The article looks into the reasons underlying the outspread of the full-scale mechanism of banking regulation over U. S. investment banks. We analyze the effect of the Basel III standards on stress-resilience of investment banks and examine the role of U. S. investment banks in ensuring financial stability. Based on regression analysis we found that minimum capital adequacy standards of Basel III do not have negative effect on ROE of the U. S. investment banks that are G-SIB category-designate; however, additional capital requirements (Higher Loss Absorbency (HLA) surcharge) that depend on G-SIB’s systemic significance according to their bucket as per Financial Stability Board classification do have significant and negative effect on ROE in the post crisis period. Besides, leverage requirements that also depend on G-SIB’s systemic significance have a statistically significant effect on ROE.

This study presents an integrated analysis of cohesive bank-collapsed material transportation in a high-curvature channel with a non-cohesive riverbed. A numerical model was established to simulate the erosion and transportation of collapsed materials in a 180° U-bend channel after verification. The novel aspect of this study is that the quantities of the collapsed materials that transformed into suspended and bed loads were comprehensively analyzed. The results show that finer collapsed sediments were only transformed into suspended loads after being eroded, while the coarser particles transformed into both suspended loads and bed loads. When the flow charge was 30 L/s, the quantity of collapsed materials (S1 and S2) that transported downstream was smaller, and coarser materials transformed into suspended loads with a ratio of 88.12–99.86% and bed loads with a ratio of 11.18–0.14%. When the flow charge was 55 L/s, due to the greater shear stress, the quantity of collapsed materials (S1 and S2) that transported downstream was greater, and the ratio ranged from 46.65% to 49.88% and from 50.12% to 53.35%, respectively. This research provides theoretical and practical benefits that reveal the mechanisms of channel bend evolution.

Objective: despite the technologic advances in myocardial perfusion imaging, we keep using an uncomfortable and sometimes impracticable patient position - supine with arms raised above the head (U). The purpose of this study was to investigate whether perfusion and functional cardiac gated SPECT scan results of acquisition U are equivalent to another position modality: supine with arms down at the sides of the trunk (D). Methods and Results: we performed U acquisition and in sequence D acquisition in 120 patients (pts) using a one-day MPI (rest-gated/stress), with 99mTc-sestamibi (370 MBq and 1110 MBq). Images were processed by the iterative reconstruction method (OSEM). Rest (R) and stress (S) studies were scored using 17-segments model. Functional parameters (left ventricular ejection fraction, and volumes) were automatically obtained by the quantitative gated SPECT (QGS) program. According to the degree of stress defects observed in U study, the patients were categorized in two subgroups: normal (SSS ≤ 3 or < 5%) and abnormal (SSS>3 or ≥ 5%). Shoulder/back pain occurred in 23.3% of U patients and in 5% of D. No significant differences between U and D were found for SSS (p = 0.82) and SRS (p = 0.74) in normal group. In abnormal group, good correlation was found between U and D modes for SSS (Rho = 0.95, p = 0.0001) and SRS (Rho = 0.96 p = 0.0001), but the mean SSS (12.53 ± 7.54) and SRS (10.60 ± 7.08) values of D were significantly lower (p < 0.05) than SSS (13.43 ± 6.81) and SRS (11.33 ± 6.97) of U mode. Function measurements presented good correlations, except for end-diastolic volume (p = 0.0001). Conclusion: although D mode appears to be more comfortable and presented a good correlation with U values of SSS and SRS, in abnormal pts, the extent and severity of defects can be underestimated. Considering clinical implications of an accurate perfusion measurement, the acquisition with the arms down should be avoided.

The influence of the anatase titania nanoparticles (TiO2 NPs) content on the structural and optical properties of ZnO/TiO2 nanocomposites (ZTNCs) was demonstrated. The solution blending method was employed to prepare the ZTNCs with various ratios prior to their deposition onto glass substrates to form thin films. The X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM), and transmission electron microscope (TEM) techniques revealed that the crystallite size, grain size, and particle size of each TiO2 and ZnO NPs are almost equal. In addition to these techniques, Fourier transform infrared spectroscopy (FTIR) evidenced the homogeneity distribution of the TiO2 within the ZnO NPs. The structural properties of the wurtzite ZnO NPs such as crystallite size, lattice strain, dislocation density, bond length (L) of Zn–O, energy density (u), lattice stress (L S), Young’s modulus, and unit cell volume (V), can be tuned by incorporation of anatase TiO2 NPs in various content. Moreover, the optical properties of the wurtzite ZnO NPs such as absorbance, optical energy band gap (E g), energy gap tail (E u), steepness parameter (σ), and emission intensity can be tuned by incorporation of anatase TiO2 NPs in various contents. The E g and σ of ZnO NPs were decreased to reach at 2.41 eV and 0.0051, respectively, whereas the E u was increased to 4.598 eV upon the increment content of TiO2 NPs.

