Published: April 2017

Hepatoid carcinomas are undifferentiated epithelial carcinomas that are pathologically similar to hepatocellular carcinoma, but occur in a variety of organs. Hepatoid carcinomas, as strictly defined, typically produce α‐fetoprotein. In addition, a standard effective chemotherapy regimen for hepatoid carcinoma has yet to be established. We present a case of advanced primary ovarian cancer that was pathologically similar to hepatoid carcinoma without staining for α‐fetoprotein or hepatocyte paraffin 1. The primary ovarian, metastatic, and recurrent tumors shared similar pathological characteristics. Fourth‐line chemotherapy with pegylated liposomal doxorubicin and bevacizumab was effective in treating the recurrent tumor, even though this disease had recurred three times.
Ultrasound diagnosis of intramural pregnancy
Authors: Liu Na‐na , Han Xue‐song , Guo Xi‐juan , Sun Li‐tao , Kong Xian‐chao
Published: April 2017

Intramural pregnancy is a rare type of ectopic pregnancy, where the gestational sac is implanted inside the myometrium instead of the endometrial and fallopian tubes. Preoperative diagnosis remains very difficult. Ultrasonic findings vary according to the anatomical location or duration of pregnancy. In this study, we summarized the ultrasonic characteristics of intramural pregnancy by assessing three cases. We also propose a set of ultrasonic characteristics to facilitate differential diagnosis between intramural pregnancy and other types of ectopic pregnancy.

Aim

The aim of this study was to report the pregnancy outcomes of women who received different doses of corticosteroid supplementation during labor and delivery.

Methods

We conducted a retrospective review of 102 pregnant women who received oral corticosteroid therapy, delivered at Osaka University Hospital, and were administered intravenous corticosteroid supplementation during labor and delivery. From January 2008 to May 2012, 47 women were administered a high dose of corticosteroids (HD group). From June 2012 to December 2016, 55 women were given a low dose of corticosteroids (LD group).

Results

There were no significant differences in the patient characteristics between the two groups. The most frequent disease was systemic lupus erythematosus (30/102; 29.4%). Most women used prednisolone for more than 1 year (91/102; 89.2%) and at a dose of more than 5 mg/day (88/102; 86.3%). The total intravenous dose of hydrocortisone during labor and delivery ± standard deviation was 233.5 ± 129.4 mg (HD group) and 143.4 ± 38.1 mg (LD group), exhibiting a significantly larger dose in the HD group. No patients suffered an adrenal deficiency and there were no significant differences in the hemodynamics. There were three cases of puerperal endometritis, two patients with hyperglycemia, and one wound infection in the HD group, whereas one case of puerperal endometritis in the LD group. There were no significant differences in the neonatal outcomes.

Conclusion

Pregnancy outcomes did not differ between the high and low doses of corticosteroid supplementation during labor and delivery.
Analysis of symbiotic Symbiodinium in scleractinian corals off Northwestern Kish Island, Persian Gulf
Authors: Mashini Amirhossein Gheitanchi , Fard Yazdani Mona , Ghavam Mostafavi Pargol , Shahhosseiny Mohammad Hassan
Published: April 2017

The genus Symbiodinium plays an essential role in the resistance and survival of reef‐building corals during temperature anomalies. Coral colonies inhabiting the Persian Gulf (PG) experience extended periods of different stresses. Kish Island is located in the harsh environment of the Northern PG with previously reported bleaching episodes. Samples of six coral species from Northwestern Kish Island were analysed by internal transcribed spacer 2 of ribosomal DNA to identify in hospite Symbiodinium populations. The results showed that lineage D of Symbiodinium was the most prevalent clade among different coral colonies, while clade C was only detected in symbiosis with a single coral species. However, the detected Symbiodinium subclades belonged to two host generalists. The predominance of the stress tolerant Symbiodinium trenchii and subclade C3 could suggest an acclimatization strategy to cope with the hostile environment of the PG.
On peacocks and lyrebirds: Australian options, Brownian bridges, and the average of submartingales
Authors: Ewald Christian‐Oliver , Yor Marc
Published: April 2017

We introduce a class of stochastic processes, which we refer to as lyrebirds. These extend a class of stochastic processes, which have recently been coined peacocks, but are more commonly known as processes that are increasing in the convex order. We show how these processes arise naturally in the context of Asian and Australian options and consider further applications, such as the arithmetic average of a Brownian bridge and the average of submartingales, including the case of Asian and Australian options where the underlying features constant elasticity of variance or is of Merton jump diffusion type.

