Morphological study of the field-aligned E-layer irregularities observed by the Gadanki VHF radar

We report on the ﬁeld-aligned irregularities observed in the low-latitude sporadic E-layer (Es) with the Gadanki (13.5 ◦ N, 79.2 ◦ E; geomagnetic latitude 6.3 ◦ N) VHF radar. The radar was operated intermittently for 15 days during the summer months in 1998 and 1999, for both daytime and nighttime observation. The total observation periods are 161 h for the nighttime and 68 h for the daytime. The observations were used to study the percentage of occurrence of the E-region echoes for both daytime and nighttime. The statistical characteristics of the mean radial velocity and spectral width are presented for three cases based on the echo occurrence characteristics and the altitude of observations (from 90 to 140 km ranges), namely, the lower E-region daytime (90–110 km), the lower E-region nighttime (90–105 km) and the upper E-region nighttime (105–140 km) echoes. The results are compared with that of Piura, a low-latitude station located at about the same geomagnetic latitude, but to the south of the equator. By comparing the behaviors of the lower E-region radar echoes of the summer months between Gadanki and Piura, we ﬁnd that the lower altitude echoes below about 100 km are rarely reported in Piura but commonly seen in Gadanki. Features of the nighttime echoes observed by these two radars are quite similar but daytime FAI echoes are again seldom detected by Piura.
Prognostic Value of a6(cid:1)34 Integrin Expression in Breast Carcinomas Is Affected by Laminin Production from Tumor Cells’

Immunocytochemical analysis of breast carcinoma speci-mens for a6(cid:1)4 integrin expression and other different pathobiological markers revealed (cid:1)34 integrin subunit expression in 36 of 80 cases analyzed and a significant association only with a6 integrin subunit expression (P < 0.01) and laminin production (P = 0.01) by tumor cells. Survival analysis indicated that 134 and a6 expression are associated with poor prognosis (P 0.02), whereas laminin production showed only borderline association (P = 0.06). However, analysis of disease outcome in relation to expression of both a6(cid:1)4 and laminin indicated best outcomes for patients with tumors producing laminin but not expressing a6(cid:1)34 integrin, whereas worst outcomes were observed for a6(cid:1)4-and laminin-positive tumors, indicating that a6(cid:1)4 expression was associated with prognosis, mainly in the laminin-producing tumor subset These data indicate that the prognostic value of a6(cid:1)4 integrin expression is affected by laminin production from tumor cells and suggest that interaction between these two molecules mediates distinct signals that are important for tumor progression.
Avaliação do Ensino de Empreendedorismo entre Estudantes Universitários por meio do Perfil Empreendedor

Entrepreneurship is a socioeconomic phenomenon that has been valued for its influence on the growth and development of regional and national economies. The main promoter of this phenomenon are entrepreneurs, subjects endowed with multiple features that make up their profiles. They are dynamic and results oriented, benefitting from the fruits of their own personal efforts. Entrepreneurial education is highlighted as one of the most efficient ways to promote an entrepreneurial culture and train new entrepreneurs. However, some difficulty has been observed in assessing the effectiveness of teaching and learning this subject. The objective of this study was to analyze, by means of multivariate techniques, an instrument whose function is to measure the learning of Entrepreneurship, verifying the change in entrepreneur profiles of 407 college students participating or not in an entrepreneurial training process. The results showed that students who participated in Entrepreneurship educational training activities showed significant changes in their entrepreneurial profiles. The main contributions showed growth in the Self-realization, Planner, Innovative and Risks Assumed dimensions.
Contrasting the E¤ect of Iron Mobilization on Soluble Iron Deposition to the Ocean in the Northern and Southern Hemispheres

This study extends a comprehensive modeling study by Ito and Feng to investigate the e¤ect of iron mobilization in size-segregated particles on soluble iron deposition to the open ocean using a global aerosol chemistry transport model. The iron dissolution from relatively insoluble iron in mineral aerosols due to chemical reactions with acidic species is calculated from the online simulation of our aerosol chemistry model. In addition, the iron from combustion sources such as biomass and fossil fuels burning is readily released into solutions in aerosols assuming constant iron solubility (i.e., the mass fraction of dissolved to total iron). The simulation results indicate that ﬁne particles play a major role in soluble iron supply to the Paciﬁc and Atlantic oceans in the Northern Hemisphere (70–100%) due to acid mobilization. In signiﬁcant portions of the Southern Ocean, in contrast, the amount of acidic trace gases is not high enough to promote the iron dissolution in the ﬁne aerosols. Consequently, coarse particles are important source of soluble iron in the South Atlantic Ocean (40–60%) downwind of regions from Patagonian desert in South America. The model response of soluble iron deposition to perturbation by iron solubility suggests that large ﬁres may supply a potentially important source of soluble iron to the open ocean, compared to dust.
THE IMPLEMENTATION OF THE SCIENTIFIC APPROACH THROUGH 5MS OF THE REVISED CURRICULUM 2013 IN INDONESIA

