Sexual Health: sexual knowledge, behavior and social determinants in the students of the University of Porto –a cross sectional study

Background: When considering sexual health, the youth is a particularly susceptible group. In Portugal, structured sexual education is available, however, 23.5% of new HIV cases in 2017 occurred in a population aged 15-29 years old. We attempt to understand the range of sexual health knowledge in youth, along with sexual behaviors and their influencing characteristics. Our main aim is to describe the relation between knowledge and sexual health-related behavior. Methods: This observational cross-sectional study involved an online questionnaire covering different areas of sexual health applied to students from the University of Porto, Portugal. This was used to create a knowledge and behavior score. Socio-demographic characteristics were used to examine associations with the scores. The relationship between the scores was assessed with Pearson’s bivariate correlation. Results: Out of 1815 questionnaires, 988 (54%) were validated. The mean score for knowledge was 3.74 out of 5 (95% confidence intervals [CI]: 3.69-3.77) and 3.4 out of 5 (95% CI: 3.38-3.44) for the behavior score. The knowledge score was influenced significantly by age and whether students frequented degrees in health-related studies. Only gender influenced sexual behavior. The correlation between knowledge and behavior was statistically significant with p<0.01 and a coefficient of +0.127. Conclusion/Discussion: Knowledge is an essential but insufficient determinant for health literacy. We urge the development of a sexual health prevention/education program which considers the interacting factors and motivates participants to integrate the assimilated information on a daily basis.
Memristive Equivalent Circuit Model for Battery

The design of mathematical models is based on conservation laws and also on the fundamental principles of modeling: structure, parameters, and physical meaning. Those kinds of modeling should have specific capabilities to deal with different working conditions and environments coping with challenges that include but are not limited to battery capacity, life-cycle, or the attempts to manipulate the current profiles during operation. Introducing memristive elements in batteries will be ideal to satisfy these fundamentals and goals of modeling, whereas addressing the recycling and sustainability concerns on the environmental impact by the placement of TiO2 memristor into this model can promote a recovery hierarchy via recycling and dispatching a slight amount to disposal as the previous focus was mainly concentrated on availability. As for battery materials, modeling, performing, and manufacturing all have proliferated to grasp the possible sustainability challenges inherited in these systems. This paper investigated electrochemical impedance spectroscopy to study this model and the dynamic behavior inside the battery. We found a solution to address the existing battery limitations that elucidate the battery degradation without affecting the performance, correspondingly by employing the dampest least-squares combination with nonlinear autoregressive exogenous for identifying such model and its associated parameters because of its embedded memory and fast convergence to diminish the influence of the vanishing gradient. Lastly, we found that this model is proven to be efficient and accurate compared to actual experimented data to validate our theory and show the value of the proposed model in real life while assuming Normal Gaussian distribution of data error with outstanding results; the auto-correlations were within the 95% confidence limit, the best validation was 2.7877, and an overall regression of 0.99993 was achieved.

Objective and design To investigate the healing mechanism of Delonix regia galactomannan (GM-DR) in a mice model of excisional cutaneous wound. Materials and subjects The wound healing effect of GM-DR was evaluated by the following parameters: wound closure, clinical signs (hyperemia, edema, exsudate, nociception), oxidative stress markers (malondialdehyde – MDA, reduced glutathione - GSH), histopathological and histomorphometric analysis (collagenesis, blood vessels, polymorphonuclear, mononuclear, �broblast/myo�broblast cells) and immunohistochemical (in�ammatory growth factor mediators).
Active Ageing: Dream or Reality

Noting the New Zealand Minister of Health's encouragement that occupational therapists assert their role in population health, Wilcock argues that individual therapists and the profession at large should support active ageing, both in their day-to-day practice and through political activism. Citing personal, historical and research evidence, and UN and WHO policy, she puts the case that only those older people who act against western cultural stereotypes of a sedentary old age can achieve healthy ageing. Occupational therapists, with their knowledge of health through occupation, are urged to support this vision as a matter of human rights.
US Navy Evaluation of the High Reynolds' Number Thermal Stability (HiReTS) Test Unit

