Metallurgical investigation of electron beam welded duplex stainless steel X2CrNiMoN22-5-3 with plasma nitrided weld edge surfaces (2018)

Abstract Duplex stainless steel is common in thick-walled components such as longitudinal welded pipes in the oil and gas industries and as parts of various machines in the chemical and food industries. Electron beam welding is a very suitable method for welding such components. Due to the high power density of the electron beam combined with the decreased evaporation temperature in a vacuum atmosphere, steel with a sheet thickness of up to 150 mm can be welded in one pass. In the case of the electron beam welding of duplex stainless steels, vacuum atmosphere in the working chamber causes a nitrogen effusion from the weld pool. The microstructure of the resulting weld is characterized by an unacceptable high ferrite content, which is the main reason for both low impact toughness and low pitting corrosion resistance. This work focuses on the influence of nitrided weld edge surfaces on metallurgical properties of the resulting welded joint. The aim here is to investigate the effect of increased nitrogen content at the weld edges on nitrogen loss during EB-welding. The welds produced within the experimental work were characterized by means of microstructural analysis and the use of optical and energy dispersive X-ray spectroscopy. It was shown that nitrided weld edge surfaces can compensate nitrogen loss from the weld pool and decrease the ferrite content in the resulting weld.
Mn-Superoxide Dismutase Overexpression Enhances G 2 Accumulation and Radioresistance in Human Oral Squamous Carcinoma Cells (2006)

This study investigates the hypothesis that Mn-superoxide dismutase (MnSOD) influences cancer cell radiosensitivity by regulating the G(2)-checkpoint pathway. Human oral squamous carcinoma cells (SCC25) stably overexpressing MnSOD were irradiated (6 Gy) and assayed for cell survival, cell-cycle phase distributions, and bromodeoxyuridine (BrdU) pulse-chase flow-cytometric measurements of cell-cycle phase transits. Electron paramagnetic resonance (EPR) spectroscopy was used to measure steady-state levels of oxygen-centered free radicals. Glutathione and glutathione disulfide levels were used as indicators of changes in the intracellular redox state. MnSOD overexpression increased radioresistance threefold to fourfold; this increase was associated with twofold to threefold increases in radiation-induced G(2) accumulation. BrdU pulse-chase and flow-cytometric measurements of the percentage of G(1) and relative movement showed no significant changes in G(1) and S transits; however, the percentage of G(2) cells and BrdU-positive cells showed delayed G(2)+M transits in MnSOD-overexpressing irradiated cells. The steady-state levels of oxygen-centered free radicals were not significantly different in vector compared with MnSOD-overexpressing cells, suggesting that the free radical generation is essentially similar. MnSOD overexpression did prevent radiation-induced decreases in total glutathione content, which correlated with radioresistance and enhanced G(2) accumulation. These results support the hypothesis that a "metabolic redox-response" to IR exposure regulates radiosensitivity by altering radiation-induced G(2) accumulation.
Einsatz von Albumin (2021)

The Saline versus Albumin Fluid Evaluation (SAFE) study has demonstrated that the use of albumin as an infusion solution in volume therapy can be regarded as safe. An exception is hypo-oncotic albumin in traumatic brain injury. While clear indications of albumin exist for some patients with liver cirrhosis, large studies that demonstrate a clinically relevant advantage beyond hemodynamic effects and would therefore justify wider use in many other areas are still lacking. In large-volume paracentesis, spontaneous bacterial peritonitis, but also in hepatorenal syndrome, use of albumin is recommended and established due to clinical benefit in randomized controlled trials. In septic shock, use of albumin may be considered, with two large studies addressing this issue in Germany and Italy being still in the recruitment phase. For volume therapy, albumin can be used primarily when other measures for hemodynamic stabilization have been exhausted. This applies to volume resuscitation in hypovolemia as well as in conservative fluid management in the so-called "de-resuscitation" phase. The extent to which the correction of severe hypoalbuminemia with exogenous albumin can improve the impaired outcome of these patients is also part of ongoing studies. On the way to a more individualized medicine, hypoalbuminemia may serve as a parameter in future decision making for or against the use of albumin in volume therapy.

and, furthermore, in contrast to the metal ion hetero- geneity (Zn2+ plus Cd) found in cadmium-induced vertebrate metallothioneins, the crab metallothionein contains only Cd. The '13Cd NMR spectrum of Cd2+- induced crab MT-1 shows five resolved multiplets in the chemical shift range of
Preview Lateral Control With Machine Vision For Intelligent Vehicle (2005)

This paper describes a new preview lateral control algorithm for an autonomous vehicle with machine vision and experiments with an AGV conducted to demonstrate the feasibility of the algorithm. The algorithm uses the whole information in the two-dimensional field of view, which enables robust and smooth lateral control. Compensation of the delay due to the time for image processing is also considered.
RISK MANAGEMENT IN PRODUCT DEVELOPMENT - CURRENT METHODS (2006)

