Objective: Breast cancer (BC) is the most common female malignancy in the world and Turkey. Its prevalence and mortality are surprisingly increasing at a rapid rate. The objective of this study was to determine the effectiveness of training sessions on women’s knowledge of relevant risk factors of BC and screening methods, screening behaviors and health beliefs among of healthy women in Turkey.Materials and Methods: In this study, in order to establish the efficiency of BC training, a semi-empirical single group pre-test & post-test research model was used. The data were collected by using a self-administered questionnaire and by using the Turkish version of Champion's health belief model scale (CHBMS). The pre-test was performed before the training and after one week of the training, post-test was performed with a questionnaire having the same content.Results: In total, 244 women participated in the study. The average age of the women was 39.44 (SD=1.06) years. The mean total knowledge score increased significantly (p

Aim: The aim of this research is to determine the effect of stoma self‐efficacy of people with stoma on their sexual function and satisfaction. Method: This descriptive research was carried out between November 2022 and May 2023. One hundred and forty people with stoma were included in the research. A descriptive information form, a visual analogue scale (VAS) for satisfaction with sexual life, the Stoma Self‐Efficacy Scale (Stoma SE) and the Arizona Sexual Experience Scale (ASEX) were used for the research. Results: According to the findings of the research, it was established that 90% of the participants had sexual dysfunction according to the ASEX. The average VAS satisfaction with sexual life score was 2.77 ± 3.19, the average Stoma SE Total score was 76.26 ± 19.63 and the average ASEX score was 21.62 ± 7.88. The VAS‐satisfaction with sexual life score of the participants had a positive relationship with the social self‐efficacy score and a negative relationship with the ASEX score. There was a negative relationship between the social self‐efficacy score and the ASEX score of the participants. It has been determined that the social self‐efficacy scores of the participants affect their ASEX and VAS‐satisfaction with sexual life scores. Conclusion: Development of care self‐efficacy is as critical as the development of social self‐efficacy for people with stoma. Development of social self‐efficacy by people with stoma can contribute to their sexual function and satisfaction with sexual life. [ABSTRACT FROM AUTHOR]

Aims and objectives: Determination of the effect of deep breathing exercise applied with Triflo on dyspnoea, anxiety and quality of life in patients who are hospitalized for COVID‐19 and have dyspnoea. Backround: COVID‐19 is a viral infection that can cause severe pulmonary disease. Deep breathing exercise with Triflo in patients with COVID‐19 may contribute to the reduction/elimination of dyspnoea and anxiety, and improvement of respiratory and quality of life. Design: The study was a randomized controlled clinical trial and conducted in accordance with the Consolidated Standards of Reporting Trials (CONSORT) 2010 guidelines. Methods: The study was conducted in the clinic of COVID‐19 of a tertiary hospital. A total of 44 eligible participants were enrolled from January to April 2021. Primary outcomes included oxygen saturation in the blood, respiratory assessment and dyspnoea level. Secondary outcomes included anxiety and quality of life. In the statistical analysis of the data, the independent sample t‐test, Wilcoxon test, Mann–Whitney U test and Spearman correlation were used to examine the intervention effect on primary outcomes and secondary outcomes, according to numbers, percentage, mean, standard deviation and conformity to normal distribution. Results: It was determined that the patients in the deep breathing group had a statistically significant shorter hospitalization time (3.04 ± 0.65), higher SpO2 level (97.05 ± 1.46) and higher quality of life (77.82 ± 6.77) compared with the patients in the usual care group (p < 0.05). Conclusions: Deep breathing exercise with Triflo increases the SpO2 level and quality of life in patients with COVID‐19 and contributes to a decrease in dyspnoea and anxiety levels. Moreover, the duration of hospital stay is shortened in patients who are applied deep breathing exercise with Triflo. Relevance to clinical practice: With deep breathing exercise applied with Triflo, respiratory rate reaches normal limits in a short time, SpO2 levels increase significantly, and quality of life improves significantly in patients with COVID‐19 pneumonia.

