven patients underwent primary debulking, and ten patients underwent interval debulking. All patients underwent optimal cytoreduction (less than 1 cm residual disease and received postoperative platinum-based chemotherapy. Rresults: The postoperative mortality was 0%, while the overall major morbidity was 23.52% (n = 4. Residual disease after debulking was less than 1 cm in four patients, and was microscopic in 13 patients. The overall three-year survival rate was 76.47%, and the median survival time was 32 months. Cconclusions: When necessary, low anterior en bloc resection (modified posterior pelvic exenteration should not be an obstacle against optimal surgery. The morbidity rate was high, but the mortality rate was 0%. Long-term survival may ensue from this approach.

A TLC chemical screening of the extracts was carried out to detect the major chemical classes present in the plants. The data of the traditional medicine were confirmed, since eight plants out of ten were active, aqueous and ethanolic extracts being the most active. Moreover, only C. podolaena leaf extracts were cytotoxic (87% of inhibition on KB. This work opens the way for the research of the active molecules from these plants and for their use as leads in the synthesis and the pharmacomodulation of compounds with analgesic potentiality.

In vitro antimicrobial activity of ten medicinal plants against clinical isolates of oral cancer cases  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Suppression of immune system in treated cancer patients may lead to secondary infections that obviate the need of antibiotics. In the present study, an attempt was made to understand the occurrence of secondary infections in immuno-suppressed patients along with herbal control of these infections with the following objectives to: (a isolate the microbial species from the treated oral cancer patients along with the estimation of absolute neutrophile counts of patients (b assess the in vitro antimicrobial activity medicinal plants against the above clinical isolates. Methods Blood and oral swab cultures were taken from 40 oral cancer patients undergoing treatment in the radiotherapy unit of Regional Cancer Institute, Pt. B.D.S. Health University, Rohtak, Haryana. Clinical isolates were identified by following general microbiological, staining and biochemical methods. The absolute neutrophile counts were done by following the standard methods. The medicinal plants selected for antimicrobial activity analysis were Asphodelus tenuifolius Cav., Asparagus racemosus Willd., Balanites aegyptiaca L., Cestrum diurnum L., Cordia dichotoma G. Forst, Eclipta alba L., Murraya koenigii (L. Spreng. , Pedalium murex L., Ricinus communis L. and Trigonella foenum graecum L. The antimicrobial efficacy of medicinal plants was evaluated by modified Kirby-Bauer disc diffusion method. MIC and MFC were investigated by serial two fold microbroth dilution method. Results Prevalent bacterial pathogens isolated were Staphylococcus aureus (23.2%, Escherichia coli (15.62%, Staphylococcus epidermidis (12.5%, Pseudomonas aeruginosa (9.37%, Klebsiella pneumonia (7.81%, Proteus mirabilis (3.6%, Proteus vulgaris (4.2% and the fungal pathogens were Candida albicans (14.6%, Aspergillus fumigatus (9.37%. Out of 40 cases, 35 (87.5% were observed as neutropenic. Eight medicinal plants (A. tenuifolius, A. racemosus, B. aegyptiaca, E. alba, M. koenigii, P. murex R. communis and T. foenum graecum showed significant antimicrobial activity (P P. aeruginosa was observed highest susceptible bacteria (46.6% on the basis of susceptible index. Conclusion It can be concluded that treated oral cancer patients were neutropenic and prone to secondary infection of microbes. The medicinal plant can prove as effective antimicrobial agent to check the secondary infections in treated cancer patients.

The case study approach  

OpenAIRE

Abstract The case study approach allows in-depth, multi-faceted explorations of complex issues in their real-life settings. The value of the case study approach is well recognised in the fields of business, law and policy, but somewhat less so in health services research. Based on our experiences of conducting several health-related case studies, we reflect on the different types of case study design, the specific research questions this approach can help answer, the data sources th...

Meta-analysis of genome-wide association studies identifies ten loci influencing allergic sensitization.  

Science.gov (United States)

Allergen-specific immunoglobulin E (present in allergic sensitization) has a central role in the pathogenesis of allergic disease. We performed the first large-scale genome-wide association study (GWAS) of allergic sensitization in 5,789 affected individuals and 10,056 controls and followed up the top SNP at each of 26 loci in 6,114 affected individuals and 9,920 controls. We increased the number of susceptibility loci with genome-wide significant association with allergic sensitization from three to ten, including SNPs in or near TLR6, C11orf30, STAT6, SLC25A46, HLA-DQB1, IL1RL1, LPP, MYC, IL2 and HLA-B. All the top SNPs were associated with allergic symptoms in an independent study. Risk-associated variants at these ten loci were estimated to account for at least 25% of allergic sensitization and allergic rhinitis. Understanding the molecular mechanisms underlying these associations may provide new insights into the etiology of allergic disease. PMID:23817571

Study of the tolerance of ten accessions of carrot (Daucus carota L. to salinity  

Directory of Open Access Journals (Sweden)

Full Text Available The present work has focused on the assessment of the tolerance of ten accessions of carrot (L1, L2, L3, F4, E5, R7, R8, L10, G11 and S12 to salt stress, grown in the region of Sidi Bouzid. The tests were carried out under plastic greenhouse (during 5 months. The results obtained show that the salt stress reduced the parameters of growth and production. However, a difference in the response to salt stress was recorded between the accessions studied. A reduction in yield of up to 70 % with the concentration 3 g / l of NaCl, for different accessions studied is recorded. However, the accession L1 who has given the longer roots and dry matter yield and the largest root shows the most tolerant accessions unlike L10, G11 and S12 which are the most sensitive.

Karyological studies in ten species of Citrus (Linnaeus, 1753 (Rutaceae of North-East India  

Directory of Open Access Journals (Sweden)

Full Text Available Ten Citrus (Linnaeus, 1753 species of North-East India have been karyo-morphologically analysed. All studied species had 2n=18 chromosomes without any evidence of numerical variation. All the chromosomes were found to be of metacentric and sub-metacentric in all the species; the morphology of the chromosomes showing size difference only. Symmetrical karyotype which does not have much difference in the ratio of longest to shortest chromosome in all the species was observed. Three species, C. grandis (Osbeck, 1757, C. reticulata (Blanco, 1837 and C. medica (Linnaeus, 1753 are identified as true basic species from asymmetry studies of karyotypes as they reflect on the primitive nature of their genomes. C. indica (Tanaka, 1937 occupies a special taxonomic position within the genus Citrus as a progenitor for other cultivated species

Hydroxyapatite ceramic-coated femoral stems in young patients. A prospective ten-year study.  

Science.gov (United States)

We describe the clinical and radiological results of 38 total hip replacements (THR) using the JRI Furlong hydroxyapatite-ceramic (HAC)-coated femoral component in patients younger than 50 years. The mean age at the time of operation was 42 years (22 to 49) and the mean length of follow-up was ten years (63 to 170 months). All patients receiving a Furlong HAC THR were entered into the study regardless of the primary pathology including patients who had undergone previous hip surgery. The mean Harris hip score improved from 44 before operation to 92 at the last post-operative review. After 12 years the cumulative surivival for the stem was 100% (95% confidence interval 89 to 100). No femoral component was revised. Our results show that the Furlong HAC implant gives excellent long-term results in young patients with high demands. PMID:15568523

Use of illicit stimulant drugs in Finland: a wastewater study in ten major cities.  

Science.gov (United States)

Estimations of drug use at the national level are generally based on various sources of information, such as drug seizures, socio-scientific studies, toxicological data and hospital records. Nevertheless, all of these approaches have limitations that cannot be overcome, even if conclusions are drawn from combined data retrieved from different sources. Drug epidemiology through wastewater analysis has the potential to provide unique perspectives, internationally comparable data, and up-to-date information on the use of both traditional illicit drugs and new psychoactive substances (NPSs). In Finland, no large-scale studies on regional illicit drug consumption, based on a wastewater approach, have been reported. In this study, 24-h influent composite samples were collected during two 1-week study periods from ten different wastewater treatment plants in May and November-December 2012. The cities included in the study represent the geographical areas throughout Finland and cover 40% of the Finnish population. The samples were analyzed with an in-house validated, ultra high-performance liquid-chromatography mass spectrometric (UHPLC-MS/MS) method for various common illicit drugs and some NPS type stimulant drugs. The results were also compared with available statistics, information on drug seizures and laboratory-confirmed toxicological data, as well as other studies available based on wastewater analysis. The data show that illicit stimulant drug use is more common in the larger cities of Southern Finland. Amphetamine was the most commonly used drug in all 10 cities during both collection periods (excluding the collection period in May in Lappeenranta). Cocaine consumption remains very low in Finland in comparison to other European countries; it was concentrated in the biggest cities in Southern Finland. This study shows interesting temporal and spatial differences in drug use in Finland, as well as the possibilities of using wastewater analytics to reveal local hotspots of NPS consumption.

A Ten Year Descriptive Study of Adult Leukaemia at Al-Jomhori Teaching Hospital in Sana'a, Yemen  

Directory of Open Access Journals (Sweden)

Full Text Available Background: There is scarcity of data of the epidemiology of leukaemia in Arab countries including Yemen. Understanding patterns of leukaemia underpins epidemiology and can provide insight into disease etiology. The aim of this research is to determine the epidemiologic pattern of adult leukaemia in Yemen. Methods: The research is a descriptive cross-sectional study. We analyzed the data of 702 adult patients with leukaemia, who were newly diagnosed over a ten-year period between October 1999 and October 2009 at the referral haematology centre in Sana’a at Al-Jomhori Teaching Hospital, according to type of leukaemia, age, sex, geographic distribution and time of diagnosis. Results: Acute Myeloid Leukaemia (AML was found to be the most common (45.1% followed by Chronic Myeloid Leukaemia (CML (26.5%, Acute Lymphoid Leukaemia (ALL (17.7% and Chronic Lymphoid Leukaemia (CLL (10.7%, respectively. There was an almost equal prevalence of AML and CML for males and females but males had significantly more cases of ALL and CLL (p =0.008. A significant variation in geographic pattern showed that the highest number of cases is seen the Central mountainous region and the least number of cases in the South-eastern region which is coastal and lowland (p<0.001. The seasonal variation showed that higher number of ALL cases was seen in the summer months (33% compared with other seasons (21% in the spring, 24.2% in autumn and 21.8% in winter. Conclusions: The pattern of adult leukaemia in Yemen is different from that seen in western countries which could be attributed to different environmental exposure. The geographic pattern indicates a possible role of certain environmental factors which warrant further investigations. The pattern of seasonal variation needs further studies for evaluating the seasonality.

Prehospital trauma care reduces mortality. Ten-year results from a time-cohort and trauma audit study in Iraq  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Blunt implementation of Western trauma system models is not feasible in low-resource communities with long prehospital transit times. The aims of the study were to evaluate to which extent a low-cost prehospital trauma system reduces trauma deaths where prehospital transit times are long, and to identify specific life support interventions that contributed to survival. Methods In the study period from 1997 to 2006, 2,788 patients injured by land mines, war, and traffic accidents were managed by a chain-of-survival trauma system where non-graduate paramedics were the key care providers. The study was conducted with a time-period cohort design. Results 37% of the study patients had serious injuries with Injury Severity Score ? 9. The mean prehospital transport time was 2.5 hours (95% CI 1.9 - 3.2. During the ten-year study period trauma mortality was reduced from 17% (95% CI 15 -19 to 4% (95% CI 3.5 - 5, survival especially improving in major trauma victims. In most patients with airway problems, in chest injured, and in patients with external hemorrhage, simple life support measures were sufficient to improve physiological severity indicators. Conclusion In case of long prehospital transit times simple life support measures by paramedics and lay first responders reduce trauma mortality in major injuries. Delegating life-saving skills to paramedics and lay people is a key factor for efficient prehospital trauma systems in low-resource communities.

Tumor del cuerpo carotídeo: A propósito de 10 casos tratados / Carotid body tumors: Report of ten cases  

Scientific Electronic Library Online (English)

Full Text Available SciELO Chile | Language: Spanish Abstract in spanish [...] Abstract in english Background: Carotid body tumors arise from a cellular conglomerate located at the carotid bifurcation. Progressive enlargement can involve the arterial wall and neighbor cranial nerves. Aim: To report a series of 10 patients treated of carotid body tumors and review national experience. Patients and [...] methods: Between 1984 and 2006, we operated 8 women and 2 men, aged 19 to 75 years, with this type of tumor. Results: The most common cause for consultation was a cervical mass in 90%, with a mean evolution lapse of 13.2 months (range 3 to 126). In all cases, diagnosis was confirmed with angiographic imaging and histopathology. Ten tumors were surgically removed with no complications. Eighty percent of tumors were in stage II according to Shamblin classification. During long term follow up all patients have remained asymptomatic. Only 31 carotid body tumors have been reported in Chilean medical literature during a 43 year period. Conclusions: Paragangliomas of the carotid body can be diagnosed in clinical grounds, requiring vascular imaging. These infrequent lesions are generally benign, early surgical removal by surgeons with vascular expertise avoids neurological and or vascular complications

Neutron therapy of low grade 'pencil' gliomas of the spinal cord: A review of ten cases  

Energy Technology Data Exchange (ETDEWEB)

Between 1980 and 1986 ten patients (two males, eight females, median age: 35 years) with spongioblastomas and ependymomas grade I of the spinal cord were treated with fast neutrons from the d(14)+Be reaction after incomplete tumour surgery. Eight patients received three weekly fractions of 0.7 to 1.33 Gy and two patients four weekly fractions of 0.8 Gy to total doses of 7.4 to 10.4 Gy. Two complete and six partial remissions of ataxia and motor disturbances were observed. Bladder dysfunctions in five patients cleared up partially in three cases. In two patients the symptomatology remained unchanged. After a follow-up of eight to 88 months two initially complete and two out of six partial remission were maintained. No severe late effects of the skin have been determined. In summary it is concluded that for incompletely resected 'pencil'-gliomas fast neutrons therapy seems to be a feasible treatment modality.

Role of nanocrystalline silver dressings in the management of toxic epidermal necrolysis (TEN) and TEN/Stevens-Johnson syndrome overlap.  

Science.gov (United States)

Toxic epidermal necrolysis (TEN) and Stevens-Johnson syndrome (SJS) are severe mucocutaneous eruptions. There is currently no defined optimal approach to wound care. The objective of this study was to evaluate silver dressings in the wound-care management of TEN and SJS/TEN syndrome overlap with a retrospective case review of nine patients with TEN and SJS/TEN overlap presenting to our institution. Nanocrystalline silver dressings appear to be useful in the rapid commencement of healing in these patients. TEN and SJS/TEN overlap are rare conditions. This contributed to a relatively small number of cases included in the study. The ease of application, antimicrobial properties and low frequency of change make nanocrystalline silver dressings ideal in TEN/SJS. PMID:25368980

The Result of The Treatment of Infantile Spasm After Two Year Follow-Up Review Of 45 Cases in Ten Past Years  

Directory of Open Access Journals (Sweden)

Full Text Available In the past ten years, 45 cases of infantile spasm treated in our center. From these patients, 15 cases received only steroid, other 15 cases only clonazepam, and the rest, a combination of clonazepam and steroid. All patients were observed for two years. This is a retrospective study, the data being extracted from patients record. A number of patients were treated in ambulatory and the others were patients of the hospital. The result of comparison of optimal control of seizures are as follow: 1 In only steroid group 27 percent of the patients were free of seizure, 2 In only clonazepam group 28 percent showed no seizure, 3 in combined clonazepam and steroid group 39% were seizure-free. Based on this trial we believe that treatment of infantile spasm with combined steroid and clonazepam is better than any of them alone. Considering these results, we believe that the treatment of infantile spasm with a combination of steroid and clonazepam is preferable to these drugs.

Tetanus in a rural setting of South-Western Nigeria: a ten-year retrospective study.  

Science.gov (United States)

We review the records of 79 tetanus patients in two hospitals (one tertiary and one secondary level) in Owo, Ondo state, Nigeria from 1997 to 2006. The male: female ratio was 3:1. Ages were 14-70 years (mean 33.25 years, SD ±16.76). The overall case fatality rate (CFR), 32.91%, did was not significantly different in the two hospitals. CFR for men was 32.10% and for women 35.29%. The main factor indicative of bad prognosis was a short hospitalization period. It was observed that 30.38% of our patients were discharged against medical advice (DAMA), that financial constraint was the underlying problem in 50% of cases, and that the trend of DAMA occurred at the two study sites. This DAMA phenomenon could pose a great danger to the eradication of this vaccine preventable disease in rural areas. PMID:21483514

Consequences from use of reminiscence - a randomised intervention study in ten Danish nursing homes  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Reminiscence is the systematic use of memories and recollections to strengthen self-identity and self-worth. The study aim was to investigate the consequences for nursing home residents and staff of integrating reminiscence into daily nursing care. Methods In this randomised study, ten nursing homes were matched into two groups on the basis of location, type and size. In the period August 2006 - August 2007, staff in the Intervention Group were trained and supported in the use of reminiscence, involving individual and group sessions with residents as well as reminiscence boxes, posters and exhibitions. At baseline and again 6 and 12 months after the intervention start, data were collected on residents' cognitive level, agitated behaviour, general functioning and proxy-assessed quality of life, as well as on staff well-being and job satisfaction. Mixed linear modelling was used to analyse differences in outcome between the intervention and control groups. Results Project drop-out rates were 32% for residents and 38% for nursing staff. Most staff in the Intervention Group considered reminiscence a useful tool that improved their communication with residents, and that they would recommend to other nursing homes. There were no significant differences between residents in the Intervention and the Control Group in cognitive level, agitated behaviour or general functioning. Residents in the Intervention Group showed significant higher score at 6 months in quality of life subscale 'Response to surroundings', but there was no significant difference at 12 months. Positive effects of reminiscence were observed for all staff outcome measures, the only exception being SF-12 self-rated physical health. At 6 months after start of reminiscence, staff in the Intervention Group had significantly better scores than those in the Control Group for Personal accomplishment, Emotional exhaustion, Depersonalisation, 'Attitude towards individual contact with residents' and SF-12 self-rated mental health. At 12 months after start of reminiscence, staff in the Intervention Group had significantly better scores than those in the Control Group for Emotional exhaustion and 'Professional role and development'. Conclusions The use of reminiscence appeared to have little long-term effect on the nursing home residents. Nursing staff in the Intervention Group experienced greater satisfaction with professional roles and developed a more positive view of the residents.

Ten-year study on varieties of parotid tumors in pediatrics  

International Nuclear Information System (INIS)

Parotid tumors are uncommon because they account for 0.5 % of all types of cancer in pediatrics. They generally occur as increased local asymptomatic volume, occasionally accompanied by pain and inflammatory signs. A retrospective, longitudinal and descriptive study was carried out to determine the frequency and forms of presentation of parotid tumors diagnosed in 0-18 years-old patients, who had been admitted to the oncological surgery service of 'William Soler' pediatric hospital from February 2001 to December 2010. The variables taken into account were sex, forms of presentation, response to treatment as well as the histological variants presented, with the objective of giving information about these variants of parotid tumors in pediatrics, which, despite their rareness, represent a high risk group when occur. Seven patients were diagnosed, of whom 3 were pleomorphic adenomas, one adenocarcinoma, one mucoepidermoid carcinoma of the gland, one parotid Hodgkin lymphoma and one mixed tumor with atypical cells of the gland. The onset of all the tumors was the presence of a parotid mass in 6 asymptomatic cases and in one case suffering local pain. They were all performed gland ultrasound and aspiration fine needle biopsy. Males prevailed over the females (ratio of 5:2) and the average age of presentation was 12.3 years. Surgery is the main therapeutic weapon in most of cases. It was recommended to closely follow the patients because of their high rate of local recurrence

Equity in HIV testing: evidence from a cross-sectional study in ten Southern African countries  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background HIV testing with counseling is an integral component of most national HIV and AIDS prevention strategies in southern Africa. Equity in testing implies that people at higher risk for HIV such as women; those who do not use condoms consistently; those with multiple partners; those who have suffered gender based violence; and those who are unable to implement prevention choices (the choice-disabled are tested and can have access to treatment. Methods We conducted a household survey of 24,069 people in nationally stratified random samples of communities in Botswana, Lesotho, Malawi, Mozambique, Namibia, South Africa, Swaziland, Tanzania, Zambia, and Zimbabwe. We asked about testing for HIV in the last 12 months, intention to test, and about HIV risk behaviour, socioeconomic indicators, access to information, and attitudes related to stigma. Results Across the ten countries, seven out of every ten people said they planned to have an HIV test but the actual proportion tested in the last 12 months varied from 24% in Mozambique to 64% in Botswana. Generally, people at higher risk of HIV were not more likely to have been tested in the last year than those at lower risk, although women were more likely than men to have been tested in six of the ten countries. In Swaziland, those who experienced partner violence were more likely to test, but in Botswana those who were choice-disabled for condom use were less likely to be tested. The two most consistent factors associated with HIV testing across the countries were having heard about HIV/AIDS from a clinic or health centre, and having talked to someone about HIV and AIDS. Conclusions HIV testing programmes need to encourage people at higher risk of HIV to get tested, particularly those who do not interact regularly with the health system. Service providers need to recognise that some people are not able to implement HIV preventive actions and may not feel empowered to get themselves tested.

