Friction of Polymers Sliding on Smooth Surfaces
Virginio Quaglini,Paolo Dubini
Advances in Tribology , 2011, DOI: 10.1155/2011/178943
Abstract: Friction plots of polymers sliding on smooth metal surfaces are generally characterized by two regions of distinct dependency on the normal load, with low sensitivity at low stress levels followed by a sharp change in the rate of decrease of friction with increasing pressure at levels above the plastic flow limit of the polymer. A simplified model is proposed to describe this behavior which accounts for the effect of the normal load on the growth of the real contact area and the shear stress at the interface between the polymer and the mating surface. The model has a wide generality when expressed in terms of dimensionless variables, allowing to rationalize the friction behavior of different polymers within a single framework. 1. Introduction Sliding bearings incorporating self-lubricating polymers are today widely employed in several fields of engineering, including mechanical, structural, civil, and biomedical, for their ability to provide low friction without the need of external lubrication, their low cost, and minimum maintenance burden. In such bearings the sliding surface of the polymer element usually matches a partner surface made of steel or other hard metals, since polymers are known to be more effective, as concerns friction and wear performances, against a metal than when sliding against themselves [1]. To achieve correct design and selection of the bearings according to the intended service conditions, assessing the influence of operating parameters like normal load, temperature, and velocity on the coefficient of friction of the polymer is crucial. To this aim, both semiempirical laws and physically sound models involving a large number of parameters have been developed. The sliding behavior of polymers has been widely studied over the last 50 years, and a number of well-established models of friction are today available (a recent review is reported in Myshkin and Petrokovets [2]). Two main mechanisms are acknowledged to contribute to the friction force between a polymer pad and a metal surface: the shearing of the junctions formed by adhesion between the asperities of the contacting surfaces, and the dissipation of energy due to and the dissipation of energy due to plastic deformation and abrasion [1, 3, 4]: under high contact stresses the asperities of the harder material plough the softer one, and the resistance to ploughing further contributes to increase the frictional force [5]. However, it is generally accepted that at low and medium pressure levels ploughing of a polymer on smooth metal surfaces can be neglected [6–8], and
The BovMAS Consortium: identification of QTL for milk yield and milk protein percent on chromosome 14 in the Brown Swiss breed

Italian Journal of Animal Science , 2010, DOI: 10.4081/ijas.2005.2s.13
Abstract: Numerous studies have found a large number of QTL associated with productive and functional traits in the cattle genome. Several Countries have already established research programs aiming at identification and exploitation of QTLs in dairy cattle (Bovenhuis and Schrooten 2002). However, the published results are not directly exploitable for MAS, as commercial interests limit the information in the literature, and because marker-QTL phase is specific to each family.

