Sodium bicarbonate mouth wash was recently shown to increase patients’ compliance. However, the cost implication of this strategy was never explored. Aim: This study is designed to explore the compounding of sodium bicarbonate 2% mouth wash from sodium bicarbonate powder USP and commercially procured intravenous solution, and to determine the estimated cost implication for patients using this strategy. Materials and Methods: Sodium bicarbonate 2% were compounded using commercially procured sterile intravenous 8.4% solution and powder USP, diluted and dissolved in sterile water for irrigation respectively. The estimated cost savings between the 2 methods were compared to each other as well as to savings from when used in preventing or in adjuvant therapy for chemotherapy induced mucositis. Ethical approval not required by UVA Institutional Review Board. Study conducted according to the International Standards of Good Practice. Result: We came up with a new recipe, sodium bicarbonate 2% mouth wash using commercially procured sterile liquid formulation. Due to shortage, we compounded with sodium bicarbonate powder USP. Using USP 795 regulation, we assigned 14 days beyond use date with refrigeration to these formulations. These formulations resulted in estimated cost savings of $3597.52 and $3686.56 respectively if patients were to be treated for chemotherapy induced mucositis for 21 days. When compared to commercially procured sterile liquid formulation, the use of powder USP, will lead to additional estimated 60 to 66.67% savings for patients. Conclusion: By using sodium bicarbonate powder or solution to compound a 2% mouth wash, we came up with a cheap product that could be used by patients in the moment in the hospital. We were also able to suggest ways that an estimated cost savings for patients undergoing cancer treatment that use this product can be computed.展开更多

Washing is vital for denim and other casual garments for bringing some interesting washed-down effects. Unwashed condition does not exhibit customer’s desired look, but after washing, the same garment becomes prominent in improved appearance, softness, comfort, light and dark shade, and patchy look that creates customer’s absolute satisfaction. Garment washing process increases the appeal with a lucrative outlook brought about by mechanical or chemical treatments in dry or wet conditions. This study gives an indication of different types of washing processes and the change of physical and chemical properties due to application of wet and dry washing processes as an imparting desired effect on garments. The aim of the project is to find out the changes that occur in physical properties of denim when it is subjected to stone enzyme wash on 12-ounce, 10-ounce and 8-ounce denim pants. Three different shades, namely dark shade, medium shade and light wash, were taken into consideration. Different behaviors and properties of the garments were found in the physical properties of the samples.展开更多

At present, most of the coking coal washeries are owned by Public Sector Companies; whereas, most of the non-coking coal washeries are owned by Private Sector. Even after six decades of coal washing practices, there has not been significant development in the coal washing intelligentsia. Indian Coal Washing industry is still dependent on imported equipment, which has been designed to treat coal that is significantly different from Indian coal of drift origin. In this paper, authors have ventured into evolution of Indian Coal Washing Industry （with a focus on coking coal washing sector）, its present condition and future prospect for growth. The paper emphasizes need for developing indigenous solutions to industrial challenges and highlights importance of increased coordination among academia-research institutions and coal industry.展开更多

In this study, nano-sulfonated graphene （SGE） was used as a washing agent to evaluate different processing （washing） parameters for the ectopic leaching removal of polycyclic aromatic hydrocarbons （PAHs） from a coking plant soil. X-ray photoelectron spectroscopy （XPS） and fourier transform infrared spectroscopy （FTIR） were used to analyze the characteristics of the SGE tested. The results showed that SGE had a strong adsorption capacity for PAHs through the role of π-π, H-π, and anion-π interactions. The washing parameters, an SGE concentration of 2000 mg L-1, a liquid/soil （L/S） ratio of 10：1, and 4 cycles of successive washing, were set to arrive to the optimum condition for achieving more than 80% of PAH removal. Under the optimum condition, the PAH removal rate decreased with increasing ring numbers. After one washing cycle at SGE concentration of 2000 mg L-1 and L/S ratio of 10：1, the PAH removal rate of the SCE tested was much higher than that of Tween 80 （TW80） or methyl-β-cyclodextrin （MCD） （P 〈 0.01）. Therefore, SGE is a promising material for the nanoremediation of PAH-contaminated soils.展开更多

However, washwater remained from soil washing process contains discrete particulate particles along with heavy metals as solution phase to be treated separately, as well as this process can produce large amount of sludge that requires further treatment, slow metal precipitation, poor settling, the aggregation of metal precipitates. Electrical treatments including electrocoagulation and electrolysis can be effective in removing these substances from washwater. This paper reviews the theoretical models in applying electrocoagulation and electrolysis to remove heavy metals and discrete particulate particles in washwater by examining and comparing the status of washwater treatment technologies which have been undertaken, mostly in the US and EU for the period 1990-2012.展开更多

Experimental results show that successive washing is a continuation of the aging process of intermittent washing. After a successive washing, the pore types showed no difference with the intermittent washing. During successive washing, the characteristics of the pores in the range of 2-15 nm changed only very little. However, the distributions of the pore radius for pores of 20-50 and 300-1000 nm were obviously influenced. It was shown that the volume of larger pores decreased only to a smaller extent after the successive washing, as compared with that of the intermittent washing, and the pore size was affected by the condition of the successive washing. The roles of physisorbed water, intermicellar liquid, weakly bonded water, as well as the role of stirring, have been discussed.展开更多

