Trois essais sur la migration internationale

Cette these vise a contribuer a une meilleure comprehension des facteurs qui agissent sur la decision de migrer des individus. Dans le chapitre 1, nous montrons qu’au Portugal, les immigres occupent souvent des postes pour lesquels ils sont surqualifies, et que cette non-adequation entre profils et emplois occupes influence la selection dans la migration. Les phenomenes de surqualification, plus marques chez les individus les plus qualifies, entrainent une selection negative des migrants, tandis qu’une bonne adequation entre profils et emplois conduit a une selection positive.Dans le chapitre 2, nous tirons profit d’une experimentation sur le terrain pour comprendre comment les decisions de migrer illegalement vers l’Europe des jeunes gambiens sont influencees par l’information qu’ils ont sur les risques associes a cette mobilite. Nous montrons d’abord que les participants au jeu surestiment a la fois le risque de perir en route et la probabilite d’obtenir un statut legal en Europe. Nos resultats suggerent par ailleurs que la decision de migrer illegalement est influencee par l’une et l’autre probabilite. Informer les candidats au depart sur les risques reels encourus pourrait ainsi les aider a prendre des decisions en connaissance de cause et contribuerait peut-etre a sauver des vies. Dans le chapitre 3, nous examinons les liens entre structure familiale et migration, en etudiant l’influence du type d’union des meres sur le comportement migratoire de leurs enfants. Nous trouvons que les enfants nes de meres en union polygame sont plus enclins a migrer vers l’etranger. Nous expliquons ce resultat par la rivalite fraternelle qui en decoule.
Apolipoprotein L1 Gene Testing Comes of Age.

The landscape in nephrology changed dramatically in 2010 with the discovery of genetic association between two coding renal-risk variants (RRVs) in the apo L1 gene ( APOL1 ) and CKD (1). The APOL1 G1 and G2 nephropathy-associated variants arose <10,000 years ago and are present almost exclusively in individuals with recent African ancestry, those with similar genetic makeup to populations currently residing in Africa. The frequencies of these variants rapidly increased, likely due to positive selection for protection afforded from Trypanosoma brucei rhodesiense infection, a parasite causing African sleeping sickness. Due to the trans-Atlantic slave trade, approximately 39% of African Americans possess one APOL1 RRV and 13% possess two. In contrast, hemoglobin S ( HbS ) gene variants are also common in African Americans; however, <8% inherit one or two HbS variants. Ancestry-based variation in APOL1 contributes to the excess risk of ESKD in African Americans, more rapid failure of transplanted kidneys from African American deceased donors, and higher rates of nephropathy in African American living-kidney donors (2,3). The kidney disease historically attributed to hypertension in nondiabetic African Americans with low-level proteinuria also proved to be APOL1 associated, with biopsy findings including solidified glomerulosclerosis and thyroidization-type tubular atrophy (4). In addition, the APOL1 spectrum of kidney disease includes FSGS, HIV-associated nephropathy (HIVAN), severe lupus nephritis, and sickle cell nephropathy (5). APOL1 RRVs are associated with nephropathy in individuals with recent African ancestry residing in the United States, Africa, Europe, South America, and the Caribbean. Beyond genetic association, APOL1 RRVs were shown to directly cause kidney disease in a transgenic mouse model (6). Recent studies show that APOL1 kidney risk variants do not associate with cardiovascular disease (7,8). Despite the evidence that APOL1 risk variants lead to kidney disease, the precise pathogenic mechanisms are not known. Data suggest a toxic gain …
Facile synthesis of perovskite CeMnO3 nanofibers as an anode material for high performance lithium-ion batteries

A facile synthesis of perovskite-type CeMnO3 nanofibers as a high performance anode material for lithium-ion batteries was demonstrated. The nanofibers were prepared by the electrospinning technique. The characterization of CeMnO3 nanofibers was carried out by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy. SEM images manifested nanofibers with a diameter of 470 nm having a rough surface with a porous structure. TEM images were consistent with the observations from the SEM images. The electrochemical properties of CeMnO3 perovskite in lithium-ion batteries were investigated. The CeMnO3 anode exhibited a discharge capacity of 2159 mA h g−1 with a coulombic efficiency of 93.79%. In addition, a high cycle stability and a capacity of 276 mA h g−1 at the current density of 1000 mA g−1 can be effectively maintained due to the high Li+ conductivity in the CeMnO3 anode. This study could provide an efficient and potential application of perovskite-type CeMnO3 nanofibers in lithium-ion batteries.
Bismuthene from sonoelectrochemistry as a superior anode for potassium-ion batteries

