Effect of Calcium Chloride, Magnesium Sulfate, and Maleic Acid Spraying on Growth and Yield of Two Potato Varieties (Solanum tuberosum L.)

Two different potato varieties, Riviera and Argana, were used in this study to evaluate their performance under the influence of foliar fertilization (calcium and magnesium) at four concentrations (0%, 0.5%, and 1% calcium chloride, and 0.4% magnesium sulfate) and foliar spraying with malic acid at three concentrations (0, 250, and 500 mg L-1) in the vegetable field of the Department of Horticulture and Landscape Design at the College of Agriculture and Forestry during the spring growing season of 2023. The study was conducted using a complete randomized block design with three replicates. Argana variety showed significant superiority over Riviera in traits such as plant height, leaf area, average tuber weight, and yield per plant, while Riviera variety outperformed Argana significantly in the number of aerial stems. The best yield per plant for Argana variety was obtained with 0.4% magnesium sulfate and 250 mg L-1 malic acid treatment, while the best plant height was achieved in the same variety with 0.4% magnesium sulfate and 500 mg L-1 malic acid treatment. The highest number of stems was observed in Riviera variety with 0% calcium chloride and 500 mg L-1 malic acid treatment, while the lowest was in Argana variety with 0.5% calcium chloride and 250 mg L-1 malic acid treatment. The highest leaf area was found in Riviera variety treated with 0.5% calcium chloride and 0 mg L-1 malic acid, while the lowest was in the control treatment of the same variety. The highest average tuber weight was recorded in Argana variety with 0.5% calcium chloride and 250 mg L-1 malic acid treatment, while the lowest was in Riviera variety with 0% calcium chloride and 250 mg L-1 malic acid treatment

Effects of electrokinetic stabilization combined with addition of calcium ions on soil shear strength characteristics in the hilly granitic region of southern China

Enhancing soil shear strength is of great importance in preventing soil collapse and erosion in the hilly granitic region of southern China. However, limited studies have been conducted on improving soil shear strength in collapsing gullies. Electrokinetic stabilization (EKS) involves applying an electrical current through a soil mass to promote the migration of chemicals from injection points, thereby altering the chemical composition of the treated soil to improve its physical properties. In this study, the effects of calcium chloride (CaCl 2 ) addition and EKS techniques on the soil shear characteristics (shear strength, and its two components: cohesion and internal friction angle) of three different soil layers in collapsing gullies were investigated. The results showed that the EKS techniques significantly increased the migration of calcium ions from the anode to the cathode region of the power supply device used in the soils. Using EKS process alone did not increase or even decrease the soil shear strength, but combining EKS with CaCl 2 injection (Ca-EKS) increased the soil shear strength, and this increase was mainly due to the increasing the soil cohesion. The soil cohesion after Ca-EKS treatment increased on average by 49.84%, 83.11%, and 100.36% compared with the soil without treatments (CK) for the red soil, sandy soil, and detritus, respectively. However, soil amended by sole CaCl 2 addition, Water-EKS or Ca-EKS all can not increase soil internal friction angles compared with the CK. These results demonstrated that the application of Ca-EKS can be applied to improve the soil shear strength and stability of gully walls in hilly granitic regions.

Preparation of Oxidized Pellets from Sulfuric Acid Residue Containing Zinc and Lead by Chlorination Roasting and Its Mechanism of Dezincing and Lead Removal

The utilization of sulfur acid residue is an urgent problem confronting sulfuric acid production enterprises, especially the application of sulfur acid residue (SAR) containing lead and zinc. A method combining chlorination roasting using CaCl2 with pelletizing for processing SAR containing lead and zinc was used in this study, and the effect of calcium chloride on pelletizing performance was studied; in addition, the removal behavior of lead and zinc was also studied by using polarized light microscopy (Zeiss double Axioskop 40A), X ray diffraction, SEM and EDS. The results showed that CaCl2 migrated to the surface of the pellets during drying, and this phenomenon resulted in a lower removal rate of lead and zinc inside the pellets than outside the pellets during the preheating phase. When the roasting temperature was 1220 °C, with an increase in the basicity of pellets, the silicate minerals in the pellets gradually decomposed, the hematite particles were gradually refined, and more lead or zinc minerals were exposed, which further increased the removal rate of lead and zinc in the pellets. Finally, the SAR pellets with Pb and Zn removal rates up to 91.33 and 97.88%, and a compressive strength of 2789 N, could be obtained, which is very beneficial to the sustainable development of sulfuric acid mills.

