A MODEL FOR DETERMINING RIDER INDUCED ENERGY LOSSES IN BICYCLE SUSPENSION SYSTEMS.

SUMMARY The energy dissipated by the suspension systems used for off-road bicycles is a major concern due to the limited power source in cycling. Rider induced energy losses are those that arise from the muscular action of the rider. The purpose of this study was to develop and verify a dynamic model of a seated cyclist riding an off-road bicycle up a smooth road. With the absence of terrain irregularities, all suspension motion was rider induced. Knowing the stiffness and dissipative characteristics of the suspension elements, the power dissipated by the suspensions was calculated. Simulation results were compared to suspension deflections that were experimentally measured for a cyclist riding a commercially available dual suspension bicycle up a 6% grade at 6.5m/s. For this particular case, no fork motion was observed in the experiments which was consistent with the simulation results. For the rear suspension, the mean and amplitude of the largest harmonic were experimentally determined to be 6.6 and ±2.

Teachers’ Sociodemographic Characteristics, Psychological Distress, Job Satisfaction, and Their Willingness to Include Children with Special Needs in Regular Classes

Advancing inclusive education in countries where children with special needs (CWSNs) are yet to be meaningfully included in regular schools will ensure the progress of Goal 4 of the Sustainable Development Goals. One potent determinant to the effective inclusion of CWSNs is teachers’ intention and efforts to integrate them into their classes. Yet, there is still inadequate evidence in the existing body of literature that will help stakeholders understand the psychosocial variables that will impact their intentions and efforts to include CWSNs in their classes. In view of this, our study determined the association between teachers’ sociodemographic characteristics, psychological distress, job satisfaction, and their willingness to include CWSNs in their classes using a hierarchical regression model. The sample size is made up of 502 secondary school teachers in Anambra State. Our model showed the potency of sociobiological and motivational factors on teachers’ inclusive education willingness of CWSNs in their classes. Teachers’ age, years of teaching experience, and job satisfaction are significant predictors of their inclusion willingness for CWSNs. Teachers’ psychological distress did not significantly predict their inclusion willingness for CWSNs. The significance and implications of our findings were underscored.
TWENTY-YEAR TRENDS IN ANTIMICROBIAL RESISTANCES AMONG PSEUDOMONAS AERUGINOSA CLINICAL ISOLATES

We retrospectively analyzed the antimicrobial data of P. aeruginosa strains isolated from hospitalized subjects and outpatients over a 20-year period (2000-2019). A total of 2,588 unique P. aeruginosa strains, 588 from outpatients (23 %) and 2,000 from hospitalized subjects (77 %), were retrieved. Except gentamicin and ciprofloxacin, which showed significant antibiotic decreasing trends, all the antimicrobial agents tested did not show significantly changes in both groups (p < 0.01). There were significant increasing resistance trends for all antibiotics, except gentamicin and ciprofloxacin in P. aeruginosa strains isolated from respiratory tract samples (p < 0.05), and for meropenem and piperacillin-tazobactam in urine samples from subjects with and without urinary catheter (p < 0.05). Moreover, there was a significant increase in multidrug resistant isolates (p < 0.05). Monitoring antibiotic resistances at local and regional levels are required in order to reduce inappropriate antimicrobial consumption, to increase the focus on antimicrobial stewardship.

Environment-Sensitive Fluorescent Labelling of Peptides by Luciferin Analogues

Environment-sensitive fluorophores are very valuable tools in the study of molecular and cellular processes. When used to label proteins and peptides, they allow for the monitoring of even small variations in the local microenvironment, thus acting as reporters of conformational variations and binding events. Luciferin and aminoluciferin, well known substrates of firefly luciferase, are environment-sensitive fluorophores with unusual and still-unexploited properties. Both fluorophores show strong solvatochromism. Moreover, luciferin fluorescence is influenced by pH and water abundance. These features allow to detect local variations of pH, solvent polarity and local water concentration, even when they occur simultaneously, by analyzing excitation and emission spectra. Here, we describe the characterization of (amino)luciferin-labeled derivatives of four bioactive peptides: the antimicrobial peptides GKY20 and ApoBL, the antitumor peptide p53pAnt and the integrin-binding peptide RGD. The two probes allowed for the study of the interaction of the peptides with model membranes, SDS micelles, lipopolysaccharide micelles and Escherichia coli cells. Kd values and binding stoichiometries for lipopolysaccharide were also determined. Aminoluciferin also proved to be very well-suited to confocal laser scanning microscopy. Overall, the characterization of the labeled peptides demonstrates that luciferin and aminoluciferin are previously neglected environment-sensitive labels with widespread potential applications in the study of proteins and peptides.
Appearance Retention of Carpets Using Image Analysis; Correlation with Subjective Method

This study compares a new objective method for measuring texture retention in carpets to the usual subjective technique. The effect of mechanical wear on the texture of a range of nylon cut-pile carpets is examined using the image analysis techniques of covariance and co-occurrence analysis, and the results correlated with the subjective method. The image analysis methods provide reliable measurements of the retention of carpet texture. Such a consistent and reliable instrumental method could play an important role in product design, performance evaluation and quality control in carpet manufacture.

