Evaluation of the gingival condition and stress level of soldiers from the Brazilian Navy's Marine Corps during field training

The aim of this study was to evaluate the gingival condition and stress level of the military during field training. Thirty militaries were clinically evaluated at two times (1st and 10th - last day of the mission), by probing pocket depth (PPD), visible plaque index (VPI), and gingival bleeding index (GBI). After the clinical evaluation, the soldiers answered a stress questionnaire in both moments. The difference between the 1st and last day of the mission was verified by the Friedman and Wilcoxon tests and the correlation between stress x GBI and stress x VPI by the Spearman test (p<0.05). There was higher PPD (0.98mm), VPI (8.0%) and GBI (13.5%) on the last day of the mission, when compared to the first (PPD = 0.92mm; VPI= 5.2% and GBI = 10.2%), with significant statistical difference. Regarding the regions (anterior and posterior teeth), a higher VPI was observed in anterior (11.7%) than in posterior teeth (1.1%) on the first day (p=0.013); and in posterior teeth, between the first (1.1%) and last day (5.5%) (p=0.005). In the GBI, there was a difference for posterior teeth between the first (10.3%) and last day (14.9%) (p=0.004). One patient (3.3%) had initial symptoms of stress and,3 patients (10%) in the last day (p>0.05). There was no correlation between stress and gingival conditions. The military demonstrated a higher incidence of VPI and GBI at the end of the mission, especially in the posterior teeth. However, the stress was similar at the beginning and end of the mission.
Foundations of coverage in wireless sensor networks

Wireless sensor networks (WSN) promise to revolutionize the way we monitor our surroundings by enhancing our senses. Prototype systems are already being demonstrated. Several fundamental research issues, however, remain unaddressed. Sensing events being the main task of a WSN, appropriately addressing the issue of coverage is critical. In this dissertation, we make a two fold contribution on establishing a strong foundation for the issue of coverage. First, we argue that a single concept of coverage such as k-full coverage (where every point in the deployment region needs to be within the monitoring range of at least k sensors) does not fit all applications. We propose a new concept of coverage called k-barrier coverage that is appropriate for intrusion detection applications. A WSN provides k-barrier coverage if it guarantees that every penetrating object is detected by at least k sensors before crossing the barrier of sensors. Second, we address five foundational problems for the issue of k-barrier coverage: optimal deployment pattern, critical conditions, coverage status determination, coverage restoration, and optimal sleep wakeup. The problem of optimal deployment pattern is to determine a pattern of deployment that uses the minimum number of sensors. The problem of critical conditions is to derive conditions that can be used to determine the minimum number of sensors to deploy in probabilistic deployments. The problem of coverage status determination is to determine whether a deployed WSN provides a desired quality of monitoring. The problem of coverage restoration is to determine the minimum number of sensors to deploy, and their locations, such that a desired quality of monitoring can be restored in a deployed WSN. The problem of optimal sleep wakeup is to produce a sleeping schedule for sensors that maximizes the network lifetime. We comprehensively solve four of the five foundational problems. For the problem of critical conditions, we derive the conditions for a weaker notion of k-barrier coverage, called weak k-barrier coverage. In addition, we derive critical conditions for the case of k-full coverage.
“In Flow”! Why Do Users Share Fake News about Environmentally Friendly Brands on Social Media?

Social media has triggered an increase in fake news spread about different aspects of modern lives, society, politics, societal changes, etc., and has also affected companies’ reputation and brands’ trust. Therefore, this paper is aimed at investigating why social media users share fake news about environmentally friendly brands. To examine social media users’ behavior towards environmentally friendly brands, a theoretical research model proposed and analyzed using structural equations modeling in SmartPLS on a convenience sample consisting of 922 questionnaires. Data was collected by means of a quantitative-based approach via a survey conducted among social media users from an emerging market. The results show that social media flow has a mediated impact on sharing fake news about environmentally friendly brands on social media. Considering the critical consequences of fake news, the paper argues that understanding the dissemination process of this type of bogus content on social media platforms has important theoretical and managerial implications. Understanding the psychological mechanisms that influence people’s behavior in sharing fake news about environmentally friendly brands on social networking sites (SNS) could help in better understanding the factors and the effects of this phenomenon. The originality of this research consists of proposing flow theory from positive psychology to be used as a theoretical framework to explain users’ behavior of sharing fake news about environmentally friendly brands on social media.
STUDY OF AGE DETERMINATION BY HARJ PARTS OF ALBACORE FROM CENTRP. T. NORTH PACIFIC AND HAWAIIAN WATER~

