Hand washing as an effective technique for intestinal parasites controlamong school children in Gaza city

Background/aim: Hand washing is one of the most effective ways to prevent the spread of many types of infection and illness especially those spread through oral-fecal route. Intestinal parasites are parasites that populate the gastrointestinal tract in humans and other animals they can live throughout the body, but most prefer the intestinal wall. Intestinal parasitic infections are among the most common infections worldwide. The high prevalence of parasites infection in children is attributed to many factors, particularly environmental and personal hygiene We aimed to assess the using of hand washing technique for the controlling of intestinal parasites infection among school children in Gaza. Method: 508 children from primary school children were examined for the presence of intestinal parasites and then the infected children were divided into case and control groups based on match criteria. Hand washing and health education were applied on intervention group and then the second stool sample was examined from both case and control groups. Results: the prevalence of intestinal parasitic among school children was 23.2%. Entamoeba histolytica/dispar was the highest protozoa detected among school children in this study (73.3%). The prevalence of intestinal parasites among children was reduced after the application of hand washing technique from 23.2% to 15.5%, the prevalence of intestinal parasites in male higher than female due to variant behavior of both sexes. Conclusion: It is concluded that hand washing has a significant role in reducing intestinal parasitic infection among school children. It is recommended that hand washing should be delivered to all school children in Gaza strip.

Ultrasound-assisted soil washing processes using organic solvents for the remediation of PCBs-contaminated soils

Ultrasonic soil washing processes using organic solvents were investigated for the development of novel remediation technologies for persistent organic pollutants (POPs)- contaminated soils. Aluminum foil erosion was first tested to understand sonophysical activity in water, methanol (polar) and n-hexane (nonpolar) in a 28 kHz double-bath-type sonoreactor. Significant sonophysical damage on the aluminum foil was observed at the antinodes for all solvents, and the order of degree of sonophysical damage was as follows: water > methanol > n-hexane. Subsequently, conventional (mechanical mixing only) and ultrasonic soil washing (mechanical mixing and ultrasound) techniques were compared for the removal of polychlorinated biphenyls (PCBs) from soil. Two types of contaminated soils, fresh (Soil A, C0 = 2.5 mg/kg) and weathered (Soil B, C0 = 0.5 mg/kg), were used and the applied soil-to-liquid (S:L) ratio was 1:5 and 1:10 for methanol and n-hexane, respectively. The polar solvent significantly increased washing efficiencies compared to the nonpolar solvent, despite the nonpolar nature of the PCBs. Washing efficiency was significantly enhanced in ultrasonic soil washing compared to conventional washing, owing to macro- and micro-scale sonophysical actions. The highest washing efficiencies of 90% for Soil A and 70% for Soil B were observed in the ultrasonic washing processes using methanol. Additionally, a single operation of the ultrasonic washing process was superior to two sequential processes with conventional mixing in terms of washing efficiency, consumption of washing agents, treatment of washing leachate, and operation time. Finally, the removal of PCBs in an organic solvent (methanol) was investigated in photolytic and sonolytic processes for the post-treatment of soil washing leachate. A photolysis efficiency of 80% was obtained within 60 min of UV exposure for intensities of 1.0, 2.0, and 4.0 W/cm2. The primary mechanism of PCBs degradation is photolytic dechlorination. In contrast, no degradation was detected in the sonolytic process, as the excess organic solvent acted as a strong radical scavenger.

Ambient-air fabrication of stable mixed cation perovskite planar solar cells with efficiencies exceeding 22% using a synergistic mixed antisolvent with complementary properties