Early detection, early symptom progression and symptomatic remission after ten years in a first episode of psychosis study  

DEFF Research Database (Denmark)

Background: Poor symptom outcome remains a challenge in psychosis: At least 50% of first-episode patients continue to have positive and/or negative symptoms after ten years. Objective: To investigate rates, early predictors and early symptom progression of long-term non-remitted psychosis in an early detection study. Methods: Symptomatic remission according to new international criteria was assessed in 174 patients at ten-year follow-up. Remitted and non-remitted patients were compared on early symptom progression, and logistic regression was applied to predict non-remission. Results: At ten years, 50% of patients were in symptomatic remission. Non-remission was predicted by positive symptoms at inclusion and during the first year of treatment. Of individual symptoms only hallucinations were significantly predictive of ten-year non-remission. Early symptom differences were not reflected by differences in treatment. Conclusions: Long-term symptomatic non-remission is associated with early positive symptoms. More assertive intervention may be needed in patients who do not respond robustly in the first year of treatment, whether or not they have been detected “early”.

Henoch-Schönlein purpura outcome in children: A ten-year clinical study  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction. Henoch-Schönlein purpura (HSP is the most common vasculitis of childhood. It is characterized by symptoms including nonthrombocytopenic purpura, abdominal pain, haematuria/proteinuria, and arthralgia/arthritis. The pleiomorphism of clinical signs in HSP could be confused with other conditions or other vasculitis forms. Objective. Evaluation of HSP clinical presentation, the onset and severity of renal manifestation in affected children and their outcome. Methods. A retrospective study of 49 patients diagnosed with HSP was conducted from September 1999 to September 2009. Children with severe renal manifestations (nephrotic range proteinuria, with or without nephrotic or nephritic syndrome have undergone kidney biopsy. Results. Twenty-five patients developed renal manifestations after onset of the disease. In our study child’s older age was a risk factor for association with HSP nephritis. Six of the patients required kidney biopsy. They were successfully treated with various immunosuppressive protocols, as well as three of nine patients with nephrotic range proteinuria. Two patients developed most severe form of HSP nephritis, nephrotic-nephritic syndrome with histology grade IIIb/IVb. During the study period (average follow-up 6 years, all patients had a normal global renal function with mild proteinuria in only two cases. The prognosis of renal involvement was better than reports from other patient series. Conclusion. Long-term morbidity of HSP is predominantly attributed to renal involvement. During the study period, no patient had renal insufficiency or end stage renal disease after various combinations of immunosuppressive treatment. It is recommended that patients with HSP nephritis are followed for longer periods of time with a regular measurement of renal function and proteinuria.

Case study of isosurface extraction algorithm performance  

Energy Technology Data Exchange (ETDEWEB)

Isosurface extraction is an important and useful visualization method. Over the past ten years, the field has seen numerous isosurface techniques published leaving the user in a quandary about which one should be used. Some papers have published complexity analysis of the techniques yet empirical evidence comparing different methods is lacking. This case study presents a comparative study of several representative isosurface extraction algorithms. It reports and analyzes empirical measurements of execution times and memory behavior for each algorithm. The results show that asymptotically optimal techniques may not be the best choice when implemented on modern computer architectures.

Study on dose distributions in a slab phantom irradiated by several tens MeV neutrons  

International Nuclear Information System (INIS)

From the viewpoint of radiation protection for high and intermediate energy radiation fields such as accelerator facilities, it is important to evaluate the effective dose due to secondary neutrons produced. As for the effective dose evaluation, the accuracy of high energy particle transport code system, however, has not been validated experimentally for intermediate energy neutrons. To establish a method of effective dose evaluation due to several tens MeV neutrons, neutron fluxes and dose distributions in a slab phantom were measured with SSNTDs (Solid State Nuclear Track Detectors), fission counter, TEPC and TEIC using 40- and 65-MeV quasi-monoenergetic neutrons at TIARA of JAERI. The measured distributions were compared with the calculated ones with the HETC-3STEP and MORSE-CG codes. In addition, for the purpose of applying them to the dose evaluation, the energy spectra of source neutrons and energy responses of detectors were determined. As a result, the calculated distributions of neutron flux and absorbed dose within the phantom were in good agreement with the experimental ones, and those of dose equivalent agreed with the measured ones within about 20%. It was found that the effective dose for several tens MeV neutrons could be evaluated with the accuracy of about ±20%. Source spectra below 10 MeV were evaluated from the present measurements and calculations. The evaluated ones will be very useful for future experiments and calculations in TIARA because they have not been measured. The energy responses of SSNTDs were evaluated for neutrons of wide energy range, based on the newly developed computation code and the measured responses for neutrons ranging from 100 keV to 65 MeV.

Triacylglycerols in some underutilised tropical seed oils 1. Systematic studies of ten oils  

International Nuclear Information System (INIS)

Triacylglycerols composition of ten lesser known and underutilised tropical seed oils have been determined. The seed oils include Monodora tenuifolia, Monodora myristica, Colocynthis citrullus, Cyperus esculentus, Cucumeropsis edulis, Andenopus breviflorus, Telfairia occidentalis, Blighia sapida, Antiaris africana and Sesame indicum. In the Moreaceae family (M. tenuifolia, M. myristica) the dominant triacylglycerol are OPO/POO, LLO, OOL, and OOO. They accounted for over 60% of the total triacylglycerol content in the oils. In the Cyperaceae family (C. esculentus), OPP/POO, POL and OOO accounted for over 80% of the total triacylglycerol content. In the Cucurbitaceae family, SSP was the dominant triacylglycerol specie in A. breviflorus, while OPO/POO and OOO were the dominant species in C. citrullus and C. edulis. Blighia sapida recorded a different distribution of triacylglycerols composition. PLL occurred at the highest concentration, while other high molecular weight triacylglycerols were also identified in the oil. They include, SSA, OSA, LSA, OAA and LLA. Analysis of A. antiaris oil showed a different pattern in the distribution of the triacylglycerols. LaLaM, MMLa and LaLaLa accounted for about 80% of the total triacylglycerols. This result reflected the fatty acid composition of the oil. Lauric acid (C12:0) and Myristic acid (C14:0) accounted for 71.5% of the total fatty acid. The possible use of the oils as cocoa butter equivalents CBEs and cocoa butter substitutes CBSs are discussed. (author)

Case Study: The Business End of Cases  

Science.gov (United States)

This article takes a retrospective look at how the folks in business schools look at the case method. The legacy of cases in business may seem short in the eyes of some but it is positively ancient when compared to the use of the case study in the sciences, which began to take hold in the 1990s. Surprisingly, in spite of its impeccable academic pedigree, there seems to be little literature on the success of the method; virtually no assessment data in business, law, or public policy teaching seems to exist.

FMCT verification: Case studies  

International Nuclear Information System (INIS)

Full text: How to manage the trade-off between the need for transparency and the concern about the disclosure of sensitive information would be a key issue during the negotiations of FMCT verification provision. This paper will explore the general concerns on FMCT verification; and demonstrate what verification measures might be applied to those reprocessing and enrichment plants. A primary goal of an FMCT will be to have the five declared nuclear weapon states and the three that operate unsafeguarded nuclear facilities become parties. One focus in negotiating the FMCT will be verification. Appropriate verification measures should be applied in each case. Most importantly, FMCT verification would focus, in the first instance, on these states' fissile material production facilities. After the FMCT enters into force, all these facilities should be declared. Some would continue operating to produce civil nuclear power or to produce fissile material for non- explosive military uses. The verification measures necessary for these operating facilities would be essentially IAEA safeguards, as currently being applied to non-nuclear weapon states under the NPT. However, some production facilities would be declared and shut down. Thus, one important task of the FMCT verifications will be to confirm the status of these closed facilities. As case studies, this paper will focus on the verification of those shutdown facilities. The FMCT verification system for former military facilities would have to differ in some ways from traditional IAEA safeguards. For example, there could be concerns about the potential loss of sensitive information at these facilities or at collocated facilities. Eventually, some safeguards measures such as environmental sampling might be seen as too intrusive. Thus, effective but less intrusive verification measures may be needed. Some sensitive nuclear facilities would be subject for the first time to international inspections, which could raise concerns for states that have traditionally had 'less transparency' in their military sectors. As case studies, first we investigate how to applied verification measures including remote sensing, off-site environmental sampling and on-site inspections to monitor the shutdown status of plutonium production facilities, and what measures could be taken to prevent the disclosure of sensitive information at the site. We find the most effective verification measure to monitor the status of the reprocessing plant would be on-site environmental sampling. Some countries may worry that sample analysis could disclose sensitive information about their past plutonium production activities. However, we find that sample analysis at the reprocessing site need not reveal such information. Sampling would not reveal such information as long as inspectors are not able to measure total quantities of Cs-137 and Sr-90 from HLW produced at former military plutonium production facilities. Secondly, we consider verification measures for shutdown gaseous diffusion uranium-enrichment plants (GDPs). The GDPs could be monitored effectively by satellite imagery, as one telltale operational signature of the GDP would be the water-vapor plume coming from the cooling tower, which should be easy to detect with satellite images. Furthermore, the hot roof of the enrichment building could be detectable using satellite thermal-infrared images. Finally, some on-site verification measures should be allowed, such as visual observation, surveillance and tamper-indicating seals. Finally, FMCT verification regime would have to be designed to detect undeclared fissile material production activities and facilities. These verification measures could include something like special or challenge inspections or complementary access. There would need to be provisions to prevent the abuse of such inspections, especially at sensitive and non-proscribed military and nuclear activities. In particular, to protect sensitive information, it is essential to have an appropriate managed access mechanism, which should be able to re

An overview of Fortis Ontario, formerly the Canadian Niagara Power Company Ltd. was presented along with details of its distribution businesses, assets and Newfoundland-based parent company, including operating companies and utility operating companies. Recent distribution investments and acquisitions were reviewed. An outline of facts concerning Ontario's distribution sector was presented with details of fragmentation, local distribution company (LDC) consultation procedures and transfer taxes. A case study of Port Colborne Hydro was provided, with an outline of operational synergy implementations including improved flexibility of existing staff; harmonization of labour contracts; a reduction in equipment and fleet costs; and centralization of stores and local customer service centres. An account of back-office efficiencies introduced at Port Colborne was presented, including an information technology (IT) system; accounting and billing modifications; new regulatory and tax efficiency measures; and a guaranteed cash flow for the municipality. Details concerning the purchase of Cornwall Electric were presented along with details of several operational synergies implemented after the purchase such as work sharing between regional operations; consolidation of equipment and fleet cost; a reduction of some positions; a local customer service centre; and separate labour unions and contracts. New corporate synergies included: an IT system; accounting and billing; regulatory and human resources modifications; and safety and environmental modifications. Cost savings results for 2003 were presented, with $870, 000 in captured savings and $1,343, 000 in sustained annual savings. A chart of reduced operating costs per customer was also provided. It was concluded that in order to integrate acquisitions, it was essential to establish a task force prior to closing and implement a new organization structure as quickly as possible. A regional approach to operation and service delivery was recommended, as well as an emphasis on reducing cost and not service levels. Success required a common culture and standards, with rigorous attention to details, discipline and controllable costs, as well as full accountability. tabs., figs.

A Review of Ten Years of the Study for Monitoring Antimicrobial Resistance Trends (SMART from 2002 to 2011  

Directory of Open Access Journals (Sweden)

Full Text Available Surveillance of antimicrobial agent resistance provides important information to guide microbiologists and infectious disease specialists understanding of the control and the spread of resistance mechanisms within the local environment. Continued monitoring of antimicrobial resistance patterns in the community and in local hospital environments is essential to guide effective empiric therapy. The Study for Monitoring Antimicrobial Resistance Trends (SMART has monitored the in vitro susceptibility patterns of clinical Gram-negative bacilli to antimicrobial agents collected worldwide from intra-abdominal infections since 2002 and urinary tract infections since 2009. Resistance trends, with a particular focus on carbapenem resistance and the rate of extended-spectrum ?-lactamases (ESBLs, were analyzed. Isolates from intra-abdominal infections (n = 92,086 and urinary-tract infections (n = 24,705 were collected and tested using Clinical and Laboratory Standards Institute methods. This review presents carbapenem susceptibility and ESBL rates over ten years of SMART study analysis, including key publications during this period. The SMART study has proved to be a valuable resource in determining pathogen prevalence and antibiotic susceptibility over the last ten years and continues to provide evidence for regulatory susceptibility breakpoints and clinical decision making.

Bacteriological profile of community acquired acute bacterial meningitis: A ten-year retrospective study in a tertiary neurocare centre in South India  

Directory of Open Access Journals (Sweden)

Full Text Available Purpose: Ten years retrospective study to evaluate the bacteriological spectrum of community acquired acute bacterial meningitis (CAABM. Methods: Cerebrospinal fluid (CSF samples from 385 clinically suspected cases of pyogenic meningitis were processed for cell counts, cytospin Gram stain, culture, antigen detection by latex agglutination (LAT and antibiotic susceptibility test. Eighteen of these CSF samples were also subjected to a polymerase chain reaction (PCR assay for detection of pneumococcal DNA. Results: The etiological agent could be identified in 284 (73.8% of the total 385 cases by culture and/or smear and /or LAT. Streptococcus pneumoniae was the predominant pathogen accounting for 238 (61.8% cases. Haemophilus influenzae and Neisseria meningitidis accounted for 7 (1.8% and 4 (1% cases respectively. Other gram negative bacilli, Streptococcus spp. and Staphylococcus aureus were isolated from 19 (4.9%, 9 (2.3% and 7 (1.8% cases respectively. Conclusions: Streptococcus pneumoniae remains the major aetiological agent of CAABM both in adults and children in our set-up. No penicillin resistance was detected among the isolates. Further research should focus on preventable aspects of CAABM, especially pneumococcal vaccines, to help reduce the disease burden.

Congenital anomalies among live births in a polluted area. A ten-year retrospective study  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Congenital anomalies and their primary prevention are a crucial public health issue. This work aimed to estimate the prevalence of congenital anomalies in Brindisi, a city in southeastern Italy at high risk of environmental crisis. Methods This research concerned newborns up to 28 days of age, born between 2001 and 2010 to mothers resident in Brindisi and discharged with a diagnosis of congenital anomaly. We classified cases according to the coding system adopted by the European Network for the Surveillance of Congenital Anomalies (EUROCAT. Prevalence rates of congenital anomalies in Brindisi were compared with those reported by EUROCAT. Logistic regression models were adapted to evaluate the association between congenital anomalies and municipality of residence of the mother during pregnancy. Results Out of 8,503 newborns we recorded 194 subjects with congenital anomalies (228.2/10,000 total births, 1.2 times higher than the one reported by the EUROCAT pool of registries. We observed 83 subjects with congenital heart diseases with an excess of 49.1%. Odds Ratios for congenital heart diseases significantly increased for newborns to mothers resident in Brindisi (OR 1.75 CI 95% 1.30-2.35. Conclusions Our findings indicated an increased prevalence of Congenital Anomalies (especially congenital heart diseases in the city of Brindisi. More research is needed in order to analyze the role of factors potentially involved in the causation of congenital anomalies.

Effect of TENS on pain in relation to central sensitization in patients with osteoarthritis of the knee: study protocol of a randomized controlled trial  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Central sensitization has recently been documented in patients with knee osteoarthritis (OAk. So far, the presence of central sensitization has not been considered as a confounding factor in studies assessing the pain inhibitory effect of tens on osteoarthritis of the knee. The purpose of this study is to explore the pain inhibitory effect of burst tens in OAk patients and to explore the prognostic value of central sensitization on the pain inhibitory effect of tens in OAk patients. Methods Patients with knee pain due to OAk will be recruited through advertisements in local media. Temporal summation, before and after a heterotopic noxious conditioning stimulation, will be measured. In addition, pain on a numeric rating score, WOMAC subscores for pain and function and global perceived effect will be assessed. Patients will be randomly allocated to one of two treatment groups (tens, sham tens. Follow-up measurements will be scheduled after a period of 6 and 12 weeks. Discussion Tens influences pain through the electrical stimulation of low-threshold A-beta cutaneous fibers. The responsiveness of central pain-signaling neurons of centrally sensitized OAk patients may be augmented to the input of these electrical stimuli. This would encompass an adverse therapy effect of tens. To increase treatment effectiveness it might be interesting to identify a subgroup of symptomatic OAk patients, i.e., non-sensitized patients, who are likely to benefit from burst tens.

Objective To assess the cumulative 10-year incidence of diabetic retinopathy (DR) and its associated factors in a population living in Greater Beijing. Methods The population-based longitudinal Beijing Eye Study, which included 4439 subjects (age in 2001: 40+years) in 2001, was repeated in 2011 with 2695 subjects participating (66.4% of the survivors). The study participants underwent a detailed ophthalmic examination. Fundus photographs were examined for the new development of DR. Results After excluding individuals with DR at baseline (n?=?87) or no sufficient fundus photographs in 2011 (n?=?6), the study included 2602 subjects with a mean age of 64.6±9.7 years (median: 64.0 years; range: 50 to 93 years). In the 10-year period, 109 subjects (39 men) developed new DR with an incidence of 4.2% (95% confidence interval (CI): 3.45,5.03). In multiple logistic regression analysis, incident DR was significantly associated with higher HbA1c value (Phyperopia) and, potentially, higher CSFP may be additional risk factors to be taken into account when counseling and treating patients with diabetes mellitus.

Bioassessment of Alkaline Drainage from Coal Mines in Western Pennsylvania: A Ten-Year Study  

Science.gov (United States)

Abandoned coal mine drainage (AMD) impacts over 6,500 km of streams in Pennsylvania. AMD alters stream pH and dissolved ions, and often produces precipitated metals that coat stream substrates. We studied 3 streams from 1994 to 2004, before and after treatment wetlands were constructed in 1997-9 to intercept discharges with high iron (60-90 ppm) and alkalinity (100-130 mg/L CaCO3) and low manganese and aluminum. Receiving streams are circumneutral with 5-40 ppm total iron and thick iron precipitate. Annual replicate sets of Surber and D nets, rock wash, and leaf packs were sampled. Regression analysis of genus level data showed statistically significant improvement in the two second-order streams. Community profiles are now statistically similar in sites upstream and downstream from AMD. The larger third stream showed moderate AMD impacts before 1997 and no statistically significant biological trends after wetlands substantially decreased levels of AMD in all three streams. This study indicated biological recovery lagged behind chemical recovery by at least 3 years. The patterns of appearance of macroinvertebrate taxa in alkaline AMD sites indicate that commonly used tolerance indices developed for organic pollution do not predict macroinvertebrate responses to AMD. Our study can provide a basis for broader benchmarks in bioassessment of coal mine pollution.

Reproduction and production in a buffaloes farm of the Marche region: a ten-year study  

Directory of Open Access Journals (Sweden)

Full Text Available Water buffalo milk reproductive and productive traits are fundamental to evaluate farm efficiency and dairy economy. Due to the buffalo cows’ long life these aspects are also important to assess the improvement of genetic animal potential and to reach optimal productive performance. Currently this knowledge is critical since the Italian cattle population is decreasing whereas the national buffalo sector is expanding; this trend is partially depending on the reconversion of some dairy cattle’ farms into buffalo cows’ farms. The present investigation was undertaken to study non-genetic factors affecting reproductive parameters and milk production traits in a farm located in a not traditional area for buffalo farming.

Double Sequential External Defibrillation in Out-of-Hospital Refractory Ventricular Fibrillation: A Report of Ten Cases.  

