Solar Light Photocatalytic CO2 Reduction: General Considerations and Selected Bench-Mark Photocatalysts (2014)

The reduction of carbon dioxide to useful chemicals has received a great deal of attention as an alternative to the depletion of fossil resources without altering the atmospheric CO2 balance. As the chemical reduction of CO2 is energetically uphill due to its remarkable thermodynamic stability, this process requires a significant transfer of energy. Achievements in the fields of photocatalysis during the last decade sparked increased interest in the possibility of using sunlight to reduce CO2. In this review we discuss some general features associated with the photocatalytic reduction of CO2 for the production of solar fuels, with considerations to be taken into account of the photocatalyst design, of the limitations arising from the lack of visible light response of titania, of the use of co-catalysts to overcome this shortcoming, together with several strategies that have been applied to enhance the photocatalytic efficiency of CO2 reduction. The aim is not to provide an exhaustive review of the area, but to present general aspects to be considered, and then to outline which are currently the most efficient photocatalytic systems.

Settlement of a marine tube worm as a function of current velocity: Interacting effects of hydrodynamics and behavior<sup>1</sup> (1993)

Settlement experiments were conducted with larvae of Phragmatopoma lapidosa californica (a reef‐building sabellariid polychaete) in turbulent flume flows (near‐surface velocities of 5, 10, 15, 20, 25, 30, and 35 cm s −1 ) over a hydrodynamically smooth bed. Boundary shear velocities spanned the critical shear velocity for initiation of particle motion and for suspended‐load transport of passive larval mimics. Larvae were allowed one pass over a sediment array with two treatments: tube sand, a natural inducer of metamorphosis, and noninductive sand. Delivery of larvae to the array was the result of interactions between the flow regime and larval behavior. At intermediate flows (15, 20, and 25 cm s −1 ), where numbers of metamorphosed juveniles and total animals (larvae + juveniles) in the array were maximal, larvae tumbled along the flume bottom, as did the passive larval mimics. At slower flows, larvae actively left the bottom and swam into the water, passing over the array. At the fastest flows, hydrodynamics alone may have reduced settlement because larvae, like the mimics, were eroded from the bed and carried as suspended load over the array or because enhanced turbulent mixing distributed larvae more evenly in the water, thus reducing their concentration close to the bed. Once delivered to the substratum, behavioral responses to chemical cues were ultimately responsible for metamorphosis; in all flows, >96% of metamorphosed juveniles were in the tube sand, whereas most unmetamorphosed larvae were in noninductive sand.
Chemotherapy induced peripheral neuropathic pain (2014)

Chemotherapy-induced peripheral neuropathy (CIPN) is one of the most serious complications associated with anticancer drugs. CIPN leads to a lower quality of life and dysfunction of the sensory, motor, and autonomic systems, and often causes patients to discontinue chemotherapy. It is usually misdiagnosed and undertreated due to a lack of consensus and unclear pathophysiology, for which many mechanisms have been suggested, including mitochondrial dysfunction, various pain mediators, abnormal spontaneous discharge in A and C fibers, and others. To date, no agents have been shown to effectively prevent CIPN, leading to debate as to the standard protocol. Duloxetine has demonstrated a moderate therapeutic effect against CIPN. Although tricyclic antidepressants (such as nortriptyline or desipramine), gabapentin, and a topical gel containing baclofen (10 mg), amitriptyline HCL (40 mg), and ketamine (20 mg) showed inconclusive results in CIPN trials, these agents are currently considered the best options for CIPN treatment. Therefore, further studies on the pathophysiology and treatment of CIPN are needed. (
Cytomegalovirus infection after autologous bone marrow transplantation: occurrence of cytomegalovirus disease and effect on engraftment (1990)