Effect of Calcium Chloride on Chitosan Behavior in an Acidic Water Mixture for Pharmaceutical and Biomedical Applications

The present article reviews the uses of the biopolymer chitosan (CH) and its derivatives as versatile biomaterials for potential drug delivery systems, as well as for tissue engineering applications, analgesia and treatment of arthritis. CH and its derivatives, as natural antimicrobial agents, can be applied in biomedical, biotechnological, and pharmaceutical applications. Its antimicrobial activity depends on many factors, such as its molecular size, source, associated components, concentration and type of microorganism. In addition, in our research described here, we prepared and characterized the dynamic viscosity and the rheological properties of a biopolymer material based on CH/CaCl2 in solution. The dynamic viscosity and shear stress were measured under the influence of an increasing CH concentration of 1 to 10 g/l and an increasing temperature of 288.15 to 318.15 K.

Effects of calcium chloride on the gelling and digestive characteristics of myofibrillar protein in Litopenaeus vannamei

In this study, the effects of CaCl2 (0, 25, 50, 75, and 100 mM) on the gelling and digestive properties of the myofibrillar protein (MP) in Litopenaeus vannamei were investigated. The results showed that increasing CaCl2 concentration led to changes in the tertiary structure of MP. Specifically, compared with the control group, a 64.31 % increase in surface hydrophobicity and a 45.90 % decrease in the sulfhydryl group were observed after 100 mM CaCl2 treatment. Correspondingly, the water holding capacity and strength of the MP gel increased by 24.46 % and 55.99 %, respectively. These changes were positively correlated with the rheological properties, microstructure pore size, and content of non-flowable water. The mechanical properties of MP gel were improved, and the microstructure became more compact with the increase in CaCl2 concentration. Furthermore, the particle size of the digested MP gels decreased in the presence of CaCl2, which improved the digestion characteristics of MP gels.

CmCML11 interacts with CmCAMTA5 to enhance γ-aminobutyric acid (GABA) accumulation by regulating GABA shunt in fresh-cut cantaloupe

The effect of calcium chloride (CaCl2) treatment on γ-aminobutyric acid (GABA) accumulation in fresh-cut cantaloupe and the involved mechanisms were investigated. The result showed that 1% (w/v) CaCl2 treatment increased GABA content and activities of glutamate decarboxylase (GAD) and succinate semialdehyde dehydrogenase (SSADH), while decreased glutamate (Glu) content and GABA transaminase (GABA-T) activities in fresh-cut cantaloupe. CmCML11 and CmCAMTA5 expressions of CaCl2-treated fruit increased by 187.4% and 165.6% than control fruit in the initial 6 h. Besides, expressions of GABA shunt genes, including CmGAD1, CmGAD2, CmGABA-T and CmSSADH were also up-regulated by CaCl2 treatment during early storage. Moreover, acting as a transcriptional activator, CmCAMTA5 could bind to the CG-box in promoters of CmGAD1, CmGABA-T and CmSSADH and activate their transcription. Furthermore, the interaction between CmCML11 and CmCAMTA5 could enhance the transcriptional activation on GABA shunt genes which were regulated by CmCAMTA5. Collectively, our findings revealed that CaCl2 treatment promoted GABA accumulation in fresh-cut cantaloupe via the combined effect of CmCML11 and CmCAMTA5 in the regulation of expressions of CmGAD1, CmGABA-T, and CmSSADH in GABA shunt.

