Reinforcement Materials in Poly((R)-3-Hydroxybutyrate-co-(R)-3-Hydroxyhexanoate Bionanocomposite

Waste paper is the second-highest municipal solid waste collected in Malaysia and as current practice, it is recycled for further use in the manufacturing of low-grade products. Instead of continuously utilizing waste paper for low-grade products manufacturing, it can be used as a feedstock to produce high bioproducts such as cellulose nanofiber (CNF). Hence, this study explored the potential of waste paper as a feedstock for CNF production. The waste paper was subjected to a different number of cycles of wet disk milling (WDM): 0, 5, 10, 15 and 20 cycles. The presence of nano-sized cellulose was confirmed by FE-SEM micrographs, where CNF with diameter size 20 – 40 nm was formed after 10 cycles of milling. It was also revealed that the obtained CNF possessed appropriate properties as a reinforcement material. The tensile strength and Young’s modulus of poly((R)-3-hydroxybutyrate-co- (R)-3-hydroxyhexanoate (PHBHHx) increased by 19 and 12%, respectively after the reinforcement of 1% CNF. Overall, this study portrays that waste paper could be utilized as a raw material for CNF production, without the need for chemical pretreatment.
The vegetative grafting effect on increasing tomato fruit quality

In Uzbekistan, the vegetative grafting effect on the tomato fruits quality was studied. Table tomato varieties Gulkand, AVE-Maria and Marvarid (cherry tomato) were used as grafts. Each variety was grafted onto its own seedlings, as well as in combinations with four tomato accessions from the World Vegetable Center. The control was not grafted plants. The grafting of varieties depending on the rootstock helped increase the yield by 16-20% and the marketability of fruits by 97-100%. The Gulkand variety, in combination with rootstocks L03708 and CLN2071B, has its average fruit weight increased by 30-35%, AVE-Maria – by 11-18% and Marvarid – by 24-43% above the control plants. The low variability of the dry matter content (V=6.4%) and total sugar (V=9.0%), and the middle variability of the ascorbic acid content were established as well (V=12.5%). In the Gulkand and AVE-Maria varieties, the dry matter content was close to the control level, and in the Marvarid variety it has increased in combinations. Total sugar content has slightly decreased in all combinations of the Gulkand variety. The ascorbic acid has increased in all varieties in combinations. The variability of the chemical composition did not depend on the type of rootstock (Lycopersicon esculentum Mill.) or (ssp. Pimpinellifolium) The nitrate nitrogen in fruits in all varieties and combinations was 1.4–2.3 times lower than the MPC.
An Overview of Signal Processing Methods for Signal Source Localization

1 Abstract —The majority of modern applications require signal processing methods that can provide the expected results, such as signal source’s position in space, based on the time delay between the received signals. The performance of each method varies according to the signal to noise ratio, the sampling frequency, or the type of signal, etc. This paper aims to present and compare several signal processing methods in an effort to determine the optimum solution for the localization of signal sources. Methods such as the Spectrogram, Wavelet Transform, Cross-Correlation or Recurrence Plot Analysis were simulated using Matlab software. The conclusion is that Cross-Correlation is the optimum method in real-time applications, in the case of a high sampling frequency, followed by Recurrence Plot Analysis.
Leading pretreatments for enhancing the degradability of lignocellulosic wastes and the final products

Lignocellulose is the major source for bioenergy (biogas and ethanol) recovery. The first step is enzymatic hydrolysis. Enzymatic hydrolysis is the rate-limiting step due to the complex structure of cellulose, hemicellulose, and lignin. This paper reviewed the effect of current leading pretreatments on the digestibility of lignocellulosic wastes; the pretreatments can be classified as physical, chemical, biological, and physical-chemical methods. The effects of different pretreatments were mainly evaluated by the efficiency of biogas or ethanol production. In addition, some important parameters, such as lignin content, particle size, crystallinity, accessible surface area, and sugar yield were used as indicators of the effects of pretreatments.
Intrakoronare Transplantation Humaner Nabelschnurvenen-Endothelzellen (HUVECs) in das Rattenmyokard: Machbarkeit und Zellschicksal