SPECTRAL-DOMAIN OPTICAL COHERENCE TOMOGRAPHY IN PATIENTS TREATED WITH HYDROXYCHLOROQUINE

Background: The patients with early retinopathy can be asymptomatic with normal fundus before any signs of maculopathy appear; hence, screening for early detection in the premaculopathy stage is recommended. Spectral domain optical coherence tomography (SD-OCT) detects early structural damage to macula in patients on hydroxychloroquine (HCQ) therapy. Aim of the work: To evaluate the role of spectral-domain optical coherence tomography (SD-OCT) in early detection of hydroxylchloroquine (HCQ) maculopathy. Patients and methods: This cross-sectional observational study was conducted between November 2017 and November 2019 on 100 adult female patients taking HCQ referred from the ophthalmology and rheumatology outpatient clinics of Ain Shams University Hospital. The age of the participants ranged between 25 and 60 years. Fifty age and sex matched healthy subjects were assessed as a control group. The study was conducted in accordance with the ethical standards stated in the Faculty of Medicine Ain Shams University, with informed consent obtained. Results: The mean central foveal thickness was found to be thinner in the hydroxychloroquine group than the normal controls, which was statistically significant (p value = 0.042). The upper, lower, nasal and temporal parafoveal thickness were thinner in the hydroxychloroquine group in comparison to that of the control group (p value = 0.001, 0.020, 0.001 & 0.001 respectively). The upper, temporal and lower perifoveal thickness showed statistically significant thinning in the hydroxychloroquine group (p value = 0.002, < 0.001 & 0.041 respectively) in all quadrants except the nasal quadrant which was not statistically significant (p = 0.169). No significant difference was detected between the two groups regarding ganglion cell complex thickness. Conclusion: Preclinical hydroxychloroquine toxicity can lead to early thinning in the central fovea as well as the parafoveal and perifoveal regions that is detected by SD-OCT.
The Influence of Convenience on the Usage of Learning Management System

The advancement in internet-based learning technologies together with the national agenda towards globalized online education in Malaysia have prompted the learning management system (LMS) to become an important channel for institutions of higher education to effectively deliver education to students. Since user resistance has been known to be a stumbling block in the implementation of the LMS, it is crucial for the institutions to acknowledge that comprehensive adoption by users relies heavily on user acceptance. Moreover, since some institutions may have even made it compulsory for students to use the LMS, user acceptance of the LMS should be studied in the sense that using LMS is likable and pleasurable. Although the features of the technical capability of the LMS are important, it has been asserted that having the feeling of personal convenience when using the LMS is even more important to the users. With the amount of financial effort and manpower involved in implementing the LMS by institutions in Malaysia towards fulfilling the online learning agenda of the nation, it is important to study whether the convenience factor as an individual impact can play the partial role of influencing Malaysian students’ satisfaction of the LMS which would in turn influence them to use the LMS. Based on the Information System Success Model by DeLone and McLean, this study establishes vital process factors regarding the LMS usage among university students in Malaysia. Hence, in this study, LMS usage by students is measured by the degree of students’ acceptance of the LMS. An online survey has been done to collect data from 212 students of two large public universities in Malaysia. Structural equation modeling has been used to test the relationships in the conceptual model. The results of data analysis using the PLS-SEM technique employed in the study have indicated that student satisfaction is positively influenced by factors of information quality, system quality, service quality and convenience. LMS usage has been found to be positively impacted by student satisfaction while student satisfaction has been found to have significant mediation effect. The findings from this study can be utilized by institutions committed towards having successful implementation of the LMS. In enhancing LMS usage by the students, the institutions of higher education can consider focusing on the necessary steps towards increasing student satisfaction. Meanwhile, to increase student satisfaction, apart from improving the information quality, system quality and service quality, institutions should also seriously consider promoting the LMS to the students by highlighting the individual impact of the LMS in terms of convenience.

This study was carried out during 2018/2019 and 2019/ 2020 seasons. On Valencia orange trees are grown in al kawamil orchard at the faculty of agriculture, sohag university, where the soil texture is sandy. The selected trees had the same vigor. This study aimed to throw some light on the effect of single and combined applications of some antioxidants (300 ppm ascorbic and 300 ppm salicylic acids), 1% magnesium and a mixture of micronutrients (300 ppm Fe, 200 ppm Zn, 200 ppm Mn) on some vegetative growth characters, fruit set %, fruit retention%, tree nutritional status, number of fruits per tree, yield and physical and chemical characteristics of fruits. Selecting the best-combined treatment from these antioxidants, magnesium and micronutrients responsible for gaining an economical yield is considered another target.
Antibody frequency for Toxoplasma gondii and Neospora spp. in domiciliated and stray cats from Araguaína, Tocantins, Eastern Amazonia