Case Reports in Rheumatology , 2013, DOI: 10.1155/2013/409152
Abstract: Drug Rash Eosinophilia Systemic Symptoms (DRESS) syndrome is a systemic hypersensitivity reaction characterized by exfoliative dermatitis and maculopapular rash, lymphadenopathy, fever, eosinophilia, leukocytosis, and involvement of internal organs as liver, lung, heart, and kidney; the disorder starts within 2–6 weeks after taking a drug with an incidence that ranges from 1/1000 to 1/10000 exposures. Fatal cases are reported. The exact pathogenesis of DRESS syndrome is not completely understood, while it is reported that amoxicillin could trigger it in patients who are taking allopurinol, sulfasalazine, NSAIDs, carbamazepine, strontium ranelate, lisinopril, lansoprazole, and minocycline. Amoxicillin could act directly, inducing the reactivation of a viral infection (HHV 6 and EBV) with symptoms similar to DRESS syndrome or by reducing the patients’ ability to detoxify the body from substances chronically taken. We describe a case of a patient admitted to our hospital for a DRESS syndrome flared after amoxicilline intake during treatment with sulfasalazine; this combination can activate severe reactions often with an insidious onset that can mimic an infectious disease. 1. Case Report A 53-year-old woman, Caucasian, without history of drug intolerance, heavy smoker, affected by remote diagnosis of Lyme disease, previous removal of ovarian cyst, and gastroesophageal reflux, was diagnosed in another hospital as having a seronegative spondyloarthritis with anterior right uveitis. For this reason sulfasalazine was started until the dosage of 2 grams per day; after six weeks of treatment, amoxicillin/clavulanic acid was administered for the onset of sore throat, fever and laterocervical lymphadenopathy, and sulfasalazine suspended. After 3 days, she was admitted to our hospital for an acute diffuse and itchy rash with hemorrhagic vesicles on oral cavity, facial edema, and worsening of lymphadenopathy and fever. On admission mental status was normal, body temperature was 39.2°C, blood pressure was 130/80, and the heart and respiratory rates were, respectively, 115 beats and 22 acts per minute. Laboratory tests showed neutrophilic leukocytosis with mild eosinophilia (WBC: 12200/mmc, PMNn: 8580/mmc, and Eo: 690/mmc), AST: 106?IU/L (nv < 30?IU/L), ALT: 350 IU/L (nv < 30?IU/L), GGT: 1047?IU/L (nv 5–36?IU/L), alcaline phosphatase: 2959?IU/L (nv < 240?IU/L), total bilirubin: 2,71?mg/dL (nv < 1.0?mg/dL), C-reactive protein 112?mg/L, (nv < 5.0?mg/L), and ERS 103?mm/1 hour; serum creatinine, glucose, calcium, Na eK, TSH, total gamma globulins, IgG/A/M, K/Lambda chain
Monitoring Recreational Waters: How to Integrate Environmental Determinants  [PDF]

Abstract: Recreational waters are associated with a higher risk of disease for people engaged in activities that bring them into contact with these waters. The primary cause of contamination of recreational waters is fecal microorganisms, which may originate from various sources and involve several modulating factors, making it a complex public health and en- vironmental issue. Monitoring recreational water quality should include two key components: Microbial water testing and monitoring environmental determinants associated with higher risks of contamination. Conducting both activities provides the foundation for a comprehensive assessment according to risk and the actual level of fecal pollution and thus could promote good management actions to ensure safe water quality. Nevertheless, monitoring of environmental determinants is rarely fully integrated in monitoring programs and is also harder to achieve, especially when water pol- lution is mainly associated with nonpoint sources. In order to achieve identification and monitoring of environmental determinants associated with fecal contamination of recreational waters, some specific steps should be followed and some questions must be answered. The objective of this review article is to present current knowledge on this topic and to suggest and discuss recommendations. Potential sources of contamination and factors able to modulate them should be identified and measured after the geographical area influencing fecal contamination of recreational water has been delineated. Statistical models have been developed to identify the relative importance of these environmental characteristics on fecal pollution of recreational waters but they do not allow for a full comprehension of the exact processes leading to this pollution, thus other methods should also be used to better understand these processes.
Availability and accessibility of diabetes clinics on Trinidad: An analysis using proximity tools in a GIS environment  [PDF]

Health (Health) , 2013, DOI: 10.4236/health.2013.511A2006

Non-communicable diseases (NCDs), account for a growing number of deaths worldwide. The English-speaking Caribbean has the highest per capita burden of NCDs in the region of the Americas [1]. This paper presents an overview of availability and accessibility based on clinic hours and physician fulltime equivalents (FTE) on the island of Trinidad devoted to diabetes and wound care. The project integrates a Geographic Information System (GIS) with epidemiologic and bio-statistical data to provide a necessary spatial analysis not otherwise possible. It examines the island’s ability to effectively deliver treatment to residents with diabetes by providing a geographic perspective to data published on the internet by the Trinidad-Tobago Ministry of Health and the Central Statistical Office. Results indicate a significant regional variability in both numbers of physicians and office hours devoted to diabetes treatment.

