Ultrafast photochromism in metal-organic complexes by Paul-Franzl

Ultrafast photochromism in metal-organic complexes Paul-Franzl Xavier von Stein Department of Physics, University of Stellenbosch, Private Bag X1, Matieland 7602, South Africa. Thesis: MSc December 2016 Dithizone (H2Dz), an analytical reagent typically used in colourimetric analysis, reacts with various transition metals to form metal dithizonate complexes. These complexes display strong absorption in the visible region of the spectrum and exhibit photochromism: a photo-induced reversible transformation of the reactant to a product form with a distinctly di erent absorption spectrum. The photo-isomerisation of a C=N bond in the dithizone's backbone is responsible for this behaviour. This mechanism was con rmed in 2011 by the rst ultra-fast study on dithizonatophenylmercury(II) (DPM), a singleliganded complex. To compliment this study, transient absorption spectroscopy was used to capture temporally and spectrally resolved spectra of the photo-induced reaction in the dithizone ligand and select two-liganded dithizontates following excitation at their absorption maxima. The ligand, as well as the two-liganded Hg(HDz)2, Pb(HDz)2 and Zn(HDz)2 complexes showed two reaction paths following photo-excitation. The rst path is associated with an evolution along the rotational isomerisation coordinate which leads to product formation and ground state recovery with a time constant of ≈1 ps. This is in accordance to what was found for DPM. The second reaction path leads to a re-population of the ground state with a time constant of ≈10 ps. A physical process could not de nitively be assigned to the second pathway, although it is speculated that it may be due to an unstable intermediate along the C=N inversion coordinate. As the 1 and 10 ps paths were found to be intrinsic to the ligand, it was concluded that the second ligand does not participate in the dynamics, at least not on times below 500 ps. The Ni(HDz)2 complex was not analysed in detail due to complexities that arise given the possibility of ligand-ligand interactions and possible metal to ligand or ligand to metal charge transfer processes. ii Stellenbosch University https://scholar.sun.ac.za
Investigating the mediating role of cultural intelligence on the relationship between relational governance and firm social performance

The purpose of this research is to examine mediation relationship of cultural intelligence between the relational mechanism and firm social performance. This study based on a cross-sectional survey; data were collected using self-administered structured questionnaire from the senior managers working in manufacturing firms in the Pakistan. Structural equation modelling method was used to test confirmatory factor analysis, and mediation analysis was conducted with regression analysis using SPSS macro developed by Preacher and Hayes. This study demonstrates that cultural intelligence is a critical factor for joint planning and problem solving which promotes firm social performance. We found that individual with CQ tends to have cooperative norms and enable them to overcome hurdles in joint planning and perform well in resolving conflicts through investing more cognitive efforts. Cultural intelligence is aimed at facilitating relational governance to enhance joint planning and problem solving, involves a collaborative process to improve effectiveness and communication. Thus, CQ maintains more stable inter-firm relationship, help to acquire more knowledge on social issues, ultimately achieving more socially sustainable outcomes. Empirical findings suggest that cultural intelligence warrant consideration in developing successful social sustainable

Title : Enzymatic conversion of date fruit fiber concentrates into a new product enriched 1 in antioxidant soluble fiber

22 Soluble dietary fiber (SDF) has got increasing interest because of its prebiotic effects 23 and technological applications. The enzymatic hydrolysis is an effective treatment to 24 convert insoluble dietary fiber (IDF) into SDF. Date fiber concentrate (DFC) is a very 25 good source of dietary fiber, but its IDF/SDF ratio is very high. In this study an 26 enzymatic treatment has been optimized to enrich DFC in SDF: Viscozyme® L from 27 Novozymes A/S at 2.38 mL enzyme/100 mL reaction volume, in a solid/liquid ratio 1 28 g/35 mL, at 55o C during 30-60 min. In these conditions, the amount of SDF increased 29 from 1.8 to 6.3-5.4 g/100 g, and the ratio IDF/SDF changed from 19 to 2-3. In the SDF, 30 besides an increase in the antiradical activity, gluco-, manno-, and xylo31 oligosaccharides have been identified. Their molecular weights varied in a wide range, 32 depending of hydrolysis duration, which suggests that this enzymatic treatment could be 33 a promising process for obtaining tailor-made prebiotic oligosaccharides. 34 35
A Field in Flux: Exploring the Application of Computational Design Techniques to Landscape Architectural Design Problems

Landscape architectural design problems are under-served by the current canon of computational design techniques. More investigations into modeling landscape phenomena would improve the capabilities of designers working in this field. This paper introduces some of the problems specific to the intersection of computational design and landscape architecture through a case study in generating planting plans using parametric techniques. This illustrates issues of temporality, complexity, and dynamism that distinguish land form from built form alongside the opportunities and challenges found in adapting computation to the design of natural systems.
African and Arab American Achievement Motivation: Effects of Minority Membership.