Epidemiologic and clinical characteristics of cytomegalovirus (CMV) infection and disease were analyzed retrospectively in 159 autologous marrow transplant recipients. The probability of CMV infection by day 100 after transplant was 22.5% in patients seronegative to CMV before transplant versus 61.1% in seropositive patients (P less than .0001 by logrank test). Multivariate analysis identified positive pretransplant CMV serology as the only definable risk factor for CMV infection (relative risk 1.4, P less than .0001). CMV pneumonia developed in 11 patients at a median time of 100 days after transplant and was fatal in nine cases. CMV pneumonia was associated with significantly decreased probability of survival by day 100 after transplant (relative risk of death of 16.7, P less than .0001). In contrast to earlier reports, CMV infection had no significant effect on the rapidity of platelet or neutrophil recovery after transplant as assessed by time-dependent multivariate analysis. Because the incidence of severe CMV disease is not negligible after autologous marrow transplantation, preventive measures against CMV infection are warranted, as in allogeneic marrow transplantation.
Talent Circle Detection in Job Transition Networks (2016)

With the high mobility of talent, it becomes critical for the recruitment team to find the right talent from the right source in an efficient manner. The prevalence of Online Professional Networks (OPNs), such as LinkedIn, enables the new paradigm for talent recruitment and job search. However, the dynamic and complex nature of such talent information imposes significant challenges to identify prospective talent sources from large-scale professional networks. Therefore, in this paper, we propose to create a job transition network where vertices stand for organizations and a directed edge represents the talent flow between two organizations for a time period. By analyzing this job transition network, it is able to extract talent circles in a way such that every circle includes the organizations with similar talent exchange patterns. Then, the characteristics of these talent circles can be used for talent recruitment and job search. To this end, we develop a talent circle detection model and design the corresponding learning method by maximizing the Normalized Discounted Cumulative Gain (NDCG) of inferred probability for the edge existence based on edge weights. Then, the identified circles will be labeled by the representative organizations as well as keywords in job descriptions. Moreover, based on these identified circles, we develop a talent exchange prediction method for talent recommendation. Finally, we have performed extensive experiments on real-world data. The results show that, our method can achieve much higher modularity when comparing to the benchmark approaches, as well as high precision and recall for talent exchange prediction.
The Role of Perfluorocarbon in Organ Preservation (2010)

Perfluorocarbons (PFCs) are inert solutions that have a high capacity for dissolving oxygen. There has been a continuing level of research into the delivery of oxygen during solid organ preservation with the use of PFCs. The one- and two-layer methods have been used as static storage techniques, proving particularly successful for pancreas preservation. They can also be formulated as an emulsion for continual perfusion or as a simple flush solution. The success of PFCs in organ preservation seems to be somewhat organ and species dependant, and further experimental evidence is needed to establish their application.
Expression and regulation of osteopontin in type 1 diabetes (2009)

Osteopontin (OPN) is a secreted acidic phosphoprotein that is involved in many inflammatory and immune-modulating disorders. We previously demonstrated that OPN is a novel islet protein and a pro survival factor that may serve as an intrinsic feedback regulator of nitric oxide signaling in β-cells. Here, we investigated the endogenous expression of pancreatic OPN in non obese diabetic (NOD) mice and explored its regulation in the islets and b-cells. High levels of pancreatic OPN mRNA and protein were seen in the prediabetic NOD mice pancreata. The temporal pattern of OPN expression inversely correlated with progression of insulitis and β-cell destruction. Immunostaining of pancreatic serial sections showed co localization of OPN with most of the islet hormones. Next we investigated the regulation of OPN in the islets and β-cells. Naturally occurring early upregulation of OPN transcription was seen after exposure of native normoglycemic NOD islets and β-cells to a high-dose combination of IL-1β, TNF-α and IFN-γ. To distinguish between the effect of cytokines and high glucose on OPN transcription, RINm5F cells were transfected with luciferase-labeled rat OPN promoter and treated with cytokines or glucose. Cytokines induced upregulation of OPN promoter activity within one hour, while glucose induced a dose-dependent upregulation of OPN promoter activity after 24 hrs. Long-term exposures to cytokines or glucose reduced OPN expression and promoter activity. Our data provide the first observations into the presence of a positive intrinsic mechanism that regulates pancreatic OPN expression. Based upon previous studies that support a protective role of OPN in the islets, our data suggest that exhaustion of this local OPN system is implicated in the associated loss of endogenous islet protection and progression of the destructive insulitis and diabetes severity in the NOD mouse model.
A comparison of shipborne and airborne electromagnetic methods for Antarctic sea ice thickness measurements (2003)

