Caractérisation de l’activité antioxydante des extraits de Eriobotrya japonica L

The antioxidants play a basic role in the elimination of the toxic reactive oxygen species excess. Thus, the exploitation of natural plant molecules will be very beneficial for the human health. Therefore, we were interested by the evaluation of the anti-oxidant activity of the phenolic compounds extracted from our local medicinal plant, Eriobotrya japonica L, and that by doing two types of manipulations, of course, after getting the different plant leaves extracts. First, we quantified the phenolic compounds amounts (total phenolics, flavonoids, and condensed tannins), in order to make a qualitative and a quantitative assessment. Then, we realized the antioxidant activity assays such as : the DPPH and ABTS radical scavenging activity. Our study was fenced by the fractionation and the characterization of the antioxidant activity of the extract. The experimental results revealed that Eriobotrya japonica L extracts were rich in total phenolic (95.33 ± 6,22 à 179.2 ± 2.66 mg EAG/g for extract), showed moderate levels of flavonoids and they exhibited significant levels of condensed tannins (183.77±1.76 à 12±1.53 mg EC/g for extract) and they exhibited significant levels of flavonoids. As for the antioxidant activities of the plant, the extracts were very good scavengers of radicals DPPH (the IC50 of the leaves organics extract from chloroform (was114,91 μg/ml), and the leaves organics extract from hexane (was129,14 μg/ml). whereas, the ABTS activity very good (12% ± 6,22% à 66,88% ± 1,58%). These observations lead us toward more studies in this field, so that we get more benefits from our local medicinal plants.
Fast surface water quality analysis based on an ultra-sensitive determination of the antidepressant drug duloxetine hydrochloride on a diamond electrode by voltammetry

ABSTRACT Duloxetine hydrochloride (DUL) is an antidepressant drug that is being increasingly consumed and so, it is classified as an emerging pollutant. As it is found at very low concentration in the environment, in this work, we investigated the electrochemical monitoring of surface waters for trace determination of DUL based on the use of cathodically pretreated boron-doped diamond electrode (CP-BDDE) coupled to differential pulse voltammetry. The antidepressant was determined in Britton-Robinson buffer solution at pH 7.0 and the current was linearly dependent to the concentration in the range of 0.030–0.333 µmol L−1 with a limit of detection of 5.87 nmol L−1. The precision, selectivity, and accuracy were evaluated, and the method was applied to the analysis of real lake, river, and tap water with an average recovery of 101%. The CP-BDDE proved to be an excellent electrochemical platform for trace DUL monitoring in surface waters.
On the Dynamics of Variable Mass Systems

This paper accomplishes two things. It presents a derivation of the equations of motion of variable mass systems. The method presented here is based on Kane's formalism, and is complete, efficient, and mathematically rigorous—avoiding heuristics and many other pitfalls of previous attempts at such derivation. The paper also presents a detailed discussion of the meaning and importance of the various terms of the equations of motion, and the circumstances under which each term can be neglected. It is found that certain judiciously simplified versions of the equations of motion are adequate for most studies. The most important forces contributed by mass variability appear to be the thrust vector and the Coriolis force. The jet damping moment and the moment due to inertia variation are the dominant moments due to mass variability. The study ends with specific equations that are recommended for use in the study of the dynamics of variable mass systems. These equations capture all the important features of the motion of variable mass systems, while remaining simple enough to permit tractable analyses of the behaviour of such systems.
Food-caching dynamics and reproductive performance of gray jays (Perisoreus canadensis)