Abstract : The HiReTS was developed by Shell Global Solutions, Fuels Business Group as a small- scale unit for evaluating the thermal stability of jet fuel prior to shipment to the consumer. The HiReTS was designed to operate at high fuel flow rates through a heated, stainless steel tube (capillary) representative of turbulent flow conditions in actual engine fuel injectors. At the standard operating conditions (SOC), the HiReTS has a Reynolds' Number (Re) of approximately 13,000, well within the turbulent regime. The presence of high turbulence in the HiReTS also eliminates the sensitivity of mass transport effects that occur in laminar flow test devices such as the Jet Fuel Thermal Oxidation Tester (JFTOT), which operates at a Re of approximately 10.
Single-leg cycling: a new training paradigm for improved bilateral cycling performance?

Purpose: a pilot study to examine the potential additive training stimulus of single-leg (SL) cycle training (4wk), upon double-leg (DL) cycling TT performance. Methods: 11 trained cyclists (2 female), with ≥4 yr experience (mean ± SD: 33 ± 10yr, 73 ± 5.6kg, W\(_{max}\) = 335 ± 33 W, VO2\(_{max}\) = 62 ± 5.9mL∙kg \(^{-1}\)∙ min\(^{-1}\)) were recruited. Cyclists performed a SL and DL VO\(_{2max}\)test, plus a \(^~\)30min simulated DL TT, before they were randomly assigned to either the DL or SL training groups. Cyclists incorporated 12 x1h sessions (under laboratory supervision) to their normal training. DL participants performed 6 x 5min at \(^~\)70% W\(_{max}\), with both legs simultaneously (1:1 rest). SL participants performed 12 x 5min at \(^~\)35% W\(_{max}\), alternating training leg every 5min (on modified cycle ergometers- the contralateral pedal loaded with a 10 kg counter-weight). All performance tests were then repeated. Results: Cycling time trial (TT) performance was improved similarly, regardless of the mode of cycle training intervention (both groups improved TT performance by \(^~\)4.1% (p<0.05)). DL VO\(_{2max}\) and W\(_{max}\)were only increased significantly in the DL trained group (both p≤ 0.01), by \(^~\)4.6% and \(^~\)3.0% respectively. No significant improvement in SL VO\(_{2max}\) was observed in either group. Conclusion: 4 wks of SL training did significantly improve DL TT performance in well trained cyclists, perhaps eliciting a differential training stimulus. Regardless, SL training remains to be proven significantly more effective than DL training of a similar duration and intensity.
Solids in Sewers: Characteristics, Effects and Control of Sewer Solids and Associated Pollutants

This Report presents information on the current state of knowledge of the origins, occurrence, nature and effects of sewer solids for use by engineers, scientists, administrators and water quality planners for the planning, design and operation of sewerage systems. The report addresses both sewer maintenance requirements and environmental protection issues. Increasing environmental standards, coupled with public expectations, have led to stringent water quality standards. In response to this, it has been necessary to develop new methodologies and computer based analytical techniques to model and understand the performance of all aspects of waste water systems. Fundamental to these techniques is the understanding of the way in which sewer solids contribute to the poor performance of wastewater systems and consequential environmental damage. The information presented in this Report about the origins, nature, movement, hydraulic and polluting effects of solids in sewers has enabled strategies and rules to be developed for the management of sewerage systems to minimise the deleterious effects of these solids and associated pollutants.