Science.gov (United States)

Abstract Background. Ventricular fibrillation (VF) is considered the out-of-hospital cardiac arrest (OOHCA) rhythm with the highest likelihood of neurologically intact survival. Unfortunately, there are occasions when VF does not respond to standard defibrillatory shocks. Current American Heart Association (AHA) guidelines acknowledge that the data are insufficient in determining the optimal pad placement, waveform, or energy level that produce the best conversion rates from OOHCA with VF. Objective. To describe a technique of double sequential external defibrillation (DSED) for cases of refractory VF (RVF) during OOHCA resuscitation. Methods. A retrospective case series was performed in an urban/suburban emergency medical services (EMS) system with advanced life support care and a population of 900,000. Included were all adult OOHCAs having RVF during resuscitation efforts by EMS providers. RVF was defined as persistent VF following at least 5 unsuccessful single shocks, epinephrine administration, and a dose of antiarrhythmic medication. Once the patient was in RVF, EMS personnel applied a second set of pads and utilized a second defibrillator for single defibrillation with the new monitor/pad placement. If VF continued, EMS personnel then utilized the original and second monitor/defibrillator charged to maximum energy, and shocks were delivered from both machines simultaneously. Data were collected from electronic dispatch and patient care reports for descriptive analysis. Results. From 01/07/2008 to 12/31/2010, a total of 10 patients were treated with DSED. The median age was 76.5 (IQR: 65-82), with median resuscitation time of 51minutes (IQR: 45-62). The median number of single shocks was 6.5 (IQR: 6-11), with a median of 2 (IQR: 1-3) DSED shocks delivered. VF broke after DSED in 7 cases (70%). Only 3 patients (30%) had ROSC in the field, and none survived to discharge. Conclusion. This case series demonstrates that DSED may be a feasible technique as part of an aggressive treatment plan for RVF in the out-of-hospital setting. In this series, RVF was terminated 70% of the time, but no patient survived to discharge. Further research is needed to better understand the characteristics of and treatment strategies for RVF.

Utility of ten-second uptake periods for kinetic studies of serotonin uptake by intact platelets  

International Nuclear Information System (INIS)

When washed human platelets accumulate serotonin (5HT), it is possible with the use of formaldehyde fixative to measure uptake over periods as short as 10 seconds. To evaluate the utility of these short times for kinetic studies of 5HT uptake, we have examined the accuracy with which the 10 second uptake rate reflects changes in the extracellular 5HT concentration. The amount of 5HT taken up over a 10 second period appears to be determined by the concentration of 5HT present in the extracellular medium during that time period, and the uptake rate can change rapidly following sudden changes in the extracellular 5HT concentration. However, the extent of inhibition of 5HT uptake in the presence of imipramine of extracellular 5HT concentrations greater than 10-5M is somewhat different depending on whether the 5HT is allowed to accumulate for a 10-second or a 5- or 10-minute uptake period. A 10-second uptake period thus appears to be useful for kinetic studies of initial 5HT uptake velocities under normal conditions, but under inhibitory conditions may give results differing from those obtained with minute-long periods

A ten-year longitudinal study of intense ambivalence as a predictor of risk for psychopathology.  

Science.gov (United States)

The predictive validity of the Intense Ambivalence Scale was examined in a 10-year longitudinal study of 362 psychometrically identified psychosis-prone and control participants. Elevated scores on the Intense Ambivalence Scale predicted psychotic-like and depressive symptoms, and the development of psychotic illnesses at the 10-year follow-up assessment (after the removal of variance for membership in the psychosis-prone and control groups). Elevated scores on the scale were also associated with substance abuse, schizotypal symptoms, and impaired functioning at both the initial and follow-up assessments. The Intense Ambivalence Scale did not differentially enhance the predictive power of the Perceptual Aberration or the Magical Ideation Scales. PMID:10919697

Study of thin-film silicon solar cells at irradiances above ten thousand suns  

International Nuclear Information System (INIS)

We used a tightly focused Gaussian beam of a HeNe laser to study accelerated light-induced degradation (Staebler-Wronski effect) and high photocarrier generation rates in amorphous and microcrystalline silicon thin-film solar cells, at up to13 MW/m2 irradiance. For the experiments, the spot radius was varied from a minimum of 8.6 ?m in the focus to around 1 mm away from the focus. According to COMSOL'' (registered) simulations, even at these high power densities heat diffusion into a glass substrate aided by spreading conduction via the Ag back-contact restricts the temperature rise to less than 14 K. Short-circuit current can be measured directly over a range of irradiances, and the J-V characteristic may be estimated by taking into account shunting by the inactive part of the cell.

Trends in the theoretical and research methodological approaches applied in doctoral studies in information and knowledge management: an exploration of ten years of research in South Africa  

Directory of Open Access Journals (Sweden)

Full Text Available The past ten years have seen the field of information and knowledge management develop and implement new and improved technologies. Because of the ease with which information is exchanged the contribution to information overload has increased exponentially and the need for information and knowledge management is more real than ever before. Research in itself is a science of knowledge creation that continuously evolves in line with newly developed theories and research methodologies. An investigation of the theories and research methodologies that doctoral theses, completed in South Africa, ascribed to over the past ten years were conducted. Search strings containing 'information management', 'knowledge management' and 'information and knowledge management' were searched within citation, abstract and subject fields. A sample of 30 theses from a possible 47 in the relevant population was identified. Qualitative and mixed methods research design was favoured, making use of case studies and surveys, but paying little attention to theoretical approaches or paradigms. The boundaries between disciplines are continuously re-defined, new disciplines evolve and traditional disciplines suffer under the pressures of changing problems of the world. The importance of research in the field of information and knowledge management being grounded in the most recent scientific thought is emphasized.

Ten-Year Retrospective Longitudinal-Study of Student Perspectives on Value of REU  

Science.gov (United States)

For more than two decades, federal agencies have been enthusiastically supporting summer research experiences for undergraduates. These REU programs are tacitly intended to increase retention and provide "an important educational experience" for undergraduates, particularly women, minorities and underrepresented groups. Numerous authors (viz., Laursen, Lopatto, Dolan, among many others) have enthusiastically described positive impacts of summer REU programs from exit interview data. These results include enhanced persistence to pursue STEM careers and confirmed desire to attend graduate school in the field targeted by a particular REU. Perhaps surprisingly, negative student experiences are rarely described in the scholarly literature, but do appear in more informal publications (viz., Gueterma, 2007). One wonders how REU alumni, looking back over their entire collective portfolio of experiences, now perceive the educational value of their REU experience relative to their other educational experiences. To obtain a backwards-looking, reflective description from REU alumni on the value of their REU experiences, we conducted a 10-year, two-stage study was designed to explore the ways in which the REU acted as an educational experience for 51 women from a single geoscience sub-discipline. The first phase was an ex post facto longitudinal analysis of data, including multiple interviews with each participant during their REU, annual open-ended alumni surveys, faculty interviews, and extensive field notes, over a 10-year period. This analysis informed the second phase, a clinical interview. Over 10 hours of interviews with 8 participants were conducted and analyzed. These 8 participants were selected to represent a variety of career stages, and for their potential to reflect on a wide variety of educational experiences. Results from the interviews, done many years after their REU experience, indicate that the interviewees' REU did not provide a substantive educational experience related to the nature of scientific work, the scientific process, or the culture of academia when considered in a comparative context of students' other educational experiences. Results further indicated that the REU did not serve to transform participants' conceptions about themselves as situated in science, and learning gains with regard to other aspects of the self, were somewhat limited. Instead, the data suggests that these women arrived at the REU with pre-existing and remarkably strong conceptions in these areas, and that the REU did not functional to alter those states. These conceptions were frequently the result of interactions with mentors/scientists from middle school until well into the undergraduate period.

Immunohistochemical studies on uterine carcinosarcoma, leiomyosarcoma, and endometrial stromal sarcoma: expression and prognostic importance of ten different markers.  

Science.gov (United States)

Uterine sarcomas are rare and aggressive gynecologic malignancies. In this immunohistochemical (IHC) study, expression of Ki-67, p53, CD10, CD44, desmin, smooth muscle actin, estrogen receptor ? (ER?), androgen receptor (AR), progesterone receptor A (PRA), and c-kit and their influence on survival in cases of uterine carcinosarcoma (CS), leiomyosarcoma (LMS), and endometrial stromal sarcoma (ESS) were evaluated. Medical records were reviewed and data collected concerning all uterine sarcomas treated during a 12-year period at Helsinki University Central Hospital. There was sufficient histological material for IHC analysis and slide review in 67 cases. Survival analysis was performed using the Kaplan-Meier method, and median survival times with 95% confidence intervals are given. Survival in cases of LMS was statistically significantly affected by the expression of p53, ER?, and PRA. Striking differences in expression of IHC markers when comparing results with those in earlier studies were the absence of AR immunoreactivity in all uterine sarcomas and low incidence of c-kit (15%; in endometrial stromal sarcoma). None of the markers was statistically significantly associated with survival of ESS and CS patients. The expression of p53, ER?, and PRA in uterine LMS may give prognostic information concerning the behavior of the disease. Hormonal therapy could be recommended as a treatment option in cases of hormone receptor-positive LMS. PMID:21161468

In the first case study, 6 municipalities participated in a pilot program designed to compare the performance of biodiesel and diesel fuels. Each municipality operated 2 base vehicles running on conventional diesel along with 2 similar vehicles which used biodiesel. Real time emissions tests and analyses of the vehicles using biodiesel were also conducted by 2 of the participating municipalities. All municipalities participating in the study agreed to purchase significant volumes of biodiesel. The second case study described a pilot study conducted by the City of Vancouver's equipment services branch in 2004. As a result of the study, the city now has over 530 types of equipment that use biodiesel. The third case study described a program designed by TSI Terminals in Vancouver to assess the emission reduction impact of using biodiesel at its port facility. Six different pieces of equipment were used to confirm that biodiesel could be used throughout the terminal. Test results confirmed that biodiesel blends could be used to reduce emissions. Overall emissions were reduced by 30 per cent. The fourth case study described a waste renderer that used a fleet of 36 trucks to deliver raw products to its plants. The company made the decision to use only biodiesel for its entire fleet of trucks. Since July 2005, the company has logged over 1.7 mly 2005, the company has logged over 1.7 million km using biodiesel blends. The fifth case study described a salmon hatchery that switched from diesel to biodiesel in order to reduce emissions. The biodiesel blends are used to fuel the hatchery's 2 diesel generators. The hatchery has reduced emissions of greenhouse gases (GHGs) by an estimated 1800 tonnes annually. The sixth case study described how the Township of Langley has started using biodiesel for its entire fleet of of approximately 250 pieces of equipment. The township has not encountered any operational differences in their field operations since switching to biodiesel. 26 figs

Os Trigonum Syndrome: A Case Study  

Directory of Open Access Journals (Sweden)

Full Text Available Os trigonum syndrome is one of the rare causes of posterior foot pain. Ostrigonum, which is placed at the posterior of talus, is an accessory bone. Ostrigonum syndrome causes back foot pain due to compression between talusand calcaneus. In this study, we present a case of os trigonum syndrome ,which is a rare disease and is generally missed. A 65-year-old female patientwith a complaint of left foot pain for the last 2 months persented to our outpatientclinic. In the physical examination, plantar flexion of the ankle andtoe was painful. Patient’s pain was evaluated by the visual analog scale andnoted as 8 cm. There was sensitivity at the posterior of talus during palpation.Os trigonum syndrome was diagnosed based on radiological examinationsand a physical therapy program consisting of transcutaneous electrical nervestimulation (TENS, cold pack, foot and ankle range of motion and strengtheningexercises was started. After the treatment, pain VAS decreased to 2cm,and then the patient was followed clinically. As in our case, os trigonum syndromeshould also be taken into consideration in patients complaining withposterior foot pain apart from other frequently encountered causes. In suchcases, physical therapy programs are very effective in pain management andin reducing the cost of treatment. Turk J Phys Med Rehab 2013;59:161-4.

Powers of Ten  

Science.gov (United States)

"Powers of Ten", the film made by Charles and Ray Eames in 1977, takes the viewer from the core of an atom to the edge of the universe, moving 10 times further every 10 seconds. The film is about scale and how we view the universe and our place in it. Powers of Ten is an extremely valuable tool for teaching and understanding our world through the concept of scale. Although math is the most obvious field of study, it can be applied to every subject matter. In the same way that a knowledge of geography allows us to comprehend locations and their relative distance, a knowledge of scale gives us the perspective to see all things in terms of relative size. It gives us a sense of place in the universe and expands our thinking in non-linear ways. When I first saw this film in 1977 it made a huge impression on me. it drives home the concepts of scientific notation in a very engaging way. With today's focus on micro- and nanotechnologies, the cencepts of scale, which this video reinforces, are very important.You can view the video right on the web site or purchase a dvd. There are a number of related educational resources that are also available.

Experimental study of a fast plasma focus discharge operated in the range of tens of joules emitting neutrons  

International Nuclear Information System (INIS)

In this doctoral research, a small plasma focus discharge operated at tens of joules and kilo amperes has been experimentally studied. This device produces a coaxial discharge by an electrode arrange which consists of an inner electrode, a cylindrical insulator, and an outer electrode. The discharge is driven by a capacitive generator and it is operated at pressures of some millibars. Typical electrical parameters of the device are T/4?150ns, 160 nF, 40 nH, 30-100J, 40-70kA. When Deuterium is used as filling gas, neutrons are produced by fusion reactions. The device, namely PF-50J, is one of the most extreme plasma focus reported in the literature to emit neutrons. The results of this work have demonstrated that the same dynamics found in larger machines (operated from kJ to MJ) is also found in this extremely low energy device which means that after the discharge is initiated, a plasma sheet is formed over the insulator. By the action of the Lorentz force, the plasma sheet moves axially. When the sheet reaches the top end of the inner electrode, it starts to implode radially to finally form a dense plasma column (pinch). Finally, the plasma column is disrupted 5-10ns after column formation. Shock piston velocities of the order of 104-105m/s were estimated from experiments for each discharge dynamical phase. Typical pinch densities of 1024-25m-3 were also observed in PF-50J. An interesting feature observed in this work is esting feature observed in this work is the formation of axial jet-like structures which appears at late times almost hundred nanoseconds after pinch disruption. These structures are composed by a metallic plasma which results from ablation of the inner electrode. The mechanism responsible for the formation of this kind of structure is still unknown, although evidence suggests that the phenomena is not related to the pinch formation process. One of the principal motivations of this thesis was to study the optimization for neutron emission in the PF-50J device. This plasma focus is expected to yield 103-104 neutrons per pulse when is operated with deuterium. Standard detection techniques, for example neutron activation detectors, present detection limits higher than 105 neutrons per pulse, so it was necessary to develop a measurement method for higher efficiency detectors based on the use moderated proportional counter tubes for the purpose of neutron optimization. In contrast to low rate continuous regime, this detectors show pulse piling up when irradiated with pulsed neutrons, which make impossible to count events with standard nuclear electronics. In this thesis, it is presented a detailed study of pulsed piling up statistics in the proportional counter and a complete characterization of the 3He tubes based detection system. Regarding that the net area of detector output signal is proportional to the number of detected events, a counting model was developed and thus a methodology for measurement of the neutron yield is proposed. Special emphasis was put on the sources of fluctuation that affects the measurement process, which are given by the counting statistics, piling up statistics, and background electrical noise. As a result, the methodology allows measurements uncertainties for pulsed D-D fusion neutrons lower than 30% in the range of Y ? 3x103n/shot, reducing in this way by almost two order of magnitude the detection limit of the state of art techniques. A theoretical study of the detection frequency or reproducibility for pulsed neutron sources is also presented. Comparisons with results in PF-50J show that theoretical models for reproducibility are reasonable high boundary estimations for the experimental values. The optimization study is presented in the last part of this work. Optimal conditions for neutron emission were experimentally obtained. An interesting finding is the observation of two regimes for pinch formation and neutron emission. The first regime is related to the pinch formation close to the first current maximum in the first quarter of period, while in the second one thes

Effects of tripolar TENS of vertebral column on slow and fast motor units: A preliminary study using H-reflex recovery curve method  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: Effect of tripolar TENS of vertebral column on slow and fast motoneurons (MNs activity of soleus muscle was previously investigated. In this study for better differentiation of the behavior of slow and fast MNs, we exploited H-reflex recovery curve recording in two muscles of soleus and lateral gastrocnemius, respectively as the representatives of slow and fast muscles. Methods: 10 healthy non-athlete women aged 22.7±2.21 years participated in two (control and test sessions. H-reflex recovery curve of soleus (slow and gastrocnemius (fast muscles were recorded before and 15 minutes after applying tripolar TENS (TENS frequency= 100 Hz and pulse width= 300 ?s on vertebral column. For recording the curve, rectangular paired stimuli were applied on tibial nerve (ISI= 40-520, frequency= 0.2 Hz, pulse width= 600 ?s. Results: Our findings showed that maximum H-reflex recovery in gastrocnemius muscle appeared in shorter ISIs (240 ms, while in soleus muscle it appeared in longer ISIs (400 ms. H-reflex recovery curve amplitude slightly decreased after applying tripolar TENS. The comparison of H-reflex recovery curve of both soleus and gastrocnemius muscles either in control or test session did not show any significant difference (P>0.05. Conclusion: It is suggested that tripolar TENS excites not only the skin but also Ia and Ib afferents in the dorsal column. Synaptic interactions of these afferents in spinal cord cause the inhibition of type I MNs and facilitation of type II MNs.

Auditory and visual health after ten years of exposure to metal-on-metal hip prostheses: a cross-sectional study follow up.  

Science.gov (United States)

Case reports of patients with mal-functioning metal-on-metal hip replacement (MoMHR) prostheses suggest an association of elevated circulating metal levels with visual and auditory dysfunction. However, it is unknown if this is a cumulative exposure effect and the impact of prolonged low level exposure, relevant to the majority of patients with a well-functioning prosthesis, has not been studied. Twenty four male patients with a well-functioning MoMHR and an age and time since surgery matched group of 24 male patients with conventional total hip arthroplasty (THA) underwent clinical and electrophysiological assessment of their visual and auditory health at a mean of ten years after surgery. Median circulating cobalt and chromium concentrations were higher in patients after MoMHR versus those with THA (P0.05). Objective assessments, including amplitude and signal-to-noise ratio of transient evoked and distortion product oto-acoustic emissions (TEOAE and DPOAE, respectively), were similar for all the frequencies tested (P>0.05). Auditory brainstem responses (ABR) and cortical evoked response audiometry (ACR) were also similar between groups (P>0.05). Ophthalmological evaluations, including self-reported visual function by visual functioning questionnaire, as well as binocular low contrast visual acuity and colour vision were similar between groups (P>0.05). Retinal nerve fibre layer thickness and macular volume measured by optical coherence tomography were also similar between groups (P>0.05). In the presence of moderately elevated metal levels associated with well-functioning implants, MoMHR exposure does not associate with clinically demonstrable visual or auditory dysfunction.