Authors: Ertuğ Nurcan , Ulusoylu Özge , Bal Ayça , Özgür Hazal
Published: April 2017

This study was conducted to determine and compare the effectiveness of nature sounds and relaxation exercises for reducing preoperative anxiety. A repeated measures randomized controlled trial design was used. We divided 159 preoperative patients into three groups: nature sounds (n = 53), relaxation exercises (n = 53), and control groups (n = 53). We evaluated anxiety using the visual analog scale and state anxiety inventory scores immediately before, immediately after, and 30 min after interventions in nature sounds and relaxation exercises groups, and silent rest in the control. We found no differences between the measurement values in the intervention groups, but we did observe a difference between the intervention and control groups. The two interventions were similarly effective in reducing preoperative anxiety. These simple and low‐cost interventions can be used to reduce preoperative anxiety in surgical clinics.

Published: April 2017

Background

We previously reported a higher prevalence of nasal obstructive disorders (NOD) in pediatric patients with persistent allergic rhinitis (PER) not responding to medical treatment. The aim of this study was to determine the impact of NOD on quality of life (QoL) in this population.

Methods

Real‐life prospective study including 142 patients (41 children, 6‐11 years old and 101 adolescents, 12‐17 years old) with moderate and severe PER. After 2 months of medical treatment (intranasal steroids and antihistamines), patients were asked whether their symptoms had improved (yes/no) and classified accordingly in R, responders and NR, non‐responders. Nasal symptoms (visual analog scale, VAS), NOD (nasal endoscopy), and QoL (PRQLQ, AdolQRLQ) were also assessed.

Results

Sixty‐nine adolescents and 24 children were included in the NR group. NR presented worse QoL overall scores in adolescents (3.16±1.1 vs 1.63±0.99; P=.00001) and children (2.19±0.82 vs 1.51±0.77, P=.02). Medical treatment failure was associated with worse outcomes in QoL (adolescents OR: 1.6, P<.0001; children OR: 1.04, P=.036). Female adolescents presented worse QoL scores than males (3.19 vs 2.36, P=.001). The presence of obstructive septal deviation (OR: 1.02, P=.005), obstructive turbinate hyperplasia (OR: 1.03, P=.0006), and coexistence of both (OR=2.06, P=.001) was associated with worse QoL in adolescents. A strong and highly significant correlation was found between nasal symptoms VAS and QoL.

Conclusion

The presence of NOD, particularly in adolescents, is associated with poor QoL outcomes. Assessment of NOD in pediatric PER should be considered an essential approach to determine the response to treatment and its impact on patient's QoL.
Fiscal Reforms, Fiscal Rule, and Development Spending: How Indian States Have Performed?
Authors: Chakraborty Pinaki , Dash Bharatee Bhusana
Published: April 2017

In the last decade, fiscal rule was introduced to institutionalize rule‐based fiscal control in India by enacting Fiscal Responsibility Legislation by the Union and state governments. Using a 14 year data set from 2000–01 to 2013–14, spread across 14 major states, this paper examines the impacts of fiscal rule on fiscal balance. Our findings confirm that the introduction of fiscal rule resulted in reduction in fiscal imbalance. The paper also found that, to comply with the deficit targets set by the fiscal rule, states resorted to spending cuts, primarily the discretionary development expenditures.

In order to enhance vaccine uptake by the immune cells in vivo, molecular engineering approach was employed to construct a polymeric immunoglobulin G scaffold (PIGS) that incorporates multiple copies of an antigen and targets the Fc gamma receptors on antigen‐presenting cells. These self‐adjuvanting immunogens were tested in the context of dengue infection, for which there is currently no globally licensed vaccine yet. Thus, the consensus domain III sequence (cEDIII) of dengue glycoprotein E was incorporated into PIGS and expressed in both tobacco plants and Chinese Ovary Hamster cells. Purified mouse and human cEDIII‐PIGS were fractionated by HPLC into low and high molecular weight forms, corresponding to monomers, dimers and polymers. cEDIII‐PIGS were shown to retain important Fc receptor functions associated with immunoglobulins, including binding to C1q component of the complement and the low affinity Fcγ receptor II, as well as to macrophage cells in vitro. These molecules were shown to be immunogenic in mice, with or without an adjuvant, inducing a high level IgG antibody response which showed a neutralizing potential against the dengue virus serotype 2. The cEDIII‐PIGS also induced a significant cellular immune response, IFN‐γ production and polyfunctional T cells in both the CD4+ and CD8+ compartments. This proof‐of‐principle study shows that the potent antibody Fc‐mediated cellular functions can be harnessed to improve vaccine design, underscoring the potential of this technology to induce and modulate a broad‐ranging immune response.
Simulation–Extrapolation for Bias Correction with Exposure Uncertainty in Radiation Risk Analysis Utilizing Grouped Data
Authors: Misumi Munechika , Furukawa Kyoji , Cologne John B. , Cullings Harry M.
Published: April 2017