Food-caching dynamics and reproductive performance of gray jays (Perisoreus canadensis) Talia Heather Sechley Advisor: University of Guelph, 2013 D. Ryan Norris The influence of climate on resource availability and the subsequent effects on reproductive performance is one of the most important processes driving the responses of populations to climate change. For food-caching species, warmer temperatures may accelerate cached food decay, leading to food limitation during the breeding season. I investigated the influence of warm temperatures on the preservation of cached food, and explored the effect of an interaction between climate and habitat quality on food availability and breeding condition of female gray jays (Perisoreus canadensis). Food cached at a high-latitude site decayed the least compared to two lower-latitude sites, and decay was exacerbated on deciduous trees compared to coniferous trees. Further, the percentage of conifers on territories positively influenced final pre-laying weights of females, which conferred a higher reproductive output. These results suggest that climate warming may accelerate cached food decay and carry-over to influence female reproductive performance via habitat quality.
Effet Du Niveau Protéique Et Du Traitement Des Graines De Pois D’angole (Cajanus Cajan (L.) Huth, 1893) Sur La Croissance Du Poulet Local (Gallus Gallus Domesticus, Linnaeus 1758) En Côte d’Ivoire

This paper focuses on evaluating the effect of heat treatment of pigeon pea grains as a source of protein and protein level on local chicken growth. To conduct this study, 135 locally grown one-day-old chicks of roughly equal weight were randomized into 9 groups of equal size. Each group was subdivided into five lots of 3 subjects that were housed in a boxing. Then, three types of treatment (roasting, steaming and drying) were applied to the grains. For each type of treatment, three different protein level foods were developed. Each batch of chicks was fed with a given food. The results showed significant interactions between the protein level and the nature of the heat treatment on the different parameters (PTT <α, PNP <α and PTT * NP <α). Food consumption decreased significantly with protein level and was lower for CG and CV foods. The average daily gain and the feed index of batches fed with CG and CV foods were the best. Depending on the protein level, those titrated at 13% achieved the best growth and feed efficiency. Despite a lack of significant effect of the protein level on protein digestibility, there was a slight drop in protein at a dose of 16%. The nature of the treatment, for its part, significantly influenced the digestibility of proteins.
Pedestrian Dead Reckoning Based on Walking Pattern Recognition and Online Magnetic Fingerprint Trajectory Calibration

With the explosive development of pervasive computing and the Internet of Things (IoT), indoor positioning and navigation have attracted immense attention over recent years. Pedestrian dead reckoning (PDR) is a potential autonomous localization technology that obtains position estimation employing built-in sensors. However, most existing PDR methods assume that the smartphone is held horizontally and points to the walking direction. To solve reckoning errors caused by inconsistency of headings between walking heading and pointing of smartphone, we design an accurate and robust PDR method based on walking patterns, which is identified by multihead convolutional neural networks. In addition to adaptively adjust the threshold of step detection and select the most suitable step length model according to the results of walking pattern recognition, a novel heading estimation approach independent of device orientation is proposed. To mitigate accumulative errors, we proposed an online trajectory calibration method based on forward and backward magnetic fingerprint trajectory matching. We conduct extensive and well-designed experiments in typical scenarios, and the experimental results indicate that the 75th percentile localization accuracy of the three scenarios is 1.06, 1.08, and 1.22 m, respectively, using the commercial smartphone embedded sensor without any dedicated infrastructures or training data. Despite the intricate pedestrian locomotion, the proposed PDR method has great potential in pedestrian positioning.
A Comparative Study of Stonehearst Asylum and The System of Dr. Tarr and Prof. Fether—Conflict Between Film and Text, Ethics and Aesthetics

 The System of Dr. Tarr and Prof. Fether , written by American Romantic novelist Edgar Allan Poe, is regarded as a classic of absurd humorous short story. On this basis, director Brad Anderson adapted it into the movie Stonehearst Asylum . There are some differences between the text and film in space-time, characters, plots, themes, and ultimate artistic principles, reflecting the choices between ethics and aesthetics.
Dynamic Behavior of Pile-Supported Structures with Batter Piles according to the Ground Slope through Centrifuge Model Tests