The optimization of the plant nutrient application is critical in this sytem. ‘Fortuna’ and ‘Festival’ strawberry cultivars were used in the two-story production system using the cocopeat as growing media where the plants were treated with calcium (Ca), Lysophosphatidylethanolamine (LPE), Ca + LPE 15 days before harvest. The first fruits were harvested in the second week of January for ‘Fortuna’ while ‘Festival’ as the first fruits were harvested in the third week of February. Among the treatments, Ca + LPE resulted in favorable results for earliness. While ‘Fortuna’ was found the higher yield than ‘Festival’ for yield per plant or yield per area the highest yield was recovered from LPE treatment for ‘Festival’. The highest acidity was recovered from Ca + LPE treatment for neither of the cultivars. For fruit firmness, Ca treatments increased the fruit firmness. LPE had some effect on color formation when compared to control. The results suggest that Ca and LPE treatments may be used to enhance fruit quality characteristics for early strawberry production.

Sodium Bicarbonate and Calcium Chloride for the Treatment of Hyperkalemia-Induced Cardiac Arrest: A Randomized, Blinded, Placebo-Controlled Animal Study.

Current international guidelines recommend administrating calcium chloride and sodium bicarbonate to patients with hyperkalemia-induced cardiac arrest, despite limited evidence. The aim of this study was to evaluate the efficacy of calcium chloride and sodium bicarbonate on return of spontaneous circulation (ROSC) in a pig model of hyperkalemia-induced cardiac arrest. A randomized, blinded, placebo-controlled experimental pig study. Hyperkalemia was induced by continuous infusion of potassium chloride over 45 minutes followed by a bolus. After a no flow period of 7 minutes, pigs first received 2 minutes of basic cardiopulmonary resuscitation and subsequently advanced life support. The first intervention dose was administered after the fifth rhythm analysis, followed by a defibrillation attempt at the sixth rhythm analysis. A second dose of the intervention was administered after the seventh rhythm analysis if ROSC was not achieved. In case of successful resuscitation, pigs received intensive care for 1 hour before termination of the study. University hospital laboratory. Fifty-four female Landrace/Yorkshire/Duroc pigs (38-42 kg). The study used a 2 × 2 factorial design, with calcium chloride (0.1 mmol/kg) and sodium bicarbonate (1 mmol/kg) as the interventions. Fifty-two pigs were included in the study. Sodium bicarbonate significantly increased the number of animals achieving ROSC (24/26 [92%] vs. 13/26 [50%]; odds ratio [OR], 12.0; 95% CI, 2.3-61.5; p = 0.003) and reduced time to ROSC (hazard ratio [HR] 3.6; 95% CI, 1.8-7.5; p < 0.001). There was no effect of calcium chloride on the number of animals achieving ROSC (19/26 [73%] vs. 18/26 [69%]; OR, 1.2; 95% CI, 0.4-4.0; p = 0.76) or time to ROSC (HR, 1.5; 95% CI, 0.8-2.9; p = 0.23). Administration of sodium bicarbonate significantly increased the number of animals achieving ROSC and decreased time to ROSC. There was no effect of calcium chloride on the number of animals achieving ROSC or time to ROSC.

Methylcellulose as a non-bonding gelling agent for calcium chloride methanol fuel gels

Carbohydrate-based fuel gels find diverse applications across industries ranging from renewable energy and transportation to military and emergency preparedness. This study investigates the thermal properties, gel characteristics, combustion performance, micro-, and nano-scale structure of methylcellulose (MC) in methanol and the effect of calcium chloride (CaCl2) addition. The results show that MC exhibits viscoelastic phase separation due to the lower critical solution temperature, resulting in gelation at the 22 wt%. Thermogravimetric analysis reveals good thermal stability of MC in methanol, with a single decomposition stage. Adding CaCl2 modifies rheological behavior and enhances the thermal properties of the MC/methanol gel, with improved combustion and ignition performance due to the formation of CaCl2-methanolates. Small-angle X-ray scattering analysis indicates changes in nanoscale aggregates, correlation length, and fractal dimension with increasing CaCl2 content. This study provides valuable insights into the properties of MC-based fuel gels and their potential applications.