MACRO-MICROSCOPICAL ANATOMY OF THE GIZZARD OF EGYPTIAN LAUGHING DOVE AND ROCK PIGEON

This study aimed to maximize the acquaintance on the morphology of the gizzard of the Laughing Dove (LD) and Rock Pigeon (RP). Gizzards of ten birds of each species were used for gross anatomy, scanning electron microscope and light microscope. The gizzard was biconvex lens in shape with rhomboidal circumference in both birds and with more oval in LD. The gizzard length constituted 55.41% in LD and 53.60% in RP of the total length of the stomach. The gizzard extended from the level of the 5 th intercostal space to terminat12.25±1.18, 17.27±0.88mm behind the last rib and 10.90±0.70, 19.48±0.49 mm infront of the vent in LD and RP respectively. The midway section through the thick muscles in the dorsoventral plane parallel to the tendinous center showed that the gizzard lumen appeared nearly S-shaped at both birds with 2 invaginations at caudal end of the lumen toward the caudoventral blind sac of RP. Another midway section through the thick muscles and tendinous center in the dorsoventral plane explained that the gizzard lumen was nearly elliptical in RP and rectangular in LD surrounded in both sides by semi ellipsoid thick muscles. By SEM, the cutical folds of the gizzard resembled bundles of rods in LD and appeared as group of blunt projections in RP. The epithelial lining of the tubular glands was columnar with large rounded or oval nuclei and deeply stained basophilic cytoplasm.
Population dynamics of the carrot cyst nematode Heterodera carotae under greenhouse conditions

El nematodo del quiste de la zanahoria Heterodera carotae es un patógeno importante en Daucus carota. Para que las medidas de control sean efectivas, el conocimiento de la dinámica poblacional del nematodo a través del tiempo es indispensable. El presente trabajo, evaluó la dinámica poblacional de H. carotae en cultivo de zanahoria, durante 10 meses bajo condiciones de invernadero. En junio del 2017, se colocaron en invernadero 90 macetas (3 L volumen): 60 fueron llenadas con suelo naturalmente infestado con el nematodo (1200 J2/maceta) y las 30 restantes se utilizaron como controles (sin nematodos). En cada maceta, se sembraron 10 semillas de zanahoria. Después de la germinación, las macetas fueron muestreadas destructivamente cada 15 y 30 días (n=3). Las raíces de cada maceta fueron pesadas y posteriormente teñidas. Los quistes y J2 se extrajeron del suelo. Las poblaciones de J2 tanto en suelo como raíz, se comportaron de manera similar. En suelo, se observaron tres picos de J2 a los 105, 150 y 195 días con 735, 882 y 967 J2/200 cm3 de suelo respectivamente. Se calculó un factor de reproducción de 1.6 y se observaron cinco generaciones del nematodo. H. carotae causó una pérdida promedio en rendimiento de 70.8% durante el experimento. Los resultados pueden ser usados para desarrollar herramientas en la toma de decisiones para optimizar el momento de implementación de medidas de manejo.
Adaptive control of bucking on harvesters : Target and timing effects

Optimally bucking individual stems, based on market prices, is unlikely to provide log product yields that meet order book constraints at the harvest unit or forest level. Adaptive control, in conjunction with dynamic programming, has been shown in earlier research to provide superior results from stem and stand log bucking when the stand is subject to order book constraints. Adaptive control can be achieved by adjusting relative prices and small-end diameter specifications as the harvester progresses through the stand. In this paper, the simulated effects on overall apportionment degree of varying 1) target proportions for given log types and 2) update frequencies are examined. The results show that varying the target proportions provided the best overall apportionment degree in only one of four test Pinus radiata stands, compared with holding the target proportions constant. Also, no significant differences in apportionment degree were found when examining update rates from 4 to 512 stems in both of the two test stands. © Forest Products Society 2006.
Caring Behavior of Nurses Increase Level of Client’s Satisfaction in Clinical Area

Background: Nurse caring behavior is one aspect that is very related to nursing services, because caring includes human relationships and affects the quality of service and patient satisfaction. Patient satisfaction is the result of an assessment in the form of an emotional response (feeling happy and satisfied) to the patient because of the fulfillment of expectations or desires in using and receiving nurse services. Patient satisfaction is an evaluation or assessment after using a service that the selected service at least meets or exceeds expectations. The research design used is a descriptive correlational quantitative research method using a cross sectional approach; sampling technique is purposive sampling. The numbers of sampling were 41 respondents. Data collection instruments using a questionnaire Chi-Square test with a significance level α = 0, 05. Based on the Fisher’s Exact Test, p value = 0.018
Characterizing Multimodal Transfer Time Using Smart Card Data: the Effect of Time, Passenger Age, Crowdedness, and Collective Pressure

