Combined effect of Zinc and Boron on yield and nutrients accumulation in corn

The event of partly grain-free ear is a crucial problem which can result in severe reductions in corn yield. In a two year field investigation, during 2003-2004, an experiment was conducted to determine the effect of boron (B) and zinc (Zn) application on yield and yield components of corn (Zea mays L.) plants grown in a B and Zn-deficient calcareous soil (fine, carbonatic, thermic, Typic Haploxerepts) of southern Iran. Treatments consisted of five levels of Zn (soil application of zinc sulfate at the rates of 0, 8, 16 and 24 kg ha and foliar spray of Zn solutions containing 0.3 weight percent of zinc sulfate) and four levels of B (soil application of boric acid at the rates of 0, 3 and 6 kg ha and foliar spray of B solutions containing 0.1 weight percent of boric acid). Zn and B solutions were applied at the rate of 1000 L ha. Zn and B fertilization significantly increased plant biological yield, grain yield, thousand grain weight, number of grains per stalk, grain protein content and the concentration of B and Zn in corn tissues. There was a significant B × Zn interaction on corn yield and tissue nutrient concentrations. In general, the effect of B × Zn interaction was synergistic on corn growth and yield. Although B and Zn fertilization made significant changes in some plant nutrients, the changes were slight enough not to affect plant growth and production. It was concluded that the event of partly grainfree ear in corn is proportionally related to B and Zn deficiency in calcareous soils of southern Iran. It can be recommended that in calcareous soils of southern Iran with low levels of available Zn and B, soil application of 1624 kg ha of zinc sulfate and foliar application of B solution containing 0.1 weight percent of boric acid (1000 L ha) may be applied for enhancement of grain yield and reduction of partly grain-free ear in corn. Further, it is recommended that more attention should be paid to Zn and B nutrition of corn plants in calcareous soils having low availability of these tow nutrients.
The Composition Effects of Tax-Based Consolidations on Income Inequality

Many advanced economies have recently embarked on fiscal austerity. As this has come at a time of high and rising income disparities, policy-makers have fretted about the inequality effects of fiscal consolidations. We shed new light on this issue by empirically investigating the (composition) effects of tax-based consolidations on income inequality, output and labour market conditions for a sample of 16 OECD countries over the period 1978-2012. We find that tax-based consolidations reduce income inequality, but at the cost of weaker economic activity. However, tax composition does matter. Indirect taxes reduce income inequality by more than direct taxes, possibly due to the operation of a positive labour supply channel. Higher indirect taxes increase the price of the consumption basket and create incentives for agents to increase their labour supply. We find this effect to be stronger for middle aged women. Looking at specific instruments, general consumption taxes and personal taxes are the most suited to reduce inequality while at the same time minimizing the equity-efficiency trade-off.
Multi-objective Operation Management of a Renewable Micro Grid with Back-up Micro Turbine/Fuel Cell/Battery Hybrid Power Source

As a result of today ’ s rapid socioeconomic growth and environmental concerns, higher service reliability, better power quality, increased energy ef ﬁ ciency and energy independency, exploring alternative energy resources, especially the renewable ones, has become the ﬁ elds of interest for many modern societies. In this regard, MG (Micro-Grid) which is comprised of various alternative energy sources can serve as a basic tool to reach the desired objectives while distributing electricity more effectively, economically and securely. In this paper an expert multi-objective AMPSO (Adaptive Modi ﬁ ed Particle Swarm Optimization algorithm) is presented for optimal operation of a typical MG with RESs (renewable energy sources) accompanied by a back-up Micro-Turbine/Fuel Cell/Battery hybrid power source to level the power mismatch or to store the surplus of energy when it ’ s needed. The problem is formulated as a nonlinear constraint multi-objective optimization problem to minimize the total operating cost and the net emission simultaneously. To improve the optimization process, a hybrid PSO algorithm based on a CLS (Chaotic Local Search) mechanism and a FSA (Fuzzy Self Adaptive) structure is utilized. The proposed algorithm is tested on a typical MG and its superior performance is compared to those from other evolutionary algorithms such as GA (Genetic Algorithm) and PSO (Particle Swarm Optimization).
On the relation between flows and performance in the mutual fund industry

