Background: Lycopene is a phytochemical exhibiting wide range of health benefits and bioactivities. The present study focuses on lycopene’s in vivo antioxidant properties evaluates the efficiency dietary lycopene supplements alleviating cadmium-induced oxidative stress. Methods: experimental rats were divided randomly into four groups (n=20): untreated control, lycopene-treated, cadmium-exposed cadmium-lycopene groups. Result: Lycopene-accessed revealed improvements both haematological...
It is postulated that alterations in membranous lipids construction, surface characteristics, fluidity, Ca2+ permeability, and cholesterol levels collectively contribute to the process of capacitation induction. The change sperm membrane calcium permeability following main signal for acrosome reaction. response commonly induced vitro using ionophore. study's objectives are determine how ionophore (ionomycin) solvent dimethyl sulfoxide (DMSO) affect motility, hyperactivity, velocity bovine...
Summary Harmonics contamination is an unavoidable phenomenon for ground-force signals generated by a Vibroseis truck. To enhance the quality of seismic data, it preferred to use fundamental mode signal, instead pilot sweep, cross-correlate measured raw data. We present effective harmonics decomposition method separate different orders from signal Our builds mathematical model all in analytical domain, and inverts via solving overdetermined linear equation. synthetic example field data...
Summary We have developed a new picking algorithm based on line detection using conventional edge approach and robust regression method called random sample consensus (RANSAC). Unlike other methods, it uses combination of lines originating from signal attributes first break resulting in excellent continuity between the output picks, even for datasets that low signal-to-noise ratios (SNRs).
Abstract Well control has been one of the most important items in oil and gas production engineering. The wellhead plays a vital role well as it consists many valves, including master valve (MV), crown (CV), wing (WV). MV is lower that directly exposed to pressure. Therefore, it's very ensure valves holding terms functions tests greasing. Passing stuck partial closed position considered tremendous challenge, not only integrity but also for intervention. cannot be opened allow intervention...
Bacterial resistance to conventional antibiotics has created an urgent need develop enhanced alternatives. Nanocomposites combined with promising antibacterial nanomaterials can show improved antimicrobial activity compared that of their components. In this work, green synthesized CuO nanoparticles (NPs) supported on anionic clay a hydrotalcite-like structure such as Zn-Al layered double hydroxide (LDH) nanocomposite were investigated agents. This was using
Quercetin is the most prevalent flavonoid; its bioactivities have a preventive role in helping protect cells against various damaging effects. Complex vitamin E and selenium help enhance immune system maintain brain heart health, as well keep normal cell division. Cadmium hazardous heavy metal that exists naturally, both occupational environmental exposure to cadmium were reported. The present study was undertaken compare efficiency of quercetin combined ameliorate oxidative stress induced...
The liquid whey is a byproduct produced during cheese making. Cadmium highly hazardous heavy metal with cumulative toxic effects. present research work was done to clarify the possible role of proteins in alleviating cadmium-induced oxidative stress. used rats were allotted equally and randomly into three experimental groups; untreated control, cadmium-exposed, cadmium-exposed protein-administered groups. biochemical haematological assays exposed cadmium (group 2) manifested significant...
We have developed a novel first break (FB) picking method based on robust regression called random sample consensus (RANSAC). The proposed defines FB picks from many short-lines RANSAC results the seismic attribute trace and its adjacent traces. Our approach allows us to consider both continuity abrupt signal changes via short-line approach, unlike conventional methods that are only of time-delays or sudden changes. In this abstract, is demonstrated with field data acquired in onshore an...
Summary One of the key advantage multicomponent seafloor seismic acquisition is to suppress receiver side ghost and water-layer multiples by PZ processing. It well known that success processing heavily rely on processing/pre-conditioning vertical geophone component. In this study, we propose a pre-conditioning workflow for applying de-noise process enhance compressional wave signal free from shear energy contamination. The proposed fully automated comprised three steps: 1) Masking filter, 2)...
Abstract This work presents a full waveform sonic (FWS) dataset processing to generate high-resolution images of the near-borehole area. The was acquired in nearly horizontal well over distance 5400 feet. Multiple formation boundaries can be identified on final image and tracked at up 200 feet deep, along wellbore's trajectory. We first present new preprocessing sequence prepare data for imaging. leverages denoising algorithms used conventional surface seismic remove unwanted components...
Surface consistent processing, such as amplitude balancing and deconvolution, suffers from non-uniqueness the solution depends on starting point for an iterative solver. Data volumes have increased rapidly more shots receivers are used in modern surveys; however, data points do not help mitigate non-uniqueness. The commonly L2 norm its siblings show limited success. When source/receiver solutions discontinuities, it is challenging to impose reasonable constraints obtain accurate results. To...
Summary An artificial intelligence (AI) are leading to many positive changes in various fields and have showing the potential improve problems or challenges traditional methods. Many AI researches showed that one of most important things for a successful application is preparing good training data. In this abstract, we described an applications diffraction separation using network. The main focus study was how generate dataset purpose with only synthesized We proposed keeping key features...
