Maximal deviation of large powers in the Nottingham group
Authors: Aslan Tuǧba , Hegedüs Pál 
Published: October 2018

AbstractThe group of formal power series under substitution over𝔽p{\mathbb{F}_{p}}, the so-called Nottingham group, is a pro-pgroup so it is a metric space. The intertwining of these two structures is an important object of study. This paper is concerned with how the power map influences the distance of elements. Suppose thatd⁢(f,g)=d1{d(f,\,g)=d_{1}}whiled⁢(f,1)=d2≥d1{d(f,1)=d_{2}\geq d_{1}}. In this paper we provide a sharp bound ford⁢(fj,gj){d(f^{j},\,g^{j})}in terms ofd1,d2{d_{1},\,d_{2}}and the exponentj. This bound confirms a conjecture by K. Keating.

Abstract

Introduction
The fascin-1 protein is a cytoskeleton-like protein, which can prompt structural changes in cell membranes and affect the integrity of intercellular relations to promote invasion and metastasis of tumor cells. In this study, we researched the expression of fascin-1 in glioma.

Material and methods
The fascin-1 protein and mRNA were detected by immunohistochemistry and reverse transcription polymerase chain reaction (RT-PCR). Then, we analyzed the relationship between the expression of fascin-1 protein and the clinical pathological characteristics of patients with glioma. Finally, the fascin-1 protein expression status and prognosis of glioma patients were investigated.

Results
The fascin-1 protein was mainly located in the cytoplasm of cells from glioma. The high expression rate of fascin-1 protein in glioma tissue was higher than that of normal brain tissue. At same time, we found that high fascin-1 protein expression was significantly correlated with World Health Organization (WHO) grading of glioma patients. The results survival analysis suggested high expression of fascin-1 protein in glioma patients with a shorter survival time. Multivariate analysis showed that high expression of fascin-1 protein was an independent predictor of the prognosis of patients with glioma.

Conclusions
High expression of the fascin-1 protein indicates poor prognosis for glioma patients.
Indirect Instrumentalism about Political Legitimacy
Authors: Brinkmann Matthias 
Published: October 2018

AbstractPolitical instrumentalism claims that the right to rule should be distributed such that justice is promoted best. Building on a distinction made by consequentialists in moral philosophy, I argue that instrumentalists should distinguish two levels of normative thinking about legitimacy, the critical and applied level. Anindirectinstrumentalism which acknowledges this distinction has significant advantages over simpler forms of instrumentalism that do not.
Social media buzz created by #nanotechnology: insights from Twitter analytics

Published: October 2018

Abstract
The word “nanotechnology” has been exaggerated not only by media but also by scientist groups who have overstated the unforeseen benefits of nanotechnology to validate research funding. Even ecologists, who normally remain indulged in doom-and-gloom divinations, use this word to fuel their own motives. Such outcomes lead to widespread misinformation and an unaware public. This research work is a staunch effort to filter the Twitter-based public opinions related to this word. Our results clearly indicate more of positive sentiments attached to the subject of nanotechnology, as trust, anticipation and joy overweigh by many folds the anger, mistrust and anger related to nanotechnology.

Published: October 2018

Abstract
The study investigated the level of heavy metal contamination in plants {maize (Zea mays) and tomato (Solanum lycopersicum L.)} from thirty soil samples of three locations (Epe, Igun and Ijana) in the Ilesha gold mining area, Osun State, Nigeria. Total concentrations of As, Cd, Co, Cr, Cu, Ni, Pb and Zn were determined using atomic absorption spectrophotometry. Spatial variations were observed for all metals across the locations which was adduced to pH and the clay contents of the soils of each location. The results showed that heavy metals are more concentrated in the areas that are closer to the mining site and the concentrations in soil and plants (maize and tomato) decreased with increasing perpendicular distance from the mining site, indicating that the gold mine was the main sources of pollution. The mean concentrations of heavy metals in plants (tomato and maize) samples were considered to be contaminated as As, Cd and Pb respectively ranged from 0.6 - 2.04 mg kg-1, 0.8 - 5.2 mg kg-1, 0.8 - 3.04 mg kg-1 for tomato and respectively 0.60 - 2.00 mg kg-1, 1.50 - 4.60 mg kg-1 and 0.90 - 2.50 mg kg-1 for maize. These levels exceeded the maximum permissible limits set by FAO/WHO for vegetables. In conclusion, monitoring of crops for toxic heavy metals is essential for food safety in Nigeria.