Pile-supported structures incorporating batter piles are commonly used, and can be installed both on the horizontal and inclined ground. Recent studies have considered the positive role of batter piles during earthquakes, highlighting their satisfactory contribution to structural seismic performance. However, in these structures, even though the dynamic system responses can vary greatly depending on the ground slope, few previous studies have evaluated the seismic performance of batter piles relative to the ground slope. Therefore, this study evaluates the seismic performance of pile-supported structures with batter piles, relative to the ground slope using dynamic centrifuge model tests. The acceleration, displacement, moment, and axial force of the system were experimentally derived and reviewed, and the pile moment and axial force (M–N) interaction diagrams of the pile cross-sections were analyzed. The installation of the batter piles resulted in a greater reduction in the system response in the inclined-ground model (acceleration: −48%, displacement: −50%, and moment: −84%) compared to that in the horizontal-ground model (acceleration: −27%, displacement: +650%, and moment: −77%). Overall, batter piles showed better seismic performance in the inclined-ground model than in the horizontal-ground model.
Analysis of Pollution Related Deficiencies Identified through PSC Inspections for the Period 2014–2018

The aim of this paper is to analyze the available data on recorded ship deficiencies during ship inspections which are related to pollution prevention. The purpose of these inspections regulated under the different Port State Control (PSC) regimes’ Memorandum of Understanding (MoUs), is to detect and disable the operation of substandard ships. The data obtained were sorted according to the six Annexes of the International Convention for the Prevention of Pollution from Ships (MARPOL) Convention, and a comparison was made within the scope of each Memorandum of Understanding by each of the Annexes and antifouling system. By using a Chi-Squared test and correlation analysis, MoUs are compared and analyzed. The conclusions thus obtained provide an insight into the most common deficiencies regarding pollution prevention in the world fleet, revealing which standards are most often met and which are trying to achieve a better degree of compliance with the standards envisaged by law.
Comparison of tracer methods and predictive equations for determination of stream-reaeration coefficients on three small streams in Wisconsin. Water-resources investigations (final)

Four modified nonradioactive-tracer methods and 20 predictive equations for determination of stream-reaeration coefficients (K2) in three small Wisconsin streams were compared with the radioactive-tracer method developed by Tsivoglou. Of the four modified-tracer techniques, the propane-area technique, which measures the total weight of propane gas passing stream-sampling stations, yielded the least mean absolute difference of 11.0 percent compared with the radioactive-tracer method. The propane peak concentration, ethylene peak concentration, and ethylene total weight methods gave mean absolute differences of 18, 21, and 26 percent, respectively.
Current status of microalgae to produce Biogas through Pretreatment of lignocellulosic waste in the era of 21-Century

Modern day civilization is dependent on energy generation by fossil fuels. But the major drawback of using fossil fuels is environmental pollution. Microalgae are potential candidate for production of various products of interest, such as proteins, mini food, pigments and triglycerides that can be converted into biofuels. Lignocellulosic feedstocks are the most abundantly available raw material of plants that can serve as a promising feedstock for cultivating bacteria, fungi, yeasts and microalgae to produce biofuels and other value-added products. Owing to the abundant availability of these low/no cost substrates, can be utilized as feedstocks for cultivating microalgae to generate biogas/biodiesel. Likewise, there is much room to exploit defatted algal biomass to be used as animal/fish feed and oil producing/accumulating genes knowledge in future to produce high and good quality biodiesel and biogas.
A comprehensive review on Citrus aurantifolia essential oil: its phytochemistry and pharmacological aspects

