Adaptation of Social Interaction Learning Styles by Freshman Engineering Students in Communication Courses

D ue to the ever-changing nature of technology, it is no longer argued whether or not engineers need to brush up on their skills and/or take up new ones as they practice in the field. Engineering departments at universities, therefore, have felt obliged to make adjustments to their curriculum to meet the needs of societies for engineers with up-to-date technical knowledge. However, it is accepted that technical knowledge per se is not sufficient to be successful engineers. They will also need to acquire soft/professional skills, which include an ethical orientation and certain communication skills.
Cystic mesenchymal hamartoma mimicking hepatic hydatid disease.

Hydatid disease, caused by Echinococcus granulosus, is relatively rare in children. It is often described as having a pathognomonic appearance on ultrasound (US) and computed tomography (CT) [1]. Mesenchymal hamartoma is a rare hepatic developmental abnormality con®ned almost exclusively to children under the age of 2 years. After haemangioma it is considered to be the second commonest benign liver tumour in the paediatric age group, with 140 cases reported up to 1990 [2]. We report a case of cystic mesenchymal hamartoma in a 7-year-old girl which was radiologically indistinguishable from hepatic hydatid disease.
Optimising Delay Based Congestion Control for Geostationary Satellite Networks

Delay based congestion control algorithms have been shown to outperform their loss based counterparts, especially when used over wireless links. However, high latency wireless links such as those provided by geostationary satellite, still pose a number of performance problems for delay based congestion control. In this paper we analyse existing congestion control algorithms for both loss and delay based TCP variants, before presenting an optimised delay based congestion control model. Furthermore, we show that it is easier to model and optimise delay based congestion control, than a loss based system
Monitoring Socioeconomic Inequalities in Sexually Transmitted Infections, Tuberculosis, and Violence: Geocoding and Choice of Area-Based Socioeconomic Measures—The Public Health Disparities Geocoding Project (US)

Objectives. To determine which area-based socioeconomic measures, at which level of geography, are suitable for monitoring socioeconomic inequalities in sexually transmitted infections (STIs), tuberculosis (TB), and violence in the United States. Methods. Cross-sectional analysis of public health surveillance data, geocoded and linked to area-based socioeconomic measures generated from 1990 census tract, block group, and ZIP Code data. We included all incident cases among residents of either Massachusetts (MA; 1990 population = 6,016,425) or Rhode Island (RI; 1990 population = 1,003,464) for: STIs (MA: 1994–1998, n = 26,535 chlamydia, 7,464 gonorrhea, 2,619 syphilis; RI: 1994–1996, n = 4,473 chlamydia, 1,256 gonorrhea, 305 syphilis); TB (MA: 1993–1998, n = 1,793; RI: 1985–1994, n = 576), and non-fatal weapons related injuries (MA: 1995–1997, n = 6,628). Results. Analyses indicated that: (a) block group and tract socioeconomic measures performed similarly within and across both states, with results more variable for the ZIP Code level measures; (b) measures of economic deprivation consistently detected the steepest socioeconomic gradients, considered across all outcomes (incidence rate ratios on the order of 10 or higher for syphilis, gonorrhea, and non-fatal intentional weapons-related injuries, and 7 or higher for chlamydia and TB); and (c) results were similar for categories generated by quintiles and by a priori categorical cut-points. Conclusions. Supplementing U.S. public health surveillance systems with census tract or block group area-based socioeconomic measures of economic deprivation could greatly enhance monitoring and analysis of social inequalities in health in the United States.