Probabilistic consequence study of residual radiological effects from a hypothetical ten-ton inadvertent nuclear yield. Weapons Safety Program  

International Nuclear Information System (INIS)

In this paper we study the potential radiological consequences of a strategic bomber accident, in which one of the assumed on-board nuclear weapons explodes with an arbitrarily chosen 10-ton nuclear yield. The frequency of such an occurrence is infinitesimal. The safety design features in today s nuclear weapons' systems essentially forbid its occurrence. We have a chosen a military base which has the feature of being a representative combination of urban and rural populations. The assumed ''crash site'' is near the northwest comer of the military base, close to civilian housing located just across the street from the base. A worst case wind would be from the ESE (east south east). This would cause fission debris to be dispersed toward the largest population centers and, thus, would lead to the largest Pu ''collective'' doses (i.e., a dose integrated over time and summed over individuals). Also, if an ESE wind were blowing at accident time, some people in nearby housing could receive lethal gamma-ray doses from fallout before evacuation could occur. It is assumed only one weapon undergoes nuclear yield; the other on-board weapons would HE detonate and the Pu would be aerosolized and lofted. We assume an activity-size distribution and lofting similar to those used to predict fallout measured at NTS. The main thrust of our study is to provide estimates of probabilistic radiological risks to the population local to a strategic bomber crash site. The studied radiological consequences are: cloud-passage doses from Pu inhalation; doses from groundshine due to gamma-producing radionuclides; and areal contamination from Pu and the long-lived fission products Cs-137 and Sr-90

Endometriosis-associated ovarian cancer: A ten-year cohort study of women living in the Estrie Region of Quebec, Canada  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Objectives Endometriosis has been believed to increase the risk of developing ovarian cancer, but recent data supporting this hypothesis are lacking. The aim of this study was to verify whether the incidence of endometriosis, ovarian cancer and the both increased during the last 10 years among women living in the Estrie region of Quebec. Methods We collected data of women diagnosed with endometriosis, ovarian cancer or both, between 1997 and 2006, from a population living in the Estrie region of Quebec. We performed this retrospective cross-sectional study from the CIRESSS (Centre Informatisé de Recherche Évaluative en Services et Soins de Santé system, the database of the CHUS (Centre Hospitalier Universitaire of Sherbrooke, Sherbrooke, Canada. Results Among the 2854 identified patients, 2521 had endometriosis, 292 patients had ovarian cancer and 41 patients had both ovarian cancer and endometriosis. We showed a constant increase in the number of ovarian cancer (OC between 1997 and 2006 (r2 = 0.557, P = 0.013, which is not the case for endometriosis (ENDO or endometriosis-associated ovarian cancer (EAOC. The mean age ± SD was 40.0 ± 9.9 and 53.9 ± 11.4 for patients having ENDO and OC, respectively. Mean age of women with EAOC was 48.3 ± 10.8, suggesting an early onset of ovarian cancer in women having endometriosis of about 5.5 years average, P = 0.003. Women with ENDO were at increased risk for developing OC (Rate Ratio [RR] = 1.6; 95% Confidence Interval [CI] = 1.12-2.09. Pathological analyses showed the predominance of endometrioid type (24.4% and clear-cell type (21.9% types in EAOC compared to OC, P = 0.0070 and 0.0029, respectively. However, the serous type is the most widespread in OC (44.5% in comparison to EAOC (19.51%, P = 0.0023. Conclusion Our findings highlight that the number of cases of ovarian cancer is constantly increasing in the last ten years and that endometriosis represents a serious risk factor which accelerates its apparition by about 5.5 years.

Solar Olympic village case study  

Energy Technology Data Exchange (ETDEWEB)

The Sydney 2000 Olympic Games incorporates an athlete's village which is part of a larger new residential development called Newington, aimed at creating a practical example of more sustainable living for the 21st century. Newington has a range of environmental features including solar hot water, solar photovoltaics, energy efficient design and water recycling for irrigation and toilets. Each home will have 1 kW (peak) of roof integrated PV connected to the grid via an inverter system. This paper presents a case study of the management, design, installation and testing of the solar village PV systems and also discusses related policy issues and requirements. The Newington development demonstrates that using today's technology a high concentration of solar power may be readily integrated into a residential development with benefits to all participants. However, work is needed to allow sustainable options to be made available to the mainstream market. (author)

Mieloses funiculares considerações a propósito de 110 casos / Subacute combined degeneration of the spinal cord: an analysis of one hundred and ten cases  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese O autor, revendo o conceito atual da etiopatogenia das mieloses funiculares, conclui que, na determinação do processo desmielinizante, além da carência de vitamina B12 e da acloridria gástrica, participam outros fatores, carenciais e/ou alérgicos. Baseado no estudo de 110 casos com lesões gástricas [...] constitucionais (100 casos) ou adquiridas (10 casos), o autor discute o problema do diagnóstico. São consideradas as síndromes periférica, funicular dorsal, "piramidal" e encefálica. É ressaltada a importância do exame da sensibilidade vibratória, particularmente por método quantitativo, que revelou, em elevada percentagem dos casos, distúrbios da palestesia também nas mãos. Entre os exames complementares, é salientado o valor do hemograma, do mielograma, da dosagem da acidez gástrica, da determinação da absorção da vitamina B12 radioativa; são também consideradas as alterações electrencefalográficas e do liqüido cefalorraqueano. Os resultados terapêuticos em 44 casos são avaliados através do estudo semiquantitativo da sintomatologia neurológica. Embora a vitamina B12 tenha proporcionado maiores índices de melhora, os demais medicamentos (extrato hepático, ácido fólico e adrenocorticotropina) também influenciaram favoravelmente o quadro neurológico. Em vista da pequena representação numérica da casuística nos grupos correspondentes aos quatro esquemas terapêuticos, o autor não emite conclusão definitiva. Salienta, porém, que êsses resultados demonstram a necessidade de prosseguir nos estudos sôbre a etiopatogenia das mieloses funiculares, no sentido de esclarecer as numerosas incógnitas que ainda perduram. Abstract in english After a review on the present concept of the etiopathogenesis of funicular myelosis (subacute combined degeneration of the spinal cord) the author states the conclusion that in the causation of the demyelinating process, besides the lack of vitamin B]2 and gastric achlorhydria, other deficiency or a [...] llergic factors take part. Based on the study of 110 cases with constitutional (100 cases) or acquired (10 cases) gastric lesions, the author discusses the problem of the diagnosis. Peripheral, dorsal funicular, "pyramidal", and encephalic syndromes are considered. The importance of the examination of the vibration sense, particularly by quantitative methods, is emphasized; in a great percentage of cases, disturbances of this sensation were also disclosed in the upper limbs. Among the laboratory findings, the value of blood count, bone-marrow smear, gastric acidity analysis, and the study of absorption of radioactive vitamin B12 is stressed. Changes in the electroencephalogram and cerebrospinal fluid are also considered. Therapeutic results in 44 cases are estimated by the semi-quantitative study of the neurological signs. Although vitamin B12 displayed higher degree of improvement, the other drugs (liver extract, folic acid and adreno-corticotropin) have also influenced favorably the neurological manifestations. Owing to the low numerical representation of cases in the groups corresponding to the four schemes of treatment, the author does not state a definite conclusion. But he emphasizes that these results demonstrate the need of further studies on the etiopathogenesis of funicular myelosis, in an attempt to settle the several questions still unsolved.

Temporal patterns in count-to-ten fetal movement charts and their associations with pregnancy characteristics: a prospective cohort study  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Fetal movement counting has long been suggested as a screening tool to identify impaired placental function. However, quantitative limits for decreased fetal movement perform poorly for screening purposes, indicating the need for methodological refinement. We aimed to identify the main individual temporal patterns in fetal movement counting charts, and explore their associations with pregnancy characteristics. Methods In a population-based prospective cohort in Norway, 2009–2011, women with singleton pregnancies counted fetal movements daily from pregnancy week 24 until delivery using a modified "count-to-ten” procedure. To account for intra-woman correlation of observations, we used functional data analysis and corresponding functional principal component analysis to identify the main individual temporal patterns in fetal movement count data. The temporal patterns are described by continuous functional principal component (FPC curves, with an individual score on each FPC for each woman. These scores were later used as outcome variables in multivariable linear regression analyses, with pregnancy characteristics as explanatory variables. Results Fetal movement charts from 1086 pregnancies were included. Three FPC curves explained almost 99% of the variation in the temporal data, with the first FPC, representing the individual overall counting time, accounting for 91% alone. There were several statistically significant associations between the FPCs and various pregnancy characteristics. However, the effects were small and of limited clinical value. Conclusions This statistical approach for analyzing fetal movement counting data successfully captured clinically meaningful individual temporal patterns and how these patterns vary between women. Maternal body mass index, gestational age and placental site explained little of the variation in the temporal fetal movement counting patterns. Thus, a perceived decrease in fetal movement should not be attributed to a woman’s basic pregnancy characteristics, but assessed as a potential marker of risk.

Concentrated photovoltaics, a case study  

Science.gov (United States)

Concentrated Photovoltaics (CPV), once a niche technology, has now reached the maturity and reliability for large scale power generation. Especially in regions where temperatures are very high, the use of high efficiency triple junction solar cells with concentrating optics allows stable energy yield. Thus CPV can be seen as complementary and not in concurrence with silicon photovoltaics. The state of the art, the advantages and limitations of this technology will be shown. Among the main advantages of CPV is the possibility of a much higher energy supply, when compared to silicon photovoltaics, both comparing CPV and silicon with same area or the same installed power. The use of recycled and recyclable materials allows a more environmentally friendly production. The possibility to couple CPV with desalination facilities, energy storage will be analysed. As an example a case study of a CPV installation in Northern Italy is discussed. Here the use of mature technologies, derived from automotive and lighting sectors resulted in a simple and efficient module.

Energy-motivation case study  

Energy Technology Data Exchange (ETDEWEB)

Most energy-management case studies focus on capital investments in new technical equipment, such as more-efficient boilers, lighting systems or computerised energy-management systems. The wide range of technical options for saving energy are well documented and advertised. Another aspect of energy management - namely the achievement of 'no cost' or 'good housekeeping' measures through well-organised motivation and incentive campaigns - is not so well reported. This is due to there being few examples of this type of project, which itself probably reflects the energy managers' preferences for dealing with 'hard' engineering rather than 'soft' people-orientated issues. This paper documents the development and implementation of a motivation campaign for the Social Services Department of Coventy City Council which was novel for two reasons: first, it is believed to be the first motivation campaign in a Social Services department; and secondly, it involved the use of training, incentives and feedback in an integrated way that it is believed greatly boosted its effectiveness.

The 'fine structure' of nutrient dynamics in rivers: ten years of study using high-frequency monitoring  

Science.gov (United States)

A complete appraisal of material fluxes in flowing waters is really only possibly with high time resolution data synchronous with measurements of discharge. Defined by Kirchner et al. (2004; Hydrological Processes, 18/7) as the high-frequency wave of the future and with regard to disentangling signal noise from process pattern, this challenge has been met in terms of nutrient flux monitoring by automated bankside analysis. In Ireland over a ten-year period, time-series nutrient data collected on a sub-hourly basis in rivers have been used to distinguish fluxes from different catchment sources and pathways and to provide more certain temporal pictures of flux for the comparative definition of catchment nutrient dynamics. In catchments where nutrient fluxes are particularly high and exhibit a mix of extreme diffuse and point source influences, high time resolution data analysis indicates that there are no satisfactory statistical proxies for seasonal or annual flux predictions that use coarse datasets. Or at least exposes the limits of statistical approaches to catchment scale and hydrological response. This has profound implications for catchment monitoring programmes that rely on modelled relationships. However, using high resolution monitoring for long term assessments of catchment mitigation measures comes with further challenges. Sustaining continuous wet chemistry analysis at river stations is resource intensive in terms of capital, maintenance and quality assurance. Furthermore, big data capture requires investment in data management systems and analysis. These two institutional challenges are magnified when considering the extended time period required to identify the influences of land-based nutrient control measures on water based systems. Separating the 'climate signal' from the 'source signal' in river nutrient flux data is a major analysis challenge; more so when tackled with anything but higher resolution data. Nevertheless, there is scope to lower costs in bankside analysis through technology development, and the scientific advantages of these data are clear and exciting. When integrating its use with policy appraisal, it must be made clear that the advances in river process understanding from high resolution monitoring data capture come as a package with the ability to make more informed decisions through an investment in better information.

Disaster exposure as a risk factor for mental health problems, eighteen months, four and ten years post-disaster – a longitudinal study  

Science.gov (United States)

Background Disaster experiences have been associated with higher prevalence rates of (mental) health problems. The objective of this study was to examine the independent relation between a series of single disaster experiences versus the independent predictive value of a accumulation of disaster experiences, i.e. a sum score of experiences and symptoms of distress and post-traumatic stress disorder (PTSD). Methods Survivors of a fireworks disaster participated in a longitudinal study and completed a questionnaire three weeks (wave 1), eighteen months (wave 2) and four years post-disaster (wave 3). Ten years post-disaster (wave 4) the respondents consisted of native Dutch survivors only. Main outcome measures were general distress and symptoms of PTSD. Results Degree of disaster exposure (sum score) and some disaster-related experiences (such as house destroyed, injured, confusion) were related to distress at waves 2 and 3. This relation was mediated by distress at an earlier point in time. None of the individual disaster-related experiences was independently related to symptoms of distress. The association between the degree of disaster exposure and symptoms of PTSD at waves 2 and 3 was still statistically significant after controlling for symptoms of distress and PTSD at earlier point in time. The variable ‘house destroyed’ was the only factor that was independently related to symptoms of PTSD at wave 2. Ten years after the disaster, disaster exposure was mediated by symptoms of PTSD at waves 2 and 3. Disaster exposure was not independently related to symptoms of PTSD ten years post-disaster. Conclusions Until 4 years after the disaster, degree of exposure (a sum score) was a risk factor for PTSD symptoms while none of the individual disaster experiences could be identified as an independent risk factor. Ten years post-disaster, disaster exposure was no longer an independent risk factor for symptoms of PTSD. Since symptoms of PTSD and distress at earlier waves perpetuate the symptoms at later waves, health care workers should aim their resources at those who still have symptoms after one and a half year post-disaster, to prevent health problems at medium and long-term.

A comparison of hip guidance with reciprocating gait orthoses in children with spinal paraplegia: results of a ten-year prospective study.  

Science.gov (United States)

Twenty-two children with spinal paraplegia were entered into a prospective randomised study to assess the efficacy of two reciprocating orthoses and to identify any prognostic factors that might affect continuing use of the devices. Thirteen received a hip guidance orthosis (HGO) and nine a reciprocating gait orthosis (RGO). They were followed for a mean of ten years. At one year follow-up there were three statistically significant differences between the two groups at the 5% level: repairs were commoner in the RGO group, the RGO group improved in their ability to walk over difficult outdoor surfaces and the HGO group improved more in their ability to rise from a sitting to standing position. At one year follow-up there was a positive parental and child's view of the benefits of the orthoses, but by ten years only 24% of the patients were still using the orthoses. We were not able to show any definite advantage of one device over the other or any statistically significant prognostic factors for walking in the longer term with a reciprocating orthosis. We question whether or not the routine provision of these types of orthosis is justifiable when it appears that, in the longer term, the patients we studied preferred wheelchair mobility.

Powers of ten  

CERN Multimedia

Powers of Ten is a 1977 short documentary film written and directed by Charles Eames and his wife, Ray. The film depicts the relative scale of the Universe in factors of ten (see also logarithmic scale and order of magnitude). The film begins with an aerial image of a man reclining on a blanket; the view is that of one meter across. The viewpoint, accompanied by expository voiceover, then slowly zooms out to a view ten meters across ( or 101 m in standard form), revealing that the man is picnicking in a park with a female companion. The zoom-out continues, to a view of 100 meters (102 m), then 1 kilometer (103 m), and so on, increasing the perspectiveâ??the picnic is revealed to be taking place near Soldier Field on Chicago's waterfrontâ??and continuing to zoom out to a field of view of 1024 meters, or the size of the observable universe. The camera then zooms back in to the picnic, and then to views of negative powers of tenâ??10-1 m (10 centimeters), and so forth, until we are viewing a carbon nucl...

Waves and turbulences studies in plasmas: ten years of research on quiescent plasmas at the Brazilian Space Research National Institute  

International Nuclear Information System (INIS)

Quiescent plasmas generated by thermionic discharges and surface confined by multipole magnetic fields have been used in basic plasma research since 1973. The first machine was developed at UCLA (USA) to produce an uniform plasma for beam and waves studies in large cross section plasmas. A double quiescent plasma machine was constructed at the plasma laboratory of INPE in 1981, it began its operation producing linear ion-acoustic waves in an Argon plasma. Later on non linear ion acoustic waves and solitons were studied in plasma containing several species of negative and positive ions. The anomalous particle transport across multipole magnetic fields were also investigated. An anomalous resistivity associated with an ion acoustic turbulence is responsible for the formation of a small amplitude double-layer. The existence of a bootstrap mechanism is shown experimentally. Today, the main interest is toward the generation of Langmuir waves in non uniform plasmas. An experimental study on Langmuir wave generation using a grid system is been carried on. A magnetized quiescent plasma device for studies of whistle wave generation is been constructed. This machine will make possible future studies on several wave modes of magnetized plasmas.

Roadmaster Roading Contractors Case Study  

Directory of Open Access Journals (Sweden)

Full Text Available Systems analysis students seldom experience the practical difficulties of the initial investigation into a client?s requirements. They get little chance to practice the skills they need to investigate complex and confused problem situations, or to appreciate the wider organizational issues that can impact on a situation. This teaching case is designed to give students the opportunity to practice and apply investigation skills and to challenge them to consider the wider work environment when considering possible solutions to a problem situation. The case is conducted as a role-play, with students acting as systems analysts and teaching staff role-playing the clients. The students develop a report analyzing the client?s situation based on the issues that arise during the interviews. Feed-back sessions focus on discussing how well the students applied various interviewing strategies previously covered in lectures, and on the wider organizational problems that could impact proposed information system solutions.

Trends of Tuberculosis Case Notification and Treatment Outcomes in the Sidama Zone, Southern Ethiopia: Ten-Year Retrospective Trend Analysis in Urban-Rural Settings  

Science.gov (United States)

Background Ethiopia is one of the high tuberculosis (TB) burden countries. An analysis of trends and differentials in case notifications and treatment outcomes of TB may help improve our understanding of the performance of TB control services. Methods A retrospective trend analysis of TB cases was conducted in the Sidama Zone in southern Ethiopia. We registered all TB cases diagnosed and treated during 2003–2012 from all health facilities in the Sidama Zone, and analysed trends of TB case notification rates and treatment outcomes. Results The smear positive (PTB+) case notification rate (CNR) increased from 55 (95% CI 52.5–58.4) to 111 (95% CI 107.4–114.4) per 105 people. The CNRs of PTB+ in people older than 45 years increased by fourfold, while the mortality of cases during treatment declined from 11% to 3% for smear negative (PTB-) (X2trend, P<0.001) and from 5% to 2% for PTB+ (X2trend, P<0.001). The treatment success was higher in rural areas (AOR 1.11; CI 95%: 1.03–1.2), less for PTB- (AOR 0.86; CI 95%: 0.80–0.92) and higher for extra-pulmonary TB (AOR 1.10; CI 95%: 1.02–1.19) compared to PTB+. A higher lost-to-follow up was observed in men (AOR 1.15; CI 95%: 1.06–1.24) and among PTB- cases (AOR 1.14; CI 95%: 1.03–1.25). More deaths occurred in PTB-cases (AOR 1.65; 95% CI: 1.44–1.90) and among cases older than 65 years (AOR 3.86; CI 95%: 2.94–5.10). Lastly, retreatment cases had a higher mortality than new cases (6% vs 3%). Conclusion Over the past decade TB CNRs and treatment outcomes improved, whereas the disparities of disease burden by gender and place of residence reduced and mortality declined. Strategies should be devised to address higher risk groups for poor treatment outcomes. PMID:25460363

Ten years of progress—improved hysterectomy outcomes in Finland 1996–2006: a longitudinal observation study  

Science.gov (United States)

Objectives To study the outcome of various hysterectomies in 2?years 1996 (N =10110) and 2006 (N=5279). The hypothesis was that the change in operative practices in 10?years has resulted in improvements. Design 2 prospective nationwide cohort evaluations with the same questionnaire. Setting All national operative hospitals in Finland. Participants Patients scheduled to either abdominal hysterectomy (AH), vaginal hysterectomy (VH) or laparoscopic hysterectomy (LH) for benign disease. Outcome measures Patients’ characteristics, surgery-related details and complications (organ injury, infection, venous thromboembolism and haemorrhage). Results The overall complication rates fell in LH and markedly in VH (from 22.2% to 11.7%, p<0.001). The overall surgery-related infectious morbidity decreased in all groups and significantly in VH (from 12.3% to 5.2%, p<0.001) and AH (from 9.9% to 7.7%, p<0.05). The incidence of bowel lesions in VH sank from 0.5% to 0.1% and of ureter lesions in LH from 1.1% to 0.3%. In 2006 there were no deaths compared with three in 1996. Conclusions The rate of postoperative complications fell markedly in the decade from 1996 to 2006. This parallels with the recommendation of the recent meta-analyses by Cochrane collaboration; the order of preference of hysterectomies was for the first time precisely followed in this nationwide study. Trial registration The 2006 study was registered in the Clinical Trials of Protocol Registration System Data (NCT00744172). PMID:24165027

Ten-year absolute risk of osteoporotic fractures according to BMD T score at menopause: the Danish Osteoporosis Prevention Study  

DEFF Research Database (Denmark)

In the non-HRT arms of the DOPS study, 10-year fracture risk was higher at each level of T score than predicted by the Kanis algorithm. Under-reporting of fractures in registers and inclusion of HRT users are probable explanations for inappropriately low fracture risk estimates for younger women. INTRODUCTION: International recommendations highlight the importance of absolute fracture risk in establishing intervention thresholds. The available estimates of long-term risk have been derived by combining relative risks from meta-analyses with U.S. normative BMD data and Swedish fracture incidence records. We validated the 2001 Kanis risk algorithm using incident fractures observed in untreated women in the first 10 years of the Danish Osteoporosis Prevention Study (DOPS). Comparisons were also made with the relative risks derived from a recent meta-analysis of 12 cohort studies. MATERIALS AND METHODS: We analyzed DXA of the spine and hip from 872 women who were enrolled in the non-hormone replacement therapy (HRT) arms of the study and had not received HRT, bisphosphonates, or raloxifene. We collected verified reports of fractures at each visit. We focused on fractures of the hip, spine, shoulder, and forearm to provide risks comparable with the Kanis algorithm. Accordingly, asymptomatic radiographic vertebral fractures were not included. RESULTS: Seventy-eight women (9%) sustained relevant fractures. The risk of fracture increased by 1.32 (95% CI, 1.02; 1.70) for each unit decrease in femoral neck T score and by 1.30 (95% CI, 1.06; 1.58) for each unit decrease in lumbar spine T score at baseline. Absolute fracture risk was higher than expected from the Kanis algorithm at all T score levels. The difference was greatest for participants in the higher range of T scores. At T = -1, the observed risk was 10.9% as opposed to an expected risk of 5.7%. Relative risk gradients were similar to those of the recent meta-analysis. CONCLUSIONS: In healthy women, examined in the first year or two after menopause, 10-year fracture risk was higher at each level of BMD T score than expected from the model by Kanis et al. Inclusion of HRT users in the cohorts used may have led to higher BMD values and lower absolute fracture risk in the Kanis model. These longitudinal data can be used directly in estimating absolute fracture risk in untreated north European women from BMD at menopause.

