Marginal Fit Comparison of CAD/CAM Crowns Milled from Two Different Materials.

PURPOSE
To evaluate the marginal fit of CAD/CAM copings milled from hybrid ceramic (Vita Enamic) blocks and lithium disilicate (IPS e.max CAD) blocks, and to evaluate the effect of crystallization firing on the marginal fit of lithium disilicate copings.


MATERIALS AND METHODS
A standardized metal die with a 1-mm-wide shoulder finish line was imaged using the CEREC AC Bluecam. The coping was designed using CEREC 3 software. The design was used to fabricate 15 lithium disilicate and 15 hybrid ceramic copings. Design and milling were accomplished by one operator. The copings were seated on the metal die using a pressure clamp with a uniform pressure of 5.5 lbs. A Macroview Microscope (14×) was used for direct viewing of the marginal gap. Four areas were imaged on each coping (buccal, distal, lingual, mesial). Image analysis software was used to measure the marginal gaps in μm at 15 randomly selected points on each of the four surfaces. A total of 60 measurements were made per specimen. For lithium disilicate copings the measurements for marginal gap were made before and after crystallization firing. Data were analyzed using paired t-test and Kruskal-Wallis test.


RESULTS
The overall mean difference in marginal gap between the hybrid ceramic and crystallized lithium disilicate copings was statistically significant (p < 0.01). Greater mean marginal gaps were measured for crystallized lithium disilicate copings. The overall mean difference in marginal gap before and after firing (precrystallized and crystallized lithium disilicate copings) showed an average of 62 μm increase in marginal gap after firing. This difference was also significant (p < 0.01).


CONCLUSIONS
A significant difference exists in the marginal gap discrepancy when comparing hybrid ceramic and lithium disilicate CAD/CAM crowns. Also crystallization firing can result in a significant increase in the marginal gap of lithium disilicate CAD/CAM crowns.
CAPACITOR SWITCHING TRANSIENT MODELING AND ANALYSIS ON AN ELECTRICAL UTILITY DISTRIBUTION SYSTEM USING SIMULINK SOFTWARE

OF THESIS CAPACITOR SWITCHING TRANSIENT MODELING AND ANALYSIS ON AN ELECTRICAL UTILITY DISTRIBUTION SYSTEM USING SIMULINK SOFTWARE The quality of electric power has been a constant topic of study, mainly because inherent problems to it can bring great economic losses in industrial processes. Among the factors that affect power quality, those related to transients originated from capacitor bank switching in the primary distribution systems must be highlighted. In this thesis, the characteristics of the transients resulting from the switching of utility capacitor banks are analyzed, as well as factors that influence there intensities. A practical application of synchronous closing to reduce capacitor bank switching transients is presented. A model that represents a real distribution system 12.47kV from Shelbyville sub-station was built and simulated using MATLAB/SIMULINK software for purposes of this study. A spectral analysis of voltage and current waves is made to extract the acceptable capacitor switching times by observing the transient over-voltages and, harmonic components. An algorithm is developed for practical implementation of zero-crossing technique by taking the results obtained from the SIMULINK model.
Do open youth unemployment and youth programs leave the same mental health scars?--Evidence from a Swedish 27-year cohort study.

BACKGROUND
Recent findings suggest that the mental health costs of unemployment are related to both short- and long-term mental health scars. The main policy tools for dealing with young people at risk of labor market exclusion are Active Labor Market Policy programs for youths (youth programs). There has been little research on the potential effects of participation in youth programs on mental health and even less on whether participation in such programs alleviates the long-term mental health scarring caused by unemployment. This study compares exposure to open youth unemployment and exposure to youth program participation between ages 18 and 21 in relation to adult internalized mental health immediately after the end of the exposure period at age 21 and two decades later at age 43.


METHODS
The study uses a five wave Swedish 27-year prospective cohort study consisting of all graduates from compulsory school in an industrial town in Sweden initiated in 1981. Of the original 1083 participants 94.3% of those alive were still participating at the 27-year follow up. Exposure to open unemployment and youth programs were measured between ages 18-21. Mental health, indicated through an ordinal level three item composite index of internalized mental health symptoms (IMHS), was measured pre-exposure at age 16 and post exposure at ages 21 and 42. Ordinal regressions of internalized mental health at ages 21 and 43 were performed using the Polytomous Universal Model (PLUM). Models were controlled for pre-exposure internalized mental health as well as other available confounders.


