For any educator, knowledge about a pupil’s individual perception may strongly support teaching success. Within this context, we see the use of drinking water as daily behavior loaded with conceptions. We monitored the perceptions of two different samples, of high achieving 10th graders and of undergraduates in Biology. All participants responded to three closed and three open questions requesting individual statements about drinking water. All open questions were categorized via qualitative content analysis mainly revealing the perception of drinking water as a clean product, precisely controlled and drinkable with no need for worry. In general, some alternative conceptions did not seem differ in both samples over the time of about five years: For instance, many see our drinking water as purified in sewage plants. However, differences between individuals exist: For example, whether water is consumed as tap or bottled water. Here, some name water hardness as the reason to not drink tap water, because they think it is harmful (although the very same participants prefer bottled mineral water). Other conceptions seem to change over time, such as the estimation about the remaining time until our drinking water might be used up, or familiarity with the term “virtual water”. Summing up, we did find a positive attitude towards national drinking water policy, although major knowledge gaps need its mentioning. The relevance of these results and strategies for public and school teaching are discussed.展开更多

However, despite the need for accurate climate change risk assessment, significant misconceptions in key risk terms, including vulnerability and impact, could lead to risk miscalculations. These misconceptions around risk concepts derive from the lack of risk terms’ standardization and the gaps in an integrated and widely accepted methodology for assessing climate change risks. Risk assessment frameworks should follow the specialties of each element/sector it is applied on and the special features of each climate hazard. Also, risk assessment matrix should not follow specific design settings but it should better follow the needs of each study, so as to optimize the understanding of each risk. Through an extensive literature review, this is the first paper that identifies gaps, inconsistencies and misuses of climate risk concepts and suggests specific systemization and standardization of risk terms definitions. Finally, it develops a climate change risk assessment framework and matrix, focusing on sea level rise and extreme precipitation, which could be widely implemented in risk assessment of all elements at sea level rise and extreme precipitation risk.展开更多

The time and cost needed for conducting precise experimental investigation on shear behavior of unsaturated soils have encouraged several investigators to develop analytical, empirical, or semi-empirical models for predicting the shear behavior of unsaturated soils. However, most of the previously proposed models are for specimens subjected to the isotropic state of stress, without considering the effect of initial shear stress. In this study, a hydromechanical constitutive model is proposed for unsaturated collapsible soils during shearing, with consideration of the effect of the initial shear stress. The model implements an effective stress-based disturbed state concept (DSC) to predict the stress-strain behavior of the soil. Accordingly, material/state variables were defined for both the start of the shearing stage and the critical state of the soil. A series of laboratory tests was performed using a fully automated unsaturated triaxial device to verify the proposed model. The experimental program included 23 suction-controlled unsaturated triaxial shear tests on reconstituted specimens of Gorgan clayey loess wetted to different levels of suctions under both isotropic and anisotropic stress states. The results show excellent agreement between the prediction by the proposed model and the experimental results.展开更多

Infertility of tubal origin and secondary to infections are the most prevalent. The current study aimed to take stock of antibiotic therapy in infertility management without in Vitro Fertilization (IVF). Material and Methods A cross-sectional analytical study undertaken in University Clinics of Kinshasa and the Edith Medical Center, from January 2001 to December 2021. It involved 3754 patients who sought care for infertility and received antibiotics during the treatment. Results The mean age of the patients was 33.3 ± 5.7 years and ranged from 16 to 49 years. Most of them were nulliparous with secondary infertility. The average duration of infertility was 4.5 ± 3.6 years and ranged from 1 to 20 years. Most had a history of unsafe abortion and tubal obstruction. The pelvic infections were the main diagnosis. After antibiotic therapy, especially made of Doxycycline alone or in association 442 (8.8%) patients conceived. Conclusion In the low-income sub-Saharan setting, infection remained the common cause of infertility and doxycycline was found to be the most used and efficient antibiotics.展开更多

文摘Any everyday subject may trigger individual conceptions either scientifically correct or naively shaped (misconceptions, alternative conceptions). For any educator, knowledge about a pupil’s individual perception may strongly support teaching success. Within this context, we see the use of drinking water as daily behavior loaded with conceptions. We monitored the perceptions of two different samples, of high achieving 10th graders and of undergraduates in Biology. All participants responded to three closed and three open questions requesting individual statements about drinking water. All open questions were categorized via qualitative content analysis mainly revealing the perception of drinking water as a clean product, precisely controlled and drinkable with no need for worry. In general, some alternative conceptions did not seem differ in both samples over the time of about five years: For instance, many see our drinking water as purified in sewage plants. However, differences between individuals exist: For example, whether water is consumed as tap or bottled water. Here, some name water hardness as the reason to not drink tap water, because they think it is harmful (although the very same participants prefer bottled mineral water). Other conceptions seem to change over time, such as the estimation about the remaining time until our drinking water might be used up, or familiarity with the term “virtual water”. Summing up, we did find a positive attitude towards national drinking water policy, although major knowledge gaps need its mentioning. The relevance of these results and strategies for public and school teaching are discussed.

After antibiotic therapy, especially made of Doxycycline alone or in association 442 (8.8%) patients conceived. Conclusion In the low-income sub-Saharan setting, infection remained the common cause of infertility and doxycycline was found to be the most used and efficient antibiotics.
文摘The longitudinal ventilation strategy is commonly used for road tunnels in urban environment in Sweden.This is partly due to how tunnels in urban environment was planned and designed before the EU Directive[1](2004/54/EC)came in place.Even in new tunnels both to practical and economic reasons the use of longitudinal ventilation has been an outspoken demand from the Swedish road authority,SRA.Swedish law[2]requires that a risk analysis is carried out to demonstrate that an acceptable level of risk is achieved in the tunnels with longitudinal ventilation if there is a risk of queues.Otherwise transverse or semi-transverse ventilation strategy shall be used.During recent development,or a late awakening,it is clear that dense populated areas in Sweden will experience queues.This threatens the foundation of the Swedish modern tunnel safety concept which calls for enhancement.This paper presents the risk-reducing effect of three alternative strategies,enhancements package,focusing on evacuation safety for road users.It is a combination of traffic management,fixed firefighting systems,reduced distance between escape routes and regulation of traffic with dangerous goods.In addition,it provides a comprehensive review of safety system details,combined with a longitudinal ventilation concept.