The three-dimensional modelling program MARCO_AIR has been used to calculate the response of idealised pressure ridges to practical airborne and shipborne electromagnetic systems. The model results clearly show the superior resolution of the horizontal coplanar ship-borne system compared to airborne measurements. However, sea ice keel thicknesses estimated via inversion of ship-borne single-frequency electromagnetic data are strongly dependent on relatively small variations in survey altitude.Inversion of helicopter electromagnetic data over 3D pressure ridge models shows that the maximum keel thickness is consistently underestimated, although airborne EM methods yield reliable thickness estimates over level ice. The vertical coaxial coil survey geometry offers excellent lateral resolution of multiple targets, but the anomalies of typical Antarctic sea ice pressure ridges would be too small to detect in practical surveys using a close-coupled (2 - 3 m) geometry. For a system with a coil separation of 8 m, the vertical coaxial responses are larger, and lateral resolution of the measurements at a flight height of 20 m is superior to a close-coupled system flown at an altitude of 10 m.
Characterization of a renal tubular epithelial cell line which secretes the autologous target antigen of autoimmune experimental interstitial nephritis. (1988)

Proximal tubular epithelial cells from mice which develop autoimmune interstitial nephritis were found to express the nephritogenic target antigen, 3M-1. Anti-3M-1 mAbs (alpha 3M-1-Ab) were used to positively select for 3M-1-secreting tubular epithelium and, after stabilization in culture, this new cell line (MCT) was examined for the production of several moieties important to either immune interactions or to the development of extracellular matrix. Alkaline phosphatase-staining MCT cells also express epithelial growth factor receptors with a Kd of 0.87 nM and an epithelial growth factor receptor constant (Ro) of 2.1 X 10(4) receptors/cell. MCT culture supernatants contain greater amounts of laminin, and types IV and V procollagens compared to types I and III procollagens, and growing MCT cells on type I collagen matrix causes them to preferentially secrete even more type IV and V procollagen. The 30,000-Mr 3M-1 antigen could be immunoprecipitated from biosynthetically labeled MCT cell supernatants with alpha 3M-1-Ab. An identical-sized moiety was isolated by immunoaffinity chromatography from collagenase-solubilized mouse kidney tubular basement membranes. The 3M-1 antigen can be found on the MCT cell surface by radioimmunoassay, or deposited in a linear array in the extracellular matrix surrounding the MCT cells in culture by immunofluorescence. Mature messenger RNA species for both class I and class II major histocompatibility complex (MHC) molecules were detected by Northern hybridization, and their corresponding cell surface gene products were detected by cytofluorography of MCT cells stained with haplotype-specific antibodies. Both the cell surface 3M-1 and the small amounts of detected class II MHC molecules appear to be biologically functional, as MCT cells can support the proliferation of 3M-1-specific, class II MHC-restricted helper T cells in culture. These findings suggest that MCT cells provide all the necessary biological parameters for interfacing both as the target of a nephritogenic immune response, and as a potential source for new extracellular matrix which develops as a fibrogenic response to interstitial nephritis.
The influence of rounded edges on indentation by a flat punch (1998)

The contact problem and stress state for indentation by a flat punch with rounded edges is studied. For the contact problem itself analytical solutions are obtained for both surface pressure and interior stress fields. Cases of normal indentation and frictional contact, the latter in both sliding or partial slip conditions, are all treated. The transition from the Hertzian configuration to the contact between a nominally flat pad and contacting flat surface is discussed, and it is found that the strength of the contact decays surprisingly slowly. Regarding the von Mises yield parameter, there is a range of configurations for which the strength is actually higher than the Hertzian one, and the strength decays only when the corner radii are very small. The present solution is therefore a realistic alternative to the classical rigid-flat punch idealization, and has particular application to fretting fatigue tests.
Effects of plasticizers and surfactants on the film forming properties of hydroxypropyl methylcellulose for the coating of diclofenac sodium tablets (2009)

