Authors: Edibamode Ezon-Ebidor Innocent , Efiong Edet Iboro , Asiwe Nicholas , Gobour Cynthia Eben 
Published: March 2024

Background: Canities, or graying or whitening hair, is a natural part of aging caused by reduced melanin production. Premature canities occur in humans or animals at a young age, with factors such as genetics, lifestyle, and environmental influences contributing. The study aims to evaluate the relationship between ABO Blood type, rhesus Factor, Genotype, Lifestyle, and Premature canities.
Methods: 259 respondents were involved and a cross-sectional descriptive study design was used to generate data. The respondents were selected using a multi-stage random sampling techniques and data collection was via descriptive questionnaire. Data obtained were analyzed using IBM SPSS version 25.
Results: A study of 259 participants found no significant association between premature canities and ABO blood type, rhesus, and genotype while lifestyle factors like smoking, and alcohol intake showed an association. Canities were found in various head regions, with no differences between sexes. Smoking and alcohol intake were more common in males. Depression was negatively associated with non-premature and premature canities. Nutrition intake was similar, but high carbohydrate and vegetable consumption was found to be statistically different.
Conclusion: No association between ABO blood type, rhesus factor, genotype with premature canities, and lifestyle (alcohol intake and smoking) showed possible association with premature canities.

The primary objective of this multilocational study was to investigate the impact of NPKS granule and briquette fertilizers, on selected soil chemical properties and yield of maize. The treatments were made up of different rates of NPKS granules and briquette fertilizers namely: T1 (Control), T2 (Granule NPK 10- 20-20 (200 kg ha-1) + Granule Urea 217.2 kg ha-1), T3 (Granule NPKS 10- 20-20-3 (600 kg ha-1) + Granule Urea 87 kg ha-1 GrU), T4 (Granule NPKS 10- 20-20-3 (400 kg ha-1) + Granule Urea 87 kg ha-1 GrU), T5 (Granule NPKS 10- 20-20-3 (400 kg ha-1) + No Urea), T6 (Briquette NPKS 10- 20-20-3 (3 briquettes/hill) + Briquette Urea (2 briquettes/hill) and T7 (Briquette NPKS 10- 20-20-3 (3 briquettes/hill) + Briquette Urea (1 briquette/hill), were deployed in a randomized complete block design with four replications. Some soil chemical properties were assessed; pH, available phosphorus (P), exchangeable potassium (K), calcium (Ca), magnesium (Mg), cation exchange capacity (CEC), total nitrogen (N), and organic matter content. Findings revealed stable pH levels, low available P, and suboptimal exchangeable K levels in the soil, indicating that the treatment did not have any significant impact on the chemical properties of the soil. The application of Granular NPKS 10- 20-20-3 (400 kg ha-1) + Granular Urea 87 kg ha-1 GrU) to maize produced significantly higher cob length and cob diameter compared with the control at only Atebubu. Total grain yield exhibited no significant differences (P ≥ 0.05) among treatments at Atebubu and Nsapor respectively. Significant differences occurred in the 100-seed with T3 and T4 producing higher weights at Nsapor and Atebubu respectively. Although the differences between treatments were not statistically significant, the result indicate a potential positive effect of T3 and T5 on grain yield (t/ha). The study highlights the influence of NPKS fertilizers in granule and briquette forms on soil chemical properties and maize yield, with the granules performing better than the briquette hence recommended.

A field experiment was carried out at Department of Vegetable Science experimental block at College of Horticulture, Bagalkot during Rabi season of the year 2022-23 to study the influence of integrated nutrient management (INM) on growth and yield of brinjal. The experiment was laid out in Randomized Complete Block Design (RCBD) comprised of ten treatments with three replications. Organic manures like FYM and Vermicompost are used in different combinations along with inorganic fertilizers and biofertilizers. Among the different combinations of treatments, treatment T10 where 50% RDN supplied through inorganic fertilizer + micro nutrients Fe, Mn, Cu & Zn recorded higher growth parameters like plant height, number of primary branches, stem girth and plant spread (E-W) and (N-S) at 45 and at 90 DAT of brinjal and these growth parameters were lowest in treatment T5 where 75 per cent RDN through inorganic fertilizer + 25 per cent RDN through FYM and Vermicompost + Azotobacter + AM + PSB. The earliness parameters like number of days to first flowering, days to 50 per cent flowering and days to first harvest were lowest in T5 and were highest in treatment T10. The yield attributes like number of fruits per plant (63.91), fruit yield per plant (3.88 kg/plant), yield per plot (77.53 kg/plot) and yield per hectare (53.92 t ha-1) were significantly highest in treatment T5 and were lowest in T10. Hence the combination of organic and inorganic fertilizer like 75 % RDN through inorganic fertilizer + 25 % RDN through FYM and Vermicompost + Azotobacter + AM + PSB) could be recommended for the farmers for higher growth and yield along with enhancing crop productivity of brinjal with enhancing soil productivity.