In 2013, the Indonesian government implemented a new curriculum, namely Curriculum 2013 (C-13). The C-13 applies scientific approach in the learning process. This research aimed at depicting teachers performance in implementing the scientific approach with 5Ms in schools, including observing ( Mengamati ), questioning ( Menanya ), experimenting ( Mencoba ), Reasoning ( Menalar ), and communicating the results ( Mengomunikasikan ). This survey research was conducted in the years of 2013-2015 in eight senior high schools, involving 8 principals/vice principals, 16 biology teachers, and 80 students, and in 100 observable lessons. The data in this study were collected using a questionnaire, interview and observation. The data were subsequently analysed with descriptive quantitative. The results indicate that the teachers strived in implementing the scientific approach through 5Ms. The percentage of teachers who were good category in conducting the scientific approach was as follows: (1) Observing (M1) was 22.7%, (2) Asking questions (M2) was 27.8%, (3) Doing experiments (M3) was 23.9%, (4) Reasoning (M4) was 7.9%, and (5) Communicating (M5 ) was 18%. Therefore, it was concluded that the teachers still needed more training in conducting the scientific process through 5Ms in the implementation of the revised curriculum.
An analysis of knowledge and attitudes of hospice staff towards organ and tissue donation

Background Only a minority of hospice patients eligible to donate tissue and organs choose to do so. Hospice care staff play a key role in discussions about donation, but their willingness to engage in these discussions and their understanding of issues around tissue and organ donation is poorly understood. Aims To (i) identify factors associated with the wish of hospice doctors, nurses and healthcare assistants to donate their own organs after death; (ii) survey the experience of discussing the subject with patients; (iii) determine staff members’ knowledge of organ and tissue donation and (iv) identify factors associated with knowledge of organ and tissue donation. Design Cross-sectional questionnaire survey of hospice care staff. Setting/participants 76 of the 94 care staff of one large UK hospice completed and returned the questionnaire. Results Staff wishing to donate their organs after death (43/76 56.6%) were more likely to be doctors or nurses than healthcare assistants (p=0.011) and more likely to have discussed organ or tissue donation with their family (p<0.001). Staff reporting ever having discussed donation with patients had more years’ experience (p=0.045) and had similarly discussed donation with their own family (p=0.039). Those with greater knowledge were more likely to have discussed organ or tissue donation with a patient (p=0.042). Conclusions A reluctance to instigate discussions about organ and tissue donation may prevent palliative patients and their families being allowed the opportunity to donate. Suboptimal knowledge among hospice staff suggests the need for greater liaison between hospice staff, and the organ and tissue donation teams.
Humour as coping and Flow as correlates of Subjective Happiness among Athletes and Non-athletes

This study intends to find out if humour as coping and flow could significantly be different among athletes and non-athletes, and if the above mentioned variables show any kind of relationship with subjective happiness. A sample of 62 athletes and 75 non-athletes aged between 16 and 22 were selected for the study. Inventories were used to collect the data. It includes The Subjective Happiness Scale (SHS) by Lyubomirsky (1999) , The Coping Humour Scale(CHS) developed by . A Martin (1983) and Flow State Scale by Jackson (1995). Demographic information including their age, gender, education level, and sporting involvement was also collected. The obtained results showed that Flow and humour are significantly higher for athletes than non-athletes. Flow and humour is also found to have a significant positive correlation with subjective happiness. Males are found to experience greater subjective happiness than females and they use more humour as coping. National level players experience more flow state than state level players. Second born children were found to be more happier than first born children. Thus within the limits and limitations of the present study results imply that engagements in athletic activities enhances humour coping and flow which contribute to better subjective happiness. programs that to performance and well-being. Results of the present study sheds on the effect of mindfulness training on athletes’ flow experiences during competitive sport training. Both the significant increase in global flow scores and the increases in the flow dimensions of clear goals and sense of control the effectiveness of the training Results offer promising for
SHAREHOLDER CONCENTRATION, BOARD STRUCTURE AND EXECUTIVE REMUNERATION