Mycotoxins as a risk in the grain food

Mycotoxins are toxic secondary metabolites of fungi that contaminate a large variety of foods and have toxic effects on humans. The best protection against mycotoxins is to monitor their presence in food. This paper shows the screening results of mycotoxins present in 76 samples of different groups of grain foods. Samples of grain food were analyzed for contamination with aflatoxins, ochratoxin A, zearalenone, fumonisins and deoxynivalenol. Analysis were conducted using competitive enzyme-linked immunosorbent assay (ELISA). None of the samples was contaminated with aflatoxins. The most predominant mycotoxin was ochratoxin A with the mean level of 4.84 ± 4.49 ppb in 19.7% of the examined samples. Zearalenone, fumonisins, and deoxynivalenol were found in 9.21, 14.5 and 3.9% of the samples, respectively. Mycotoxin content in the investigated samples was compared with the regulations of Serbia and those of the European Union.
Low-Temperature, Solution-Processed, 3-D Complementary Organic FETs on Flexible Substrate

Vertical stacking of thin-film transistors is an effective way to reduce the footprint of a device, thus increases transistor density in complex flexible electronic applications without reducing the feature size and resolution of the patterning tools. In this paper, we report a 3-D complementary organic FET fabricated on a plastic substrate by stacking a bottom-gate top-contact p-type transistor on a top-gate bottom-contact n-type transistor with a gate shared between the two. We used high-performance polymer semiconductors, poly [(E)-2, 7-bis (2 decyltetradecyl) 4 methyl 9 (5 (2 (5 methylthiophen 2 yl) vinyl) thiophen 2 yl) benzo [lmn] [3, 8] phenanthroline-1, 3, 6, 8 (2H, 7H)-tetraone] for n-type devices and poly [2, 5-bis (7-decylnonadecyl) pyrrolo [3, 4-c] pyrrole-1, 4 (2H, 5H)-dione-(E) 1,2 bis (5 (thiophen 2 yl) selenophen 2 yl) ethene] for p-type devices to fabricate the vertically stacked organic transistors along with a Cytop and cross-linked poly (4-vinylphenol) bilayer and Poly (Methyl Methacrylate) gate dielectric. A 3-D flexible complementary organic inverter exhibits a maximum static voltage gain of <inline-formula> <tex-math notation="LaTeX">$\thickapprox 18$ </tex-math></inline-formula> V/V and high noise immunity of up to 60% of <inline-formula> <tex-math notation="LaTeX">${V} _{\mathrm {DD}}$ </tex-math></inline-formula>/2. The 3-D transistors show hysteresis-free <inline-formula> <tex-math notation="LaTeX">$I$ </tex-math></inline-formula>–<inline-formula> <tex-math notation="LaTeX">$V$ </tex-math></inline-formula> characteristics despite of low-temperature processes.

An Assessment of Computer-assisted learning in Orthodontics

Programs developed in BASIC for the Apple II permit the presentation of orthodontic case histories in an interactive way. Clinical observation and decisions may be monitored by multiple choice questions and marked to provide a final score. In comparisons between a CAL program and traditional tutorial teaching, 60 dental undergraduates obtained higher average scores after CAL. It is concluded that the CAL presentation of orthodontics clinical data is an effective and popular addition to traditional teaching.
Cluster-based adaptive fuzzy switching median filter for universal impulse noise reduction

In this paper, we present a novel method for the removal of impulse noise from digital images. The proposed filter, called the Cluster-based Adaptive Fuzzy Switching Median (CAFSM), is composed of a cascaded easy-to- implement impulse detector and a detail preserving noise filter. Initially, the impulse detector classifies any possible impulsive noise pixels. Subsequently, the filtering phase replaces the detected noise pixels. In addition, the filtering phase employs fuzzy reasoning to deal with uncertainties present in local information. Contrary to many existing filters that only focus on a particular impulse noise model, the CAFSM filter is capable of filtering all kinds of impulse noise - the random-valued and/or fixed-valued impulse noise models. Extensive simulations conducted on 100 monochrome images under a wide range of noise densities show that the CAFSM filter substantially outperforms other state-of-the-art impulse noise filters. Furthermore, the relatively fast processing time suggests the CAFSM filter's applicability in consumer electronic products such as digital cameras.
Serological Testing for Avian Influenza Viruses in Wild Birds : Comparison of Two Commercial Competition ELISAs