In observational epidemiological studies, the exposure that is received by an individual often cannot be precisely observed, resulting in measurement error, and a common approach to dealing with measurement error is regression calibration (RC). Use of RC, which requires assumptions about the distribution of unknown error-free (true) variables, leads to concern about the possibility of bias due to misspecification of that distribution. The simulation–extrapolation (SIMEX) method, in contrast, does not require a distributional assumption. However, analyses of large cohorts may be performed by using grouped or person-year data, and application of SIMEX to grouped data is not straightforward, particularly when there is a mixture of classical and Berkson measurement errors. We compared RC and SIMEX with grouped data analyses to assess robustness of the RC method to misspecification of the true dose distribution. We also applied SIMEX assuming mixtures of classical and Berkson errors and compared the results with those obtained by using RC for classical error only. SIMEX had less bias than RC and performed well regardless of the true dose distribution, whereas RC based on a misspecified true dose distribution showed greater bias than when based on the correctly specified true dose distribution.
Justice at the Margins: The Social Contract and the Challenge of Marginal Cases
Authors: Bauer Nathan , Svolba David
Published: April 2017

Attempts to justify the special moral status of human beings over other animals face a well‐known objection: the challenge of marginal cases. If we attempt to ground this special status in the unique rationality of humans, then it becomes difficult to see why nonrational humans (infants, the severely cognitively disabled, and so on) should be treated any differently than other, nonhuman animals. We respond to this challenge by turning to the social contract tradition. In particular, we identify an important role for the concept of recognition in attempts to secure rights through a social contract. Recognition, which involves identifying with or seeing ourselves as others, is the key to establishing the scope of justice, and we argue that this scope extends to all humans—even the so‐called marginal cases—but not to other animals. If this is correct, then we have a principled reason for why all humans have certain rights that other animals lack.

Published: April 2017

This study examined primary grades students’ achievement on number sense tasks administered through an Internet‐based formative assessment tool, Assessing Math Concepts Anywhere. Data were analyzed from 2,357 students in teachers’ classrooms who had participated in a year‐long professional development program on mathematics formative assessment, 1,427 students from teachers who had participated in the program in the year prior, and 9,783 students whose teachers had not participated at all. Analyses indicated that all students in the treatment group demonstrated growth, and that student achievement was influenced by the number of times the assessment was used to collect data and make instructional decisions. Further, there was a relationship between districts’ socioeconomic status and growth, meaning students from impoverished backgrounds grew more than their peers.

Published: April 2017

Among organ transplant recipients, cytomegalovirus (CMV) commonly results in various types of infection such as pneumonitis, hepatitis, and enterocolitis. However, CMV peritonitis is very rare and difficult to diagnose owing to lack of visible clinical signs. We present a case of a 35‐year‐old female kidney recipient who developed abdominal pain and urinary retention caused by CMV peritonitis. To our knowledge, this is the first case report of CMV peritonitis after organ transplantation to be diagnosed through histopathological examination.
Can the Lamberts and Lambert Submaximal Cycle Test Reflect Overreaching in Professional Cyclists?
Authors: Decroix Lieselot , Lamberts Robert P. , Meeusen Romain
Published: April 2017

Context: The Lamberts and Lambert Submaximal Cycle Test (LSCT) consists of 3 stages during which cyclists cycle for 6 min at 60%, 6 min at 80%, and 3 min at 90% of their maximal heart rate, followed by 1-min recovery. Purpose: To determine if the LSCT is able to reflect a state of functional overreaching in professional female cyclists during an 8-d training camp and the following recovery days. Methods: Six professional female cyclists performed an LSCT on days 1, 5, and 8 of the training camp and 3 d after the training camp. During each stage of the LSCT, power output and rating of perceived exertion (RPE) were determined. Training diaries and Profile of Mood States (POMS) were also completed. Results: At the middle and the end of the training camp, increased power output during the 2nd and 3rd stages of the LSCT was accompanied with increased RPE during these stages and/or the inability to reach 90% of maximal heart rate. All athletes reported increased feelings of fatigue and muscle soreness, while changes in energy balance, calculated from the POMS, were less indicative of a state of overreaching. After 3 d of recovery, all parameters of the LSCT returned to baseline, indicating a state of functional overreaching during the training camp. Conclusion: The LSCT is able to reflect a state of overreaching in elite professional female cyclists during an 8-d training camp and the following recovery days.
No Compromise of Competition Sleep Compared With Habitual Sleep in Elite Australian Footballers
Authors: Lalor Benita J. , Halson Shona L. , Tran Jacqueline , Kemp Justin G. , Cormack Stuart J.
Published: April 2017

