Evaluation of Bearing Capacity of Strip Footing Using Random Layers Concept
Authors: Kawa Marek , Łydżba Dariusz 
Published: November 2015

Abstract
The paper deals with evaluation of bearing capacity of strip foundation on random purely cohesive soil. The approach proposed combines random field theory in the form of random layers with classical limit analysis and Monte Carlo simulation. For given realization of random the bearing capacity of strip footing is evaluated by employing the kinematic approach of yield design theory. The results in the form of histograms for both bearing capacity of footing as well as optimal depth of failure mechanism are obtained for different thickness of random layers. For zero and infinite thickness of random layer the values of depth of failure mechanism as well as bearing capacity assessment are derived in a closed form. Finally based on a sequence of Monte Carlo simulations the bearing capacity of strip footing corresponding to a certain probability of failure is estimated. While the mean value of the foundation bearing capacity increases with the thickness of the random layers, the ultimate load corresponding to a certain probability of failure appears to be a decreasing function of random layers thickness.
Recognition of Anhydrite Intercalated Salt Deposit from Seismic Dataset Distorted by Noise
Authors: Kawalec-Latała Ewa 
Published: November 2015

Abstract
Acoustic inversion is useful to extract information from seismic data. Inhomogeneities of salt deposits should be predicted before the decision of underground storage location is made. The work concerns the possibility of detecting anhydrite intercalation in the rock salt from seismic dataset. The resolution strongly depends on signal to noise ratio. The synthetic pseudoacoustic impedance sections are generated for efficiency test of predictive and minimum entropy deconvolution process, when random noise distorts the seismic traces.
The power of cycling
Authors: Stannard Steve , Macdermaid Paul , Miller Matthew 
Published: November 2015

<p>One of the advantages of cycling exercise is that the rider is interfaced to a machine, and this exercise can be easily metered. Recent technological advances have made this metering easier and cheaper such that riders, sports scientists and coaches are able to record the external work done, and thus the net rate of mechanical work (power) during training and racing. Since external power is related to performance, the power requirements of competition can be observed and the training intensity can be prescribed. However, the ability to closely scrutinize power during training brings about a number of issues which need to be addressed. These issues include the accuracy and reliability of the meter, the relationship of the external work rate to the total physiological stress, and how training prescription through analysis by power may change the athlete-coach relationship. </p>

Published: November 2015

BACKGROUND:
The Cystic Fibrosis (CF) Foundation recommends patients attend clinic ≥4 times per year with 4 respiratory cultures and 2 pulmonary function tests (PFTs). However, nationally only 57.4% of patients met these guidelines in 2012. We used a quality improvement program with a goal of 75% of our patients meeting this care guideline by 2012.

METHODS:
A 2-stage program was started in 2011. Stage 1: education of patients/caregivers on importance of quarterly visits. Stage 2: quarterly tracking system of patient appointments. Data on clinic visits, respiratory cultures, and PFTs were collected from the CF registry from January 2009 through December 2013. Statistical process control charts were used to track improvements.

RESULTS:
The average number of clinic visits increased significantly from 4.6 ± 2.3 in 2009 to 6.3 ± 4.6 in 2013 (P &lt; .0001). The percentage of patients ages 6 through 18 completing a clinic visit, PFT, and respiratory culture per quarter increased significantly from 76.2% during 2009 to 86.4% in 2013. The percentage of patients completing ≥4 clinic visits with 4 respiratory cultures and 2 PFTs improved significantly from 47.5% in 2009 to 71.0% in 2013 (P &lt; .0001).

CONCLUSIONS:
A tracking system of patient appointments significantly improved adherence to the care guidelines better than education alone. The multiple-stage quality improvement program we implemented may be modifiable and able to be integrated in other CF centers or other multiple disciplinary chronic illness care centers.
Imagens de crianças: travessias do universo infantil
Authors: Leite César Donizetti Pereira , Chisté Bianca 
Published: November 2015

Este artigo apresenta o deslocamento do olhar sobre crianças e infância. Propõe se a refletir sobre esses lugares com as imagens produzidas por elas, com elas e com o que elas apresentam. As imagens, capturadas por crianças da pré-escola, no contexto da pesquisa intitulada “As crianças e suas experiências matemáticas: em busca do que atravessa o espelho”, compõem a metodologia, que se chamou de pesquisa como experiência. Refletir por meio das imagens produzidas por elas pode ser disparador para pensar a criança, a infância, e o que a partir dela toca, afeta, mobiliza o educador nesse movimento de travessias do universo infantil. Além disso, as imagens ajudam a pensar na possibilidade de uma formação docente que seja infantil, uma formação de professores da infância.
Mas o que é infância? – atravessamento de múltiplos olhares na formação de professores
Authors: Dornelles Leni Vieira , Marques Circe Mara 
Published: November 2015

