Rapid Microbial Growth in Reusable Drinking Water Bottles

Published on: 6th October, 2017

OCLC Number/Unique Identifier: 7286427113

Bacteria has been known to grow in pipes of water distribution systems and bottled drinking water. Its growth in reusable drinking water bottles is not clear even though they have become more popular and used by children and adults daily everywhere. This study found that there is an extremely high level of bacteria content and a rapid microbial growth in reusable drinking water bottles. The bacteria content tested by heterotrophic plate count (HPC) is in a range of 0-2.4x105 CFU/mL with an average of about 34,000 bacteria counts/ml for bottles used by children and 75,000 bacteria counts/ml for bottles used by adults. Bacteria number can quickly increases to 1-2 million counts/ml in the bottles one day later. Considering the high level of HPC bacteria content in the reusable drinking water bottles, it may be necessary to have some control measures to reduce the bacteria level and to minimize the associated likely health risk of the disease spreading since many people use reusable water bottles every day.

Rehabilitation of proximal humerus fractures: An environmental scan of Canadian physiotherapy practice patterns

Published on: 20th September, 2017

OCLC Number/Unique Identifier: 7286350490

Background: Proximal humerus fractures (PHFs) are common injuries particularly in older adults. Evidence-based protocols for PHF rehabilitation are lacking and physiotherapists use a variety of interventions. Purpose: To determine practice patterns and perceptions of physiotherapists who treat adults with PHF in Ontario, Canada. Method: A paper and pencil survey asking about respondent demographics and management of Neer Group 1 (minimally/nondisplaced) and complex (displaced 3- and 4-part) PHF was mailed to 875 randomly selected physiotherapists who were registered with the College of Physiotherapists of Ontario in 2013/2014 and working in practice areas likely to be accessed by adults with PHF. Results: The response rate was low (10%); 83 physiotherapists completed the survey - 80% had experience managing PHF. Respondents treated 1-5 individuals with PHF annually; more treated Neer Group 1 PHF (89%) than complex PHF (68%). Most individuals with PHF were older than 60 years (64%), female (76%) and accessed physiotherapy through a doctor’s referral (91%) more than 1 month post injury (33%). Main findings: Physiotherapists manage PHF using multi-component interventions and a minimum of 76% include the following elements: education and progression of passive, active assisted, active range of motion exercises and muscle retraining to build coordination and strength. Use of other elements was variable. The main factors influencing the treatment plan were the ability of the individual with PHF to comply, bone quality, and fracture type. Most respondents were unsure that there is sufficient PHF rehabilitation literature to guide treatment. Conclusions:This environmental scan is the first North American study to document practice patterns and attitudes of physiotherapists providing PHF rehabilitation. Elements used by physiotherapists in Ontario treating small numbers of individuals with Neer Group 1 or complex PHFs each year align well with the limited PHF rehabilitation literature available. Potential implications:Multi-disciplinary collaborations to design and conduct large, high quality, multi-centre prognostic studies and RCTs that evaluate the effectiveness of key aspects of non-surgical PHF rehabilitation in various patient groups are needed. Meanwhile, consensus guidelines should be developed in the context of region-specific physiotherapy service models to inform best practice in PHF rehabilitation management.

A qualitative method for determining the surfaces between asphalt layers using ABAQUS software