This technical study to predict the fatigue of the body structure made from material press submarine HY - 80. Because of the major operating expense that occurred on submarines that work is the hydrostatic load due to the nature of its operations. This resulted in hydrostatic load mains voltage (principal stress) which occurs when the submarine was on the surface and into the operational depth starting with Sarat depth (T) 5,5m to 50m and 100m. Events dives from the ocean surface to a depth of operational and back to the surface again, causing the submarine to change the burden of recurrent (repeated load) it contribute substantially to the structure of the material fatigue. Fatigue prediction calculation begins by modeling finite element method (FEM) in the press agency that assumed the form of a similar type submarine U-209 in the form of a hollow cylinder large bergading (web framed hollow cylindrical structure). Calculations carried out by applying the rules of fatigue damage accumulation Palgrem - Miner on S - N curve of materials HY - 80 based on the primary voltage data obtained from the FEM and the safety factor of 2.5. The assumption used is that the submarine has a screen of 120 days in a year. The results of this study show that the fatigue life of the structure of press submarine range 29 years. ABSTRAKKajian teknis ini untuk memprediksi kelelahan dari struktur badan tekan kapal selam berbahan material HY – 80. Karena beban operasional utama yang terjadi pada kapal selam yang bekerja adalah beban hidrostatik akibat sifat operasinya. Beban hidrostatik ini mengakibatkan tegangan utama (principal stress) dimana terjadi saat kapal selam masih dipermukaan dan masuk pada kedalaman operasional dimulai dengan kedalaman Sarat (T) 5,5m ke 50m dan 100m. Peristiwa penyelaman dari permukaan laut sampai kedalaman operasional dan kembali ke permukaan lagi, menyebabkan kapal selam mengalami perubahan beban yang berulang (repeated load) hal ini berkonstribusi cukup besar terhadap kelelahan material struktur tersebut. Perhitungan prediksi kelelahan ini dimulai dengan pemodelan metode elemen hingga (MEH) pada badan tekan yang diasumsikan dengan bentuk yang serupa kapal selam type U-209 dengan bentuk silinder berongga bergading besar (web framed cylindrical hollow structure). Perhitungan kelelahan dilakukan dengan mengaplikasikan aturan akumulasi kerusakan Palgrem – Miner pada S – N curve material HY – 80 berdasarkan data tegangan utama yang diperoleh dari MEH dan faktor keamanan 2,5. Asumsi yang dipakai adalah bahwa kapal selam memiliki 120 hari layar dalam setahun. Hasil studi ini menunjukkan bahwa umur kelelahan struktur badan tekan kapal selam berkisar 29 tahun.

An opened natural fracture (NF) intercepted by a pressurized hydro-fracture (HF) will be diverted in a new direction at the tips of the original NF and subsequently form a complex fracture network. However, a clear understanding of the diversion behavior of fracture networks in tight reservoirs with frictional NFs is lacking. By means of the extended finite element method(XFEM), this study investigates the diversion mechanisms of an opened NF intersected by an HF in naturally fractured reservoirs. The factors affecting the diversion behavior are intensively analyzed, such as the location of the NF, the horizontal principal stress difference, the intersection angle between HF and NF, and the viscosity of the fracturing fluid. The results show that for a constant length of NF (7 m): (1) the upper length of the diverted fracture (DF) decreases by about 2 m with a 2 m increment of the upper length of NF ( L u p p e r ), while the length of DF increases 9.06 m with the fluid viscosity increased by 99 mPa · s; (2) the deflection angle in the upper parts increases by 30.8° with the stress difference increased by 5 MPa, while the deflection angle increases by 61.2° with the intersection angle decreased by 30°. It is easier for the opened NF in lower parts than that in upper parts to be diverted away from its original direction. It finally diverts back to the preferred fracture plane (PFP) direction. The diversion mechanisms of the fracture network are the results of the combined action of all factors. This will provide new insight into the mechanisms of fracture network generation in tight reservoirs with NFs.

Purpose. The relationships of drinking, stress, life satisfaction, coping style, and antidepressant use to mental health were examined in a highly educated workforce. Design. This study used a one-time mail-out, mail-back cross-sectional survey design to examine the relationships of mental health with three kinds of stress (life events, work stress, home stress); two kinds of life satisfaction (work and home); use of avoidance coping; and antidepressant use. Setting. This study was conducted at a large worksite in northern California in which the workforce was comprised of predominantly highly educated employees. Subjects. Questionnaires were mailed to a random sample of 10% of 8567 employees, and 504 were completed and returned by participants (59%). Complete data were provided by 460 participants (53%). Measures. Respondents completed the Mental Health Index, the Alcohol Use Disorders Identification Test (AUDIT), and measures of coping style, work and home stress and satisfaction, stressful life events, and antidepressant use. Results. Mean Mental Health Index scores were at the 32nd percentile of the U.S. population-based norms, with low percentile values associated with worse mental health. Using multiple regression analysis, the factors examined in this study were significantly related to Mental Health Index scores as the dependent variable [ F(16, 443) = 27.41, p < .001, adjusted overall R2 = .48]. Poor mental health scores were significantly related to the following: age ( p < .05); screening positively for current harmful or hazardous drinking ( p < .05); having high levels of stress at work ( p < .05) or home ( p < .01); experiencing dissatisfaction with work ( p < .001) or home life ( p = .01); engaging in avoidance coping ( p < .001); and using antidepressants ( p < .001). Employees currently using antidepressants had significantly more outpatient medical and mental health visits, indicating higher health costs. Furthermore, mental health status was also significantly related to the interactions between several pairs of these variables: education and gender, age and job stress, home satisfaction and work stress, home satisfaction and avoidance coping, and home satisfaction and use of antidepressants. Conclusion. Mental health status was poorer on average in a highly educated workforce compared with general U S. norms. Most of the factors that were found to be associated with poorer mental health were ones that are potentially modifiable, such as experiencing more stress and less satisfaction in work and home life and engaging in current hazardous or harmful drinking. The findings that mental health is worse among individual employees who exhibit combinations of these factors suggest that we need to better understand possible effects of these factors in the context of one another. As interpretation of these results may be limited by the single worksite that participated in this study, future research should re-examine these relationships in other worksites varying from this one in geography and demographic characteristics.