We investigate the impact of past performance of fund flows using a data set that contains the net flows of mutual funds, as well as the two main components of net flows viz. new sales and redemptions. Using the fractional flow model of Sirri and Tufano (1998), we find that the relation is convex in the mid to high performance range due to the high sensitivity of new sales to good performance and concave in the low to mid performance range mainly due to the high sensitivity of redemptions to poor performance. We find a similar nonlinear flowperformance relation using the “change in market share” measure of Spiegel and Zhang (2013), contrary to their finding of a linear relation. Finally, we find a similar nonlinear flowperformance relation using measures of fund flows that are independent of fund size, namely a fund’s share of new sales to aggregate new sales and a fund’s share of redemptions to aggregate redemptions.
Analytical iterative multi-step interval forecasts of wind generation based on TLGP

Probabilistic wind power forecasting has become an important tool for optimal economic dispatch and unit commitment of modern power systems with significant renewable energy penetrations. Ensemble forecasting based on Monte Carlo simulation is commonly used by many grid operators, but other probabilistic approaches, such as multi-step iterative wind power forecasting have not yet been fully explored. The associated uncertainty analysis is an important yet challenging issue in this area. This paper proposes to use an analytic interval forecasting framework to estimate the forecasting uncertainty and its propagation with multi-steps for two wind farms based on the Temporally Local Gaussian Process (TLGP) model. The key findings confirm that TLGP forecasting not only has better accuracy but is also more reliable and sharp than other benchmark models. This work provides an innovative analytical framework for iterative multi-step interval forecasts.

Effect of JumpstartMD, a Commercial Low-Calorie Low-Carbohydrate Physician-Supervised Weight Loss Program, on 22,407 Adults

Background Commercial weight loss programs provide valuable consumer options for those desiring support. Several commercial programs are reported to produce ≥3-fold greater weight loss than self-directed dieting. The effectiveness of JumpstartMD, a commercial pay-as-you-go program that emphasizes a low-to-very-low-carbohydrate real-food diet and optional pharmacologic treatment without prepackaged meals or meal replacement, has not previously been described. Methods Completer and last observation carried forward (LOCF) of clinic-measured weight loss (kg) in 18,769 female and 3638 male JumpstartMD participants. Results Completers lost (mean ± SE) 8.7 ± 0.04 kg, 9.5 ± 0.04% with 44.5 ± 0.5% achieving ≥10% weight loss at 3 months (mo, N = 14,999 completers); 11.8 ± 0.1 kg, 12.6 ± 0.1% with 66.4 ± 0.6% achieving ≥10% weight loss at 6 mo (N = 11,805); and 11.5 ± 0.2 kg, 12.0 ± 0.2% with 57.6 ± 0.9% achieving ≥10% weight loss at 12 mo (N = 8514). LOCF estimates were −6.5 ± 0.03 kg, −7.2 ± 0.03% with 27.1 ± 0.3% achieving ≥10% weight loss at 3 mo; −7.7 ± 0.04 kg, −8.5 ± 0.04% with 36.3 ± 0.3% achieving ≥10% weight loss at 6 mo; and −7.7 ± 0.1 kg, −8.4 ± 0.1% with 34.6 ± 0.3% achieving ≥10% weight loss after 12 mo. Frequent health coach meetings was a major determinant of weight loss, with women and men attending ≥75% of their weekly appointments losing 8.8 ± 0.04 and 11.9 ± 0.1 kg, respectively, after 3 mo, 13.1 ± 0.1 and 16.5 ± 0.3 kg after 6 mo, and 16.5 ± 0.3 and 19.4 ± 0.8 kg after 12 mo. Phentermine and phendimetrazine had a minor effect in women only at 1 (6.1% greater weight loss than untreated), 2 (4.1%), and 3 mo (1.2%), but treated patients showed longer enrollment than nontreated during the first 3 (females: +0.4 ± 0.01; males: +0.3 ± 0.04 mo), 6 (females: +1.1 ± 0.04; males: +1.0 ± 0.1 mo), and 12 mo (females: +2.7 ± 0.1; males: +2.4 ± 0.2 mo). JumpstartMD produced generally greater weight loss than published reports for other real-food and prepackaged-meal commercial programs and somewhat greater or comparable losses to meal replacement diets. Conclusion A one-on-one medically supervised program that emphasized real low-carbohydrate foods produced effective weight loss, particularly in those attending ≥75% of their weekly appointments.
How Competitive is Croatia’s Banking System? A Tale of Two Credit Booms and Two Crises