Publikationen der vergangenen Jahre haben nahegelegt, dass sich Endothelzellen in Kardiomyozyten transdifferenzieren konnen. In der vorliegenden Studie wurde daher am Rattenmodell das Potenzial intrakoronar applizierter humaner Nabelschnurvenen-Endothelzellen (HUVECs) zur in vivo-Transdifferenzierung in Kardiomyozyten untersucht. Zuerst wurde ein minimal-invasives, katheter-basiertes Verfahren zur effektiven intrakoronaren Zellapplikation in Rattenherzen validiert. Durch immunhistochemische Farbungen mit speziesspezifischen Antikorpern konnte nach intrakoronarer Transplantation EGFP-exprimierender HUVECs gezeigt werden, dass HUVECs die myokardiale Endothelbarriere passieren, sich jedoch intramyokardial nicht in Kardiomyozyten transdifferenzieren oder mit diesen fusionieren, sondern programmiertem Zelltod unterliegen. Dass HUVECs auch in vitro keine myozytare Transdifferenzierung eingehen, konnte in Co-Kultur mit neonatalen Kardiomyozyten (neoKMs) verifiziert werden. Weiterfuhrende Experimente bewiesen erstmals die Fahigkeit apoptotischer, EGFP-positiver HUVECs, Nukleinsaure-tragende Apoptotische Korperchen (ABs) zu bilden, welche sowohl in Co-Kultur von HUVECs mit neoKMs als auch bei Co-Inkubation AB-haltiger Suspension mit neoKMs von Kardiomyozyten inkorporiert wurden. Die in beiden Ansatzen nach 6 bzw. 4 Tagen beobachtete EGFP-Expression durch neoKMs lasst sich nur durch AB-vermittelten horizontalen Gen-Transfer von HUVECs in neoKMs plausibel erklaren. Da EGFP-markierte Zellen haufig eingesetzt werden, muss dieser Mechanismus in Versuchen zum Transdifferenzierungs- bzw. Fusionspotenzial von Zellen stets bedacht werden. Daruber hinaus ist die EGFP-Detektion im mikroskopischen Praparat – ohne weitere absichernde Befunde – nicht ausreichend, um das Schicksal von Zellen zu interpretieren.
What Happens to Bad Actors in Organizations? A Review of Actor-Centric Outcomes of Negative Behavior

Negative workplace behavior has received substantial research attention over the past several decades. Although we have learned a lot about the consequences of negative behavior for its victims and third-party observers, a less understood but equally important research question pertains to the consequences for bad actors: How does engaging in negative behavior impact one’s thoughts, feelings, and subsequent behaviors? Moreover, do organizational members experience costs or benefits from engaging in negative acts? We address these questions with an integrative review of empirical findings on various actor-centric consequences of a wide range of negative behaviors. We organize these findings into five dominant theoretical perspectives: affective, psychological-needs, relational, psychological-resources, and cognitive-dissonance perspectives. For each perspective, we provide an overview of the theoretical arguments, summarize findings of relevant studies underlying it, and discuss observed patterns and contradictory findings. By doing so, we provide a very tentative answer to our initial questions, contending that engaging in negative acts is a two-edged sword for actors and its costs seem to slightly prevail over its benefits. Nevertheless, we make this preliminary conclusion based upon an incomplete knowledge base. In order to further our understanding of actor-centric outcomes of negative behavior, we also identify several important research gaps and needed future research directions.

A Focus on Dynamic Modulus: Effects of External and Internal Morphological Features

The present work examines the effects of external and internal morphological features on the dynamic elastic modulus and its measure. It consists of two parts. The first part considers the effect of geometrical features of probes and shows the key role of roughness as source of a systematic error leading to the underestimation of the Young’s modulus. The second one is focused on the effect of porosity. Several models which consider the porosity as an ideal regular microstructure and the relative equations describing the Young’s modulus vs. porosity have been reviewed and critically discussed. The values of the relative modulus Er predicted by different models are similar for materials with low porosity (p < 0.2) and isolated pores whereas they strongly diverge if p > 0.2 and interconnected pores are present. Moreover, such models fail to describe the elastic behavior of materials correctly also with low porosity (p ≈ 0.1) such as sintered steels in the case of pores with a preferred orientation and an irregular shape.
Phytochemical Screening and Larvicidal Evaluation of Phyto-synthesized Silver Nanoparticles using Palmyra Palm Sprout Extract

One of the objectives of nanotechnology is to synthesize effective nanoinsecticides in a bid to reduce the prevalence of the numerous diseases caused by mosquitoes. This synthesis is even more vital in cases where phytochemicals from plants extracts are used as reducing agents. In this study, phytochemical screening of aqueous sprout extract of Palmyra palm (Borassus aethiopum) was performed, in accordance with some established methods and the results confirmed the presence of alkaloids, flavonoids, saponins, coumarins, glycosides, tannins, phenols as well as quinines, however, sterols, steroids and terpenoids were not detected. Subsequently, the sprout extract was used as a reducing agent in the synthesis of silver nanoparticles (AgNPs). Characterization with Fourier transform infrared and Ultraviolet-visible spectrometry was then carried out to confirm the synthesis. In addition, the AgNPs were further analyzed for larvicidal potency against 1st, 2nd 3rd and 4th instars Culex quinquefasciatus mosquito larvae, at interval concentrations of 5, 10, 20, 25 and 50 ppm. The LC50 and LC90 values discovered to be 9.103 ppm and 134.463 ppm with a correlation of 0.815, as well as 10.316 ppm and 118.810 ppm with a correlation of 0.801, for the 1st and 2nd instars, respectively. Meanwhile, the 3rd and 4th instars had LC50 and LC90 values of 17.585 ppm and 179.052 ppm, respectively, with a correlation of 0.807. This study provides a basis for extracting and analyzing the reduction potential of the phytochemicals present in the sprout extract, as well as the application of AgNPs, in controlling mosquito larvae population.
Green governance: understanding the greening of a leading business event from the perspective of value chain governance