Published on: 25th April, 2019

OCLC Number/Unique Identifier: 8163588596

The analytical models are mainly combined with numerical equations for the problems of the pavement under the wheel load. Different assumptions can be considered, such as elastic asphalt and viscoelastic as well as static or dynamic load. Mainly on deformation at the bottom of asphalt and tension layers focus on subgrid. The pavement structure was considered as layers with uniform characteristics. Therefore, this analytical model calculates the three-dimensional contact tension between the wheel and the pavement and the shape of the contact area. Basis and subgrid are considered linear and the asphalt layers can be linear or viscoelastic. This model is based on the results of direct shear stress tests at an axial load constant. The curves obtained from this experiment can be defined by three parameters: the maximum shear stress (shear stress curve versus shear displacement), the interaction modulus between the layers (the same curve slope) and the friction coefficient after the failure. Due to the ability of ABACOUS software, this project is done with this software. One of the methods widely used to predict viscoelastic responses of asphalt mixtures is the finite element method. ABAQUS software is one of the tools that can simulate mixed asphalt behavior based on a finite element method, taking into account all the determinant parameters. The use of the Prony series is one of the common techniques for describing the viscoelastic behavior of asphalt mixtures in ABAQUS software. For this purpose, it is necessary to determine the parameters required for this field, including proven constants, moment elastic modulus, and asphalt mixture poison ratio. On the other hand, the determination of these parameters through testing in addition to spending time and costs requires laboratory equipment. Therefore, in this thesis, a three-dimensional finite element model with ABAQUS software was constructed to analyze the persistent pavement using theoretical relations without conducting the experiment. Also, viscoelastic behavior of common asphalt mixtures and time dependence of its responses at different temperatures can be modeled in ABAQUS software. After performing the shear stress test for different axial loads, different temperatures, with or without a single coil, they found that all parameters are temperature dependent and the coefficient of friction does not depend on the applied axial load. This new model improves the accuracy of the finite element model and its important role can be an analytic expression that includes all the variables that are effective in the problem.

Study of the influence of relay elements on the erosion process on the basis of GIS technology

Published on: 29th May, 2020

OCLC Number/Unique Identifier: 8609748943

Erosion has become widespread in the local climatic conditions of Azerbaijan. From this point of view, different types of erosion (washing, erosion, deflation, etc.) can often be found in many soil types formed in the territory of the republic. It should be taken into account that as a result of erosion, the top fertile layer of the soil is washed away and as a result, the soil is deprived of the humus layer. In the presented article, the effect of relief elements on the erosion processes occurring in the lands of Gadabay region was studied on the basis of GIS technologies.

Functional Electrical Stimulation (FES): Clinical successes and failures to date

Published on: 2nd November, 2018

OCLC Number/Unique Identifier: 7929240992

Non-invasive electrical stimulation in the form of neuromuscular electrical stimulation (NMES) and functional electrical stimulation (FES) has been documented as an optional assessment and treatment technology for decades. In contrast, translation of the robust clinical evidence supporting the effectiveness of FES’ enhancement of muscle force generation and adding to the recovery of motor control following damage to the brain appears limited. Furthermore, enabling many patients to regain locomotion ability though utilization of FES as a standard care option in rehabilitation medicine remains unmet. This perspective evolved over years of collaborative experience in clinical research, teaching, and patient care having a common goal of advancing patients’ rehabilitation outcomes. The clinical successes are supported by repeated evidence of FES utilization across the life span, from toddlers to elders, from hospitals’ critical care units to the home environment. The utilization include managing multiple deficits associated with the musculo-skeletal, neurological, cardio-pulmonary, or peripheral vascular systems. These successes were achieved in no small part because of the technological advancement leading to today’s wearable wireless FES systems that are being used throughout the continuum of rehabilitation care. However, failures to benefit from FES utilization are likewise numerous, collectively depriving most patients from using the technology to maximize their rehabilitation gains. The most critical failures are both clinical and technological. Whereas numerous barriers to NMES and FES utilization have been published, the focus of this perspective is on barriers not considered to date.

Anxiety and depression as an effect of birth order or being an only child: Results of an internet survey in Poland and Germany

Published on: 14th September, 2017

OCLC Number/Unique Identifier: 7317595908

Background: Various studies examined the effect of birth order. First born children show usually better cognitive performance than their later born siblings. Studies on emotional aspects yield heterogeneous results, sometimes in favour of first born, sometimes in favour of later born children. Studies comparing only-children with children with siblings are rare. Method: An internet survey was performed in 508 Polish and 500 German subjects. Only-children, first born, middle born and latest born children were compared regarding body mass index, depression, anxiety and partnership. Results: No differences among first born, middle born and latest born children were detected. Only-children reported significantly less symptoms of social phobia than first born children (z=0.50, p< 0.01). Conclusions: Except for suicidality, the results of this study question the sense of further investment in studying effects of birth order. In contrast, examining differences between only-children vs. children having siblings seems to have the potential to yield interesting and new results. Optimally, such research would combine self-report measures with reports from others, such as parents, teachers or clinicians.