Nonlinear reference tracking control of a gas turbine with load torque estimation
Authors: Pongrácz B. , Ailer P. , Hangos K. M. , Szederkényi G. 
Published: November 2007

AbstractInput–output linearization‐based adaptive reference tracking control of a low‐power gas turbine model is presented in this paper. The gas turbine is described by a third‐order nonlinear input‐affine state‐space model, where the manipulable input is the fuel mass flowrate and the controlled output is the rotational speed. The stability of the one‐dimensional zero dynamics of the controlled plant is investigated via phase diagrams. The input–output linearizing feedback is extended with a load torque estimator algorithm resulting in an adaptive feedback scheme. The tuning of controller parameters is performed considering three main design goals: appropriate settling time, robustness against environmental disturbances and model parameter uncertainties, and avoiding the saturation of the actuator. Simulations show that the closed‐loop system is robust with respect to the variations in uncertain model and environ‐mental parameters and its performance satisfies the defined requirements.

Thermal degradation of a phenolic resin, vegetable fibers, and derived composites
Authors: Zárate C. N. , Aranguren M. I. , Reboredo M. M. 
Published: November 2007

AbstractThe thermal degradation behavior of resol, several vegetable fibers (two types of cotton fibers, sisal and sugar cane bagasse) and derived polymer composites have been investigated using thermogravimetric analysis (TGA). The initial thermal degradation temperature TONSET, the temperature at the maximum degradation rate TDM, and the char left at 500°C corresponding to the crosslinked resol were higher than the values measured for the fibers and their composites. Thus, the addition of the fibers reduced the thermal resistance of the phenolic thermoset. The polymer and the fiber‐composites showed a complex degradation involving different thermal decomposition processes. For that reason, the DTG curves were deconvoluted and a phenomenological kinetic expression was found for each individual peak. The overall thermal decomposition curve was recalculated adding each degradation process weighted according to its contribution to the total weight loss. An increase in the activation energy corresponding to the cellulose degradation was observed in the composites, highlighting the protective action of the resin encapsulating the fibers. © 2007 Wiley Periodicals, Inc.

Effect of polymorphism of isotactic polybutene‐1 on peel behavior of polyethylene/polybutene‐1 peel systems
Authors: Nase Michael , Androsch René , Langer Beate , Baumann Hans Joachim , Grellmann Wolfgang 
Published: November 2007

AbstractThe effect of polymorphism of isotactic polybutene‐1 (iPB‐1) on the peel behavior of the specific peel system low‐density polyethylene/polybutene‐1 (LDPE/iPB‐1) was investigated using wide‐angle X‐ray scattering, calorimetry, and the T‐peel test. Melt‐crystallization of iPB‐1, initially, yields tetragonal form II crystals which transform as a function of time to trigonal form I crystals. The kinetics of transformation at ambient temperature follows an exponential function, and is completed after about 50–75 h. The presence of LDPE in the peel system does not affect the transformation kinetics. The structure of the crystalline phase of iPB‐1 controls the peel force which decreases by about 25% during the crystal–crystal transformation in a blend with 20m% iPB‐1. The reduction of the peel force depends linearly on the mass fraction of iPB‐1 crystals in the peel system which further evidences the correlation between the crystal–crystal transformation of iPB‐1 and the peel‐characteristics of LDPE/iPB‐1 blends. Isothermal reorganization of crystals of LDPE is excluded as reason for the change of the peel‐performance of LDPE/iPB‐1 blends, since it is 5 to 10 times faster than the decrease of the peel force, and crystal–crystal transformation of iPB‐1, respectively. © 2007 Wiley Periodicals, Inc.