In the rapidly developing automotive technology, the efforts to achieve high performance with less fuel consumption is one of the most important issues today. The purpose of the supercharged systems developed for this reason is to send more air into the cylinder. For high engine performance and low exhaust emission values, the intake air temperature, which is heated in the turbo-compressor and has the oxygen concentration (the amount of oxygen in the unit air) decreased, must be kept at certain levels. Therefore, the heated air between the compressor outlet and the cylinder inlet must be cooled. In this study, different types of intercoolers were designed and analyzed with the help of ANSYS Fluent (CFD) program, and optimum conditions were tried to be obtained by comparing them with each other.

Aim Methods Results Conclusion Early diagnosis and screening of breast cancer are of vital importance in the fight against the disease. It is crucial to identify the underlying barriers that prevent women from undergoing mammography and to develop necessary strategies to overcome these obstacles. The purpose of this study was to adapt “The Perceived Barriers of Mammography Scale (PBMS‐23)” into Turkish and to conduct a validity and reliability study.This study used a methodological approach. The study was conducted with 233 women admitted to the Gynecology Outpatient Clinic of a university hospital. Data were collected by using the Introductory Information Form, PBMS‐23, Champion's Health Belief Model Scale for Mammography Screening (CHBMS‐MS). Psychometric properties of the scale were tested with content validity, confirmatory factor analysis, convergent validity, and test–retest reliability coefficient.Content validity confirmatory factor analysis resulted in 휒2/SD = 1.67; CFI = 0.97, NFI = 0.92, GFI = 0.86, RMSEA = 0.054. The scale had a Cronbach's alpha of 0.87, while the subscales had Cronbach's alpha values of 0.34 to 0.80. The intraclass correlation coefficient values calculated for the test–retest reliability were between 0.83 and 0.96 for the subscales and 0.96 for the overall scale. There is a positive and statistically significant relationship (p < 0.01) between the CHBMS‐MS barriers dimension and prejudices dimension scores and all subdimensions and the total of the PBMS‐23.The PBMS‐23 was accepted as a valid and reliable tool with 23 items and eight‐factor structure that can be useful in measuring Turkish women's barriers to mammography.

Surgical patients may experience inadvertent perioperative hypothermia, a condition that can cause a variety of complications, including surgical site infection (SSI). The authors of this systematic review used the Preferred Reporting Items for Systematic Review and Meta‐Analysis Protocols guidelines to examine the role of perioperative hypothermia in the development of SSI. The authors searched the PubMed, Cumulative Index Nursing and Allied Health Literature, Cochrane, and ScienceDirect databases for eligible articles published between January 2008 and November 2018 and identified seven studies that met the inclusion criteria. The results of this review indicate that the relationship between hypothermia and SSI is closely related to the type of the surgical intervention performed (eg, emergent, colorectal), and that severe hypothermia (eg, <35.0° C [95.0° F]) can increase the risk of developing an SSI. Perioperative nurses should monitor patients for inadvertent hypothermia and prevent its occurrence when possible. [ABSTRACT FROM AUTHOR]

In this experimental work, raw cottonseed oil was converted by KOH-catalyzed transesterification reaction with methyl alcohol to the cottonseed oil methyl ester (biodiesel) and then tested in a single cylinder, four strokes and direct injection diesel engine at the constant engine speed (2000 rpm) under different engine loads. The composition and the fuel-related properties of produced biodiesel were determined by using gas chromatography (GC) and related instruments. An increase in brake specific fuel consumption (BSFC) and decrease in brake thermal efficiency (BTE) for fuel blends were observed compared with diesel fuel. Compared with diesel fuel, exhaust emissions were found to be lower in carbon monoxide, hydrocarbon, nitrogen oxides and smoke with the use of fuel blends. It was concluded that cottonseed oil methyl ester-diesel fuel blends could be substituted for the diesel fuel without any modifications in diesel engines, with better environmental characteristics of fuel blends.

