Background: Improving Water, Sanitation and Hygiene in health care settings is a critical prerequisite for achieving national health goals and Sustainable Development Goals (SDGs). The World Health Organization (WHO) has set a target for each United Nations member state to reach by 2030. Each member state is required to reach by 2022, 2025 and 2030 at least 60%, 80% and 100%, respectively of basic level of service of the five elements which are water, sanitation, hygiene, waste management and environmental cleaning. Methods: This study aimed to evaluate and document the current state of basic water, sanitation, and hygiene services in all lower-level health care facilities in the Dar es Salaam region of Tanzania as of July 2022. A cross-sectional study was conducted in 99 public dispensaries in the Dar es Salaam region’s five councils: Ubungo, Kigamboni, Kinondoni and Temeke Municipalities, and Ilala City. The interviewee form and observational checklists were both digitalized using the Kobo tool software. The respondents were health care facility in-charges or nurse in-charges. Data were downloaded, validated, and imported to Stata version 15 for analysis. Results: The basic WASH level per JMP is far below the target in 2022. Each member state by 2022 is required to reach at least 60% of the basic level of service of each element. We found a low coverage of basic WASH in the 99 dispensaries included in this study. The basic WASH coverage was met in only 10 (10.1%) of the dispensaries, while the remaining 89 (89.9%) dispensaries fall on limited WASH services. Conclusion: This study revealed lower coverage of basic WASH services in dispensaries. An urgent need is required to improve the status of WASH in all the dispensaries and facilitate the provision of quality health care services, patient safety and reduce health care associated infections. 展开更多

Corduroy yarn is generally introduced in a fabric structure of garments due to developing different designs in terms of appearance of fabric which is called corduroy garment. In this study, both corduroy and denim garments have been made to develop a denim-like wash effect on corduroy garments that will create a new fashion, value addition and sustainability in washing technology. Both the garments are treated with the same washing process. Also, some physical properties have been investigated for both washed garments such as Washing Effect Test, Tear Strength Test, GSM Test, and Rubbing Test. Then a comparative study has been done on both washed garments. The appearance of washed corduroy garments is satisfactory. The physical properties also show a better result. Finally, a satisfactory result is achieved from this work. 展开更多

BACKGROUND Previous studies have found that hyperuricaemia(HUA)is closely related to intestinal flora imbalance.AIM The current study investigated the effects and safety of washed microbiota transplantation(WMT)on serum uric acid(SUA)levels in different populations.METHODS A total of 144 patients who received WMT from July 2016 to April 2020 in the First Affiliated Hospital of Guangdong Pharmaceutical University and had SUA data before treatment were selected.Changes in SUA levels before and after treatment were retrospectively reviewed based on short-term and mid-term effects of WMT regimens.SUA levels measured in the last test within 3 mo after the first WMT represented the short-term effect,and SUA levels measured in the last test within 3-6 mo after the first WMT represented the mid-term effect.The patients were divided into an HUA group(SUA>416μM)and a normal uric acid(NUA)group(SUA≥202μM to≤416μM)based on pretreatment SUA levels.RESULTS Average short-term SUA levels in the HUA group decreased after WMT(481.00±99.85 vs 546.81±109.64μM,n=32,P<0.05)in 25/32 patients and returned to normal in 10/32 patients.The shortterm level of SUA reduction after treatment moderately correlated with SUA levels before treatment(r=0.549,R²=0.300,P<0.05).Average SUA levels decreased after the first and second courses of WMT(469.74±97.68 vs 540.00±107.16μM,n=35,and 465.57±88.88 vs 513.19±78.14μM,n=21,P<0.05).Short-term and mid-term SUA levels after WMT and SUA levels after the first,second and third courses of WMT were similar to the levels before WMT in the NUA group(P>0.05).Only 1/144 patients developed mild diarrhea after WMT.CONCLUSION WMT reduces short-term SUA levels in patients with HUA with mild side effects but has no obvious effect on SUA levels in patients with NUA. 展开更多

Phytoremediation is a cheap and environmentally friendly technique in which green plants in situ are used to clean the soil, sediments and water of heavy metals. This study investigated the phytoremediation potential of six naturally occurring macrophytes from Nange (a stream in Buea municipality where cars have been driven into and washed for over 20 years). Plant samples were collected before and after car wash, then analysed for copper, zinc, lead and cadmium accumulation. There was an increase in concentration of all the four heavy metals in water after carwash point, with Zn having the highest concentration (0.27 mg/L). Mean concentration of the heavy metals in the water showed that Zn and Pb had the highest concentrations (0.24 mg/L each) while the least concentration was obtained in Cu (0.12 mg/kg). Heavy metal concentrations in the sediments were higher after car wash point than before. Cadmium had the highest concentration (5.58 mg/kg) while Cu had the least (0.75 mg/kg). <em>Ludwigia peruviana</em> had the highest BAFs for all the heavy metals (22.95 for Cu, 33.41 for Zn, 21.79 for Pb and 7.85 for Cd). Species with the leasts were: <em>Anubias barteri</em> for Cu (7.16), <em>Polygonum persicaria</em> for Zn (14.28), <em>Rorippa nasturtium-aquaticum</em> for Pb (11.60) and <em>Vallisneria spiralis</em> for Cd (1.98). <em>L. peruviana</em> had the highest BAC values (Cu = 10.11, Zn = 14.73, Pb = 11.39, Cd = 3.85) and BCF values (Cu = 12.84, Zn = 18.67, Pb = 10.40, Cd = 4.00). <em>A. barteri</em> had the highest TF (Cu = 1.49, Zn = 1.27, Cd = 1.99) except for Pb where both <em>A. barteri </em>and <em>L. peruviana</em> each had a TF of 1.10. While all the six plants were found to be good accumulators of the heavy metals, <em>L. peruviana</em> showed remarkable efficiency indicating that the species is a good candidate for cleaning such environments. 展开更多

