Surface Functionalization of Halloysite Nanotubes for Polyamide 6 Composites

Aufgrund ihres hohen Aspektverhältnisses und ihres natürlichen Vorkommens stellen Halloysit-Nanoröhrchen ideale Verstärkungsstoffe für thermoplastische Polymere dar. Zur besseren Anbindung dieser Nanoröhrchen an die Polymermatrix erscheint eine Oberflächenmodifizierung der Füllstoffe sinnvoll, insbesondere um die Duktilität der Komposite zu erhöhen. In dieser Arbeit werden verschiedene Strategien für die Oberflächenmodifizierung von Halloysit vorgestellt. Polyamid 6-Komposite auf Basis des modifizierten Halloysits wurden durch Extrusion hergestellt und hinsichtlich der Verteilung der Nanoröhrchen und der mechanischen Eigenschaften untersucht. Komposite mit Octadecyldimethylchlorsilanmodifiziertem Halloysit wiesen die besten mechanischen Eigenschaften auf.
Human language in the light of evolution

This paper explores a few consequences of the hypothesis that language evolved for the benefit of speakers. This hypothesis, supported by recent Darwinian scenarios of language emergence, explains why speech production organs were dramatically transformed through evolution, while auditory systems remained practically unchanged. It also explains the need for huge vocabularies and for large episodic memory, and it dismisses the possibility of gesturefirst scenarios of language origins.
Zinc Oxide Nanoparticles (ZnONPs) photocatalyst using pulse laser ablation method for antibacterial in water polltude

Pulsed laser ablation method had been successfully performed to produce high-purity zinc oxide nanoparticles. A low-energy Nd:YAG laser beam, of 30 mJ, was bombarding the zinc plate surface followed by ablating the plate to produce zinc oxide nanoparticles (ZnONPs) solution. Synthesis was carried out in aquades medium with a repetition rate variation of 5 Hz, 10 Hz and 15 Hz. Characterization of the ZnONPs was performed by employing XRD, FTIR, SEM-EDX, imageJ software, and UV-Vis spectroscopy. The image of SEM result that ZnONPs have around shape . The characterization results revealed that most of the ZnONPs are small size spherical particles with average diameter decreased from 23.63 nm, 12.13 nm and 5.59 nm as the repetition rate increased. Energy band gap of ZnONPs in range 3.1-3.2 eV verified of ultraviolaet absorbance. ZnONPs is activated by irradiating UV light so that photocatalyst reaction occurred. The testing of the antibacterial activity of ZnONPs using a liquid dilution method with nanoparticle concentrations of 40 ppm, 60 ppm and 80 ppm. The test results showed the percentage of degradation of Escherichia coli bacteria at concentrations of 40 ppm, 60 ppm and 80 ppm respectively at 89.60%, 97.76% and 98, 70%.
Family mealtime against adolescents’ drinking, drug use, and other risk behaviours. Then and now.

During adolescence, the frequency of family meals may play an important role in both counteracting risk behaviours (e.g., drugs and alcohol use, delinquency, etc.) and in promoting healthy life-styles. Objective. The aim of the present review is to chronologically order and discuss evidence supporting or disconfirming family mealtime’s effectiveness against adolescents‘ risk behaviours. Method. The present work integrated two search-strategies: scientific databanks strategies and retrospective research on sources. Inter-rater quality assessment was applied to obtain three clusters of literature; pioneering studies about nutritional habits, last decades’ evidence, and challenges for future research. Results. Effectiveness of family mealtime in preventing adolescents’ risk behaviours and in promoting healthy lifestyles and positive outcomes is discussed. Conclusions. Open theoretical and methodological questions emerged such as the lack of scientific consensus on how to measure the family mealtime frequency or the need to provide qualitative assessments about the family mealtime experience, among others.
Enhancement of wheat distant hybridization germplasm

The related species of Triticinae are important and valuable gene resources for molecular improvement of wheat(Triti-cum aestivum L.). These species have a number of distinct characteristics that common wheat varieties simply do not have.Through distant hybridization and chromosome engineering in the past years,a number of new germplasms,including wheat("Xiaoyan 6")-rye("German white") addition,substitution and translocation lines,have been developed and characterized.The sequential ge-nome in situ hybridization(GISH) and multi-color fluorescence in situ hybridization(FISH),specific molecular markers,combining with disease resistance evaluation and nutrition,quality and yield identification had screened 10 kinds of new wide hybrid germ-plasms,including sterile lines.The screened germplasms were highly resistant to stripe rust,leaf rust and powdery mildew.Some hybrid germplasms were also of high quality,enriched Zn and Fe,high nutrient efficiency and desirable agronomic traits.These traits made the germplasms new and valuable for effective wheat breeding.Also 414 new EST(expressed sequence tag) markers specific to rye genome and 31 new markers specific to rye chromosome arms had been developed.These molecular markers could be used in marker-assisted selection breeding or to rapidly detect corresponding rye chromosomes or chromosome segments introgressed into wheat background.The identification and mapping of new resistant genes derived from wheat relatives were ongoing.Some new advanced lines of wheat-rye and wheat-Agropyron cristatum were being developed for release as new cultivars.
A Behavior-Centric Concept for Engineering Education in New Product Development

