Optimization of cutting parameters for surface roughness in CNC turning machining with aluminum alloy 6061 material

Machining process involves many process parameters. Achieving accurate dimensions, good surface quality, and maximized metal removal are of utmost importance. This research work describes the optimization of cutting parameters for the surface roughness in CNC turning machining with aluminum alloy 6061 material. Controlling the required surface quality is necessary. In this study, Taguchi method is used to find the optimal cutting parameters for surface roughness in turning. L-9 orthogonal array, signal-to-noise ratio, and analysis of variance are employed to study the performance characteristics in the turning operations of aluminum alloy 6061 using uncoated inserts. A precise knowledge of these optimum parameters would facilitate reduction of machining costs and improve product quality. The current study on turning process applies a response surface methodology on the most effective process parameters, namely, feed, cutting speed, and depth of cut, which are optimized considering the surface roughness and material removal rate.
Fatal reactivation of hepatitis B post-chemotherapy for lymphoma in a hepatitis B surface antigen-negative, hepatitis B core antibody-positive patient: Potential implications for future prophylaxis recommendations

In the absence of prophylaxis, the reactivation of hepatitis B in oncology patients who are hepatitis B carriers is a well-known and often fatal complication of chemotherapy. The current recommendations in Canada and the USA are that patients who are positive for hepatitis B surface antigen (HBsAg) receive antiviral prophylaxis prior to chemotherapy. We report a 67-year-old man with B-cell lymphoma who developed hepatitis B reactivation following chemotherapy with cyclophosphamide, adriamycin, vincristine, prednisone and rituximab. Pre-chemotherapy, the patient was negative for HBsAg, positive for hepatitis B core antibody (anti-HBc) and weakly positive for hepatitis B surface antibody. Despite treatment with lamivudine, the patient died of fulminant hepatic failure. Our experience indicates that patients who are negative for HBsAg but positive for anti-HBc are still at risk for reactivation of latent hepatitis B during and after chemotherapy and may be considered for prophylaxis.
Patterns of remission, continuation and incidence of broadly defined eating disorders during early pregnancy in the Norwegian Mother and Child Cohort Study (MoBa)

ABSTRACT Background We explored the course of broadly defined eating disorders during pregnancy in the Norwegian Mother and Child Cohort Study (MoBa) at the Norwegian Institute of Public Health. Method A total of 41 157 pregnant women, enrolled at approximately 18 weeks' gestation, had valid data from the Norwegian Medical Birth Registry. We collected questionnaire-based diagnostic information on broadly defined anorexia nervosa (AN), and bulimia nervosa (BN), and eating disorders not otherwise specified (EDNOS). EDNOS subtypes included binge eating disorder (BED) and recurrent self-induced purging in the absence of binge eating (EDNOS-P). We explored rates of remission, continuation and incidence of BN, BED and EDNOS-P during pregnancy. Results Prepregnancy prevalence estimates were 0·1% for AN, 0·7% for BN, 3·5% for BED and 0·1% for EDNOS-P. During early pregnancy, estimates were 0·2% (BN), 4·8% (BED) and 0·1% (EDNOS-P). Proportions of individuals remitting during pregnancy were 78% (EDNOS-P), 40% (BN purging), 39% (BED), 34% (BN any type) and 29% (BN non-purging type). Additional individuals with BN achieved partial remission. Incident BN and EDNOS-P during pregnancy were rare. For BED, the incidence rate was 1·1 per 1000 person-weeks, equating to 711 new cases of BED during pregnancy. Incident BED was associated with indices of lower socio-economic status. Conclusions Pregnancy appears to be a catalyst for remission of some eating disorders but also a vulnerability window for the new onset of broadly defined BED, especially in economically disadvantaged individuals. Vigilance by health-care professionals for continuation and emergence of eating disorders in pregnancy is warranted.
14 Surface Electromyography During Both Standing and Walking in m . Ulnaris lateralis of Diversely Trained Horses Miss