Denim was produced in the city of Nîmes in France and was originally called the serge de Nîmes.The word denim is an English colloquialism of the French term:"denim."Day by day Bangladesh denim sector very much developed and helps to increase productivity.Bangladesh have seen a significant increase in investing in denim fabric manufacturing,increasing the country’s production performance by reducing fabric dependence on imports.It is important due to its aspects of durability,and not easily torn which benefited physical laborers much.The government also plays a vital role in denim textile industry.This paper shows different section of denim textile industry such as:sewing section,cutting section,washing,IE and finishing department.The main aim of this paper is how to role all the sec­tion of denim textile industry.Textile education is insufficient without in­dustry attachment,which bridges the gap between theoretical and practical aspects and acclimates students to the industrial world.We can gain about theoretical development on an industrial level from this attachment.We can understand more about the machines used in various departments,their technical specifications,characteristics,operating system,and so on,and we believe that without this type of industrial connection,it is impossible to obtain industry-based information about textile engineering adequately.The Industrial Attachment on Denim Manufacturing Technology was used to organize this study(sewing section,cutting,IE,washing section,CAD Section,and finishing department.Various operating procedures for the production of denim in the industry are presented in this paper.The tech­nique and process of several procedures and processes are presented here such as machine specifications,manpower,maintenance,layout of the dif­ferent section,dye processes and wet processes. 展开更多

Twenty-seven specimens were tested to investigate the uniaxial compression behaviour of an innovative standing support for underground space applications.The innovative standing support consisted of an external fibre reinforced polymer(FRP)jacket and the infill column made of cementitious grout,tailings and coal wash rejects.Effects of the FRP layers number and water to the cementitious grout(w/g)ratio were evaluated.Test results indicated that lower w/g ratios produced stronger infill columns.With FRP confinement,the standing support demonstrated strain-hardening loading characteristics with a significant improvement in both strength and ductility.The highest strength and strain of the specimens achieved was 58.4 MPa and 11.8%respectively.Compared with the unconfined specimens,the confinement with four FRP layers increased the specimen strength and associated strain up to 3.6 and 27.0 times respectively.A correlation between the compressive strength of the infill material and the ultrasonic pulse velocity was also investigated.Furthermore,a simple design-oriented model was proposed to predict the peak strength and the corresponding strain of the innovative standing support. 展开更多

A sophorolipids(SLs)micro-emulsion in Winsor type Ⅰ form was used for crude oil contaminated soil washing treatment.The micro-emulsion shows higher oil removal rate than SLs aqueous solution and diesel oil.The type Ⅰ micro-emulsion with w(SLs)=6%,w(NaCl)=1%,w(diesel)=13.36% gave a high oil removal rate of 95.6% and the eluate remained in type Ⅰ state.The recovered oil showed lower viscosity,mainly caused by the entering of diesel from the micro-emulsion phase into the oil phase and the lower removal rate of the heavier components,such as the resin and asphaltene.The initial heavily saline-alkaline soil changed into mildly saline-alkaline state after washing treatment,favoring the germination and growth of plants,with ryegrass showing better germination and growth effect than alfalfa.The ryegrass showed good phytoremediation effect on the contaminated soil after SLs micro-emulsion washing.The combination process of SL micro-emulsion washing and ryegrass phytoremediation is prospective for oily soil treatment. 展开更多

The application of high-sulfur petroleum coke after desulfurization in aluminum electrolysis anodes is an important development trend. However, removing sulfur from high-sulfur petroleum coke is still a significant challenge.This study proposes alkali calcining and reflux washing to examine the impacts of temperature, particle size, the mass ratio of Na_(2)CO_(3) to NaOH, and total sodium addition on the desulfurization efficiency and mechanism. The results show that the desulfurization rate increases with increasing temperature, increasing total sodium content, and decreasing particle size. The addition of alkali can significantly reduce the opening-ring reaction temperature of thiophene and convert organic sulfur into inorganic sulfur(Na_(2)S). Three washing methods were compared, and reflux washing was selected to separate inorganic sulfur(Na_(2)S) from calcined petroleum coke. The sulfur content in petroleum coke decreased from 7.29% to 1.90%, with a desulfurization rate of 80.13% under optimal conditions. The petroleum coke was analyzed before and after desulfurization using X-Ray diffraction(XRD), Scanning Electron Microscopy(SEM), Infrared Spectroscopy(IR), Thermogravimetric Analysis and Differential Scanning Calorimetry(TG-DSC), Gaschromatography-mass Spectrometry(GC-MS). The results show that thiophene and benzothiophene in petroleum coke are decomposed and converted into octane and ethyl cyclohexane. These new observations are expected to provide further understanding and guidance for the utilization of highsulfur petroleum coke. 展开更多