Perovskite solar cells (PSCs) employing formamidinium (FA) based mixed cation perovskites are inherently susceptible to moisture due to the easy bonding of their FA moieties with H2O. Thus, for the one-step antisolvent synthesis of FA-based devices, strictly controlled environment such as N2-filled glove box or dry room is essential, which makes the easy manufacturing of low-cost PSCs difficult. Here, utilizing the complementary properties of dibutyl ether (DB) and diethyl ether (DE), an innovative mixed antisolvent approach that is not sensitive to moisture is proposed. FA-based planar PSCs are fully synthesized under ambient-air conditions with a relative humidity of >40% using an antisolvent washing technique with mixed DB/DE and single DE. The lattice expansion induced by the binding of water molecules on the surface of FA-containing perovskites synthesized by a single antisolvent was predicted by calculations based on the density functional theory. It was verified that the resultant tensile stress was substantially reduced when mixed DB/DE was used. Planar PSCs based on the DB/DE mixed antisolvent treated (FAPbI3)0.95(MAPbBr3)0.05 and Cs0.01FA0.94MA0.05PbI2.85Br0.15 films exhibited the best power conversion efficiencies (PCEs) of 20.55% and 22.06%, respectively, which are record efficiencies among the ambient-air processed PSCs. In addition, planar perovskite devices treated with DB/DE antisolvent showed reduced hysteresis and high stability, wherein PCE of more than 90% was retained for up to 1300 h without encapsulation.

Calcareous and Gypsum Soils Lead Removal Using Two-Steps Washing

The soil washing technique is considered one of the quick and effective techniques for treating soil contaminated with heavy metals. In this study, EDTA-Na2 and Oxalic were used as washing solutions to removing Pb from calcareous and gypsum soils contaminated with Pb only and with Pb in addition to the used engine oil. The soil samples were contaminated with different concentrations of Pb only using Pb(NO3)2 to soils sample for each concentration separately then the sample was divided into two equal parts. The first part represents the calcareous and gypsum soil samples contaminated with Pb. The second part was taken after air-dried, and then the used engine oil was added and homogenized well. Five parameters (pH, contact time, Pb concentrations, temperature, and liquid/solid ratio) were applied to test their effect on Pb removal. In general, the results of this study varied based on the effect of the variables.

Superiority of Sustainable Ozone Wash Over Conventional Denim Washing Technique

Denim jeans need to be wet-processed in order to create a comfortable feel and a versatile look in the end product. The use of Ozone to finish denim jeans offers environmental and economic benefits by reducing rinse periods, water use, and energy consumption. Ozone is a specialized oxidant with a strong oxidation potential and can decolorize textile effluents, and it has a particular affinity for indigo. This paper will demonstrate why Ozone-based denim wash should be recognized as sustainable in different aspects of denim washing. The study observed that denim fabric finishing with Ozone particles has reduced garments processing time and requires less water and chemicals than the Conventional finishing method. Moreover, because of the low use of chemicals and water, ozone-based finishing produces a minimal amount of wastewater which eventually has less impact on the ETP as well as less effect on the environment than the traditional denim washing method. Also, it gives two times more production than conventional. With an in-depth evaluation of different washing points, this paper has concluded that Ozone-based wash is a promising finishing treatment for denim products.

Residual Li Compounds-Selective Washing Process for Ni-Rich Layered Oxide Cathode Materials for Li-Ion Batteries

The industrial manufacturing process for Ni-rich layered oxides for Li-ion batteries includes a washing step to remove residual Li compounds, such as LiOH and Li2CO3, from the oxide surface. However, Ni-rich layered oxides are deformed during a conventional water-based washing process, leading to the degradation of the oxide surface. In this regard, a significant challenge for Ni-rich layered oxides is to remove residual Li compounds without surface damage during a washing process. Herein, the residual Li compounds-selective washing process is introduced as a promising strategy for LiNi0.945Co0.04Al0.015O2 to suppress the degradation of the oxide surface during washing. The selectively hydrophobic LiNi0.945Co0.04Al0.015O2 powders are obtained through selective coating only on the LiNi0.945Co0.04Al0.015O2 surface with hydrophobic polydimethylsiloxane, leaving residual Li compounds uncoated. For this reason, the oxide surface is hydrophobic, whereas the residual Li compounds surface is hydrophilic. As a result, only residual Li compounds are selectively exposed to water and removed during washing, mitigating contact between the oxide surface and water. Eventually, this method suppresses the degradation of the LiNi0.945Co0.04Al0.015O2 surface during washing, resulting in the improved electrochemical performance compared to LiNi0.945Co0.04Al0.015O2 obtained through a conventional washing technique.