The primary aim of any conditioning program in athletic horses is to improve performance by inducing physiological changes within the animal’s body, including limb muscles and tendons (Rivero, 2007). To this end, electromyography (EMG) has been used in human studies to determine muscle fitness and general muscle strength, but it also serves as an indicator of muscle injury and/or disease (Licka et al., 2009; Heaf et al., 2010). A good many studies have relied on needle electromyography (Tokuriki et al., 1989; Wijnberg et al., 2003a; Winjberg et al., 2003b), which in many ways is a precise technique, giving access to information about individual motor units within muscles, but this technique does not lend itself readily to muscles during periods of rapid and forceful contraction. Under such situations surface electromyography (sEMG) is preferred and in the equine, studies of primarily the back muscles have been undertaken (Licka et al., 2001; Licka et al., 2004; Peham et al. 2001), although sEMG has been used in ponies to identify forelimb muscle function (Jansen et al., 1992). Being a rapid, painless and non-invasive method of measuring muscle activity, surface electromyography (sEMG) is potentially useful in equine athletes. For horses competing in sports events, it is essential that their limbs remain healthy and sound. Indeed, lameness and training induced injuries of the forelimb have become increasingly more common in competition horses (Kohnke, 2004; Firth, 2006), mainly as a result of a raised athletic level and increasing numbers of horses participating in competitions. It is not surprising therefore that sEMG has already begun to be used to supplement clinical findings in injured horses, and is very often explored as an informative technique when other means of clinical examination fail (Wijnberg et al., 2004). Perhaps of greater importance, however, is the very real potential to use this technique as a measure of muscle efficiency during locomotion/exercise and in so doing, provide an insight into a horses muscle fitness and health at any given point in time, as well as enable a rider or owner to follow an individual animals response to training. sEMG reflects the force and degree of activity/coordination of a muscle during a gait cycle, revealing bursts of activity when a muscle is active (Robert et al., 1999; Butcher et al., 2009). Yet, despite this
The follow-up evaluation of electrocardiogram and arrhythmias in children with fulminant myocarditis.

BACKGROUND Fulminant myocarditis involves various serious arrhythmias that sometimes have lethal consequences. The purpose of the present study was to investigate the electrocardiogram findings, arrhythmogenicity and abnormalities of the cardiac conduction system in children with fulminant myocarditis. METHODS AND RESULTS Between 1999 and 2008, 7 consecutive patients (mean age: 7 years) who suffered from fulminant myocarditis were included in the study. A 12-lead electrocardiogram, Holter monitoring and signal-averaged electrocardiograms were performed and compared between the acute, convalescent, and recovery phases in the 4 surviving patients. Also, electrophysiologic assessment was carried out during the convalescent phase. Five out of 7 patients developed complete atrioventricular block, 3 developed ventricular tachycardia, 2 had cardiac arrest, 2 developed sinus tachycardia, 1 developed ventricular fibrillation, 1 had advanced atrioventricular block, and 1 developed sick sinus syndrome. Among the surviving patients, all arrhythmias resolved during the convalescent and remote phases. No atrial or ventricular arrhythmias were induced in any patients during the programmed stimulation study. In the convalescent phase, no arrhythmias could be induced and there were no signs of any conduction abnormalities on electrophysiological assessment. CONCLUSIONS Close follow-up should be performed to observe for the occurrence of any new arrhythmias and/or a decrease in cardiac function in children with fulminant myocarditis.
An object-oriented model for spatio-temporal synchronization of multimedia information

Proposes an extension to an earlier proposed temporal synchronization model, called OCPN. The new model allows one to specify spatial operations at the time of authoring the multimedia information. The authors present a mechanism to translate the model into an object-oriented environment. For this purpose the temporal operations are selected as objects. This scheme has many advantages over the existing object-oriented model since it requires fewer number of objects as well as do not limit the users to share the actual raw data. A polynomial time algorithm is proposed to translate the new OCPN into an object hierarchy. <<ETX>>