Abstract: The clinical course of disease is progressive and prognosis is poor, with no therapeutic options other than lung transplantation currently available, yet. The aim of this report is to describe two further cases of this rare disease, reviewing CT, clinical and histological features.Idiopathic pleuroparenchymal fibroelastosis (IPPFE) is an entity characterized by pleural and subpleural parenchymal fibrosis. It is extremely rare (only 7 cases have been described in the literature to date) and was first described in 2004 by the Interstitial Lung Disease Program of the National Jewish Medical and Research Center of Denver [1].Actually between 1996 and 2001, 5 cases were registered as cryptogenic syndrome with significant chest symptoms, radiographic pleura-parenchymal abnormalities and fibroelastotic changes seen on surgical biopsy specimens, without any evidence of other connective tissue disease [1]. Marked apical pleural thickening associated with superior hilar retraction is present at chest X ray analysis, and High Resolution Computed Tomography (HRCT) shows pleural thickening, fibrosis, architectural distortion, traction bronchiectasis and honeycomb lung [2]. The clinical course of this affection is progressive and prognosis is poor, with no therapeutic options other than lung transplantation available.We here describe two additional cases of this rare disease.A sixty-eight-year-old man non-smoker, ex-fishmonger, living in the countryside, presented to our institution with a three years long non-productive cough. Nine years earlier, the patient had been treated for gastric cancer, with subsequent negative follow-up examinations. No clubbing or other respiratory signs were observed upon physical examination. Lung functional exams were as follows: FVC 2.74 L-78%; FEV1: 99% and DLco 67%. No O2-desaturation during the a 420 m walk test was observed and final pO2 saturation was 96mmHg. Serological examination did not identify any sign of collagen-vascular disorders. CT
Survivors’ Perspectives of Organizational Downsizing on Knowledge Sharing in a Downsized Environment  [PDF]
Patricia Michelle Hall
Open Journal of Leadership (OJL) , 2012, DOI: 10.4236/ojl.2012.14004
Abstract: Organizational workforce reductions can negatively affect a company’s ability to preserve its knowledge base. The problem researched in this study was the perceived effect of downsizing on knowledge sharing among surviving employees. The purpose of this study was to determine the perceived effect of downsizing on knowledge sharing. Survivors’ knowledge sharing behavior was examined in relation to 1) survivor syndrome, 2) attitude towards knowledge sharing, and 3) perceived loss of knowledge power. A quantitative correlation research design was used to investigate the relationship between downsizing and knowledge sharing. A web-based survey was used to collect data. The convenience sample consisted of 37 management employees in the Texas region of a management consultant organization. Three sets of variables were examined: 1) survivor syndrome and actual knowledge sharing behavior, 2) survivors’ attitudes toward knowledge sharing and actual knowledge sharing behavior, and 3) perceived loss of knowledge power and actual knowledge sharing behavior. Findings from a Spearman rank order correlation revealed a statistically significant positive correlation between perceived loss of knowledge power and actual knowledge sharing behavior. Understanding survivors’ reactions can assist with planning for future reductions, and lead to the development of training programs to counter the challenges.
Medications in Mexico: The Growth and Distribution of Pharmacies in Ciudad Juárez, Chihuahua, Mexico from 1996-2011  [PDF]

US pharmacies tend to be located at intersections of major cross streets throughout a city, while in the case of Mexican border cities pharmacies are clustered close to US-Mexico border crossings. Presumably this is due to the volume of US clients who frequent the pharmacies. Although the precise number of border crossings to purchase medications is unclear, it is thought to be significant. In the past, patient-based surveys were the primary source for information regarding US residents crossing the border into Mexico for prescription medications. The current study examines the distribution of pharmacies throughout Ciudad Juárez, Chihuahua, Mexico, recording the change in the number of pharmacies over a 15-year period and suggesting the scale of US residents who use Mexican pharmacies. Field research was conducted in 1996 and 2011. Maps showing the location of pharmacies for these two years indicate a clustering of pharmacies within one and one-half miles of the city’s two principal border-crossings between the United States and Mexico. Provider-based surveys revealed that the majority of patients who use pharmacies closest to the border were US residents.
