Even within a store chain and format, supermarket outlets often exhibit substantial differences in selling surface. For chain managers, this raises the issue of correctly anticipating the promotion lift, and of profitably managing promotion activities, across these outlets. In this paper, we conceptualize why and how store size influences the category sales effectiveness of four promotional indicators (depth of the promotional discount, display support, feature support, and whether the promotion is quantity-based). We then estimate the net moderating effect on four product categories for 103 store outlets belonging to four chains. For each of the promotion instruments, we find the percentage sales increases to be lower in large stores. For instance, whereas a 10 % point increase in feature activity enhances category sales by about 1.64 % in a 700m2 store, this figure drops to only 1.03 % in a 1300m2 store a 59% reduction. This moderating effect is especially pronounced for discount depth, the relative sales lift from a typical price cut being about 78 % lower in the larger-sized (1300m2) outlet. However, since large outlets also have larger base sales, the picture changes when we consider absolute sales effects. The net outcome is that deeper discounts or quantity-based promotions do not systematically generate larger or smaller absolute sales bumps in large stores, whereas for instore displays and features, we obtain a clear positive (be it less than proportional) link between store size and absolute category sales lift. When it comes to margin implications, we show that large stores gain higher profit from price cuts than small outlets only as long as the retailer keeps part of the manufacturer discount to himself. Managers can use these insights to improve their promotional forecasts across outlets, as well as to tailor their mix of instruments to store selling surface.
Stochastic Analysis of Natural Circulation Decay Heat Removal of Sodium Cooled Fast Reactor based on Latin Hypercube Sampling

A stochastic analysis of uncertainty correlation between input variables and analytical result of a computational simulation has been performed in the present study. A natural circulation decay heat removal in a sodium cooled fast reactor is chosen as a target phenomenon. The Midpoint Latin Hypercube Sampling (MLHS) and the correlation ratio are used to evaluate the rank of input variables upon the phenomenon. A common uncertain factor among the input variables has also been considered in the random sampling. As a result, it is concluded that the uncertainty correlation can be evaluated with the present method even when the common uncertain factor exists in some input parameters.
ON THE SIGNIFICANCE OF THE EXCESS NUMBER OF STRONG Mg ii ABSORBERS OBSERVED TOWARD GAMMA-RAY BURSTS

The number of strong (equivalent width >1 Å) Mg ii absorbers observed toward gamma-ray bursts (GRBs) has been found to be statistically larger than the number of strong absorbers toward quasi-stellar objects (QSOs). We formalize this “Mg ii problem” and present a detailed explanation of the statistical tools required to assess the significance of the discrepancy. We find that the problem exists at the 4σ level for GRBs with high-resolution spectra. It has been suggested that the discrepancy can be resolved by the combination of a dust obscuration bias toward QSOs, and a strong gravitational lensing bias toward GRBs. We investigate one of the two most probable lensed GRBs that we presented in our previous work (GRB020405) and find that it is not strongly gravitationally lensed, constraining the percentage of lensed GRBs to be <35% (2σ). Dust obscuration of QSOs has been estimated to be a significant effect with dusty Mg ii systems removing ∼20% of absorbed objects from flux-limited QSO samples. We find that if ∼30% of the strong Mg ii systems toward QSOs are missing from the observed samples, then GRBs and QSOs would have comparable numbers of absorbers per unit redshift. Thus, strong gravitational lensing bias is likely to make only a modest contribution to solving the Mg ii problem. However, if the dust obscuration bias has been slightly underestimated, the Mg ii problem would no longer persist.
Parental Homework Completion and Treatment Knowledge During Group Parent–Child Interaction Therapy

The purpose of this study was to examine how parental homework completion, session attendance, and treatment knowledge influenced parenting practices and confidence in using learned skills during behavioral parent training (BPT). Parents of 54 preschoolers (Mage = 5.07, 82% Hispanic/Latino) with externalizing behavior problems participated in an 8-week group BPT program. Pre-and posttreatment measures included parent-reported parenting practices and a treatment knowledge quiz. Parental homework completion, or home practice of skills, was reported by parents and collected weekly. Increases in positive parenting and decreases in negative parenting were observed (Cohen’s d = .63 and .70, respectively), as well as increases in treatment knowledge (d = 1.46). Treatment knowledge moderated the association between parental homework completion and negative parenting as well as parenting skill-use confidence. Increased parental homework completion was only associated with decreases in negative parenting and increases in skill-use confidence for families with high treatment knowledge. Parental homework completion also moderated the association between session attendance and negative parenting, such that lower session attendance was only associated with higher negative parenting for families that had low parental homework completion. Findings highlighted the potential impact that parents’ reports of home practice may have on improving parenting.
Control of Multiple-UAV Conveying Slung Load with Obstacle Avoidance