Research on Significance, Present Situation and Countermeasures of Spreading Seven-step Washing Technique in Colleges and Universities

Seven-step washing is a relatively mature hygiene method that can remove residual bacteria from hands. It has been widely mentioned in the prevention and control of COVID-19 in China, but it has not been fully and skillfully mastered by the general public. Colleges and universities are under great pressure from epidemic prevention and control. If the seven-step washing technique can be popularized, the pressure of epidemic prevention and control can be effectively alleviated in terms of short-term performance. In terms of long-term effect, it is also an inevitable requirement for promoting healthy China strategy and building a strong public health system. It is feasible for colleges and universities to promote seven-step washing techniques, but at present, no consensus has been formed in promoting seven-step washing techniques, and most colleges and universities still stay in the stage of knowledge publicity. It is suggested to continue to create a good campus atmosphere for the promotion of seven-step washing technique, incorporate the study of seven-step washing technique into the regular college entrance education system for freshmen, promote the involvement of medical staff in the study of seven-step washing technique, and strengthen the unified leadership of the promotion of seven-step washing technique in colleges and universities.

Simultaneous extraction and recovery of lead using citrate and micro-scale zero-valent iron for decontamination of polluted shooting range soils

Lead (Pb) contaminated soils pose serious risks to human health and the environment. One remediation technique that permanently removes Pb is chemical soil washing. This study investigated a modified chemical soil washing technique whereby Pb extraction in citrate solution and recovery of dissolved Pb by reductive precipitation (cementation) were simultaneously carried out in a single reactor by the addition of micro-sized zero-valent iron (mZVI) to decontaminate Pb-contaminated soil from a shooting range. Pb-loaded mZVI were then recovered by magnetic separation. The effects of mZVI dosage, citrate concentration, pH, and hydrodynamics on Pb removal were evaluated. Under acidic pH, Pb removal increased with increasing citrate concentration. The addition of mZVI suppressed Pb removal from 59.6 to 30% in 0.1 M citrate solution, which was attributed to dissolved Fe ions competing for free citrate ions to form soluble Fe-citrate complexes. Increasing the citrate concentration and shaking speed enhanced Pb extraction from the soil and subsequent recovery via cementation onto mZVI. Pb removal and recovery onto mZVI of up to 99.0% were achieved at citrate concentration of 0.7 M, pH of 5, and shaking speed of 165 strokes/min. The addition of mZVI during chemical soil washing in citrate solution not only extracted and recovered Pb from the contaminated soil but also eliminated the need to wash soil residues obtained after treatment because the bulk of dissolved Pb was sequestered from the solution.

Multimodal Strategy to Improve Hand Hygiene Compliance to Practices among Staff Nurses

Introduction and Background: Healthcare-acquired infections [HCAI] account for 10-30% of all hospitaladmissions, according to the World Health Organization [WHO]. An estimated 1.4 million people are infected withHCAI at any given time.1 As the burden of health-care-associated infections grows, so does the seriousness of diseaseand treatment difficulty, which is exacerbated by multi-drug-resistant pathogen infections.2 Health care providersare reverting to the fundamentals of infection control by employing common steps such as hand hygiene.3 TheWHO’s global initiative on patient safety programmers has made “Clean Care is Safer Care” a top priority.it is timefor developing countries to formulate the much-needed policies for implementation of basic infection preventionpractices in health care set-up.4Nurses, the “nucleus of the health-care system,” spend more time with patients than any other health-care worker, andtheir adherence to hand-washing protocols appears to be more important in preventing disease transmission amongpatients. Hand hygiene is thought to be the most important factor in preventing healthcare-associated infections(HAI). Hand hygiene programmes with a variety of components have been shown to increase compliance amonghealthcare workers and, as a result, minimise infections. One such initiative is the World Health Organization’simplementation of an evidence-based definition called “My five moments for hand hygiene.”5The investigator seeks to study the compliance to hand hygiene practices among staff nurses, working in the obstetricaland gynaecological wards. The research is an endeavour to increase the awareness and educate nurses about the needfor compliance to hand hygiene practices.Aim: A.The aim of this study was to see how well health care workers in the intensive care unit kept their handsclean (ICU)B. To determine the causes of noncompliance, andC. To investigate the effectiveness of a multimodal intervention approach in enhancing compliance.Methodology: This Quasi experimental one group pre-intervention and post intervention study compares thecompliance to hand hygiene practices before and after a multimodal interventional strategySetting: The study was conducted in ICU ward in hospitalResult: The study needed a sample size of 64 nurses to achieve an 80 percent power and a 5% error rate. A t testwas used to compare the mean pre- and post-test scores. ANOVA was used to examine the relationships betweenthe baseline variables. Hand hygiene enforcement among staff nurses increased dramatically from 45.31 percentto 65.78 percent following multimodal intervention strategies. (P0.0001) Hand hygiene techniques have improvedsignificantly (hand wash technique mean score increased from 5.97 + 1.284 to 8.16 + 1.158 (p 0.05) and hand rubtechnique score increased from 4.52 + 0.992 to 6.69 + 1.489 (p 0.05)).The private wards had considerably better handhygiene than the general wards.XI. Conclusion: The results of this study show that when multimodal interventional interventions were used, handhygiene compliance improved.