Different properties like tensile strength, tear strength, dimensional stability to washing, color fastness to washing, color fastness to water, color fastness to perspiration, color fastness to light, color fastness to rubbing, changes in fabric weight were investigated in context with different washing processes for stretch denim fabric. All tests were carried out according to the ISO (International Organization for Standardization). Enzyme washed fabric illustrated better performance regarding tear strength, tensile strength and dimensional stability;but showed moderate performance in different color fastness properties. But the color fastness to rubbing of heavy enzyme stone wash was excellent. No significant change was observed regarding the grade of color change and color staining for color fastness to wash, color fastness to perspiration and color fastness to light with respect to different types of washing processes like enzyme wash, enzyme stone wash, enzyme stone wash with bleaching and heavy enzyme stone wash with bleaching. The grade for dry rubbing and wet rubbing was comparatively better for enzyme wash rather than other washing processes. The GSM (gram per square meter) of stretch denim fabric also increased accordingly after different kinds of washing process rather than untreated stretch denim fabric. The dimensional stability of stretch denim fabric also altered after going through different washing process. The highest shrinkage was occurred in weft direction for heavy enzyme stone wash with bleaching.展开更多

文摘The coupling of washing with adsorption process can be adopted for the treatment of soils contaminated with heavy metals pollution.However,the complex environment of soil and the competitive behavior of leaching chemicals considerably restrain adsorption capacity of adsorbent material during washing process,which demands a higher resistance of the adsorbents to interference.In this study,we synthesized strongly magnetic,high specific surface area(573.49 m^(2)/g)UiO66 composites(i.e.,UiO66-Fe_(3)O_(4))using hydrothermal process.The UiO66-Fe_(3)O_(4) was applied as an adsorbent during the ethylene diamine tetraacetic acid(EDTA)-assisted washing process of contaminated soil.The incorporation of UiO66-Fe_(3)O_(4)results in rapid heavy metal removal and recovery from the soil under low concentrations of washing agent(0.001 mol/L)with reduced residual heavy metal mobility of soil after remediation.Furthermore,UiO66-Fe_(3)O_(4)can quickly recollect by an external magnet,which offers a simple and inexpensive recovery method for heavy metals from contaminated soil.Overall,UiO66-Fe_(3)O_(4)configuration with EDTA-assisted washing process showed opportunities for heavy metals contaminated sites.

文摘Greenwashing behaviors(GWBs)in green finance products(GFPs)by enterprises seriously hinder the realization of environmental protection goals.However,methods for effectively regulating GWBs in GFPs are unclear.This study constructed a tripartite evolutionary game model to analyze the formation and governance mechanisms of GWBs in GFPs among regulatory authorities,enterprises,and investors.Subsequently,the stability equilibrium strategy and key factors influencing the system equilibrium were discussed.Several interesting conclusions were drawn.First,we demonstrated that an interdependence mechanism exists among three game agents who mutually influence each other.The larger the probability of regulatory authorities choosing active supervision and investors adopting feedback,the more enterprises are willing to carry out green projects.Second,three corresponding governance modes for GWBs were put forward following the developmental stages of GFPs.Among these,the collaboration mode is the most effective in incentivizing enterprises to implement green projects.Third,based on sensitivity simulations,the initial willingness of the tripartite stakeholders,investor feedback cost,investor compensation,the penalty for greenwashing enterprises,and the reputational benefit of enterprises are critical factors that influence evolutionary results.Finally,targeted countermeasures were provided for regulatory authorities to prevent enterprises from engaging in GWBs.
文摘A method of analysis for the simultaneous determination of methylisothiazolinone (MI), methylchloroisothiazolinone (CMI), benzisothiazolinone (BIT) and Bronopol (BNP) in washing-up liquid was established. The method consisted of a gradient HPLC analysis at three different wavelengths. The four compounds could be analyzed with good precision and accuracy.
文摘Day by day, the demand and popularity of denim have increased. With the increase in demand for denim, washing has also increased. When we washed a piece of denim fabric, then its properties also changed. The properties are tensile strength, GSM, color fading, stiffness, abrasion resistance, moisture regain, etc. In this study, we conduct different washing processes on denim fabric such are Stonewash, Caustic wash, Acid wash, Normal wash, Pigment wash, Sandblasting, and Super whitewash. After washing, the properties of denim fabric have been analyzed especially strength. The tear and tensile strength were measured by ISO standard. From the above washing method, Normal & pigment wash showed good strength properties comparing with others.