Quadrotor Unmanned Aerial Vehicles (UAVs) are generally underactuated systems and when load is attached for transportation purposes, the system complexity increases. Therefore, the need to appropriately control such systems becomes paramount as they usually navigate in cluttered environments. In this work, we conceptualize the problem of cooperative tracking control for a Multi-agent UAV load system (MUAVLs) whereby each UAV is divided into global position and local attitude subsystems. To ensure that formation is maintained in a desired path, Neural Network Graph-theoretic Distributed Adaptive Control (NNGDAC) is used for the position subsystem with a modified virtual force artificial potential field for obstacle avoidance. Another Adaptive Feedback Linearization (AFBL) controller is also designed for the attitude subsystem which is verified by simulation results.
Aggregate Feasible Region of DERs: Exact Formulation and Approximate Models

The aggregation of distributed energy resources (DERs) draws much attention since their penetration increases continuously. We derive the mathematical formulation of the exact aggregate feasible region (AFR) of multiple DERs. The derivation is based on analyzing the redundancy of all possible constraints in the Fourier-Motzkin Elimination (FME) process. In the exact AFR model, the number of constraints is regardless of the number of DERs but exponential with the number of time intervals. Although the computational complexity of the exact AFR is dramatically simplified compared with the original FME, there are still too many constraints for the exact AFR model to be applied in practice. Hence, we propose the $k$ th-order approximate models and two types of multi-timescale approximate models. Illustrative cases show the necessity of each constraint in the proposed models compared with the aggregated power and energy boundary model. Numerical simulations verify the accuracy of the exact AFR model. Besides, the second-order approximate model performs best considering the balance between accuracy, economics, and computational complexity.
Implementation of White Rot Fungal Pretreated Rice Straw for Sustainable Bioethanol Production by Saccharomyces Cerevisiae

This study presents the amount of bioethanol produced from rice straw pretreated with white rot Fungi, Pleurotus ostreatus, by Separate Hydrolysis and Fermentation (SHF) method using yeast. Rice straw was an attractive lignocellulosic material for bioethanol production since it is one of the most abundant renewable sources in India. The pretreatment of biomass is necessary to remove the surrounding matrix of lignin prior to enzymatic hydrolysis of cellulose to glucose and fermentation of glucose to ethanol. The rice straw was biologically pretreated with white rot fungi, Pleurotus ostreatus, for 44 days to degrade the lignin matrix. During the pretreatment, 27.85% of lignin and 24.30% of cellulose was degraded in 24 days. Results were justified from the structural changes observed before and after the pretreatment, evaluated by SEM and FT-IR studies. Maximum amount of glucose was released during hydrolysis at optimum conditions such as pH 4.5, temperature 50°C and incubation time 36hrs. The amount of ethanol produced from white rot fungal pretreated rice straw by Separate Hydrolysis and Fermentation using saccharomyces cerevisiae after 3 days of fermentation was 2.3% (v/w).
Links between leaf anatomy and leaf mass per area of herbaceous species across slope aspects in an eastern Tibetan subalpine meadow

Abstract Leaf anatomy varies with abiotic factors and is an important trait for understanding plant adaptive responses to environmental conditions. Leaf mass per area (LMA) is a key morphological trait and is related to leaf performance, such as light‐saturated photosynthetic rate per leaf mass, leaf mechanical strength, and leaf lifespan. LMA is the multiplicative product of leaf thickness (LT) and leaf density (LD), both of which vary with leaf anatomy. Nevertheless, how LMA, LT, and LD covary with leaf anatomy is largely unexplored along natural environmental gradients. Slope aspect is a topographic factor that underlies variations in solar irradiation, air temperature, humidity, and soil fertility. In the present study, we examined (1) how leaf anatomy varies with different slope aspects and (2) how leaf anatomy is related to LMA, LD, and LT. Leaf anatomy was measured for 30 herbaceous species across three slope aspects (south‐, west‐, and north‐facing slopes; hereafter, SFS, WFS, and NFS, respectively) in an eastern Tibetan subalpine meadow. For 18 of the 30 species, LMA data were available from previous studies. LD was calculated as LMA divided by LT. Among the slope aspects, the dominant species on the SFS exhibited the highest LTs with the thickest spongy mesophyll layers. The thicker spongy mesophyll layer was related to a lower LD via larger intercellular airspaces. In contrast, LD was the highest on NFS among the slope aspects. LMA was not significantly different among the slope aspects because higher LTs on SFS were effectively offset by lower LDs. These results suggest that the relationships between leaf anatomy and LMA were different among the slope aspects. Mechanisms underlying the variations in leaf anatomy may include different solar radiation, air temperatures, soil water, and nutrient availabilities among the slope aspects.
Analysis of Pesticide Residue in Coconut Water and Tomatoes around Tirupati Region by Using Reverse Phase Ultra High Performance Liquid Chromatography

