Test of Weak Efficiency on Casablanca Stock Market, Chaotic Dynamic and Long Memory

This paper aim to investigate the weak form efficiency of the Casablanca Moroccan stock market. After a brief explanation of the efficient market theory developped by Eygene Fama, we have made the whole classical econometric tests used to test the weak form efficiency, this is made by using MASI index that represents the whole stocks in Casablanca stock market. At the end of this study, we have rejected the hypothesis of efficience of Casablanca Stock market, and we have deduced that MASI is caracterised aby a choatic dynamic that we have cvalidated by calculation of Lyapunov exponent, finally and in order to judge the model that represent the MASI we have modeled MASI index using the process ARFIMA (p,dq) and we have deduced that MASI is caracterized by a long memory.
FACIES HETEROGENEITIES AND 3D POROSITY MODELLING IN AN OLIGOCENE (UPPER CHATTIAN) CARBONATE RAMP, SALENTO PENINSULA, SOUTHERN ITALY

Appraisal of the volumes of fluid in a carbonate reservoir will typically require a reliable predictive model. This can be achieved by combining studies of well‐exposed carbonate successions with 3D models in order to obtain reliable quantitative data. In this paper, we present a detailed outcrop study and a 3D porosity model of a well‐exposed Oligocene carbonate ramp (Salento Peninsula, southern Italy) to investigate the nature of small‐scale facies and porosity heterogeneities. Porosity and permeability in the ramp carbonates appear to be controlled by the original mineralogy of skeletal components and by depositional textures. The aims of the study were therefore to identify the factors controlling porosity development in an undeformed carbonate ramp; to model the scale‐dependent heterogeneities characteristic of the facies associations; and finally to produce a 3D model of the porosity distribution.
Formation and evolution of porosity during high temperature creep of a nickel-based single crystal superalloy

A Re-containing single-crystal superalloy was used to research the high temperature low stress creep behavior. Transmission electron microscope, scanning electron microscope and some other research methods are employed. The results and analysis are summarized below: Two mechanisms for the steady creep are found in this experiment. The volume fraction of pores after creep test at 1100°C increased more than 2 times compared with that before test, but the increasing at 1000°C is relatively small, which reveals that temperature has an great influence on the formation of pore during creep; There are two types of pores associated with fracture during the creep process. One is the casting shrinkage located between the interdentritic, which is formed in the solidification of the alloy. Another type of pore is nucleated and growing during the creep deformation.
In Vitro Effect of Aspalatone on Platelet Aggregation and Thromboxane Production in Human Platelet Rich Plasma

In vitro inhibitory effect of aspalatone ((3-(2-methyl-4-pyronyl)]-2-acetyloxybenzoate) on collagen-, ADP-, and epinephrine-induced platelet aggregation in human platelet rich plasma (PRP) was compared with the effects of reference drugs (acetylsalicylic acid, cilostazol and ticlopidine). Aspalatone inhibited time and dose dependently human platelet aggregation induced by collagen; relative potency was in the order of cilostazol>acetylsalicylic acid>aspalatone>ticlopidine. Aspalatone, like acetylsalicylic acid, potently inhibited only the secondary phase of ADP-and epinephrine-induced aggregation. Thromboxane production evoked by collagen in human PRP was inhibited significantly and concentration-dependently by aspalatone and acetylsalicylic acid. These results were in agreement with the earlier studies in which the antiplatelet action of aspalatone was indicated to be due to the inhibition of platelet cyclooxygenase activity (Han et al., Arzneim. Forsch./Drug Res. 44(II), 1122, 1994; Suh and Han, Yakhak Hoeji 39, 565, 1995). In addition, the inhibitory activity of aspalatone on the platelet aggregation appears to be inversely related to the rate of nonspecific deacetylation of the drug in plasma.