Various hard parts of large (93-128 cm.) albacore, Genno alalu'nga (Bonnaterre), from Hawaiian waters and smaller fish (50-112 cm.) from the central North Pacific were examined for marks that could be used in determining age in this species. A cursory examination of the opercular bones and fin spines revealed no usable marks. A study of sC:lle samples. from 100 albacore showed that only one-half of them were readable, and these only with a considerable degree of subjectivity. Several workers in other areas have reported apparent success in aging albacore by means of the rings on the vertebral centra. Their results could not be duplicated in the present study. In attempts to read the rings in the vertebrae of 212 Hawaiian and 53 central ·North Pacific albacore, the authors found IiUle agreement. between the counts of the different readers or even betwcen successive counts by the samp. reader. Indications were seen that the rings on the vertebrae are no~ annuli but rather that they may be growth marks laid down randomly with time. As a clue to relative age, however, they may provide an explanation of the unbalanced sex ratio of large albacore, for they indicate the possibility that among mature fish the males grow faster than the females.Theresults of this study, though largely negative, are presented for the information of those engaged at present in similar studies and for others who may work on this problem in the future.
Immigration’s Identity Construction in Madrid’s Landscape: and

This article explores comparatively the strategies of construction and identity negotiation that the new ethnic and linguistic groups have reflected in Lavapiés and San Diego, two areas characterized by the highest percentage of international immigration, within Madrid. After the social and historical contextualization of both territories —to provide a more complete picture of its evolution— two collections of images or cartographies containing samples related to diversity in each territory will be analyzed from a methodological approach based on the exploratory analysis of the linguistic landscape. These parcours will allow to analyze the construction of multiculturality and otherness, which also goes hand in hand with seemingly opposite phenomena: from gentrification to a new definition of folk identity.
AdjuvantImmunization with Antigen and Mucosal Immune Responses after Mucosal NK Cells Influence Both Innate and Adaptive

NK cells were found to be recruited in a temporally controlled manner to the nasal-associated lymphoid tissue and the cervical lymph nodes of mice after intranasal immunization with Ag85B-early secreted antigenic target 6kDa from Mycobacterium tuberculosis mixed with Escherichia coli heat-labile toxin as adjuvant. These NK cells were activated and secreted a diverse range of cytokines and other immunomodulators. Using Ab depletion targeting anti-asialo GM1, we found evidence for altered trafﬁcking, impaired activation, and cytokine secretion of dendritic cells, macrophages, and neutrophils in immunized NK cell-depleted mice compared with control animals. Analysis of Ag-speciﬁc immune responses revealed an attenuated Ab and cytokine response in immunized NK cell-depleted animals. Systemic administration of rIL-6 but not rIFN- g signiﬁcantly restored immune responses in mice depleted of NK cells. In conclusion, cytokine production, particularly IL-6, via NK cells and NK cell-activated immune populations plays an important role in the establishment of local innate immune responses and the consequent development of adaptive immunity after mucosal immunization. The Journal of Immunology , 2010, 184: 4327–4337. The level of HRP associated with each well was then determined using Sigma Fast o -phenylenediamine dihydrochloride (50 m l per well; Sigma-Aldrich) colorimetric substrate. The reaction was stopped after 15 min by the addition of 2.5 M H 2 SO 4 . The optical density (OD) 490 was determined, and the titer was expressed as the reciprocal of the dilution giving an OD of 0.2.
VU Portal Keeping an eye on the violinist: motor experts show superior timing consistency in a visual perception task

Common coding theory states that perception and action may reciprocally induce each other. Consequently, motor expertise should map onto perceptual consistency in speci W c tasks such as predicting the exact timing of a musical entry. To test this hypothesis, ten string musicians (motor experts), ten non-string musicians (visual experts), and ten non-musicians were asked to watch progressively occluded video recordings of a W rst violinist indicating entries to fellow members of a string quartet. Participants synchronised with the perceived timing of the musical entries. Results revealed signi W cant e V ects of motor expertise on perception. Compared to visual experts and non-musicians, string players not only responded more accurately, but also with less timing variability. These W ndings provide evidence that motor experts’ consistency in movement execution—a key characteristic of expert motor performance—is mirrored in lower variability in perceptual judgements, indicating close links between action competence and perception.
Effect of Different Hot-Pressing Pressure and Temperature on the Performance of Titanium Mesh-Based MEA for DMFC