Bismuth has a great potential as an anode for PIBs, due to its layered structure with a large interlayer spacing, long mean free path, high volumetric capacity (3800 mA h L−1) and environmental friendliness. Bismuthene, a 2D-layered structure, can be exfoliated from bismuth by mechanical or chemical methods. The unique structure of bismuthene is beneficial to the diffusion of potassium, penetration of the electrolyte, and buffering of the volume change along the c-axis, which will boost the anode performance of PIBs. An ultrasonication-assisted electrochemical exfoliation method was proposed in this study to prepare ultra-thin few layered bismuthene nanosheets (FBNs) simply and quickly. The as-prepared FBNs were employed in KIBs as an anode and delivered highly stable capacities of 423, 356, 275 and 227 mA h g−1 at the current densities of 2.5, 5, 10, and 15 A g−1, respectively. There was no obvious decay over 2500 cycles with a capacity of over 200 mA h g−1 at 20 A g−1, realizing excellent rate-capability and long-term cycling stability in KIBs. Furthermore, the mechanism of the excellent electrochemical performances was elucidated via in-depth characterization and theoretical calculations. This work provides a new strategy to prepare scalable ultra-thin nanosheets, which act as a promising candidate for the anode in energy storage systems.
Usability Evaluation and Assessment of Computed Tomography Scan

Usability is a vital characteristic in operating medical machines, especially radiological machines, such as computed tomography (CT) scans and X-rays. The more the body is exposed to it, the greater the negative effect has. If usability is crucial to a specific industry, it is more crucial in the medical health industry due to its tremendous effect on safety and the patient’s health. This study examines the usability of CT scans based on 14 attributes from hospitals across Saudi Arabia. The study revealed that usability consistency, visibility, minimalism, memory, and flexibility have the most usability catastrophic complaints, where the overall catastrophic rate exceeds 20%. Creating a shortcut for frequently used operations is critically important, because it has a fundamental effect in minimizing physical and mental exertion.
Microchannel fabrication and metallurgical characterization on titanium by nanosecond fiber laser micromilling

ABSTRACT Laser micromilling technique is used to manufacture microchannel on metals and nonmetals. Microfeatures ≤100 µm are still challenging for fabrication by common methods. Nanosecond fiber laser micromachining has become more popular owing to its prospective implementation in laser micromilling. Microchannel application relies on its geometric dimension, profile, and surface quality. In this study, an attempt was made to explore the impact of process parameters scanning times, scanning velocity, pulse repetition rate, and assist gas pressure on top kerf width, taper, surface roughness, and metal removal rate in laser micromilling experimentally. Microchannel width varied between 45.5 and 70.9 µm. A regression model has been developed for each response. ANOVA (analysis of variance) has been carried out to remove insignificant parameters. Thermal stress analyzed by surface cracks inside microchannel by Scanning Electrone Microscopy (SEM) images. Higher PRR, lower no. of scans, higher scanning speed and high air pressure found suitable for lesser surface cracks. Redeposition observed at slower scanning velocity and minimum scanning times. Oxidation zone from boundary of channel varies between 37 and 58 µm. Oxide formed on Ti surface which increases oxygen content toward center of channel from 51.08 to 76.22% compared to outside surroundings.
The effects of aqueous extracts of Cuminum cyminum L. and Pimpinella anisum L. seeds on the improvement of irritable bowel syndrome compared with Loperamide in rats

