Spectrophotometric speciation studies of two model melanin monomers

Field: Chemistry (Physical Sciences)

Melanins are important natural pigments synthesized by small molecules via various obscure oxidation and polymerization reactions. Eumelanin, one of the melanins found in mammals, colors hair and eyes, provides photoprotection, binds to metal ions, and provides antioxidant properties. The atomistic structures present in eumelanin are unknown because all melanins are amorphous and recalcitrant to chemical analysis. Here, in a bottom-up approach to studying eumelanin, redox active, polymerization-inhibited molecular subunits of eumelanin are observed in the presence of heavy metal centers and differing pH. The molecules focused on include 5,6-dihydroxyindole (DHI) and its oxidized form indole-5,6,-quinone (IQ). Although these molecules were first identified in the 1920s as probable eumelanin subunits, their properties are poorly characterized due to the tendency of DHI and IQ to rapidly polymerize. This study utilizes derivatives of these compounds that have bulky ‘blocking’ groups installed at key carbons, which prevent carbon- carbon bond forming reactions but allow redox changes to take place. The first steady-state spectrum of the semiquinone radical (SQ) species is presented via stabilization with Zn(II) ions. EPR measurements show that the addition of Zn(II) ions to a solution of DHI-Me and IQ-Me increases the population of radicals dramatically. These results show the ability of monomeric SQ to bind to heavy metals, while elucidating the contribution of SQ to the broadband absorption of melanin. Additionally, the first high precision measurement of the pKa of IQ is reported, utilizing global analysis. This value may allow for future speciation of substructures in melanin with an understanding of how IQ responds to changes in acidity. Results from this study further our understanding of melanin towards usage in complicated chemical environments in medical and renewable energy biotechnology.

VALUE APPROACH TO THE EVALUATION OF MANAGERS’ WORK EFFECTIVENESS

Field: Business, Management and Accounting (Social Sciences)

The problem of evaluation of the effectiveness and quality of work of managers arises from the fact that the owners community of the Russian business starts to feel ready for the transfer of management functions to employees. These trends are complicated by many reasons, among of which we should highlight the lack of objective methods of evaluation of managers’ work effectiveness. At the same time, there are rather reliable methods of evaluation in foreign practice, based on the objective financial data. In this regard, there is a need to adapt the tools and methods to the activities of Russian enterprises developed by foreign scientists and used by practices. And as is the customary in modern management, the main purpose of management of the company is the increase of its value and, as a result, the shareholders' welfare, calculation of the cost is becoming one of the main tools for the evaluation of the quality and efficiency of the managers’ work. In this paper, the technique of using one of the methods is given, which is based on the determination of the intrinsic cost of the business with the purpose of business management and control over the activity of managers
“It doesn’t make sense, but it actually does”

Field: Social Sciences (Social Sciences)

Abstract The focus group is typically defined as a form of research interview involving a group of people, facilitated by a moderator with prepared questions ( Puchta and Potter 2004 ). The purpose of focus groups is to elicit participants’ descriptions of feelings, opinions, perceptions, and attitudes concerning the topic. As in other interviews, focus groups lend findings that rely largely on the interactional contingencies and dynamics that occur within, and yet less work has focused on their interactional features. Using conversation analysis (CA), this chapter aims to respecify focus group interaction as a locus for participants’ locally, collaboratively and sometimes incongruently accomplished actions, specifically focusing on the contingency of participants’ discussion sequences. With data examples from focus groups that were conducted with Korean teachers of English (EFL) within a teacher development program evaluation context, this chapter outlines how participants make use of diverse interactional resources in collaboratively constructing responses. This analysis helps to illuminate the major findings of the focus groups.