Introduction. Pain is classified as acute and chronic. Acute pain implies a painful condition with a rapid onset or of a short course, whereas chronic pain is referred to as a painful condition persisting beyond the normal time of healing. Chronic low back pain has also been correlated with stress-induced inflammation. Psychological distress aggravates pain symptoms and pain induces a stress response in the body by releasing cortisol from the adrenal cortex. The aim of the study. To investigate differences in levels of anxiety, depression, and cortisol blood concentration in patients with acute and chronic vertebral-sacral pain syndrome. Our main goal was to encrease our understanding of the development and persistence of acute and chronic back pain, define risk factors and improve treatment strategies for the patients. Materials and methods: We studied cortisol levels in blood plasma, levels of anxiety and depression in patients with back pain and LV-SI intravertebral disk herniation. The group under investigation included 125 patients, including 65 patients with acute, and 60 with chronic pain syndrome. A Visual Analogue Scale (VAS) was used to measure the patient`s pain assessment. Spielbergʼs anxiety test is designed to assess reactive and personal anxiety. Personal anxiety characterizes the degree of a person’s anxiety and emotional tension due to the action of stress factors in general. Reactive anxiety is a patient’s personal condition, which characterizes the degree of his anxiety, and emotional tension in response to the action of a stress factor. The Beck’s Depression Symptoms Questionnaire (BDSQ) includes 21 item, self-report rating inventory that measures characteristic attitudes and symptoms of depression. Results. We found no significant difference according to VAS between groups, at the time of hospitalization, patients in the acute pain group evaluated their pain as 7.15 ± 1.17 points, while in the chronic pain group it was estimated as 6.08 ± 0.96 points (p-value more than 0.05). The concentration of cortisol in blood plasma in the acute pain group patients was 313.3 ± 87.7 mmol/l, and in the chronic pain group – 450.7 ± 121.9 mmol/l, the difference between the groups was insignificant (p-value more than 0.05). The evaluation according to Spielbergʼs anxiety test demonstrated high anxiety levels at the time of examination: in the acute pain group reactive anxiety corresponded to 40.4 ± 12.6 points, in the chronic pain group the same index was 39.5 ± 11.3. Personal anxiety in the group of acute pain was 32.3 ± 13.6, in the group of chronic pain – 41.3 ± 9.7. According to Beck’s Depression Symptoms Questionnaire before the beginning of treatment average score in the acute pain group was estimated as 6.8 ± 1.1 points, while in the chronic pain group this index corresponded to 9.8 ± 0.8 points (probable difference between groups p-value less than 0.05). Comparisons of cortisol concentrations between groups of patients with different levels of pain, anxiety, and depression demonstrated no significant differences. However, cortisol level was higher in the acute pain group among patients who rated their pain syndrome as ʺsevere painʺ (6-7 points according to VAS) (280.2 ± 77.8 mmol/l in the group of acute pain, and 515.0 ± 80.1 mmol/l in the group of chronic pain), as well as among patients with mild depressive symptoms (393.5 ± 19.5 mmol/l in the group with an acute pain compared to 553.1± 68.0 mmol/l in the group with chronic pain syndrome). Conclusions. The study demonstrates differences in pain perception and assessment in patients that suffer from acute and chronic back pain. A high level of personal and reactive anxiety was found among participants. A higher level of depressive symptoms, as well as the disturbances in the diurnal fluctuations of cortisol were detected in the chronic pain group patients.

Abstract Background: Platelet hyperreactivity involves increased secretion of their granule content which promotes platelet aggregation and thrombosis. Platelet hyperreactivity is observed in conditions such as diabetes mellitus and is associated with decreased cardioprotective effect from antiplatelet agents in this patient group. Diabetes is associated with increased endoplasmic reticulum (ER) stress from hyperglycemia and hyperlipidemia. Protein disulphide isomerase 6 (PDIA6) is an endoplasmic reticulum protein which folds nascent proteins by reduction and oxidation of their disulphide bonds. PDIA6 has been shown to inhibit downstream ER stress pathways by inhibiting the phosphorylation of IRE-1 in fibroblasts (Eletto, Mol Cell, 2014). We hypothesized that ER stress pathways are functional in platelets and that PDIA6 may inhibit ER stress pathways leading to platelet secretion. Methods: We generated conditional PDIA6 knockout mice (PF4Cre+ Pdia6 fl/fl) (CKO) in the megakaryocyte/platelet lineage by CRISPR-Cas9 technology (Fig.1A). Megakaryopoiesis and haemostasis was assessed by bone marrow histology, coagulation assays, platelet aggregation and tail bleeding studies. We induced ER stress of purified platelets by incubation with thapsigargin and tunicamycin. Activation of the PERK and IRE1 pathways was measured by Western blot. Thrombosis was assessed in vitro by microfluidic devices and in vivo by electrolytic injury of the carotid artery. Results: PDIA6 CKO mice displayed a mild macrothrombocytopenia: the mean (+/-SD) platelet count in Pf4Cre+/Pdia6fl/fl was 775 +/- 98 x10 3/ul compared with 874 +/- 55 x10 3/ul in Pdia6fl/fl (p<0.005). The median platelet volume was 6.3 fL in Pf4Cre+/Pdia6fl/fl compared with 5.7 fL in Pdia6fl/fl (p<0.005). Megakaryopoiesis was normal at baseline. However, PDIA6 CKO mice showed significant upregulation of intracellular platelet PDIs including PDIA1, PDIA3 and PDIA4. PDIA6 deficient platelets displayed significant increase of disulphide reductase activity and the generation of free thiols on the platelet surface. Activation of the PERK and IRE-1 pathway at baseline and after induction of ER stress was increased in PDIA6 deficient platelets (Figure 1B, C). There was striking hypersecretion of PDIA1 (Figure 1D) and α-granule proteins (Figure 1E, F) in response to shear and stimulation with thrombin. PDIA6 CKO mice displayed a prothrombotic phenotype with increased platelet adhesion to fibrinogen under shear (500 s-1) and decreased time to carotid artery occlusion (mean+/SD: 10.8 +/-3.2 min in Pf4Cre+/Pdia6fl/fl compared with 15.3 +/-5.2 min in Pdia6fl/fl, n=8-10, p<0.05). Conclusion: We have identified a role for platelet PDIA6 in attenuating platelet ER stress and secretion. This opens avenues for further study into the role of platelet PDIs in conditions with increased ER stress, such as obesity and diabetes.