The association of microalbuminuria with mortality in patients with acute myocardial infarction. A ten-year follow-up study  

DEFF Research Database (Denmark)

Our study evaluates the long-term effect of microalbuminuria on mortality among patients with acute myocardial infarction. We followed 151 patients from 1996 to 2007 to investigate if microalbuminuria is a risk factor in coronary heart disease. All patients admitted with acute myocardial infarction in 1996 were included. At baseline, we recorded urinary albumin/creatinine concentration ratio, body mass index, blood pressure, left ventricle ejection fraction by echocardiography, smoking status, medication, diabetes, age, and gender. Deaths were traced in 2007 by means of the Danish Personal Identification Register. Microalbuminuria, defined as a urinary albumin/creatinine concentration ratio above 0.65 mg/mmoL, occurred in 50% of the patients and was associated with increased all-cause mortality. Thus, 68% of the patients with microalbuminuria versus 48% of the patients without microalbuminuria had died during the 10 years of follow-up (P=0.04). The crude hazard ratio for death associated with microalbuminuriawas 1.78 (CI: 1.18-2.68) (P=0.006), whereas the gender- and age-adjusted hazard ratio was 1.71 (CI: 1.03-2.83) (P=0.04). We concluded that microalbuminuria in hospitalized patients with acute myocardial infarction is prognostic for increased long-term mortality. We recommend measurement of microalbuminuria to be included as a baseline risk factor in patients with acute myocardial infarction and in future trials in patients with coronary heart disease.

Case studies in conservation science  

Science.gov (United States)

The research presented in this dissertation covers three separate topics of conservation as defined by the National Science Foundation: 1) Materials Stabilization, Strengthening, Monitoring, and Repair; 2. Understanding Material Degradation and Aging; and 3) Materials and Structural Characterization of Cultural Heritage Objects (the 'technical study'). The first topic is addressed through a study to assess the consolidant tetraethoxysilane for the stabilization of alum treated wood. Falling under materials degradation studies is a study published in American Museum Novitates to understand how environmental conditions affect the aging of fossil resins from five different deposits. Two separate studies are included in technical study of cultural heritage objects which comprises the third research area of materials characterization. The first is a survey of red dyes used in Chinese paintings from the Ming Dynasty to the Early Republic (1364-1911). The second is a study of the pigments, dyes and binders used in Hawaiian barkcloth (kapa) from the 19th century.

Recovery potential of a western lowland gorilla population following a major Ebola outbreak: results from a ten year study.  

Science.gov (United States)

Investigating the recovery capacity of wildlife populations following demographic crashes is of great interest to ecologists and conservationists. Opportunities to study these aspects are rare due to the difficulty of monitoring populations both before and after a demographic crash. Ebola outbreaks in central Africa have killed up to 95% of the individuals in affected western lowland gorilla (Gorilla gorilla gorilla) populations. Assessing whether and how fast affected populations recover is essential for the conservation of this critically endangered taxon. The gorilla population visiting Lokoué forest clearing, Odzala-Kokoua National Park, Republic of the Congo, has been monitored before, two years after and six years after Ebola affected it in 2004. This allowed us to describe Ebola's short-term and long-term impacts on the structure of the population. The size of the population, which included around 380 gorillas before the Ebola outbreak, dropped to less than 40 individuals after the outbreak. It then remained stable for six years after the outbreak. However, the demographic structure of this small population has significantly changed. Although several solitary males have disappeared, the immigration of adult females, the formation of new breeding groups, and several birth events suggest that the population is showing potential to recover. During the outbreak, surviving adult and subadult females joined old solitary silverbacks. Those females were subsequently observed joining young silverbacks, forming new breeding groups where they later gave birth. Interestingly, some females were observed joining silverbacks that were unlikely to have sired their infant, but no infanticide was observed. The consequences of the Ebola outbreak on the population structure were different two years and six years after the outbreak. Therefore, our results could be used as demographic indicators to detect and date outbreaks that have happened in other, non-monitored gorilla populations. PMID:22649511

Five case studies of multifamily weatherization programs  

Energy Technology Data Exchange (ETDEWEB)

The multifamily case studies that are the subject of this report were conducted to provide a better understanding of the approach taken by program operators in weatherizing large buildings. Because of significant variations in building construction and energy systems across the country, five states were selected based on their high level of multifamily weatherization. This report summarizes findings from case studies conducted by multifamily weatherization operations in five cities. The case studies were conducted between January and November 1994. Each of the case studies involved extensive interviews with the staff of weatherization subgrantees conducting multifamily weatherization, the inspection of 4 to 12 buildings weatherized between 1991 and 1993, and the analysis of savings and costs. The case studies focused on innovative techniques which appear to work well.

Energy savings from operation and maintenance training for apartment boiler heating systems. An energy study on ten low-income apartments  

Energy Technology Data Exchange (ETDEWEB)

The Portland Energy Office provided operation and maintenance (O&M) training to the operators of boiler heating systems for ten low-income apartment complexes in the Fall of 1990. This study tracked energy usage before and after O&M training to see if savings occurred. Training was provided on both weatherized and non-weatherized apartments to find out if weatherization impacted the amount of O&M savings to be obtained. Also, energy savings from the O&M training and building shell weatherization are compared. The O&M training averaged about four hours per building. Content was adjusted at each site to match needs of the boiler and operator. The Energy Office also provided a boiler tune-up by a service technician. The training stressed low-cost and no-cost measures which operators could either do themselves or hire service help to implement. It also emphasized boiler safety. Nine of the ten apartment complexes in the study used less energy per heating degree-day after the O&M help. Average savings were 10%. Four apartments chosen randomly as controls had negative savings; they used slightly more energy during the same post-O&M time frame. Weatherized and unweatherized apartments showed similar savings after the O&M help, 10% and 11% percent respectively. Savings from weatherization of six of the apartments in the winter of 1988--1989 were also measured. A low average of only 4% was observed, reflecting negative savings in two buildings.

A study on heparin in complex with L1 protein of ten high risk Human Papillomavirus: new structural insights based on in silico analysis  

Directory of Open Access Journals (Sweden)

Full Text Available Human papillomavirus (HPV is one of the most common causes of sexually transmitted diseases in both men and women around the world. It has been suggested that the heparan sulfate constitute the main receptor recognized by HPV, however its role during the interactions with other HPV is not very clear. BC, DE, EF, FG, and HI are the five loops displayed on the surface of the pentamer which can interact with heparin as an analogue for heparan sulfate. In this study, the L1 late protein of ten high risks HPV (HR HPV L1 corresponding to the types 31/33/35/39/45/51/52/56/58/59 were analyzed using in silico methods by looking for insights related to HR HPV L1-loops and heparin interactions. The five loop regions (BC, DE, EF, FG and HI of the ten HR HPV L1 interact with heparin, where the interaction established between the BC-loop and heparin was found to be present in all the HR HPV L1 analyzed in this study as well as those reported in the scientist literature. Moreover it was found that lysine residues are involves in most of interactions and that the chargecharge and polar interactions are stabilizing the HR HPV L1-heparin interaction. The results obtained in this work with all the in silico methods; suggest that the heparin-binding site in the loops for all the HR HPV plays an important role during HR HPV infections, where BC-loop constitute the most required structure during the HR HPV L1-heparin interactions. The charge-charge and polar interactions are the main forces stabilizing the HR HPV L1-heparin.

Outage management: A case study  

Energy Technology Data Exchange (ETDEWEB)

Outage management issues identified from a field study conducted at a two-unit commercial pressurized water reactor (PWR), when one unit was in a refueling outage and the other unit was at full power operation, are the focus of this paper. The study was conduced as part of the US Nuclear Regulatory Commission's (NRC) organizational factors research program, and therefore the issues to be addressed are from an organizational perspective. Topics discussed refer to areas identified by the NRC as critical for safety during shutdown operations, including outage planning and control, personnel stress, and improvements in training and procedures. Specifically, issues in communication, management attention, involvement and oversight, administrative processes, organizational culture, and human resources relevant to each of the areas are highlighted by example from field data collection. Insights regarding future guidance in these areas are presented based upon additional data collection subsequent to the original study.

[Ergotamine poisoning: a case study].  

Science.gov (United States)

Ergotamine is a well known pharmacological remedy applied in neurology (treatment of vascular headache) and in obstetrics (abortive remedy, uterus atony). But today it is rarely used, because of new safer anti-migraine medicine (triptanes) which cause fewer side effects. According to obstetrical indications ergotamine is applied only in hospital treatment. For that reason, cases of intoxication by this class of drugs are rarely observed. Ergotamine causes constriction of the blood vessels through the blockade of alpha-receptors and stimulation of the serotonin-receptors on the walls of blood vessels both in the central nervous system and in peripheral circulation. Intoxication/overdose symptoms may appear on application of therapeutic dose by sensitive patients, mostly by patients with migraine headache using ergotamine preparation for relief of migraine attacks. In the Regional Centre of Clinical Toxicology, a 21-year-old patient was hospitalized. She took about 20 tablets of Cafergot (complex preparation containing 1mg ergotamine tartare and 100mg caffeine). During her stay on the ward, typical symptoms of severe poisoning were observed: nausea, severe vomiting, dizziness, decreased blood pressure without perceptible pulse, narrowing of the blood vessels in the extremities of the body (peripheral vasoconstriction) - paresthesia, digital cyanosis, refrigeration of legs, angina. Due to taking once of a great dose of the drug by the patient, violent process of intoxication, possibility of dangerous complication and also the unavailability of specific antidotes and lack of efficient methods of extracorporeal elimination of the drug, the patient was intensively controlled and symptomatic treatments according to the law of intensive therapy was applied.

Labyrinthine sequestrum: four case studies.  

Science.gov (United States)

Labyrinthine sequestrum, a rare form of labyrinthitis, is highly distinct from the more commonly encountered labyrinthitis ossificans based on its unique clinical, radiologic, and histologic characteristics. The study included 4 such patients who had undergone clinical and laboratory investigations, computed tomography (CT), and magnetic resonance imaging (MRI) assessments followed by surgical procedures and pathological evaluation. Their major symptoms were otorrhea, otalgia, tinnitus, and profound hearing loss. Imaging studies showed an osteolytic soft mass with calcified debris in the inner ear, and the bony labyrinth was eroded partly or completely by granulation mass, with loss of bony morphology. Further pathological examination was coincident with inflammatory granulation tissue with some calcification or osseous tissue. The disease process is attributed to chronic osteomyelitis due to the presence of osteonecrosis. Prompt CT and MRI examinations and optimal therapeutic management facilitate definitive diagnosis and protect against fatal complications. PMID:22467283

Linguistic Overgeneralization: A Case Study  

Directory of Open Access Journals (Sweden)

Full Text Available The current study described a single child’s language acquisition. The importance of this study resided in the circumstances and the environment in which the child lived. He came from a family in which the parents were from different countries and cultures; spoke different Arabic dialects and who lived in a country in which English is spoken. The child was in his critical period of language acquisition. He seemed to have established a unique way of communicating with people surrounding him to cope with all the linguistic varieties around him. The study showed that the child had semantic, syntactic and morphological overgeneralized structures. The data and results showed that overgeneralization and language acquisition were primarily an innate faculty of the human mind and that imitation did played a primary role in language acquisition.It showed, nevertheless, that imitation and behaviorist approaches could not fully account for language acquisition nor did the generative approach. The results went in favor of an Emergentist approach of language acquisition where both innateness and imitations were crucial constituents of children’s acquisition of linguistic forms.

The ten thousand Kims  

International Nuclear Information System (INIS)

In Korean culture, the names of family members are recorded in special family books. This makes it possible to follow the distribution of Korean family names far back in history. It is shown here that these name distributions are well described by a simple null model, the random group formation (RGF) model. This model makes it possible to predict how the name distributions change and these predictions are shown to be borne out. In particular, the RGF model predicts that for married women entering a collection of family books in a certain year, the occurrence of the most common family name 'Kim' should be directly proportional to the total number of married women with the same proportionality constant for all the years. This prediction is also borne out to a high degree. We speculate that it reflects some inherent social stability in the Korean culture. In addition, we obtain an estimate of the total population of the Korean culture down to the year 500 AD, based on the RGF model, and find about ten thousand Kims.

Use of 3D-computed tomography angiography for planning the surgical removal of pineal region meningiomas using Poppen's approach: a report of ten cases and a literature review  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background There are several treatment approaches for pineal region meningiomas, such as Poppen's approach, Krause's approach and combinations of the two approaches. We present our experience with the use of 3D-computed tomography angiography for planning the surgical removal of pineal region meningiomas using a suboccipital transtentorial approach (Poppen's approach and evaluate the role of Poppen's approach. Methods During the period from January 2005 to June 2010, ten patients presented to us with pineal region meningioma. MRI was routinely used to define the tumor size, position, and its relevant complications while 3D-CTA was applied to define the blood supply of the tumor and the venous complex (VC shift before operations. Most of the meningiomas had developed at both sides of the tentorial plane and extended laterally with typical characteristics of a pineal region tumor. Results All tumors were completely removed surgically without any injury to the VC. Postoperative intracranial infection occurred in one case who recovered after antibiotics were given. Postoperative intraventricular hemorrhage and pneumocephalus were found in one case, but fully recovered after conservative treatment. In the nine cases of concurrent hydrocephalus, this was gradually relieved in eight patients and the single case that became aggravated was successfully treated with ventriculoperitoneal shunt. Moreover, the follow-up MRI examinations did not indicate any recurrence of the meningiomas. Conclusion We found that the use of Poppen's approach is strongly supported for the successful removal of pineal region meningiomas without serious complications.

Full Text Available Background: Eccrine angiomatous hamartoma (EAH comprises a rare nevoid proliferation of normal eccrine glands and small blood vessels and occasionally otherelements in the middle and deep dermis with variable clinical manifestations.Case series have rarely been published except for case reports and literaturereviews. The aims of this article were to investigate the clinical and pathologic features of patients with EAH in Taiwan and to compare our resultswith the results of previous studies.Methods: A retrospective review of medical records and histopathological findings wasperformed on patients diagnosed with EAH in a medical center in Taiwanbetween 1994 and 2010.Results: Fifteen patients with pathologically diagnosed EAH were collected. Themean age at the time of diagnosis was 38.6 years (range, birth to 67 years.The male to female ratio was 3 to 2. In most cases, EAH arose as a singlelesion on a lower extremity. The symptoms and signs most commonly associated with EAH were pain (60%, hypertrichosis (13.3%, itching (13.3%and hyperhidrosis (6.7%. Additional pathological findings included hemangioma (13.3%, verrucous hemangioma (6.7%, arteriovenous malformation(6.7%, and angiokeratoma (6.7%. None of the patients experienced spontaneous regression of the lesions before excision. Excisions were done in onepatient under general anesthesia, and ten patients with local anesthesia. Fourpatients were kept under observation. Tumor recurrences were noted in twoout of the eleven patients whose lesions were excised.Conclusion: Compared with cases in the literature, we found additional histopathologicalfindings and an increased tumor recurrence risk in our cohort. EAH remainsa benign and uncommon hamartomatous condition. Further multi-center, retrospective studies with larger case numbers are needed to better characterizethe disease presentation in Asian populations.

Ten steps or climbing a mountain: A study of Australian health professionals' perceptions of implementing the baby friendly health initiative to protect, promote and support breastfeeding  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The Baby Friendly Hospital (Health Initiative (BFHI is a global initiative aimed at protecting, promoting and supporting breastfeeding and is based on the ten steps to successful breastfeeding. Worldwide, over 20,000 health facilities have attained BFHI accreditation but only 77 Australian hospitals (approximately 23% have received accreditation. Few studies have investigated the factors that facilitate or hinder implementation of BFHI but it is acknowledged this is a major undertaking requiring strategic planning and change management throughout an institution. This paper examines the perceptions of BFHI held by midwives and nurses working in one Area Health Service in NSW, Australia. Methods The study used an interpretive, qualitative approach. A total of 132 health professionals, working across four maternity units, two neonatal intensive care units and related community services, participated in 10 focus groups. Data were analysed using thematic analysis. Results Three main themes were identified: 'Belief and Commitment'; 'Interpreting BFHI' and 'Climbing a Mountain'. Participants considered the BFHI implementation a high priority; an essential set of practices that would have positive benefits for babies and mothers both locally and globally as well as for health professionals. It was considered achievable but would take commitment and hard work to overcome the numerous challenges including a number of organisational constraints. There were, however, differing interpretations of what was required to attain BFHI accreditation with the potential that misinterpretation could hinder implementation. A model described by Greenhalgh and colleagues on adoption of innovation is drawn on to interpret the findings. Conclusion Despite strong support for BFHI, the principles of this global strategy are interpreted differently by health professionals and further education and accurate information is required. It may be that the current processes used to disseminate and implement BFHI need to be reviewed. The findings suggest that there is a contradiction between the broad philosophical stance and best practice approach of this global strategy and the tendency for health professionals to focus on the ten steps as a set of tasks or a checklist to be accomplished. The perceived procedural approach to implementation may be contributing to lower rates of breastfeeding continuation.

Integrating ethics into case study assignments.  

Science.gov (United States)

I teach an upper-level writing course, Genes, Race, Gender, and Society, designed for Life Science majors, in which I utilize a case study to expose students to ethical ways of thinking. Students first work through the topical case study and then are challenged to rethink their responses through the lenses of ethics, taking into account different ethical frameworks. Students then develop their own case study, integrating ethical components. I want to expose my students to this way of thinking because I see technology being driven by the Jurassic Park phenomenon, "Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should," and want future physicians grounded in a sense of how their actions relate to the greater good.

Why Is Seed Production So Variable among Individuals? A Ten-Year Study with Oaks Reveals the Importance of Soil Environment  

Science.gov (United States)

Mast-seeding species exhibit not only a large inter-annual variability in seed production but also considerable variability among individuals within the same year. However, very little is known about the causes and consequences for population dynamics of this potentially large between-individual variability. Here, we quantified seed production over ten consecutive years in two Mediterranean oak species – the deciduous Quercus canariensis and the evergreen Q. suber - that coexist in forests of southern Spain. First, we calibrated likelihood models to identify which abiotic and biotic variables best explain the magnitude (hereafter seed productivity) and temporal variation of seed production at the individual level (hereafter CVi), and infer whether reproductive effort results from the available soil resources for the plant or is primarily determined by selectively favoured strategies. Second, we explored the contribution of between-individual variability in seed production as a potential mechanism of satiation for predispersal seed predators. We found that Q. canariensis trees inhabiting moister and more fertile soils were more productive than those growing in more resource-limited sites. Regarding temporal variation, individuals of the two studied oak species inhabiting these resource-rich environments also exhibited larger values of CVi. Interestingly, we detected a satiating effect on granivorous insects at the tree level in Q. suber, which was evident in those years where between-individual variability in acorn production was higher. These findings suggest that individual seed production (both in terms of seed productivity and inter-annual variability) is strongly dependent on soil resource heterogeneity (at least for one of the two studied oak species) with potential repercussions for recruitment and population dynamics. However, other external factors (such as soil heterogeneity in pathogen abundance) or certain inherent characteristics of the tree might be also involved in this process. PMID:25532130

Analysis of the Case Studies Video Recordings  

Directory of Open Access Journals (Sweden)

Full Text Available Case study method of didactic situations is a modern procedure of effective development of professional abilities in future teachers. I have been using the method for many years in future teachers training in the field of preparation of subject methodologies. A case study does not develop only the subject and didactic competences of future teachers. The self-evaluation and self-reflection processes in students also play an important role. For this purpose the third – analytical – phase of the study is carried out. Two basic methods are used for a complex analysis – macro-analytic and micro- analytic. The macro-analytic method is used to examine the course and the results of the case study: suitability of the used methods, forms and tools; using communicative tools, creating proper climate etc. The micro-analytic method is used to find out changes in students personalities and causes of the outer demonstrations of the case study. One of the examined phenomena is e.g. flexibility and creativity in adjusting the pre-concept to the course of the realization phase of the study.