Products and processes in product development are becoming increasingly complex. As a result, errors associated with product development increase, thus product and process failures become more and more frequent. This leads ultimately to an increase in the number of crises related to product
Mapping sources of noise in an intensive care unit (2019)

Excessive noise in hospitals adversely affects patients' sleep and recovery, causes stress and fatigue in staff and hampers communication. The World Health Organization suggests sound levels should be limited to 35 decibels. This is probably unachievable in intensive care units, but some reduction from current levels should be possible. A preliminary step would be to identify principal sources of noise. As part of a larger project investigating techniques to reduce environmental noise, we installed a microphone array system in one with four beds in an adult general intensive care unit. This continuously measured locations and sound pressure levels of noise sources. This report summarises results recorded over one year. Data were collected between 7 April 2017 and 16 April 2018 inclusive. Data for a whole day were available for 248 days. The sound location system revealed that the majority of loud sounds originated from extremely limited areas, very close to patients' ears. This proximity maximises the adverse effects of high environmental noise levels for patients. Some of this was likely to be appropriate communication between the patient, their caring staff and visitors. However, a significant proportion of loud sounds may originate from equipment alarms which are sited at the bedside. A redesign of the intensive care unit environment to move alarm sounds away from the bed-side might significantly reduce the environmental noise burden to patients.
The Effect of Oat Beta‐Glucan on Clinical Lipid Markers for Cardiovascular Disease Risk Reduction: A Systematic Review & Meta‐Analysis of Randomized Controlled Trials (2016)

Background Oats are a rich source of β‐glucan, a viscous soluble fibre recognized for its cholesterol lowering properties, and are associated with reduced risk of cardiovascular disease. Objective To conduct a systematic review and meta‐analysis of RCTs investigating the cholesterol lowering potential of oat β‐glucan on LDL‐C, non‐HDL‐C, and apoB, for the risk reduction of cardiovascular disease. Design MEDLINE, Embase, CINAHL, and the Cochrane Central Register of Controlled Trials were searched. We included Only RCTs of ≥ 3 weeks duration assessing the effect of diets enriched with oat β‐glucan compared with controlled diets on LDL‐C, non‐HDL‐C, or apoB. Two independent reviewers extracted relevant data and assessed study quality and risk of bias. Data were pooled using the generic inverse variance method with random effects models and expressed as mean differences (MD) with 95% confidence intervals (CIs). Heterogeneity was assessed by the Cochran Q statistic and quantified by the I 2 statistic. Results 58 trials (N = 3952) were included in the final analysis. A median dose of 3.5 g/day of oat β‐glucan significantly lowered LDL‐C (MD = −0.19 mmol/L [95% CI: −0.23, −0.14] P &lt; 0.00001) non‐HDL‐C (MD = −0.20 mmol/L [95% CI: −0.26, −0.15] P &lt; 0.00001) and apoB (MD = −0.03 g/L [95% CI: −0.05, −0.02] P &lt; 0.0001) compared to control interventions. There was evidence of considerable unexplained heterogeneity in the analysis of LDL‐C (I 2 = 79%) and non‐HDL‐C (I 2 = 99%). Conclusion Pooled analyses show that oat β‐glucan have a lowering effect on LDL‐C, non‐HDL‐C, and apoB. Inclusion of oat containing foods may be a strategy for achieving targets in cardiovascular disease reduction.
Practical Considerations in Estimating Test Duration for Perforation Inflow Tests (2009)

Abstract Perforation inflow tests are short, cost-effective and environmentally- friendly solutions to estimate the initial reservoir pressure, permeability and skin, immediately after perforating the well. The reservoir-dominated (radial) flow regime must be reached before terminating the test in order to obtain reasonable estimates of these parameters. These reservoir parameters and chamber (or wellbore) volume directly influence the rate of build-up of pressure and the test duration. In the field, it is not easy to ascertain whether or not sufficient data has been obtained so that the test can be terminated, especially when the data is not analyzed in real time. If the rate of build-up is closely monitored, it is possible to predict whether (i) the minimum required data will be obtained within the stipulated test time, (ii) the test has to be run longer, or (iii) a downhole shut-in is required. In this paper, analytical simulation is used to run a sensitivity study on reservoir and well parameters and see how these affect the onset of the reservoir-dominated flow regime. The impulse derivative is used to identify the presence of reservoir-dominated flow. The rate of pressure build-up at I hour is used to determine if sufficient data will be collected within the test duration. The outcome is a practical field guide to help the operator decide whether the test should be continued, modified or stopped. Introduction Perforation inflow tests are short and therefore increasingly popular in the industry. They can deliver valuable reservoir information, such as the initial reservoir pressure, the reservoir permeability and the skin effect. The data obtained from perforation inflow tests can be divided into two parts:the early-time data is wellbore storage dominated, andthe late-time data is reservoir- dominated. Perforation inflow tests are not likely to exceed approximately 24 hours, and should be designed so that reservoir-dominated flow occurs during that period. For cases where wellbore storage does not excessively affect the early time data and when reservoir permeability is high enough, the duration of the perforation inflow test is likely sufficient to reach radial flow. However, for large wellbore storage and low reservoir permeability, the time to reach reservoir- dominated flow will be prohibitively long. In such cases, one option is to reduce wellbore storage by running a bridge plug, thus reducing the effects that initially masked the true reservoir performance.
Arsenic and nitrogen removal during shale oil upgrading (1978)

