Effects of Voltage Quality on Induction Motors’ Efficient Energy Usage

Today, about 50% of electrical energy produced is used in electric drives. Electrical motors consume around 40% of total consumed electrical energy (Almeida et al., 2007) and of that thereof, induction motors account for 96% of energy consumption. Around 67% of this energy is used in induction motors with a rating below 75 kW and it can be shown that 85% of the energy losses are dissipated in these rating motors. Efficiency improvements of constant-speed drives, both constant-torque and variable-torque drives, is very important. It is usual that techniques for efficiency improvements of variable-torque drives are different from those of constant-speed and constant-torque applications. The latter is dealt with through optimization; it is very difficult to design and build a motor with high rating efficiency and rating power factor it has been shown (Fei et al., 1989) that higher efficiencies are associated with lower power factor. It is especially difficult to design and build a drive operating at high efficiency and power factor over an entire range of loads, say from 25 100% of rated load (PN), i.e. at partial load.
Complications associated with lateral fabellotibial suture surgery for cranial cruciate ligament injury in dogs: 363 cases (1997-2005).

OBJECTIVE To report the complication rate for a commonly performed procedure (lateral fabellotibial suture [LFS]) used in the treatment of dogs with cranial cruciate ligament (CCL) injury. DESIGN Retrospective case series. ANIMALS 305 dogs evaluated for 363 incidents of CCL injury from January 1997 through December 2005 and treated with LFS. PROCEDURES Medical records were reviewed for information on breed, sex, age, body weight, clinical history, duration of surgery and anesthesia, primary surgeon, percentage of ligament tear, condition of medial meniscus, unilateral versus bilateral disease, implant material, duration of follow-up, and perioperative and postoperative complications. RESULTS 363 LFS procedures met the criteria for inclusion in the study. Complications (n=65) were recorded for 63 of the 363 (17.4%) surgical procedures. Multiple complications developed in 2 dogs. In 26 (7.2%) dogs, a second surgery was required to manage the complications. Breed, side on which surgery was performed, implant material, percentage ligament tear, meniscal condition and treatment, bandage use, perioperative antimicrobial use, and experience of surgeon did not influence the complication rate. Factors significantly associated with a higher rate of complications were high body weight and young age of dog at the time of surgery. CONCLUSIONS AND CLINICAL RELEVANCE LFS is associated with a lower perioperative and postoperative complication rate than has been reported for other surgical procedures to repair CCL injury. Heavier and younger dogs had more complications. Complication rate must be considered when choosing a surgical treatment for dogs with CCL injury.
Increased Serum Type IV Collagen Peptide in Carbon Tetrachloride‐treated Rats

We developed a competitive enzyme immunoassay for serum type IV collagen peptide as a marker of fibrogenesis, and examined the relationship between serum type IV collagen peptide and hepatic disorder in CCI, treated rats. The rats were treated for 8 weeks and signs of liver damage began to appear from about week 2. With the progression of these signs to liver fibrosis, type IV collagen increased in the fibrous septa and especially in the perisinusoidal walls, where the increase was manifested as development of a real basement membrane beneath the sinusoidal endothelial cells. In CCI4‐treated rats, serum type IV collagen peptide significantly increased with the progression of liver fibrosis. When CCI4 administration was stopped, the collagen peptide rapidly decreased without any rebound rise. An intimate relationship was found between the production of serum type IV collagen peptide and liver prolyl hydroxylase activity and the amount of collagen deposited in the liver. These results suggest that serum type IV collagen peptide will be a uset ul biochemical marker for the early detection of fibrogenesis in the liver.
BlendForces: A Dynamic Framework for Facial Animation

In this paper we present a new paradigm for the generation and retargeting of facial animation. Like a vast majority of the approaches that have adressed these topics, our formalism is built on blendshapes. However, where prior works have generally encoded facial geometry using a low dimensional basis of these blendshapes, we propose to encode facial dynamics by looking at blendshapes as a basis of forces rather than a basis of shapes. We develop this idea into a dynamic model that naturally combines the blendshapes paradigm with physics‐based techniques for the simulation of deforming meshes. Because it escapes the linear span of the shape basis through time‐integration and physics‐inspired simulation, this approach has a wider expressive range than previous blendshape‐based methods. Its inherent physically‐based formulation also enables the simulation of more advanced physical interactions, such as collision responses on lip contacts.
Randomized prospective comparison of intraventricular methotrexate and thiotepa in patients with previously untreated neoplastic meningitis. Eastern Cooperative Oncology Group.