18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 Serologic testing of wild birds for AIV surveillance poses problems due to species differences and non-specific inhibitors that may be present in sera of wild birds. Recently available competitive ELISA kits offer a new species independent approach. In this study we compare two commercial cELISAs, using a total of 184 serum and plasma samples from 23 species of wild birds belonging to 10 orders. Thirteen samples were from experimentally HPAI and LPAI infected red-legged partridges (Alectoris rufa), 77 samples were from a flock of sentinel hybrid ducks confirmed infected by AI by RTPCR and 94 samples were from wild birds admitted to a rehabilitation center. Both ELISAs detected AI antibodies in the experimentally infected partridges, while HI was negative. Concordance in results between the two ELISAS was 51.5%. When specific subtype H5/H7 HI positive samples were considered for comparison, ELISA 1 appeared to perform better on ducks while ELISA2 appeared to perform better in other wild bird species. Overall, 68.2% of H5/H7 positive samples tested positive by ELISA 1 and 36% by ELISA 2. Both ELISAs detected AIV antibody positive samples negative by specific HI against 9 of the 16 existing HA subtypes. Presumably this reflects either higher sensitivity of cELISA when compared to HI, presence of antibodies against HA subtypes not tested, or unspecific reactions. Performance of ELISA 1 on ducks appears to be comparable to in-house cELISA previously used by other authors in wild birds but requires a relatively large sample volume. Alternatively, while the ELISA 2 required a smaller sample volume, it was less effective at identifying HI positive samples. The results reflect the necessity of validation of cELISA tests for individual species or at least families as required by the OIE.
Slow-release caffeine: a new response to the effects of a limited sleep deprivation.

STUDY OBJECTIVES The aim of this study is to assess the interest of the intake of a new galenic form of caffeine called "slow-release" caffeine (SR caffeine) during a decrease of vigilance due to a limited sleep deprivation. DESIGN The controlled method used compared three doses of SR caffeine (150, 300 and 600 mg) with a placebo. Tests were performed 2, 9 and 13 hours after each treatment. Wakefulness level was assessed subjectively through questionnaires and analog visual scales, and objectively with the Multiple Sleep Latency Test. Performance level was also assessed regularly with an attention test, a grammatical reasoning test, a spatial recognition test, a mathematical processing test, a visual tracking test, a memory search test, and a dual task. The motor activity was evaluated by wrist actimeter and safety of treatment was observed by regular clinical examination. SETTING NA. PARTICIPANTS Twenty-four young and healthy volunteers (12 men and 12 women) participated in a 32-hour sleep deprivation. INTERVENTIONS NA. RESULTS The results show a significant effect of slow-release caffeine vs. placebo, and on vigilance and performance when subjects became tired. The effects of SR caffeine lasted 13 hours after treatment. SR caffeine 300 and 600 mg are efficacious doses but the optimal dose (maximum effect without any side effects) for both men and women is after all 300 mg. Globally, there is no difference between placebo and caffeine during the recovery night period. CONCLUSIONS SR caffeine (300 mg) seems to be an efficient and safety substance to maintain a good level of vigilance and performance during limited sleep deprivation.
Quantitative Analysis of Wheat Proteins in Different Varieties Grown In Sindh, Pakistan