Combined settlement and clogging in drainage sand layer for suspended solids, colloids and inorganic salts

Blockage of leachate drainage facilities is a common engineering problem in landfill operation. The key factors that cause blockage of drainage facilities in landfill leachate are the deposition of suspended solids (SS) with colloids and the precipitation of inorganic salts. To determine the combined sedimentation law of SS, colloids and inorganic salts, a combined sedimentation test of suspended solids, colloids and inorganic salts was conducted. To further clarify the resulting clogging characteristics of the water-conducting sand layers, a sand column blocking test were conducted, and mineral composition and grain characteristics of sediments were determined. The experimental results shown that the colloids (silver iodide) and inorganic salts (calcium chloride or aluminum sulfate) increased the sedimentation rate of SS by 8 to18 times. Among them, the effect of AgI colloid was the most significant, followed by effect of calcium chloride, while effect of aluminum sulfate was the weakest. Compared with sand column clogging caused by SS, this combined migration shortened the sand column clogging time by more than half and reduced hydraulic conductivity by nearly two to three orders of magnitude. This study contributes to the accurate assessment of the service performance of landfill leachate drainage systems.

Изучение процессов образования гидрата природного газа в пористой среде из смеси растворов полимеров с нефтью

The article presents the results of studies of equilibrium conditions and kinetic characteristics of the processes of formation of natural gas hydrate in systems of porous medium - water - polymer - calcium chloride - oil under static conditions. It has been established that, formation of methane and natural gas hydrates mixture occurs in the systems under study. The presence of oil in the reaction system does not affect the equilibrium conditions of the gas hydrates formation within the error but reduces the hydrate formation rateand water-to hydrate convertion. The presence of the CaCl2 salt in the system shifts the equilibrium conditions of hydrate formationto the region of low temperatures. The effect of calcium chloride on the kinetics in a system without polymers has an extreme dependenceand makes it possible to double the gas uptake rate at 50 g/L. The addition of polymers (polyacrylamide, sodium carboxymethyl cellulose, or polyethylene glycol) to the system suppresses the salt effect. The data obtained can be useful in the developmentof reagents for polymer flooding of an oil reservoir during oil production under conditions of gas hydrate stability.

An Experimental Investigation on the Effect of Calcium Chloride As Dust Suppressant on the Strength of Unpaved Road

The quality of the gravel used in road construction has a profound positive impact on roadservice life. The potential use of calcium chloride as a dust control agent and material for stabilizing the base of unpaved roads has been researched.However, the quality of the gravel may be impacted if calcium chloride isintroduced as a dust suppressant into it.The main aim of this researchis to examine the increase in strength of soil specimens treated with calcium chloride and to evaluate how different proportions of calcium chloride as a dust suppressant and base stabilizer affect the California Bearing Ratio value of the soil samples. Mixtures of natural gravel and gravel with varying amounts of calcium chloride were analyzed for their Atterberg limits, grading, maximum dry density, CBR properties, and optimum moisture content.The changes in the characteristics of the gravel -calcium chloride mixtures were analyzed. It was found that the particle size distribution and Atterberg limits remained largely unchanged. However, the optimum moisture content (OMC) decreased from 9.2% to 7.6%, 7.4%, and 7.2% withcalcium chlorideaddedat percentages of2 percent, 3 percent,and4 percent per volumeof dry soil, respectively.Observation of the mixture revealed an increase in the maximum dry density (MDD) as the ratios of calcium chloride were altered.The maximum dry density significantlyincreasedfrom 2.15 Mg/m3to 2.31 Mg/m3, 2.35Mg/m3, and 2.36Mg/m3, respectively. Along with this, the California Bearing Ratio (CBR) demonstrated an improvement of 25% to 29%, 32%, and 36% at 95% compaction with an increase in the ratios of calcium chloride.The increase in dry density can be explained by the improved bonding between particles and the reduction of air voids. This increase in dry density, in turn, positively influences the California Bearing Ratio by transforming soil structure from a dispersed state to a flocculated state.It can be inferred from the results that calcium chloride has the potential to function as a stabilizer for unpaved roads.The findings of this study are expected to reduced life cycle costs for unpaved roads, provide insights for the best approach to materials analysis for unpaved roads, and contribute to environmental benefits by minimizingdust emissions into the atmosphere and reducing the release of chemicals into nature.

