While recent studies suggest a correlation between unhealthy dietary patterns, oxidative stress, inflammation, and male infertility, the potential association ultra-processed foods (UPFs) infertility remains underexplored. Therefore, aim of present study was to investigate UPF intake by evaluating sperm quality parameters. The participants (n = 260) current cross-sectional were recruited from an center in Isfahan Province, Iran. Four semen parameters—such as total motility, concentration,...
In this study, reinforcing effect of nanomodified coir fibers with ferric hydroxide, Fe(OH)3, and aluminum Al(OH)3, on shear strength limed marine clay soil was investigated. Accordingly, triaxial compression (TCS) testing carried out to determine the parameters reinforced soil. Also, wetting/drying cycle conducted assess durability samples. The results from experimental investigation show that lime improved through intended modification natural fiber. Moreover, an increase in effective...
This study addresses the use of alkali-activated binder to evaluate feasibility using this promising technique stabilise soils. One well-known agro-wastes, palm oil fuel ash (POFA), was used as a source binder. Also, sodium hydroxide (NaOH) and potassium (KOH) were alkaline activators. The influence four factors including kind activator, binder, curing condition water content soil on strengthening performance evaluated according improvement unconfined compression strength (UCS). At same...
Some microorganisms such as Sporoscarcina pasteurii precipitate calcium carbonate and are suitable for biocementation. This study aimed to investigate the effects of several factors including concentration bacteria, chemical reactants, temperature, pH on precipitation carbonate. The results showed that after 7 14 days curing, compressive strength silty clay soil samples increased steadily from 5 9. It was observed plays an important role in highest (i.e. 92 kPa) when treated with 50 ml...
The feasibility of using palm oil fuel ash (POFA) as a precursor for alkali activation reactions, in combination with glass fibers discrete reinforcement, has been investigated. experimental work was focused on the shear strength (using unconfined compression tests) and tensile indirect tests flexural tests). According to results, it found that peak stress increased post-peak behavior modified from brittle more ductile response depending amount fiber reinforcement alkali-activated mixtures....
This study addresses the feasibility of using palm oil fuel ash (POFA) as a precursor in alkali activation reactions, well mineral wollastonite microfibers discrete reinforcement. The experimental program focused on two main mechanical properties, i.e., shear strength (using unconfined compression tests) and tensile (indirect tests flexural tests). Results indicated that inclusion fiber reinforcement alkali-activated mixtures, regardless their particular activator-precursor combinations,...
The carbonate (CO 3 −2 ) produced by Sporosarcina pasteurii was injected electrokinetically to enhance the mechanical properties of soft clay soils. In this method Ca2+ into anode chamber and moved towards cathode electromigration electroosmotic flow. Then released CO from a blend bacteria urea chamber. ions were under mechanism. CaCO3 precipitated in presence calcium porous medium soil, consequently increased shear strength soil. polarity reversal applied have homogeneous distribution CaCO3.
This paper reports for the first time stabilization of soil using olivine and application novel techniques utilizing alkaline activation carbonation. A rigorous study addressed effect carbon dioxide pressure alkali concentration (10-M sodium hydroxide additions from 5 to 20%) between 7 90 days. Microstructural compositional changes were evaluated microscopic, spectroscopic, diffraction techniques. Results demonstrate advantages in presence NaOH associated increases shear strength up 40% over...
This paper aims to review the electroosmosis in soils. Electroosmosis is movement of a fluid with respect solid wall as result an applied electric potential gradient. The Helmholtz- Smoluchowski model widely describe processes. rate elecro-osmotic flow controlled by coefficient electro-osmotic permeability soil which zeta dependent. Numbers researchers have studied variation These values range from 4.91×10-06 1.57×10-05 cm2s'-1V-1.
The outbreak of the coronavirus disease 2019 (Covid-19) pandemic not only has created a health crisis across world but is also expected to impact negatively global economy and societies at scale that maybe larger than 2008 financial crisis. Simultaneously, it inevitably exerted many negative consequences on geoenvironment which human beings depend. current paper articulates role environmental geotechnics in elucidating mitigating effects pandemic. It belief all authors Covid-19 presents...
In this study, coir fibres were modified with nanoparticles of calcium hydroxide and magnesium via a chemical treatment in order to increase the tensile strength their interaction soil. To evaluate modification its effects, unconfined compressive tests, indirect flexural tests triaxial carried out at 7, 28 90 days curing age on lime-treated soil reinforced unmodified fibres. The obtained results showed that nano-modification enhanced mechanical properties clay due augmented strength, samples...
Abstract In the current study, a novel ecofriendly soil biostabilizer was produced based on microbial-induced calcite precipitation. An aqueous solution of carbonate ions by utilizing Sporoscarcina pasteurii bacteria under laboratory conditions. Natural zeolite then utilized to remove ammonium from in order prevent any harm environment, including vegetation and groundwater resources. It observed that injection calcium chloride followed ammonium-free carbonate-producing increased unconfined...
