Interdisciplinary program on aviation weapon systems as a means of improving high school students’ attitudes towards physics and engineering

A unique interdisciplinary program entitled ‘Introduction to aviation weapon systems’ was developed and implemented at a leadingIsraeli high school that is affiliated with the Israeli Air Force. The program integrated physics and engineering and dealt with thestructure and principle of operation of weapon systems used in aviation. Twenty 12thgrade students majoring in mathematics andphysics participated in the program, whose objective was to enhance the students’ interest in physics and engineering, demonstratethe use of these disciplines in aviation, and to stimulate their desire to continue with more advanced studies in these subjects. Theresearch presented here used qualitative tools to characterize students’ attitudes towards the program, as well as changes in theirattitudes towards physics and engineering as a result of their participation in the program. Research results reveal that, in additionto the great interest the students exhibited towards the program, they believed that interdisciplinary learning that combines physicsand engineering leads to a better understanding of physics. The research also shows that, following the program, the students’interest in physics and engineering increased, as did their desire to continue with more advanced studies in the subject.
Increasing Energy and Performance Through Customer Passion: An Organizational Level Study

Abstract This study investigates the situations in which productive organizational energy (POE) and organizational performance increase through customer passion, that is, perceived customers’ affective commitment and customers’ positive word-of-mouth behavior. We integrate research on POE with research on customer influences on employees. Based on emotional contagion processes we develop hypotheses for the energizing influences of customers at the organizational level. We test the hypotheses using a dataset containing 495 board members and 8,299 employees of 152 organizations. The results show that customer passion is positively related to POE, which is in turn positively related to organizational performance. Furthermore, the findings indicate that the effect of customer passion on organizational performance through POE depends on top management team’s (TMT’s) customer orientation. By providing first insights into the linkages and contingencies of customer passion, POE, and organizational performance, this study puts forth a more holistic understanding of the energizing effect of customers on organizations.
Motivación, implicación en los deberes escolares y rendimiento académico

Este trabajo tiene como principal objetivo comprobar si hay diferencias significativas entre los estudiantes con rendimiento alto, medio y bajo en Matematicas y en Lengua Inglesa en el compromiso con los deberes y en algunas variables motivacionales vinculadas a las tareas para casa. La muestra esta integrada por 326 estudiantes de 4o, 5o y 6o curso de Educacion Primaria. Los resultados encontrados indican que los estudiantes con rendimiento alto estan mas motivados intrinsecamente, mas interesados en hacer los deberes y menos motivados extrinsecamente para realizar dichos deberes. Por otro lado, los estudiantes con niveles altos de rendimiento muestran, en general, una mayor implicacion en los deberes escolares, especialmente en lo que se refiere a la cantidad de deberes realizados y al aprovechamiento del tiempo dedicado a esos deberes. Sin embargo, en el caso de la asignatura de Matematicas, el tiempo dedicado a los deberes escolares por los estudiantes con mas alto rendimiento es ligeramente inferior al del grupo de estudiantes con rendimiento medio y al grupo con rendimiento bajo. Palabras clave: Deberes escolares, motivacion, rendimiento academico, Educacion Primaria. Motivation, involvement in homework and academic performance. The main objective of the present paper is to check whether there are significant differences among students with high, medium and low performance in Maths and English as regards their commitment in homework and several motivational variables. The sample consists of 326 students of 4th, 5th and 6th year of primary education. The results indicate that students with high performance are more intrinsically motivated, more interested in doing homework and less extrinsically motivated to complete their assignments. On the other hand, students with high levels of performance normally show greater involvement in homework, especially as regards to the amount of homework and the time spent to complete it. However, in the case of Maths, the time spent by students with high performance is slightly lower than the group of students with average and low performance.
V-type ATPase and pyrophosphatase in endomembranes of maize roots