The association between ethnic group identification, attributional style, and the use of self-protective attributions with respect to self-esteem, academic achievement and motivation among ethnically diverse adolescents was examined. Participants in the study included 422 African American, 90 Arab American, and 194 European American high school students. Results of this study indicated that ethnic minority students with a strong ethnic identity were more motivated to achieve academically and had a better school self-concept than students with a depreciated ethnic identity. An inverse relationship was found between academic achievement and variables measuring school self-concept and academic motivation among African American and Arab American students. In addition prejudice was frequently endorsed as a reason for failure among the ethnic minority participants. These findings suggest that some criteria, other than academic grades, are used for selfevaluation by ethnic minority adolescents. (Contains 90 references.)

Sliding-Mode Control Based MPPT for PV systems under Non-Uniform Irradiation

A fast and robust maximum power point tracking scheme with ability to track maximum power point (MPP) under partially shaded condition (PSC) is proposed for photovoltaic (PV) systems. The fast dynamics and robustness are attained by a sliding mode control and ability to track maximum power point under PSC by a MPPT algorithm with variable steps. In response to irradiance variations, the proposed algorithm recognizes shading and activates the scanning phase of the algorithm to find the global maximum power point (GMPP). In order to verify the accuracy and validity of the proposed method, different simulations are carried out in MATLAB-Simulink environment for various atmospheric conditions.
Optimism and Quality of Life after Renal Transplantation

Optimism is considered to influence Quality of Life (QoL) in a positive way. The longitudinal study was carried out to find the impact of optimism (life orientation) on perceived Quality of life among renal transplant recipients (RTRs) to see if optimism increases subjective QoL. The findings revealed a significant positive correlation between optimism and perceived QoL, suggesting that optimist recipients tend to be more satisfied with their overall life post- transplant. Recipients did not differ in levels of optimism on the basis of gender, marital status, education, financial conditions and time since transplantation. Age was the only demographic factor found to be negatively associated with optimism, suggesting that optimism decreases with increasing age. In order to clarify the cause & effect relationship, a linear regression was carried out that showed that optimism does not predict QoL; however, an increased QoL does predict optimism which is an interesting and unexpected finding. Optimism was studied as a personality trait; however, it appeared to be more as an outcome of life experiences. A Cross lagged Correlation analysis was carried out to clarify the causal direction of this relationship between optimism and QoL. However, no clear causal direction was found indicative of an overlap among these constructs which seem to lack distinctiveness as separate constructs.
Establishment of Japanese Organizational Citizenship Behavior Dimensions

The present study sought to identify Japanese employees’ behaviors that are considered organizational citizenship behavior (OCB). The authors presented the Japanese employees with a definition of OCB and asked them to list their behaviors that met the definition. On classifying those behaviors, seven Western dimensions and three Japanese dimensions were extracted. Although some of the Japanese dimensions seemed similar to the Chinese ones, upon close examination of the behaviors classified into the dimensions, it was revealed that they have unique aspects that reflect the Japanese culture. Some effects of the demographic factors on the employees’ responses were also empirically revealed.
Interactive comment on “ Uncertainty , sensitivity analysis and the role of data basedmechanistic modeling in hydrology ” by M . Ratto

We would like to thank the anonymous referee for his kind comments and for a stimulating review which raises a number of points that we would like to address below. General remarks 1. We agree with the referee that the two models considered in this paper are primarily intended to address different applications but we thought we had made this clear at various places in the paper. For instance, in the introduction we say, “The results of the exercise show that the two modelling methodologies have good synergy; combining well to produce a complete modelling approach that has the kinds of checks-and-balances required in practical data-based modeling of rainfall-flow sys-
Private Covariance Estimation via Iterative Eigenvector Sampling

We give a new method for computing a differentially private covariance matrix, suitable for use in a variety of regression settings, from a collection of user data. In contrast to previous methods, our approach has zero failure probability, and can be employed to compute the full matrix (not just the top k eigenvectors). As part of our analysis, we derive a precise expression for allocating the privacy budget among different components to minimize overall error. We then show empirically that our method outperforms previous state-of-the-art approaches, yielding lower error and better learning performance.
A general method for boosting the supercapacitor performance of graphitic carbon nitride/graphene hybrids