文摘Coal Washing Exploration in India dates back to 1900s; though, first coking coal washeries in India were installed after independence. At present, most of the coking coal washeries are owned by Public Sector Companies; whereas, most of the non-coking coal washeries are owned by Private Sector. Even after six decades of coal washing practices, there has not been significant development in the coal washing intelligentsia. Indian Coal Washing industry is still dependent on imported equipment, which has been designed to treat coal that is significantly different from Indian coal of drift origin. In this paper, authors have ventured into evolution of Indian Coal Washing Industry （with a focus on coking coal washing sector）, its present condition and future prospect for growth. The paper emphasizes need for developing indigenous solutions to industrial challenges and highlights importance of increased coordination among academia-research institutions and coal industry.

文摘Ex-situ soil washing technology offers advantages such as speed and efficiency of remediation and range of application and has been developed to conform with legal requirements and best management practices in USA and some European countries. In this study, nano-sulfonated graphene （SGE） was used as a washing agent to evaluate different processing （washing） parameters for the ectopic leaching removal of polycyclic aromatic hydrocarbons （PAHs） from a coking plant soil. X-ray photoelectron spectroscopy （XPS） and fourier transform infrared spectroscopy （FTIR） were used to analyze the characteristics of the SGE tested. The results showed that SGE had a strong adsorption capacity for PAHs through the role of π-π, H-π, and anion-π interactions. The washing parameters, an SGE concentration of 2000 mg L-1, a liquid/soil （L/S） ratio of 10：1, and 4 cycles of successive washing, were set to arrive to the optimum condition for achieving more than 80% of PAH removal. Under the optimum condition, the PAH removal rate decreased with increasing ring numbers. After one washing cycle at SGE concentration of 2000 mg L-1 and L/S ratio of 10：1, the PAH removal rate of the SCE tested was much higher than that of Tween 80 （TW80） or methyl-β-cyclodextrin （MCD） （P 〈 0.01）. Therefore, SGE is a promising material for the nanoremediation of PAH-contaminated soils.
文摘Soil washing, ex situ mechanical technique, is one of the few permanent treatment alternatives to remove metal contaminants from soils by employing physical separation based on mineral processing technologies to remove discrete particles or metal-bearing particles and/or chemical extraction based on leaching or dissolving process to extract the metals from the soils into an aqueous solution. However, washwater remained from soil washing process contains discrete particulate particles along with heavy metals as solution phase to be treated separately, as well as this process can produce large amount of sludge that requires further treatment, slow metal precipitation, poor settling, the aggregation of metal precipitates. Electrical treatments including electrocoagulation and electrolysis can be effective in removing these substances from washwater. This paper reviews the theoretical models in applying electrocoagulation and electrolysis to remove heavy metals and discrete particulate particles in washwater by examining and comparing the status of washwater treatment technologies which have been undertaken, mostly in the US and EU for the period 1990-2012.
文摘Simulating the traditional painting art by computer graphics is a challenging and attractive subject. Basing on the experience in the ink wash drawing, in this paper, we expound the artistic characters of ink wash painting and particularly analyze the characteristics of the materials used in the ink wash drawing and the relationships between them. A simulation model is presented and some typical visual effects of the ink wash painting are realized.
文摘The effect of successive washing instead of traditional intermittent washing on the porous structure of pseudoboehmite was investigated by mercury porosimetry, N2 adsorption and thermal analysis, while the stabilities of different types of crystals were investigated by X-ray diffractometer. Experimental results show that successive washing is a continuation of the aging process of intermittent washing. After a successive washing, the pore types showed no difference with the intermittent washing. During successive washing, the characteristics of the pores in the range of 2-15 nm changed only very little. However, the distributions of the pore radius for pores of 20-50 and 300-1000 nm were obviously influenced. It was shown that the volume of larger pores decreased only to a smaller extent after the successive washing, as compared with that of the intermittent washing, and the pore size was affected by the condition of the successive washing. The roles of physisorbed water, intermicellar liquid, weakly bonded water, as well as the role of stirring, have been discussed.

文摘This research work was designed to explore the effect of different washing processes (enzyme wash, enzyme stone wash, enzyme stone wash with bleaching, heavy enzyme stone wash with bleaching) on various properties of stretch denim fabric. Different properties like tensile strength, tear strength, dimensional stability to washing, color fastness to washing, color fastness to water, color fastness to perspiration, color fastness to light, color fastness to rubbing, changes in fabric weight were investigated in context with different washing processes for stretch denim fabric. All tests were carried out according to the ISO (International Organization for Standardization). Enzyme washed fabric illustrated better performance regarding tear strength, tensile strength and dimensional stability;but showed moderate performance in different color fastness properties. But the color fastness to rubbing of heavy enzyme stone wash was excellent. No significant change was observed regarding the grade of color change and color staining for color fastness to wash, color fastness to perspiration and color fastness to light with respect to different types of washing processes like enzyme wash, enzyme stone wash, enzyme stone wash with bleaching and heavy enzyme stone wash with bleaching. The grade for dry rubbing and wet rubbing was comparatively better for enzyme wash rather than other washing processes. The GSM (gram per square meter) of stretch denim fabric also increased accordingly after different kinds of washing process rather than untreated stretch denim fabric. The dimensional stability of stretch denim fabric also altered after going through different washing process. The highest shrinkage was occurred in weft direction for heavy enzyme stone wash with bleaching.