Citrus essential oil, commonly, known as lime oil, has been widely reported in traditional system of medicine. Industrially, oil is isolated by mainly by hydrodistillation from fruit and peel of Citrus aurantifolia, family, Rutaceae. Cultivation practice of citrus plants dates back for over 4000 years and are one of most valuable fruit crops in the world. In this review, we aim to summarise the phytochemical and biological properties of citrus oil. The literature was collected from various online resources such as e journals, books and magazines. The citrus essential oil is globally used in food industry to impart citric flavour and odour to cuisines. Llime juice and oil is known to possess multiple biological properties including anti-cancer, antimicrobial, antioxidant, antiulcer, anti-inflammatory, hypolipidemic, antityphoid and hepatoprotective properties. Due to potent antibacterial and antifungal properties, citrus oil is becoming important component of skin care products. The medicinal importance of plant is due to presence of various secondary metabolites, alkaloids, carotenoids, coumarins, essential oils, flavonoids, phenolic acids, and triterpenoids. The citrus oil is rich in aromatic compounds namely, monoterpenes and their derivatives, aldehydes, ketones, esters, alcohols such as limonene (58.4%), β-pinene (15.4%), γ-terpinene (8.5%), citral (4.4%) and others. The bitter taste and aroma of citrus fruit peels is attributed to limonoids. p-caryophyllene constitute 5.7% of all the sesquiterpenes. On the basis of the available information, we conclude that citrus oil possess huge potential to be developed into pharmaceutical products.
Les composés secondaires soufrés des Allium : Rôle dans les systèmes de défense du poireau et actions sur la biologie des insectes

Les vegetaux appartenant au genre Allium et notamment le poireau, Allium porrum, ont la caracteristique de produire des composes secondaires soufres. A l'instar de nombreuses substances issues du metabolisme secondaire des plantes, ces composes soufres semblent etre impliques dans les systemes de defense naturelle des Allium. Les tests de toxicite realises sur differentes especes d'insectes ont revele que les substances volatiles soufrees emises par ces plantes, les thiosulfinates et leurs produits de degradation, les disulfures et notamment le disulfure de dimethyle (DMDS) sont toxiques vis a vis de toutes les especes testees. Le DMDS provoque la mort des insectes par un disfonctionnement mitochondrial via l'inhibition de la cytochrome oxydase conduisant a une forte diminution de la production d'ATP et de ce fait, a une perte de l'influx nerveux. Toutefois, les larves de la teigne du poireau, Acrolepiopsis assectella, lepidoptere specialiste des Allium et notamment du poireau, sont nettement moins sensibles a ces substances soufrees que les autres especes. Cet insecte a developpe des mecanismes adaptatifs specifiques mais pour l'instant inconnus lui conferant cette meilleure tolerance et donc la possibilite de se developper sur sa plante hote riche en substances soufrees. Les composes secondaires soufres produits de facon constitutive par les poireaux agissent tres certainement dans la nature par des phenomenes d'anti-appetence, de repulsion et de toxicite et representent alors un systeme de defense constitutive directe vis a vis des insectes non infeodes a ces plantes. Ce systeme de defense peut probablement expliquer pourquoi si peu d'especes phytophages sont capables de se developper aux depens du poireau. Lorsqu'il est attaque de facon importante par la teigne du poireau, le poireau met en place une reponse se traduisant par une augmentation de la production de composes soufres non volatils pouvant aboutir a une emission plus importante de substances soufrees volatiles. Cette reponse du poireau induite par l'attaque des teignes a des repercussions sur le comportement et les capacites de developpement du lepidoptere specialiste et semble ainsi representer pour la plante un systeme de defense directe induite. Les composes soufres volatils emis par le poireau en ayant un role tres important dans le comportement de recherche de l'hote par Diadromus pulchellus, parasitoide specialiste des chrysalides de teignes du poireau pourraient etre egalement impliques dans un phenomene de defense indirecte de la plante.
Epigenetic alterations as therapeutic targets in Testicular Germ Cell Tumours : current and future application of ‘epidrugs’

ABSTRACT Testicular germ cell tumours (TGCTs) are heterogeneous neoplasms mostly affecting young-adult men. Despite high survival rates, some patients with disseminated disease acquire cisplatin resistance, entailing the need for less toxic therapies. Epigenetic alterations constitute an important feature of TGCTs, which are also implicated in resistance mechanism(s). These alterations might be used as potential targets to design epigenetic drugs. To date, several compounds have been explored and evaluated regarding therapeutic efficacy, making use of pre-clinical studies with in vitro and in vivo models, and some have already been explored in clinical trials. This review summarizes the several epigenetic mechanisms at play in these neoplasms, the current challenges in the field of TGCTs and critically reviews available data on ‘epidrugs’ in those tumours.
Efficient Execution of ATL Model Transformations Using Static Analysis and Parallelism