The neutral beam (NB) shine-through profile is routinely monitored on the Large Helical Device (LHD) both to calibrate the port-through power of the NB and to evaluate the NB-deposition power to LHD plasmas. The profile is measured with a calorimeter (CM) array on an armor plate of the NB counter wall inside the LHD vacuum vessel.
Network modeling of an inclined and off-center microstrip-fed slot antenna

Field: Engineering (Physical Sciences)

This paper describes a general method for analyzing a microstrip-fed slot antenna with a view to developing an improved network model featuring an inclined and off-center slot. The network model consists of an ideal transformer, a radiation conductance, and extended slotlines terminated by short circuit. The transformer turn ratio can be calculated by combining the reciprocity theorem with the spectral-domain immittance approach. The radiation conductance is determined by the radiated power from the slot in the forms of space and surface waves in the spectral domain. Then network models corresponding to several variations of the antenna are described and the series impedances are computed,The computed results using the network model are compared with the rigorous solution and measurements and good agreements are obtained.
Restorative justice: a changing community response

Field: Social Sciences (Social Sciences)

Our purpose herein is to demonstrate how restorative justice continues to unfold globally and we explain how the use of a restorative justice ideology and intervention leads to a common alternative, not only in criminal justice institutions, but also within social agencies, such as elementary schools, and the related social support systems. We draw attention to this emerging trend via current research and resources that enable us to put forward a definition, theoretical background and list the characteristic traits of this alternative mode of life consequence. Finally, we argue that the use of restorative justice in schools is a focus that is really a paradigm shift within the landscape of the educational enterprise.
Analysis of the zwf-pgl-eda-operon in Pseudomonas putida strains H and KT2440

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

A 3.9-kb fragment of the genome of Pseudomonas putida H, containing the complete zwf-pgl-eda-operon, encoding glucose 6-phosphate dehydrogenase, 6-phosphogluconolactonase and 2-keto-3-deoxy-6-phosphogluconate–aldolase, respectively, and part of the divergently transcribed regulatory gene, hex R, was cloned and analyzed. The nucleotide sequences of these genes showed high similarities to the corresponding DNA sequences of P. putida KT2440 and also to sequences of Pseudomonas aeruginosa PAO1. Derivatives of strains H and KT2440, containing transcriptional lacZ fusions to Pzwf were generated and used to study the expression of these operons. In both strains, this operon was induced by carbohydrates such as glucose, gluconate, fructose and glycerol. The transcription rate of the zwf-pgl-eda-operon was found to be about three times higher in the KT2440 background than in strain H. In both strains the induction of the zwf-pgl-eda-operon by carbohydrates during growth on carboxylic acids was not affected by carbon catabolite repression.
Ethical Motives and Charitable Contributions in Contingent Valuation: Empirical Evidence from Social Psychology and Economics

Field: Economics, Econometrics and Finance (Social Sciences)

Contingent valuation of the environment has proven popular amongst environmental economists in recent years and has increased the role of monetary valuation in public policy. However, the underlying economic model of human psychology fails to explain why certain types of stated behaviour are observed. Thus, good scope exists for interdisciplinary research in the area of economics and psychology with regard to environmental valuation. A critical review is presented here of some recent research by social psychologists in the US attempting to explain stated behaviour in contingent valuation. Attitudinal scales have been used to analyse the role of ecocentric, biocentric and altruistic motives for giving. However, the research is shown to draw some potentially misleading conclusions and be unrepresentative of contingent valuation. Two recent economic studies using contingent valuation are then reported and shown to have identified non-economic motives for WTP. The complexity of value formation and expression is found to go far beyond that generally accepted by economic models. Greater consideration of the role played by attitudes and ethical considerations then becomes relevant to the interpretation of results being used in standard cost-benefit analysis and environmental policy.
Genetic analysis in ashwagandha [Withania somnifera (L.) Dunal]

Field: Agricultural and Biological Sciences (Life Sciences)