External radiotherapy prior to thyroid cancer: A case-control study  

International Nuclear Information System (INIS)

The aim of this investigation was to study previous radiotherapy of malignant diseases as a risk factor for thyroid cancer. By using the Swedish Cancer Registry all cases of thyroid cancer with another malignant disease at least one year previously and living within the catchment area of the hospital were traced. During 1959-1989 a total of 1056 cases of thyroid cancer were identified. Of these, 37 had had another previous malignant disease and they constituted the cases in this study. As controls four persons with at least two malignant diseases, thyroid cancer excluded, were selected for each case from the same cancer registry. Ten (27.0%) of the 37 patients with thyroid cancer as a second tumor had earlier been irradiated with the treatment dose including the thyroid gland as compared with 34 (24.5%) of the 139 control patients. Eight of the ten cases with previous irradiation of the thyroid gland had papillary cancer. The median latency was 13 years. The estimated radiation dose in the thyroid varied between 3 and 40 Gy. External radiotherapy gave a crude odds ratio of 1.1 with 95% confidence interval = 0.5-2.8 for thyroid cancer. The weighted odds ratio was calculated to 2.3 with confidence interval = 0.5-8.9. This case-control study gave a nonsignificantly increased odds ratio for thyroid cancer in patients with external radiotherapy including the thyroid gland. 26 refs., 4 tabs

RADPHARM case presentation - CSF shunt function case study  

International Nuclear Information System (INIS)

A CSF shunt study is a non-invasive investigation that provides unique physiological information about the patency of a ventriculoperitoneal (VP) shunt. This study can be used to compliment information provided by other imaging modalities such as CT and MRI. A 21-year-old female who had a VP shunt inserted at the age of 4 months presented with persistent headache, vomiting and swelling over the right side of her face and neck. A CT scan of the brain was performed and showed no change in ventricular size to suggest the presence of hydrocephalus. However, symptoms persisted and the CT brain scan was repeated. Neck and lateral skull x-rays were also performed. The CT brain scan showed no change when compared to the previous results and the plain x-rays were not helpful as the VP shunt was radiolucent. A CSF shunt study was then performed. This demonstrated tracer accumulation in the right side of the neck adjacent to the shunt indicating a VP shunt fracture. SPECT/CT imaging then confirmed the site of shunt fracture in the mid right neck. It is clear from this case that Nuclear Medicine CSF shunt function studies provide specific physiological information about CSF shunts. For this patient the results of this study confirmed the suspected diagnosis of a shunt fracture, directing an uncomplicated surgical repair with the resolution of the patient's symptoms

The role of radionuclide studies in emergency cases  

International Nuclear Information System (INIS)

Radionuclide studies have been performed popularly because of its noninvasive and simple method recently. In this study, we applied this technique for the evaluation of emergency cases in cardiovascular diseases. There were 93 cases (1.5%) out of 6163 cases, done during 1981. The subjects were 34 cases of cardiac studies (9 cases of sup(99m)Tc-PYP myocardial imaging, 12 cases of thallium myocardial imaging, 13 cases of cardioangiography), 23 cases of peripheral diseases (12 cases of peripheral angiography, 11 cases of venography), 16 cases of pulmonary imaging, 10 cases of renal studies (6 cases of renal angiography, 9 cases of renal imaging) and 5 cases of brain angiography. These studies were proven to be useful clinically for the evaluation of emergency cases and follow-up studies. In the near future, ''emergency radionuclide studies'' would be benefit for the high-risk patients noninvasively. (author)

Capacity Ten-Seven  

Energy Technology Data Exchange (ETDEWEB)

The study was initiated to assemble UK solar experts who would define the parameters for the design of solar cell process plant with a capacity of about 10MWp per annum and establish the optimum substrate size, cell configuration and junction structure and show that these characteristics are suited to high volume low cost production. The study focused on proven materials and techniques rather than on innovative materials and processes. Peak production should deliver panels at a cost of less than $1 per peak watt. The study was reported under the headings of fundamental studies, front contact deposition, semiconductor deposition, rear contact deposition, cell isolation and initial design study. Since much of the work is commercially sensitive, not all findings are divulged in the report. The work, which achieved all its targets, was carried out by ICP Solar Technologies UK Ltd under contract to the DTI.

Clinicopathological study of 10 cases of post-irradiation sarcoma  

International Nuclear Information System (INIS)

Ten cases of post-irradiation sarcoma (3 in the bone and 7 in the soft tissue) are presented. Underlying diseases were malignant tumors in all cases. Irradiation doses were 5,000 rad or more. The latent period ranged from 7 years and 10 months to 17 years and 3 months. Post-irradiation sarcoma consisted of osteosarcoma in two cases, malignant fibrous histocytoma (MFH) of bone in one case, soft tissue MFH in five cases, ectosteal osteosarcoma in one case and suspected leiomyosarcoma in one case. Radical treatment is desirable for this disease. However, it might be impossible because diagnosis is often delayed as a result of chronic changes of the irradiated field. Even though the risk of post-irradiation sarcoma is considered, the use of radiotherapy can not be omitted when surgery alone is not sufficient for the treatment of malignant tumors. (Namekawa, K.)

Of the 96 operated tumors, only 11 had a follow-up time shorter than 2 years. Fifty-six patients were followed for at least 5 years, and 45 (47.3% for over 6 years. A single relapse was observed, which took place in the sixth year of observation. CONCLUSION: The Munich method is an efficient method of micrographic surgery, as good as the Mohs method. This study provides further evidence that the concept of micrographic surgery must be broadened to surgical excision with microscopic margin control, rather than linking it exclusively to the term "Mohs micrographic surgery".

Recurrent perinatal loss: a case study.  

Science.gov (United States)

To date, investigators have not demonstrated a clear relationship between a parent's history of prior perinatal losses and intensity of grief response following a subsequent perinatal loss. Examining this relationship for low-income, African-American parents is important because they are a vulnerable population due to the high incidence of perinatal mortality in Blacks and their other life stressors that can impact on grief response and caring needs. The purpose of this case study was to examine the impact of recurrent perinatal loss on a low-income African-American parent. The research design for this study was case report, using interview data collected from a mother who had recently experienced her fourth perinatal loss, which occurred at twenty-five weeks of gestation. Transcripts from two open-ended interviews were analyzed. The theoretical framework used to guide analysis of this case study was Lazarus and Folkman's stress and coping theory. Results demonstrated that the prior perinatal losses did not appear as critical components of the way the mother responded to her most recent loss. Instead, perception of the care she received from healthcare providers and how that care related to her experiences with her one living child who was born at the same gestational age was an important determinant in how she responded to her loss. The results of this case study demonstrate the importance assessing a person's perception of their experience and those factors which contribute to the way they respond. PMID:16871322

L’utilisation du TENS en physiothérapie : la situation particulière des soins palliatifs oncologiques  

Directory of Open Access Journals (Sweden)

Full Text Available Trans-cutaneous electrical nerve stimulation (TENS is a treatment against pain that uses the application of an electric current. Some studies suggest that TENS would reduce the pain associated with certain types of cancer and this treatment is regularly used in therapy in contexts of interdisciplinary practice specializing in palliative oncology. However, the use of TENS in cancer cases is a matter of controversy, and its application is contraindicated by Canadian standards governing the practice of physiotherapy. This article aims to present, through a case study, some principles to guide decision making regarding the choice of this therapy in cases of cancer. Scientific evidence, standards of practice and ethical principles that should guide the choice of therapy are discussed. The use of TENS therapy in palliative care is a paradigmatic example of a common situation: the weighing by health care professionals of the benefits and potential costs, such as potential adverse effects of treatment. In the case of TENS, the benefits are associated with the reduction of pain, while a potential adverse effect would increase tumour proliferation. This difficult calculation has implications for the various stakeholders such as patients and health professionals.

Frequency and antimicrobial resistance patterns of bacteria implicated in community urinary tract infections: a ten-year surveillance study (2000–2009  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Urinary tract infection (UTI is one of the most common infectious diseases at the community level. In order to assess the adequacy of the empirical therapy, the prevalence and the resistance pattern of the main bacteria responsible for UTI in the community (in Aveiro, Portugal was evaluated throughout a ten-year period. Methods In this retrospective study, all urine samples from patients of the District of Aveiro, in ambulatory regime, collected at the Clinical Analysis Laboratory Avelab during the period 2000–2009 were analysed. Samples with more than 105 CFU/mL bacteria were considered positive and, for these samples, the bacteria were identified and the profile of antibiotic susceptibility was characterized. Results From the 155597 samples analysed, 18797 (12.1% were positive for bacterial infection. UTI was more frequent in women (78.5% and its incidence varied with age, affecting more the elderly patients (38.6%. Although E. coli was, as usual, the most common pathogen implicated in UTI, it were observed differences related to the other bacteria more implicated in UTI relatively to previous studies. The bacteria implicated in the UTI varied with the sex of the patient, being P. aeruginosa a more important cause of infection in men than in women. The incidence of the main bacteria changed over the study period (P. aeruginosa, Klebsiella spp and Providencia spp increased and Enterobacter spp decreased. Although E. coli was responsible for more than an half of UTI, its resistance to antibiotics was low when compared with other pathogens implicated in UTI, showing also the lowest percentage of multidrug resistant (MDR isolates (17%. Bacteria isolated from females were less resistant than those isolated from males and this difference increased with the patient age. Conclusions The differences in sex and age must be taken into account at the moment of empirical prescription of antimicrobials. From the recommended antimicrobials by the European Association of Urology guidelines, the first line drugs (pivmecillinam and nitrofurantoin and the alternative antibiotic amoxicillin-clavulanic acid (AMX-CLA are appropriate to treat community-acquired UTI, but the fluoroquinolones should not be suitable to treat male infections and the trimethoprim-sulfamethoxazole (SXT shall not be used in the treatment of UTI at this level.

Waiting Lists for Radiation Therapy: A Case Study  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Why waiting lists arise and how to address them remains unclear, and an improved understanding of these waiting list "dynamics" could lead to better management. The purpose of this study is to understand how the current shortage in radiation therapy in Ontario developed; the implications of prolonged waits; who is held accountable for managing such delays; and short, intermediate, and long-term solutions. Methods A case study of the radiation therapy shortage in 1998-99 at Princess Margaret Hospital, Toronto, Ontario, Canada. Relevant documents were collected; semi-structured, face-to-face interviews with ten administrators, health care workers, and patients were conducted, audio-taped and transcribed; and relevant meetings were observed. Results The radiation therapy shortage arose from a complex interplay of factors including: rising cancer incidence rates; broadening indications for radiation therapy; human resources management issues; government funding decisions; and responsiveness to previous planning recommendations. Implications of delays include poorer cancer control rates; patient suffering; and strained doctor-patient relationships. An incompatible relationship exists between moral responsibility, borne by government, and legal liability, borne by physicians. Short-term solutions include re-referral to centers with available resources; long-term solutions include training and recruiting health care workers, improving workload standards, increasing compensation, and making changes to the funding formula. Conclusion Human resource planning plays a critical role in the causes and solutions of waiting lists. Waiting lists have harsh implications for patients. Accountability relationships require realignment.

Marketing and clinical trials: a case study  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Publicly funded clinical trials require a substantial commitment of time and money. To ensure that sufficient numbers of patients are recruited it is essential that they address important questions in a rigorous manner and are managed well, adopting effective marketing strategies. Methods Using methods of analysis drawn from management studies, this paper presents a structured assessment framework or reference model, derived from a case analysis of the MRC's CRASH trial, of 12 factors that may affect the success of the marketing and sales activities associated with clinical trials. Results The case study demonstrates that trials need various categories of people to buy in – hence, to be successful, trialists must embrace marketing strategies to some extent. Conclusion The performance of future clinical trials could be enhanced if trialists routinely considered these factors.

Shuttle Transportation System Case-Study Development  

Science.gov (United States)

A case-study collection was developed for NASA's Space Shuttle Program. Using lessons learned and documented by NASA KSC engineers, analysts, and contractors, decades of information related to processing and launching the Space Shuttle was gathered into a single database. The goal was to provide educators with an alternative means to teach real-world engineering processes and to enhance critical thinking, decision making, and problem solving skills. Suggested formats were created to assist both external educators and internal NASA employees to develop and contribute their own case-study reports to share with other educators and students. Via group project, class discussion, or open-ended research format, students will be introduced to the unique decision making process related to Shuttle missions and development. Teaching notes, images, and related documents will be made accessible to the public for presentation of Space Shuttle reports. Lessons investigated included the engine cutoff (ECO) sensor anomaly which occurred during mission STS-114. Students will be presented with general mission infom1ation as well as an explanation of ECO sensors. The project will conclude with the design of a website that allows for distribution of information to the public as well as case-study report submissions from other educators online.

Systemic Design: Two Canadian Case Studies  

Directory of Open Access Journals (Sweden)

Full Text Available This paper introduces two novel applications of systemic design to facilitate a comparison of alternative methodologies that integrate systems thinking and design. In the first case study, systemic design helped the Procurement Department at the University of Toronto re-envision how public policy is implemented and how value is created in the broader university purchasing ecosystem. This resulted in an estimated $1.5 million in savings in the first year, and a rise in user retention rates from 40% to 99%. In the second case study, systemic design helped the clean energy and natural resources group within the Government of Alberta to design a more efficient and effective resource management system and shift the way that natural resource departments work together. This resulted in the formation of a standing systemic design team and contributed to the creation of an integrated resource management system. A comparative analysis of the two projects identifies a shared set of core principles for systemic design as well as areas of differentiation that reveal potential for learning across methodologies. Together, these case studies demonstrate the complementarity of systems thinking and design thinking, and show how they may be integrated to guide positive change within complex sociotechnical systems.

The case study of biomaterials and biominerals  

Science.gov (United States)

The teaching of biomaterials as case study by on-line platform , susceptible to develop both individually and in groups, got different objectives proposed by the European Higher Education System, among which include: participate actively in the teaching-learning process by students, interpreting situations, adapt processes and solutions. It also improves oral and written communication, analytical skills and synthesis and also the ability to think critically. Biomaterials have their origin in biominerals. These are solid inorganic compounds of defined structure, consisting of molecular control mechanisms that operate in biological systems. Its main functions are: structural support, a reservoir of essential elements, sensors, mechanical protection and storage of toxic elements. Following the demand of materials compatible with certain functional systems of our body, developed biomaterials. Always meet the condition of biocompatibility. Should be tolerated by the body and do not provoke rejection. This involves a comprehensive study of physiological conditions and the anatomy of the body where a biomaterial has to be implemented. The possibility of generating new materials from biominerals has a major impact in medicine and other fields could reach as geology, construction, crystallography, etc. While the study of these issues is in its infancy today, can be viewed as an impact on the art and future technology. Planning case study that students would prepare its report for discussion in subgroups. Occurs then the pooling of individual analysis, joint case discussion and adoption by the subgroup of a consensual solution to the problem. The teacher as facilitator and coordinator of the final case analysis, sharing leads to group-wide class and said the unanimous decision reached by the students and gives his opinion on the resolution of the case.

Emergency preparedness case study: malignant hyperthermia.  

Science.gov (United States)

The second of this 2012 Case Study series addresses a situation that is uncommon in the surgical setting. Without proper recognition and prompt treatment, the mortality rate can be as high as 80% (Christiansen & Collins, 2004; Larach, Gronert, Allen, Brandom, & Lehman, 2010). With prompt recognition and intervention when this emergency does arise, the mortality rate has been reduced to 5% ((Rosenberg, Sambuughin, & Dirksen, 2010). Malignant hyperthermia (MH) is an inherited syndrome that affects 1 of 50,000 adults and 1 of 15,000 pediatric patients undergoing anesthetic procedures (Christiansen & Collins, 2004; Rosenberg et al., 2010). In this article, the reader is exposed to a case of MH and is asked a series of questions related to risk assessment, signs and symptoms, and nursing responsibilities. PMID:22647957

ISOE: Ten years of experience  

International Nuclear Information System (INIS)

The Information System on Occupational Exposure (ISOE), sponsored by the OECD Nuclear Energy Agency and the IAEA, was created in 1992 to facilitate information exchange between radiation protection experts from both operating organizations and national regulatory authorities and to enhance international co-operation on worker protection at nuclear power plants. The ISOE programme offers the world's largest database on occupational radiation exposure due to nuclear power plants covering, in 2001, 93% of the commercial power reactors in the world. In addition to providing the basis for analyses of dose trends, benchmarking and detailed studies, the ISOE also offers a system for rapid communication of radiation protection information and a forum for discussing occupational radiation exposure management issues through ISOE workshops and symposiums, organized annually. This paper is based on a report, published in 2002, summarizing the experience gained from ten years' of developing the ISOE and containing comments from participants on their experience with the system. Growing use of improved work management procedures, developed and published through the ISOE, has contributed to the downward trend in the annual average collective dose per reactor. The impact of a steam generator replacement on the evolution of this dose has also been demonstrated. To maintain or even further reduce the already low levels of occupational exposure, the ISOE needs to be regularly used and futhe ISOE needs to be regularly used and further promoted by its participants. In future, the ISOE can also play an important role in the decommissioning and dismantling of nuclear power plants. (author)

Reinforcement Learning algorithms offer interesting features for the control of autonomous systems, such as the ability to learn from direct interaction with the environment, and the use of a simple reward signalas opposed to the input-outputs pairsused in classic supervised learning. The reward signal indicates the success of failure of the actions executed by the agent in the environment. In this work, are described RL algorithmsapplied to two case studies: the Crawler robot and the widely known inverted pendulum. We explore RL capabilities to autonomously learn a basic locomotion pattern in the Crawler, andapproach the balancing problem of biped locomotion using the inverted pendulum.