During the last decades, the increasing demand of food safety gave rise to research regarding the risk associated with consumption of food stuffs contaminated by pesticides. Pesticides are widely used during the growth process of vegetables and fruits even after harvest. Therefore pesticide residue analysis is of overriding importance not only for the protection of human health but also for trade and regulatory control [1]. Tomato is a basic ingredient of the Mediterranean diet and is used almost daily in several countries for homecooked or processed as canned products. But a significant oncogenic risk has been associated to this crop considers the possibility of contamination by fungicides. Metalaxyl [n-(2,6-dimethylphenyl)-n-(methoxy-acetyl)-dl-alanine ester] is an acylalanine compound used as systemic fungicides it can be used to control diseases caused by air and soil borne peronosporales [2]. Coconut water is a clear isotonic, refreshing drink and rich source of nutrients, electrolytes, chlorides, potassium and moderate amount of sugar. Coconut water is ideal in preventing dehydration especially in children an increasing international demand for this product could be a highly positive issue. Current research on coconut water is specific uses, biochemical composition and preservative techniques. Coconut palms are very frequently attacked by various insects/pests and the total productivity is reduced hence to improve production of coconuts, the use of organophosphorus pesticides mainly monochrotophos (acts as cholinesterase inhibitor) is recommended. The injection of pesticides into trunk of the coconut trees cause contamination of coconut water and kernel by monocrotophos [3]. And coconut fruit is attacked by a number of phytophagous insects among different products used for the pest control, carbofuran belong to the chemical class of n-methyl carbamates is commonly employed in the coconut culture because it is an acetyl cholinesterase inhibitors [4] these studies indicate that the coconut water can be contaminated with pesticide residues by either way of treatment. The presence of pesticide residues in coconut water may constitute a health risk to the consumers due to their potency to cause toxicity. Hence, the pesticide residues in coconut water need to be monitored periodically from the consumer’s safety point of view. UHPLC with PDA is employed for identification and determination of metalaxyl, monochrotophos and carbofuran.
Association of Waist-Height-Ratio, Waist Circumference, and Body Mass Index with Serum Testosterone Level in Apparently Healthy Men

Previous studies have shown that waist circumference (WC) may be a better predictor of serum testosterone level than body mass index (BMI). The determination of the waist-to-height ratio (WHt ratio) is reported to have certain advantages over other adiposity measures. Our study thus aimed at examining the utility of WHt ratio in addition to WC and BMI in determining their association with testosterone level. The case-control study involved apparently healthy male participants aged between 40 to 60 years. The study participants were divided into normal and abnormal groups according to WC, BMI, WHt ratio with their mean total testosterone level compared. The correlations of total testosterone and adiposity measures along with age adjustments were also determined. Individuals with WC>100cm had a significant low (P=0.003) testosterone level compared to their counterparts with WC 25kg/m2 compared to the group with 0.5 had a significantly lower (P=0.012) testosterone than the group with <0.5. An inverse correlation of testosterone was observed with age (r=-0.567), BMI (r=-0.265), WC (r=-0.406), and WHt ratio (r=-0.412) in the apparently healthy Men studied. After adjustment for age, the correlation observed between testosterone and BMI (P=0.010), testosterone and WC (P=0.004), testosterone and WHt ratio (P=0.014) remained significant. After height adjustment, the correlation between testosterone and WHt ratio (P=0.002) also remained significant. In conclusion, the WHt ratio and WC independent of age were the best predictors of the total testosterone level in men.
PHYSIOLOGICAL AND NUTRITIONAL RESPONSES OF TWO DISTINCTIVE QUINCE ( CYDONIA OBLONGA MILL . ) ROOTSTOCKS TO BORON TOXICITY

The effects of excess boron (B) on some physiological and nutritional parameters of two distinctive quince (Cydonia oblonga Mill.) rootstocks were investigated. Throughout the world, B toxicity is a widely faced problem of soil in arid and semi-arid environments. In a greenhouse study, boron was applied at the rates of 0 and 40 mg kg soil to quince A and quince C rootstocks. Toxicity of B differentially affected studied parameters and rootstocks. Boron toxicity increased B concentrations of both rootstocks however the increase was more pronounced in quince A rootstock. SPAD readings, (SPAD-meter, Minolta 502 Co Ltd., Japan) as a measure of chlorophyll decreased under B toxicity. Boron toxicity increased membrane permeability and anthocyanin in both rootstocks. Although, there is rootstocks difference, lipid peroxidation (MDA) and proline and TAA (non-enzymatic total antioxidant activity) increased in response to B toxicity. In general, quince C had lower MDA (Malondialdehyde) and TAA but lower level of proline as compared to quince A. Boron toxicity did not affect the concentrations of P, Ca, Zn and Cu however increased B and Mn concentrations. Magnesium (Mg), Mn and Fe concentrations of quince were found higher than that of quince C. Indicating a genotypic effect, quince A and quince C responded to B toxicity differentially.
On the global attractivity of monotone random dynamical systems