O artigo trata das concepções de infâncias das estudantes de Pedagogia de uma instituição privada de ensino superior da região metropolitana de Porto Alegre. Problematizou-se na pesquisa outros modos de compreender as infâncias na formação de professores. Investigaram-se os deslocamentos e as resistências que atravessaram seus discursos sobre as infâncias, utilizando como metodologia de pesquisa uma bricolagem que faz uso de estratégia de leituras, vídeos, imagens, memórias pessoais, diário das estudantes e análise de suas discursividades para obtenção dos dados. O referencial teórico parte dos estudos de Bujes (2005), Dornelles (2010), Larrosa (2001), Marques (2013), dentre outros. Concluiu-se que os deslocamentos nas concepções de infância das alunas pesquisadas, não se deram de modo uniforme e linear, mas, diferentemente, mostraram avanços e retrocessos em seus modos de conceituar e entender as infâncias que compõem o cotidiano de seu trabalho. Entendeu-se a partir da investigação que é urgente investir “forças” no sentido de interromper o discurso moderno sobre infância no curso de Pedagogia e instigar as estudantes a produzirem “outros” modos de olhar, de pensar e lidar com as múltiplas infâncias que estão por aí.

Summary
Objective: Prospective characterization of hemostastatic variables, plasma lactate concentration, and inflammatory biomarkers in dogs with gastric dilatation-volvulus (GDV). Material and methods: Coagulation variables (platelets, prothrombin time [PT], activated partial thromboplastin time [aPTT], fibrinogen, antithrombin [AT], protein C [PC], protein S [PS], D-dimers), plasma lactate concentration and inflammatory biomarkers (C-reactive protein, white blood cell [WBC] count, lymphocyte and neutrophil numbers) were assessed in 20 dogs with GDV presented between 2011 and 2012. Blood was taken preoperatively and at days 1 and 3 postoperatively. The prognostic value of these variables before and after surgery was evaluated as well as the behavior of variables during the study. Results: Overall, 7/20 (35%) dogs did not survive; two dogs (29%) were euthanized during surgery due to severe gastric necrosis and 5 (71%) dogs after surgery due to sepsis and disseminated intravascular coagulopathy. Prior to surgery, median plasma lactate concentration was significantly (p = 0.01) lower in survivors (6.2 mmol/l, range 1.9–9.7 mmol/l) when compared to non-survivors (11.8 mmol/l, range 7.5–16.2 mmol/l). In dogs dying after surgery, significantly higher plasma lactate concentration, coagulation times and D-dimer concentration were present as well as lower fibrinogen concentration and activity of PC and AT compared to survivors. At discharge, activity of AT, PC and PS were markedly below the reference interval in 6/13 (46%), 11/13 (85%), and 8/13 (62%) dogs, respectively. Clinical relevance: Only lactate plasma concentration was of preoperative prognostic value. After surgery, severe abnormalities of coagulation variables, especially the endogenous anticoagulants were present in most of the dogs. The severity of the abnormalities was associated with survival.

Aim.To assess effectiveness and safety of a new rehabilitation method — interval hypoxia-hyperoxia training (IHHT) — in patients with chronic coronary heart disease (CCHD).Material and methods.This pilot study included 40 CCHD patients, Functional Class II–III (31 men and 9 women; mean age 61,7±7,7 years). The IHHT group (n=30) underwent 20 procedures (duration 40–50 minutes, 5 times a week), while the control group (n=10) underwent 20 similar placebo procedures. The REOXY device (AIMediqS.A., Luxemburg) was used for the creation of the gas mixtures with O2 content from 10% to 35–40%. At baseline and in the end of the treatment, individual hypoxia sensitivity was assessed in a 10-minute hypoxic test (HT). The IHHT procedure started with 5–7 minutes of mask inhalation of 12–11% О2, followed by 2–3 minutes of mask inhalation of 30% O2. The automatic switch between the gas mixtures followed the biological feedback principle; one procedure included 6–8 hypoxiahyperoxia cycles. Before and after the intervention phase, all participants underwent clinical and biochemical blood assay, rest ECG, submaximal treadmill test (time of the test, workload, and exercise capacity in metabolic equivalent units (MET)).Results.After the IHHT course, the main group demonstrated a significant increase in exercise capacity: test time increased by 34,1% (vs. —2,7% in controls), while exercise capacity (MET) increased by 15,8% (vs. 5,4% in controls), and the prevalence of angina attacks as the result of test termination significantly decreased. Improved exercise capacity was associated with a significant reduction in total cholesterol, plasma triglycerides, initially elevated blood pressure and resting heart rate, as well as with an elevated hypoxia tolerance threshold in the HT. In all participants, IHHT was well tolerated and free from adverse effects.Conclusion.The IHHT method increases exercise capacity in CCHDpatients, which is associated with lipid profile normalisation, blood pressure reduction, decreased number of angina attacks, and increased resistance to hypoxia.