RESULTS
Results show strong and significant relationships between exposure to open youth unemployment and IMHS at age 21 (OR = 2.48, CI = 1.57-3.60) as well as at age 43 (OR = 1.71, CI = 1.20-2.43). No such significant relationship is observed for exposure to youth programs at age 21 (OR = 0.95, CI = 0.72-1.26) or at age 43 (OR = 1.23, CI = 0.93-1.63).


CONCLUSIONS
A considered and consistent active labor market policy directed at youths could potentially reduce the short- and long-term mental health costs of youth unemployment.
Knowledge, attitude and practice of breast self-examination among female undergraduate students in the University of Buea

The incidence of breast cancer is on the rise in many parts of Africa. In Cameroon, there were an estimated 2625 cases per 100,000 in 2012. The awareness of breast cancer preventive methods is therefore critical in the reduction of breast cancer morbidity and mortality. This study evaluated the knowledge, attitude and practice of breast self-examination (BSE), among female undergraduate students in the University of Buea. The study comprised 166 female students of ages 17-30years (mean = 22.8 ± 3) sampled randomly. Data was collected by a pretested self-administered questionnaire. Nearly three quarter (73.5%) of the respondents had previously heard of BSE. Only 9.0% knew how to perform BSE. Similarly, only 13.9% knew what to look for while performing BSE. Television (19.9%) was the main source of information on BSE. Although perceived by 88% of the respondents as important, only 3% had performed BSE regularly. Furthermore, only 19.9% of the respondents have been to any health facility to have breast examination. Overall, although a majority (63.3%) of the respondents had a moderate attitude towards BSE as an important method for early detection of breast cancer, just a modest 9.6% were substantially aware of it. Lack of knowledge on BSE was cited as the main reason for not performing BSE. A significant association was observed between knowledge and the practice of BSE (P = 0.029), and between attitude and the practice of BSE (P = 0.015). These findings highlight the current knowledge gap that exists in the practice of BSE in the prevention of breast cancer in the study population. Sensitization campaigns and educational programmes ought to be intensified in order to address this issue.
Japanese spousal smoking study revisited: how a tobacco industry funded paper reached erroneous conclusions.

OBJECTIVES
To provide a participant's account of the development of a paper commissioned by the tobacco industry examining the reliability of self reported smoking status; to redress the distorted report of this Japanese spousal smoking study which evaluated the reliability and validity of self reported smoking status, and estimated confounding by diet and lifestyle factors.


DESIGN
Repeated interviews on smoking status and its verification by environmental and biological markers for environmental tobacco smoke (ETS) exposure.


SETTING
Urban wives in Osaka City and Sizuoka City, Japan


PARTICIPANTS
Semi-random sampling of 200 wives in each city. From the Osaka subjects, 100 non-smoking wives were selected for the validity study.


MAIN OUTCOME MEASURES
Kappa coefficient for reliability of self reported smoking status. Correlation coefficients between environmental nicotine concentration, cotinine in saliva and urine, and self reported smoking status.


RESULTS
The kappa coefficient for the repeated interview was high suggesting sufficient reliability of the response. The proportion of self reported current smokers misclassified as non-smokers was equivalent to the misclassified self reported non-smokers. Ambient concentration of nicotine and personal exposure to nicotine correlated with each other and also with salivary cotinine and self reported ETS exposure but not with urinary cotinine/creatinine ratio (CCR). There was no major difference in diet and lifestyle related to husband's smoking status.


CONCLUSION
Self reported smoking status by Japanese wives shows high reliability. It also shows high validity when verified by both nicotine exposure and salivary cotinine, but not by CCR. A previous report questioning the credibility of self reported smoking status, based on questionable CCR, could thus be of dubious validity. In addition, possible dietary and lifestyle confounding factors associated with smoking husbands were not demonstrable, a finding not reported previously. Using all the data from this project changes the conclusion of the previous published report. In addition to the distortion of scientific findings by a tobacco industry affiliated researcher, anti-smoking campaigners made attempts to intimidate and suppress scientific activities. These distortions of science should be counteracted.

1 Student, Assistant professor 1 Information Technology,SRM University, Kattankulathur-603203 ,India 2 Information technology,SRM University, Kattankulathur-603203 ,India sujayabhattacharjee09@gmail.com, yaashyaashuwanth@gmail.com ________________________________________________________________________________________________________ Abstract— The primary concern of “An Intelligent Agriculture Environment Monitoring System Using Autonomous Mobile Robot” is to monitoring the environmental condition of the agricultural field in real time. This project deals with creating a solution for such a situation in the form of a small robot that can do the task. The system uses several sensors that are mounted around the agricultural field and the signals are transferred to the robot using ZIGBEE transceivers so that it can detect the present environmental condition of fields and give information about the environment to the user through message. In this project we develop a smart wireless sensor network (WSN) for an agricultural environment, which can monitors the crop field’s environment for various factors such as temperature ,ph level, water level and humidity. Information about the environment are sent wirelessly to a Robot through ZIGBEE and Robot collects the data, stores it and sent the information to the User mobile using GSM module.
Rejuvenation of the Upper Face and Periocular Region: Combining Neuromodulator, Facial Filler, Laser, Light, and Energy-Based Therapies for Optimal Results.

