High Temperature Alloys for Gas Turbines

Sir William Griffiths presented a full and comprehensive review of the position with regard to high temperature alloys for gas turbines in his lecture (January 1948 JOURNAL), and one could only agree with all that had been said. Much credit was due to the metallurgists in evolving these high temperature materials, and their enthusiastic co-operation with the engineers had gone far in making the gas turbine a practical proposition.
Ferredoxin-NADP (cid:1) Reductase KINETICS OF ELECTRON TRANSFER, TRANSIENT INTERMEDIATES, AND CATALYTIC ACTIVITIES STUDIED BY FLASH-ABSORPTION SPECTROSCOPY WITH ISOLATED PHOTOSYSTEM I AND FERREDOXIN*

The electron transfer cascade from photosystem I to NADP (cid:1) was studied at physiological pH by flash-absorp-tion spectroscopy in a Synechocystis PCC6803 reconstituted system comprised of purified photosystem I, ferredoxin, and ferredoxin-NADP (cid:1) reductase. Experiments were conducted with a 34-kDa ferredoxin-NADP (cid:1) reductase homologous to the chloroplast enzyme and a 38-kDa N-terminal extended form. Small differences in kinetic and catalytic properties were found for these two forms, although the largest one has a 3-fold decreased affinity for ferredoxin. The dissociation rate of reduced ferredoxin from photosystem I (800 s (cid:2) 1 ) and the redox potential of the first reduction of ferredoxin-NADP (cid:1) reductase ( (cid:2) 380 mV) were determined. In the absence of NADP (cid:1) , differential absorption spectra support the existence of a high affinity complex between oxidized ferredoxin and semireduced ferredoxin-NADP (cid:1) reductase. An effective rate of 140–170 s (cid:2) 1 was also measured for the second reduction of ferredoxin-NADP (cid:1) reductase,
CORRELATION FOR THE PREDICTION OF EMISSION VALUES OF OXIDES OF NITROGEN AND CARBON MONOXIDE AT THE EXIT OF GAS TURBINE COMBUSTION CHAMBERS

This study sought to investigate the relationship between board characteristics and financial performance for the companies listed at the Nairobi securities Exchange (NSE). Financial performance was measured by Tobin’s Q, ROE, EPS, and DPS while the Board Characteristics considered were board independence (i.e. outsider dominated boards), board quality (i.e. board expertise and educational background) and the board diversity (i.e. the ethnic/racial, gender and age balance.) The data was analyzed using correlation and regression analysis to determine the level and type of association between the firms performance measures and the various corporate governance variables. The findings showed that only Board independence (BI) and Gender diversity had an effect on firms’ performances. Board independence had a negative correlation with ROE in the agricultural sector, while gender balance had a positive correlation with DPS and EPS for companies in the commercial and industrial sectors. Board quality had no significant impact on any of the performance variables.
A Simple Method of Discriminating between Occurrences of Freezing Rain and Ice Pellets in the Kanto Plain, Japan

Based on a freezing rain and ice pellet event observed on 3 January 2003 in the Kanto Plain, Japan, the atmospheric conditions necessary for the occurrence of such phenomena in this area were investigated, and a simple method of discriminating precipitation types, including freezing rain and ice pellets, was examined.Freezing rain and ice pellets fell from 1800 to 2400 JST on 3 January in the western portion of the Kanto Plain. During the precipitation, northwesterly cold-air advection near the surface dominated in this region, with southerly warm-air advection associated with the approach of a synoptic low present above the cold air layer. This atmospheric structure produced the conditions required for freezing rain and ice pellets to form, namely a melting layer with an air temperature above 0°C to melt snow particles into raindrops, and a refreezing layer with an air temperature below 0°C to supercool the raindrops into freezing rain or freeze them into ice pellets. ice the conditions required for the complete melting of snow particles and the complete freezing of raindrops during the event were examined theoretically. We found that the mean air temperatures, the mean relative humidities, and the depths of the melting and refreezing layers can be used to distinguish the environmental conditions required for freezing rain and ice pellets to form. In addition, determination of whether the wet-bulb temperature at the surface is above or below 0°C was used to discriminate rain and freezing rain. The distribution of precipitation types at 2100 JST on 3 January 2003 in the Kanto Plain was estimated using the method described above, and the results agreed closely with the distribution actually observed. The diagnostic method presented in this study enables the discrimination of precipitation types, including freezing rain and ice pellets.
University of Birmingham Reap what you sow