The hot-pressing process of the membrane electrode assembly (MEA) is one of the research hotspots in the field of the fuel cell. To obtain suitable titanium mesh-based MEA hot pressing process parameters, titanium mesh was used as electrode substrate material. The anode and cathode of MEA were prepared by the drip-coated method, and the titanium mesh-based MEA was prepared under different hot-pressing pressure and temperature, respectively. The performance of titanium mesh-based MEA was studied by morphological observation, elemental analysis, thickness measurement, single cell test and numerical fitting analysis. The results demonstrated that: with increasing hot-pressing pressure from 0 MPa to 10 MPa, the forming thickness of titanium mesh-based MEA is getting thin gradually, and the peak power density of titanium mesh-based MEA first increased and then gradually decreased; with increasing hot-pressing temperature from 115 °C to 155 °C, the peak power density of titanium mesh-based MEA enhanced at the beginning and then also gradually decreased. Under the premise of a hot-pressing time of 180 s and the optimal operating temperature of DMFC of 60 °C, the appropriate hot-pressing process conditions of titanium mesh-based MEA are a hot-pressing pressure of 5 MPa and a hot-pressing temperature of 135 °C. The results can provide a technological reference for the preparation of titanium mesh MEA for DMFC.
Learning Motivation as Predictor of Student Engagement in Private Junior High Schools Students

: Student engagement is an intensity of behavior, emotional quality and personal effort of active involvement of students in learning activities. When students engage in learning, they will participate and engage in academic and social activities and will have regulatory compliance and involvement in learning activities. Such students will possibly get good learning achievement. Motivating students to learn in school is a topic of great concern of educators today and motivating students that they can succeed in school is one of the greatest challenges of this century. Various studies have shown the linkage between student engagement and learning motivation. The aim of this research is to determine the effect of of achievement motivation toward student engagement mainly in coastal area of Surabaya.

Cardiac Cell Exposure to Electromagnetic Fields: Focus on Oxdative Stress and Apoptosis

Exposure to electromagnetic fields (EMFs) is a sensitive research topic. Despite extensive research, to date there is no evidence to conclude that exposure to EMFs influences the cardiovascular system. In the present study, we examined whether 915 MHz EMF exposure affects myocardial antioxidative and apoptotic status in vitro and in vivo. No statistically significant difference in the apoptotic cell profile and antioxidant capacity was observed between controls and short-term EMF-exposed mouse cardiomyocytes and H9C2 cardiomyoblasts. Compared with sham-exposed controls, mice subjected to a 915 MHz EMF for 48 h and 72 h had no significant effect on structural tissue integrity and myocardial expression of apoptosis and antioxidant genes. Therefore, these results indicate that short-term exposure to EMF in cardiac cells and tissues did not translate into a significant effect on the myocardial antioxidant defense system and apoptotic cell death.
PENet: Continuous-Valued Pulmonary Edema Severity Prediction On Chest X-ray Using Siamese Convolutional Networks

For physicians to make rapid clinical decisions for patients with congestive heart failure, the assessment of pulmonary edema severity in chest radiographs is vital. Although deep learning has shown promise in detecting the presence or absence or discrete grades of severity, of such edema, prediction of continuous-valued severity yet remains a challenge. Here, we propose PENet: Siamese convolutional neural networks to assess the continuous spectrum of severity of lung edema from chest radiographs. We present different modes of implementing this network and demonstrate that our best model outperforms that of earlier work (mean AUC of 0.91 over 0.87), while using only 1/16-th the dimension of input images and 1/69-th the size of training data, thus also saving expensive computation.
Clinical and haematological profile of dengue among adult patients at a tertiary care hospital in Pokhara

Introduction: Dengue is an important infectious disease. This disease is prevalent in the terai belts of Nepal mainly. But in the last few years, the cases are in increasing trend in the hilly areas of Nepal also. Hence this study was done in an aim to study the clinical and haematological profile of the dengue cases. Methods: This was a retrospective cross-sectional quantitative study done at a tertiary teaching hospital of Pokhara, Nepal after obtaining ethical approval from the institutional ethical committee. The data of serologically confirmed dengue cases, during the period of August 2019 to December 2019, of age above 15 years, were collected and analysed using SPSS 20. Descriptive analysis in terms of mean, median, percentage as well as t-test for nominal and chi-square tests were used to compare different parameters. P-value[≤] 0.05 was considered statistically significant. Results: Out of 922 patients, approximately one-half (50.5%) cases were seen during the month of September. Most (82.8%) were the inhabitants of Kaski district. Median age of presentation was 29 years with slightly more cases of males (52.4%). Three hundred and forty seven patients were admitted. Fever (96.5%) and headache (40.6%) were the most common symptoms on presentation of admitted cases. Leukopenia (55.3%) was more common than thrombocytopenia (47.6%) in the admitted cases. On comparison between admitted patients with warning signs and those without signs, no significant variation was seen in terms of age, total leukocyte count and total platelet count. Conclusion: Dengue is common in young population. Fever, headache and gastrointestinal symptoms are common among dengue patients. Leukopenia and thrombocytopenia are common laboratory features of dengue.
Determination of Unbound Partition Coefficient (K puu ) and in Vitro-in Vivo Extrapolation for SLC13A Transporter-Mediated Uptake