Understanding the dynamics of agency conflicts in Brazilian firms requires investigating the influence of shareholder concentration and board structure in the remuneration level of executives. Based on a sample of 232 firms traded on B3 between 2014 and 2016, we found shareholder concentration to have a negative effect on executive remuneration, as predicted by the agency theory. The characteristics of the board structure also have repercussions on executive compensation. Some of these characteristics affect the sensitivity of compensation to shareholder concentration, which, contrary to the managerial power approach, highlights the predominance of the principal–principal conflict in Brazil.
A new decade for social changes

Today's Kosovo economy, as well as that of the whole world, lives in an extraordinary dynamism, creating and using many new technical-technological and organizational achievements. The demand for innovation is a demand that, as soon as it is met, generates a demand for new innovation, a cycle that will not end. But what is the approach of some manufacturing and processing enterprises (small and medium) in the eastern part of Kosovo to innovation? The answer to this question is the purpose of this article. Research on innovations in Kosovo has been done before, but with a research focus in the district of Prishtina, but not in the eastern region of Kosovo, and there is a long time difference from recent research. The objective of this article is the current approach to innovation. The research was conducted through a face-to-face survey, in which 66 representatives of manufacturing and processing enterprises have participated. The analysis of the results, their comparison leads us to the conclusions and recommendations, information which can serve businesses, state decision-making structures and educational institutions, to compare theory and practice. The article gives to understand that continuous research in this area is an added value.
Long-term stability of intraoral vertical ramus osteotomy with or without pre-surgical orthodontics

The present study aimed to compare stability after surgery of skeletal and soft tissue between conventional surgery with pre-surgical orthodontics (CS) and pre-orthodontic orthognathic surgery (POGS) using intraoral vertical ramus osteotomy (IVRO). The present retrospective study included 31 patients with skeletal Class III malocclusions who had undergone bimaxillary surgery (Le Fort I osteotomy and bilateral IVRO). Patients were divided into the CS (n=14) and POGS (n=17) groups based on the presence or absence of pre-surgical orthodontic treatment. Lateral cephalograms were obtained before surgery, 1 day after surgery, 1 month after surgery, 1 year after surgery, and 2 years after surgery to evaluate skeletal and soft tissue changes between the 2 groups. The data were analyzed using chi-square tests, Mann-Whitney U tests, repeated-measures analyses of variance and independent t -tests. There was no significant difference in skeletal or soft tissue measurements — with the exception of the angle between the sella-nasion plane and the occlusal plane (SN-OP) ( P < 0.001) — between the CS and POGS groups at 2 years after IVRO. The SN-OP had increased in the CS group but decreased in the POGS group at 2 years after surgery. Therefore, these findings suggest that CS and POGS have similar long-term stability in patients with skeletal Class III malocclusion. Group comparisons were tested with an independent t test with Bonferroni correction. By repeated measures analysis of variance with Bonferroni correction. Positive and negative values indicate anterior and posterior horizontal changes, inferior and superior vertical changes, and increased and decreased dimensional changes, respectively. Group comparisons were tested with an independent t test with Bonferroni correction. measures of variance with Bonferroni correction. Positive and negative values indicate anterior and posterior horizontal changes, inferior and superior vertical changes, and increased and decreased dimensional changes, respectively.

Cardiovascular assessment in Female Spotted Paca ( Cuniculus paca )

 Aiming to provide cardiovascular morphophysiology information on the Cuniculus paca, an important neotropical rodent, eight healthy adult females of this species were evaluated three times by echocardiography under general anesthesia with isoflurane every 15 days. The exams were performed by a single experienced evaluator with the animals positioned in right and left decubitus. Posteriorly, two expert evaluators measured the cardiac chambers, walls and flow patterns, by B-mode, M-mode, and Doppler ultrasonography. The resulting values were compared among evaluators and periods by the Bland-Altman agreement test and several descriptive statistics were presented for each parameter. Echocardiographic images were obtained between the second and fifth left and right intercostal spaces, enabling the measurement of heart chambers and walls, mitral, tricuspid, aortic and pulmonary valves blood flows, and the ejection and shortening fractions calculation. None of the studied variables showed inter-observers or inter-periods variations. This study provided some normal echocardiographic variables, applicable to epidemiological, pathophysiological or case studies in the Cuniculus paca and phylogenetically close
Influence of electrical impedance and mechanical bistability on Galfenol-based unimorph harvesters