Xenobiotic biotransformation process and its capacity is crucial for xenobiotic chemicals elimination that may cause damage toward cell structures. The effectiveness of the enzymes included in this process depends on the gene variants that encodes them. The aim of this work was to compare certain polymorphisms of selected genes between cases and control groups. Studied polymorphisms were null genotypes of the glutathione S-transferase gene M1 and T1 and the insertion of TA dinucleotide in the promotor region of UDP-glucuronosyl transferase 1A1. The number of cases group was six included patients with colorectal, lung, prostate, breast, pancreatic and head and neck cancer. Total number of analysed individuals was 1 118 for cancer cases and 470 for healthy controls. The control group was divided into two groups, the first one was called general and the second one was called special included healthy individuals with no cancer history in their closest family members. Gilbert syndrome (GS) is caused by homozygous insertion of the TA dinucleotide in the TATA box of the gene UGT1A1 and it causes elevated bilirubin levels. Bilirubin is a potent antioxidant in human body, so the aim was to attest its protective effect toward cancer. We expected lower frequency of GS as a protective factor in the cases groups compared with controls. This hypothesis was confirmed in the breast cancer group (GS frequency 10,0 %) and pancreatic cancer group (GS frequency 11,1 %). In the general and special control groups the frequency of GS was 16,0 % and 15,4 % respectively. Although the other case groups show lower frequency of GS, the results weren´t statistically significant. Null GSTM1 genotype was observed with 50,4 % frequency in the general control groups and with 55,3 % frequency in the special control group. Neither the one of the cases groups hasn´t showed significantly lower percentage of null genotype. Despite expectation we observed statistically significant lower frequency of null genotype in the group of lung and pancreatic cancer group (37,4 % and 39,3 % respectively). According to this study, we can say that the lack of glutathione S-transferase M1 activity is not a risk factor for cancer development. Null genotype of GSTT1 wasn´t identified in both control groups at all. In case groups of breast and prostate cancer, there was only one individual carrying the null GSTT1 genotype. Statistically significant higher frequency of this polymorphism was observed in patients with colorectal cancer (9,7 %), lung cancer (17,2 %), pancreatic cancer (3,0 %) and head and neck cancer (15,9 %). In these groups the lack of glutathion S-transferase T1 activity might be considered as risk factor for cancer development. Nevertheless, for further verification it needs to take more investigation in this field, especially enlarge the number of patient in the case groups of head and neck, lung and pancreatic cancer.

Variables predicting the effects of surgery in patients with low back pain Abstract The theoretical part of the thesis summarizes the knowledge about pain and its types, especially chronic pain. Than we focus on low back pain and currently used approaches in the treatment of this syndrome. In this work we summarize the influence of central sensitization and adverse life experineces and posttraumatic stress disorder on pain (especially low back pain). In the practical part, we investigated the effect of central sensitization and adverse life events and posttraumatic stress disroder on the effect of spinal surgery in low back region. The results were obtained using Central Sensitization Inventory (CSI), PTSD Cecklist dor DSM-5 (PCL- 5) a Life Event Checklist (LEC-5 Standard), Short Form 36 Helth Survey Questionnaire (SF- 36), NASS Lumbar Spine Questionnaire. The obtained data were statistically evaluated and processed. Higher scores of CSI and LEC-5 (more adverse life events) were both statistically significantly correlated with worse low back surgery outcomes. At the same time, a statistically significant relationship between PCL-5 (checklist of PTSD symptoms) and CSI was confirmed.

The submitted thesis deals with coping strategies for people treated with depressive disorders. It deals with the context of the experience of depression and the choice of coping strategies. The aim of this work is to find out whether there is a difference in the selection and use of coping strategies in people diagnosed with depression compared to non-psychiatric population. In the literary review, attention is paid to the depressive disorder, its description and symptoms. Other topics are the definition and theories of stress, followed by the stress management strategies. The empirical part has quantitative research using a questionnaire survey. SVF-78 and BDI-II questionnaires were used as methodological tools. The aim of the practical part was to find out whether there is a difference in the use of coping strategies in people with a diagnosis of depression compared to the general population and if so, what defensive strategies are prevalent or, on the contrary, are used statistically less. Research has demonstrated the specifics of using coping strategies in people with a diagnosis of depression. People with a diagnosis of depression frequently use significantly more negative coping strategies. There was no difference in use between the two groups in the search for a social support strategy...

Title: Experiance with joga for tennis coaches Objectives of work: The aim of my thesis is to analyze the possitive effects of yoga on the mental and physical health of tennis players. The data is gained by quality data collection methods. The secondary objective is, on the basis of information obtained from short interviews with coaches, to create a theoretical model of categorization. Method: In this thesis we used the method of interview and narrative interview. The data collected from the interviews, was used to create a theoretical model of categorization. A method of narrative interview with elements of the interview was used as a key method of collecting data from selected subjects. Results: Following numerous interviews with various subjets including coaches and trainers, I have come to the conclution, that yoga has a positive effect on the mental and physical health of tennis players. The main effects of yoga include: increased confidence and concentration on the court, accelerated healing, reduced pain in the spine (notibly in lumbar region), therefore increasing the flexibility of joints and improving the performance of players. In terms of categorization on the effects of yoga, both in mental and physical health of tennis players, I classified the effects into two major categories: the...