The Danish National Case Study Report  

DEFF Research Database (Denmark)

This report is the Danish case study report in the EU-financed project INTERACTS, which analyses experience and expectations to the interaction between NGOs, Science Shops and universities. The report analyses potentials and barriers to NGO’s and similar civil society groups’ use of research and science through co-operation with Science Shops as a mediator between universities and civil society. The Danish national case study report analyses three projects carried out through the Science Shops at DTU and RUC. One case is a co-operation between two DTU students and an NGO, whom is working towards promoting the use of bicycles. The project addresses how different actors perceive and understand the bicycles as technology, and how this is incorporated in traffic strategies and planning. A second case is a co-operation between two DTU students and a day-care centre, aiming at investigating storage facilities for organic food and the possibilities of local supply of organic food to the day-care centre. The third case is a co-operation between four RUC students and a local branch of a larger NGO working with nature and environment. This co-operation aims at investigating the pollution level in a village pond. Each case is described and reflected separately. A cross-analysis analyses the interactions among the involved actor group (clients, students, researchers, and Science Shops) discussing how the knowledge in the projects were developed and how the knowledge were used by the actors to try to gain impact on either research development or societal discourses. When civil society groups request assistance through the Science Shops, their need for knowledge and research is based on a need for scientific documentation of a certain topic, a need for enhancement of new knowledge and/or a need for development of new solutions and perspectives to problems. All three types of knowledge need is covered by one or more of the cases. The cases show that NGOs perceive research done through universities as neutral and creating more legitimacy than research done by the organisation itself. The cases show that all three NGO’s have used the results and findings to try influencing the societal discourses, and that the results and findings have helped two of the NGOs to gain influence. The analysis further shows that this influence seems to depend on the ability of the NGOs to build alliances with other actors. Knowledge in itself is not enough to get influence. The cases show that some students choose to conduct research through the Science Shops, because their research can be beneficial for someone, who does not have access to science and knowledge. Aspects like the possibility of gaining skills in co-operation and communication and knowledge about real life problems are also part of the students’ considerations when they chose to co-operate with civil society organisations through a Science Shop. Supervisors and scientists get engaged in Science Shop projects either because the topic of the investigation is within their own research area, because they find the topic interesting or because they see the project as a possibility to recruit students for later thesis projects or research projects. The challenges in the co-operation with civil society groups are to secure the scientific level in the projects, design the projects so it fits into the university schedule, without leaving out the time perspective of the clients, and secure the research is applicable for the clients and based on their need for knowledge. The case studies have shown different roles of a Science Shop. All Science Shops have a role as mediator between science and civil society by establishing contact between students, researchers and civil society organisations, but a Science Shop can also have a role as incubator in curricula and research development within the university based on the knowledge needs raised by civil society organisations. Through these activities a Science Shop might contribute to societal discourses, like when the Science Shop at DTU started addre

A postural 'stressed' cerebral HMPAO case study  

International Nuclear Information System (INIS)

Full text: This case study represents an example of the utility of postural hypoperfusion stressed HMPAO SPECT. An elderly woman of 78 with a long history of giddiness was referred to our laboratory for examination of possible cerebral ischaemia. She had recurrent dizzy episodes, sometimes posture related, over the past few years and had suffered several falls. Cerebral DSA revealed minimal disease. CT scans were reported as normal. Carotid duplex Doppler studies revealed bilateral plaque disease in the carotid bulbs extending to the origins of the ICAs which were not significant stenoses. Postural symptoms were induced by standing the patient up rapidly and HMPAO was administered at the same time. A SPECT scan of the brain was performed. Quantitative analysis showed a left to right decrease of 10.8% in the temporo-occipital area, 5.6% in the temporo-parietal area and 2.5% in the cerebellar and parietal areas. Images revealed moderately reduced tracer concentration in the left half of the cerebellum and the left occipital region extending as far forward as the temporo-parietal region A repeat HMPAO SPECT scan without stress was normal. This would appear to indicate reversible ischaemia in the left posterior region, and is consistent with the reported symptoms. This case illustrates the usefulness of HMPAO in the diagnosis of reversible cerebral ischaemia

Energy Technology Data Exchange (ETDEWEB)

California is the largest cement producing state in theU.S., accounting for between 10 percent and 15 percent of U.S. cementproduction and cement industry employment. The cement industry inCalifornia consists of 31 sites that consume large amounts of energy,annually: 1,600 GWh of electricity, 22 million therms of natural gas, 2.3million tons of coal, 0.25 tons of coke, and smaller amounts of wastematerials, including tires. The case study summarized in this paperfocused on providing background information, an assessment ofenergy-efficiency opportunities and barriers, and program recommendationsthat can be used by program planners to better target products to thecement industry. The primary approach to this case study involvedwalk-through surveys of customer facilities and in depth interviews withcustomer decision makers and subsequent analysis of collected data. Inaddition, a basic review of the cement production process was developed,and summary cement industry energy and economic data were collected, andanalyzed. The analysis of secondary data provides background informationon the cement industry and identification of potential energy-efficiencyopportunities. The interviews provide some understanding of the customerperspective about implementation of energy-efficiencyprojects.

Commercializing Emerging Renewable Energy: A Case Study  

Directory of Open Access Journals (Sweden)

Full Text Available A broad scientific consensus exists that the global climate is changing. The Earth’s surface temperature could rise significantly over the next few decades, leading to us witnessing an entirely new and unknown planet. Improved energy efficiency, decreasing use of fossil fuels and wide diffusion of various renewable energy sources are among the focal measures to limit global warming to a sustainable level. The objective of this study is to analyse how renewable energy, such as wind power and bioenergy, could be efficiently commercialized. The evaluation is based on a case study and expert analyses exploiting lateral and parallel thinking methods, and group decision support systems tools. The results reveal that some of the generated ideas are ready for implementation to commercialize renewable energy, whereas others still require technical and commercial development and improvements before maturity.

A case study of scientific reasoning  

Science.gov (United States)

Concern is increasingly being expressed about the teaching of higher order thinking skills in schools and the levels of understanding of scientific concepts by students. Metaphors for the improvement of science education have included science as exploration and science as process skills for experimentation. As a result of a series of studies on how children relate evidence to their theories or beliefs, Kuhn (1993a) has suggested that changing the metaphor to science as argument may be a fruitful way to increase the development of higher order thinking skills and understanding in science instruction. This report is of a case study into the coordination of evidence and theories by a grade 7 primary school student. This student was not able to coordinate these elements in a way that would enable her to rationally consider evidence in relation to her theories. It appeared that the thinking skills associated with science as argument were similar for her in different domains of knowledge and context.

Management strategies in this sector have been increasingly important for long-term sustainability and competitiveness of business organizations. This study aims to analyze the interactions between apart-hotels and their stakeholders to foster an improvement of services provided, aligning the interface of strategic management from the point of view of managers and their key stakeholders. It is an exploratory study, with qualitative chacter, along with multiple case studies of the following establishments: Travel Inn, Hotels Slaviero and Etoile george v. Brazilian enterprises, which manage lodging facilities with apart-hotel concepts, combining features that enable comparative analysis of the study. For conceptual understanding, this study was based on literature about stakeholders, taking the work of Freeman (1984 and Freeman et al (2010 as main references. The research was conducted through semi-structured interviews with managers of lodging facilities and their key stakeholders and through direct observation and documentation. We found that not all groups of influence are considered in the planning of service flats. However, the organizations surveyed indicated that the market has realized the importance of the groups that exert influence and are influenced by their goals, and are therefore increasingly alert for integration of such groups in their strategic planning.

An STM and SXPS study of the interaction of C 60 with the ten-fold surface of the Al 72Ni 11Co 17 quasicrystal  

Science.gov (United States)

The adsorption of C 60 on the ten-fold surface of the decagonal Al-Ni-Co quasicrystal at room temperature has been investigated using scanning tunnelling microscopy (STM) and soft X-ray photoemission spectroscopy (SXPS). STM indicates disordered adsorption of intact C 60 molecules on the surface up to a coverage of 1 ML, followed by the formation of a C 60 multilayer. No step decoration is observed indicating that the molecules are immobile at room temperature. SXPS data of the Al 2p core level indicate a strong interaction of the C 60 molecules with the Al atoms of the substrate in the sub-monolayer regime. Valence band data indicate that the C 60 multilayer desorbs after annealing to 700 K leaving only the strongly bonded layer on the surface.

According to such a theory, the vacuum consists of flat four-dimensional space-time described by the Minkowski metric M4 and a compactified space B. The dimensions of B are small, and the space can only be observed at distance scales smaller than the present experimental limit. These theories have had serious difficulties. The equations of gravity severely restrict the possible choices for the space B. The allowed spaces are complicated and difficult to study. The vacuum is furthermore unstable in the sense that a small perturbation causes the compactified dimensions to expand indefinitely. There is an addition a semi-classical argument which implies that the compactified vacuum by annihilated by virtual black holes. It follows that a universe with compactified extra dimensions could not have survived to the present. These results were derived by applying the equations of general relativity to spaces of more than four dimensions. The form of these equations was assumed to be unchanged by an increase in the number of dimensions. The authors illustrate the effect of such terms by considering the example B = S6 where S6 is the six-dimensional sphere. Only when the extra terms are included is this choice of the compactified space allowed. He explore the effect of a small perturbation on suchthe effect of a small perturbation on such a vacuum. The ten-dimensional spherically symmetric potential is examined, and I determine conditions under which the formation of virtual black holes is forbidden. The examples M4 x S6 is still plagued by the semi-classical instability, but this result does not hold in general. The requirement that virtual black holes be forbidden provides a test for any theory which predicts a compactified vacuum

Positive effect of removal of subchondral bone plate for cemented acetabular component fixation in total hip arthroplasty: a randomised RSA study with ten-year follow-up.  

Science.gov (United States)

We hypothesised that the removal of the subchondral bone plate (SCBP) for cemented acetabular component fixation in total hip arthroplasty (THA) offers advantages over retention by improving the cement-bone interface, without jeopardising implant stability. We have previously published two-year follow-up data of a randomised controlled trial (RCT), in which 50 patients with primary osteoarthritis were randomised to either retention or removal of the SCBP. The mean age of the retention group (n = 25, 13 males) was 70.0 years (sd 6.8). The mean age in the removal group (n = 25, 16 males) was 70.3 years (sd 7.9). Now we have followed up the patients at six (retention group, n = 21; removal group, n = 20) and ten years (retention group: n = 17, removal group: n = 18), administering clinical outcome questionnaires and radiostereometric analysis (RSA), and determining the presence of radiolucent lines (RLLs) on conventional radiographs. RSA demonstrated similar translation and rotation patterns up to six years. Between six and ten years, proximal acetabular component migration and changes of inclination were larger in the retention group, although the mean differences did not reach statistical significance. Differences in migration were driven by two patients in the SCBP retention group with extensive migration versus none in the SCBP removal group. The significant difference (p < 0.001) in the development of radiolucent lines in the retention group, previously observed at two years, increased even further during the course of follow-up (p < 0.001). While recognising SCBP removal is a more demanding technique, we conclude that, wherever possible, the SCBP should be removed to improve the cement-bone interface in order to maximise acetabular component stability and longevity.

[Nosocomial legionellosis: study of 51 cases].  

Science.gov (United States)

We report the features of 51 cases of hospital-acquired Legionella pneumophila pneumonia (HLP), diagnosed in our hospital during a period of about 5 years. Mean age was 64.6 years, and the male:female ratio 1.6. 29% of HLP involved patients who were not admitted to the hospital at the time of diagnosis. The monthly distribution showed a maximal incidence in July and August. Only 6% of cases involved patients without underlying diseases. The most common underlying diseases were chronic obstructive lung disease (COLD) (37%), heart disease (29%) and immunosuppressant therapy (29%). 21% of the patients with renal transplant had HLP. The only constant clinical feature was fever of 37.8 degrees C or higher. During the first 24-48 hours of illness, respiratory symptoms were not present in 41% of cases, and thoracic abnormalities in the physical examination were not present in 31%. The laboratory abnormalities were nonspecific and with incidence rates lower than 50%. In 41% of patients there was hypoxemia (60 mmHg or lower) with FiO2 of 0.21. The most common radiological finding was the initial unilateral and unilobar involvement. Pleural effusion and cavitation developed in 20% and 4%, respectively. Overall mortality rate was 12%. In the 43 patients treated early with intravenous erythromycin, mortality rate was 7%. We think that the relatively low incidence of severe underlying immunosuppression and the inclusion of hospital-acquired pneumonia in our institution influenced the low mortality rate of the present study, in contrast with other series of hospital-acquired legionellosis.

Microgravity isolation system design: A case study  

Science.gov (United States)

Many acceleration-sensitive, microgravity science experiments will require active vibration isolation from manned orbiters on which they will be mounted. The isolation problem, especially in the case of a tethered payload, is a complex three-dimensional one that is best suited to modern-control design methods. In this paper, extended H(sub 2) synthesis is used to design an active isolator (i.e., controller) for a realistic single-input-multiple-output (SIMO) microgravity vibration isolation problem. Complex mu-analysis methods are used to analyze the isolation system with respect to sensor, actuator, and umbilical uncertainties. The paper fully discusses the design process employed and the insights gained. This design case study provides a practical approach for isolation problems of greater complexity. Issues addressed include a physically intuitive state-space description of the system, disturbance and noise filters, filters for frequency weighting, and uncertainty models. The controlled system satisfies all the performance specifications and is robust with respect to model uncertainties.

Histopathological Study of 100 Cases of Vasculartumours  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction: Vascular tumors show a broad variety of morphological appearances and cilinical behavior, the lesions are ranging from benign hemangiomas to intermediate lesion, which are locally aggressive, to highly malignant angiosarcoma. There is also the grey zone between true neoplasia and hamartoma, which makes difficulty in histopathological assessment. It is also important to decide the degree of malignancy as it can strongly influence the choice of treatment and prognosis. Methodology: Hundred cases of vascular tumors received at the department of pathology, medical college and SSG hospital, Baroda have been studied with a view to carrying out a histopathological analysis. Results: mploying modified Enzinger’s classification (2001 the break up of 100 cases was as follows : 37 – capillary hemangiomas, 26 – granuloma pyogenicum, 15 – cavernous hemangiomas, 07 – lymphangiomas, 04 – masson’s hemangiomas (papillary endothelial hyperplasia, 03 – epithelioid hemangiomas, 03 – lymphangiomas circumscriptum, 01 – cystic hygroma, 01 – spindle cell hemangioendothelioma, 01 – epithelioid hemangioendothelioma, 01 – glomus tumor, 01 – angiosarcoma. Majority of vascular tumors were benign, more common in children and young adults, most common sites were head and neck, which required only local surgical excision. Conclusion: Malignant and intermediate tumors formed as extremely small proportion of vascular tumors, which should be treated aggressively and closely followed up.

Building Energy Information Systems: User Case Studies  

Energy Technology Data Exchange (ETDEWEB)

Measured energy performance data are essential to national efforts to improve building efficiency, as evidenced in recent benchmarking mandates, and in a growing body of work that indicates the value of permanent monitoring and energy information feedback. This paper presents case studies of energy information systems (EIS) at four enterprises and university campuses, focusing on the attained energy savings, and successes and challenges in technology use and integration. EIS are broadly defined as performance monitoring software, data acquisition hardware, and communication systems to store, analyze and display building energy information. Case investigations showed that the most common energy savings and instances of waste concerned scheduling errors, measurement and verification, and inefficient operations. Data quality is critical to effective EIS use, and is most challenging at the subsystem or component level, and with non-electric energy sources. Sophisticated prediction algorithms may not be well understood but can be applied quite effectively, and sites with custom benchmark models or metrics are more likely to perform analyses external to the EIS. Finally, resources and staffing were identified as a universal challenge, indicating a need to identify additional models of EIS use that extend beyond exclusive in-house use, to analysis services.

Cancer preceding Wegener's granulomatosis: a case-control study  

DEFF Research Database (Denmark)

OBJECTIVE: To investigate whether patients with WG have an increased risk of malignancies prior to and/or around the time of the vasculitis diagnosis, as suggested by previous studies. METHODS: A total of 293 WG patients were included in the study. Ten gender- and age-matched controls were selected randomly for each patient from the Danish Central Population Register. Information on malignancies was obtained through the Danish Cancer Registry. Occurrence of malignancies before WG diagnosis among patients and before WG diagnosis of their matched case among controls (reference date) was compared by calculation of prevalence odds ratios (OR). RESULTS: Twenty-six patients were diagnosed with cancer before WG, while 194 controls were diagnosed with cancer before the reference date (OR 1.4; 95% CI 0.9, 2.2). Among specific malignancies, a significantly increased prevalence was found for testis cancer (OR 6.4; 95% CI 1.1, 38) based on two patients, who developed testis cancer >10 years before WG. The overall prevalence of malignancies diagnosed <2 years before WG was not significantly increased (OR: 1.6; 95% CI: 0.8, 3.4), but non-melanoma skin cancer occurred with an increased prevalence within this time interval (OR 4.0; 95% CI 1.4, 12). CONCLUSIONS: We did not find clear evidence of an increased prevalence of preceding cancer in our WG cohort, indicating that shared risk factors are of minor importance for the excess of malignancies that occur in WG patients after the vasculitis diagnosis. Furthermore, our current and previously reported latency analyses do not substantiate that serious malignancies play a significant role in the pathogenic events that trigger development of WG.

Understanding Support - lessons from a case study  

Directory of Open Access Journals (Sweden)

Full Text Available Support from top management and others is agreed to be an important factor in information systems success and failure, but little is written about how it has its effect and how it might be managed to a project's advantage. A recently developed conceptual framework is described. It covers the nature and forms of support, the way support affects project outcomes, the bases on which support is provided, and the strategies by which support may be managed. The framework is used to analyse a case study in several stages. At the end of the analysis of each stage, the framework's utility is assessed in terms of its explanatory value and the practical advice it suggests. Areas for further research are identified.

Case study on industrial hazmat response teams.  

Science.gov (United States)

In 1991, Amway formed an industrial hazardous materials (hazmat) team in order to respond quickly and efficiently to potential chemical spills. The company's goals were, and still are today, to protect employees, the environment and the local community, and to reduce the amount of resulting downtime. In 1991, the hazmat team was very well funded, enabling it to become a discrete department with its own management staff and nearly 100 hazmat volunteers. Due to changes in the business climate, Amway reorganised in 2000/01, and the hazmat team became part of a company that incorporated contract work into its scope. When this reorganisation occurred, the hazmat team was thoroughly re-evaluated. Its response function was maintained, but was systematically reinvented in the most lean way practicable while still meeting corporate goals. This case study represents Amway's hazmat team's journey through the evaluation process and subsequent reorganisation. PMID:20378491

Full Text Available In todays economics, the fact that information is a major factor of production and of increasing importance as a source of competitive advantage is a generally accepted truism. The trend towards global markets has strongly impacted the competitive situation of many enterprises. Never has the economic environment been subject to so many drastic and rapid changes. This put new weight factors on the requirements for design of business process. This paper explores the case of an Italian legal office that has studied more and more innovative solutions both to satisfy the demands of the clienteles and to oppose the action of the new competitors. Comparing classic models and the theories of Porter with the characteristics and needs of new economy, it shows as the ability to possess, to easily have access, to creatively use of information constitutes one of the more strategic sources of the competitive advantage.

Management by Values: A Case Study  

Directory of Open Access Journals (Sweden)

Full Text Available

The intention of this paper is to conclude the management approach by the case study of Chinese enterprise. There are a lot of management approaches in practice, one of the most influential and famous one is management by objective which is invented by the father of modern management discipline Peter F Drucker, he observed the case of American most successful enterprise such as GM and then concluded and created the relevant meaningful management tools, in effect, such valuable management theory is stemmed from the practice of management, and the premise is that there must have great enterprise first then the effective management way could be concluded, therefore, many management theories are created in America because that the US have many great organizations other countries did not have at that time. However, after more than thirty years’ efforts and accumulation of the development of reform and openingup in China, it is our pride that such accumulation has lead to a lot of successful enterprises in China, one of such great companies is Alibaba, which is created at the right time and the right place. Alibaba is chosen because that the reason of its success is different with other enterprises in China and even in the world, it is a company which never place high value on benefit, however, it is more successful than any other companies which are benefit-oriented, by the case study we find out that the secret of its success is nothing but an innovational practice of management, that is, Management by Values (MBV. As it is shown in this paper: Alibaba, the mission of which is to create easy way to trade anywhere. Such visionary mission gives Alibaba a dream of unlimited growth space, but only the mission itself is not enough, effective management by values helps Alibaba to realize this potential. Its practice implies the content of values and how to manage it in an organization; besides, it tells us the bases of managing by values, which are about the character of the leader and the purpose of the organization, Jack ma and Alibaba are good cases in point, Jack ma himself is poor in education, but he is really a practical dreamer and is also a leader who is good at developing others, as an organization , the purpose of Alibaba is the benefit of outside instead of its profit, both are really precious in today’s business; and what is more, its experience also witnesses the process of management by values: start an enterprise with an agreeable basic principles of values ; shaping the values when the enterprise begin to take shape; evaluating the values of all the employees when the enterprise become big; at last, the developing of values itself should be an important part of this management, which part of the values should be persisted, which part might be changed, Alibaba provide us a good case in point.

A case study in pathway knowledgebase verification  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Biological databases and pathway knowledgebases are proliferating rapidly. We are developing software tools for computer-aided hypothesis design and evaluation, and we would like our tools to take advantage of the information stored in these repositories. But before we can reliably use a pathway knowledgebase as a data source, we need to proofread it to ensure that it can fully support computer-aided information integration and inference. Results We design a series of logical tests to detect potential problems we might encounter using a particular knowledgebase, the Reactome database, with a particular computer-aided hypothesis evaluation tool, HyBrow. We develop an explicit formal language from the language implicit in the Reactome data format and specify a logic to evaluate models expressed using this language. We use the formalism of finite model theory in this work. We then use this logic to formulate tests for desirable properties (such as completeness, consistency, and well-formedness for pathways stored in Reactome. We apply these tests to the publicly available Reactome releases (releases 10 through 14 and compare the results, which highlight Reactome's steady improvement in terms of decreasing inconsistencies. We also investigate and discuss Reactome's potential for supporting computer-aided inference tools. Conclusion The case study described in this work demonstrates that it is possible to use our model theory based approach to identify problems one might encounter using a knowledgebase to support hypothesis evaluation tools. The methodology we use is general and is in no way restricted to the specific knowledgebase employed in this case study. Future application of this methodology will enable us to compare pathway resources with respect to the generic properties such resources will need to possess if they are to support automated reasoning.