BACKGROUND
The upper face and periocular region is a complex and dynamic part of the face. Successful rejuvenation requires a combination of minimally invasive modalities to fill dents and hollows, resurface rhytides, improve pigmentation, and smooth the mimetic muscles of the face without masking facial expression.


METHODS
Using review of the literature and clinical experience, the authors discuss our strategy for combining botulinum toxin, facial filler, ablative laser, intense pulsed light, microfocused ultrasound, and microneedle fractional radiofrequency to treat aesthetic problems of the upper face including brow ptosis, temple volume loss, A-frame deformity of the superior sulcus, and superficial and deep rhytides.


RESULTS
With attention to safety recommendations, injectable, light, laser, and energy-based treatments can be safely combined in experienced hands to provide enhanced outcomes in the rejuvenation of the upper face.


CONCLUSION
Providing multiple treatments in 1 session improves patient satisfaction by producing greater improvements in a shorter amount of time and with less overall downtime than would be necessary with multiple office visits.
Spectrum of e-business maturity in australian SMEs: a multiple case studies approach on the applicability of the stages of growth for e-business model

As a part of ongoing research to look at the pragmatic value of the stages of growth concept to map the progression of e-business maturity, this paper describes some of the empirical findings of a qualitative study into the progression and maturity of e-business in small and medium enterprises in Australia. In particular, the paper discusses the progression of ebusiness initiatives in three different companies at different levels of IS/IT maturity and the applicability of the stages concept in describing their progression. The cases presented in the paper clearly reveal that the IT managers and the CEO of the companies involved in the study responded favourably when using and applying the stages of growth for e-business (SOGe) model to their e-business experience and had no trouble in using the stages model to chart and identify the “evolution” of their e-business initiatives.

Long-term cost-effectiveness of home versus clinic-based management of chronic heart failure: the WHICH? study.

BACKGROUND
The cost-effectiveness of a heart failure management intervention can be further informed by incorporating the expected benefits and costs of future survival.


METHODS
This study compared the long-term costs per quality-adjusted life year (QALY) gained from home-based (HBI) vs specialist clinic-based intervention (CBI) among elderly patients (mean age = 71 years) with heart failure discharged home (mean intervention duration = 12 months). Cost-utility analysis was conducted from a government-funded health system perspective. A Markov cohort model was used to simulate disease progression over 15 years based on initial data from a randomized clinical trial (the WHICH? study). Time-dependent hazard functions were modeled using the Weibull function, and this was compared against an alternative model where the hazard was assumed to be constant over time. Deterministic and probabilistic sensitivity analyses were conducted to identify the key drivers of cost-effectiveness and quantify uncertainty in the results.


RESULTS
During the trial, mortality was the highest within 30 days of discharge and decreased thereafter in both groups, although the declining rate of mortality was slower in CBI than HBI. At 15 years (extrapolated), HBI was associated with slightly better health outcomes (mean of 0.59 QALYs gained) and mean additional costs of AU$13,876 per patient. The incremental cost-utility ratio and the incremental net monetary benefit (vs CBI) were AU$23,352 per QALY gained and AU$15,835, respectively. The uncertainty was driven by variability in the costs and probabilities of readmissions. Probabilistic sensitivity analysis showed HBI had a 68% probability of being cost-effective at a willingness-to-pay threshold of AU$50,000 per QALY.


CONCLUSION
Compared with CBI (outpatient specialized HF clinic-based intervention), HBI (home-based predominantly, but not exclusively) could potentially be cost-effective over the long-term in elderly patients with heart failure at a willingness-to-pay threshold of AU$50,000/QALY, albeit with large uncertainty.