1. Abstract Pheochromocytoma/ paraganglioma (FEO/PGL) may be developed on the basis of an inherited genetic mutation of different genes. They are associated with a high risk of developing of secondary hypertension, organ damage and metastatic disease that can be fatal. The aim was to focus on the possibility of genetic testing in patients with FEO/PGL, especially in patients with malignant tumors. The issue FEO/PGL, however, concerns not only the examination and assessment of risks arising therefrom, as well as other therapies and monitoring, including appropriate recommendations for clinical practice. We demonstrated a 20% incidence of cardiovascular (CV) complications before determining the final diagnosis of FEO/PGL, mainly arrhythmic, followed by complications of myocardial ischemia and accentuate atherosclerosis. Elevated levels of vitamin C and decreased levels of malondialdehyde (MDA) following the successful removal of the tumor demonstrated reduction of oxidative stress postoperatively. We found that early postoperative testing of levels of plasma metanephrines to confirm the success of surgical removal of FEO/PGL is already possible, since there was no significant correlation between plasma levels of metanephrines and postoperative examination interval.

Badania przedstawione w niniejszej pracy były finansowane z grantu Narodowego Centrum Nauki, N 304 280840, przyznanego J. R. E. Taylorowi.W niniejszej rozprawie testowałem hipotezę, że stres oksydacyjny, uwidaczniający się w oksydacyjnych uszkodzeniach tkanek, jest bezpośrednim fizjologicznym kosztem rozrodu. Obiektem badań były samice nornicy rudej Myodes glareolus. W pierwszym eksperymencie samice mogły urodzić jeden lub dwa naturalne mioty. Miałem także osobniki nie rozmnażające się. Oznaczyłem uszkodzenia oksydacyjne lipidów i białek w różnych tkankach. Wbrew oczekiwaniom, uszkodzenia te albo nie różniły się między samicami z grup reprodukcyjnych, albo były niższe u samic rozmnażających się. W drugim eksperymencie różnicowałem więc wysiłek samic poprzez dodawanie dwóch młodych do oryginalnego miotu lub zmniejszałem go do dwóch młodych w kolejnych czterech miotach rodzonych przez samice. Wbrew przewidywaniom uszkodzenia u samic rozmnażających się nie różniły się od uszkodzeń samic nie rozmnażanych lub były od nich niższe. Takie same oznaczenia uszkodzeń oksydacyjnych, wykonałem u samic nornicy bezpośrednio po odłowieniu z naturalnego środowiska, przed i po okresie rozrodu. Ogólnie samice po reprodukcji najczęściej albo się nie różniły pod względem poziomu stresu oksydacyjnego od osobników przed reprodukcją, albo poziom ten był nawet niższy. Podsumowując moje wyniki falsyfikują hipotezę, że stres oksydacyjny jest mechanizmem odpowiedzialnym za powstawanie kompromisów pomiędzy aktualnym inwestowaniem energii w rozród a przeżywalnością i przyszłym sukcesem reprodukcyjnym.
I tested the hypothesis that oxidative stress is the proximate mechanism of reproduction costs, using bank vole Myodes glareolus as a model species. In the first experiment, the oxidative damage to lipids and proteins was measured in breeding females after rearing one and two litters, and in non-breeding females. Surprisingly, the level of oxidative damage did not differ between females from different reproductive treatments or was lower in breeding than in non-breeding females. In the sceond experiment, I experimentally manipulated the reproductive effort of females from selected and control lines by reducing or enlarging the original litter size in four consecutive litters. The level of oxidative damage to tissues in breeding voles did not differ from non-breeding individuals or was even lower. I also measured the level of the same oxidative stress markers in bank vole females from a free-living population. In general, females afterreproduction did not differ in the level of oxidative stress form females before reproduction, and in a few cases the level was even lower. In summary, my results undermine the hypothesis that oxidative stress is the key proximate mechanism underlying the trade-off between the current investment in reproduction and future survival or reproductive success.

Abstract Until recently, bank cost studies focused almost exclusively on scale and product mix (scope) economies. While this has been useful, a potentially more important dimension of bank cost economies appears to be differences in efficiency. Recent studies have estimated inefficiencies of 20 percent or more of costs, even for banks of similar scale and product mix. These inefficiencies appear to dominate scale and product mix effects, which usually average 5 percent or less. Our purposes in this chapter are twofold. First, we apply two methods of ef ficiency measurement that have been employed in extant efficiency literature and contrast the results across methodologies. Specifically, we compare the stochastic econometric frontier approach, first proposed by Aigner, Lovell, and Schmidt (1977), Meeusen and van den Broeck (1977), and Battese and Corra (1977), with the thick frontier approach of Berger and Humphrey (1991, 1992a). These methods are applied to a panel data set of 683 U.S. banks with over $100 million in assets in states that allow branch banking that were continuously in existence during 1977 to 1988. As these banks account for two-thirds of total banking assets, and all U.S. states allow some form of branching as of August 1991, our results may be considered reasonably representative of the industry as a whole.

East Berlin. August 13, 1961. As the sun peeks over the horizon on this beautiful Sunday morning, most East Berliners sleep on, but some rise for work; a few thousand of them are Grenzgänger, who cross town—quite legally—to work in the “other” Berlin, mostly as hotel and restaurant employees and in other service jobs made lucrative by the uneven exchange rate. Each day they make the trip to West Berlin—by foot, by bicycle, by S-Bahn and U-Bahn, showing their DDR identity cards and special work permits to the bored Grepos (Grenzpolizei, border police) stationed at the gates. But this morning the Grepos are not bored; today, as the would-be commuters discover as they reach streets and subway stations along the East Berlin border, no Grenzgänger will cross. “Die Grenze ist geschlossen!” people scream to each other in the early-morning stillness. “The border is closed!” No subway cars are running westward; Grepos guard the U-Bahn tunnels to prevent subway commuters from fleeing to the West on foot; Vopos turn back Grenzgänger at every checkpoint. The SED has apparently found a way to secure its future and halt the flight of DDR and skilled labor—by walling them in. WHO HAS THE YOUTH, HAS THE FUTURE! As the Grenzgänger stumble home and the DDR capital—“die Hauptstadt der DDR”—awakens to the nightmare, it is as if a tremendous howl—the anguished wail of cornered, trapped, desperate animals—has gone up throughout East Berlin— as it soon will over the DDR. For almost a decade, East Germany’s 600-mile border has been sealed by barbed wire and 12-foot electrified fencing; just inside the fence is a strip of land about 50 yards wide that is cleared of brush, dotted with mines, and covered by machine guns in high watchtowers. And so, most aspiring refugees make their way to East Berlin, where many of the streets and subway stations along the city border are guarded casually, if at all.