What Your Teacher Told You is True: Latin Verbs Have Four Principal Parts

We describe two different strategies for generating the morphology of Latin verbs. First, we hand-code default inheritance hierarchies in the KATR formalism, treating inflectional exponents as markings associated with the application of rules by which complex word forms are deduced from simpler roots or stems. The high degree of similarity among verbs of different conjugation classes allows us to formulate general rules; these general rules are, however, sometimes overridden by conjugation-specific rules. This approach allows linguists to gain an appreciation for the structure of verbs, gives teachers a foundation for organizing lessons in morphology, and provides students a technique for generating forms of any verb. Second, we start with a paradigm chart, then automatically remove common parts and redundant morphosyntactic property sets (columns), combine similar conjugations (rows), and generate the KATR theory that produces a complete table of forms for a set of lexemes. This second approach automatically determines principal parts (for Latin, we verify that there are four), groups inflection classes into super-classes, and builds full paradigm charts.
Using music and motion analysis to construct 3D animations and visualisations

Abstract This paper presents a study into music analysis, motion analysis and the integration of music and motion to form creative natural human motion in a virtual environment. Motion capture data is extracted to generate a motion library, this places the digital motion model at a fixed posture. The first step in this process is to configure the motion path curve for the database and calculate the possibility that two motions were sequential through the use of a computational algorithm. Every motion is then analysed for the next possible smooth movement to connect to, and at the same time, an interpolation method is used to create the transitions between motions to enable the digital motion models to move fluently. Lastly, a searching algorithm sifts for possible successive motions from the motion path curve according to the music tempo. It was concluded that the higher ratio of rescaling a transition, the lower the degree of natural motion.
Structure of covalently bonded glass-forming melts: A full partial-structure-factor analysis of liquid GeSe2.

The first full partial-structure-factor analysis of molten GeSe 2 is made using the method of isotopic substitution in neutron diffraction. It is shown that the melt comprises roughlyequal numbers of edge- and corner-sharing tetrahedra which give rise to a highly connected or network liquid. Concentration fluctuations extend over distances characteristic of the intermediate-range order, contrary to the results obtained from recently developed effective potentials for covalently bonded glass-forming melts
A QoS Routing Protocol Supporting Unidirectional Links in MANETs

Mobile Ad Hoc networks is a multi-hop temporary autonomous networks, completely consisting of mobile nodes. In such networks, traditional routing protocol cannot effectively function. Considering the characteristics of mobile Ad Hoc networks, QRULA which can support QoS controlled routing is given to satisfy the demands of Ad Hoc networks with unidirectional Links. This protocol fully considers the existing unidirectional network, uses the UpperTable between adjoining nodes to choose the route with the limitation of delays and bandwidths, the QRULA can perform well in the scenarios of mobile Ad Hoc networks with unidirectional links. The simulated performance of the QRULA is done and reported. The result shows that QRULA can not only work well in the environment of Ad Hoc networks with unidirectional Links, but also has the advantage in such aspects as route loads and package transmission rates.
Cardiovascular function alterations induced by acute paradoxical sleep deprivation in rats

Abstract Sleep loss has been implicated in triggering the hypertension. The goal of the present study was investigated the possible mechanisms underlying cardiovascular alterations after acute paradoxical sleep deprivation (PSD). Male Wistar rats were assigned in two experimental groups: (1) control and (2) PSD for 24 h using the modified single platform method. Paradoxical sleep deprived rats exhibited higher blood pressure, heart rate (HR) and impaired baroreceptor sensitivity. After pharmacological autonomic double blockade (propranolol and methylatropine administration), intrinsic heart rate was decreased after PSD. The PSD rats showed a reduction in the vagal tone without affecting sympathetic tone. Isoproterenol administration (0.001, 0.01 and 1 µg/kg) induced an increase in ΔHR responses in PSD group. Electrocardiographic analysis in response to β-adrenergic stimulation indicated that PSD contributed to ventricular cardiac arrhythmias. Our findings suggest that acute paradoxical sleep loss induce cardiovascular alterations, autonomic imbalance accompanied by impaired baroreflex sensitivity and increased arrhythmia susceptibility.
Effect of Substrate Temperature on the Ordered Phase Formation in Sm–Ni Thin Film Deposited on Cu(111) Underlayer