Understanding passenger transfer behavior is crucial to designing better multimodal transport networks and improving public transport service quality. However, obtaining data for modeling transfer behavior remains a challenge, in particular under complex facility configurations. The recent emergence of smart card data provides new and efficient data-driven approaches to modeling public transport systems. In this paper, the authors present the effect of time of day, day of week, age of passengers, crowdedness at stop/station and collective pressure in determining passenger transfer time. By analyzing transfer profiles provided by smart card transactions, they apply regression models to assess the impact of each factor in determining passenger behavior under different scenarios. Using morning peak period as a base category, they find that passengers are faster during morning peaks even though it is more crowded. In terms of age of passengers, they find that children and senior citizens generally transfer slower than adults. However, children may outperform adults in passing through an overpass. The crowding effect at a bus stop is not substantial unless passenger demand reaches its capacity, while the crowdedness at fare gantries always delays transferring. Finally, they identify the effect of collective pressure by using the number of fastest/slowest passengers around one individual as a proxy. A fast passenger around one individual is found to reduce his/her transfer time, while a slow passenger may delay the transfer significantly. This work presents some empirical evidence in understanding passenger transfer behavior in a multimodal transit network. The results could be incorporated into physical surveys to better model pedestrian behaviors, supporting convenient facility design and public policy making.
Advanced Pathway Guidance Evaluations on a Synthetic Vision Head-Up Display

NASA's Synthetic Vision Systems (SVS) project is developing technologies with practical applications to potentially eliminate low visibility conditions as a causal factor to civil aircraft accidents while replicating the operational benefits of clear day flight operations, regardless of the actual outside visibility condition. A major thrust of the SVS project involves the development/demonstration of affordable, certifiable display configurations that provide intuitive out-the-window terrain and obstacle information with advanced guidance for commercial and business aircraft. This experiment evaluated the influence of different pathway and guidance display concepts upon pilot situation awareness (SA), mental workload, and flight path tracking performance for Synthetic Vision display concepts using a Head-Up Display (HUD). Two pathway formats (dynamic and minimal tunnel presentations) were evaluated against a baseline condition (no tunnel) during simulated instrument meteorological conditions approaches to Reno-Tahoe International airport. Two guidance cues (tadpole, follow-me aircraft) were also evaluated to assess their influence. Results indicated that the presence of a tunnel on an SVS HUD had no effect on flight path performance but that it did have significant effects on pilot SA and mental workload. The dynamic tunnel concept with the follow-me aircraft guidance symbol produced the lowest workload and provided the highest SA among the tunnel concepts evaluated.
The TenTen Corpus Family

Everyone working on general language would like their corpus to be bigger, wider-coverage, cleaner, duplicate-free, and with richer metadata. In this paper we describe out programme to build ever better corpora along these lines for all of the world’s major languages (plus some others). Baroni and Kilgarriff (2006), Sharoff (2006), Baroni et al (2009), and Kilgarriff et al (2010) present the case for web corpora and programmes in which a number of them have been developed. TenTens are a development from them -- a new family of corpora of the order of 10 billion words. We describe how we are building them, what we have built so far, and how we shall continue maintaining them and keeping them up to date in the years ahead. While, as yet, they have very little metadata, we are working out how to gather and add metadata attribute by attribute. The corpora are all available for research at http://www.sketchengine. co.uk.
Investigation of a Zero-One Integer Programming Approach to Automating the Scheduling Process at the USAF Test Pilot School