<em>Abstract</em>.—Habitat for striped bass <em>Morone saxatilis</em>, hybrid striped bass, salmonids, and other coolwater and coldwater fishes can be limiting in stratified reservoirs during summer and early autumn as surface water temperatures increase above tolerable ranges and deeper waters are depleted of dissolved oxygen (DO). Usable habitat can be increased in these reservoirs using oxygen diffusers to increase DO concentrations in the cooler, deeper waters. Several oxygen diffuser systems are currently in operation. Some of the systems were originally designed to increase DO in hydropower reservoir releases, but have also created fish habitat as a result of the diffuser system’s efficient oxygen transfer capabilities in the reservoir. Several other systems are operated to improve water quality in the reservoir for water supply, and two systems have specific fish habitat maintenance goals. Improvements in DO for fish have been obtained at Calaveras Reservoir, California by the San Francisco Public Utility Commission, and fish studies at this reservoir are currently underway. In North Twin Lake, Washington, the Colville Confederated Tribes and Washington State University have documented improved trout habitat and reduced sulfide concentrations. Oxygenation of cool, deep water is now a proven technology that can alleviate summertime thermal and oxygen stress on striped bass and hybrid striped bass and can minimize habitat-related mortalities. The technology is being implemented specifically for striped bass with a large installation in J. Strom Thurmond Reservoir, South Carolina, for the Savannah District of the U. S. Army Corps of Engineers.

Texto completoResumen
ABSTRACT Öksüt is a breccia-hosted high-sulfidation epithermal gold-copper deposit, situated within the Develidağ Volcanic Complex in south-central Anatolia. The volcanic complex, exposed on the northern edge of the Tauride range, is largely made up of late Miocene andesitic to dacitic porphyries, covered by a succession of Pliocene basalts and basaltic andesites. A series of N-S- to NNW-trending faults of the regional central Anatolian fault zone partly cut and border the volcanic complex to the east and west. Mineralization at Öksüt follows a predominant north-northwest trend that correlates well with the regional stress regime. The bulk of the mineralization occurs in two domains, the Keltepe and Güneytepe orebodies, where steeply dipping and pervasively supergene oxidized breccia zones exploited funnel-shaped diatreme conduits within pyroxene andesite porphyry. Emplacement of these phreatomagmatic breccias was largely controlled by vertical to subvertical faults with dominant normal-slip components. Mineralized breccias comprise a central zone of residual vuggy to massive silica alteration, laterally and vertically grading into zones of quartz-alunite and quartz-alunite-clay alteration. These silica-altered breccias contain relatively high gold grades, whereas significant mineralization was also encountered in quartz-alunite-clay alteration. In the oxide zone, gold occurs in native form, whereas in the hypogene zone it occurs both as native gold or within pyrite-enargite accompanied by marcasite, and rare chalcopyrite and tetrahedrite. To the west of Keltepe and in Güneytepe, at depth, the altered and mineralized breccias pass into barren zones of argillic and then into biotite-magnetite ± K-feldspar ± anhdyrite alteration, the latter typical of porphyry-type systems. Sporadic zones of calc-silicate alteration, represented by grossularite, diopside, and vesuvianite, are also present. Three 40Ar/39Ar ages obtained from alunite and illite range between 5.7 to 5.5 Ma and are concordant with previously reported U-Pb and 40Ar/39Ar ages (~6–5.5 Ma) from host pyroxene andesite porphyry. This suggests that high-sulfidation alteration and mineralization developed contemporaneously with postsubduction magmatism at the Develidağ Volcanic Complex, in relationship to regional E-W-directed extension that commenced at ~6 Ma. Our new ages also confirm Öksüt as the youngest epithermal gold deposit discovered to date in Anatolia, and possibly in the entire Western Tethyan metallogenic belt. The topographic prominence of the volcanic edifice combined with high permeability of the breccias favored deep supergene sulfide oxidation, thereby rendering Öksüt economically viable. Gold encapsulated in hypogene sulfides was liberated during the oxidation, whereas the copper was leached to produce a discontinuous chalcocite- and covellite-dominated enrichment zone, up to 50 m thick, at the base of oxidation.

Abstract Recently NRL researchers have embarked on a basic research effort “Tuning Giant Magnetoelectric Properties in Phase Transformation Multiferroics” focused on multifunctional materials for energy transduction and conversion. Multiferroic materials combine at least two coupled ferroic properties and are used in multiple applications including magnetic field sensors, energy harvesting devices, non-volatile memory and antennas. There are very few single phase multiferroic materials, and they normally have relatively low magnetoelectric (ME) coupling coefficient. In contrast, engineered materials such as ME composites fabricated from piezoelectric and magnetostrictive materials can show multiple orders of magnitudes increase in the ME coupling coefficient. The optimal design of ME composites would lead to conditions of maximum response (strain, induced voltage, or field) with minimum applied electric or magnetic fields, providing advanced materials for transduction, sensing, energy harvesting and other applications. That is why NRL researchers are working on piezoelectric materials with enhanced properties due to a phase transformation that would minimize the stimuli needed to achieve large strains. Key to the successful design and fabrication of ME composites is an understanding of interface characteristics as well as individual material components. In this paper we will review the current status of work at NRL on engineered multiferroic composites comprised of piezoelectric and magnetostrictive materials coupled through strain. There are still many open questions about the interfacial properties as well as the individual component materials. Details will be presented from recent work on material characterization under repetitive cycling, interface characteristics, and stress/electric/thermal effects on driving the phase transition in a relaxor ferroelectric single crystal.