A longitudinal study of Pekrun’s control-value theory and the internal/external frame of reference model in predicting academic anxiety

Abstract The present two-wave longitudinal study examined 836 Chinese secondary school students over the course of an academic year to investigate the individual antecedents of academic anxiety in multiple subjects. Hypotheses were based on Pekrun’s control-value theory of achievement emotions and Marsh’s internal/external frame of reference model and tested utilising longitudinal data. Students’ academic self-concept, interest, and anxiety were assessed in Chinese, Mathematics, and English. The results of structural equation modelling indicated that in line with the control-value theory and internal/external frame of reference model, academic self-concept and interest had a negative within-domain effect on anxiety but a positive cross-domain effect on anxiety. Despite stereotypic differences in mean levels, the relations between constructs were gender-invariant. We discuss the theoretical and empirical contributions of the study and make suggestions for future research.
A study on half-shaped printed monopole antenna with short stub for UWB system

: In this paper, the authors propose a small printed monopole antenna corresponding to the frequency band of UWB (Ultra-wideband) system that use a frequency of 3.1 GHz to 10.6 GHz. This antenna has a structure in which a bell-shaped UWB monopole antenna formed on a dielectric substrate (FR-4) has a half shape and a short stub is attached to the antenna. The size of the antenna is 30 × 12 × 1.6 mm 3 . The antenna is designed to be smaller than the conventional one proposed by the author, and can operate in the frequency band of the UWB system. From the simulation result, it is shown that good characteristics can be obtained to UWB application for high speed wireless communication.

Differences in oxidative status explain variation in thermal acclimation capacity between individual mosquitofish (
 Gambusia holbrooki
 )

10 1. Evolutionary theory predicts that the capacity to acclimate should be favoured in variable 11 environments. However, perfect compensation for thermal variation is rare and the 12 capacity for thermal acclimation can vary considerably between individuals within natural 13 populations. This variation may be explained by costs associated with acclimation, but it 14 is not clear what these costs are. 15 2. We tested the hypothesis that oxidative stress is a cost of acclimation that could explain the 16 variation between individuals in acclimation capacity. We acclimated individual 17 mosquitofish (Gambusia holbrooki, n = 416) to 18C and 28C sequentially, and 18 determined swimming performance at each temperature to evaluate their acclimation 19 capacity. Fish were then acclimated to either cold (18C) or warm (28C) conditions, and 20 we increased antioxidant capacities of a subset of fish experimentally by administering N21 acetyl cysteine (NAC). We measured H2O2 production, catalase antioxidant activities, and 22 oxidative damage to proteins and membranes. 23 3. We show that there is significant variation in acclimation capacity between individuals, and 24 that there is a trade-off between acclimation capacity and swimming performance in 25 warm conditions. Mean swimming performance across both acclimation temperatures 26 increased with increasing acclimation capacity, but the increase was small biologically. 27 Hence, greater thermal plasticity (high acclimation capacity) resulted in only minor 28 performance benefits across acclimation conditions. We verified this rather surprising 29 result in replicate populations grown i outdoor mesocosms. 30 4. ROS production, antioxidant activities, and oxidative damage were higher in cold31 acclimated fish, and particularly in those fish with low capacity for acclimation. However, 32 A u th o r M a n u s c ri p t
Geochemical Records of the Provenance and Silicate Weathering/Erosion From the Eastern Arabian Sea and Their Responses to the Indian Summer Monsoon Since the Mid‐Pleistocene

We present a multiproxy record of Sr‐Nd isotopes and major and trace elements for clay‐sized (<2 μm) siliciclastic sediment fractions from the International Ocean Discovery Program Site U1456 in the eastern Arabian Sea to extract reliable chemical indicators not influenced by the grain‐size effect, quantitatively estimate detrital provenance, and constrain silicate weathering/erosion in response to the Indian summer monsoon over orbital timescales. A provenance analysis of fine‐grained siliciclastic sediments indicates a two end‐member mixture from the Indus River (20–90%) and rivers draining the Deccan Traps (10–80%). A prominent increase in terrigenous input from the Indus River occurred at ~0.5 Ma, probably resulting from an intensive erosional event in the Himalayan region. Moreover, αAlK at Site U1456, which is calculated as Al/K ratio of the study sample versus Al/K ratio of the upper continental crust, can be generally used to reflect the chemical weathering intensity in the source regions. During most interglacial and even certain glacial periods, the Indian summer monsoon reinforcement is closely coupled with enhanced continental chemical weathering and physical erosion. Wavelet and spectral analyses of the αAlK record display strong 125‐, 35‐, 29‐, and 23‐kyr periodicities since 1.2 Ma with significant ~100‐kyr cycles established at the end of the Mid‐Pleistocene Transition (~0.7 Ma), suggesting forcing mechanisms linked with both Northern and Southern Hemispheric processes. Significant fluctuations observed in silicate weathering/erosion during ~1.2–0.7 Ma indicate an enhancement of the Indian summer monsoon with increased variability in association with the Mid‐Pleistocene Transition.
L’engagement des cégépiens en contexte de migration pour études : une réciprocité incontournable