Water usage for hygiene practices among Tanjong Malim, Perak community during Movement Control Order (MCO) due to Covid-19

Due to the Covid-19 pandemic, the Government of Malaysia, via the Ministry of Health and National Safety Council, has imposed the Movement Control Order (MCO). In that order, the Ministry of Health and National Safety Council has given best practices for personal hygiene during the outbreaks to ensure public health precaution among Malaysians. Thus, the objective of this study is to survey the personal hygiene practices among Tanjong Malim, Perak Community During Movement Control Order (MCO) Due to Covid-19. A survey technique with a set of questionnaires was used to collect the required data on 383 respondents. The data were collected using a cross-sectional descriptive study, and percentage were utilised to determine the level of association. The results show that most of Tanjong Malim community practice a good hand washing technique with a mean value of 4.36 and SD = 0.66. They are also practising good personal hygiene by taking a shower immediately after returning home from public places with a mean value of 4.05 and SD = 0.82. They also wash their clothes immediately after returning home from public places (mean value of 3.90, SD = 0.87). On the other hand, the practice of separating clothes during washing is also high, with a mean value of 3.95, SD = 0.93. The personal hygiene attitude, namely washing their hand before and after touching something inside and outside the house, is also high with a mean value of 4.55, SD = 0.7 and 4.67, SD = 0.5, respectively. It is found that, due to the Covid-19 pandemic crisis, most of the respondents wash their hands at least twice a day, with a majority of 5 to 7 times a day (51.2%), followed by twice to 4 times a day (21.1%) and more than ten times a day ( 9.9%). However, the practising shower for more than 15 minutes and more than three times per day was low, with a mean value of 2.44, SD = 1.32, and 2.48, SD = 0.98, respectively. Hopefully, the findings of this study can be used by authorities as a basis to craft new guidelines for hygienic practices during the virus pandemic outbreak.

Conocimiento, actitud y conciencia de COVID-19 entre estudiantes de odontología preclínica y clínica: Una encuesta transversal en línea.

Objective: The aim of this study was to assess the understanding and perception of Coronavirus Disease 2019 (COVID-19) among the undergraduate preclinical and clinical dental students within Pakistan. Material and Methods: An online survey was developed by the researchers and conducted amongst the undergraduate students at various dental colleges of Pakistan. A pretested questionnaire was used and distributed using social media platforms. The questionnaire consisted of demographics, health status, perception related to general hygiene, understanding and learning attitudes of dental students. Knowledge scores and the attitude responses were compared with the demographics using independent t-test, one-way ANOVA and chi-square, as appropriate. Results: A total of 800 undergraduate dental students responded to the survey, out of which 304(38%) were males and 496(62%) were female students. Students in pre-clinical years were 600(75%), while 200(25%) students were in the clinical years. The knowledge of clinical students regarding COVID-19 was statistically higher (4.71/6), compared to the students in pre-clinical years (4.49/6) (p=0.004). Both groups showed adequate knowledge regarding the route of transmission, symptoms and origin of COVID-19, and COVID-19 being a threat to life. Clinical students did not want to re-use the face mask (75%), compared to the preclinical students (68%) (p-0.048). Students in clinical years reported more awareness regarding the recommended hand washing technique during COVID-19 (p-<0.001). Conclusion: It can be concluded that dental students in clinical years have adequate knowledge regarding the COVID-19 as compared to the preclinical students. The study identifies all areas where preclinical and clinical students lack basic knowledge. This should be compensated by arranging different webinars and online courses to increase the understanding of both clinical and preclinical students during the pandemic.

