A Simple, specific, rapid, precise and accurate UV Spectrophotometric method have been developed and Validated for determination of Metoprolol Succinate. Drug Metoprolol Succinate showed the absorption maxima in at 222 nm and was linear for a range of 5 µg/ml –25 µg/ml with correlation coefficient of 0.9993. The validation of the above proposed method was done by carrying out precision and accuracy studies. The percentage recovery at three different levels i.e. 50%, 100% and 150% was found to be 49.8%, 99.5% and 151.5% respectively. The analytical method showed good Intra precision (Repeatability) with relative standard deviation 0.672 % and Inter precision with relative standard deviation is 0.685% which is less than 2. The proposed method was validated for the parameter Specificity, Precision, Linearity and range, Ruggedness, Accuracy and recovery. Hence proposed analytical method for estimation of Metoprolol Succinate formulation drug by UV spectrophotometer in pharmaceutical can be applied for the routine quality control analysis.
Performance of ZnO nanoparticles for fire retardant and UV protection of pine wood

The aim of this paper was to investigate the influence of zinc oxide (ZnO) nanoparticles on the resistance of pine wood to fire and ultraviolet (UV) radiation. The ZnO nanoparticles were prepared from aqueous zinc nitrate via a proteic sol-gel method. Dried samples were impregnated using immersion in an aqueous solution of ZnO nanoparticles in the amount of 1 wt. % wood. Samples were exposed to an open flame to test the fire retardance, and a high-pressure UV lamp was used to test the UV resistance. The results showed an improvement in the fire retardance and UV radiation resistance after the impregnation of ZnO nanoparticles.

Determination of As, Cd, and Pb in Tap Water and Bottled Water Samples by Using Optimized GFAAS System with Pd-Mg and Ni as Matrix Modifiers

Arsenic, lead, and cadmium were determined in tap and bottled water samples consumed in the west part of Turkey at trace levels. Graphite furnace atomic absorption spectrometry (GFAAS) was used in all detections. All of the system parameters for each element were optimized to increase sensitivity. Pd-Mg mixture was selected as the best matrix modifier for As, while the highest signals were obtained for Pb and Cd in the case of Ni used as matrix modifier. Detection limits for As, Cd, and Pb were found to be 2.0, 0.036, and 0.25 ng/mL, respectively. 78 tap water and 17 different brands of bottled water samples were analyzed for their As, Cd, and Pb contents under the optimized conditions. In all water samples, concentration of cadmium was found to be lower than detection limits. Lead concentration in the samples analyzed varied between N.D. and 12.66 ± 0.68 ng/mL. The highest concentration of arsenic was determined as 11.54 ± 2.79 ng/mL. Accuracy of the methods was verified by using a certified reference material, namely, Trace Element in Water, 1643e. Results found for As, Cd, and Pb in reference materials were in satisfactory agreement with the certified values.
A Test of Independence in Two-Way Contingency Tables Based on Maximal Correlation

Maximal correlation has several desirable properties as a measure of dependence, including the fact that it vanishes if and only if the variables are independent. Except for a few special cases, it is hard to evaluate maximal correlation explicitly. We focus on two-dimensional contingency tables and discuss a procedure for estimating maximal correlation, which we use for constructing a test of independence. We compare the maximal correlation test with other tests of independence by Monte Carlo simulations. When the underlying continuous variables are dependent but uncorrelated, we point out some cases for which the new test is more powerful.

Effect of Toluene and Dioctylphthalate on the Rebar Corrosion of Medium Carbon Steel in Seawater and Cassava Fluid

Chemical mitigation is regularly used as one of the principal prevention and control techniques in reinforcement corrosion. Hence this study presents the effect of toluene and dioctylphthalate on the rebar corrosion of medium carbon steel in seawater and cassava fluid with a view to determining inhibitive potentials of the different inhibitors in the two media. Gravimetric and voltametric techniques were employed in this study and a total of forty-five corrosion coupons of different dimensions were produced. Forty coupons were used for gravimetry and the remaining five for corrosion potentials measurements. Eight of the samples were used as control; while other eight samples were admixed with dioctylphthalate and toluene in concrete cubes. It was later immersed in seawater and cassava fluid for a total duration of 32 days and the measurements were taken at interval of 4 days in order to determine the corrosion rates in mils per year (mmpy). Two controls and admixed samples were later immersed in seawater and cassava fluid, respectively, for durations of thirty-two days to determine the corrosion potentials using a voltmeter and a Copper-Copper Sulphate Electrode (Cu/CuSO4). The pH of each medium was also measured throughout the period of exposure. The results obtained showed that all the samples except the control samples, displayed some degree of inhibition. The inhibition levels for the admixed samples in seawater were on the higher side compared with those in cassava fluid. The inhibition efficiencies for different inhibitors followed different trends in different environment. The inhibition efficiencies for toluene in cassava fluid and seawater were 21.64% and 45.78% respectively. The study concluded that organic inhibitors were effective in inhibiting corrosion in cyanide and chloride contaminated concrete cubes.