Chaque annee, plusieurs jeunes Quebecois quittent leur region pour entamer des etudes collegiales. La migration pour etudes, c’est-a-dire un deplacement a plus de 80 kilometres de son milieu d’origine, touche environ 15 % de la population collegiale (Richard, 2017). Outre la transition entre le secondaire et les etudes superieures, l’integration aux etudes collegiales pose de nombreux defis pour ces jeunes : eloignement, adaptation a un nouveau milieu, nouvelles responsabilites (tâches menageres, repas, budget, etc.) et dynamique relationnelle en mouvance. A partir d’entretiens effectues aupres de migrants pour etudes a propos de leur parcours, de leur motivation, de leurs difficultes et des strategies deployees pour surmonter les defis rencontres, ce texte explore le sens et les formes d’engagement associees a cette experience. Ces differentes manifestations sont decrites a travers trois composantes associees a la notion d’engagement academique : cognitive, affective et sociorelationnelle. L’analyse montre que les manifestations d’engagement de ces cegepiens depassent largement le pari de la reussite scolaire. Migrer pour ses etudes collegiales pousse l’individu a s’engager dans differentes spheres de sa vie : academique, professionnelle et citoyenne. Enfin, cet article ouvre egalement la reflexion sur le caractere reciproque de la notion d’engagement en abordant le role des cegeps dans le processus d’integration de ces jeunes. Mots-cles : etudes collegiales, migration, engagement academique, integration, reciprocite
Elevated Levels of Osmoprotectants Securing Sugarcane (Saccharum officinarum L.) during Salinity Stress

Sugarcane (Saccharum sp.) has great economic importance due to its application in the food industry and is also particularly valuable for its use in the production of ethanol and a less polluting renewable bio fuel (Menossi et al., 2008). Originating in Asia, sugarcane is highly productive in the tropical and sub-tropical areas of the world. However, the adverse environmental conditions affect the growth and development of sugarcane plants (Lisson et al., 2005 and Inman Bamber and Smith, 2005). High salt concentrations decrease the osmotic potential of soil solution creating a water stress in plants and also cause International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 8 Number 12 (2019) Journal homepage: http://www.ijcmas. com
Construction of High School Chemistry Module, Based on Problem-based Learning (PBL) on Salt Hydrolysis Material for Gifted Students

This research aims to develop a Problem-based Learning Module for Hydrolysis Material considering the characteristics, feasibility, and effectiveness to accommodate gifted students. The tests were conducted to material experts, media experts, and students. The model used as the basis for the development of Problem-Based Learning (PBL) chemistry module is the 4-D model (Define, Design, Development and Disseminate). Data analysis techniques are observation and questionnaire. Based on the test, it shows that the Problem-based Learning Module received a good category and is worth it to use. Cognitive learning outcomes of students in the experimental class after using the Problem-Based Learning Module is better than the control class that uses conventional learning. It can be seen from the comparison of the average score of improvement in the learning outcomes of experimental class students who use Problem-Based Learning modules. So, it can be concluded that the learning outcomes using the Problem-Based Learning chemistry learning module are better than conventional learning.
The effects of fetal growth on maternal body weight and visceral organ mass in the grasscutter, Thryonomys swinderianus, Temminck

SUMMARY During pregnancy, maternal metabolism changes to support the gravid uterus and the timing of these changes are a function of both gestational length and fetal number. In order to predict the nutrient requirements throughout pregnancy, it is necessary to know the changes which occur in both the reproductive and maternal tissues. Fifty-seven (57) wild grasscutters were used to investigate the increased nutrient requirement of fetal growth on reproductive and maternal tissues in the grasscutter. The animals were categorized into non-pregnant, early pregnancy (d 1 – 50), mid pregnancy (d 51 – 100), and late pregnancy (> d 100) status. Maternal organ weights were reported as fresh weight (g), scaled to empty body weight (EBW; g/g), and maternal body weight (MBW; g/g). Carcass weight declined with advancing pregnancy (P = 0.029), as were the lungs, small and large intestines whilst the weights of the kidneys, liver and remaining viscera increased. The total internal organ mass, due mainly to the significant increases in the ‘remaining viscera’ mass, which is made up of mainly adipose tissues, also increased with advancing pregnancy. From mid pregnancy to late pregnancy, uterine weight increased by 675.3% (52.33±6.525 v. 353.37±26.580). This suggests that pregnancy imposes a huge metabolic demand on the grasscutter, but the animals appear to mobilize maternal nutrient stores, as well as slow down metabolic rate (as indicated by the increases in the fat component of the remaining viscera mass) to meet requirements of the growing fetus and developing mammary glands.
EFFECT OF THE PINEAL GLAND AND MELATONIN ON DOPAMINE RELEASE FROM PERIFUSED HYPOTHALAMUS OF MATURE FEMALE CARP DURING SPAWNING AND WINTER REGRESSION