Suppose that (θ,ϕ) is a monotone (order-preserving) random dynamical system (RDS for short) with state space V, where V is a real separable Banach space with a normal solid minihedral cone V + . It is proved that the unique equilibrium of (θ, ϕ) is globally attractive if every pull-back trajectory has compact closure in V.
Title B-MYB is essential for normal cell cycle progression andchromosomal stability of embryonic stem cells

Background: The transcription factor B-Myb is present in all proliferating cells, and in mice engineered to remove this gene, embryos die in utero just after implantation due to inner cell mass defects. This lethal phenotype has generally been attributed to a proliferation defect in the cell cycle phase of G1. Methodology/Principal Findings: In the present study, we show that the major cell cycle defect in murine embryonic stem (mES) cells occurs in G2/M. Specifically, knockdown of B-Myb by short-hairpin RNAs results in delayed transit through G2/M, severe mitotic spindle and centrosome defects, and in polyploidy. Moreover, many euploid mES cells that are transiently deficient in B-Myb become aneuploid and can no longer be considered viable. Knockdown of B-Myb in mES cells also decreases Oct4 RNA and protein abundance, while over-expression of B-MYB modestly up-regulates pou5f1 gene expression. The coordinated changes in B-Myb and Oct4 expression are due, at least partly, to the ability of B-Myb to directly modulate pou5f1 gene promoter activity in vitro. Ultimately, the loss of B-Myb and associated loss of Oct4 lead to an increase in early markers of differentiation prior to the activation of caspase-mediated programmed cell death. Conclusions/Significance: Appropriate B-Myb expression is critical to the maintenance of chromosomally stable and pluripotent ES cells, but its absence promotes chromosomal instability that results in either aneuploidy or differentiationassociated cell death.

Declarations of will in the digital environment and wrap contracts

Declarations of will made in a digital environment are undeniably different from the ones done in a "physical" world and some persons might not be aware of their significance. Many people join various Internet Service Provider's (ISP) sites daily. To do that, they usually have to agree to terms of service (ToS) that govern those sites. These declarations of will are sometimes direct: by clicking 'I agree', a person knows that he/she has agreed to ToS, whether he/she has read them or not. What is more important , a person is aware (or should be aware) that he/she has entered into some sort of an agreement with an ISP-a clickwrap agreement. However, on some Web pages, a person is consenting to the ISP's ToS simply by staying on and browsing the page, which constitutes a browsewrap agreement. These declarations are not direct and a person is often unaware that he/she has entered into an agreement with ISP. Furthermore, ToS often change and an ISP will sometimes not inform users about it. In those instances, users will not be aware of the changes to ToS and that, by continuing to use the ISP's services, they are agreeing to them. These are some examples of will being declared in a digital environment, without the person declaring it being aware of what he/she has done. It seems that, for some reason, people take what happens online less seriously than what happens in a "physical" world. This paper will try to show that this is a serious mistake in a digital environment.
Assessing the Potential to Change Stakeholders Knowledge and Practices on Fertilizer Recommendations in Africa

Africa’s fertilizer use averages only 8 kg per hectare per year. Available fertilizer recommenda-tions in Africa are high, and vary between countries. The recommendations are generally out dated, and/or “blanket” recommendations that are not site, or crop specific. Recommendation developed for one crop is often used for another and possibly unrelated crop. CABI and AGRA designed a project whose goal is “to help improve the capacity of National Research Institutions in developing fertilizer recommendations for efficient and profitable fertilizer use in 13 sub-Saharan African countries within the framework of ISFM practices under smallholder farming by the end of March 2016”. Baseline survey conducted in May 2014 targeted scientists, policy makers, extension workers, agro-dealers, fertilizer companies and farmers/farmer organization. Snowballing and convenience sampling techniques were used to get the sample and emails were used to reach the respondents. A total of 416 respondents were targeted but only 219 responded from 12 countries. Out of the 219, 148 were extension workers and researchers. About half (51%) of the scientists are aware of fertilizer optimization tool, and a lesser proportion have used the tool across all countries (31%). Fewer extension workers (31%) were aware of the fertilizer optimization tool and none reported to have used the tool. On average about 5% of the study participants reported that other stakeholders were involved in the development of fertilizer recommendations including farmers, farmer organizations, policy makers, researchers, extension workers, agro dealers, fertilizer companies and donor organizations. Stakeholder involvement was highest in Nigeria at 15%, followed by Ethiopia (13%) and Malawi (10%) but most of the countries reported <5%. There is a general understanding that development of fertilizer recommendations is a multi-stakeholder initiative and therefore need for involving many stakeholders in the development of fertilizer recommendations across Africa that will fosters greater ownership and sustainability.