Multinational supermarket chains in developing countries: Does local agriculture benefit

There is no consensus in the empirical literature on how entry of multinational supermarket chains affects farmers in developing countries. We quantify the dynamic effects of supermarket expansion on agriculture within a structural framework that clarifies the adjustment mechanisms involved. The model specification takes the potential productivity linkage between supermarkets and local suppliers into account. While econometric analyses struggle with causality issues, we analyze the endogenous interaction between supermarkets’ choice of suppliers and agricultural productivity. Based on numerical simulations, two results emerge. First, we offer a possible understanding of the conflicting evidence in the empirical literature. Whether farmers benefit from supermarkets or get stuck in a low productivity trap depends on the extent of local constraints related to production capacity and market access. Second, supply chain development initiated by supermarkets can help farmers escape the low productivity trap. While supermarkets face a short run cost, they gradually gain from more productive local suppliers.
The psychological cost of saving – an agent-based modelling approach

In this paper, an alternative hypothesis to the standard economic models of saving is proposed, based on new research in behavioral and computational economic. The importance of traditional factors of influence for saving is acknowledged, but the explanatory spectrum is extended by focusing on the conformity variable. If each individual from a specific group may initially have a low propensity to consume (and implicitly a high propensity to save), under group dynamics and direct/indirect group pressure all the individuals may change their behavior, leading to a new group mainly characterized by a propensity to consume. The hypothesis was validated by using NetLogo simulations, finding that saving behavior is bind by a psychological cost which has the potential to switch the individuals’ focus from a saving philosophy centered on benefits, to a philosophy centered on costs.
Prolific plant regeneration through organogenesis from scalps of Musa sp cv. Tanduk

A prolific plant regeneration system using scalps derived from shoot tips of Musa spp. cv. Tanduk was developed. Highly proliferating scalps, produced after four monthly subcultures of shoot tip explant on Murashige and Skoog (MS) medium supplemented with 100 mM BAP and 1.0 mM IAA, were placed on MS basal medium supplemented with 1.0, 2.5 and 5.0 mM BAP. Rooting of shoots was assessed on hormone-free half strength and full strength MS media and on MS medium supplemented with 1.0, 5.0 and 10 mM IBA. Four types of potting media comprising of sand, peat, sand + top soil + goat dung (3:2:1 v/v) and top soil + sand (1:1 v/v) were evaluated during acclimatization of the plantlets. Prolific shoot regeneration from scalps was obtained on MS medium containing 2.5 mM BAP, at 9.61 and 40.6 shoots per explant after 4 and 8 weeks of culture, respectively. Meanwhile, the highest mean shoot height of 2.19 cm was attained on MS medium with 1.0 mM BAP after 8 weeks of culture. Full-strength MS medium supplemented with 5.0 mM IBA produced the highest mean number of roots per explant at 15.08, while the highest mean root length of 11.07 cm was obtained on hormone-free half strength MS medium at week 4 of culture. The highest plant survivability of 77.5% was achieved in potting medium consisting of top soil + sand + goat dung after 6 weeks of acclimatization. The plants were morphologically normal with vigorous stems and broad green leaves.
Sliding mode control of periodic review perishable inventories with multiple suppliers and transportation losses

The purpose of this paper is to develop robust and computationally eﬃcient supply chain management strategy ensuring fast reaction to the demand variations for periodic review perishable inventory systems. For that purpose, we apply a sliding mode approach and we propose a new discrete time warehouse management strategy. The strategy employs the sliding hyperplane appropriately designed to ensure a dead-beat performance of the closed loop system. Our strategy not only explicitly takes into account decay of goods stored in the warehouse (perishing inventories) but it also accounts for transportation losses which take place on the way from suppliers to the warehouse. The proposed strategy ensures full customers’ demand satisfaction, minimizes the on-hand inventory volume and prevents from exceeding the warehouse capacity. This reﬂects the need of simultaneous minimization of the lost sales costs and inventory holding costs. Furthermore, the strategy ensures that the ordered quantities of goods are always non-negative and upper bounded. These favourable properties of the proposed strategy are formally stated as a lemma and three theorems and proved in the paper.
The Limit Points of (Optimistic) Gradient Descent in Min-Max Optimization