The present investigation was undertaken to decipher multivariate diversity, variability, genetic parameters and traits association in Ashwagandha (Withania somnifera (L.) Dunal), genotypes for the yield of a dry root, total alkaloids in root and agro-morphological traits. A total of 16 genotypes were evaluated at three experimental sites in Gujarat, India. A randomized complete block design with two replications was used to conduct the trial. Pooled ANOVA results showed highly significant differences (p < 0.001) among the genotypes (G), environments (E) and G x E interactions. Higher phenotypic and genotypic coefficient of variation values were recorded for yield and agro-morphological traits indicating variation and scope of improvement through selection based on phenotypes. Higher heritability associated with greater genetic advance for the majority of traits showed a prevalence of additive gene effect and thus, phenotypic selection will be more productive. Based on the similarity of traits within and between members of clusters, genotypes were divided into five clusters. The principal component analysis (PCA) showed that most of the differences (76.90%) were explained by the first four PCA. The correlation analysis implies that improving one or more components traits could result in enhancement in root yield and total alkaloid content in ashwagandha. Genetic variability was present for the traits under study in the tested genotypes. Hybridization of genotypes from different clusters could be able to yield new genotypes combining high yield and other desirable yield-contributing traits.

[Studies on the internal pressure of bone tumors and tumorous conditions. I. Pain and internal hypertension of bone lesions].

Field: Medicine (Health Sciences)

Internal pressure of bone tumors and tumorous conditions were measured in twenty patients. High pressure were frequently found in the patients with painful bone lesions while low pressures were common in the patients with no pain. High internal pressure may be a causative factor of aching bone pain at rest. It is suggested that venous obstruction without high internal pressure is not a causative factor of bone pain in simple bone cyst.

Sequence-Structure Alignment Using a Statistical Analysis of Core Models and Dynamic Programming

Field: Computer Science (Physical Sciences)

The expanding availability of protein data enforces the application of empirical methods necessary to recognize protein structures. In this paper a sequence-structure alignment method is described and applied to various Ubiquitin-like folded Ras-binding domains. On the basis of two probability functions that evaluate similarities between the occurrence of amino-acids in the primary and secondary protein structure, different versions of simple scoring functions are proposed. The application of the program ’PLACER’ that uses a dynamic programming approach enables the search for an optimal sequence-structure alignment and the prediction of the secondary structure.
Transient Optimization of Natural Gas Networks Using Intelligent Algorithms

Field: Engineering (Physical Sciences)

Compressor stations in natural gas networks should perform such that time-varying demands of customers are fulfilled while all of the system constraints are satisfied. Power consumption of compressor stations impose the most operational cost to a gas network so their optimal performance will lead to significant money saving. In this paper, the gas network transient optimization problem is addressed. The objective function is the sum of the compressor's power consumption that should be minimized where compressor speeds and the value status are decision variables. This objective function is nonlinear which is subjected to nonlinear and combinatorial constraints including both discrete and continuous variables. To handle this challenging optimization problem, a novel approach based on using two different structure intelligent algorithms, namely the particle swarm optimization (PSO) and cultural algorithm (CA), is utilized to find the optimum of the decision variables. This approach removes the necessity of finding an explicit expression for the power consumption of compressors as a function of decision variables as well as the calculation of objective function derivatives. The objective function and constraints are evaluated in the transient condition by a fully implicit finite difference numerical method. The proposed approach is applied on a real gas network where simulation results confirm its accuracy and efficiency.
Glucocorticoid regulation of mouse mammary tumor virus sequences in transgenic mice.

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

We have introduced a chimeric plasmid, pLTR2TK, containing the mouse mammary tumor virus (MTV) long terminal repeat (LTR) linked to the herpes simplex virus type 1 thymidine kinase gene into the mouse germ line by microinjection. In one mouse line, the thymidine kinase gene is appropriately expressed in the lactating mammary glands of heterozygous females; expression also occurs in the ovaries of these mice. In heterozygous males of this line, and in a male derived from another microinjection, transcription of these new germ line genes occurs in the testes and is specifically stimulated by glucocorticoid hormones. Thus, the MTV LTR may contain elements that allow its expression both in lactating mammary glands and in testicular tissue.
Manic behavior and asymmetric right frontotemporal dementia from a novel progranulin mutation

Field: Neuroscience (Life Sciences)