PURPOSE This prospective randomized cooperative group study was conducted in patients with neoplastic meningitis treated with intrathecal methotrexate or thiotepa to assess response rates and survival, prognostic factors, and the toxicity of these regimens. PATIENTS AND METHODS Fifty-nine adults with nonleukemic malignancies, performance status of 0 to 3, and positive CSF cytologies were assigned to receive intrathecal methotrexate (10 mg) or thiotepa (10 mg) twice weekly. Radiation, was administered to mass lesions and/or symptomatic sites and appropriate systemic therapy was given concomitantly. RESULTS Fifty-two patients were assessable. Most were female (79%), nonambulatory (77%), had been pretreated with radiation (52%) and chemotherapy (77%), and had evidence of systemic disease (65%). Most primary cancers were of the breast (48%), lung (23%), or lymphatics (19%). Treatment arms were well balanced, except that more patients randomized to methotrexate had breast cancer (61% v 33%) and were without evidence of systemic cancer (21% v 4%). No patient had important neurologic improvement with therapy, and 75% deteriorated neurologically within 8 weeks of initiating therapy. Survival ranged from 4 days to 110.5+ weeks. Median survival for patients receiving methotrexate was 15.9 weeks and 14.1 weeks for patients treated with thiotepa. Factors predictive of shorter survival included progressive systemic disease (P = .0005), poor performance status (P = .03), and significant cranial nerve palsies (P = .02). Although serious toxicities were similar, mucositis (P = .04) and neurologic complications (P = .008) were more common in patients who received methotrexate. CONCLUSION The efficacy and overall toxicities of intraventricular methotrexate and thiotepa seem similar and neither reverses fixed neurologic deficits. Early diagnosis and treatment and new therapeutic approaches are needed to improve the outcome for patients with neoplastic meningitis.
The Clenching-Grinding Spectrum and Fear Circuitry Disorders: Clinical Insights from the Neuroscience/Paleoanthropology Interface

Abstract This review discusses the clenching-grinding spectrum from the neuropsychiatric/neuroevolutionary perspective. In neuropsychiatry, signs of jaw clenching may be a useful objective marker for detecting or substantiating a self-report of current subjective emotional distress. Similarly, accelerated tooth wear may be an objective clinical sign for detecting, or substantiating, long-lasting anxiety. Clenching-grinding behaviors affect at least 8% of the population. We argue that during the early paleolithic environment of evolutionary adaptedness, jaw clenching was an adaptive trait because it rapidly strengthened the masseter and temporalis muscles, enabling a stronger, deeper and therefore more lethal bite in expectation of conflict (warfare) with conspecifics. Similarly, sharper incisors produced by teeth grinding may have served as weaponry during early human combat. We posit that alleles predisposing to fear-induced clenching-grinding were evolutionarily conserved in the human clade (lineage) since they remained adaptive for anatomically and mitochondrially modern humans (Homo sapiens) well into the mid-paleolithic. Clenching-grinding, sleep bruxism, myofacial pain, craniomaxillofacial musculoskeletal pain, temporomandibular disorders, oro-facial pain, and the fibromyalgia/chronic fatigue spectrum disorders are linked. A 2003 Cochrane meta-analysis concluded that dental procedures for the above spectrum disorders are not evidence based. There is a need for early detection of clenching-grinding in anxiety disorder clinics and for research into science-based interventions. Finally, research needs to examine the possible utility of incorporating physical signs into Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition posttraumatic stress disorder diagnostic criteria. One of the diagnostic criterion that may need to undergo a revision in Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition is Criterion D (persistent fear-circuitry activation not present before the trauma). Grinding-induced incisor wear, and clenching-induced palpable masseter tenderness may be examples of such objective physical signs of persistent fear-circuitry activation (posttraumatic stress disorder Criterion D).
The Heartrate Reaction to Acute Stress in Horned Passalus Beetles (Odontotaenius disjunctus) is Negatively Affected by a Naturally-Occurring Nematode Parasite