This paper studies how productivity-enhancing agricultural technology aﬀects urbanization by provoking structural change. We investigate these issues using a natural experiment in the United States. The results show that technologies which improve crop productivity lead to a less urbanized economy as economic activity relocates from manufacturing and services towards agriculture. The eﬀects are highly persistent and are driven by the technology increasing agricultural labor demand. Our ﬁndings high-light the potentially unintended, disruptive force of innovative technologies.
Comparison of Three Different Treatment Modalities in the Treatment of Chronic Plantar Fasciitis: Corticosteroid Injection, Extracorporeal Shock Wave Therapy and Radiofrequency Nerve Ablation

Aim: In this study, it was aimed to compare the clinical and functional outcomes of three popular conservative treatment options in the treatment of chronic plantar fasciitis (PF): corticosteroid injection (CSI), extracorporeal shock wave therapy (ESWT) and radiofrequency nerve ablation (RFNA). Material and Methods: Patients with chronic PF refractory to other conservative treatment methods were included in this retrospective study. From January 2017 to February 2019, all the patients with the diagnosis of chronic PF who were treated with conservative treatment modalities were evaluated. Forty eight patients who met our eligibility criteria and treated either with CSI, ESWT or RFNA methods were included in the study. Clinical and functional assessments of the patients were done by American Orthopaedic Foot and Ankle Society (AOFAS) scoring system and Visual Analogue Scale (VAS) just before the treatment, at 6 th and at 12 th weeks of the last session. Results: There was a statistically significant difference in terms of VAS scores between the groups both for before treatment and for 6 th week (both p<0.001), but there was not a statistically significant difference between the groups in terms of VAS scores at 12 th week (p=0.436). Also, there was not a statistically significant difference between the three groups in terms of AOFAS scores before treatment, 6 th and 12 th week assessments (p=0.076, p=0.081, p=0.478 respectively). Conclusion: Although the three treatment modalities showed significant improvements in the chronic PF treatment, no differences were found among effectiveness of them at the final follow-up period.

M athematics and M echanics of Complex Systems

This note deals with models of quantum systems where the emergence of a classical behavior can be concretely analyzed. We ﬁrst brieﬂy review some well known difﬁculties arising in the classical limit of quantum mechanics according to the Copenhagen interpretation. Then we discuss the seminal contribution by Mott (1929) on the tracks observed in a cloud chamber, where the problem can be approached in a particularly transparent way. Finally, we propose a model Hamiltonian, with interaction described by spin dependent point interactions, where Mott’s analysis can be rephrased and the result can be rigorously formulated.
Role of kisspep+n and RFRP on the circadian control of female reproduc+on

In female mammals, reproducIon shows ovarian and daily rhythms ensuring that the Iming of the greatest ferIlity coincides with maximal acIvity and arousal. The ovarian cycles, which lasts from a few days to a few weeks, depends on the rhythm in follicle maturaIon and ovarian hormone producIon, whereas the daily cycle depends on a network of circadian clocks of which the main one is located in the suprachiasmaIc nuclei (SCN). In the last ten years, major progress has been made in the understanding of the neuronal mechanisms governing mammalian reproducIon with the ﬁnding that two hypothalamic Arg-Phe-amide pepIdes, kisspepIn and RFRP, regulate GnRH neurons. In this review we discuss the pivotal role of Kp and RFRP neurons at the interface between the SCN clock signal and the GnRH neurons to Ime the gonadotropin-induced ovulaIon. We also report recent ﬁndings indicaIng that these neurons may be part of the mulI-oscillatory circadian system that Imes female ferIlity. Finally, we will discuss recent invesIgaIons indicaIng a role, and putaIve therapeuIc use, of these neuropepIdes in human reproducIon. day in diurnal species like humans). The mechanisms by which biological funcIons are synchronized to the light/dark signals involve the master biological clock located in the hypothalamic suprachiasmaIc nuclei (SCN) and the reIno-hypothalamic tract which forwards the non visual light to the SCN.
Insertion and Hairpin Formation of Membrane Proteins: A Monte Carlo Study