Abstract
Tillage operations play an important role in soil manipulation processes. This paper aim to design a vibratory mechanism for agricultural tillage operation which would provide the desired motion and path to the cutting tool in the soil. A four-bar mechanism is designed through the principles of mechanism synthesis technique. The dimensions obtained are modelled and validated through MATLAB and MSC Adams to examine whether the tillage tool follows the required trajectory or not. Velocity and acceleration analysis are also studied for the designed mechanism. The study confirmed that the tillage tool followed the required sinusoidal path and completed the objective of vibratory tillage operation.

Abstract
A novel aggregation induced emission (AIE) active anthracene based dihydroquinazolinone derivative (probe 1) has been synthesized and characterized by means of spectroscopic methods. The photophysical properties of this probe have been investigated in solvents of different polarity display that fluorescence states are of intramolecular charge transfer (ICT) character. Probe 1 show clear AIE behavior in water/THF mixture on reaching water fraction 95%. The AIE behavior of probe 1 have been exploited for the detection of metal ions in aqueous solution which reveals high selectivity and sensitivity towards Cu2+ ions by colorimetrically and function as a chemosensor in a remarkable turn-off fluorescence manner. Further, the experimental results were investigated by computational means by optimizing the ground state geometries of probe 1 and probe 1-Cu complex using density functional theory (DFT) at B3LYP/6-31G∗∗ and B3LYP/6-31G∗∗(LANL2DZ) levels of theory. Intra-molecular charge transfer was observed in probe 1 while ligand to metal charge transfer (LMCT) for probe 1-Cu complex.
A Combination Method for Testing the Mechanical Properties of Ultra-Soft Fine-Grained Soils

Published: October 2018

Abstract
With the consumption of land resources and a shortage of land space, the exploration and use of the ocean have increased. However, a new type of geotechnical engineering problem has been encountered in the development of marine engineering: the problem of ultra-soft soils, such as the dredger fills extracted from sediments in coastal reclamation projects and submarine landslides formed by the movement of sediments. Ultra-soft soils usually have very low strength with high water content, and flow easily. These features enable ultra-soft soils with high water content to exhibit physical properties of both solids and fluids. Reliably testing their mechanical properties presents new challenges for the traditional geotechnical test methods. To address these problems, a test method is proposed that combines a full-flow penetrometer test for soils and a rheological test for fluids. Kaolin samples with water content between 110 % and 157 % (approximately two to three times the liquid limit of kaolin) are tested as an example, and a detailed description and verification of the combination test method are presented. The results show that the combination test method can reliably measure the undrained shear strength of an ultra-soft soil at a wide range of shear strain rates in a short time, which is difficult for traditional methods. The combination test method proposed in this study provides a new reference for mechanical property testing of ultra-soft soils and hazard assessments related to ultra-soft soils.

Published: October 2018

Abstract
This article proposes solutions for stiffness estimation of Double-D-shaped caisson foundations embedded in three different types of ground profiles (stiffness variation along the depth: homogeneous, linear, and parabolic). The approach is based on three-dimensional finite element analyses and is in line with the methodology adopted in the Eurocode 8—Part 5 (2004) lumped spring approach. The method of extraction of various stiffness values from the finite element model is described, followed by obtainment of the closed-form solutions. Parametric study revealed the nominal effect of the embedment length of Double-D caissons, and hence only the width and diameter effects are included in the suggested formulations. The obtained results are presented in terms of multiplication factors for Double-D caissons. Final impedance functions for a given width and diameter of a Double-D caisson can be conveniently estimated by multiplying the proposed functions to the circular shaft solutions available in literature. The applicability of the proposed formulations is demonstrated by considering a typical bridge pier supported by Double-D caissons. The proposed formulations require a minimum amount of input parameters and can be used during the tender design to arrive at the required geometry of such foundations.