A reactor model for removal of As and N from shale oil is presented. For shale oil hydrotreating, the reactor model must take into account the effect of arsenic since arsenic is a strong catalyst poison. Even with a guard bed, arsenic is deposited continually throughout the cycle and to compensate for its poisoning effect temperature must be raised to maintain denitrification activity. Because of the highly exothermic reaction, means of heat removal are required to control reactor temperature. As the catalyst activity declines, both due to arsenic and time on stream, conversion in each catalyst bed changes. The lower conversion gives less heat release and, therefore, bed temperature must be increased to maintain catalyst activity. This in turn greatly changes the required hydrogen quench after each catalyst bed as the cycle progresses. Using the developed model the overall shale upgrading process can be optimized. Since arsenic removal and denitrification are highly interdependent, the reactor design needs to be studied in order to minimize overall processing costs. One use of the model is to determine the optimum conditions for arsenic removal since any arsenic leakage directly affects the required severity and cycle life for denitrification. As the arsenic removal ismore » increased via increased guard reactor size, capital costs increase but catalyst usage decreases. The optimum design for denitrification can be found using the model. Conditions are chosen so arsenic removal and coke deposition are balanced to minimize costs.« less
Lrp–DNA complex stability determines the level of ON cells in type P fimbriae phase variation (2011)

Summary F165 1 and the pyelonephritis‐associated pili (Pap) are two members of the type P family of adhesive factors that play a key role in the establishment of disease caused by extraintestinal Escherichia coli (ExPEC) strains. They are both under the control of an epigenetic and reversible switch that defines the number of fimbriated (ON) and afimbriated (OFF) cells within a clonal population. Our present study demonstrates that the high level of ON cells found during F165 1 phase variation is due to altered stability of the DNA complex formed by the leucine‐responsive regulatory protein (Lrp) at its repressor binding sites 1–3; after each cell cycle, complex formation is also modulated by the local regulator FooI (homologue to PapI) which promotes the transit of Lrp towards its activator binding sites 4–6. Furthermore, we identified two nucleotides (T490, G508) surrounding the Lrp binding site 1 that are critical to maintaining a high OFF to ON switch rate during F165 1 phase variation, as well as switching Pap fimbriae towards the OFF state.
Relative increase of serum reverse T3 in patients with hypothyroidism. (1978)

In 17 hypothyroid patients serum T3: rT3 ratio was 7.5 /+- 1.1 which was significantly lower than in control subjects (12.2 /+- 0.6; p less than 0.001). The data suggest that in hypothyroidism the organism might shift conversion of T4 from biologically active T3 to biologically inactive rT3 which may not be a defense mechanism of the body, as it was found in chronic systemic illness.
Molecular cloning and characterization of the gene encoding mouse melanoma antigen by cDNA library transfection (1992)

We have isolated a cDNA (H52) of 2.8-kb-long encoding an 80-kDa mouse melanoma Ag that is defined by a syngeneic anti-B16 melanoma mAb with an ability to block anti-melanoma cytotoxic T cell responses. H52 transfectants were brightly stained with the antibody, and the 80-kDa molecule was immunoprecipitated from the transfectants. Northern blot analysis showed that this transcript was detected in mouse melanoma cells of C57BL/6 and DBA/2 origin, C1300 A/J neuroblastoma, L cell (C3H) and EL-4 T lymphoma (C57BL/6), faintly in BW5147 (AKR) T lymphoma, but not in other tumors, such as S913 fibrosarcoma (C57BL/10), NIH3T3, 70 Z/3 pre-B lymphoma, and P3U1 plasmacytoma (BALB/c). Since the transcripts were not found in normal C57BL/6 tissues of fetus, newborn, and adult origin, the H52 expression is associated with transforming phenotypes. However, no tissue- or cell type-specific expression was observed. Nucleotide sequence analysis has clearly demonstrated that H52 cDNA encodes the full length of the env gene and long terminal repeat region of endogenous ecotropic murine leukemia provirus of AKV-type, which is defective in C57BL/6. The H52 envelope protein has several amino acid changes compared to those of AKV, one of which is in the env 14 peptide region preferentially associated with MHC molecule, suggesting the possible reason for the difference of antibody reactivity even in H52-positive tumors. We also demonstrate that CTL against H52 transfectant kills B16 melanoma. Thus, the above results are direct evidence that even the endogenous self molecule, when constitutively expressed, does act as a tumor Ag.
Predictive and Prognostic Values of Tau and ERCC1 in Advanced Breast Cancer Patients Treated with Paclitaxel and Cisplatin (2010)