Sm<sub>17</sub>Ni<sub>83</sub> (at.%) alloy thin films are prepared on Cu underlayers hetero-epitaxially grown on MgO(111) single-crystal substrates by employing an ultra-high vacuum molecular beam epitaxy system. The substrate temperature is varied from 100 <sup>°</sup>C to 500 <sup>°</sup>C. The film growth behavior and the detailed resulting film structure are respectively investigated by in situ reflection high-energy electron diffraction and by a combination of out-of-plane and in-plane X-ray diffractions. With increasing the temperature up to 300 <sup>°</sup>C, formation of ordered SmNi<sub>5</sub> phase is recognized. The films deposited above 400 <sup>°</sup>C consist of only epitaxial SmNi<sub>5</sub> (0001) crystal, whereas the films deposited below the temperature include amorphous phase and/or a hexagonal ordered phase other than SmNi<sub>5</sub>. When the temperature is increased from 300 <sup>°</sup>C to 500 <sup>°</sup>C, the long-range order degree of SmNi<sub>5</sub> film increases from 0.60 to 0.97. SmNi<sub>5</sub> phase formation is enhanced with increasing the temperature.
Cooperative Communications with Network Coding for Wireless Uplink Channels

Future wireless systems are characterized by large user capacity, high speed, high reliability. Yet, inherent fading and interference of wireless communications render these design objectives challenging. As an efficient and inexpensive method to combat wireless fading, cooperative communications ([1], [2]) has recently attracted lots of research efforts and practical implementations. The principle of cooperative communications is illustrated in Figure 1. In wireless uplinks, two or more users sending messages to a common base station (BS) form partners to help each other on information transmission. When user 1 communicates to the BS, the relay (partner user 2) also receives the messages for the broadcasting property of the wireless medium. Therefore, the information messages from user 1 are transmitted to the BS through two fading paths: one direct path and one indirect path through relay (user 2). The potential gain provided by the relay includes coverage, cooperative diversity, and increased spectral efficiency [1], [2]. Compared to the traditional MIMO, cooperative communications are not subject to the limitations of antenna size, cost, hardware etc.
Circulating sclerostin levels and bone turnover in type 1 and type 2 diabetes.

CONTEXT Previous observations showed a condition of low bone turnover and decreased osteoblast activity in both type 1 and 2 diabetes mellitus (DM1 and DM2). Sclerostin is a secreted Wnt antagonist produced by osteocytes that regulates osteoblast activity and thus bone turnover. Its levels increase with age and are regulated by PTH. OBJECTIVES The aim of the present study was to evaluate circulating sclerostin levels in patients with DM1 or DM2 with normal renal function and to analyze its relationship with PTH, 25-hydroxyvitamin D, and bone turnover markers. DESIGN, AND SETTING: This was a cross-sectional study conducted at a clinical research center. PARTICIPANTS Forty DM2 and 43 DM1 patients were studied and compared with a reference control group (n = 83). RESULTS In the overall cohort, sclerostin levels were higher in males than in females and significantly increased with age in both genders. The positive correlation between sclerostin and age was maintained in DM1 but not in DM2 patients. Moreover, sclerostin levels were higher in DM2 than in controls or DM1 patients, and this difference persisted when adjustments were made for age and body mass index. Consistent with previous clinical and experimental observations, sclerostin was negatively associated with PTH in nondiabetic patients (r = -0.30; P < 0.01), independently of age and gender. Conversely, an opposite but nonsignificant trend between PTH and sclerostin was observed in both DM1 (r = 0.26; P = 0.09) and DM2 (r = 0.32; P = 0.07) cohorts. CONCLUSIONS These findings suggest that sclerostin is increased in DM2. Moreover, the transcriptional suppression of sclerostin production by PTH might be impaired in both DM1 and DM2.
Below normal pre-procedural cardiac troponin I levels are associated with an adverse prognosis after percutaneous coronary interventions.