Hydroxy propyl methyl cellulose (HPMC) 5cPs, an aqueous soluble polymer was employed for coating diclofenac sodium (DFS) tablets 25 mg for protecting the integrity of the drug yet rendering the drug to release at a faster rate on contact with the gastric environment. Proper optimization for the aqueous based film coating formulation was undertaken primarily employing plasticizers like polyethylene glycol (PEG) 400 and propylene glycol (PG). The defect free selected formulations were further subjected for studying the effects of surfactants like sodium lauryl sulphate (SLS) and Tween-80 along with the plasticizers. The quality of the aqueous film coats or the plasticizer efficiency in case of PEG-400 is in the order 1.5 > 0.5 > 1.0% and for PG 1 > 4 > 3% which can be stated on the basis of less incidence of major coat defects like chipping, cracking, orange peel, roughness, blistering, blooming, picking. The quality of aqueous film coat or the surfactant efficiency in case of SLS + PEG-400 is in the order 0.3 < 0.5 < 0.1% and SLS + PG is in the order 0.5 < 0.1 < 0.3%. In case of Tween-80 + PEG-400 the order is 0.3 < 0.5 < 0.1% and Tween-80 + PG is in the order 0.3 < 0.1 < 0.5%. Elegant film formation can be stated from fewer incidences of coat defects. The obtained coated tablets eventually satisfied all the normal physical parameters like thickness, weights, and weight gain, drug content, crushing strength, percent friability, disintegration time, dissolution profile and possible drug-polymer interactions. ANOVA was undertaken followed by Dunnet multiple comparison for the dissolution profile considering uncoated as the standard. The difference was considered significant at p ⩽ 0.01.

Hepatitis C lookback (2000)

Hepatitis C was responsible for the majority of cases of posttransfusion hepatitis before the introduction of a specific screening test for blood donors. Infected recipients may remain asymptomatic for many years, but cirrhosis and hepatocellular carcinoma may develop decades after infection. Lookback, or the identification of recipients of potentially contaminated blood, is now being conducted in many countries, including Holland, Denmark, the United Kingdom, Canada, New Zealand, and the United States. In targeted lookback, recipients of blood from donors subsequently found to be positive for hepatitis C are notified and advised to undergo testing. In general lookback, all patients who received blood before being tested for hepatitis C are advised to undergo testing. Difficulties with both forms of lookback illustrate the importance of vein-to-vein tracking of blood products, including the potential utility of a centralized registry of blood product recipients.
Ultrasonic Level, Temperature, and Density Sensor (1982)

A sensor has been developed to measure simultaneously the level, temperature, and density of the fluid in which it is immersed. The sensor is a thin, rectangular stainless steel ribbon which acts as a waveguide and is housed in a perforated tube. The waveguide is coupled to a section of magnetostrictive material which is surrounded by a pair of magnetic-coil transducers. These transducers are excited in an alternating sequence to interrogate the sensor with both torsional ultrasonic waves, utilizing the Wiedemann effect, and extensional ultrasonic waves, using the Joule effect. The measured torsional wave transit time is a function of the density, level, and temperature of the fluid surrounding the waveguide. The measured extensional wave transit time is a function of the temperature of the waveguide only. The sensor is divided into zones by the introduction of reflecting surfaces at measured intervals along its length. Consequently, the transit times from each reflecting surface can be analyzed to yield a temperature profile and a density profile along the length of the sensor. Improvements in acoustic wave dampener and pressure seal designs enhance the compatibility of the probe with high-temperature, high-radiation, water-steam environments and increase the likelihood of survival in such environments. Utilization of a microcomputer to automate data sampling and processing has resulted in improved resolution of the sensor.
Optimal Rescheduling of Generators for Congestion Management Based on Particle Swarm Optimization (2008)