Motivated by applications in Optimization, Game Theory, and the training of Generative Adversarial Networks, the convergence properties of first order methods in min-max problems have received extensive study. It has been recognized that they may cycle, and there is no good understanding of their limit points when they do not. When they converge, do they converge to local min-max solutions? We characterize the limit points of two basic first order methods, namely Gradient Descent/Ascent (GDA) and Optimistic Gradient Descent Ascent (OGDA). We show that both dynamics avoid unstable critical points for almost all initializations. Moreover, for small step sizes and under mild assumptions, the set of \{OGDA\}-stable critical points is a superset of \{GDA\}-stable critical points, which is a superset of local min-max solutions (strict in some cases). The connecting thread is that the behavior of these dynamics can be studied from a dynamical systems perspective.
Myth-busting and entrepreneurship policy: the case of high growth firms

Abstract Promoting high growth firms (HGFs) has become a strong fixation within enterprise policy. This is a debate article seeking to examine and challenge the mythology perpetuated by policy makers and embedded within high growth entrepreneurship policy frameworks. Within the article we argue that a number of distinctive ‘myths’ have become deeply embedded within these policy frameworks. Such myths have been built on misconceived preconceptions of HGFs, which has resulted in policy-makers taking a myopic view of these firms. A key aim of the paper is to highlight how false perceptions of HGFs translate into inappropriate policy interventions. The paper challenges some of the most commonly held myths about these firms (that they are predominantly young, small, high-tech, VC-backed, university spin-outs, who grow in an orderly organic fashion, operating similarly irrespective of location) and identifies a clear mismatch between how policy makers perceive HGFs and what they actually look like in reality. Suggestions for the design of future policy approaches are forwarded.
Profit-Driven Dynamic Cloud Pricing for Multiserver Systems Considering User Perceived Value

With the rapid deployment of cloud computing infrastructures, understanding the economics of cloud computing has becoming a pressing issue for cloud service providers. However, existing pricing models rarely consider the dynamic interaction between user requests and the cloud service provider, thus can not accurately reflect the law of supply and demand in marketing. In this paper, we first propose a dynamic pricing model based on the concept of user perceived value in the domain of economics that accurately captures the real supply and demand situation in the cloud service market. Subsequently, we design a profit maximization scheme based on the dynamic pricing model that optimizes profit of the cloud service provider without violating user service-level agreement. Finally, we propose a dynamic closed loop control scheme to adapt the cloud service price and multiserver configurations to the changes in cloud computing environment. Extensive experiments using data extracted from real-world applications validate the effectiveness of the proposed user perceived value-based pricing model and the dynamic profit maximization scheme. Our proposed profit maximization scheme achieves 31.32% and 22.76% more profit compared to two state of the art benchmarking methods, respectively.
The Effects of Organizational Support in Team Working on Creativity and Personal Initiative of Employees

Organizational support is one of the important dimensions of team working concept. The culture that will encourage employees to take the initiative and be creative requires top management support. The research question of this study is how organizational support exerts influence on take the initiative by team members and creativity of the employees. Therefore, this study aims to shed light on the relationship among organizational support, creativity and personal initiative. As a result of test of the hypotheses, positive and significant relationships between Organizational Support and Creativity and between Organizational Support and Personal Initiative have been supported. Managerial implications of these results are that if the employees feel the support of the management, they will be willing to take the initiative and they will unleash their creative potentials.
Controlled self-assembled nanoaeroplanes, nanocombs, and tetrapod-like networks of zinc oxide

We report on the controlled growth of novel self-assembled nanostructures (nanoaeroplanes, nanocombs, and tetrapod-like networks of zinc oxide) by a simple thermal evaporation technique in a single-stage furnace. Scanning electron microscopy and transmission electron microscopy are used to investigate their morphologies and structures. Shapes are regular and unit sizes vary from 80 nm to 5 µm. The relationship between the preparation conditions and the nanomorphologies in the experiments is helpful for controlling the physical properties of the nanosystems and, hence, is described in some detail. A possible growth mechanism is discussed.
Wählerstruktur im Wandel