Toxoplasma gondii and Neospora spp. are protozoa that have a significant impact on animal health due to the diseases they cause in domestic and wild animals. The aim of the present study was to investigate the presence of antibodies against T. gondii and Neospora spp. in cats from northern Brazil. Serum samples were collected from 180 cats in the municipality of Araguaína, Tocantins and used to evaluate the presence of anti-T. gondii and anti-Neospora spp. antibodies using the indirect fluorescent antibody test, with a cutoff of 1:64 and 1:25, respectively. The association between infection and individual animal characteristics (age, sex, origin, breed, and clinical signs) was tested using univariate analysis, followed by multivariate logistic regression. We found that 48.3% (87/180) of the animals had anti-T. gondii (95% CI: 40.8%–55.90%) and 3.9% (7/180) had anti-Neospora spp. (95% CI: 1.6%–7.8%) antibodies. There was no association between age, sex, breed origin, clinical signs, and seropositivity for T. gondii. Cats of defined breeds were more likely to be infected by Neospora spp. (OR = 10.7). Therefore, we found a high rate of seropositivity for T. gondii and a high rate of occurrence of Neospora infections in cats from the Araguaína region. The exposure of the feline population to the studied coccidia indicates the need to monitor the feline population for these infections and underscores the importance of effective sanitary measures against such pathogens.
The effect of habitat structural complexity on gastropods in an arid mangrove wetland

Structural complexity of mangrove forests is thought to provide critical habitats for a variety of invertebrates. We studied the influence of habitat structure and sampling time on the gastropod diversity in Khuran mangrove ecosystem in the Persian Gulf. Sampling was conducted in two successive years (February and June 2018, February and June 2019) at two mangrove habitats i.e . , pneumatophore zone and mudflats. The gastropod assemblages were characterized by the dominance of specific taxa and low species richness. In total, 18 taxa were identified, including 14 species occurring in the mangrove forest and 16 species in the mudflats. Assimineidae dominated the assemblages in both mangrove habitats. Four species ( Mitrella blanda, Mitrella cartwrighti, Pellamora densilabrum, Pseudominolia sp.) were found only in mudflat habitats, while two species ( Bakawan rotundata, Peronia verruculata ) were found only in pneumatophore zones . The gastropod assemblage structure differed significantly between habitats and sampling dates. Of the environmental variables measured, distance-based linear models revealed that total organic carbon (TOC), and total nitrogen (TN) best explained the variation in gastropod assemblage structure. We suggest that conservation efforts should focus not only on preserving mangrove forests, but also upon protecting their adjacent bare mudflats as they provide habitat for various mangrove fauna.
Waste apple pomace conversion to acrylic acid: Economic and environmental assessment

The global demand for acrylic acid (AA) is increasing due to its wide range of applications. Due to this growing demand, alternative AA production strategies must be explored to avoid the exacerbation of prevailing climate and global warming issues since current AA production strategies involve AA production using fossil resources. Investigations on alternative strategies for AA production therefore constitute an important research interest. The present study therefore assesses waste apple pomace (WAP) as a feedstock for the sustainable AA produc-tion. To undertake this assessment, process models, based on two production pathways were designed, modelled and simulated in ASPEN plus® software. The two competing production pathways investigated include a process incorporating WAP conversion to lactic acid (LA), prior to LA dehydration to generate AA (denoted as the FD pathway) and another process involving WAP conversion to propylene, prior to propylene oxidation to generate AA (denoted as the TFO pathway). Economic and environmental performances of the FD and TFO pathways were assessed via the minimum selling price (MSP) and potential environmental impacts per h (PEI/h) metrics. The study was able to show that the FD pathway presented an improved economic performance (MSP of AA: US $1.17 per kg) performance compared to the economic performance (MSP of AA: US $1.56 per kg) of the TFO pathway. Crucially, the TFO process was shown to present an improved environmental performance (2.07 kPEI/h) compared to the environmental performance of the FD process (8.72 kPEI/h). These observations sug-gests that the selection of the preferred AA production will require a trade-off between the performance measures, and the integration of a multi-criteria decision assessment in future work.
Environmental analysis of new construction and maintenance processes of road pavements in Switzerland

The subject of this paper is an environmental analysis of processes needed to construct (material production, pavement construction, transport) and maintain (pavement deconstruction, recycling, material production, pavement construction, transport) representative Swiss asphalt, concrete and composite pavements (including subbase layers). The analysed environmental indicators are the IPCC Global Warming Potential indicator, the Ecological Scarcity Indicator and the Non-renewable Cumulative Energy Demand indicator. It is shown that material production processes have the largest impact on the values of the analysed indicators, and that pavement construction and deconstruction processes have a marginal impact on the analysed indicators in comparison to material production, transport and recycling processes. It is also demonstrated that the values of the IPCC Global Warming Potential indicator and the Ecological Scarcity indicator for the processes needed to construct and maintain concrete and composite pavements are higher than those for all processes required to construct and maintain asphalt pavements, due to the greater thickness of concrete and composite pavements. The values of the Non-Renewable Cumulative Energy Demand indicator are higher for processes applied to construct and maintain asphalt pavements than for concrete pavements, due to the use of bitumen within asphalt pavements, which causes a depletion of fossil energy resources.