Background. Melatonin regulates various physiological and neuroendocrinological processes that occur rhythmically, and stimulates or inhibits endocrine activity of various body glands. This acts on the hypothalamic-pituitary-gonadal axis by synchronizing animals with their reproductive cycles. The proximity of melatonin receptors and dopamine and gonadoliberin production sites has led to a hypothesis that dopamine may be a link between melatonin and hypothalamic LHRH. Melatonin may have an indirect influence on animal reproduction through dopaminergic structures of the hypothalamus, but the mechanism involved remains unknown, also in fish, for this reason, the present experiment was conducted. The aim of the study was to determine the effect of melatonin on dopamine release from hypothalamic cells of mature female carp in vitro. Material and Methods. Hypothalami were perifused with a mineral medium containing melatonin (group 1), in the presence of implanted pineal glands (group 2), and with a pure mineral medium (control). Perifusion was 180 min long and samples of the effluent perifusate were collected at 15-minute intervals. Dopamine concentration in the medium was analysed radioenzymatically. The experiment was carried out in the summer during spawning and in the winter during regression. Results. The results indicate that melatonin inhibits the release of dopamine from hypothalamic cells. This effect was only noticeable in the experiment conducted during the spawning period. Conclusion. The present findings show that melatonin may have a role in the hypothalamic control of hypophyseal activity during the spawning period of carp.
Epidermolysis Bullosa: A Case of Successful Total Hip Arthroplasty

Epidermolysis bullosa (EB) is a rare dermatological disease in which patients suffer from skin fragility and blisters. One of the major complications is the development of skin infections, which may preclude surgical intervention. We present a case of a 49-year-old female with a past medical history of EB, who presented to the emergency department (ED) with right groin pain of one-hour duration after falling on her right side. The patient underwent a successful open reduction and internal fixation for her right hip without complications. Over the course of three months after the procedure, she experienced worsening of the pain accompanied by skin necrosis and total collapse of the femoral head. Subsequent total hip replacement surgery was performed using a cementless (Zimmer, Warsaw, IN) prosthesis and fixated via cannulated screws. To decrease the risk of infection, IV cefazolin was given as a prophylactic antibiotic preoperatively. Vancomycin IV and imipenem/cilastatin IV were given for four days postoperatively. We made sure that our patient is experiencing the least possible pain by giving sufficient analgesics after the surgery. We used morphine, paracetamol, and gabapentin for pain control. For 25 days after the surgery, the patient did not complain of any pain. Upon follow-up, sutures were removed, and no surgical wound infection, rashes, or lacerations were noted. We encourage orthopedic surgeons dealing with patients suffering from dermatological conditions with fragile skin such as EB and decreased level of activity that requires total hip arthroplasty to proceed with the surgical intervention after considering adequate infection control to improve quality of life.
Data-Driven Chemical Reaction Classification, Fingerprinting and Clustering using Attention-Based Neural Networks

Organic reactions are usually assigned to classes grouping reactions with similar reagents and mechanisms. The classification process is a tedious task, requiring first an accurate mapping of the reaction (atom mapping) followed by the identification of the corresponding reaction class template. In this work, we present two transformer-based models that infer reaction classes from the SMILES representation of chemical reactions. Our best model reaches a classification accuracy of 98.2%. We study the incorrect predictions of the models and show that they reveal different biases and mistakes in the underlying data set. Using the embeddings of our classification model, we introduce reaction fingerprints that do not require knowing the reaction center or distinguishing between reactants and reagents. This conversion from chemical reactions to feature vectors enables efficient clustering and similarity search in the reaction space. We compare the reaction clustering for combinations of self-supervised, supervised, and molecular shingle-based reaction representations.