Texto completoResumen
To investigate the effect of cooling on the thermo-mechanical behavior of U-10Mo fuel plate during shutdown step, Finite Element (FE) analysis was performed on the plate L1P756 from RERTR-12 experiments [1]. Changes in cooling rates were simulated by varying the coolant velocity on the two sides of the plate. Since coolant velocity was directly related to heat transfer coefficient (hc), different cooling velocities have been implemented by changing heat transfer coefficient corresponding to coolant velocity ranging from 10% to 200% of the baseline coolant velocity. Also, this study investigated the effect of strain rate on residual stresses of the mini-plates, which may be caused by the cooling rate. From numerical analysis results, it was found that cooling time increases as the coolant velocity decreases. It was observed that the cooling time is seven times longer if the coolant velocity is reduced 90%. A plate with two times faster coolant than the baseline reduced the cooling time by half of the original cooling time. As the cooling proceeded, von Mises stress was being increased in the plate and the highest stress at a certain time during the shutdown period was observed in the plate with the fastest coolant flow. However, no difference in residual stress was found at all different cooling rates at the end of the shutdown step. For strain rate effect analysis, the maximum strain rate was calculated to be 3 s−1 as soon as the cooling was started and the strain rate drastically decreased close to zero. The change of strain rate in time was found the same in all cases with different cooling rates. Therefore, it turned out that the cooling rate did not affect the residual stress of the cladding considered in this study.

Texto completoResumen
PCC is used empirically for its factor VIII (FVIII) bypassing activity in hemophiliacs with inhibitors to FVIII. The effect of of PCC on plasma coagulation tests is variable and is not predictive of clinical response. We are testing the hypothesis that bypass activity is expressed locally at the vessel wall, which functions as a procoagulant surface at times of hemostatic stress. Monolayer cultures of umbilical vein endothelial cells (EC) were incubated for 1 hour with commerical PCC (1 u/ml), and then extensively washed to remove fluid phase PCC components. Ellagic acid-activated PTT determinations were then done over the treated monolayers using plasma deficient in FVIII (<1 u/ml). PTTs over EC pre-treated with PCC were shorter than PTTs with control EC or EC pre-treated with commercial FVIII concentrate (control 101 s, PCC treated 57.7 s, FVIII treated 84 s, means of n=3). Similar results were obtained using non-activated PTTs and with adult saphenous vein EC. The bypass effect of PCC was dose-related:non-activated PTTs were 172 s (control),134 s (PCC 0.1 u/ml),and 107 s (PCC 1 u/ml). Pre-treatment of EC with cycloheximide shortened the PTT of FVIII deficient plasma, presumably due to impaired expression of endogenous anticoagulant activity.Subsequent incubation of cycloheximide pre-treated EC with PCC still provided FVIII bypass activity. In contrast, FVIII consistently failed to shorten the PTT using FVIII deficient plasma added to cycloheximide pre-treated EC. Thfe ability of PCC to bypass the FVIII defect was not impaired using paraformaldehyde 1fixed in place of live EC, but was reduced or abolished if the ECwere incubated with PCC at 4° instead of 37°.The putative FVIII bypassing component present in PCC may therefore express its activity only upon interacting with EC at sites of vascular interruption. Further studies using purified reagents will be necessary to identify the responsible substance(s). These observations may help explain the discrepancy between the clinical. efficacy of PCC and its inconsistent effect on plasma coagulation tests.

The purpose of this study is to make clear effect of material degradation on creep and creep-fatigue properties of a weldment. Materials used in this study were a weldment of a boiler super header operated for about 200,000 hours (U weld joint) and a simulated as-received weldment (S weld joint). In the U weld joint, although creep cavities were not observed at all, significant coarsening of carbide precipitation and low dense dislocation structure were observed at all locations in the weldment compared with microstructure of the S weld joint. Creep rupture time of the U weld joint is shorter than that of the S weld joint at higher stress region, while the discrepancy of the rupture strength tends to disappear as stress level becomes lower. Strain controlled creep-fatigue tests with 1 hour and 10 hours strain hold time at the maximum tensile strain were performed at strain range of 0.3% and 0.5% on S and U weld joints. No difference of failure life between materials was observed. Reduction in failure life by introducing strain hold period becomes larger as decreasing strain range level indicating that creep-fatigue interaction is enhanced under lower strain range. Based on the nonlinear damage accumulation model, a simplified creep-fatigue life prediction method of weldments under creep-fatigue loading conditions was proposed. It was demonstrated that failure lives under the long-term creep-fatigue conditions were well predicted by the simplified prediction method.

The U. S. Nuclear Regulatory Commission and the Electric Power Research Institute, cooperating under the auspices of a memorandum of understanding, conducted a double-blind round robin study for prediction of weld residual stress in a full-scale pressurizer surge line mockup. This work is the latest in a series of studies aimed at understanding and reducing uncertainty in the numerical prediction of weld residual stress. The round robin study involved both measurements and modeling. The measurements included deep hole drilling and contour method. Ten international participants submitted finite element modeling results to the study. This paper summarizes the mockup design, the modeling problem statement, and the measurement and modeling results.