Purpose: To assess the impact of match-start time and days relative to match compared with the habitual sleep characteristics of elite Australian Football (AF) players. Methods: 45 elite male AF players were assessed during the preseason (habitual) and across 4 home matches during the season. Players wore an activity monitor the night before (−1), night of (0), 1 night after (+1), and 2 nights (+2) after each match and completed a self-reported rating of sleep quality. A 2-way ANOVA with Tukey post hoc was used to determine differences in sleep characteristics between match-start times and days relative to the match. Two-way nested ANOVA was conducted to examine differences between competition and habitual phases. Effect size ± 90% confidence interval (ES ± 90% CI) was calculated to quantify the magnitude of pairwise differences. Results: Differences observed in sleep-onset latency (ES = 0.11 ± 0.16), sleep rating (ES = 0.08 ± 0.14), and sleep duration (ES = 0.08 ± 0.01) between competition and habitual periods were trivial. Sleep efficiency was almost certainly higher during competition than habitual, but this was not reflected in the subjective rating of sleep quality. Conclusions: Elite AF competition does not cause substantial disruption to sleep characteristics compared with habitual sleep. While match-start time has some impact on sleep variables, it appears that the match itself is more of a disruption than the start time. Subjective ratings of sleep from well-being questionnaires appear limited in their ability to accurately provide an indication of sleep quality.
Maximal Aerobic Power in Aging Men: Insights From a Record of 1-Hour Unaccompanied Cycling
Authors: Capelli Carlo
Published: April 2017

Purpose: To analyze best 1-h unaccompanied performances of master athletes in ages ranging from 35 to 105 y to estimate the decay of maximal aerobic power (MAP) across the spectrum of age. Methods: MAP at the various ages was estimated by computing the metabolic power () maintained to cover the distances during best 1-h unaccompanied performances established by master athletes of different classes of age and by assuming that they were able to maintain an equal to 88% of their MAP during 1 h of exhaustive exercise. Results: MAP started monotonically decreasing at 47 y of age. Thereafter, it showed an average rate of decrease of ∼14% for the decades up to 105 y of age, similar to other classes of master athletes. Conclusions: The results confirm, by extending the analysis to centennial subjects, that MAP seems to start declining from the middle of the 5th decade of age, with an average percentage decay that is faster than that traditionally reported, even when one maintains a very active lifestyle. The proposed approach may be applied to other types of human locomotion for which the relationship between speed and is known.

Published: April 2017

Osteoporosis is a systemic disease characterized by the increase of bone fragility and fracture risk. Postmenopausal female osteoporotic patients were randomized into three groups: balance and coordination, strengthening, and aerobic exercise. The exercise programs were performed for 12 weeks, 1 hr each day for 3 days of the week. Patients were followed-up for 12 weeks after the initial intervention. After the exercise program, patients continued their daily life activities and were called back to the clinic for additional testing after 12 weeks. Static and dynamic balance measurements and pain and life quality assessments were performed at enrollment, and at the 12th and 24th weeks. Significant improvements in both the Timed Up and Go test and Berg Balance Scale values at the 12th week were only observed in the balance-coordination group. There were statistically significant improvements in night and daytime pain visual analog scale scores at the 12th and 24th weeks in the strengthening exercise group. No patient experienced falling during the 24th week follow-up. The strengthening exercises were observed to be more effective in pain reduction, and balance and coordination exercises were found to be more effective in improvement of static and dynamic balance.
An Examination of Exercise-Induced Feeling States and Their Association With Future Participation in Physical Activity Among Older Adults
Authors: Brunet Jennifer , Guérin Eva , Speranzini Nicolas
Published: April 2017

Although exercise-induced feeling states may play a role in driving future behavior, their role in relation to older adults’ participation in physical activity (PA) has seldom been considered. The objectives of this study were to describe changes in older adults’ feeling states during exercise, and examine if levels of and changes in feeling states predicted their future participation in PA. Self-reported data on feeling states were collected from 82 older adults immediately before, during, and after a moderate-intensity exercise session, and on participation in PA 1 month later. Data were analyzed using latent growth modeling. Feelings of revitalization, positive engagement, and tranquility decreased during exercise, whereas feelings of physical exhaustion increased. Feelings of revitalization immediately before the exercise session predicted future participation in PA; changes in feeling states did not. This study does not provide empirical evidence that older adults’ exercise-induced feeling states predict their future participation in PA.

Published: April 2017

Background:

The Physical Activity Readiness Medical Examination (PARmed-X) for Pregnancy aims to facilitate the communication between the health care provider, the fitness professional and the pregnant woman. The purpose of the current study was to test the psychometric properties of the Brazilian Portuguese version of the PARmed-X for Pregnancy.