Combined effect of the ΔPhe or ΔAla residue and the p‐nitroanilide group on a didehydropeptides conformation

Published: November 2007

AbstractTwo series of dehydropeptides of the general formulae Boc‐Gly‐X‐Phe‐p‐NA, Boc‐Gly‐Gly‐X‐Phe‐p‐NA, Gly‐X‐Gly‐Phe‐p‐NA·TFA, and Boc‐Gly‐X‐Gly‐Phe‐p‐NA, with X = ΔZPhe and ΔAla, were studied with NMR in DMSO and CDCl3‐DMSO, and with CD in MeOH, MeCN, and TFE. The NMR spectra measured in DMSO suggest that peptides with the ΔPhe residue next to Phe are folded whereas peptides with Gly between ΔPhe and Phe are less ordered. NMR spectra of ΔAla‐containing peptides indicate that these peptides are flexible and their conformational equilibria are populated by many different conformations. The CD spectra show that conformational properties of the peptides studied are distinctly influenced by a mutual position of the dehydroamino acid residue and the p‐NA group. They indicate that all dehydropeptides with the ΔPhe residue, Boc‐Gly‐ΔAla‐Phe‐p‐NA, and Boc‐Gly‐Gly‐ΔAla‐Phe‐p‐NA adopt ordered conformations in all solvents studied, presumably of the β‐turn type. The last two peptides exhibit surprising chiroptical properties. Their spectra show exciton coupling‐like couplets in the region of the p‐NA group absorption. This shape of CD spectra suggests a rigid, chiral conformation with a fixed disposition of the p‐NA group. The CD spectra indicate that Boc‐Gly‐ΔAla‐Gly‐Phe‐p‐NA and Gly‐ΔAla‐Gly‐Phe‐p‐NA·TFA are unordered, independently of the solvent. © 2007 Wiley Periodicals, Inc.

Vapor phase growth of GaN using GaN powder sources and thermogravimetric investigations of the evaporating behaviour of the source material
Authors: Kallinger B. , Meissner E. , Berwian P. , Hussy S. , Friedrich J. , Mueller G. 
Published: November 2007

AbstractThe growth of GaN from the vapor phase is a promising technique for producing both bulk GaN crystals and GaN layers. For establishing a growth method from the vapor phase the source material and reactor setup are of great importance. Highly pure and self synthesized GaN powder was chosen as source material. The evaporation behaviour of the GaN powder was studied by means of thermogravimetry (TG). A vertical growth reactor was set up according to the results of numerical simulations of the temperature distributions and flow patterns. Freely nucleated GaN platelets of some millimetres in length were grown. Furthermore, thin GaN layers were deposited directly on a sapphire substrate. This nucleation layer was successfully overgrown by low pressure solution growth. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
No control, no drive: how noise may undermine conservation behavior in a commons dilemma
Authors: Brucks Wernher M. , Van Lange Paul A. M. 
Published: November 2007

AbstractSometimes people may no longer engage in conservational behavior (e.g., to reduce emissions) because their attempts to do so have been thwarted by “negative noise”, or external forces that may cause otherwise cooperative intentions to translate into non‐cooperative action (e.g., strikes prevented to commute by public transport rather than by car). The purpose of the present research is to examine whether experiences with negative noise in a commons dilemma may undermine conservational motivation and behavior, even in a subsequent commons dilemma that is free of noise. Participants first interacted in a commons dilemma task—with noise versus without noise—in which the common pool was sustained versus deteriorating. Afterwards, participants were involved in an identical second task in the same pool size condition but noise‐free for everybody. Consistent with hypotheses, participants who faced noise and a deteriorating resource in the first task exhibited lower levels of conservation in the second task than did participants who were always acting free of noise. This pattern was mediated by a reduced motivation to preserve the common pool, suggesting that the experience of noise in combination with a decline in collective resources may especially undermine cooperative motivation and behavior.

When knowledge matters—differential effects of available knowledge in standard and basic anchoring tasks
Authors: Englich Birte 
Published: November 2007

AbstractThe present research examines whether anchoring effects—the assimilation of a numeric estimate towards a previously considered standard—depend on judges' available knowledge in the target domain. Based on previous research, I distinguish two types of anchoring effects. Standard anchoring is obtained if judges are explicitly asked to compare the anchor to the target. Basic anchoring results if the accessibility of the anchor is increased prior to judgments about the target. I expected that only basic but not standard anchoring is reduced by providing judges with judgment‐relevant knowledge. Using a standard versus basic anchoring paradigm, 112 participants were confronted with a high versus low anchor before estimating the average price of a German midsize car. Prior to this task, participants were provided with information about prices of cars (relevant knowledge) versus kitchens (irrelevant knowledge). Results demonstrate that this knowledge only influenced the magnitude of basic but not standard anchoring effects. This finding demonstrates that knowledge has differential effects in different types of anchoring. Copyright © 2007 John Wiley & Sons, Ltd.