Some particular effects of a lipid membrane on the partitioning and the concomitant folding processes of model proteins have been investigated using Monte Carlo methods. It is observed that orientational order and lateral density fluctuations of the lipid matrix stabilize the orientation of helical proteins and induce a tendency of spontaneous formation of helical hairpins for helices longer than the width of the membrane. The lateral compression of the lipids on a hairpin leads to the extrusion of a loop at the trans side of the membrane. The stability of the hairpin can be increased by the design of appropriate groups of hydrophilic and hydrophobic residues at the extruded loop. It is shown that in the absence of lipids the orientation of proteins is not stable and the formation of hairpins is absent. Some analogies between the formation of helical hairpins in membranes and the formation of hairpins in polymer liquid crystals are discussed. The simulations indicate that the insertion process follows a well-defined pattern of kinetic steps.
The Journal of Asia TEFL The Effectiveness of Learners’ Preferred and Unpreferred Written Corrective Feedback: A Think-Aloud Study

In early written corrective feedback studies, there were a lot of attempts to test if the feedback types are effective. This study was based on the assumption prevailing in the new era of studies of written corrective feedback, that feedback is effective. Firstly, it aims to compare the think-aloud protocols of the preferred and unpreferred feedback types which were chosen by 20 English learners (10 in preferred, and 10 in unpreferred feedback). To this aim, learners were asked to write diaries for six weeks. In each session, concurrent think-aloud protocols were employed and learners' verbal reports were extracted, and their mental processes were coded through developing a table of mental operations. In the second part of the study, the relative effectiveness of the preferred and unpreferred feedback was measured. Using the Chi-square goodness-of-fit test, the findings of the first part showed a significant difference between the mental operations for each feedback type. The results for the second part suggested that there is a significant difference between the effectiveness of the preferred and unpreferred feedback types. This latter finding indicates that the preferred feedback can facilitate the development of the accuracy in L2 learners' writing more than the unpreferred feedback.
An improved methodology to evaluate crop salt tolerance from field trials

The salt tolerance of crops is commonly expressed in descriptive parameters such as threshold or 50%-yield soil salinity and shape parameters describing the yield curve. Estimation by visual or simplified ordinary least squares (OLS) regression methods has multiple issues: parameter bias due to uncertainty in soil salinity, lack of independent estimates of the reference yield, questionable robustness of the threshold parameter and missing information about uncertainty and correlation of the parameter estimates. Here, we present a comprehensive OLS method together with an analysis of its statistical properties to alleviate and overcome such issues, on the basis of a numerical experiment that mimics observed yield responses to saline groundwater across a range of salinities in the experimental test facility Salt Farm Texel. The results indicate under which experimental conditions bias is not a major problem. The method allows estimation of the zero-observed-effect yield from the data, which is relevant to agricultural practice. Estimates for zero-observed-effect yield and threshold ECe are negatively correlated, underlining the difficulty of obtaining reliable threshold values. The estimated confidence regions are reliable and robust against soil salinity uncertainty, but large observation error jeopardizes the confidence intervals, especially for the slope parameter. Data uncertainty alone can be responsible for substantial differences from experiment to experiment, providing a partial explanation for the wide variety in reported parameters in the literature, and stressing the need for long- term repetitions. Given the lack of robustness of the threshold parameter, we propose to adopt the 90%-yield EC (ECe 90 ) as tolerance parameter. Its confidence bounds can be obtained from a simple reformulation of the original models. We also present uncertainty ellipses as a suitable tool to unite multiple-year estimates. The method is offered as a solid and generic basis for reliable assessment of the cultivation potential of varieties and crops on salt-affected soils.

Space/Time Noncommutativity in String Theories without Background Electric Field

: The appearance of space/time non-commutativity in theories of open strings with a constant non-diagonal background metric is considered. We show that, even if the space-time coordinates commute, when there is a metric with a time-space component, no electric ﬂeld and the boundary condition along the spatial direction is Dirichlet, a Moyal phase still arises in products of vertex operators. The theory is in fact dual to the non-commutatitive open string (NCOS) theory. The correct deﬂnition of the vertex operators for this theory is provided. We study the system also in the presence of a B ﬂeld. We consider the case in which the Dirichlet spatial direction is compactiﬂed and analyze the eﬁect of these backgrounds on the closed string spectrum. We then heat up the system. We ﬂnd that the Hagedorn temperature depends in a non-extensive way on the parameters of the background and it is the same for the closed and the open string sectors.
Human Dipeptidyl-peptidase I GENE CHARACTERIZATION, LOCALIZATION, AND EXPRESSION*