Fourteen wheat varieties (Kiran-95, Amber, Sindh-90, Sarsabz, Khirman, Jauher-18, Mehran-89, Anmol-91, TJ-83, GP-256, GP-205, Marvi, and Soghat) collected from Nuclear Institute of Agriculture (NIA) and one unknown from local market, were analyzed for quantitative determination of proteins in term of suitability of wheat variety for baking purpose and nutritional point of view. The crude protein in all varieties was found in the range 8-15%. ANOVA analysis of results revealed the significant variation (P<0.05) in crude proteins among the selected varieties of wheat with coefficient of variability 0.065-0.713. The highest concentration of total protein found in variety Anmol (15.42 ±0.03) while the lowest concentration was detected in Local wheat variety (8.28 ± 0.06). The all wheat varieties soluble and insoluble fraction were quantified; the range of albumin was found as 17.0-22.4%, whereas the globulin content was in the range of 5.0-7.82%. The values of glutenin were 43.0-50.43%, while gliadin comprised 21.63-27.80% of total protein. The ratio of gliadin/glutenin varied from 1.6-2.2, indicating good quality of wheat varieties for baking purposes and have good nutrition status. The variety Anmol ranked high and can be used for breeding purpose to enhance nutritional status of consumers.
Alterations of Hormonally Active Fibroblast Growth Factors after Roux-en-Y Gastric Bypass Surgery

Thirty-five morbidly obese patients underwent Roux-en-Y gastric bypass surgery (RYGB). In addition to weight loss, these patients showed significant improvement of insulin resistance and a reduction of hepatic fat content. Three months after surgery, the serum bile salts were slightly but significantly elevated, and the levels of the endocrine-acting fibroblast growth factor 19 (FGF19) and FGF21 were increased. FGF19 and FGF21 play a role as regulators of hepatic lipid and glucose metabolism. These results show that RYGB surgery improves metabolism and that this improvement is still apparent 3 months after surgery. Bile salts may play a key role in the improvement of metabolism after RYGB. Why serum bile salt concentrations are elevated after RYGB needs to be investigated.
The Effect of Strength Training on the Jump-Landing Biomechanics of Young Female Athletes: Results of a Randomized Controlled Trial

Objective: To investigate the effect of leg-focused strength training on the jump-landing mechanics of young female athletes. Design: Single-blind, randomized controlled clinical trial. Setting: University-based training program. Participants: Forty female athletes, 10 to 14 years old, were randomly allocated to intervention or active control. Interventions: Twice weekly training was performed by the leg strengthening group [intervention group (IG); n = 19] and the active control group (CG; n = 17), for 12 weeks. Control group participants performed upper body strengthening exercises. Main Outcome Measure: Jump-landing performance was assessed by a blinded observer using the Landing Error Scoring System (LESS). Results: There was no difference between the IG and CG postintervention (IG mean LESS score 6.0 ± SD 1.8 vs CG mean 6.1 ± SD 1.8; P = 0.85). Conclusions: Strength training of the legs does not seem to improve jump-landing abilities in young female athletes compared with active controls who strength-trained their arms. Clinical Relevance: Leg strengthening may not provide an advantage over arm strengthening for improving jump-landing movement patterns in young female athletes. This has implications for the design of conditioning programs if injury prevention is a goal.
Towards a healthy stomach? Helicobacter pylori prevalence has dramatically decreased over 23 years in adults in a Swedish community

Background In Western countries the prevalence of Helicobacter pylori (H. pylori) infection may be declining but there is a lack of recent longitudinal population studies. We evaluated the changing epidemiology over a 23-year period in Sweden. Materials and methods In 1989, the validated Abdominal Symptom Questionnaire (ASQ) was mailed to a random sample of inhabitants (ages 22–80 years) in a Swedish community, and 1097 (87%) responded. H. pylori serology was analysed in a representative subsample (n = 145). Twenty-three years later, the ASQ was mailed again using similar selection criteria, and 388 out of 1036 responders had an upper endoscopy with assessment of H. pylori and corpus atrophy status. Results The prevalence of positive H. pylori serology decreased from 37.9% (1989) to 15.8% (2012), corresponding to a decrease in odds of 75% per decade (odds ratio (OR): 0.25; 95% confidence interval (CI): 0.11–0.59, p = 0.001) independent of age, gender, body mass index (BMI) and level of education, with a pattern consistent with a birth cohort effect. The prevalence increased with increasing age (p = 0.001). The prevalence of H. pylori on histology in 2012 was 11.4% (95% CI 8.6–15.0). The prevalence of corpus atrophy on serology and/or histology in 2012 was 3.2% (95% CI 1.8–5.5); all cases were ≥57 years old. Conclusion The stomach is healthier in 2012 compared with 1989. H. pylori prevalence in adults has decreased over the last two decades to a level where clinical management might be affected.