Irritable bowel syndrome (IBS) is a common disorder of the digestive system. In this study, the effects of aqueous extracts of Cuminum (C.) cyminum L. and Pimpinella (P.) anisum L. seeds in improving IBS in rats were studied in comparison with Loperamide, selective drug frequently used for the treatment of IBS in Iran. For induction of IBS, rats were anesthetized 24 hours after fasting, after which 1 ml of acetic acid was injected intrarectally at a point 8 cm from the proximal rectum, the intestine was stimulated and 1 ml of phosphate buffer was injected into the same point to dilute acetic acid. Healing process was studied in five groups: control, false control, positive control, aqueous C. cyminum extract-treated and aqueous P. anisum extract-treated. C. cyminum extract at 300 mg/kg reduced the movements of the gastrointestinal tract significantly, when compared to the control group. To analyze the mean differences between the groups, statistical analysis was performed by the Statistical package for the social sciences (SPSS) using continuous multivariate method. P values of less than 0.05 were regarded as statistically significant. According to the results, the most substantial improvement was observed in aqueous C. cyminum extract-treated group, which allows us to propose its advantage compared to other treatments. Probably one of the reasons for the beneficial effect of these plants on IBS is the presence of antioxidant substances in these plants.
Indoor Fingerprint Localization Algorithm Based on Variable Weight Using Channel State Information

In order to solve the problems of indoor fingerprint localization algorithm based on static weight, such as low positioning accuracy and poor environmental adaptability, a variable weight indoor based on channel state information with Euclidean distance as weight reference is proposed. In the preprocessing stage, the collected CSI amplitude values are first subjected to Butterworth low-pass filtering denoising processing, and then the values of each sampling point are averaged, and the reference point location fingerprint database is established by combining the known coordinates. The weight index α is introduced in the online positioning stage, and the nearest neighbor is found by the KNN algorithm with the CSI eigenvalue reference. Then the weight index β is introduced, and the Euclidean distance is used as the weight reference, and the nearest neighbor is weighted. Get the coordinates of the target position. The experimental results show that the indoor fingerprint localization algorithm proposed by this scheme has higher positioning accuracy and less fluctuation of positioning error than the traditional KNN-based indoor fingerprint localization algorithm.
Screen Media: A Powerful Reinforcement

The use of screen media has significantly increased and several lifestyle consequences have occurred following this change. Screen media exposure is more common among younger age children. Multiple factors may be the reason for this; however, their use is likely reinforced. Parents seek support from screen media devices, which can help calm and occupy their children in a matter of minutes. However, resorting to electronic devices for instant relief is likely to persist due to both negative and positive reinforcement. Reinforcing screen media in this way will make the use of screen devices inextricable for parents and their children. Explaining the issue clearly and coming up with feasible solutions will help minimize the negative health effects of prolonged screen use, the general desirability of screen media devices, and also improve (and increase) healthy screen time habits in children.
Multimodal learning of pheromone locations

Memorizing pheromonal locations is critical for many mammalian species as it involves finding mates and avoiding competitors. In rodents, pheromonal information is perceived by the main and accessory olfactory systems. However, the role of somatosensation in context dependent learning and memorizing of pheromone locations remains unexplored. We addressed this problem by training female mice on a multimodal task to locate pheromones by sampling volatiles emanating from male urine through the orifices of varying dimensions or shapes that are sensed by their vibrissae. In this novel pheromone location assay, female mice’ preference towards male urine scent decayed over time when they were permitted to explore pheromones v/s neutral stimuli, water. On training them for the associations involving olfactory and whisker systems, it was established that they were able to memorize the location of opposite sex pheromones, when tested 15 days later. This memory was not formed either when the somatosensory inputs through whisker pad were blocked or when the pheromonal cues were replaced with that of same sex. The association between olfactory and somatosensory systems were further confirmed by the enhanced expression of the Activity regulated cytoskeleton protein. Further, the activation of main olfactory bulb circuitry by pheromone volatiles did not cause any modulation in learning and memorizing non-pheromonal volatiles. Our study thus provides the evidence for associations formed between different sensory modalities facilitating the long-term memory formation relevant to social and reproductive behaviors.
Morphological and Morphometric Study of Edaravone in Gentamicin-Induced Nephrotoxicity in Sprague Dawley Rats