Methods:

Reliability and validity of psychometric properties of the Brazilian Portuguese version of the PARmed-X for Pregnancy were tested in 107 women recruited from the Hospital de Clínicas de Porto Alegre. Participants completed the first page of the instrument twice with a minimal interval of 1 week for test-retest reliability analysis. The absolute and relative contraindications to exercise on page 2 of the document were completed by the obstetrician.

Results:

Results indicated good evidence of construct validity. The isolated items in the PARmed-X document presented a large heterogeneity in kappa coefficients ranging from very low estimates to perfect estimates. The overall indication of prescription of physical activity, nonetheless, presented a good kappa coefficient of 0.749.

Conclusions:

The Brazilian Portuguese version of the PARmed-X for Pregnancy can be applied as a valid tool for medical screening by health care providers to help inform safe exercise prescription during pregnancy.

Published: April 2017

Background:

Whether the energy cost of vinyasa yoga meets the criteria for moderate-to-vigorous physical activity has not been established.

Purpose:

To compare energy expenditure during acute bouts of vinyasa yoga and 2 walking protocols.

Methods:

Participants (20 males, 18 females) performed 60-minute sessions of vinyasa yoga (YOGA), treadmill walking at a self-selected brisk pace (SELF), and treadmill walking at a pace that matched the heart rate of the YOGA session (HR-Match). Energy expenditure was assessed via indirect calorimetry.

Results:

Energy expenditure was significantly lower in YOGA compared with HR-Match (difference = 79.5 ± 44.3 kcal; P < .001) and SELF (difference = 51.7 ± 62.6 kcal; P < .001), but not in SELF compared with HR-Match (difference = 27.8 ± 72.6 kcal; P = .054). A similar pattern was observed for metabolic equivalents (HR-Match = 4.7 ± 0.8, SELF = 4.4 ± 0.7, YOGA = 3.6 ± 0.6; P < .001). Analyses using only the initial 45 minutes from each of the sessions, which excluded the restorative component of YOGA, showed energy expenditure was significantly lower in YOGA compared with HR-Match (difference = 68.0 ± 40.1 kcal; P < .001) but not compared with SELF (difference = 15.1 ± 48.7 kcal; P = .189).

Conclusions:

YOGA meets the criteria for moderate-intensity physical activity. Thus, YOGA may be a viable form of physical activity to achieve public health guidelines and to elicit health benefits.

Published: April 2017

Background:

The burden of depression among Hispanics/Latinos indicates the need to identify factors related to depressive symptoms. This paper examines the relationship of physical activity (PA) and sedentary behavior (SB) with depressive symptoms in Hispanic/Latinos.

Methods:

The Hispanic Community Health Study / Study of Latinos (HCHS/SOL) is a population-based, cohort study of Hispanic/Latinos in 4 United States metropolitan areas. Objectively measured PA was coded into: sedentary behavior (SB), light-intensity (LPA), moderate-intensity (MPA), and vigorous-intensity (VPA); and the Center for Epidemiological Studies Depression Scale-10 assessed depressive symptoms. Multiple regression analysis utilizing isotemporal substitution, adjusted for relevant covariates, examined PA as predictors of depressive symptoms.

Results:

Substitution of 1 hour of SB with VPA resulted in a significant decrease in depressive symptoms (β = –1.215, P = .021). Similar decreases were observed when VPA replaced LPA (β = –1.212, P = .021) and MPA (β = –1.50 P = .034). MPA and LPA were not associated with lower depressive symptoms.

Conclusions:

Previous research has focused on the relationship of MVPA on depressive symptoms. Our results suggest these constructs should be examined separately as they may have unique relationships with depressive symptoms. The association of SB with greater depressive symptoms confirms previous reports.

Published: April 2017

As the technology has developed, cloud computing which is a kind of Internet-based computing has widely spread. In terms of operating cloud system in remote locations, there exist some problems when the failure of cloud system occurs. In such cases, workers need to go to the remote locations and maintain the system. This paper considers stochastic models of a redundant cloud system in remote locations. The cloud system has active devices and standby devices. We derive the steady-state availability and discuss optimal policies which maximize it. Finally, numerical examples are given.