Dipeptidyl-peptidase I, a lysosomal cysteine protein- ase, is important in intracellular degradation of proteins and appears to be a central coordinator for ac- tivation of many serine proteinases in immune/inflam-matory cells. Little is known about the molecular genet- ics of the enzyme. In the present investigation the gene for dipeptidyl-peptidase I was cloned and characterized. The gene spans approximately 3.5 kilobases and consists of two exons and one intron. The genomic organization is distinct from the complex structures of the other members of the papain-type cysteine proteinase family. By fluorescence in situ hybridization, the gene was mapped to chromosomal region 11q14.1-q14.3. Analysis of the sequenced 5 (cid:42) -flanking region revealed no classical TATA or CCAAT box in the GC-rich region upstream of cap site. A number of possible regulatory elements that could account for tissue-specific expression were iden- tified. Northern analyses demonstrated that the dipep-tidyl-peptidase I message is expressed at high levels in lung, kidney, and placenta, at moderate to low levels in many organs, and at barely detectable levels in the brain, suggesting tissue-specific regulation. Among im-mune/inflammatory cells, the message is expressed at high levels in polymorphonuclear leukocytes and alveolar macrophages and their precursor cells. Treatment of lymphocytes with interleukin-2 resulted in a signifi-cant increase in dipeptidyl-peptidase I mRNA levels, suggesting that this gene is subjected to transcriptional regulation. The results provide initial insights into the molecular basis for the regulation of
University of Groningen Purification and characterization of an alcohol dehydrogenase from 1,2-propanediol-grown Desulfovibriostrain

The sulfate-reducing bacterium Desulfovibrio strain HDv (DSM 6830) grew faster on (S)and on (R, S)1,2-propanediol (μmax 0.053 h–1) than on (R)-propanediol (0.017 h–1) and ethanol (0.027 h–1). From (R, S)-1,2propanediol-grown cells, an alcohol dehydrogenase was purified. The enzyme was oxygen-labile, NAD-dependent, and decameric; the subunit mol. mass was 48 kDa. The N-terminal amino acid sequence indicated similarity to alcohol dehydrogenases belonging to family III of NAD-dependent alcohol dehydrogenases, the first 21 Nterminal amino acids being identical to those of the Desulfovibrio gigas alcohol dehydrogenase. Best substrates were ethanol and propanol (Km of 0.48 and 0.33 mM, respectively). (R, S)-1,2-Propanediol was a relatively poor substrate for the enzyme, but activities in cell extracts were high enough to account for the growth rate. The enzyme showed a preference for (S)-1,2-propanediol over (R)-1,2-propanediol. Antibodies raised against the alcohol dehydrogenase of D. gigas showed cross-reactivity with the alcohol dehydrogenase of Desulfovibrio strain HDv and with cell extracts of six other ethanol-grown sulfatereducing bacteria.
Elevated carbon dioxide and temperature effects on rooting behaviour of grape cuttings

elevated CO 2 condition are interface between the lithosphere and biosphere. Root health in crop plants a major sustainable productivity cope with changed climatic conditions. Keeping this in view the present research work was carried ABSTRACT An experiment was laid out to study the impact of eCO 2 (550ppm), eT (+3ºC) and their interaction (eCO 2 +eT) on rooting behaviour of cuttings of three grape varieties- Thompson Seedless, Bangalore Blue, and Dogridge in FATE and OTC facilities. Observations were recorded at 50 and 80 days after planting (DAP) and root growth data was recorded and analysed using WinRHIZO root scanner and its software. Analysis revealed that, among the selected grape varieties, Thompson Seedless cuttings has shown highest number of roots, root volume and dry biomass under eCO 2 and eCO 2 + eT conditions, while total root length and root length density were highest with Bangalore Blue. Under eT condition, Bangalore Blue showed highest number of roots, total root length and root length density, while root volume and dry biomass was highest with Thompson Seedless. The per se values of root parameters under all conditions and their response to eCO 2 was lowest with Dogridge. Though eT condition reduced all the root parameters, their performance improved under eCO 2 + eT indicating the presence of higher concentration of CO 2 reduced the ill effects of high temperature. Overall, eCO 2 and eCO 2 +eT conditions improved root parameters of grape varieties, while eT reduced them as compared to their performance under ambient condition and varietal variation is significant.