Background: Gentamicin is an antibiotic that exhibits a broad spectrum of activity against microorganisms. Now a days uses of gentamicin are limited due to it potentially induces nephrotoxicity by selective accumulation of gentamicin in the kidney. Edaravone is a potent anti-oxidant. It strongly scavenges free radicals, protecting the cells against oxidative stress. Due to the contribution of oxidative stress to the pathogenesis of nephrotoxicity, we tested the hypothesis of edaravone in gentamicin-induced nephrotoxicity in rats. Methods: Various parameters including animal body weight, kidney weight, body weight to kidney ratio, serum creatinine level, serum urea level and histopathology were analysed in nephrotoxicity animals (induced with gentamicin 100 mg/kg/body weight i.p .,) with and without edaravone (10 mg/kg/body weight i,p .,). Results: Gentamicin control rats shows that the body weight and kidney weight has been decreased, while kidney weight to body weight ratio, serum creatinine and serum urea were increased significantly while comparing with the normal control rats. Moreover marked renal histopathological abnormalities like glomerulosclerosis, glomerular hypertrophy, tubular cell degeneration and renal arteriolar hyalinization were seen in the gentamicin control rats. Edaravone attenuated the biochemical analyses such as, serum creatinine and serum urea. It also reduced the kidney weight to body weight ratio significantly. Edaravone treated groups showed slightly increase in the body weight and kidney weight but not statistically significant. Renal histopathological abnormalities were reduced in the edaravone treated rats as its compare with gentamicin control rats. Edaravone per se group shows no toxicity to normal rats. Conclusion: Our study suggests that edaravone ameliorated renal structural and functional abnormalities associated with experimental nephrotoxicity. With the biochemical parameters and histopathological studies, we concluded that edaravone reduced the toxicity caused by gentamicin and can be used against nephrotoxicity. Key words: Gentamicin, Edaravone, Nephrotoxicity, Renoprotection

Dual conformable derivative: Variational approach and nonlinear equations

In this letter, we present a variational approach with a recently proposed form of local deformed derivative, the dual conformable derivative, which leads us to obtain a class of nonlinear equations. The ansatz on the solutions can be mathematically inferred by this dual conformable derivative eigenvalue equation and the q-exponential family functions appear naturally. Also, a clear and natural justification for the appearance of the q → 2 - q-symmetry is given. To show the potential of our variational approach with this type of dual deformed derivative, we obtain the porous medium equation and present insight for the solution in terms of the q-Gaussian. Also, a new dual conformable wave equation, which is nonlinear, is proposed and a solution is built up in terms of q-plane waves. A dual conformable harmonic oscillator equation is also obtained and promptly solved by the natural ansatz. Aspects of the nonlinear Schroedinger equation are also contemplated and one shows that it can be obtained without the need of an additional ϕ-field, from a simple Lagrangian density. The solution to the nonlinear Schroedinger is also expressed in terms of the q-exponential family of functions.
Stability analysis of a discrete SIRS epidemic model with vaccination

ABSTRACT A discrete SIRS epidemic model with vaccination and a general infection probability function is investigated in this paper. The basic reproduction number of the model is calculated. It is proven that the disease-free equilibrium is locally asymptotically stable if and globally asymptotically stable for some additional conditions, and the endemic equilibrium is locally asymptotically stable if . Numerical simulations are presented to illustrate the stability results, and the sensitivity analysis of the basic reproduction number shows that the proportionality coefficient of unvaccinated susceptible, the probability that infected individuals do not recover, and the probability of survival have much more effect on .

The role of satisfaction as a mediator on the relationships between usage intention and word of mouth of Islamic bank products and their determinants

Islamic banks have to become customer centric, if they have to remain competitive in the banking system. The banks need to understand factors that influence word of mouth and customer usage intentions towards their products. Studies that has been conducted to investigate customer word of mouth and usage intentions toward Islamic banking products are limited, and therefore this research is conducted to fulfill the gap. Data were collected from 245 respondents using structured questionnaire and were analysed for descriptive statistics using SPSS. Hypotheses testing were conducted through the use of Partial Least Squares (PLS). Findings of the study showed perceived value significantly influenced satisfaction, word of mouth and customer usage intentions toward Islamic Banking products. However, reputation only significantly influenced satisfaction and word of mouth toward Islamic Banking products. In addition, satisfaction was found to significantly mediate the relationships between reputation and word of mouth, and between perceived value and word of mouth. The information from this study is crucial to Islamic bank managers as it will assist them to develop strategies to attract more customers to use Islamic Banking products, without neglecting word of mouth. In the future, more variables should be considered in determining the customer usage intentions towards Islamic banking products.