V How Competitive is Croatia’s Banking System? A Tale of Two Credit Booms and Two Crises Abstract The paper provides an overview of competition in the Croatian banking market for the 1994-2016 period, updating some results from earlier work but also adding new estimates based on methodological improvements in the literature. While the CR(2) indexes of concentration remained fairly stable after 1998, privatization and acquisitions led to rapid growth of the three next largest banks, so that the CR(5) indexes rose. Other competition measures tend to mirror this, with competitive behavior falling somewhat, but not uniformly. We argue that the largest banks did not always take advantage of the market power they possessed for the purpose of increasing prices. Mark-ups estimated with the Lerner index increased, especially after the onset of the 2008 crisis, but increased margins were the result of marginal costs falling even faster than prices. We do find some association between higher mark-ups and greater inefficiency, creating some support for the “quiet life” hypothesis. However, the strong pace of marginal cost decreases and the passing on of lower costs (and better quality) to consumers, as well as the fact that prices already are at low levels, all temper this conclusion substantially.
Thiol disulfide homeostasis as oxidative stress marker in migraine patients

Migraine is a very common disease. Annual prevalence of migraine in our coun - try is reported as 16.4%. Oxidative stress is assumed to play a role in the patho - physiology of migraine. In many recent studies conducted on individuals with migraine, serum Oxidative Stress Index (OSI), Total Antioxidant Status (TAS), Total Oxidant Status (TOS) values were analyzed and it was indicated that the balance shifts towards oxidative direction. Thiol-disulfide homeostasis, which is an oxidative stress marker, was described in recent years and has been shown to have vital importance on cellular functions. In the light of this information, we aimed to examine the role of oxidative stress in pathogenesis of migraine disease with new biomarkers. The study was conducted on 36 cases of 24 pa - tients (17 female, 7 male; mean age: 40.54±11.60) followed up with a migraine diagnosis and 12 people in the healthy control group with similar age and sex (10 female, 2 male; mean age: 38.17±10.80). Total thiol (μmol/L), native thiol (μmol/L) and disulfide level, disulfide/native thiol, disulfide/total thiol, native thiol/total thiol ratios were quantified in the patient and control groups. In the migraine group with aura, reduced ratio and thiol oxidation reduction ratio val - ues were high and oxidized thiol ratio values were low (p = 0.010, 0.015, 0.048). This study focused on thiol-disulfide hemostasis, a new and reliable indicator in determining oxidative stress which is held responsible for the pathophysiology of migraine.
PART II DYNAMICAL MORPHOLOGY OF PROTON AURORA AND ELECTRON AURORA SUBSTORMS AND PHENOMENOLOGICAL MODEL OF MAGNETOSPHERIC SUBSTORMS 3. Diurnal Movement of the Location of Proton Auroras and Electron Auroras