The effect of seed priming on the germination properties of Aruncus dioicus

The effects of calcium chloride (CaCl2) and polyethylene glycol (PEG) seed priming on the germination properties of Aruncus dioicus (A. dioicus), an important wild vegetable obtained from forests in Korea, were investigated. The examined factors consisted of three priming concentrations and durations. Our results clearly showed that the germination properties of A. dioicus were affected by the priming conditions. Generally, seed priming with PEG resulted in a higher germination percentage, energy, rate, and time to achieve 50% germination (T50) compared to control and seed priming with CaCl2. Among the experimental conditions used for this study, pre-treatment with PEG at –1.03 MPa for 24 hours resulted in the highest germination percentage, which was 1.9 - fold higher than that of the control. Significantly higher germination energy and lower T50 values were also observed compared to those of the control. These results suggest that specific PEG priming conditions can be successfully used to improve the germination properties of A. dioicus.

Effects of the Incorporation of Calcium Chloride on the Physical and Oxidative Stability of Filled Hydrogel Particles.

In this study, the effects of calcium chloride (CaCl2) addition on the physical and oxidative stabilities of filled hydrogel were investigated. The results revealed that CaCl2 significantly enhanced the particle size, interfacial layer thickness, apparent viscosity, and viscoelastic behavior of filled hydrogels and decreased their light and whiteness values (p < 0.05). This phenomenon was mainly attributed to the strong binding ability between Ca2+ and protein/pectin mixtures, which were present in the interfacial area or aqueous phase, as verified by cryo-scanning electron microscopy results. Moreover, lower levels of CaCl2 (2 or 4 mM) significantly enhanced the oxidative stability of filled hydrogels (p < 0.05), particularly at a concentration of 4 mM. However, a higher level of CaCl2 (6 or 8 mM) resulted in an electrostatic shielding effect, which resulted in the aggregation of multiple droplets and the flocculation of the filled hydrogels, which negatively affected the oxidative stability of filled hydrogels. The findings of this study indicated that appropriate Ca2+ levels (4 mM) improved the physical and oxidative stability of filled hydrogel, and this finding may provide useful insights for the development of effective delivery systems for specific applications.

Effect of calcium chloride and 1-methylcyclopropene combined treatment on pectin degradation and textural changes of Eureka lemon during postharvest storage

During post-harvest storage, the cell wall properties are closely associated with the physical, chemical, and biological properties of the fruit. The degradation of pectin in the cell walls and middle lamella is critical to these properties. The effects of calcium chloride (CaCl₂) and 1-methylcyclopropene (1-MCP) combined treatment on the pectin degradation, texture, and peel color of Eureka lemon were investigated during post-harvest storage. The in-situ light microscope analysis, rapid method, and FTIR test were used to investigate the spatial distribution, the pectin content, and its degradation. The results showed a reduction in pectin degradation, by 42 d the CaCl₂ and 1-MCP combined treated fruits presented a 36.7% pectin content loss which was lower than the control which was 48.3%. The treated fruits significantly exhibited enhanced textural properties, delayed weight loss, higher total acids, and improvement of other physicochemical properties in comparison to the control. The treatment deaccelerated the fruit peel color change from green to yellow and also had a better visual appearance on the final day. Overall, the results suggest that the control treatment for pectin degradation can reduce the fruit texture decline and peel color change and maintain a good visual appearance. The influence of pectin degradation on the texture and physicochemical properties of lemon provides a theoretical basis for fruit storage optimization, quality control, and shelf-life extension.
