The Influence of Phonological and Grammatical Awareness on EFL Students' Reading Performance

The purpose of the present research was to assess the influence of phonological and grammatical awareness on reading performance of EFL students at Azad Islamic University of Kerman. Based on such a purpose, a series of linguistic tasks were applied in order to find the relationship between phonological and grammatical awareness and reading performance. 50 EFL students participated in the present study through a qualitative and quantitative survey. Phonological awareness was measured by four tasks while grammatical awareness was measured by two tasks. A semi-structured interview was conducted among EFL students and their in order to obtain their feedback regarding the tests and the role of phonological and grammatical awareness in their reading performance. In addition, in order to measure reading performance, a two stage reading task (reading vocabulary and reading short sentences) was used. The results of the present study revealed that phonological and grammatical awareness had a significant role in reading performance of EFL students of the participants

TRANSFER LEARNING METHOD FOR SLEEP STAGES CLASSIFICATION USING DIFFERENT DOMAIN

Sleep stages classification using the signal analysis includes electroencephalogram (EEG), Electrooculography (EOG), Electromyography (EMG), Photoplethysmogram (PPG), and electrocardiogram (ECG). In this study, the proposed method using transfer learning to sleep stages classification. First, we have used the PPG and ECG signals, because they are less complex. This signal has the least complexity, and in this article we used this signal for transitional learning. n this study, we extracted 52 features from two signals and prepared for the classification stage. This method includes two steps, (a) Train data PPG and Test data ECG, (b) Train data ECG and Test data PPG. Results proved that our method has acceptable reliability for classification. The accuracy of 95.25% and 94.63% has been reached

Role of imaging modalities in evaluation of stroke; towards molecular imaging probes

MRI scanners show a spatial resolution of 250 μm in-plane (small lenticel empirical devices permit for 50 μm isotropic voxels for in vivo evaluation) infinite profundity infiltration along with significant good soft tissue contrast. Extracting any new epitomizing technology to the imaging of children has a number of safety interests that must be aimed. However the lack of ionizing radiation makes MRI particularly suitable for a stroke patient. These treatments must be tailored to the individual biochemical set-up or disease stage of each respective patient with the support of diagnostic data. Equipped with these patient-specific data, a therapy regime is selected, taking into account the different molecular defects for each disease as well as the particular clinical history and condition of a patient. Neuroradiological tools such as CT or MRI have become an indispensable part of the examination and work-up of patients with acute cerebrovascular insults

Oil Produktion Affected by ASP and Gelation Technologies

Проведено аналіз впливу технологій внесення інгібітору корозії ASP і технологій огелювання на рівень нафтовидобутку. Показано, що технології огелювання були розроблені для забезпечення більш ефективного вертикального розгорнення, для затоплення природно тріщинуватих порід-колекторів нафти. Наведено результати аналізу ефективності використання комбінації цих двох технологій, які, на думку автора, могли б розширити застосовність лужного поверхнево-полімерного заводнення.Gelation technologies have been developed to provide more efficient vertical sweep efficiencies for flooding naturally fractured oil reservoirs or more efficient areal sweep efficiency for those with high permeability contrast «thief zones». The field proven alkaline-surfactant-polymer technology economically recovers 15% to 25% OOIP more oil than water flooding from swept pore space of an oil reservoir. However, alkaline-surfactant-polymer technology is not amenable to naturally fractured reservoirs or those with thief zones because much of injected solution bypasses target pore space containing oil. This work investigates whether combining these two technologies could broaden applicability of alkaline-surfactant-polymer flooding into these reservoirs. Aluminum citrate-polyacrylamide, resorcinol-formaldehyde, and the silicate-polyacrylamide gel systems did not produce significant incremental oil in linear core floods. Both flowing and rigid flowing chromium acetatepolyacrylamide gels and the xanthan gum-chromium acetate gel system produced incremental oil with the rigid flowing gel producing the greatest amount. Higher oil recovery could have been due to higher differential pressures across cores. None of the gels tested appeared to alter alkaline-surfactant-polymer solution oil recovery. Total water flood plus chemical flood oil recovery sequence recoveries were all similar

Prevention of diagnostic errors in position of conus medullaris in adult patients