Abstract In contribution to limited research on ways to be greener in the events industry, this paper demonstrates the importance of cross-organization coordination in implementing green events. In a case study on China Import and Export Fair, we examined the interplay of stakeholders in the process of greening from the perspective of value chain governance. The results revealed that (1) key stakeholders formed a profit-driven value chain that inhibited the promotion of green booth, (2) the fair used institutional power and bargaining power to engage key stakeholders, and (3) developed a governance model to encourage greening by using multiple instruments of governance (i.e., green booth standards, knowledge transfer, and a green booth competition). In light of those results, this paper expands the scope of literature on green events by offering novel insights into governance along value chains and highlighting their managerial implications for promoting green events.
Examining the adoption of Big data analytics in supply chain management under competitive pressure: evidence from Saudi Arabia

ABSTRACT Grounded in the Technology-Organisation-Environment (TOE) framework, this study identifies the main factors affecting the intention to adopt Big Data Analytics (BDA) in supply chain management (SCM) for firms based in Saudi Arabia. This study focuses on identifying and analysing the role of competitive pressure as a contextual variable that can moderate the effects of these factors on the adoption intention. A survey of 220 IT managers revealed that compatibility, relative advantage, and top management support are positively perceived factors as they foster the firms’ intentions to adopt BDA in SCM. Their effects on intentions were positively moderated by competitive pressure as a contextual variable. However, BDA complexity and organisational readiness were not supported as influencing firms’ intentions to adopt BDA. The statistical analyses also indicated that the effects of complexity and organisational readiness on intentions are not significantly moderated by competitive pressure. This study contributes to the literature by emphasising the interaction between TOE factors, instead of considering them separately. It also offers guidance to managers aiming to adopt and use BDA in SCM.

The Legal Framework on Hate Speech and the Internet
 Good Practices to Prevent and Counter the Spread of Illegal Hate Speech Online

Hate speech includes all forms of expression which spread, incite, promote or justify hatred towards a person or group. The expansion of the Internet has marked an important change in the phenomenon, insofar as content is no longer mediated by editors. Hate speech based on ethnic, racial and religious hatred is recognized as a violation of the human rights set out by the European and international standards. This is not the case for sexist hate speech, although this difference is not justified by the data. The lack of a shared regulatory definition leads to shortcomings in, or even the complete absence of victim protection. Gender equality and freedom of expression are interconnected: enabling hate speech against women and girls to go unpunished limits women’s freedom of information and deprives society of their voices. The balance must be struck by finding the tools for free speech. An overview of such tools is the goal of this contribution.
Emotion Measurement in Tourism Destination Marketing: A Comparative Electroencephalographic and Behavioral Study

It is commonly assumed that TV commercials successfully influence affective tourism destination image by coupling positive emotions to a destination. In this study we record emotional responses to destination pictures before and after viewing a destination TV commercial from participants’ brains using electroencephalography (EEG). A control group of participants watched the same destination pictures, and an unrelated TV commercial. Emotion-related event-related potential (ERP) components, the P2 and LPP, were derived from the EEG. For the participants that watched the destination TV commercial, the P2 and the LPP were larger in response to destination pictures after compared to before having watched the TV commercial. This effect was not observed in the control group. In a behavioral version of the same experiment, we did not observe any effects in the self-report data. It is concluded that ERP methodology is a useful tool to complement the toolbox of tourism marketing researchers.
Can confidence in mathematical afirmationsinfluence negatively in the advance of the discipline? Why? / ¿La confianza en afirmaciones matemáticas puede influir negativamente en el avance de la disciplina? ¿Por qué?

The research focuses on the analysis of confidence and doubt in mathematical statements. Based on the Grounded Theory, and on the analysis of a historical case, that of non-Euclidean geometries, and especially on the figure of Saccheri, the question in this document is answered. It is argued that confidence in the truth of Euclidean geometry had as an effect the attribution of qualities to said geometry and to the problems identified in that work. Also, expectations about the solution to those problems and logical, ontological and epistemological commitments were made explicit. It seems that handling these effects of confidence with biases and exaggerations can be negative for the development of mathematical work.