Die ehemaligen „West-Parteien“ Union und SPD, aber auch FDP und Bundnis90/Die Grunen rekrutieren ihre Wahlerschaft auch heute noch eher in den alten Bundeslandern. Die Linke und die AfD haben im Osten eine starkere Basis. In den Grosstadten wird eher „links“ gewahlt, also SPD, Linke und Grune. Die Wahlerschaft der „alten“ Parteien (Union, SPD und FDP) ist uberdurchschnittlich alt. Frauen neigen eher zu den Grunen, Manner mehr zur Linken, zur FDP und insbesondere zur AfD. Bei der SPD hat sich die Wahlerstruktur stark von der Arbeiterschaft hin zu Angestellten und zu Personen im Ruhestand verschoben. Nicht zuletzt deshalb haben sich die Wahlerstrukturen von SPD und CDU/CSU aneinander angeglichen. Die Wahlerschaft der AfD weist dagegen einen hohen Anteil in der Arbeiterschaft auf, sowie an Beschaftigten mit eher einfachen Tatigkeiten. Die Praferenz fur eine Partei variiert auch mit der Hohe des Einkommens. Das Medianeinkommen der FDP-Wahlerschaft liegt weit oberhalb des gesamtem Medianeinkommens, gefolgt von der der Grunen und der der CDU/CSU. Das der SPD-Wahlerschaft befindet sich in etwa beim Median. Dahinter rangieren AfD und Linkspartei. Das Schlusslicht bilden jene, die nicht zur Wahl gehen wollen. Diese Gruppe hat auch am wenigsten am Einkommenswachstum der letzten 15 Jahre partizipiert. Entsprechend sind die Wahlerschaft der Linken und der AfD sowie die Nichtwahlerschaft unzufriedener mit ihrer materiellen Situation als die anderer Parteien; uberdies zeigen sie sich besonders besorgt im Hinblick auf gesamtgesellschaftliche Themen. Personlich fuhlen sich die meisten materiell gerecht behandelt, ein groser Teil empfindet aber die Gesellschaft als ungerecht.
Design of solid dosage forms for mucosal vaccination - Investigations on the influence of excipients on product performance

Most vaccines today are liquid formulations for parental administration. However, there are several drawbacks connected to these vaccines. Since injectable vaccines only induce systemic antibody responses, they are not effective against the various pathogens that affect mucosal surfaces with poor permeability for serum-derived antibodies, e.g. the small intestine. Further disadvantages of liquid injectable vaccines are the need for medical personnel for the administration, cold chain requirements and large packaging sizes, which all are especially negative factors in developing countries. Solid and preferably mucoadhesive vaccine formulations that are administered via mucosal surfaces would offer a good alternative to many of these problems. The aim of this thesis was therefore to study the influence of excipients in the design of such formulations regarding i) formulation-related properties (mucoadhesion and antigen release) and ii) antigen-functionality preservation during freeze-dying. Mechanistic and immunological investigations using mucoadhesive hydrophilic matrix tablets as potential formulations for sublingual immunization were performed. The effect of osmotic pressure differences on the adhesiveness of hydrophilic swelling matrix tablets was investigated and it was found that a decrease in the osmotic pressure difference resulted in a decrease in the adhesive force, i.e. the force required to detach the tablet from a wet surface. Release of the model antigen ovalbumin from hydrophilic matrix tablets and a fast releasing formulation was characterized. The Bradford Assay used for the protein quantification was found to be disturbed by the hydrophilic polymer Carbopol and a correction method was set up. Sublingual immunizations in BALB/c mice indicated a poor potential of all ER tablets to evoke intestinal immune responses, whereas an immediate release resulted in high antibody titres. Thus it was concluded that the latter formulation type should be preferred in sublingual immunization. In the second part of the thesis the stabilizing potential of different excipients during freeze-drying was tested on killed whole-cell Vibrio cholerae bacteria as a model vaccine for pathogens causing mucosal infections. Sucrose showed great potential to avoid bacterial aggregation, preserve important antigen structures and to maintain the immunogenicity of the bacteria. Hopefully, the presented findings are a help and inspiration for formulators and immunologists to develop mucosal vaccine formulations so that diseases for which today no vaccines exist can be prevented in all parts of the world.