Engineering students need to be prepared for future work environments in which transdisciplinary collaboration and innovative behaviour are key to sustainable success. Classical technical skills will not be sufficient to find adequate solutions to complex and dynamic challenges. This work derives a set of ten behavioral aspects that are additionally required for new product developement and innovation. It presents a novel behaviour-centric concept for engineering education that seeks to systematically foster the required behaviour. It is tested in a university course with 41 students.
Explaining holding periods and exit routes of buy-and-build strategies in private equity

This thesis aims to explain the determinants of holding periods of buy-and-build strategies and examines whether buy-and-build strategies have an impact on the route of exit. By using a sample of 150 UK-based buy-and-build cases with exits from 2007 until 2018, this study finds that longer holding periods are explained by the number of add-ons and the execution of industry diversifying add-ons. Evidence is provided that private equity firms with prior buy-and-build experience are likely to face lower holding periods in subsequent buy-and-builds. Comparing the buy-and-build cases to 290 UK-based standalone private equity cases, longer holding periods tend to be related with financial exits. However, controlling for financial performance of the portfolio company lead this result to become insignificant. Although findings indicate that buy-and-builds tend to decrease the likelihood of a public listing relative to a trade sale, the evidence is not found to be robust. Therefore, no conclusive evidence can be provided for the relationship between buy-and-build strategies and the route of exit.
Roles of telomere and telomerase in the process of ginseno- side Rg1 protection against tert-butyl hydroperoxide-induced senescence in WI-38 cells

Aim To investigate the roles of telomere and telom er ase in the process of ginsenoside Rg1 protection against tert-butylhydroperoxid e (t-BHP)-induced senescence in WI-38 cells.Methods Senile W I-38 cells were induced by t-BHP in vitro. Cell ultrastructure, cell cycle assay and β-galactosidase cytochemistry staining were used to evaluate cell s enescence. Terminal restriction fragment (RTF) length and telomerase activity we re detected by southern blotting and PCR-ELISA, respectively.Results t-BHP induced cell senescence with characteristics of shortenned RTF len gth. Pretreatment with Rg1 significantlyattenuated t-BHP-induced senescence in WI-38 cells. Compared with c ells treated with t-BHP alone, Rg1 pretreatment markedly decreased the shorteni ng of RTF length and resulted in telomerase activation.Conclusion Activation of telomerase and prolonging of RTF length might be involved in t he process of ginsenoside Rg1 protection against t-BHP-induced senescence in W I-38 cells.
USING SEMANTICALLY PAIRED IMAGES TO IMPROVE DOMAIN ADAPTATION FOR THE SEMANTIC SEGMENTATION OF AERIAL IMAGES

Abstract. Modern machine learning, especially deep learning, which is used in a variety of applications, requires a lot of labelled data for model training. Having an insufficient amount of training examples leads to models which do not generalize well to new input instances. This is a particular significant problem for tasks involving aerial images: often training data is only available for a limited geographical area and a narrow time window, thus leading to models which perform poorly in different regions, at different times of day, or during different seasons. Domain adaptation can mitigate this issue by using labelled source domain training examples and unlabeled target domain images to train a model which performs well on both domains. Modern adversarial domain adaptation approaches use unpaired data. We propose using pairs of semantically similar images, i.e., whose segmentations are accurate predictions of each other, for improved model performance. In this paper we show that, as an upper limit based on ground truth, using semantically paired aerial images during training almost always increases model performance with an average improvement of 4.2% accuracy and . 036 mean intersection-over-union (mIoU). Using a practical estimate of semantic similarity, we still achieve improvements in more than half of all cases, with average improvements of 2.5% accuracy and . 017 mIoU in those cases.
Responses of seed germination and yield related traits to seed pretreatment and foliar spray of humic and amino acids compounds in carrot (Daucus carota L.).