Published: November 2007

AbstractPigeon racing appeals to many in Taiwan, due in part to the potential large financial gains based on illegal betting. The races are unregulated with frequent examples of fraud, such as substitution of one bird for a substandard one. There is no test available to reliably verify the bloodline of pigeons and thus help to resolve such disputes. In this study, we describe a multiplex PCR amplification system combining 7 STR loci and a chromo‐helicase DNA binding gene (CHD) marker for the identification of individual pigeons. The cumulative power of discrimination (CPd) of the 7 STR loci was 0.99999234 based upon our population study. The cumulative probability of paternity (CPP) when used in paternity testing of 17 pigeon families ranged from 97.36 to 99.99% and the combined probability of exclusion (CPE) was 0.9325 for these seven STR markers. The statistical data illustrates the potential of this system to be used in pigeon individualization and paternity testing. Furthermore, the established STR system could be also used in the other areas, such as ecology, population genetics, and avian breeding programs.

Published: November 2007

Abstractα1,6‐Fucose residues within the N‐glycan core structures were commonly observed in many glycoproteins. Our previous studies showed that aberrantly α1,6‐fucosylated glycoproteins might be associated with metastasis of hepatocellular carcinoma (HCC). Little is known about human normal liver tissues (HNLTs) in the literatures. In this study, a target glycoproteomic approach which consists of lectin‐affinity chromatography, 2‐DE, protein immunoprecipitation and lectin blot, and MALDI‐MS/MS, was utilized to screen physiologically α1,6‐fucosylated glycoproteins. Lens culinaris agglutinin (LCA)‐affinity glycoprotein profiles of HNLT were established and analyzed, which allowed identification of 53 proteins by MS analysis, including haptoglobin precursor, α‐enolase, etc. Gene ontology (GO) annotation proved that these proteins distribute predominately in organelle and play crucial roles in binding and catalytic reactions. The present methodology enabled the identification of all the specific subsets of glycoprotein, and the corresponding data could contribute to the finding of more aberrantly α1,6‐fucosylated glycoproteins related to liver diseases.
Preparative separation and purification of phenolic compounds from Canarium album L. by macroporous resins
Authors: He Zhiyong , Xia Wenshui 
Published: November 2007

AbstractBACKGROUND: Canarium album L. (also called Chinese olive) is a traditional medicine material in China, and phenolic compounds from C. album possess great pharmacological activities. To obtain high‐purity phenolics from C. album, a crude extract of C. album phenolics was prepared by ethanol extraction. The use of macroporous resins for further separation and purification of phenolics in the extract was studied.RESULTS: Through static adsorption and desorption tests, AB‐8 resin was chosen for the separation of phenolics because of its higher adsorption capacity and desorption ratio than other resins. Then, dynamic adsorption and desorption experiments were carried out on an AB‐8 resin packed column to obtain optimal separation parameters. The highest adsorption capacity of AB‐8 was achieved when variables including initial concentration (C0), feed flow rate and feed volume were 10 mg mL−1, 2 mL min−1 and 9 bed volumes (BV), respectively, and saturated resin was first washed with 5 BV of water to remove impurities, then a purified product containing more than 85% of C. album phenolics was obtained by desorbing the resin with 2.5 BV of 70% (v/v) aqueous ethanol at flow rate of 1 mL min−1, and the recovery of phenolics was up to 75%. In addition, five phenolic compounds in the product were identified as gallic acid, ellagic acid, corilagin, hyperin and kaempferol‐3‐glucopyranoside by UV and LC–ESI–MS analysis.CONCLUSION: The results in this study could provide scientific references for the large‐scale production of phenolics from C. album.

An advanced model for predicting clear‐air visibility
Authors: Price J. D. 
Published: November 2007

AbstractThis article describes a new model to predict clear‐air visibility as a function of bearing with respect to the Sun. Its primary use is for aviation forecasting, and it is capable of providing estimates of visual range for any point along an aircraft flight path, using normal output from a numerical forecast model. It is also capable of forecasting line‐of‐sight visibility along airport approach paths. The model uses Mie theory to predict scattering from the direct solar beam into the line of sight, and combines this with a diffuse and Rayleigh component of the extinction coefficient to provide visual range estimates. The methodology is presented together with some examples of how visibility varies with solar bearing angle. © Crown copyright 2007. Reproduced with the permission of Her Majesty's Stationery Office.