Background: Finding the safe location of spinal cord for cerebrospinal fluid (CSF) during surgical procedures is very important due to its various nature for each patient as well as its potential peripheral nervous system hazards. The aim of this study was to find the relationship between the location of conus medullaris (CM) and gender, age and body mass index (BMI) in order to minimize the potential diagnostic errors. Methods: Magnetic resonance imaging (MRI) with T1-weighted sagittal spin echo sequences of the lumbar spine was studied in 350 patients older than 20 years, whom had been referred for imaging in order to assess the potential causes of low back pain of the lumbar spine, and were referred to Shahid Chamran MRI center in Sanandaj, located in the west of Iran in 2014. The results were compared with international standards to reveal the potential errors. Results: In different age groups, the mean position was variable ranging from T12-L1 intervertebral disc to upper part of L1 middle third, not clinically significant. The inter canal position of the spinal cord was toward dorsal. No significant relationship was found between CM and gender, age as well as BMI. Similar relationship was found for the spinal cord position in spinal column. Conclusion: There is a safe region of 2–4 vertebral bodies and intervertebral spaces during spinal block. It means that the variation of CM position and its end level could be a guidance to realize that why neurological symptoms may vary in different patients

Optimum formulation of asp for injection in oil reservoir

Проведено аналіз оптимального складу інгібіторів корозії ASP для нагнітання у нафтовий пласт. Звертається увага на проблему додавання води в нафтовий резервуар, що є, на думку автора, єдиним методом відновлення тиску в резервуарі.Enhanced Oil Recovery is not a new process and it has been utilized by the Oil and Gas industry for several decades, particularly in the use of water flooding as a secondary recovery measure to ensure maintenance of reservoir pressure.1Adding water to an oil reservoir may seem an odd thing to do- anything added to the reservoir should aid in maintaining reservoir pressure, so why add water, as oil and water do not mix? The problem is that most oil reservoirs are solution gas driven, this means that as the oil is produced the reservoir pressure is reduced and the gas that was held in solution is released and expands. This process drives the oil to the producing wells, however the gas is also free to flow and be produced. Once the gas is produced, the reservoir's energy is lost and reservoir pressure is reduced. If this process is the only method of recovery, it will only yield up to 20% of the reservoirs total volume

Simulating fluid-solid interaction problems using an immersed boundary-SPH method

In this work, the Immersed Boundary Method (IBM) is adapted and implemented in the context of Smoothed Particle Hydrodynamics (SPH) method to study moving solid bodies in an incompressible fluid flow. The proposed computational algorithm is verified by solving a number of benchmark particulate flow problems. The results are also compared with those obtained using the same SPH scheme along with a direct solid boundary imposition technique

Fracture Mechanism of Brazilian Discs with Multiple Parallel Notches Using PFC2D

This study presents crack initiation, propagation and coalescenceat or near pre-existing open cracks in a numericalmodel under Brazilian test. Firstly, Particle Flow Code intwo dimensions (PFC2d) was calibrated with respect to thedata obtained from experimental laboratory tests to ensurethe conformity of the simulated numerical models response.Brazilian discs contain one, two, three, four, and five parallelcentred cracks (45° to the horizontal) under compressiveline loading. Models containing two and three cracks havedifferent joint spacing and joint configuration. In model consistingone flaws, tensile cracks initiated from notch tip andpropagates in direction of compressive loading till coalescewith model edge. By increasing the number of notch, first typeof tensile crack initiated at the tips of outer flaws and coalescedwith model edge. Also second type of tensile cracksinitiates from middle of inner flaws and coalesce with tip ofthe neighbouring flaws. The results show that joint spacingand joint configuration has important effect on the failure patternin model consisting two and three notch. Experimentaland numerical results rendered by other researchers showed agood agreement with the numerical results in the coalescencecharacteristics in cracked model. In addition, crack initiationand coalescence stresses in models were analyzed and comparedwith those in the single-flawed model

Prognosis and diagnosis of the Alzheimer's disease in early stages by new magnetic resonance imaging techniques

A large number of people have dementia all over the world, mainly suffering from Alzheimer's disease. The worldwide prevalence of dementia is expected to increase up to 24 million, and would to double every 20 years through to 2040, resulting in an expensive burden of disease. The overlap between clinical groups and the longitudinal stability of the technique which currently may limit its clinical application in this context. The advent of new specific treatments for dementia will doubtless stimulate further research into the use of in vivo MRS as a clinical and scientific technique. Future technological developments may allow biochemical features of the underlying pathology in neurodegenerative disease