This investigation was conducted at Research Farm and Plant Physiology Laboratory, Faculty of Agriculture, Damascus University to study the effects of some humic compounds and amino acids on seed germination characteristics and some quantitative traits of carrot (Nantes variety). Five commercial organic fertilizers were used (WAF1, WAF3, P-Humas, Agro and Acto). The results showed that seed treatments in organic solutions reduced germination time, improved germination uniformity and increased seed vigor. Among all fertilizers WAF3 1.5 g/l (T2), consists of amino and organic acids, was significantly superior and recorded maximum germination capacity and germination percentage 62% and 94% respectively, take minimum time for seeds germination 5.2 day, highest homogeneity of seed germination 14.5 seed/day and seed vigor 1.78 g/100 seedling emergence. Field experiment revealed that foliar application of organic fertilizers significantly improved plant growth and roots yield by increasing plant height, plant fresh weight, leaves fresh weight, roots fresh weight and harvest index. Among treatments, Agro 1.5 mL (T4) “45% organic material in the form of amino acids + (Fe, Mn, S, Zn, B, Cu, Mo)” recorded maximum plant height 43.1 cm, plant fresh weight 143 g, roots fresh weight 111 g and harvest index 77.60%.
Design of Human-Emissive Security Alert System for Residential Application

The aim of this project is to design GSM based security system with feedback call capability for residential apartment. To achieve this the pyroelectric infrared radial (PIR) sensor, a transducer which has the ability to convert human body capacitance into electrical signal was used with all other discrete components built around it. The PIR sensor was used as input component which generates input signal used to drive integrated circuit components, which changes output state to energize a relay causing the device to be able to activate a feedback call. The design was successful and is capable of notifying the security personnel in less than ten seconds once an intruder is detected
Root knot nematode infections promoted by agricultural practice modifications in Vietnam and the impacts on rice production

A survey conducted on newly cultivated lowland rice fields by direct seeding method in Hai Duong Province, Viet Nam, in March 2017 revealed high devastation of the field. In these fields, farmers used an annual crop rotation cycle of rice-scallion-rice. Investigations on the devastated fields revealed that the chemical and physical soil properties were appropriate for rice cultivation. On the other hand, observations done on the root systems showed that the dead plants have symptomatic root galls suggesting the presence of plant parasitic nematodes. Sequencing of the internal transcribed spacer (ITS) region of the rDNA genes of the nematodes showed that the root nematodes extracted from the infested fields belonged to Meloidogyne graminicola. The reproductive factor of the isolated M. graminicola population on the IR64 rice variety (Oryza sativa indica) was normal, suggesting that the impact of this plant pest was not due to the emergence of an unusual virulent population. The combination of the three factors (wrong cropping choice for rotation, using rice variety susceptible to M. graminicola and direct seeding) were obviously promoting the nematode infection and its high proliferation in the surveyed fields. Meloidogyne graminicola could parasitize and propagate in scallions of Vietnam. Since this plant is annually cultivated on a paddy field for crop rotation, preventive measures or alternative plant for crop rottion is necessary.

Machine Learning in Compilers: Past, Present and Future

Writing optimising compilers is difficult. The range of programs that may be presented to the compiler is huge and the systems on which they run are complex, heterogeneous, non-deterministic, and constantly changing. The space of possible optimisations is also vast, making it very hard for compiler writers to design heuristics that take all of these considerations into account. As a result, many compiler optimisations are out of date or poorly tuned. Near the turn of the century it was first shown how compilers could be made to automatically search the optimisation space, producing programs far better optimised than previously possible, and without the need for compiler writers to worry about architecture or program specifics. The searches, though, were slow, so in the years that followed, machine learning was developed to learn heuristics from the results of previous searches so that thereafter the search could be avoided and much of the benefit could be gained in a single shot. In this paper we will give a retrospective of machine learning in compiler optimisation from its earliest inception, through some of the works that set themselves apart, to today's deep learning, finishing with our vision of the field's future.
La lezione mancata

sono equazioni differenziali alle derivate parziali lineari del secondo ordine, rispettivamente di tipo iperbolico, parabolico e ellittico [1, 2], che svolgono un ruolo importante nella formulazione e descrizione di molti fenomeni in vari campi della fisica, come per esempio l’acustica, la fluidodinamica, la termodinamica e l’ottica [3, 4]. In questa lezione, tali equazioni non verranno dedotte in quanto l’attenzione sarà focalizzata nella presentazione di un metodo di risoluzione unificato che permetta di evidenziare sia la potenzialità del metodo di separazione delle variabili e dell’uso delle serie di Fourier sia le analogie e differenze tra le soluzioni delle equazioni dell’onda, del calore e di Laplace. Per rendere questa lezione chiara, comprensiva e completa, prima di affrontare la risoluzione delle equazioni dell’onda, del calore e di Laplace, verrà introdotta un’appropriata notazione adimensionale (sezione I) e risolti alcuni integrali (lista di integrali presentata alla fine della lezione) che risulteranno utili nel determinare i coefficienti delle serie di Fourier (sezione III). Il metodo di separazione delle variabili consentirà, isolando la parte spaziale in comune alle tre equazioni, di presentare una risoluzione unificata (sezione II). Vale la pena ricordare che un’equa-
GOAL PROGRAMMING APPROACH FOR CARRYING PEOPLE WITH PHYSICAL DISABILITIES