3.1. Space-time diagrams of proton auroras and electron auroras From the records of meridian-scanning photometers, spatial distributions of auroral luminosity along the geomagnetic meridian were arranged as a function of local time, and the iso-intensity contour lines were drawn. These space-time diagrams of auroral luminosity give quantitative information about the dynamic behavior of proton auroras and electron auroras as shown by HIRASA WA and NAGATA (1972). Diagrams were given for Hμ and 01 5577 A emissions which are the typical emission lines in proton auroras and electron auroras, respectively. Assuming the auroral average height to be 100 km, the zenith angle is con­ verted to the horizontal distance from the zenith over the · observation point (Syow·a Station). This space-time diagram covers a wide range from 600 km north
A dimensionality reduction method to select the most representative daylight illuminance distributions

ABSTRACT One challenge when evaluating daylight distribution is dealing with the large amount of temporal and spatial data, visualizations and variability in illuminances that are assessed in buildings. Using a dimensionality reduction method based on principal component analysis, we identified the most representative annual daylight distributions. We modelled a rectangular room containing an analysis grid of 3200 illuminance sensor points and simulated 3285 different temporal daylight conditions using an annual occupancy schedule ranging from 08:00 to 17:00 with one-hour sampling intervals in two locations: Singapore and Oakland, California. Our approach explained 98% of the illuminance variability with three daylight distributions in Singapore, and 92% using six in Oakland, California. Our dimensionality reduction strategy was also generalized using a complex building geometry showing the utility of the method. We think this approach can be used to provide a more efficient and reliable method to analyse daylight performance in building practice. GRAPHICAL ABSTRACT
DETERMINANTS OF COMMERCIAL BANKS INTEREST RATE SPREADS: SOME EMPIRICAL EVIDENCE FROM THE EASTERN CARIBBEAN CURRENCY UNION

A trend analysis of commercial banks’ interest rate spreads in the Eastern Caribbean Currency Union (ECCU) over the period 1993 to 2003 exposes two stylised facts. First, spreads have been strong and persistently showing little signs of narrowing and second, foreign owned banks have been operating with larger spreads compared to their indigenous counterparts. This study employs panel data techniques to measure the relevance of micro and macro factors in determining commercial banks’ interest rate spreads over the period. The results indicate that the observed spreads can be attributed to the high level of market concentration, high operating costs and nonperforming loans and the central bank’s regulated savings deposit rate.

The Benets of Costly Voting

We present a costly voting model in which each voter has a private valuation for their preferred outcome of a vote. When there is a zero cost to voting, all voters vote and hence all values are counted equally regardless of how high they may be. By having a cost to voting, only those with high enough values would choose to incur this cost. Hence, the outcome will be determined by voters with higher valuations. We show that in such a case welfare may be enhanced. Such an e¤ect occurs when there is both a large enough density of voters with low values and a high enough expected value. JEL codes: C70, D72.
Cross-sectional Return Dispersion and the Payoffs of Momentum, Longer-run Contrarian, and Book-to-Market Strategies

We document a striking new regularity in the payoffs of momentum, longer-run contrarian, and book-to-market (B/M) stock strategies. Over our 1962 to 2005 sample, we find that the several month trend in the stock market’s cross-sectional return dispersion (RD) is substantially related: (1) negatively, to the subsequent change in 6-month momentum payoffs, (2) positively, to the subsequent change in 36-month contrarian payoffs; and (3) positively, to the subsequent change in both 6-month and 36-month high-minus-low B/M strategies. When decomposing each payoff-change into the forward-looking payoff and the lagged reference payoff, we find that the RDtrend is generally reliably related to both the forward-looking payoff (in the same direction as for the respective payoff-change) and the lagged reference payoff (in the opposite direction as for the respective payoff-change). We offer an interpretation which suggests that RD is a leading indicator of market-state changes and that market-state transitions are important for understanding the payoffs of momentum, contrarian, and book-to-market strategies.