Graphitic carbon nitride (g-C3N4) contains a high C/N ratio of 3/4; however, utilizing nitrogen atoms in pseudocapacitive energy storage systems remains a challenge due to the limited number of edge nitrogen atoms and inherent poor electrical conductivity of this semi-conductor material. 3D oxidized g-C3N4 functionalized graphene composites (GOOCN24), in which reduced graphene oxide providing high electron conductivity acts as a skeleton and hybridises with oxidized g-C3N4 segments, were synthesized using a facile two-step solution-based method. Due to the pre-oxidation treatment of g-C3N4, which breaks the polymeric nature of g-C3N4 and increases in the proportion of edge nitrogen atoms and the subsequent solubility in water, the GOOCN24 composites used as electrodes for supercapacitors show a specific capacitance as high as 265.6 F g−1 in acid electrolyte and 243.8 F g−1 in alkaline electrolyte in three-electrode configuration at a current density of 1 A g−1. In addition, low internal resistance, excellent rate performance of over 74% capacitance retention (over a 50-fold increase in current density), and outstanding cycling stability of over 94% capacitance retention after 5000 cyclic voltammetry cycles in both alkaline and acid electrolytes was attained. This translated into excellent energy density with appropriate power density when demonstrated in a symmetrical device.
Dry matter and nitrogen uptake, partitioning, and removal across a wide range of soybean seed yield levels

Soybean [Glycine max (L.) Merr. ] growers are concerned that soybean yield is restricted by limitations on biological N₂ fixation and soil nitrogen (N) mineralization. However, a comprehensive study characterizing actual soybean N requirements across wide-ranging seed yield environments is nonexistent for modern soybean production systems. Using six site-years and eight soybean varieties, plants were sampled at six growth stages and partitioned into their respective plant parts and analyzed. For each kilogram increase in yield, total dry matter accumulation, harvest index, and total N uptake increased by 1.45 kg, 0.0034%, and 0.054 kg, respectively, but all varied by environment at any specific yield level, whereas N removal did not (0.055 kg N kg⁻¹ grain). Nitrogen harvest index (NHI) increased (0.0019–0.004% kg⁻¹ grain) with yield but varied by environment and yield level, resulting in indices between 73 and 90%. Peak uptake rates for N were 3.6 to 4.3 kg ha⁻¹ d⁻¹ between R4 and R5, depending on the yield level. After R5.5, 66 to 69% of vegetative N was remobilized to the seed, which accounted for 50.4% of seed N at the low yield level (3608 kg ha⁻¹), but only 38.9% at the high yield level (5483 kg ha⁻¹). Moreover, higher yields attained a greater portion of their total N uptake after R5.5 (40.1%) compared with the low yield level (29.7%). These results highlight greater remobilization efficiencies and late-season N uptake in conjunction with greater NHI to support higher yields per unit of N uptake in current production realities.
A Highly Efficient Dual-Mode 3G/4G Linear CMOS Stacked-FET Power Amplifier Using Active-Bypass

A highly efficient dual-mode linear CMOS stacked-FET power amplifier (PA) is implemented for 3G UMTS and 4G LTE handset applications. High efficiency is achieved at a backed-off output power (P out ) below 12 dBm by employing an active-bypass amplifier, which consumes very low quiescent current and has high load-impedance. The output paths between high-and low-power modes of the PA are effectively isolated by using a bypass switch, thus no RF performance degradation occurs at high-power mode operation. The fabricated 900 MHz CMOS PA using silicon-on-insulator(SOI) CMOS process operates with an idel current of 5.5 mA and show power-added efficiency (PAE) of 20.5%/43.5% at P out = 12.4/28.2dBm while maintaining an adjacent channel leakage ratio (ACLR) better than -39dBc, using the 3GPP uplink W-CDMA signal. The PA also exhibits PAE of 35.1% and ACLR E-UTRA of-33 dBc at P out = 26.5 dBm, using the 20 MHz bandwidth 16-QAM LTE signal.
Antioxidative and Hepatoprotective Effects of Lythrum salicaria

Several parts of Lythrum salicaria were used for this study. Scavenging activities on radicals, inhibitory activity on linoleic acid peroxidation and total phenol contents of extracts from root, flower, and aerial part were evaluated. Flower and root selected from in vitro assay were subjected to in vivo assay on -induced liver injury rat model for two weeks. Carbon tetrachloride intoxication on rats produced large amounts of hepatic lipid peroxidation product, thiobarbituric acid reactive substance (TBARS) compared with normal rats. Treatment with root extract of L. salicaria (LSR) showed effective inhibitory activity on lipid peroxidation product. Administration with LSR extract significantly alleviated -induced increase in GPT activity which were more effective than silymarin. The results of this study suggest that root and flower of L. salicaria have antioxidant and liver protecting activities, and root part is the most effective candidate to develop a new functional material.
Have Economic Reforms Affected Exchange Rate Pass-Through to Prices in India?