A novel stability indicating RP-HPLC Method for the estimation of ulipristal - A Selective Progesterone Receptor Modulator

The present research article described the novel HPLC technique that was developed for the estimation of ulipristal in an API and tablet formulation. Symmetry, C18, 250mm x 4.6mm . i.d. , 5 µm Particle size, column with 0.4 ml/min flow rate, was used for the chromatographic separation. Phosphate buffer, pH 4.6 and methanol as a mobile phase (20:80) with a flow rate of 1 mL/min and eluent at 304 nm was monitored for the mobile phase. In compliance with ICH guidelines, the method was validated. Ulipristal was eluted in this technique with a retention time of 1.516 minutes. The limit of detection was 0. 075μg/ml and the limit of quantification was found 0.25 μg/mL. The calibration curve plot was found linear over the concentration ranges 5-150 μg/mL, with the regression coefficient (R2) of 0.990. The % assay of the marketed dosage form was found at 97.40 %, which is within the acceptance level. The present method of ulipristal force degradation study was performed as per the guidelines. The results of the force degradation study show the highest 11.39% degradation in an acidic stressed condition, in comparison to alkaline, peroxide, thermal and photolytic stressed conditions. The experiential evidence of all the study results revealed the suitability of the quantification of ulipristal in API and tablet formulation routinely.
APPLICATION OF STABLE ISOTOPES TO EVALUATE THE INTERACTION BETWEEN SURFACE WATER AND GROUNDWATER IN NORTH EAST OF DIYALA, IRAQ

It had been adopted two reliable techniques which are hydro-chemical and stable isotopes to study the interaction between groundwater and surface water in Wand dam northeastern of Diyala. Eighteen water samples were collected from Wand dam, piezometers, groundwater pumping wells, spring, accumulation basins, and irrigation water during two periods; June and November 2017. The concentrations of cations in Wand dam water order to Ca2+> Na+> Mg2+> K+, SO4> Cl-> HCO3-. The concentrations of cations in the samples collected from groundwater, irrigation water, springs and accumulation basins order to Na> Ca> Mg2+> K+, Ca2+> Na+> Mg2+> K+, Na+> Ca2+> Mg2+> K+ and Ca2+> Na+> Mg2+> K+ respectively and the anions concentrations have order Cl-> SO4> HCO3-, SO4-> Cl-> HCO3, Cl-> SO4> HCO3 and SO4-> Cl-> HCO3- in groundwater, irrigation water, springs and accumulation basins respectively. There are three groups of water types based on isotopic composition; group A which noted in the Wand dam water, the piezometers Nos. 3 and 4, accumulation basin No.7 and irrigation water. Versus standards Group A is enriched by deuterium and oxygen-18, which show the effect of evaporation. Group B is distinguished by isotopic composition enrichment in groundwater as well as piezometer No. 7 than other piezometers due to the difference of the wells depth. Group C shows that the water samples collected from accumulation basin No.1 and springs have enriched stable isotopes. There is a spatial and temporal variation of isotopic contents and hydro-chemical properties of water samples which could be due to different recharge sources, evaporation processes, and origin of the water. Based on concluded information, there is no evidence proving any interconnection between the water of Wand dam and other water resources, except piezometer No. 5 which could be because of the presence of the permeable bed.
Persistence of Human Pathogens in Manure-Amended Australian Soils Used for Production of Leafy Vegetables

Incorporation of manures into soil can add nutrients, improve soil structure and enhance biodiversity, thereby improving the sustainability of vegetable production systems. Unfortunately, manures can also potentially contain human enteric pathogens. To reduce the risk of contamination, Australian guidelines recommend a withholding period of 90 days between manure application and harvest for high-risk products such as leafy salad greens. Our study examined the appropriateness of these guidelines under conditions replicating those on a commercial vegetable farm. Cow manure and poultry litter with/without addition of non-pathogenic strains of Escherichia coli (E. coli), Listeriainnocua and Salmonella sv. sofia were added to sandy and clay loam soils typical of those used to grow vegetables. Bacterial populations were monitored in the soil and on crops of cos lettuce during spring (A), summer (B) and autumn (C) trials, with testing conducted by a commercial laboratory. Significant declines in E. coli occurred within 6 to 16 days in all trials. Modelling indicated that E. coli populations would be at or close to the limit of detection within 50 days for all of the combinations tested. A 2–3 log die-off of Salmonella spp. occurred within three weeks. However, occasional detections continued throughout trial A. As a result, the probability of detection after 50 days fell from 1.0 to 0.1 and 0.02 in trials B and C, respectively, but remained at 0.44 in trial A. Listeria spp. was the most persistent in soil but was not detected on lettuce at commercial maturity. While this study was limited in scope, the results suggest that a 90 day withholding period between application of manure and harvest significantly reduces risk from enteric pathogens under Australian field conditions.