The high structural selectivity of this sorbent was explained by giving the results of DFT calculation of pyridine derivatives axial complexes with porphyrin Ni(II) complexes.
THE EFFECT OF WORK-FAMILY CONFLICT AND JOB INSECURITY ON INNOVATIVE BEHAVIOUR OF KOREAN WORKERS: THE MEDIATING ROLE OF ORGANISATIONAL COMMITMENT AND JOB SATISFACTION
Authors: CHOI SUK BONG , CUNDIFF NICOLE , KIM KIHWAN , AKHATIB SAJA NASSAR
Published: April 2017

South Korea is becoming an advanced economy based on continuous innovative organisational efforts. Job stressors have been identified in the literature as a major hindrance to many positive organisational behaviours. We predict that job insecurity and work–family conflict will have a negative effect on innovative behaviour with mediators of job satisfaction and organisational commitment. Results from structural equation models provided support for this study. From a practical perspective, the significant negative relationships between job stressors and innovative behaviour imply the need to reduce work–family conflict and feelings of job insecurity in Korean companies in order to foster innovation.
Effect of CNTs and Interfacial Defects on the Vibration of CNT-Based Hybrid Nanotubes
Authors: Xiao Y. , Wang C. Y. , Feng Y. T.
Published: April 2017

A hybrid nanotube (HNT) is fabricated by coating carbon nanotubes (CNTs) with a concentric coating layer. Vibration of the HNTs is of great interest due to its potential applications in nano-resonators, nanosensors/actuators and nanogenerators. In particular, it is expected that the super stiff but very light CNTs would largely up-shift the vibration frequency and improve the performance of the achieved nanodevices. On the other hand, the hybrid structures may lead to the defects at the CNT-coating layer interface, which would down-shift the frequency and impair the integrity of the HNT. This paper aims to examine these issues by using a multiple-beam model for the pristine HNTs and a finite element model for the defective ones. The frequencies are obtained for the first five modes of the HNTs reinforced by a single-wall or a multi-wall CNT. It was shown that the strengthening effect of the CNTs is substantial for the high frequency vibrations of the HNTs with a thin coating layer. In this case, the inverse effect of the interfacial defects can also be observed.
The Mechanical Behavior and Martensitic Transformation of Porous NiTi Alloys Based on Geometrical Reconstruction
Authors: Lu Xiaofeng , Wang Chaojie , Li Gang , Liu Yang , Zhu Xiaolei , Tu Shantung
Published: April 2017

The finite element analysis (FEA) of porous NiTi shape memory alloys (SMAs) remains a challenge due to irregularity and complexity of pore structure. In this paper, the real finite element model (FEM) is established based on the geometrical reconstruction. Through a SMA constitutive model, the mechanical behavior and stress-induced martensitic (SIM) phase transformation are analyzed with the real FEM. The results show that the stress–strain curve of FEA is in good agreement with the experimental curve and the calculation can reflect the mechanical behavior well in the compressive process. With the increase of load, the SIM first appears pore walls or weak parts of struts, then spreads to the center of matrix, and finally happens to most of matrix. When the slope of the stress–strain curve shows obvious changes, the SIM has happened in quite a part of matrix.
Biomechanical Assessment for Healing Progression of Fractured Long Bones: Numerical Investigations of Bending Stiffness and Resonant Frequency
Authors: Liu Zongchao , Chen Gongfa , Liang Peng , Zhang Jiqiao , Cui Fangsen , Xu Minglong
Published: April 2017

Though biomechanical methods have been proposed to assess the healing status of fractured bones for more than two decades, the effective stiffnesses obtained theoretically never match the experimentally measured results for the healing progression. This paper proposed a novel numerical model, the simulation results of which are able to reflect the experimental observations. The callus is divided into 10 regions with different material properties and the gap-narrowing process of the fracture is simulated with the variations of the material properties during the healing progression. The variations of the effective bending stiffness and resonant frequency with the healing progression have been obtained. The bending stiffness and resonant frequency squared of the fractured bone show a substantial creeping part during gradual narrowing of the fracture gap. They start to increase rapidly during bridging of the fracture gap by a bony callus. When the Young’s modulus in the callus region calcified last (i.e., Region 10) reaches 5% that of the reference intact bone, the bending stiffness and resonant frequency squared rise up to 90% those of the reference intact bone. After that they increase slowly and get flat; they become less sensitive to bone growth in the late healing stages. It is the first time that the simulation results demonstrate three distinct stages like in the experimentally measured results. These results imply that the variations of the bending stiffness and resonant frequency squared are not linearly correlated with the healing progression; however, their fast growing phase does indicate bony bridging of the callus.

Integrated SnO2 electrode with hierarchical nanosheets array structure growing on three-dimensional (3D) macroporous Ni foam substrates is successfully prepared via a facile and effective template-free route. The self-supported integrated electrode can be directly used as anode for lithium-ion batteries (LIBs) without adding any ancillary materials. As a result, such integrated electrode exhibits superior electrochemical performances. It maintains a high reversible discharge capacity of 1617.8[Formula: see text]mAh[Formula: see text][Formula: see text][Formula: see text]g[Formula: see text] and a high cycling stability of 829.2[Formula: see text]mAh[Formula: see text][Formula: see text][Formula: see text]g[Formula: see text] even after 500 cycles. The unique structural features with large areas, shorter transport path of ion and electron as well as robust mechanical strength are probably responsible for the enhanced performance.