Endomembrane fractions have been prepared from maize (Zea mays L,) roots. Electron microscopy and marker enzyme analysis indicate that they were highly purified. The endoplasmic reticulum (ER), the Golgi apparatus (GApp) and clathrin coated vesicles (CCV) were examined immunologically for the presence of V-type H + -ATPase and pyrophosphatase polypeptides. In addition, these organelles were tested for the respective two enzyme activities as well as their capacity to pump protons in vitro. Our results demonstrate that, although neither enzyme activity nor proton pumping were measurable, the polypeptides of the two electrogenic pumps are clearly present in all three membrane types
Visualization of Data Mining Techniques for the Prediction of Breast Cancer with High Accuracy Rates

Breast cancer is one of the leading causes of death in women worldwide. Around one in 30 women are affected by breast cancer. Mammography has helped in detecting breast cancer in the early stages which have reduced mortality. The diagnosis of breast cancer is dependent on a variety of parameters. In this paper, we aim to create the best model for predicting breast cancer through preprocessing, feature extraction, data visualization and prediction using breast cancer data. Various visualization techniques like violin plot, grid plot, swarm plot and heat plot were utilized for proper feature extraction which has improved the accuracy of our results. For the purpose of prediction, we have used algorithms like the random forest, decision tree with single and multiple predictors, along with the commonly used statistical model, logistic regression model. We have also relied on 5-fold cross-validation methods to measure the unbiasedness of the prediction models for performance reasons. An analysis of the models was carried out and the best model was selected based on its accuracy. The results showcased that the random forest model provided an accuracy rate of 94.724% with decent 5-fold cross-validation, followed by the decision tree model which had an accuracy rate of 100% with poor 5-fold cross-validation. This was followed by the logistic regression model which had an accuracy rate of 88.442% with a low 5-fold cross-validation score.
Effects of Turkish spice extracts at various concentrations on the growth of Escherichia coli O157:H7

Abstract The antimicrobial activities of the extracts of seven spices (cumin, Helichrysum compactum Boiss (HC), laurel, myrtle, oregano, sage and thyme) were examined in their capacity to inhibit the growth of Escherichia coli O157:H7. Spices were fractionated by the extraction method to obtain a methanolic fraction. Of the spices tested, thyme showed promising results by inhibiting growth both in paper disc assay and agitated liquid culture assay. Antibacterial effects of tested spices extracts vary related to concentrations. Thyme and oregano showed higher activity than the others. It was also found that laurel and HC markedly stimulated the growth of E. coli O157:H7. Statistically, important variations were found among the inhibitory effects of spice extracts. This study has shown that E. coli O157:H7 inhibition by spice extracts may be of use in the field of food preservation.

Double-Glycosylated Lysozyme at Positions 19 and 49 Constructed by Genetic Modification and Its Surface Functional Properties

Complementary DNA encoding hen egg white lysozyme (HEWL) was subjected to site-directed mutagenesis to introduce two N-linked glycosylation sites (Asn19-Try20-Thr21 and Asn49-Ser50-Thr51) into both positions 19 and 49 by substituting Arg-21 with Thr and Gly-49 with Asn, respectively. The double-glycosylated lysozyme R21T/G49N was expressed in Saccharomyces cerevisiae carrying the yeast expression plasmid inserted the double-mutant HEWL cDNA. The mutant lysozyme mainly secreted a polymannosyl form with a small amount of two oligomannosyl forms. The polymannosyl lysozyme R21T/G49N was glycosylated at two positions, 19 and 49, with a polymannosyl and an oligomannosyl chain. The lengths of the polymannosyl and oligomannosyl chains attached to R21T/G49N were approximately 272 and 18 mannose residues, respectively. The R21T/G49N showed better emulsifying properties than two types of single-polymannosyl lysozymes R21T and G49N. With regard to single-polymannosyl lysozyme, G49N showed somewhat better emulsifying .
Disconnect: Contradictions and Disagreements in Faculty Perspectives of Information Literacy

ABSTRACT Broward College, an early adopter of Guided Pathways, has made efforts to incorporate information literacy throughout the curriculum by embedding librarians in pathways and through General Education learning outcomes. However, although college administrators and faculty acknowledge that the integration of information literacy instruction throughout the curriculum is crucial to student success, librarians have struggled to become true teaching partners. A survey was administered to discipline faculty to determine attitudes, perceptions, and a self-assessment of information literacy. This study includes a nuanced analysis of discipline faculty responses and reveals conflicting attitudes and behaviors related to information literacy instruction.
The palaeohistology of pterosaur bone: an overview