Tau expression but not excision repair cross-complementing 1 in advanced breast cancer predicts poor response to combination chemotherapy of paclitaxel and cisplatin. However, tau expression is significantly associated with longer overall survival.
Hearing support system using environment sensor network (2016)

In order to solve the problems of current hearing aid devices, we make use of environment sensor network, and propose a hearing support system, where individual target and anti-target sound sources in the environment can be selected, and spatial information of the target sound sources is reconstructed. The performance of the selective sound separation module was evaluated for different noise conditions. Results showed that signal-to-noise ratios of around 15dB could be achieved by the proposed system for a 65dB babble noise plus directional music noise condition. In the same noise condition, subjective intelligibility tests were conducted, and an improvement of 65 to 90% word intelligibility rates could be achieved by using the proposed hearing support system.
Proton as a Possible Neurotransmitter for Perivascular Axo-axonal Transmission in the Rat Mesenteric Resistance Artery (2009)

The rat mesenteric resistance arteries are densely innervated by adrenergic vasoconstrictor nerves, CGRPergic vasodilator nerves and nitric oxide-containing nerves. Those nerves have axo-axonal interactions to modulate vascular nerve function and to regulate vascular tone. The present study focused on a possible transmitter, which is involved in axo-axonal transmission of adrenergic nerves and CGRP nerves. When nicotine is applied in the rat perfused mesenteric artery, nicotine stimulates nicotinic α3β4 nicotinic acetylcholine receptors on adrenergic nerves. This stimulation leads to the release of proton from adrenergic nerves. Released proton activates transient receptor potential vanilloid-1 receptors on neighboring CGRP nerves and CGRP is released to cause vasodilation. The present findings would explain why CGRPergic nerves, which are capsaicin-sensitive sensory nerves, have efferent function in spite of being primary afferent nerves. Namely, efferent adrenergic nerves, which momentarily and constantly regulate the vascular tone, may send their information to the neighboring CGRPergic nerves. Proton may be used as the transmitter for axo-axonal transmission to counteract excess vasoconstriction as the efferent function of afferent sensory nerves. Recent study demonstrated that periarterial nerve stimulation of perfused mesenteric arteries resulted in a decrease in the pH level of the perfusate concomitant with CGRPergic nerve-mediated vasodilation, which was abolished by the adrenergic neuron blocker, guanethidine. These findings suggest that proton acts as a transmitter for axo-axonal transmission between adrenergic and CGRPergic nerves in mesenteric resistance arteries. In conclusion, the present study presents evidence that perivascular nerves have strong axo-axonal interaction to modulate nerve function and to regulate vascular tone.
Introducing Functionality to Fluorinated Electroactive Polymers (2019)

Fluorinated electroactive polymers (FEPs) are among the most interesting insulating materials for the production of organic electronic devices. Their ability to tune their response to an applied electric field makes them appropriate for vastly different applications in electronics. However, due to the chemical inertness of such polymers and the rather complex synthetic processes required for their production, introducing additional functionality to FEPs remains an open challenge. Here, we present a facile way to introduce additional functionality to FEPs and more specifically photopatternability by a simple etherification method, which allows us to introduce almost any functional group on FEPs. Photo-cross-linkable moieties were introduced on FEPs using this method, inducing photopatternability, while tuning their electroactive response with great property enhancement up to 60% in terms of relative permittivity in several cases.
Nonredundant Point Distribution for Coded Aperture Imaging with Application to Three-Dimensional On-Line X-Ray Information Retrieving (1975)

Conventional methods of displaying three-dimensional information in X-ray diagnostics like tomography or tomosynthesis are not capable of imaging fast moving objects because of the time-sequential recording process. To overcome this difficulty the method of coded aperture imaging using nonredundant point distributions is applied to X-ray imaging. The object coded by an array of X-ray sources is deconvoluted by means of an optical processing system using monochromatic, but spatially incoherent light. Experimental results obtained with simple objects show good resolution in detail as well as in depth. Moreover, an on-line system has been simulated using coded images on X-ray films with a TV-camera pick up in conjunction with an electrooptic relay tube.