Published: April 2017

Bus lane with intermittent priority (BLIP) is an innovative method to improve the reliability of bus services while promoting efficient usage of road resources. Vehicle-to-vehicle (V2V) communication is an advanced technology that can greatly enhance the vehicle mobility, improve traffic safety, and alleviate traffic jams. To explore the benefits of BLIP operation under a connected environment, this study proposed a three-lane cellular automata (CA) model under opening boundary condition. In particular, a mandatory BLIP lane-changing rule is developed to analyze special asymmetric lane-changing behaviors. To improve the simulation accuracy, a smaller cell size is used in the CA model. Through massive numerical simulations, the benefits and influences of BLIP are explored in this paper. They include impacts on neighborhood lanes such as traffic density increasing and average speed decreasing, lane-changing behaviors, lane usage, and the impacts of bus departure interval and clear distance on the road capacity of BLIP. Analysis of traffic flow characteristics of BLIP reveals that there is a strong relationship among bus departure interval, clear distance, and road capacity. Furthermore, setting conditions for deployment of BLIP under the V2V environment such as reasonable departure interval, clear distance, and traffic density are obtained.
A New Method to Identify Reservoirs in Tight Sandstones Based on the New Model of Transverse Relaxation Time and Relative Permeability
Authors: Guo Yuhang , Pan Baozhi , Zhang Lihua
Published: April 2017

Relative permeability and transverse relaxation time are both important physical parameters of rock physics. In this paper, a new transformation model between the transverse relaxation time and the wetting phase’s relative permeability is established. The data shows that the cores in the northwest of China have continuous fractal dimension characteristics, and great differences existed in the different pore size scales. Therefore, a piece-wise method is used to calculate the fractal dimension in our transformation model. The transformation results are found to be quite consistent with the relative permeability curve of the laboratory measurements. Based on this new model, we put forward a new method to identify reservoir in tight sandstone reservoir. We focus on the Well M in the northwestern China. Nuclear magnetic resonance (NMR) logging is used to obtain the point-by-point relative permeability curve. In addition, we identify the gas and water layers based on new T2-Kr model and the results showed our new method is feasible. In the case of the price of crude oil being low, this method can save time and reduce the cost.

Authors: Amaral Gabriela Queiroz , Mota Paulo
Published: April 2017

O Projeto Bandeira Científica é um dos mais antigos Projetos de Extensão da Faculdade de Medicina da Universidade de São Paulo (FMUSP), colaborando desde sua criação para o fortalecimento da Educação Médica. Originalmente fundado em 1957, o Projeto passou desde então por várias transformações, reconstruções e fases de maturação. Atualmente tem como foco atuar em áreas de vulnerabilidade em saúde, desenvolvendo não só atividades de assistência, como também de prevenção e promoção à saúde. Ao longo do tempo, foi se tornando cada vez mais multidisciplinar, contando com a participação de diversos cursos da USP ligados direta ou indiretamente à saúde, além de estabelecer parcerias com universidades locais situadas próximos as cidades visitadas a cada ano. Busca ser um espaço transformador, onde estabelecer o diálogo com gestores e prestadores de serviços, elaborar propostas de intervenção e ir ao encontro de uma população com suas peculiaridades, possam ser fatores que desenvolvam a um processo de reflexão crítica nos alunos sobre as condicionantes histórico-estruturais da saúde no Brasil.
The autistic spectrum treatment in Uberaba, Minas Gerais, Brazil: a Winnicottian analysis
Authors: Braga Nayara Gomes , Serralha Conceição Aparecida
Published: April 2017

Relato de pesquisa que investigou o contexto de tratamento do espectro autista na cidade de Uberaba (MG). Participaram do estudo seis representantes de instituições que tratam crianças autistas. Os resultados mostraram que o público-alvo das instituições envolve, em sua maioria, crianças especiais, e não foram observados métodos de tratamento e formação clínica e teórica específicos para atende-lo. Com base na teoria de Winnicott, entende-se que esse tratamento deve visar à retomada do processo de amadurecimento e, para tanto, é necessário ambiente propício, envolvendo a instituição e os pais, bem como formação específica e apoio governamental e social
The Sinthomatic thread in autism process
Authors: Souza Cirlana Rodrigues de
Published: April 2017