Power system congestion is a major problem that the system operator (SO) would face in the post-deregulated era. Therefore, investigation of techniques for congestion-free wheeling of power is of paramount interest. One of the most practiced and an obvious technique of congestion management is rescheduling the power outputs of generators in the system. However, all generators in the system need not take part in congestion management. Development of sound formulation and appropriate solution technique for this problem is aimed in this paper. Contributions made in the present paper are twofold. Firstly a technique for optimum selection of participating generators has been introduced using generator sensitivities to the power flow on congested lines. Secondly this paper proposes an algorithm based on particle swarm optimization (PSO) which minimizes the deviations of rescheduled values of generator power outputs from scheduled levels. The PSO algorithm, reported in this paper, handles the binding constraints by a technique different from the traditional penalty function method. The effectiveness of the proposed methodology has been analyzed on IEEE 30-bus and 118-bus systems and the 39 -bus New England system.
Amino acid sequence of a carboxypeptidase inhibitor from tomato fruit (1981)

The amino acid sequence of a 37 residue carboxypeptidase inhibitor from tomato fruit has been determined. The amino terminus was shown to be 2-oxopyrrolidine-5-carboxylic acid by digestion of reduced and S-carboxymethylated inhibitor with pyroglutamate aminopeptidase. The remainder of the sequence was assigned by analysis of peptides which had been generated by specific cleavage at the Asp4-Pro5 bond under acid conditions and by treatment with trypsin. The amino acid sequence of this inhibitor is identical with that of an analogous inhibitor from potatoes in 26 positions, and two of the replacements are highly conservative. The identification of the nonconservative replacements has been used to better define regions of the inhibitor which are not believed to contribute significantly to the free energy of association of the enzyme-inhibitor complex.
Nutritive values of corn, soybean meal, canola meal, and peas for broiler chickens as affected by a multicarbohydrase preparation of cell wall degrading enzymes (2005)

The effect of a new multicarbohydrase supplement of cell wall degrading activities on the nutritive value of corn, soybean meal (SBM), canola meal (CM), and peas for broiler chickens was investigated. Four isoenergetic and isonitrogenous corn (69% corn), SBM (30% SBM, 59% corn), CM (30% CM, 54% corn), and pea (30% peas, 52% corn) diets, without or with enzyme supplementation, were formulated to meet NRC specifications for broiler chickens (except for AME and CP, which were at 95 and 92% of NRC requirements, respectively). The enzyme supplement supplied 1,000 U of xylanase, 400 U of glucanase, 1,000 U of pectinase, 120 U of cellulase, 280 U of mannanase, and 180 U of galactanase per kilogram of diet. Each diet was fed in a mash form to 9 replicate pens of 5 broilers from 5 to 18 d. When compared with the control treatment, enzyme addition to the corn diet improved (P < 0.05) feed-to-gain ratio, whereas the performance of birds fed the other 3 diets was not affected. An increase (P < 0.05) in total tract nonstarch polysaccharides (NSP) digestibility, ileal starch digestibility, and AMEn was observed in birds fed the enzyme-supplemented corn diet. An improvement (P < 0.05) in total tract NSP digestibility, ileal protein digestibility, and AMEn content with enzyme supplementation was observed for the SBM diet. However, nutrient digestibilities and AMEn of CM and pea diets were not affected (P > 0.05) by enzyme addition even though the NSP digestibilities increased significantly (P < 0.05). A significant increase (P < 0.05) in water-soluble NSP and a decrease (P < 0.05) in water-insoluble NSP concentration of ileal digesta was noted for birds fed all 4 enzyme-supplemented diets. It would appear from this study that the nutrient utilization of corn-SBM diet by broilers could be enhanced by using an appropriate multicarbohydrase enzyme supplement. The nutrient encapsulating effect of cell wall polysaccharides in SBM, CM, and peas may not be the only factor responsible for incomplete nutrient utilization. The improvement in feed efficiency and starch availability in birds fed corn diet likely resulted from the cell wall degrading activity of the enzyme supplement.
