Adsorption of acetic acid onto activated carbons produced from hazelnut shell, orange peel, and melon seeds

For the adsorption of acetic acid from its aqueous solutions in the various initial concentrations, both manufactured adsorbents and a commercial activated carbon were used as a reference. As 717. 738 m2/g at 500 °C activation temperature and 60% H3PO4 concentration, the highest BET surface area of the activated carbon from hazelnut shells was obtained as 717. 738 m2/g. activated carbons of hazelnut shells and orange peel were found to have higher yields than commercial activated carbon.

Community-Based Cervical Cancer Screening using Visual Inspection with Acetic Acid

Introduction: Cervical cancer is the most common cancer among Nepalese women. Cervical cancer screening plays a vital role in lowering the morbidity and mortality of the disease. We examined the prevalence of cervical cancer precancerous lesions of cervical cancer in Nepal's community-based screening services in this report. All women who underwent cervical cancer screening using acetic acid from June 2017 to December 2018 were included. Results: A total of 7,270 people were tested during the study period, with the prevalence of cervical precancerous lesions among 153 participants. In 25 women, cervical cancer was suspected. Conclusions: Precencerous lesions of cervical cancer are low, but there are some risk factors in Nepalese women of a few districts, which include high prevalence of cervical cancer in the early stages. The national screening guidelines for screening should also include young women with known risk factors.

Identification and characterization of acetic acid bacteria species isolated from various sources in Sri Lanka

Gluconacetobacter spp. , A. pomorum aceti, A. pasteurianus, Gluconacetobacter spp. were all reported as A. pomorum, A. aceti, A. pasteurianus, Gluconacetobacter spp. , A. pomorum, A. aceti, A. pasteurianus, Gluconacetobacter spp. , Those of the isolated strains' acetate tolerance were also poor, as shown by the above results. All strains tested showed over acetate production, whether with 4% or 6% initial ethanol up to 36 pp2033. And at 37 u2103, A. pasteurianus PP21 produced an acetic acid production of 2. 2% with 4% initial ethanol, as shown by A. pasteurianus PP21.

Removal of Cd, Cu, Ni, and Pb from Nanoscale Zero-Valent Iron Amended Soil Using 0.1 M Acetic Acid Solution

The aim of the study was to determine the likelihood of removing heavy metal cations from single-metal spiked soil samples that had been pretreated with nanoscale zero-valent iron particles. The results showed that nZVI reduced the number of metals in the exchangeable form and increased the percentage of these metals found in amorphous iron oxides. The study showed that applying nZVI in soil could be helpful for subsequent removal of heavy metals from soil using a 0. 1 M acetic acid solution.

The effect of combining basil seeds and gum Arabic on the healing process of experimental acetic acid-induced ulcerative colitis in rats

Separate intake of basil and gum arabic can reduce inflammation and oxidative stress, according to previous studies. In the course of experimental colitis in rats, the aim of the study was to determine the effect of treatment with basil seeds mixed with gum arabic on healing, inflammation, and oxidative stress. Rats were treated for the next four days with saline or a mixture of basil seeds plus gum arabic or sulfasalazine rectally for four days following the initiation of colitis. The colon, MDA, MPO, TNF, TNFu03b1, TNF, IL6 and IL17 scores of the colon, MDP, TNF-u03b1, IL6 and IL10 averages, as well as the colitis group, were reduced by basil and gum arabic treatment, lowering SOD, GPx, and IL10 levels as compared to the colitis group. Conclusion: After the induction of colitis, the combination of basil seeds plus gum arabic has antioxidant and anti-inflammatory properties, and it accelerates the colon's recovery in experimental colitis evoked by acetic acid.

Thiamine and Indole-3-Acetic Acid Induced Modulations in Physiological and Biochemical Characteristics of Maize ( Zea mays L.) under Arsenic Stress

Arsenic accumulation in plant tissues is a new threat to crop yield and global food security. Vitamin B1 and Indole-3-acetic acid were present in maize at various As stress concentrations, i. e. , 0, 50 and 100 mg/kg sodium arsenite, and 100 mg/kg sodium arsenite were found in a novel study. Pearl exhibited tolerance against As-stress in comparison to Akbar, despite being different. However, under pressured As-stress, thiamine and IAA treated seeds of maize yielded a dramatic increase in plant growth characteristics, plant water status, enzymatic and non-enzymatic antioxidant activities. Priming treatments of thiamine and IAA in both As-stress tolerance and As-stress tolerance revealed that the role of these in As-stress tolerance has greatly increased. Both maize varieties were observed in improving growth under As-stress of thiamine and IAA treatments, with thiamine + IAA > thiamine > IAA.

Decomposition of Formic Acid and Acetic Acid into Hydrogen Using Graphitic Carbon Nitride Supported Single Metal Catalyst

Both formic acid and acetic acid are known as efficient hydrogen carriers in a blend of generation and storage of hydrogen gas. However, at a higher temperature of 780 °C and 98% FA concentration, Pd with 1 wt%, 3 wt%, and 5 wt% of loading over g-C 3 N 4 has successfully produced the optimum gas of 4. 3 mL, 7. 4 mL, and 4. 5 mL in each reaction, respectively, with 1 wt%, 3 wt%, and 5 mL in each reaction. Pd metal at higher temperatures demonstrated high catalytic performance and was the most active component of a monometallic system in ambient conditions. On the other hand, the catalytic decomposition reaction at a higher percentage of Pd metal increased, resulting in more gas. The results also showed poor catalytic decomposition of Cu and Zn catalysts, owing to the small amount of Cu and Zn metal, but also the presence of high metal oxides and promoteds the formation of a passive layer on the catalyst surface.

Ultrasound, Acetic Acid, and Peracetic Acid as Alternatives Sanitizers to Chlorine Compounds for Fresh-Cut Kale Decontamination

Salmonella enterica Typhimurium's effect was demonstrated by plate counting and scanning electron microscopy. At 35 u00b0C, Ultrasound combined with perspitic acid demonstrated elevated reductions in aerobic mesophiles, molds, and coliforms. With ultrasound and acetic acid at 1000 mg/L and acetic acid at 2000 mg/L, the highest reduction in Salmonella was observed. The cellular morphology of the pathogen changed after combinations of ultrasound and acetic acid at 2000 mg/L and perstic acid.

Integrated Metabolomics and Network Pharmacology to Decipher the Latent Mechanisms of Protopanaxatriol against Acetic Acid-Induced Gastric Ulcer

In this research, we investigated PPT's anti-GU behavior in rats in an acetic acid-induced GU model. PPT's daily doses of PPT significantly reduced the ulcer area and the ET-1, IL-6, EGF, SOD, MDA, and TNF-u03b1 levels in serum were all reduced by PPT in a dose-dependent manner. The results revealed that 16 biomarkers, 3 targets, and 3 metabolomic pathways had been identified as playing a vital role in the treatment of GU with PPT, and that molecular docking was further established.