Abstract: Risk management is an indispensable part of the financial market and banking sector and consists of the identification of various forms of risk to which banking operations are exposed. Accelerated and constant market development, globalization and internationalization of the market and new technologies bring new challenges but also risks. Risk management in today's dynamic environment brings with it numerous obstacles but also poses new challenges and opportunities for companies, which implies the establishment of appropriate corporate management and risk culture. Through an adequate and appropriate risk management system tasks and responsibilities of the supervisory and management body and senior management, the system of internal controls, control functions, organizational chart and tasks of individual organizational parts and functions are defined. The banking sector and banking operations are exposed to many risks where several risks occur simultaneously, there is no risk that is only one or placement that carries only one risk, while an additional problem that the bank faces is the quantification of risk. Identifying, measuring, assessing, managing, monitoring and reporting on risks implies defining a risk management strategy which defines the basic guidelines for medium-term risk assumption and the development of risk management and control systems. The risk management strategy is aimed at defining a set of basic standards for sustainable and effective management and control of all identified risks to which the bank is or could be exposed in its operations, taking into account the quality of implementation and compliance with business plans and objectives. The aim of this paper is to present the potential risks that arise in regular banking operations and to show banks risk management system in order to increase the quality of bank operations. Sažetak: Upravljanje rizicima neizostavan je dio financijskog tržišta odnosno bankarskog sektora, a sastoji se od identifikacije različitih oblika rizika kojim je izloženo bankarsko poslovanje. Ubrzani i konstantni razvoj tržišta, globalizacija i internacionalizacija tržišta, nove tehnologije sa sobom nose nove izazove ali rizike. Upravljanje rizicima u današnjem dinamičnom okruženju nosi sa sobom brojne prepreke ali i stavlja pred poduzeća nove izazove i prilike što podrazumijeva uspostavu odgovarajućeg korporativnog upravljanja i kulture rizika. Upravo kroz adekvatan i odgovarajući sustav upravljanja rizicima definiraju se uloge, zadaci i odgovornost nadzornog i upravljačkog tijela i višeg rukovodstva, sustav unutarnjih kontrola, kontrolne funkcije, organizacijska shema i poslovi pojedinih organizacijskih dijelova i funkcija. Bankarski sektor i bankarsko poslovanje izloženo je mnogobrojnim rizicima gdje se nekoliko rizika javlja istovremeno, ne postoji rizik koji je samo jedan ili plasman koji sa sobom nosi samo jedan rizik dok je dodatni problem s kojim se banka susreće kvantifikacija rizika. Utvrđivanje, mjerenje, procjenjivanje, ovladavanje, praćenje i izvještavanje o rizicima podrazumijeva definiranje strategije upravljanja rizicima kojom se definiraju osnovne smjernice za srednjoročno preuzimanje rizika te razvoj sustava upravljanja i kontrole rizicika. Strategije upravljanja rizicima usmjerena je na definiranje skupa osnovnih standarda za održivo i učinkovito upravljanje i kontrolu svih identificiranih rizika kojima banka je ili bi mogla biti izložena u svojem poslovanju, vodeći računa o kvaliteti primjene i usklađenosti istih s poslovnim planovima i ciljevima organizacije. Cilj ovog rada je izložiti potencijalne rizike koji se javljaju u redovnom bankarskom poslovanju i prikazati načine na koje se banka nosi s njima, odnosno upravljanja rizicima u funkciji povećanja kvalitete poslovanja.

En ASME 2007 26th International Conference on Offshore Mechanics and Arctic Engineering. ASMEDC, 2007. http://dx.doi.org/10.1115/omae2007-29194.
Texto completoResumen
Hydrogen influenced cohesive zone elements are implemented in finite element (FE) models of rectangular U and V notched tensile specimens. The material description outside the cohesive zone is representative of a fine grained 25% Cr duplex stainless steel, UNS32760-S. A three step procedure consisting of conventional elastic plastic stress analysis, stress driven diffusion analysis and finally cohesive zone fracture initiation analysis makes the basis for the presented work. The applied boundary conditions are representative of mechanical stresses and environmental loads on an oil and gas pipeline in subsea conditions. A linear traction separation law gives reasonably good fit with experimental results for gross stress levels of 0.85–0.9 times the material yield stress. Hydrogen concentration of 40 ppm at the surface and 1 ppm in bulk always gives crack initiation at the surface despite the peak normal stress localized in front of the notch tip.

Texto completoResumen
This paper presents the preliminary results from a friction drag reduction experiment conducted at high Reynolds numbers. The experiments were conducted in two phases at the U. S. Navy’s William B. Morgan Large Cavitation Channel (LCC) in Memphis, TN on a flat, hydraulically smooth plate (12.9 meters long by 3.0 meters wide by 0.18 meters thick) at flow speeds ranging from 0.5 to 20 m/s. The employed drag reduction technique involved the injection of microbubbles into the boundary from a line source over a range of injection flow rates from 100 to 800 scfm. These results include mean velocity data and spatially averaged shear stress data acquired in the single-phase flow, as well as spatially averaged shear stress data, bubble images, and void fraction measurements made in the bubble-injected flow.

<p>The U-shaped rib-to-deck welded joint in orthotropic steel deck is a part with multiple fatigue cracks. The penetration rate which is the ratio of penetration depth to U-shaped rib thickness has an important influence on fatigue performance of partial joint penetration (PJP) welds. In this study, the influence of penetration rate on the fatigue performance of U-shaped rib-to-deck welded joints was studied. Firstly, the finite element model of U-shaped rib-to-deck welded joints with penetration rate of 65%, 75%, 85% and complete joint penetration (CJP) welds were established. The mechanical characteristics of different welding forms under typical loading conditions were analyzed. It was found that with the increase of penetration rate of PJP welds, the stress concentration at the weld root weakened. Then fatigue tests on specimens with different weld penetration rate were carried out. The fatigue cracks of CJP welds all started at the inner welding toe of the U-shaped rib. However, the fatigue cracks of PJP welds mainly started at the welding root of the unfused weld. Fatigue S-N curves for PJP and CJP were regressed, respectively, it could be found that the fatigue performance of CJP welds was superior to that of PJP welds.</p>