Problem-based case study to enhance critical thinking in student nurses  

Directory of Open Access Journals (Sweden)

Full Text Available The use of traditional teaching methods, for example the lecture method, does not stimulate critical thinking in student nurses. This problem can be solved by the utilisation of problem-based case study in the classroom/clinical setting. The purpose of this study is to describe guidelines for the implementation of problem-based case study in a clinical setting among first year, comprehensive course students at the Northern Province College of Nursing: Sovenga campus. The research design of this study was qualitative, explorative, descriptive and contextual and was conducted in the following phases: Phase 1: The development and implementation of a program for problem-based case study in the clinical setting; Phase II: The experiences of student nurses who were exposed to problem-based case study in the clinical setting; Phase III: The perceptions of tutors regarding the implementation of problem-based case study in the clinical setting (focus group, and; ase IV: Guidelines for the implementation of problem-based case study. The data from Phases I, II and III were used to formulate guidelines for the implementation of problem-based case study. The sample group consisted of all 69 first year student nurses at the Northern Province College of Nursing: Sovenga campus and ten tutors teaching clinical courses at the same campus. The Tesch (1990 approach is used for data analysis. Nine guidelines for the implementation of a problem-based case study approach were formulated and recommendations for development of an instrument to measure critical thinking in nursing were recommended.

Elegant solutions ten beautiful experiments in chemistry  

CERN Document Server

Devising and performing a scientific experiment is an art, and it is common to hear scientists talk about the 'beauty' of an experiment. What does this mean in chemistry, the experimental science par excellence? And what are the most beautiful chemical experiments of all time? This book offers ten suggestions for where beauty might reside in experimental chemistry. In some cases the beauty lies in the clarity of conception; sometimes it is a feature of the instrumental design. But for chemistry, there can also be a unique beauty in the way atoms are put together to make new molecules, substanc

Groundwater study by using radioisotope tracer - some case studies  

International Nuclear Information System (INIS)

This study is to investigate the groundwater behaviour by using radioisotope tracer. The main objectives of the study are to determine the groundwater flowrate and its direction. The equipment that we used in this study are rheometer and direction monitoring system - MINT water spy. In this study, the single well method is used to determine the groundwater velocity and direction. The method involved the injection of radioisotope tracer into the borehole and monitor its concentration over a certain period of time. Radioactive isotopes artificially injected at a well-define point of the system under investigation. Groundwater movement studies have been performed for example in Paya Terubong (Penang), Klian Intan (Perak), and Taman Makmur (Negeri Sembilan). The application of these techniques have shown that in many cases they not only confirm the results obtained by classical hydrological methods but as an alternative they provide more information and immediate answers to some hydrological problems.

EST Case Studies and Perspectives in Japan  

International Nuclear Information System (INIS)

Results and discussion of the Environmentally Sustainable Transport (EST) Case Study for Japan are introduced within this paper. According to procedures defined in the EST project by the OECD, the targets for a major reduction of environmental load within the transport sector are defined to be CO2, NOx, PM, and VOC. Three scenarios to accomplish these reduction targets, with respect to these environmental loads are detailed: a techno-optimistic scenario (EST1), a transport demand management scenario (EST2), and a composite scenario (EST3). All of the scenarios are examined and compared to the business-as-usual (BAU) scenario. Policy instruments to realize these scenarios and their socio-economic impacts were, to date, not assessed within the study. Utilizing a 'back casting' methodology, expected changes in technology and transport behavior in order to meet an ultimate target of emissions reduction were examined by each of the scenarios. The objective areas consisted of a national study, encompassing the whole of Japan, and a regional (Aichi prefecture) study. The forecasts indicate that CO2 emissions increase by about 10% in Japan but are almost stable in Aichi prefecture. NOx and HC emissions in 2030 are about half, and PM emissions around one quarter of those in 1990 in Aichi prefecture. The results of the back casting indicate that CO2 and NOx reduction targets have severely restrictive conditions. The achievement of targets utilizing only EST1 and EST2 is totallyts utilizing only EST1 and EST2 is totally unfeasible. Even in the combined EST3 scenario, and in light of current trends requirements must include strong recommendations for change such as the significant wide spread use of fuel cell vehicles and the reduction of freight transport demands, and hence the scenario still needs to be discussed further

Go with the flow: A case study  

Energy Technology Data Exchange (ETDEWEB)

Full text: A 55-year-old female presented to the Alfred Emergency Department semi-conscious with frank rectal bleeding requiring blood volume replacement. Labelled red blood cell (RBC) scintigraphy was requested in order to locate the site of bleeding. In vitro labelling of 3 mL of patient``s blood was performed (PYP as a diluted tinning agent and 1 GBq of freshly eluted {sup 99}mTc) and suspended red cells were injected. Using a GE Starcam system with high resolution collimation, images were acquired for 30 seconds (2 s per frame) and thereafter continuously for 1. 5 hours (30 s per frame). During imaging, patient history became available revealing portal hypertension, oesophageal and anal varices due to myelofibrosis and previous cholecystectomy. Initial flow images showed bizarre abdominal collateral vessels. Accumulation of labelled RBC over 1.5 hours in the right upper quadrant indicated the hepatic flexure as the site of bleeding. The initial flow study showing major porto-systemic collateral vessels indicated that therapeutic embolisation via angiography would be life threatening. The patient underwent emergency hemicolectomy and has been bleed-free to date. In this case, delayed RBC scintigraphy accurately located the haemorrhage site. However, the initial flow study demonstrating major vessel collateral flow was crucial in contraindicating angiographic embolisation. Surgery was then the only therapeutic option.

Case Study on Printed Matter in Denmark  

DEFF Research Database (Denmark)

The implementation of the EU REACH regulation will most probably promote substitution within sectors handling a lot of different chemicals such as the printing industry. With the aim of being at the cutting edge of this development, the Danish printing industry started up a substitution project in 2006. A major part of the work has been mapping the presence of chemicals, which are the potential candidates for substitution (e.g., PBT, CMR, vPvB, EDS). The mapping comprises a combination of a literature study and an investigation of the actual (2007) presence of candidate substances at 15 Danish printing houses including the examination of almost 900 MSDSs (i.e., products). Furthermore, a focused search in the Danish Product Register has been included. More than 200 of the mapped substances are candidates for substitution according to Danish legislation (List of Undesirable Substances) and about 60 of these substances fulfill one or more of the criteria (e.g., CMR, EDS) for the REACH Annex XIV candidate list (Authorisation List). This case study presents the results of the mapping of chemical substitution candidates some of which may be relevant regarding accumulation of additives/impurities in globally recycled paper.

Antineutrino reactor safeguards - a case study  

CERN Document Server

Antineutrinos have been proposed as a means of reactor safeguards for more than 30 years and there has been impressive experimental progress in neutrino detection. In this paper we conduct, for the first time, a case study of the application of antineutrino safeguards to a real-world scenario - the North Korean nuclear crisis in 1994. We derive detection limits to a partial or full core discharge in 1989 based on actual IAEA safeguards access and find that two independent methods would have yielded positive evidence for a second core with very high confidence. To generalize our results, we provide detailed estimates for the sensitivity to the plutonium content of various types of reactors, including most types of plutonium production reactors, based on detailed reactor simulations. A key finding of this study is that a wide class of reactors with a thermal power of less than 0.1-1 GWth can be safeguarded achieving IAEA goals for quantitative sensitivity and timeliness with detectors right outside the reactor ...

Diversity management in a South African university: A case study  

Directory of Open Access Journals (Sweden)

Full Text Available To establish the perception of employees regarding diversity management at South Africa's largest residential university, the questionnaires of Gardenswartz & Rowe (1993 was adapted and a case study approach with a sample of 25 employees was used. The diversity audit measured the sample's perceptions on symptoms of diversity related problems; openness to change of the university; the status quo regarding diversity management; organisational barriers to diversity; the valuing of diversity; and the management of diversity by managers or supervisors. It was found that a high number of symptoms of diversity-related problems are perceived and that respondents believed that the university is relatively unresponsive to the need to change. The university was believed to be in a mono cultural stage of development and barriers to developing into a multicultural organisation were identified. Respondents did report a very positive attitude towards diversity but perceived that certain procedures are not supportive.

Extraskeletal mesenchymal chondrosarcoma: an imaging review of ten new patients  

International Nuclear Information System (INIS)

Extraskeletal mesenchymal chondrosarcoma (EMC) is a rare soft-tissue tumor that most arises in young adults. Because of its rarity, few imaging studies have been reported to date. The purpose of this study was to elucidate the imaging features of this tumor. We conducted a multi-institutional study in cooperation with five referral cancer centers in Japan. Imaging findings of ten new EMC cases, including conventional radiography, computed tomography (CT), and magnetic resonance imaging (MRI), performed at each institute, were reviewed along with clinical features. Ten patients with EMC, who had been treated at each hospital from 1990 to 2001, participated in this study. Soft-tissue masses with well-demarcated, dense and granular calcification were most frequently observed on plain radiographs and CT scans. T2-weighted MR images most clearly depicted a two-component structure composed of calcified and uncalcified areas, and enhanced MRI showed inhomogeneous enhancement in both areas. Although the sensitivity and specificity of these findings are unknown, they might be characteristic and have diagnostic value for this rare tumor. (orig.)

Guidelines for Conducting Positivist Case Study Research in Information Systems  

Directory of Open Access Journals (Sweden)

Full Text Available The case study research approach is widely used in a number of different ways within the information systems community. This paper focuses on positivist, deductive case study research in information systems. It provides clear definitions of important concepts in positivist case study research and illustrates these with an example research study. A critical analysis of the conduct and outcomes of two recently published positivist case studies is reported. One is a multiple case study that validated concepts in a framework for viewpoint development in requirements definition. The other is a single case study that examined the role of social enablers in enterprise resource planning systems implementation. A number of guidelines for successfully undertaking positivist case study research are identified including developing a clear understanding of key concepts and assumptions within the positivist paradigm; providing clear and unambiguous definitions of the units and interactions when using any theory; carefully defining the boundary of the theory used in the case study; using hypotheses rather than propositions in the empirical testing of theory; using fuzzy or probabilistic propositions in recognising that reality can never be perfectly known; selecting case studies carefully, particularly single case studies; and recognising that generalisation from positivist, single case studies is inherently different from generalisation from single experiments. When properly undertaken, positivist, deductive case study research is a valuable research approach for information systems researchers, particularly when used within pluralist research programs that use a number of different research approaches from different paradigms.

Efficacy and safety of ten day moxifloxacin 400 mg once daily in the treatment of patients with community-acquired pneumonia. Community Acquired Pneumonia Study Group.  

Science.gov (United States)

Community-acquired pneumonia (CAP) remains a common and serious illness with approximately 2-4 million cases reported annually. Management of CAP is therapeutically challenging due to the increasing prevalence of penicillin- and macrolide-resistant pneumococci and beta-lactamase producing Haemophilus influenzae, as well as the increased recognition of 'atypical' pathogens, such as Chlamydia pneumoniae and Mycoplasma pneumoniae, and the frequent need for empiric therapy. We aimed to evaluate the safety and efficacy of moxifloxacin in the treatment of patients with CAP. To do this we carried out a prospective, uncontrolled, non-blind, Phase III clinical trial, in 27 U.S. centers. Patients included in the study were over 18 years of age with signs and symptoms of CAP confirmed by evidence of a new or progressive infiltrate on chest radiograph. The intervention used was moxifloxacin 400 mg PO once daily for 10 days. Sputum samples were collected pretherapy for Gram stain and culture for typical organisms. Culture and serological testing for Chlamydia pneumoniae and Mycoplasma pneumoniae was also performed. Susceptibility to moxifloxacin was determined by disk diffusion and MIC. Clinical and bacteriological responses were determined at the end of therapy (0-6 days post-therapy), follow-up (14-35 days post-therapy) and overall (end of therapy plus follow-up). Analyses were performed on both valid for efficacy and intent-to-treat populations. The primary efficacy variable was overall clinical resolution. Of 254 patients enrolled in the Study, 196 patients were included in the efficacy analyses. The majority of patients were male (58%) and Caucasian (85%) with a mean age of 49 years (range: 18 to 85 years). Only 3% of patients were hospitalized pretherapy. The most common pretherapy organisms identified, by culture or serology, in the valid for efficacy population (i.e. 147 organisms among 116 patients), were: Chlamydia pneumoniae (n=63; 54%), Mycoplasma pneumoniae (n=29; 25%), Streptococcus pneumoniae (n=14; 12%) and Haemophilus influenzae (n=13; 10%). End of therapy, follow-up and overall clinical resolution rates for the valid for efficacy population were 94%, 93% and 93%, respectively. The 95% CI for the overall clinical resolution rate was 88.1%, 95.9%. The overall bacteriological response for patients diagnosed by culture or serological criteria, was 91% (95% CI=84%, 96%). For patients who only met serological criteria for infection, the overall bacteriological response was 94% (60/64). Bacterial response rates for the four most commonly isolated pathogens were: 89% (56/63) for C. pneumoniae, 93% (27/29) for M. pneumoniae, 93% (13/14) for S. pneumoniae and 85% (11/13) for H. influenzae. Drug-related adverse events were reported in 33% (85/254) of moxifloxacin-treated patients. Nausea (9%), diarrhea (6%) and dizziness (4%) were the most commonly reported adverse events. Atypical organisms were isolated in high frequency among patients with CAP. Moxifloxacin 400 mg once daily for 10 days was effective and well-tolerated in the treatment of these adult patients with CAP. Moxifloxacin offers an effective treatment alternative for CAP due to both typical and atypical bacterial pathogens. PMID:10714413

A case study in coastal flooding analysis  

Science.gov (United States)

Floods are among the most frequent and costly natural disasters in terms of human hardship and economic loss. Depending on topography, soil condition, ground cover, human settlements and other factors, flood can produce catastrophic impacts both in terms of damages and modification of the landscape. The Salerno province experienced numerous flooding events after heavy thunderstorm, that triggered intense landslides (debris-mudflow), inundations, denudation, shore line progradation, etc. Recent study (Porfido et al. 2009) show that in this area more than 100 flooding events occurred since 1500. Among these four events have been estimate in the maximum severity class. Research into the historical flooding highlights the case of the event of 11 November 1773 as one of the major flooding occurred in Cava de' Tirreni, Campanian region, Southern Italy. About 400 - 450 people died; severe damage to the buildings were registered in a wide area of the Salerno province; several mud flows invested large areas of coastal territory which caused progradation phenomena of the shoreline of several hundreds of meters. The main objectives of this paper are: the historical reconstruction of the event considering contemporary documents found at Archives and National Libreries; characterization of the rainfall timing using historical descriptions; delimitation of inundated area; distribution of damage levels and identification and classification of flood-induced geological phenomena.

Hybrid Risk Management Methodology: A Case Study  

Directory of Open Access Journals (Sweden)

Full Text Available Risk management is a decision-making process involving considerations of political, social, economic and engineering factors with relevant risk assessments relating to a potential hazard. In the last decade, a number of risk management tools are introduced and employed to manage and minimize the uncertainty and threats realization to the organizations. However, the focus of these methodologies are different; in which companies need to adopt various risk management principles to visualize a full picture of the organizational risk level. Regarding to this, this paper presents a new approach of risk management that integrates Hierarchical Holographic Modeling (HHM, Enterprise Risk Management (ERM and Business Recovery Planning (BCP for identifying and assessing risks as well as managing the consequences of realized residual risks. To illustrate the procedures of the proposed methodology, a logistic company ABC Limited is chosen to serve as a case study Through applying HHM and ERM to investigate and assess the risk, ABC Limited can be better evaluated the potential risks and then took the responsive actions (e.g. BCP to handle the risks and crisis in near future.

Case studies: Redevelopment of former industrial sites  

International Nuclear Information System (INIS)

This paper presents the case studies of the redevelopment of two sites: Herr's Island, located in the Allegheny River in Pittsburgh, Pennsylvania and the Union Pacific Resources Company's site located near the Port of Long Beach in Wilmington, California. The common goal in cleaning up both sites is the transformation of environmentally unsound property into flourishing residential and commercial use. Herr's Island site has included a petroleum refinery, an asphalt plant, pipe mills, a meat packing plant, and a transformer dismantling facility. A small portion of the island was investigated as part of a Phase 2 audit. The investigation identified contamination in the southern portion of the island with maximum polynuclear aromatic hydrocarbon (PAH) and polychlorinated biphenyl (PCB) concentrations in soils at 40 and 200 parts per million (ppm), respectively. The Union Pacific Resources Company (UPRC) site, located in Wilmington, California, is situated within a 600-acre oil field production area. A phased remedial investigation (RI) of the site was initiated in 1991 pursuant to a consent agreement between UPRC and the California Department of Toxic Substances Control (DTSC). The RI identified the presence of volatile organic compounds (VOCs), semi-volatile organic compounds, chlorinated pesticides, PAHs, PCBs and metals at various concentrations throughout the soils. VOCs and metals were also detected in the groundwater. In particular, arsenic, benzene, vinyl chloriderticular, arsenic, benzene, vinyl chloride, and mercury were encountered at concentration levels at, or slightly above, drinking water standards in a few samples

CONCLUSÃO: Os astrocitomas subependimários de células gigantes em pacientes com ET em geral apresentam-se como lesão única próxima ao forame de Monro, com médio sinal nas imagens ponderadas em T1, alto sinal em T2 e realce intenso após a administração de contraste.OBJECTIVE: To report the magnetic resonance imaging (MRI findings in 10 patients with subependimal giant cell astrocytoma (SGCA and tuberous sclerosis (TS. METHOD: Ten patients were retrospectively studied, presenting TS and histologically proven SGCA. Four patients were male and six female, with mean age 15.7 years. All patients underwent MRI, which was analyzed by two radiologists, final diagnosis was reached by consensus. The following findings were studied: topography, size, signal intensity on T1/T2-weighted images, contrast enhancement and associated findings. RESULTS: All patients presented a single lesion suggestive of SGCA, measuring between 1.5 cm and e 8 cm in the largest diameter. Eight lesions were found near the foramen of Monro and two in the body of the lateral ventricles. The tumors showed preferentially intermediate signal on T1 (70%, high signal on T2-weighted images (100%, with intense enhancement after contrast administration (100%. CONCLUSION: SGCA in patients with TS usually presents as a single lesion near the foramen of Monro, with intermediate signal on T1, high signal on T2-weighted images and intense contrast enhancement.

Ten Thousand Years of Solitude  

Energy Technology Data Exchange (ETDEWEB)

This report documents the authors work as an expert team advising the US Department of Energy on modes of inadvertent intrusion over the next 10,000 years into the Waste Isolation Pilot Project (WIPP) nuclear waste repository. Credible types of potential future accidental intrusion into the WIPP are estimated as a basis for creating warning markers to prevent inadvertent intrusion. A six-step process is used to structure possible scenarios for such intrusion, and it is concluded that the probability of inadvertent intrusion into the WIPP repository over the next ten thousand years lies between one and twenty-five percent. 3 figs., 5 tabs.

Stochastic variables in ten dimensions  

International Nuclear Information System (INIS)

A generator of infinitesimal Nicolai transformations is employed to reformulate their existence and polynomiality conditions. Their perturbative analysis in a four-dimensional chiral model reveals its complete variety of Nicolai mappings; however this model does not contain polynomial ones. By a reduction and truncation argument the ten-dimensional super-Yang-Mills theory is found to share this property. Hence, the list of stochastic gauge theories cannot be extended further to N=1, d=10; N=2, d=6; or N=4, d=4 super-Yang-Mills. (orig.)

Treating Ed A Medical Ethics Case Study  

Science.gov (United States)

Ed is dying. How should his wishes for medical treatment be carried out? As the case unfolds, students explore the rights and responsibilities of doctors, patients, and patient representatives regarding difficult medical decisions. Specifically, students consider the ramifications of Advance Directives and Durable Powers of Attorney. The case was written for an introductory biology course, but could easily be used in or modified for a human anatomy and physiology, introductory nursing, or medical ethics course.