Abstract : This thesis investigated models that could be used to determine a feasible schedule for the Test Pilot School (TPS) training program and form the basis for an automated scheduling system. The TPS problem is formulated as a 0-1 integer linear program and is solved using preprocessing techniques and the Branch-and-Bound algorithm. The method produced feasible solutions for small problems that equate to portions of the TPS schedule but cannot efficiently solve large problems like the full TPS problem. More investigation should be conducted to alter the method developed in the study so it could be used for large problems. A promising approach might be to develop a specialized Branch- and-Bound algorithm that uses the preprocessing methods discussed in the study.
Application of Long Distance Conveyance (LDC) of Dredged Sediments to Louisiana Coastal Restoration

Abstract : Restoration of Louisiana's marshes and other coastal habitats will, in many cases, require dredged sediments to provide suitable substrate. Potential restoration sites are often at great distances from the sediment source. It will require special efforts, commonly referred to as long distance conveyance (LDC), to pump sediment to the sites. For the purposes of this report, LDC projects are defined as those Louisiana coastal restoration projects that involve hydraulic transport of slurry (mixture of sediment and water) through pipeline distances of 16 km (10 miles) or greater. Pumping slurry through a long pipeline is a mature technology for bulk transport that has been used efficiently in specific applications like coal and iron ore transport. At the workshop entitled "Long-Distance Pipeline Transport of Dredged Material to Restore Coastal Wetlands of Louisiana," the consensus of panelists and the audience (that consisted of national and international experts in the field of long-distance transport of dredged sediment and other materials by pipeline) was that there were no fundamental technological challenges to the delivery of sediment via LDC (Hales et al. 2003). The engineering challenges will be to optimize LDC design, operation, and maintenance to achieve respective strategic restoration goals in the most efficient, cost-effective, and environmentally acceptable manner possible. Technical literature was reviewed and interviews with personnel involved in LDC-related projects conducted to summarize state-of-practice LDC dredging project information. Dredging and transport methodologies in relation to LDC state-of- practice are presented, and potential environmental impacts of long distance pipeline transport across wetlands are discussed. Scientific and engineering uncertainties related to LDC optimization of dredged sediment for coastal restoration are identified.
Monin-Obukhov similarity theory applied to offshore wind data - validation of models to estimate the offshore wind speed profile in the north sea

The offshore wind energy is gaining more and more importance in the scenario of the European renewable energies. Due to high costs of installation and maintenance, it is important to have a good assessment of the wind speed profile. The wind speed at the turbine hub level is used for energy yield evaluations and the knowledge of the wind shear helps estimating turbine structure loads. The wind speed profile in a marine environment is investigated using the data provided from the German offshore research platform FINO-1, the meteorological mast of the Dutch offshore wind park Egmond aan Zee and the weather forecast model COSMO-EU of the Deutscher Wetterdienst DWD. The data are compared to the Monin-Obukhov Similarity Theory using the Richardson Bulk Method, the Richardson Gradient Method and the Profile Methods. The results show that the models do not predict the wind speed profile well and large scatter is present. The weather forecast model COSMO-EU for offshore wind energy purposes is validated using FINO-1 measurements and the results are promising.
One-pot synthesis of camptothecin-loaded glutathione-responsive PEGlyation nanogels as novel antitumor therapeutics

PEGlyation nanogels have shown potential in cancer therapy due to their outstanding biodegradability and biocompatibility. In this study, glutathione (GSH)-responsive PEGlyation nanogels were loaded with camptothecin (CPT) (CPT@A2B5-PEG) by one-pot synthesis based on the monomers of disulfide-based diacrylate (A2) and N-(2-aminoethyl) ethane-1,2-diamine (B5). The nanogels with responsive cross-linked networks were degraded into small molecules according to their GSH-sensitivity. The nanogels were of the correct size as measured by TEM and DLS, and uptake into A549 cells was observed within 6 h. Cell viability assays showed that CPT@A2B5-PEG produced similar anticancer efficacy to free CPT. The GSH-responsive CPT-loaded PEGlyation nanogels produced by one-pot synthesis are therefore promising platforms for anticancer drug delivery.