Com base na teoria psicanalítica de Jacques Lacan, este artigo aborda os impasses subjetivos instaurados no percurso de constituição subjetiva de uma criança em tratamento psicanalítico em vias de uma resolução autista e de suas tentativas de saber-fazer com a língua nesse percurso. Parto da seguinte pergunta: qual a função da língua insistente da criança em uma fala que não servia para ela se comunicar? Como hipótese, considero a tomada da língua, pela criança, como tentativa de saberfazer com seu sintoma conferindolhe um estatuto de sinthoma, de uma amarração sinthomática como o modo de resposta do sujeito em constituição perante o imperativo do real. Discuto a questão do psicodiagnóstico e sua relação com a constituição do sujeito e a estrutura psíquica não definida na infância. Enfatizo a dupla causação do sujeito e exploro a lógica borromeana no autismo, a partir da fala e da língua dessa criança
Learnings from schizophrenics on the institutional treatment of psychosis
Authors: Bialer Marina
Published: April 2017

Este artigo aborda alguns ensinamentos da clínica com esquizofrênicos para o tratamento institucional no que tange à importância da abertura à surpresa, da permeabilidade à diferença e à mudança em contraposição aos mecanismos de fobia institucional de medo do outro, de fechamento da significação e da lógica naracísica-paranoica. O texto se ancora no trabalho institucional desenvolvido por Jean Oury e suas elaborações a respeito da esquizofrenia para debater a importância da circulação discursiva na instituição
Paradoxos do diagnóstico psicanalítico nos autismos
Authors: Vorcaro Angela Maria Resende
Published: April 2017

Apresenta-se a constituição subjetiva tal como concebida por Freud e Lacan, por meio do desdobramento do nó borromea- no, na trama dos registros Real, Simbólico e Imaginário. As duas primeiras posições de cruzamento dos registros são detalhados para apresentar uma hipótese do atamento de tais registros nos autismos. Conclui-se apontando bases das operações clínicas do tratamento do autismo com os conceitos de construção e de ato em psicanálise.

Published: April 2017

Este artigo tem como objetivo identificar e apresentar argumentos mineralógicos e químicos que demonstrem a existência de níveis de bentonitas inseridos na Formação Irati, em afloramentos a leste da cidade de Aceguá, sul do Rio Grande do Sul. Tratam-se de níveis com pequena espessura (em média 4 cm) e grande extensão lateral, constituídos de argilitos maciços branco-acinzentados a esverdeados que, em campo, contrastam com os folhelhos que compõem a Formação Irati. As bentonitas da Formação Irati se caracterizam por serem compostas predominantemente por Ca-montmorilonita e formam a matriz fina da rocha, na qual se encontram dispersos cristais primários, ou magmáticos, com tamanho não superior a areia muito fina. Entre os principais minerais primários identificados e representativos do ambiente vulcânico explosivo, encontram‑se pseudomorfos de β-quartzo, sanidina, biotita, zircão, apatita e ilmenita, além de fragmentos de quartzo e feldspatos (splinters). Mais raramente, encontram-se fragmentos de meso e macrocharcoals dentro das camadas de bentonita, que contrastam com a maturidade e tipo de matéria orgânica não vegetal do folhelho Irati. Com base na geoquímica da rocha e na cristaloquímica da montmorilonita neoformada nos níveis de bentonita, infere-se sobre a natureza do vulcanismo precursor. Ambas as metodologias apontam que nesse período as cinzas vulcânicas que alcançaram a Bacia do Paraná originaram-se de vulcanismo com composição intermediária, em concordância com o que é conhecido sobre as manifestações da Província Vulcânica Choiyoi Inferior, sincrônica com a sedimentação da Formação Irati na Bacia do Paraná.
Responding to Wartime Sexual Violence: un Peacekeeping and the Protection Agenda
Authors: Hultman Lisa , Johansson Karin
Published: April 2017

Recent years have seen an increased emphasis on protection of civilians and the problem of sexual violence. The Security Council has adopted a number of resolutions towards improving the status of women in the realm of peace and security. However, we do not know if this translates into action by the Security Council in terms of deploying peacekeepers to respond to sexual violence. In this paper, we examine to what extent the prevalence of sexual violence increases the likelihood that the un chooses to deploy peacekeeping operations. In doing so, we acknowledge that sexual violence is an underreported phenomenon, about which the Security Council may not have perfect information. We explore this question by using data from the svac dataset in all intrastate armed conflicts, 1989–2009, which provides information about sexual violence as reported by three main agencies. We examine to what extent sexual violence, as reported by different agencies, is correlated with a higher likelihood that the un deploys a peacekeeping operation. Our findings suggest that reports of sexual violence on average increase the likelihood of a peacekeeping operation. However, depending on which of the sources we consider, we find contradictory findings for whether the un responds differently to sexual violence perpetrated by states and non-state actors respectively.