This work was conducted at the Centro Universitario Regional del Litoral Atlántico (CURLA) at 15°47’north latitude and 86°50’ west longitude, 10 km west La Ceiba, Honduras. The ecosystem Is characterized as tropical rain forest having 2700 mm of rainfall per year and an average annual temperature of 27°C with 82% relative humidity. Soils in the region are characterized by having an average soil pH of 4.9, have low levels of available N and P, high levels of Fe and intermediate levels of Mn. A randomized complete block design was employed with 4 replications. Plot size was 2 x 3 m encompassing 3 rows. In each block three rates of biogas effluent were applied at 250,500 and 750 kg N/ha/year. An added check with zero effluent was also included. The grass was cut at the surface of the soil every 56 days and the application of effluent was made in split applications. The results indicate that these treatments increased yield at least 25 % above the check. In the first cuttings there was a tendency to decrease yields although final cuttings demonstrated increased yields. This same response was observed in plant protein, especially in the last cutting where a 48 % increase was obtained. The best treatmentrelative to forage production and protein content was found when 500 kg N/ha/year was applied.

Samples of cotyledons and whole black beans (Phaseolus vulgaris, Tamazulapa variety) were stored for 6 weeks at 37°C and 90% relative humidity conditions in order to establish the chemical and physical changes and the role of the seed coat in the hard-to-cook phenomena. After the storage period, samples of whole beans were divided In two sub-samples: one with the and other without the seed coat. These two samples and the cotyledons were analyzed forcooking time, water absorption, dietary fiber, tanic acid, soluble pectins and phytic acid. Cooking time of whole beans Increased from 99 to 480 minutes; for the cotyledons, this value Increased from 45 to 111 minutes. Cooking time of the dehulled bean, stored as a whole bean, increased from 45 to 103 minutes. Water absorption in whole beans and cotyledon decreased, although In cotyledons this was higher. No changes were observed in the dietary fiber content of the cotyledons and the beans dehulled after storage. However, in the whole grains neutral -detergent fiber decreased, while acid detergent fiber, cellulose and lignin did not have a significant change. On the other hand, soluble pectates decreased In the whole bean and cotyledon; tannin content as tanic acid decreased only In the whole beans. The data obtained suggest that the seed coat could play a significant role in the hard-to-cook effect before and during storage

Authors: Córdova Hugo S. 
Published: October 2018

Genotype by environment interactions are extremely important when evaluating cultivars developed for diverse environmental conditions. Differences in environments and years can change the relative ranking of genotypes across environments. Thus, it is necessary to incorporatestability parameters to properly define the adaptation ofcultivars to given environments. The objective of this study was to determine the adaptation of maize hybrids developed by National Programs and private seed industries in Central Aroerica and the Caribbean. Thirty six (36) hybrids were evaluated across 151ocations during 1989 throughout North and Central America. Cultivar, performance and yield stability was analyzed using AMMI and Eberhart and Russell models. Hybrid HB-85 from ICTA yielded 5.7 t/ha, outyielding the local check H-5 by 34 %. In addition, this hybrid had excellent husk cover and minimal ear rot, and proved adapted to both favorable and unfavorable environments. Hybrid P-8802 from Panama also showed similar performance. The AMMI model identified the hybrids MAX-309, P-8812, P-88222, HB-85 and HB-87 as the most stable. Hybrids HB-85, HB-87, and HB-83M showed stability of grain yield (β1= 1, Sdi = 0) across 34 sites and 2 years. Good progress has been achieved in the production of hybrids adapted to adverse abiotic and biotic stresses for the Central American and Caribbean region. It is sllggested that the use ofthese new hybrids be encouraged to increase the productivity of maize in the region.