There are many events in the lives of insects where rapid, effective stress reactions are needed, including fighting conspecifics to defend territories, evading predators, and responding to wounds. A key element of the stress reaction is elevation of heartrate (HR), for enhancing distribution of blood (hemolymph) to body compartments. We conducted two experiments designed to improve understanding of the insect stress reaction and how it is influenced by parasitism in a common beetle species (Odontotaenius disjunctus). By non-destructively observing heartbeat frequency before, during and after applying a stressor (physical restraint) for 10 min, we sought to determine: (1) the exact timing of the cardiac stress reaction; (2) the magnitude of heartrate elevation during stress; and (3) if the physiological response is affected by a naturally-occurring nematode parasite, Chondronema passali. Restraint caused a dramatic increase in heartrate, though not immediately; maximum HR was reached after approximately 8 min. Average heartrate went from 65.5 beats/min to a maximum of 81.5 (24.5% increase) in adults raised in the lab (n = 19). Using wild-caught adults (n = 77), average heartrates went from 54.9 beats/min to 74.2 (35.5% increase). When restraint was removed, HR declined after ~5 min, and reached baseline 50 min later. The nematode parasite did not affect baseline heartrates in either experiment, but in one, it retarded the heartrate elevation during stress, and in the other, it reduced the overall magnitude of the elevation. While we acknowledge that our results are based on comparisons of beetles with naturally-occurring parasite infections, these results indicate this parasite causes a modest reduction in host cardiac output during acute stress conditions.
Effect of Extraction Media and Storage Time on the Elution of Monomers from Four Contemporary Resin Composite Materials

Introduction: The purpose of this study was to examine the effect of different extraction media, including culture media, as well as storage times on the elution of monomers from modern dental composites. Materials and Methods: Four contemporary composite materials were tested: (a) Clearfil Majesty Esthetic (Kuraray), (b) Esthet X (DENTSPLY), (c) Filtek Silorane (3M ESPE), and (d) Admira (Voco). Forty-eight specimens were made. The specimens were stored in 1 ml of (a) artificial saliva, (b) Dulbecco`s Modified Eagle Medium (DMEM), (c) DMEM plus 10% fetal bovine serum (FBS), and (d) ethanol 75%. The specimens were analyzed after 24 hours and after 1 week of storage. HPLC Liquid Chromatography was performed to analyze the extracted solutions. The statistical package SPSS 18 was used for the statistical analysis of the results. Results: All the materials tested released monomers that were consistent with the base composition of their resin matrix. Bisphenol-A (BPA) was detected in Clearfil Esthetic and EsthetX when ethanol 75% was used for storage. TEGDMA was released at a faster rate compared to the other monomers with most of the monomer eluted in the first 24 hours. The effect of storage solution and storage time on the elution of the same monomers varied between materials. Conclusions: There was a significant effect of time, storage solution, and material on the elution of the detectable unbound monomers. Unbound monomers were detected in culture media, which may lead to false-negative results in cytotoxicity tests of resin composite materials. BPA was detected in two of the tested materials.
Energy-Efficient Query Management Scheme for a Wireless Sensor Database System

Minimizing the communication overhead to reduce the energy consumption is an essential consideration in sensor network applications, and existing research has mostly concentrated on data aggregation and in-network processing. However, effective query management to optimize the query aggregation plan at the gateway side is also a significant approach to energy saving in practice. In this paper, we present a multiquery management framework to support historical and continuous queries, where the key idea is to reduce common tasks in a collection of queries through merging and aggregation, according to query region, attribute, time duration, and frequency, by executing the common subqueries only once. In this framework, we propose a query management scheme to support query partitioning, region aggregation and approximate processing, time partitioning and aggregation rules, multirate queries, and historical database. In order to validate the performance of our algorithm, a heuristic routing protocol is also described. The performance simulation results show that the overall energy consumption for forwarding and answering a collection of queries can be significantly reduced by applying our query management scheme. The advantages and disadvantages of the proposed scheme are discussed, together with open research issues.
Vaginal agenesis: Experience with sigmoid colon neovaginoplasty

Aim: Objective of this study is to report our experience with sigmoid vaginoplasty in adolescents. Materials and Methods: A retrospective study of children with vaginal atresia and Mayer–Rokitansky–Kuster–Hauser syndrome. The sigmoid segment was used for vaginoplasty in all the cases. Results: Eight children were studied over a period of 7 years. The postoperative complications were ileus in 2, mucosal prolapse of the neovagina in 1, and minor wound infection in 1 patient. Seven patients are on regular follow-up. All the neovaginas were patent and functional. One patient had unacceptable perineal appearance, that is, badly scarred perineum as a late complication. None of the patients had vaginal stenosis or excessive mucus discharge, during follow-up visits. Out of the 7 patients, 2 patients are sexually active and satisfied. Conclusions: Sigmoid vaginoplasty is a safe and acceptable procedure for vaginal agenesis with good cosmetic results and acceptable complications rate. Sigmoid colon vaginoplasty is the treatment of choice because of its large lumen, thick walls resistant to trauma, adequate secretion allowing lubrication, not necessitating prolonged dilatation, and short recovery time.
Addressing IT security in practice: Key responsibilities, competencies and implications on related bodies of knowledge