Novel methyl‐orange assisted core‐shell polyaniline‐silver nanosheets for highly sensitive ammonia chemiresistors

AbstractA cost‐effective, eco‐friendly, one‐pot synthesis of a new class of homogenous core‐shell polyaniline‐silver nanocomposite was fabricated with the assistance of supramolecular aggregates of amphiphilic methyl‐orange (MO) and oxidant ions of silver nitrate (AgNO3). The morphology of nanocomposite transforms from spherical (core‐shell type: PA‐1) to plate‐like polygonal particles (PA‐2) with surge in concentration of AgNO3. The strong contrast of the TEM images depicts the presence of silver (Ag) at core and polyaniline (PAN) at the shell. The core‐shell structure of the synthesized nanocomposite was confirmed using KCN washing technique. The SAED pattern reveals the hexagonal nature of PAN‐Ag hybrid nanosheets with [111] orientation with interplanar spacing around 2.4 Å corresponding to face‐centered‐cubic structure of Ag. The X‐ray diffraction spectra reveal the crystalline nature of the hybrid. Furthermore, the chemiresistors fabricated using the PA nanocomposite was analyzed for ammonia (NH3) monitoring behavior. The fabricated room temperature chemiresistor was found to be highly sensitive (~47.1% sensitivity) towards low concentration (as low as 1 ppm) of NH3 with high selectivity and stability, which opens a new window for fabricating cost‐effective commercial sensors.

Efficient treatment of crude oil-contaminated hydrodesulphurization catalyst by using surfactant/solvent mixture

The purpose of this work is to investigate desorption efficiency for regenerating a crude oil-contaminated catalyst by using an ex-situ surfactant/solvent washing technique. We employed six types of surfactants and solvents for optimization, and established an optimal mixture of surfactant and solvent for the removal of crude oil from the contaminated catalyst. The efficiency of the surfactant/solvent mixture for the removal of crude oil from the contaminated catalyst was determined based on the mass ratio of surfactant to solvent, contact time, pH, and temperature. The raw catalyst, crude oil-contaminated catalyst, and after washing catalyst were characterized by interracial rheometer, zeta-potential analyzer, and scanning electron microscope. We found that the Brij-58/1,2-dimethylbenzene mixture could provide superior crude oil removal efficiency. At a higher mass ratio of 1,2-dimethylbenzene, the crude oil removal rate of the contaminated catalyst exceeds 95%. This result is attributed to the addition of the solvent to the surfactant solution. The solvent can significantly decrease the surfactant’s CMC and increase the micelle’s number, thereby enhancing the mixture’s washing efficiency. Since aromatic solvents and crude oil components have similar structures in terms of polarity and aromaticity, the Brij-58/1,2-dimethylbenzene mixed system has a strong affinity for crude oil components.

Method for recovering cubic boron nitride abrasive grains from vitrified cBN stones – A preliminary study

In this work, a process is established for recovering cubic boron nitride (cBN) grains from fired vitrified cBN products. The abrasive grains are recovered by an acid washing technique. Two methods were used to recover the abrasive grains, namely with and without pre-heating. Shape and surface characteristics of the recovered grains were analysed through optical microscopy and Scanning Electron Microscopy (SEM). The recovery yield of abrasive grain and bond percentage present in the abrasive tool was measured experimentally. From the experimental results, the maximum recovery yield of 81 percentage was obtained in the pre-heated sample. Bond free abrasive grains are also obtained from the pre-heated samples and confirmed through elemental analysis.