The current status of obesity (O) as a global problem justifies the use of the term “obesity epidemic”, since the prevalence of O has increased substantially, in contrast to the decreasing prevalence of other risk factors (RFs).Aim.This analysis assessed the all-cause (AC) and cardiovascular disease (CVD) mortality levels by body mass index (BMI) in a middleaged Russian population.Material and methods.The present analysis included the data from seven studies performed by the State Research Centre for Preventive Medicine in 1975–2001. The total number of participants was 17821: 12887 men and 4934 women, aged 35–74 years. All participants were examined following the same protocol. The following parameters were analysed: socio-demographic and behavioural characteristics, lipid and carbohydrate metabolism disturbances, and clinical parameters. All participants were divided into seven categories by their BMI values: from BMI <21 kg/m 2 (first category) to BMI ≥36 kg/m 2 (sixth category). Results. There were positive associations between BMI and systolic blood pressure, diastolic blood pressure, triglycerides, and coronary heart disease presence. At the same time, BMI was negatively associated with smoking and excessive alcohol consumption. No associations were observed for BMI and left ventricular hypertrophy, heart blocks, or cholesterol levels. After adjustment for age, there was a U-shaped association between BMI and AC mortality. With the category “BMI <21 kg/m 2” as a reference group, mortality risk levels were decreasing for the second and third BMI categories, with an increased risk for the sixth category. In women, age-adjusted relative risk (RR) of AC mortality was only slightly lower than that in men. After additional adjustment for RFs and clinical parameters, RR of AC mortality was relatively similar across all BMI categories in both genders, without any significant differences compared to the reference group. Among lower BMI categories in men, RR of CVD mortality was close to RR for AC mortality. However, in higher BMI categories, the former was substantially higher than the latter. No similar patterns were registered for women.Conclusion.The observed tendency of elevated CVD risk in people with O suggests that particular attention should be paid to this risk factor. Adverse effects of O have also been demonstrated for people with arterial hypertension and diabetes mellitus. For the latter, its prevalence has substantially increased in Russia over the past years.

Aim. To assess the effects of moxonidine in terms of target blood pressure (BP) achievement; to identify potential additional benefits of moxonidine and its effects on bone metabolism and bone mineral density (BMD) in postmenopausal women with arterial hypertension (AH).Material and methods. The study included 48 postmenopausal women with Stage 1-2 AH, aged 57-71 years.Results. All participants were divided into two groups by the type of antihypertensive therapy: those receiving moxonidine and those receiving angiotensin-converting enzyme inhibitors / angiotensin receptor antagonists (ACEI/ARA). All women also received calcium and vitamin D. All participants had AH and osteopenia (both in the lumbar spine and proximal femur, according to the X-ray absorptiometry results). In the moxonidine group, BP levels remained within the target range 48 weeks later. There was a significant reduction in the levels of a bone resorption marker (p=0,041), while the dynamics of an osteopoetic marker was statistically non-significant (p=0,31). A tendency towards increasing BMD in lumbar spine and proximal femur was also observed (p=0,059 and p=0,068, respectively). In the ACEI/ARA group, BP levels also remained within the target range 48 weeks later. However, no significant changes in the levels of bone metabolism markers were registered. There was a tendency towards decreasing BMD in lumbar spine and proximal femur (p=0,052 and p=0,054, respectively).Conclusion. Moxonidine therapy was associated with a significant reduction in bone resorption activity, as demonstrated by the decrease in the concentration of a bone resorption marker, as well as with a tendency towards increasing BMD.