Although model transformations are considered to be the heart and soul of Model Driven Engineering (MDE), there are still several challenges that need to be addressed to unleash their full potential in industrial settings. Among other shortcomings, their performance and scalability remain unsatisfactory for dealing with large models, making their wide adoption difficult in practice. This paper presents A2L, a compiler for the parallel execution of ATL model transformations, which produces efficient code that can use existing multicore computer architectures, and applies effective optimizations at the transformation level using static analysis. We have evaluated its performance in both sequential and multi-threaded modes obtaining significant speedups with respect to current ATL implementations. In particular, we obtain speedups between 2.32x and 38.28x for the A2L sequential version, and between 2.40x and 245.83x when A2L is executed in parallel, with expected average speedups of 8.59x and 22.42x, respectively.
Black Males, Impulsivity, and Externalizing Behaviors: A Black Criminology Analysis

Abstract In this paper, we explored whether the relationship between externalizing behaviors and impulsivity may have racialized dimensions. To do so, we uniquely constructed an unbalanced panel dataset from the PHDCN-LCS, which allowed us to examine the within-individual relationships between being a Black male, impulsivity, and externalizing behaviors. Based on the tenets of a Black Criminology, we suggested that because of their exposure to racism, Black males may exhibit the greatest volatility—or changes in their level of impulsivity—across time. Additionally, we explored whether the within-individual effect of changes in impulsivity on changes in externalizing behaviors across time may be greater for Black males in comparison to Black females, White females, and White males. The results revealed that Black males exhibited greater changes in their within-individual levels of impulsivity across time and that the within-individual effect of changes in impulsivity on changes in externalizing behaviors was greater for Black males than their counterparts. Our analyses suggest that further testing of the tenets of a Black Criminology is warranted.
Productive and Reproductive Performances of Indigenous Sheep in Ethiopia: A Review

Sheep in Ethiopia is among the major economically important livestock species in the country, playing a significant role to the livelihood of resource-poor farmers and pastoralists. A number of research works were done in the past which evaluate and improve the performance of indigenous sheep in Ethiopia. However, compiled information concerning the production and reproduction potential of indigenous sheep in the country is not available. In this paper, performance of major production and reproduction traits of indigenous sheep is reviewed and discussed. The information presented in this review indicated that, 16 to 126 g/d average daily gain, 7 - 18 kg hot carcass weight and dressing percentage of 34% to 49% (slaughter body weight basis) at 18 - 26 kg slaughter body weight have been recorded for Ethiopian sheep breeds fed various type of basal and supplement diets. These parameters showed variation within a breed and among breeds in various feeding trials and they increased as the level of supplement increases. However, despite sizeable information upon the response of sheep to various types of supplementary feeding, their full growth and other production potential of the majority of sheep breeds of the country are not well studied. Therefore, in future research work, emphasis should be given to explore the genetic potential of various production traits of sheep breeds of the country. Regarding the level of reproduction, 11 to 16 month age at first lambing (for most sheep breeds) and 7 to 10 month lambing intervals have been reported by various authors. The litter size result (1.01 to 1.7 lambs) showed that, there is high capability of Ethiopian sheep to give multiple births. The average pre-weaning mortality rate for most Ethiopian sheep breeds vary from 8% to 56%, which indicated that mortality is a major constraint that affects productivity of sheep in Ethiopia. Generally from the previous results it can be concluded that there is high variability within a breed and among Ethiopian sheep breeds in various production and reproduction traits. This implicates the presence of huge opportunity to improve these traits through improved management and selection.