The study of pterosaur bone histology dates back to the middle of the 19 th century, with the pioneering microscopical studies of BOWERBANK (1848) and QUEKETT (1849a, b, 1855) on UK material. In recent years, well-preserved bone material from the Romualdo Member of the Santana Formation, Brazil, has become available for histological study, but specimens from other localities have also proved informative. Most pterodactyloid bones are predominantly composed of highly vascular reticular fi brolamellar bone, similar to that of most extant birds. Lines of arrested growth are uncommon. This suggests that pterosaur bones grew rapidly, usually without interruption, until skeletal maturity was attained. Like birds, pterosaurs had very thin-walled bones, which possessed various histological and micro-architectural features to resist structural failure. These features should be taken into account in biomechanical studies of the pterosaurian skeleton.
Review and Reclassification of Cataglyphis (Hymenoptera, Formicidae).

Exactly 100 years ago Forel made a misidentification of Cataglyphis viaticus as C. megalocolus, one of the most characteristic insects of North Africa. This farreaching error has influenced the systematics of the genus ever since. What really are the species of Cataglyphis? Cataglyphis is unique among formicine ants in that the morphology of the male genitalia is highly diverse: their characteristics are used for the differentiation of species groups and as a basis for postulated phylogenetic relationships within the genus. A synopsis, a key to the species-groups, and a full catalogue of all the available names are given. Of the 104 taxa currently recognized as valid, Cataglyphis albicans var. mixtus is a new combination, Cataglyphis cursor ssp. flavicornis is transferred to Alloformica, and Cataglyphis mauritanicus and Cataglyphis nigripes are given a new status. Camponotus phaenogaster is a new synonym, and Cataglyphis hispidus is a nomen nudum. A lectotype has been fixed for Cataglyphis savignyi.
The human serum paraoxonase—Polymorphism and specificity

Human serum contains EDTA‐sensitive (Ca++‐dependent) and EDTA‐stable (albumin) paraoxonases which hydrolyse paraoxon, 0,0‐diethyl,0–4‐nitrophenyl phosphate. In Caucasians the EDTA‐sensitive enzyme shows a genetically determined polymorphism which is governed by two alleles. In typical Mongoloid or Negro populations this polymorphism is expressed to a lesser degree, and in a few samples (e.g. Aborigines) it cannot be observed at all. The distribution of the activity of the EDTA‐stable (albumin) paraoxonase is unimodal. Many authors supposed that paraoxonase is an arylesterase (EC 3.1.1.2) which means that it is also able to hydrolyse phenylacetate or β‐naphthylacetate. New investigations have shown that the human serum fractions splitting paraoxon can be separated from those hydrolysing phenylacetate and related substrates. The polymorphism of the EDTA‐sensitive human serum paraoxonase can be applied to investigations concerning specificity. From this it becomes evident that this enzyme is rather specific.
Differences in Style Length and In vitro Germinated Pollen Tube Length and Other Reproductive Structures of Tetraploid and Diploid Cottons

It was suspected that differences in style length and other reproductive structures of tetraploid and diploid cottons may contribute towards failure of crossing between two ploidies. Style length, stigma depth and pollen grain size of tetraploid were 20.5, 60.0 and 10.0 mm against 8.5, 2.0 and 7.0 mm of G. harknessii and 9.0, 2.5 and 7.0 mm of G. arboreum respectively. In vitro germinated pollen tubes of both the ploidy levels also varied significantly where tetraploid produced pollen tubes upto 20.5 mm long against 8 to 9.0 mm pollen tubes of both diploid species. It was therefore confirmed that style length is highly correlated with pollen tube length. Thus, shorter pollen tubes of diploid species are not expected to grow long enough in the longer styles of tetraploids and reach the ovary to fertilize it. Since, pollen grain size and stigma depth are also considered as food reserves for pollen tubes to grow into the styles and the differences in these structures can also be accountable to the failure of fertilization between the ploidy levels. Based on these results, it can be predicted that differential reproductive structure could at least be partially responsible for crossing failure and reciprocal crosses may be tried for successful fertilization.
Impact of patient photos on detection accuracy , decision confidence & eye-tracking parameters in chest and abdomen images with tubes and lines