This paper examines the responsibilities and the required skills for Information Technology (IT) security professionals. Content analysis of relevant jobs postings helped identify four types of positions and the associated responsibilities and requisite skills. The identified skills were further analyzed to assess their consistency with the identified responsibilities. Finally, the Body of Knowledge (BOK) for three relevant disciplines (Information Systems, IT and Computer Science) are reviewed to assess the extent to which they cover knowledge needed to address IT security in organizations. Findings identify possible gaps in the BOK and areas for improvement.
A Multicommodity Network-Flow Problem with Side Constraints on Paths Solved by Column Generation

The multicommodity network-flow model concerns routing of a number of commodities through a capacitated network at minimal cost. In the basic model, it is assumed that for each commodity, the flow can be routed on any path connecting its origin and its destination. In telecommunication applications, where a commodity represents a communication pair, there are often additional time-delay or reliability requirements on paths that are used for routing. These requirements may vary by communication pair, represented by different priority classes. In this paper, we extend the basic multicommodity network-flow model to include such side constraints on paths. The extended problem is NP-hard with the constrained shortest-path problem as a special case. To solve the extended model, we use a column-generation approach, in which the solution is built up successively by path generation. The side constraints are efficiently handled in the path-generation subproblem. We further discuss various enhancements of this approach. Computational results show that the column-generation approach provides an efficient way for solving the extended model, even for fairly large networks.
The Impact of Job Characteristics on Burnout ; The Mediating Role of Work Family Conflict and the Moderating Role of Job Satisfaction

The aim of this study is to test the relationships among job characteristics (skill variety, task significance, task identity, autonomy and feedback), job satisfaction, work family conflict (WFC) and burnout (exhaustion, personal accomplishment and cynicism). Various sets of factors including organizational characteristics, job characteristics, and individual characteristics are investigated in order to find out the root causes of job burnout. However, different from other studies, we investigated the mediating role of work family conflict and the moderating role of job satisfaction in explaining the relationship between job characteristics and burnout. The proposed hypotheses were tested by hierarchical regression analysis by means of data from 161 employees. The results indicated that WFC partially mediated the relationship between job characteristics and burnout.In addition, job satisfaction was found to moderate the relationship between job characteristics and burnout in such a way that the relationship is weaker for employees with high levels of job satisfaction. These empirical findings have important implications for human resource managers and organizational behavior researchers who are interested in how to reduce burnout that is likely to reduce the organization’s productivity and threaten its competitiveness in the long run.
Physical activity and obesity in children with congenital cardiac disease

Abstract Background Children with congenital cardiac disease experience challenges in developing healthy patterns of physical activity due to decreased exercise capacity and parental fear and confusion about what is permissible. The purpose of this study was to describe physical activity habits in children 10–14 years of age with congenital cardiac disease and the relationship of those habits to obesity as defined by body mass index. Methods This cross-sectional study used self-report measures and clinical data to describe the association between physical activity participation and body mass index in 10- to 14-year-old children with congenital cardiac disease. Further, physical activity levels were compared between children who were overweight or obese and those who were not. Results Children (n = 84; 51 males; 33 females) reported low rates of physical activity compared to reports on healthy children. Only 9.5% were overweight (body mass index between the 85th and 94th percentile), and alarmingly 26% were obese (body mass index at or above the 95th percentile). Physical activity and body mass index were not significantly correlated (r = −0.11, p = 0.45) and there was no significant difference in mean physical activity (t = 0.67) between children who were overweight or obese and those who were not. Conclusions Children in this study reported low rates of physical activity and a higher obesity rate than was reported in previous studies. However, the two were not significantly correlated. Further research is indicated to determine the specific factors contributing to obesity and to test interventions to combat obesity in children with congenital cardiac disease.
fMRI for Preoperative Neurosurgical Mapping of Motor Cortex and Language in a Clinical Setting

Purpose Identification of the precentral gyrus can be difficult in patients with brain tumors. The purpose of the current study was to evaluate the clinical usefulness of functional MRI (fMRI) in identifying motor cortex and speech areas as a part of preoperative neurosurgical planning. Method fMRI was performed using a 1.5 T MR unit in 41 patients with brain tumors. The motor paradigm was finger tapping and foot movement, whereas the language paradigm consisted of a two word semantic test. Statistical analysis of the data was done using the Kolmogorow-Smirnow test. Plots of signal intensities over time were created. Results The precentral gyrus was identified in 38 of 41 patients. In two patients, fMRI was not of acceptable quality due to motion artifacts. Speech areas were localized in 33 patients. In a typical clinical setting, the value of the method was graded “high. ” Conclusion fMRI`s efficacy in the preoperative localization of language and motor areas is high. The method should become a routine adjunct for preoperative evaluation of brain tumors in the near future.