This paper examines the behaviour of exchange rate pass-through to domestic prices in India after the reforms initiated in the early 1990s. Unlike observed in several countries, it finds a rise in exchange rate pass-through to domestic prices until recent years. Besides economic factors typically associated with economic liberalisation, the persistence of higher inflation is an important factor for the rise in pass-through.
Mobile transect for identification of intra-urban heat islands in Uberlandia, Brazil

The “heat island” phenomenon is one of many serious problems caused by rapid urban growth. This study therefore sought to characterize and quantify heat islands in Uberlandia, to evaluate the seasonality of these islands (winter-summer) and to identify the effect of surface coverage on their intensity. To identify intra-urban heat islands in Uberlandia, air temperature data were collected in two seasons (winter and summer) using mobile and fixed transects seasons. Transition measurements were recorded automatically every 0.5 seconds using a car-mounted thermos-hygrometer moving at an average of 40 km h-1. GPS was used to select approximately ten data points every 500 meters of each transect. Fixed weather stations measured air temperature at three sites in the region. Transect data analysis showed that the intra-urban heat islands were more intense in winter (ΔT = 2.2ºC) than in summer (ΔT = 1.2ºC) mainly because by reduction in atmospheric vapor in winter (dry season) and by higher rate of radiative cooling that is favored in permeable areas. The methodology used in the present study proved to be a quick and efficient way to carry out this type of monitoring.
Clustering and multiple imputation of missing data

The present work specifically focuses on the data analysis as the objective is to deal with the missing values in cluster analysis. Two-Step Cluster Analysis is applied in which each participant is classified into one of the identified pattern and the optimal number of classes is determined using SPSS Statistics/IBM. Any observation with missing data is excluded in the Cluster Analysis because like multi-variable statistical techniques. Therefore, before performing the cluster analysis, missing values will be imputed using multiple imputations (SPSS Statistics/IBM). The clustering results will be displayed in tables. Furthermore, goal of analysis is to reduce biases arising from the fact that non-respondents may be different from those who participate and to bring sample data up to the dimensions of the target population totals.
Cell Adhesive Nanocomposite Materials Made of Carbon Nanotube Hybridized with Albumin

The authors have developed a biocompatible carbon nanotube (CNT) / albumin nanocomposite for 2D and 3D tissue organization by cell growth. The adhesion and proliferation of neuroblastoma and fibroblast cells have been investigated using films based on CNT / bovine serum albumin (BSA) nanocomposites. Singlewalled carbon nanotube (SWNT) / BSA composites could be used as a substrate for growing cells of different types. The properties of bulk nanocomposites (BNCs) produced under laser exposure have been compared with those manufactured using such techniques as heating, ultrasonic treatment and light-emitting diode (LED) effect. Stability, density, hardness and internal structure of BNCs have been analyzed. BNCs made under laser exposure were stable within several years. Density of nanocomposites prepared by all the methods was close to that of water. This fact is explained by high material porosity. Hardness of stable BNCs obtained by laser technique (~ 300 MPa) was significantly higher than that of unstable ones mentioned below. Stabilizing properties of the described laser based nano-manufacturing/forming of BNCs may be associated with the ability to obtain a nanotube scaffold in a composite structure under the action of the electric field of directed laser irradiation. The presence of such a scaffold can enable the self-assembly of biological tissues. Results of the study on the biological properties of the BNCs manufactured by the laser technique have pointed to the possibility of their application in surgical implants.
A structure for innovation reproduction in the Eclipse OSS ecosystem

In Open Source Software (OSS) development community supported by spontaneous volunteers, technical capabilities, hunger for fame and the satisfaction of contribution are said to be motivating factor for participation. In that community, vendors always play auxiliary roles, and integrate the result of OSS into their business activities. However, in the Eclipse OSS community, the main role of OSS development activities is taken over by vendors. The relationship between individuals and vendors is reversed. Therefore, it becomes important to maintain the motivation of the development community, promote innovation and link the activities to the profit of vendors. In other words, management of co-creation and competition are being conducted at the same time. This paper tries to clarify internal and external structures in an OSS ecosystem led by vendors considering the Eclipse community as one particular case. Also it constructs a co-creation model to promote sustainable development for an OSS ecosystem.