AIMS To evaluate the prognostic implications of baseline cardiac troponin (cTn) values in the normal range in stable coronary artery disease (CAD) patients successfully treated with percutaneous coronary intervention (PCI). METHODS AND RESULTS We investigated the correlation between pre-procedural cTnI levels and major clinical adverse events at three years of follow-up in 1,063 consecutive stable CAD patients with normal baseline cTnI levels, successfully treated with PCI. Patients with pre-procedural cTnI levels in the upper tertile showed an increased long-term risk of overall death (HR 3.17, 95% CI: 1.62 to 6.21; p=0.0001), cardiac death (HR 5.09, 95% CI: 2.30 to 11.25; p=0.002), myocardial infarction (MI) (HR 2.34, 95% CI: 1.45 to 3.76; p=0.003) and target vessel failure (TVF) (HR 1.91, 95% CI: 1.28 to 2.84; p=0.006). Pre-procedural cTnI levels remained significantly correlated after adjustment for clinical and angiographic findings. Analysis of pre-PCI values eliminated any association of post-PCI values with prognosis. CONCLUSIONS In stable CAD patients successfully treated with PCI, pre-procedural cTnI levels, in the upper limits of the normal range, are associated with hard cardiac endpoints.
Descoberta Automática de Relações Não-Taxonômicas a Partir de Corpus em Língua Portuguesa

Ontology construction is a complex process composed by extraction tasks for domain concepts, as well as taxonomic and non-taxonomic relations among concepts. The extraction of non-taxonomic relations is the most neglected task, specially for Portuguese texts. Therefore, this paper presents a proposal for extracting non-taxonomic relations from Portuguese texts represented by a list of concepts and their contextual information extracted automatically by ExATOlp software tool.
Treatment of Waldenström's macroglobulinemia with rituximab.

PURPOSE Waldenström's macroglobulinemia (WM) is a low-grade lymphoplasmacytic lymphoma in which CD20 is usually expressed on tumor cells. There is evidence that patients with WM may benefit from treatment with the anti-CD20 monoclonal antibody rituximab. We performed a prospective phase II study to clearly define the activity of rituximab in patients with this disease. PATIENTS AND METHODS Twenty-seven patients with WM were treated with rituximab 375 mg/m(2) intravenously (IV) for 4 weeks. Three months after completion of rituximab, patients without evidence of progressive disease received repeat 4-week courses of this agent. All patients were symptomatic, their median age was 72 years, and 15 patients were previously untreated. RESULTS Twelve patients (44%; 95% confidence interval, 25.5% to 64.7%) achieved a partial response after treatment with rituximab. Median time to response was 3.3 months (range, 2.2 to 7.1 months). Responses occurred in six (40%) of 15 previously untreated patients and in six (50%) of 12 pretreated patients. Patients with a serum immunoglobulin M less than 40 g/L had a significantly higher response rate. The median time to progression for all patients was 16 months, and with a median follow-up of 15.7 months, nine of 12 responding patients remain free of progression. Treatment with rituximab was well tolerated, with approximately one fourth of patients experiencing some mild form of infusion-related toxicity, usually fever and chills. CONCLUSION Our prospective data indicate that rituximab is well tolerated and active in patients with WM. Previously untreated and pretreated patients seem to benefit equally. Repeat 4-week courses of rituximab may prolong the duration of response of the disease, but this observation requires confirmation in prospective, randomized trials. Furthermore, studies that will combine rituximab with chemotherapy may be relevant.
Density, Salinity, and Entry Depths of Municipal Wastewater in an Urban Lake

The depths of entry of municipal wastewater into receiving lakes importantly affects associated impacts on water quality. The plunging behavior of two negatively buoyant inflows that carry municipal waste, an urban tributary and an effluent discharge, in Onondaga Lake, NY, is characterized and quantified based on an integrated program of monitoring, density calculations, and modeling. In‐lake signatures of plunging from the two inflows are differentiated according to constituents in which each is enriched. Under common contemporary conditions, the summer averages of the fraction of the urban stream and effluent discharge inflows plunging to stratified depths is predicted, with a calibrated hydrodynamic model, to be approximately 0.7 and 0.35, respectively. Recent short‐term increases in salinity levels from construction site dewatering caused greater plunging of the effluent discharge and interfered with normal complete fall turnover in the lake.