Education-specific Tag Recommendation in CQA Systems

Systems for Community Question Answering (CQA) are well-known on the open web (e.g. Stack Overflow or Quora). They have been recently adopted also for use in educational domain (mostly in MOOCs) to mediate communication between students and teachers. As students are only novices in topics they learn about, they may need various scaffoldings to achieve effective question answering. In this work, we focus specifically on automatic recommendation of tags classifying students' questions. We propose a novel method that can automatically analyze a text of a question and suggest appropriate tags to an asker. The method takes specifics of educational domain into consideration by a two-step recommendation process in which tags reflecting course structure are recommended at first and consequently supplemented with additional related tags. Evaluation of the method on data from CS50 MOOC at Stack Exchange platform showed that the proposed method achieved higher performance in comparison with a baseline method (tag recommendation without taking educational specifics into account).
Inflammation and preterm birth

Preterm birth is the leading cause of neonatal morbidity and mortality. Although the underlying causes of pregnancy‐associated complication are numerous, it is well established that infection and inflammation represent a highly significant risk factor in preterm birth. However, despite the clinical and public health significance, infectious agents, molecular trigger(s), and immune pathways underlying the pathogenesis of preterm birth remain underdefined and represent a major gap in knowledge. Here, we provide an overview of recent clinical and animal model data focused on the interplay between infection‐driven inflammation and induction of preterm birth. Furthermore, here, we highlight the critical gaps in knowledge that warrant future investigations into the interplay between immune responses and induction of preterm birth.
60 GHz Indoor Propagation With Time-Domain Geometric-Optics

60 GHz is one of the potential candidates in frequency spectrum for high-speed wireless communication. Geometrical optics in frequency domain (FDGO) is suffered from relative low accuracy and time consumption for frequency sweeping. In this paper, 60 GHz indoor propagation is studied with the time-domain geometric-optics (TDGO) method. The influence of slab walls with layered structures is considered. The accuracy of TDGO is validated by finite difference time domain. The result is compared with the results of FDGO and experiment in references.
Quantitative temporal proteomic analysis of human embryonic stem cell differentiation into oligodendrocyte progenitor cells

Oligodendrocytes (OLs) are glial cells of the central nervous system, which produce myelin. Cultured OLs provide immense therapeutic opportunities for treating a variety of neurological conditions. One of the most promising sources for such therapies is human embryonic stem cells (ESCs) as well as providing a model to study human OL development. For these purposes, an investigation of proteome level changes is critical for understanding the process of OL differentiation. In this report, an iTRAQ‐based quantitative proteomic approach was used to study multiple steps during OL differentiation including neural progenitor cells, glial progenitor cells and oligodendrocyte progenitor cells (OPCs) compared to undifferentiated ESCs. Using a 1% false discovery rate cutoff, ∼3145 proteins were quantitated and several demonstrated progressive stage‐specific expression. Proteins such as transferrin, neural cell adhesion molecule 1, apolipoprotein E and wingless‐related MMTV integration site 5A showed increased expression from the neural progenitor cell to the OPC stage. Several proteins that have demonstrated evidence or been suspected in OL maturation were also found upregulated in OPCs including fatty acid‐binding protein 4, THBS1, bone morphogenetic protein 1, CRYAB, transferrin, tenascin C, COL3A1, TGFBI and EPB41L3. Thus, by providing the first extensive proteomic profiling of human ESC differentiation into OPCs, this study provides many novel proteins that are potentially involved in OL development.