Tibial stress fracture

Stres fraktur merupakan cedera yang sering terjadi pada kegiatan yang banyak melibatkan aktifitas fisik seperti pada atlet dan militer. Cedera ini sering terjadi pada ekstremitas bawah dan paling sering terjadi pada tulang tibia dibandingkan lainnya. Stres fraktur disebabkan oleh aktifitas berulang dimana aktifitas osteoblastik tertinggal dari aktifitas osteoklastik, sehingga tulang mengalami mikrofraktur selama aktifitas dan akhirnya mikrofraktur terkonsolidasi menjadi stres fraktur. Stres fraktur dapat dicegah dengan pemanasan sebelum kegiatan dan menaikkan frekuensi dan intensitas kegiatan sedikit demi sedikit. Terapi obat-obatan berupa antiinflamasi dan antinyeri, istirahat sampai bebas rasa sakit.

Hydrogen Sulfide Protects against Paraquat-Induced Acute Liver Injury in Rats by Regulating Oxidative Stress, Mitochondrial Function, and Inflammation

In addition to the lung, the liver is considered another major target for paraquat (PQ) poisoning. Hydrogen sulfide (H2S) has been demonstrated to be effective in the inhibition of oxidative stress and inflammation. The aim of this study was to investigate the protective effect of exogenous H2S against PQ-induced acute liver injury. The acute liver injury model was established by a single intraperitoneal injection of PQ, evidenced by histological alteration and elevated serum aminotransferase levels. Different doses of NaHS were administered intraperitoneally one hour before exposure to PQ. Analysis of the data shows that exogenous H2S attenuated the PQ-induced liver injury and oxidative stress in a dose-dependent manner. H2S significantly suppressed reactive oxygen species (ROS) generation and the elevation of malondialdehyde content while it increased the ratio of GSH/GSSG and levels of antioxidant enzymes including SOD, GSH-Px, HO-1, and NQO-1. When hepatocytes were subjected to PQ-induced oxidative stress, H2S markedly enhanced nuclear translocation of Nrf2 via S-sulfhydration of Keap1 and resulted in the increase in IDH2 activity by regulating S-sulfhydration of SIRT3. In addition, H2S significantly suppressed NLRP3 inflammasome activation and subsequent IL-1β excretion in PQ-induced acute liver injury. Moreover, H2S cannot reverse the decrease in SIRT3 and activation of the NLRP3 inflammasome caused by PQ in Nrf2-knockdown hepatocytes. In summary, H2S attenuated the PQ-induced acute liver injury by enhancing antioxidative capability, regulating mitochondrial function, and suppressing ROS-induced NLRP3 inflammasome activation. The antioxidative effect of H2S in PQ-induced liver injury can at least partly be attributed to the promotion of Nrf2-driven antioxidant enzymes via Keap1 S-sulfhydration and regulation of SIRT3/IDH2 signaling via Nrf2-dependent SIRT3 gene transcription as well as SIRT3 S-sulfhydration. Thus, H2S supplementation can form the basis for a promising novel therapeutic strategy for PQ-induced acute liver injury.

Participation of Adolescent Pupils in Recreational Activities with Greek Dances and Their Preference for Group Work at School

This paper aimed to study the adolescents’ preference from group work at school when participating in recreational activities with Greek dances. The sample of the research consisted of 280 adolescents, aged 12-13, divided into three groups as follows: 97 adolescents who had not dealt with any physical activity systematically, 84 adolescents who had only participated in physical activity programmes with Greek dances organized by secondary schools, and 99 adolescents who had participated in recreational activities with Greek dances organized by non-profit cultural societies. The measurement instrument was the first factor, “preferring group work”, from the questionnaire Feelings towards Group. Three measurements took place. For the statistical analysis of the data, the methods used were: analysis of the variance of two factors with one of them being repeated. Consequently, the adolescents’ participating in recreational activity programmes with Greek dances contributes to their preference for group work and developing positive feelings about it.