A population of 59 accessions of pepper (Capsicum spp) from the Germplasm Bank ofthe Centro Agronomico Tropical de Investigacion y Ensenanza (CATIE) and two populations from the Genetic Resources Program of the Vniversity of Costa Rica (UCR) were evaluated. Field experiments were conducted at the Fabio Baudrit UCR Experiment Station in Alajuela. Trials were conducted during the months of January through September of 1989. Seedlings were established under greenhouse conditions and later transplanted in the field. The populations were characterized with data obtained from field experiments. Various quantitative and qualitative characteristics were related to one another using simple linear correlations. Qualitative characteristics were related using the Engel’s equation. Pulp thickness was positively correlated with fruit fresh weight (r=0.75), seed number (r=0.59) and fruit length (r=0.53); and negativelycorrelated with pungency (r=-0.42) and days to flower (r=-0.36). Fruit diameter was posit'ively correlated with seed number (r=0.62) and pulp thickness (r=0.72). Pulp thickness also was positively correlated with seed number (r =0.51). Using the relationships proposed by Engels, 21 pairs of characteristics were related. For example, the majority of the heaviest fruits were positively correlated with early maturing white flower plants.

Twenty four similar trials with corn were conducted throughout Central America during 1989 and 1990. The specific objectives were: i) to evaluate the effect of intercropping legumes with corn, ii) to establish P requirements in a system of intercropping corn with legumes, iii) to evaluate soil coverage by the legume as an indicator of a potential for erosion reduction and iv) evaluate weéd control in the intercropped system. The following legumes were tested: Stizolobium deeringianum Bort (mucuna), Vigna unguiculata L. and Canavalia ensiformis L. each one with P doses of 20 and 40 kg/ha. In general, the results obtained in 1989 were similar to those of 1990. The average corn yield for the different locations varied between 1.8 and 6.0 t/ha in 1989 and 1.0 and 5.6 t/ha in 1990, indicating the great environmental variability of the corn zones of Central America. The corn yield was always lower with legumes than without them, at the same rate of P to both years, C. ensiformis reduced the corn yield by 0.310 (±0.32) t/ha, V. unguiculata by 0.540 (±0.48) t/ha and S. deeringianum by 0.610 (±0.69) t/ha. The response to P was variable and depended on the year, the location and the legume. A positive response to P applied to corn without the legume was observed in both years. The was a positive response to P in corn intercropped with.§, deeringianumin 1982 in corn intercropped and with C. ensiformis in 1990. The legume evaluation as a mulch (average of 8 trials) indicate that at 30 days after the corn planting, V. unguiculata gave the best coverage with 62%, followed by C. ensiformis, with 38% and S. deeringianum with 35%.

The economical substitution of nitrogenous fertilizer by biological fixation by a leguminous covering under rotation systems with corn (Zea mays L.), is one of the agricultural research themeswith highest potential for developing technologies aimed to achieve a sustainable corn production in the tropics. An experiment was conducted during twoconsecutive corn cycles at Cuyuta-Guatemala, in order to quantify the equivalence of urea dos es and the N supplied by two legumes (Canavalia ensiformis L. and Mucuna deeringianum Bort). During the first cycle, the corn yield showed a significant response to the N-urea as well as to the incorporation of green manure. During the second cycle, the residual effect of the legumes on the corn yield was markedly lower and the differences among rotation systems depended on the N level and plant population. The rotation effect with green manure and its relation with the doses of urea approved the substitution of N-fertilizer by green manure. The main factors affecting the yield response under the different rotation systems were: doses of N-fertilizer, amount of N in the superficial biomass of the legume and the final plant population.

Published: October 2018

Psychometric scale for measuring self-efficacy is such a critical important component of strategies to improve healthy behaviour. Social cognitive theory incorporates outcome expectancy, but emphasizes self- efficacy, or a perception of oneself being capable of performing certain skills to attain some outcome. The theory behind this model builds from the research of Bandura (1977). Self-efficacy scales have been championed as a critical component in many health disease prevention oriented programmes. Maternal, environmental and behavioral factors have been recognized as additional important determinants behavior change modeled in such approach to provide sustainable intervention in promoting self-efficacy to perceived risks. Development of Mother Self-Efficacy scale to measure this ability is critical in Diarrhea prevention and sustaining desired interventions.