Understanding why individuals do or do not adopt optimal water, sanitation, and hygiene (WASH) practices is critical to designing successful behavior change interventions. However, policy makers and program implementers often fail to obtain the context-specific information on behavioral determinants of WASH practices. This two-stage, randomized survey among 5000 female primary caregivers in the Lake Zone of Tanzania assessed associations between behavioral determinants and a range of hygiene and sanitation practices. Behavioral determinants of hygiene were almost always significantly associated with cleaning one’s own hands after cleaning the baby’s bottom and being able to show at least one place where family members wash their hands. In regression models, those who knew when to wash their own hands (OR = 1.8, 95% CI: 1.5, 2.1) and their child’s hands (OR = 1.5, 95% CI: 1.3, 1.7) and mothers who thought that their female friends washed their hands after cleaning the baby’s bottom (OR = 5.5, 95% CI: 4.5, 6.7) were significantly more likely to frequently clean their own hands after cleaning the baby’s bottom. This research suggests that in the Lake Zone of Tanzania, numerous determinants are associated with hygiene practices. Identifying context-specific determinants of WASH behaviors is the first step toward developing effective interventions. 展开更多

Introduction: Hand hygiene (HH) is an effective way to fight infections in healthcare settings. The general purpose of our study was to explore the knowledge, attitudes and practices of health care providers on HH at Dapaong regional hospital (DRH). Methodology: This was a prospective, descriptive cross-sectional study conducted from March to June 2022 in the DRH wards. Data were collected using a questionnaire and observation grid. Results: 90 care providers were surveyed. Males and non-physician personnel predominated with 57.8%, and 94.4% respectively. The survey on staff’s knowledge reported: 31.1% of practitioners did not wash their hands on arrival and departure in services. 24% did not know the difference between simple hand washing (SHW) and hygienic hand washing (HHW). 23.3% did not know the type of soap to use for HHW. The caregivers did not know the type of hand washing (HW) required after a septic and non-septic procedure in respectively 41.6%, and 37.8%. They did not know that there are two types of hand antiseptics (45.4%), nor the amount of antiseptic for HW (78.9%). The survey on staff’s attitude regarding HW found that: 70% did not remove all jewels prior HW, and 51.1% did not know that wearing gloves cannot replace the HW. For HW Staff Practice: 62.2% did not wash their hands before treatment. 91.1% did not spread the soap on their hands and forearms after wetting them. 65.55% did not rinse hands from nails to elbows. Conclusion: The HH was poorly known, the attitude of the staff was dangerous in relation to the HH and the practice of HH was very inadequate at the RHC-Dapaong. As a result, there is a need to retrain staff to increase their capacity to prevent care-related infections and enhance patient safety in the hospital. 展开更多

The sulfur phase in high sulfur-containing bauxite was studied by an X-ray diffraction analysis and a chemistry quantitative analysis.The methods for the removal of different shaped sulfur were also discussed.The results show that sulfur phases in high sulfur-containing bauxites exist in the main form of sulfide sulfur (pyrite) or sulfate sulfur,and the main sulfur forms of bauxites from different regions are not the same.Through a combination of an X-ray diffraction analysis and a chemistry quantitative analysis,the sulfur phases of high sulfur-containing bauxite could be accurately investigated.Deciding the main sulfur form of high sulfur-containing bauxite could provide theoretical instruction for choosing methods for the removal of sulfur from bauxite,and an oxidizing-roasting process is an effective way to remove sulfide sulfur from high sulfur-containing bauxite,the content of S^2-in crude ore in the digestion liquor is above 1.7 g/L,but in the roasted ore digestion liquor,it is below 0.18 g/L.Using the sodium carbonate solution washing technology to wash bauxite can effectively remove sulfate sulfur,the content of the total sulfur in ore is lowered to below 0.2% and can meet the production requirements for the sulfur content. 展开更多

The experimental results show that under the optimum hydrothermal conversion conditions, i.e., 50% NaOH (mass fraction) solution, NaOH/tionite mass ratio of 4:1, reaction temperature of 240 ℃reaction time of 1 h and oxygen partial pressure of 0.25 MPa, the titanium was mainly converted into Na2TiO3, and the conversion was 97.2%. The unwanted product Na2TiSiO5 remained stable in water washing, and its formation was prevented by improving NaOH concentration. In water washing process, about 97.6% of Na+ could be recycled by washing the hydrothermal product. The NaOH solutions could be reused after concentration. 96.7% of titanium in the washed product was easily leached in H2SO4 solution at low temperatures, forming titanyl sulfate solution to further prepare TiO2. 展开更多