Biodiesel is an alternative diesel fuel, which is obtained from renewable biological sources such as vegetable oils and animal fats. When biodiesel is produced from food-grade vegetable oils, its the cost increases. To produce biodiesel an economically suitable , its cost must be lowered. The cost of biodiesel can be lowered, when it produces from low-cost feedstocks such as used frying oils and animal fats. Animal fats are highly viscous and mostly in solid form at ambient temperature that they need modifications before using them in diesel engines. The viscosity of animal fats can be reduced using transesterification process, emulsification and pyrolisis. Among these methods, the most commonly used process is transesterification reaction. In this literature review, using animal fat as a fuel for diesel engines is examined. [ABSTRACT FROM AUTHOR]

In this study, the effect of blends of iso-propanol and unleaded gasoline on exhaust emissions of a spark-ignition engine were experimentally investigated. Exhaust emission tests were conducted on a four-stroke, four cylinder and direct injection spark-ignition engine. The engine tests were performed at three-fourth throttle opening position at four various speeds in the range of 1000-4000 rpm with 1000 rpm period. The experimental results compared with unleaded gasoline showed that emissions of carbon monoxide (CO) and hydrocarbon (HC) decreased with iso-propanol-unleaded gasoline blends while carbon dioxide (CO2) emission increased.

Biodiesel fuels is one of the most attractive alternative fuels to reduce both emissions and petroleum based fuel consumption resulted from diesel engines. Therefore, the effects of biodiesel fuels on long-term engine operation and deposits in engine are considerably important, when biodiesel was evaluated as the alternative fuel for diesel engines. In this study, a 100 h engine test was performed on a single cylinder diesel engine using diesel fuel and tallow methyl ester as biodiesel fuel in order to compare the effects of the fuels on engine operation and deposits. The biodiesel was blended with 80 vol% diesel fuel and 20 vol % tallow methyl ester. Also, short-term engine performance and emissions were investigated and compared using both fuels. The test engine was disassembled before and after the experiment to determine the difference and clean carbon deposits. Experimental results were similar for both fuels in long-term engine tests, and indicated that the engine was satisfactorily operated for 100 hours with blend fuel. Deposits in engine at the end of the 100 h test were comparable in amount, but slightly different in color and adhesive, with the blend fuel when compared with those of diesel fuel. Besides, the blend fuel was comparable with the performance of diesel fuel and the exhaust emissions were lower than that of diesel fuel. It is concluded at the results of engine tests; the blend fuel can be a suitable alternative fuel for diesel engines to substitute diesel. [ABSTRACT FROM AUTHOR]

Abstract: In this study, a substitute fuel for diesel engines was produced from inedible animal tallow and its usability was investigated as pure biodiesel and its blends with petroleum diesel fuel in a diesel engine. Tallow methyl ester as biodiesel fuel was prepared by base-catalyzed transesterification of the fat with methanol in the presence of NaOH as catalyst. Fuel properties of methyl ester, diesel fuel and blends of them (5%, 20% and 50% by volume) were determined. Viscosity and density of fatty acid methyl ester have been found to meet ASTM D6751 and EN 14214 specifications. Viscosity and density of tallow methyl esters are found to be very close to that of diesel. The calorific value of biodiesel is found to be slightly lower than that of diesel. An experimental study was carried out in order to investigate of its usability as alternative fuel of tallow methyl ester in a direct injection diesel engine. It was observed that the addition of biodiesel to the diesel fuel decreases the effective efficiency of engine and increases the specific fuel consumption. This is due to the lower heating value of biodiesel compared to diesel fuel. However, the effective engine power was comparable by biodiesel compared with diesel fuel. Emissions of carbon monoxide (CO), oxides of nitrogen (NO x ), sulphur dioxide (SO2) and smoke opacity were reduced around 15%, 38.5%, 72.7% and 56.8%, respectively, in case of tallow methyl esters (B100) compared to diesel fuel. Besides, the lowest CO, NO x emissions and the highest exhaust temperature were obtained for B20 among all other fuels. The reductions in exhaust emissions made tallow methyl esters and its blends, especially B20 a suitable alternative fuel for diesel and thus could help in controlling air pollution. Based on this study, animal tallow methyl esters and its blends with petroleum diesel fuel can be used a substitute for diesel in direct injection diesel engines without any engine modification.