A study on iron-gallium (Galfenol) unimorph harvesters is presented which is focused on extending the power density and frequency bandwidth of these devices. A thickness ratio of 2 (ratio of substrate to Galfenol thickness) has been shown to achieve maximum power density under base excitation, but the effect of electrical load capacitance on performance has not been investigated. This article experimentally analyzes the influence of capacitive electrical loads and extends the excitation type to tip impulse. For resistive-capacitive electrical loads, the maximum energy conversion efficiency achieved under impulsive excitation is 5.93%, while the maximum output power and output power density observed for a 139.5 Hz, 3 m / s 2 amplitude sinusoidal base excitation is 0.45 W and 6.88 mW / c m 3 , respectively, which are 8% higher than those measured under purely resistive loads. A finite element model for Galfenol unimorph harvesters, which incorporates magnetic, mechanical, and electrical dynamics, is developed and validated using impulsive responses. A buckled unimorph beam is experimentally investigated. The proposed bistable system is shown to extend the harvester’s frequency bandwidth.
Helping Preschoolers Develop Phonemic Awareness Skills Using Sound Boxes

The purpose of this study was to examine the effects of sound boxes as a supplemental instructional technique on improving phoneme segmentation performance for a sample of preschoolers enrolled in a Head Start program. Sound boxes activity coupled with modeling, guided practice, and corrective feedback was implemented and gradually faded as students mastered phoneme segmentation skills. A multiple probe across participants design was used to compare children’s phoneme segmentation performance during baseline and sound boxes intervention conditions. All children’s performance on phoneme segmentation tasks during sound boxes intervention was above their baseline performance levels. Children were able to maintain their high phoneme segmentation performance levels after modeling, guided practice, and eventually the sound boxes were gradually removed. In addition, children were able to generalize segmenting some of the phonemes when they were presented within words that were not directly taught during sound boxes activity. Implications for using sound boxes in the classroom and at home are provided.
FWFA Optimization based Decision Support System for Road Traffic Engineering

Several ways and efforts have been already conducted to formally solve the road traffic congestion. However, the objective strategy type of road traffic engineering could not be proven truly. Try and error is one inefficient way in road traffic engineering to degrade the level of congestion. The combination between fuzzy-logic and water flow algorithm methods (called FWFA) was used as a main method to construct the decision support system (DSS) for selecting the objective strategy in road traffic engineering. The proposed DSS can suggest the most optimal strategy decision in road traffic engineering. Here, a main traffic road of Juanda in area Ciputat, Tangerang Selatan, province Banten, Indonesia; was selected as a research object in this study. The constructed DSS for road traffic engineering was structurally delivered in this paper.
Large mid-upper arm circumference is associated with metabolic syndrome in middle-aged and elderly individuals: a community-based study

Background The mid-upper arm circumference (MUAC) is a proxy for subcutaneous fat in the upper body and is a reliable screening measure for identifying individuals with abnormal local fat distribution. The purpose of this study was to evaluate the association between MUAC and metabolic syndrome (MetS) in middle-aged and elderly individuals. Methods We measured the MUAC in a cross-sectional sample with a total of 9787 subjects aged 40 years and older. The measurement of MUAC is performed on the right arm using a non‐elastic tape held midway between the acromion and the olecranon processes in duplicate, with the arm hanging loosely at the side of the body. The MetS was defined according to the Joint Statement of the International Diabetes Federation Task Force on Epidemiology and Prevention. Results MUAC was positively correlated with waist circumference (r=0.437, P<0.001), BMI (r=0.334, P<0.001), fasting insulin(r=0.348, P<0.001), HOMA-IR (r=0.134, P< 0.001), triglycerides (r=0.138, P<0.001), SBP (r=0.124, P< 0.001), and DBP(r= 0.123, P<0.001), and inversely correlated with adiponectin (r=-0.147, P < 0.001) and HDL-cholesterol (r=-0.176, P<0.001) after adjusting for age and gender. Compared with the lowest quartile group, the odds ratios were substantially higher for MetS (OR 1.77; 95% CI 1.51-2.09, P for trend<0.001) in the highest MUAC quartile group after adjustment for potential cofounder. Conclusion Large mid-upper arm circumference is associated with metabolic syndrome in middle-aged and elderly individuals .