Network QoS Management in Cyber-Physical Systems

Technical advances in ubiquitous sensing, embedded computing, and wireless communication are leading to a new generation of engineered systems called cyber-physical systems (CPS). CPS promises to transform the way we interact with the physical world just as the Internet transformed how we interact with one another. Before this vision becomes a reality, however, a large number of challenges have to be addressed. Network quality of service (QoS) management in this new realm is among those issues that deserve extensive research efforts. It is envisioned that wireless sensor/actuator networks (WSANs) will play an essential role in CPS. This paper examines the main characteristics of WSANs and the requirements of QoS provisioning in the context of cyber-physical computing. Several research topics and challenges are identified. As a sample solution, a feedback scheduling framework is proposed to tackle some of the identified challenges. A simple example is also presented that illustrates the effectiveness of the proposed solution.
Characterisation of Mediterranean Grape Pomace Seed and Skin Extracts: Polyphenolic Content and Antioxidant Activity

Grape pomace seeds and skins from different Mediterranean varieties (Grenache [GRE], Syrah [SYR], Carignan [CAR], Mourvèdre [MOU] and Alicante [ALI]) were extracted using water and water/ethanol 70% in order to develop edible extracts (an aqueous extract [EAQ] and a 70% hydro-alcoholic extract [EA70]) for potential use in nutraceutical or cosmetic formulations. In this study, global content (total polyphenols, total anthocyanins and total tannins), flavan-3-ols and anthocyanins were assessed using HPLC-UV-Fluo-MSn. In addition, extract potential was evaluated by four different assays: Oxygen Radical Absorbance Capacity (ORAC), Ferric Reducing Antioxidant Potential assay (FRAP), Trolox equivalent antioxidant capacity (TEAC) or ABTS assay and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. As expected, seed pomace extracts contained higher amounts of polyphenols then skin pomace extracts. Indeed, seeds from Syrah contained a particularly important amount of total polyphenols and tannins in both type of extract (up to 215.84 ± 1.47 mg of gallic acid equivalent [GAE]/g dry weight (DW) and 455.42 ± 1.84 mg/g DW, respectively). These extracts also expressed the highest antioxidant potential with every test. For skins, the maximum total phenolic was found in Alicante EAQ (196.71 ± 0.37 mg GAE/g DW) and in Syrah EA70 (224.92 ± 0.18 mg GAE/g DW). Results obtained in this article constitute a useful tool for the pre-selection of grape pomace seed and skin extracts for nutraceutical purposes.
Straddle injuries in female children and adolescents: 10-year accident and management analysis.

OBJECTIVE
To analyze unintentional straddle injuries in girls with regards to epidemiology, etiology and injury management.


METHODS
The hospital database was retrospectively reviewed (1999-2009) for female patients managed for genital trauma. Patients were evaluated based on age, causative factors, type of injury, area of genitals affected, management and outcomes.


RESULTS
Straddle injuries were documented in 91 girls with age ranging from 1 to 15 y (mean = 6.3 y; median = 6.1 y). The causes of injuries were falls at home (n = 31) or outdoors (n = 27), and sport activities (swimming pool n = 11, skating n = 11, bicycle n = 9 and scooter n = 2). Most of the injuries were lacerations. Injuries involved major labia (n = 56), minor labia (n = 45) and introitus vaginae (n = 15). Twelve children received outpatient treatment. Inspection under anesthesia was performed in 79 patients, with 76 requiring sutures. While hematuria was observed in 18 patients, cystoscopy did not reveal lesions in the urethra or bladder. Associated injuries were femur fracture (n = 1), lower extremity lacerations (n = 4) and anal lesions (n = 2). Follow-up investigations were uneventful; however one patient developed a secondary abscess and another secondary hyperplasia of the labia minor.


CONCLUSIONS
Falls and sports are major causes of straddle injuries with a peak at the age of six years. Lacerations are the most common injuries and often require surgical management. Urinary tract injuries and other associated injuries are relatively uncommon in girls with straddle injuries.
Checkpointing algorithms and fault prediction

This paper deals with the impact of fault prediction techniques on checkpointing strategies. We extend the classical first-order analysis of Young and Daly in the presence of a fault prediction system, characterized by its recall and its precision. In this framework, we provide an optimal algorithm to decide when to take predictions into account, and we derive the optimal value of the checkpointing period. These results allow to analytically assess the key parameters that impact the performance of fault predictors at very large scale.

Nous étendons l’analyse classique de Young en présence d’un système de prédiction de fautes, qui est caractérisé par son rappel (taux de pannes prévues sur nombre total de pannes) et par sa précision (taux de vraies pannes parmi le nombre total de pannes annoncées). Dans ce travail, nous avons pu obtenir la valeur optimale de la période de checkpoint (minimisant ainsi le gaspillage de l’utilisation des ressources dû au coût de prise de ces points de sauvegarde) dans différents scénarios.