Aim. To reveal gender differences of clinical and functional parameters in postmyocardial infarction patients with chronic mitral regurgitation by data of coronary angiography Registry.Material and methods. Among 15283 patients of Coronary angiography Registry© evaluated from 1991 to 2012 we selected end assessed clinical and functional parameters of 350 men and 53 women with Q-wave myocardial infarction and moderate or severe mitral regurgitation and signs of scars detected by echocardiography.Results. Comparing to the men, women had lower hemoglobin level (135,5±11,3 vs 148,3±14,2 g/l, р<0,001) and rate of smokers (9,8 vs 62,6%, р<0,001). The prevalence of hypothyroidism (29,7 vs 9,6%, р=0,001) and severe MR (17,0 vs 9,1%, р=0,038) were higher in women. They had higher indexes of left atrium size (25,1±2,9 vs 23,7±3,2 mm/m2, р=0,008), left ventricular (LV) posterior wall thickness (6.0±0.7 vs 5,2±0,8 mm/m2, р<0,001), lower extent of LV wall motion abnormalities (28,7±14,7 vs 33,5±14,9%, р=0,036) and higher LV ejection fraction (47,3±8,2 vs 43,9±9,2%, р=0,013). The localization of myocardial scars and coronary stenosis did not differ between men and women. According to the results of multivariate analysis, female gender was independently associated with greater index of LV posterior wall thickness (OR 3,215; CI 1,781–5,804; р<0,001), hypothyroidism (OR 3,070; CI 0,994–9,483; р=0,050), greater body mass index (OR 1,17; CI 1,042–1,317; р=0,008), smoking (ОR 0,056; CI 0,013–0,244; р<0,001) and lower hemoglobin level (OR 0,927; CI 0,890–0,966; р<0,001).Conclusion. There are gender differences in clinical and functional parameters of postmyocardial infarction patients with chronic mitral regurgitation: more severe LV remodeling in women.

Aim. To study prevalence of various types of coronary heart disease (CHD) and their prognostic value in men and women older than 55 y.o.Material and methods. We used the data from selections of previously diagnosed persons. Totally 1875 included, with response at 64% level. All persons were questionnaired by the standard survey, that included social and demographic data, anamnesis, Rose questionnaire, behaviour. All patients underwent ECG 12 leads. ECG analysis was done with Minnesota conding system.Results. Every 4th male and every 3rd female revealed angina pectoris by the Rose questionnaire, and 9,5% men and 2,7% women had anamnesis of infarction. Ischemic changes on ECG more often in women — 15,6% vs. 10,0% (p<0,001); and infarction itself 2 times more often affects men — 7,1% vs. 3,2% (p<0,001). For men rhythm disorders are more common, i.e. left bundle branch block (p<0,03). Overall CHD prevalence does not significantly differ between genders and is 34,6% for men and 36,0% for women. The most severe forms in account of life threatening are rhythm disorders, ischemic changes and atrial fibrillation. At the same time, for cardiovascular mortality all parameters were significant, including heart failure. By the severity of prognosis all values are spread with the same manner as for general mortality.Conclusion. CHD in older age is highly prevalent and very diverse. In women less severe forms are marked comparing to men. Epidemiologic criteria for CHD on ECG can be regarded as diagnostic and as candidates for patients stratification by the mortality risk from cardiovascular diseases and from all causes.

Aim. To evaluate the influence of target BP achievement on clinical course and outcomes of pregnancy in pregnant women with arterial hypertension (AH).Material and methods. A cohort study with prospective cohort. Totally 300 pregnant women included; of those in to the 1st group 103 included with AH, who had not reached target BP; into the 2nd – 97 women with AH, who had reached target BP; control consisted of 100 women without AH. Women underwent clinical examination and observation, analysis of medical data, standard laboratory and instrumental investigation, genetic investigation by polymerase chain reaction.Results. Women who had not reached target BP pregnancy complicated more often with fetus development retardation and pre-eclampsy, and in pregancy outcomes there were preterm delivery and antenatal fetus death, newborns from this group had lower weight and height; also they had more often mutation of D-allele of ACE gene (I/D) and mutant C-allele of receptor 1 type angiotensine II gene (ATR11166 A/C) comparing to the group with achieved BP and with controls. By the result of logistic regression study the factor independently associated with total worse outcome, were premature deliveries in anamnesis - increase the risk almost 6 times (OR=5,93, 95% CI 1,83-19,2; p=0,003), pre-eclampsy during current preganancy – increases risk 3,7 times (OR=3,68, 95% CI 1,48-9,16; p=0,005), and target BP acievement (less than 140/90 mmHg) decreases the risk of total negative outcome 8 times (OR=0,12, 95% CI 0,05-0,28; p<0,001).Conclusion. Target BP achievement in pregnant women with AH might be an independent factor influencing the prevalence of obstetric complications and negative outcomes of pregnancy. A definite impact on target BP levels achievement make genetic polymorphisms of renin-angiotensin system genes.