Unbound partition coefficient (K puu ) is important to understand the asymmetric free drug distribution of a compound between cells and media in vitro, as well as tissue and plasma in vivo , especially for transporter-mediated processes. K puu was determined for a set of compounds that are inhibitors and substrates of transporters from the SLC13A family in hepatocytes and transporter-transfected cell-lines. Enantioselectivity was observed with ( R )-enantiomers achieving much higher K puu (> 4) than the ( S )-enantiomers (< 1) in human hepatocytes and SLC13A5 transfected HEK293 cells. The intracellular free drug concentration correlated directly with in vitro pharmacological activity rather than the nominal concentration in the assay due to the high K puu mediated by SLC13A5 transporter uptake. Delivery of the diacid (PF-06649298) directly or via hydrolysis of the ethyl ester prodrug (PF-06757303) resulted in quite different K puu values in human hepatocytes (K puu of 3 for diacid vs. 59 for prodrug), which was successfully modeled based on passive diffusion, active uptake and conversion rate from ester to diacid using a compartmental model. K puu values changed with drug concentrations; lower values were observed at higher concentrations potentially due to saturation of transporters. K m of SLC13A5 was estimated to be 24 µM for PF-06649298 in human hepatocytes. In vitro K puu obtained from rat suspension hepatocytes supplemented with 4% fatty acid free BSA showed good correlation with in vivo K puu of liver-to-plasma, illustrating the potential of this approach to predict in vivo K puu from in vitro systems.
Theoretical study of the circuit architecture of the basic CFOA and testing techniques

ABSTRACT This paper examines the closed-loop characteristics of the basic Current-Feedback Operational Amplifier (CFOA), and in particular, the dynamic response. Additionally, it also examines the design and advantages of the CFOA regarding its ability to provide a significantly constant closed-loop bandwidth for closed-loop voltage gain. Secondly, the almost limitless slew–rate provided by the class AB input stage that makes it superior to the voltage-mode operational amplifier (VOA) counterpart. Additionally, this paper also concerns the definitions and measurements of the terminal parameters of the CFOA, regarded as a ‘black box’. It does not deal with the way that these parameters are related to the properties of the active passive and active components of a particular circuit configuration. Simulation is used in terminal parameter determination: this brings with it the facility of using test conditions that would not normally prevail in a laboratory test on silicon implementations of the CFOAs. Thus, we can apply 1mA and 1mV test signals from, respectively, infinite and zero source impedances that range in frequency from d.c to some tens of GHz. Also, we assume the existence of resistors with identical Ohmic value and very high value ideal capacitors. Where appropriate, practical test methods are referred to physical laboratory prototypes.
CD45RC Expression in the Rat T Cell Subsets Defined by the Level of Functional and Genetic Analysis of Two CD8

Differential cytokine production by T cells plays an important role in the outcome of the immune response. We show that the level of CD45RC expression differentiates rat CD8 T cells in two subpopulations, CD45RC high and CD45RC low , that have different cytokine proﬁles and functions. Upon in vitro stimulation, in an Ag-presenting cell-independent system, CD45RC high CD8 T cells produce IL-2 and IFN- (cid:1) while CD45RC low CD8 T cells produce IL-4, IL-10, and IL-13. In vitro, these subsets also exhibit different cytotoxic and suppressive functions. The CD45RC high /CD45RC low CD8 T cell ratio was determined in Lewis (LEW) and Brown-Norway (BN) rats. These two rat strains differ with respect to the Th1/Th2 polarization of their immune responses and to their susceptibility to develop distinct immune diseases. The CD45RC high /CD45RC low CD8 T cell ratio is higher in LEW than in BN rats, and this difference is dependent on hemopoietic cells. Linkage analysis in a F 2 (LEW (cid:2) BN) intercross identiﬁed two quantitative trait loci on chromosomes 9 and 20 controlling the CD45RC high /CD45RC low CD8 T cell ratio. This genetic control was conﬁrmed in congenic rats. The region on chromosome 9 was narrowed down to a 1.2-cM interval that was found to also control the IgE response in a model of Th2-mediated disorder. Identiﬁcation of genes that control the CD45RC high /CD45RC low CD8 T cell subsets in these regions could be of great of congenic lines in the rat model of that the aurothiopropanol sulfonate-induced immunological disorder (Aiid3) locus on chromosome