Mario F Mendez1–3 1Department of Neurology, 2Department of Psychiatry & Biobehavioral Sciences, David Geffen School of Medicine, University of California at Los Angeles, Los Angeles, CA, USA; 3Neurology Service, VA Greater Los Angeles Healthcare System, Los Angeles, CA, USA Abstract: Studies suggest a relationship of manic behavior and bipolar disorder (BD) with behavioral variant frontotemporal dementia (bvFTD). The nature of this relationship is unclear. This report presents a patient with initial manic behavior as the main manifestation of familial bvFTD from a novel progranulin (GRN) mutation. In contrast, there are other reports of a long background of BD preceding a diagnosis of bvFTD. A review of the literature and this patient suggest that manic symptoms result from damage to right frontotemporal neural structures from longstanding BD, as well as from bvFTD and other focal neurological disorders. In addition, there is a subgroup of patients with a probable genetic predisposition to both BD and bvFTD. Keywords: frontotemporal dementia, mania, bipolar disorder, progranulin mutation
Pengaruh Kepercayaan Konsumen dan Harga Produk yang Dimediasi E-WOM terhadap Keputusan Pembelian di Platform Shopee

Field: Business, Management and Accounting (Social Sciences)

This study aims to analyze the influence of consumer trust and product price, mediated by e-WOM (electronic word-of-mouth), on purchase decisions on the Shopee platform. A quantitative approach was used, with a sample of 75 undergraduate students living in boarding houses in the Special Region of Yogyakarta who shop on Shopee. Data were collected via questionnaires and analyzed using Structural Equation Modeling (SEM) based on Partial Least Square (PLS) with SmartPLS version 4. The results show that consumer trust and product price have a significant positive influence on purchase decisions, both directly and indirectly through e-WOM. This confirms the vital role of user reviews and recommendations in the decision-making process. The study provides strategic implications for e-commerce platforms and guidance for consumers.
Evolution of Trypsin Inhibitor Activity during Germination of Lentils

Field: Agricultural and Biological Sciences (Life Sciences)

The effect of light and seed rinsing during the germination of lentil seeds (Lens culinaris var. Vulgaris cv. Magda-20) on trypsin inhibitor activity (TLA) has been studied. TLA decreased progressively during germination, while hydration grade and light exposure had less influence on TIA. In general, there was no significant change in TLA after 3 days of germination, except when seeds were rinsed only once and the experiment was conducted in the dark, showing a 10% TLA decrease. Six-day germination produced TLA decreases from 7% to 18%. In this case, the number of rinses had no significant effect on the final TLA, but the activity of protease inhibitors was significantly higher in seeds illuminated for 6 h per day. Maximal TLA decreases were found in seeds germinated in darkness and rinsed daily. Under these optimum conditions, TLA first decreased slowly (12% loss of this activity after 6 days) followed by a faster decrease (up to 45% of control seeds values) after 10 days of germination.
Turner from the Tate: the making of a Master

Field: Arts and Humanities (Social Sciences)

Exhibition: Everyone, it would seem, 'loves a Turner'. Yet in Australia, the majority of us do not quite know why despite the fact that his name resonates so fervently. Many of us are generally familiar with one aspect of his practice - brooding landscapes, ships caught in tumultuous seas or the more abstract views radiating with golden light - but are unaware of the full extent and implications of his genius. 'Turner from the Tate' seeks to redress this uncertainty by detailing the master's development through the most comprehensive collection of his work - the Turner Bequest.
Multiple CR Spatiotemporal Compressive Imaging System

Field: Computer Science (Physical Sciences)

Higher spatial and temporal resolutions are two important performance parameters in an imaging system. However, due to hardware limitations, the two resolutions are usually mutually restricted. To meet this challenge, we propose a spatiotemporal compressive imaging (STCI) system to reconstruct high-spatiotemporal-resolution images from low-resolution measurements. For STCI, we also designed a novel reconstruction network for multiple compression ratio (CR). To verify the effectiveness of our method, we implemented simulation and optical experiments, respectively. The experiment results show that our method can effectively reconstruct high-spatiotemporal-resolution target scenes for nine different CRs. With the maximum spatiotemporal CR of 128:1, our method can achieve a reconstruction accuracy of 28.28 dB.