Most of today's optimization efforts aim to reduce costs, time or the number of resources used. However, optimization efforts should consider other factors as important as these, such as facilitating the lives of the disabled, elderly and pregnant and helping them in their daily lives. In this study, the Nuh Naci Yazgan (NNY) University (Kayseri/Turkey) personnel transport problems were discussed. The NNY University provides a shuttle service to bring employees to school at the start of the work and to leave them at home after work. In order to shorten the collection / distribution time and the total distance travelled, the service vehicle does not leave / pick up all employees in front of their homes. Instead, the employees are picked up / dropped at appropriate locations on an intuitively determined route. Since only the time and cost savings are taken into account when determining the service route, some employees have a long walking distance to the service route. This creates a very important problem, especially for the disabled and pregnant workers. In this study, a new mathematical model is proposed which takes into consideration the physical disadvantages and occupational positions of the employees in order to determine the shortest vehicle route. The results show that the proposed model can significantly reduce walking distances of physically disabled people without compromising the total distance travelled by the vehicle.
Simultaneous Spectrophotometric Quantification of Crystal Violet and Malachite Green in Aqueous Samples: Combination of Multivariate Calibration Method and Solid Phase Extraction Based on Sodium Dodecyl Sulfate (SDS) Grafted Chitosan Nano-composite

A simple solid phase extraction (SPE) based on sodium dodecyl sulfate grafted chitosan nanocomposite was applied for simultaneous spectrophotometric determination of crystal violet (CV) and malachite green (MG) content of water samples. For the data analysis of the overlapped spectra of the two dyes, the partial least square regression (PLSR) has been utilized. The synthesized sorbent was characterized by Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). The results showed the SDS was successfully cross-linked with the chitosan. Various parameters affecting the simultaneous extraction of the analytes, such as pH of sample solution, sample flow rate and the volume and flow rate of eluent were optimized by central composite design and response surface methodology (RSM). Figures of merits consisting of sensitivity, analytical sensitivity, limits of detection (LOD) and limit of quantitation (LOQ) were calculated to 0.89 ng ml -1 , 762.07, 0.06 ng ml -1 and 0.20 ng ml -1 for CV, and 0.15 ng ml -1 , 128.24, 0.17 ng ml -1 and 0.53 ng ml -1 for MG. The calibration curve showed high correlation coefficients of 0.9995 and 0.9993 for CV and MG, respectively. Moreovere, preconcentration factor and extraction recovery of the analytes were computed based on the regression coeffients of PLSR acting as a multivariate net analyte signal filter.
Short Communication: Proportion faunal assemblage of rodents in geoecological districts of Mordovia, Russia

Andrechev A. 2020. Short Communication: Proportion faunal assemblage of rodents in geoecological districts of Mordovia, Russia. Biodiversitas 21: 3961-3968. In one natural area, animals may have different distribution. They inhabit some areas, while they do not exist. Scientists have been working on this issue for a long time. This study reports that the species composition and species distribution varies depending on geoecological districts. Twenty-eight rodent species have been recorded in the territory of Mordovia, Russia. In the region, the largest number of species belongs to coniferous and broad-leaved forests (42.9%). Species widely distributed in several natural areas (28.5%) ranked second place in terms of their representation. They are slightly inferior to the steppe animal species (25%). The taiga fauna is represented by only 3.6% of the total number of registered species. For each geoecological district, the features of the rodent fauna are given, and rare species are identified. The forest-steppe region of Mordovia is compared in rodent fauna with other regions of Russia with different typical faunal assemblages.
Reflections on the Prospects for Sustainable Tourism in Transition Economies: the Case of the Ushanski National Park, Ukraine

In the late 1990s, the Environment Division of the Council of Europe undertook three pilot projects into sustainable tourism in protected areas in transition economies, in Latvia, Romania and Ukraine. The underlying logic of the overall project was clear: that if sustainable tourism could be developed, there could be dual benefits of first, enhanced economic well-being in areas which have experienced severe difficulties in the transition from state controlled to market economies and second, better protection of highly valued nature conservation assets. Some authors (e.g. Gannon 1994), have written optimistically about the scope for tourism in transition economies. This paper presents a more cautious view and explores the circumstances under which a more optimistic outcome might arise.