To minimize errors in imaging studies, a camera system was developed that acquires images of patients simultaneously with radiographic images. 37 chest/abdomen portable radiographs showing central lines, orogastric/nasogastric/endotracheal tubes with patient photographs were viewed by 6 radiologists while eye-position was recorded. They indicated whether each line/tube was present/absent and rated confidence. Images were shown in 3 conditions: radiograph only, small or large photograph with radiograph. There was greater accuracy in detecting nasogastric and orogastric tubes with photographs present. Central lines had the most false positives but showed reduction with photographs. Decision confidence for central lines did not differ by image format, but for all tubes confidence without a photograph was significantly lower than with. For total viewing time there was a significant difference with no photograph format having the lowest viewing time followed by radiograph + large and radiograph + small photograph. For total number of fixations there was a significant difference with no photograph having the lowest number followed by radiograph + large and radiograph + small photograph. There was a significant difference in number of times observers transferred viewing from radiograph to photograph, with large photographs having fewer cross-overs than small. Adding patient photographs to radiographic interpretation of chest and abdomen films can aid in the detection of tubes/lines. If photograph size is large enough, it takes an average of only 3 extra seconds to view compared to the radiograph alone and adds significant confidence to decisions.
Multicentre pilot randomised clinical trial of early in-bed cycle ergometry with ventilated patients

Introduction Acute rehabilitation in critically ill patients can improve post-intensive care unit (post-ICU) physical function. In-bed cycling early in a patient’s ICU stay is a promising intervention. The objective of this study was to determine the feasibility of recruitment, intervention delivery and retention in a multi centre randomised clinical trial (RCT) of early in-bed cycling with mechanically ventilated (MV) patients. Methods We conducted a pilot RCT conducted in seven Canadian medical-surgical ICUs. We enrolled adults who could ambulate independently before ICU admission, within the first 4 days of invasive MV and first 7 days of ICU admission. Following informed consent, patients underwent concealed randomisation to either 30 min/day of in-bed cycling and routine physiotherapy (Cycling) or routine physiotherapy alone (Routine) for 5 days/week, until ICU discharge. Our feasibility outcome targets included: accrual of 1–2 patients/month/site; >80% cycling protocol delivery; >80% outcomes measured and >80% blinded outcome measures at hospital discharge. We report ascertainment rates for our primary outcome for the main trial (Physical Function ICU Test-scored (PFIT-s) at hospital discharge). Results Between 3/2015 and 6/2016, we randomised 66 patients (36 Cycling, 30 Routine). Our consent rate was 84.6 % (66/78). Patient accrual was (mean (SD)) 1.1 (0.3) patients/month/site. Cycling occurred in 79.3% (146/184) of eligible sessions, with a median (IQR) session duration of 30.5 (30.0, 30.7) min. We recorded 43 (97.7%) PFIT-s scores at hospital discharge and 37 (86.0%) of these assessments were blinded. Discussion Our pilot RCT suggests that a future multicentre RCT of early in-bed cycling for MV patients in the ICU is feasible. Trial registration number NCT02377830.
Reproductive biology of the golden catfish, Horabagrus brachysoma (Günther, 1864), an endemic species of the Western Ghats, India

Summary To study the reproductive biology of Horabagrus brachysoma (Gunther, 1864), monthly samples were collected from the riverine stretches of Lake Vembanad during 2001–2002. The sexes can be distinguished only during the breeding season; male to female ratio in the exploited catch was 1 : 1.97. The mean LT at first maturity (L50) was 18.5 cm in females and 17.5 cm in males. Absolute fecundity varied between 1100 and 124 000, with a mean of 20 472. The ovary showed group synchronous development and the oocyte diameter varied between 0.13 and 1.63 mm. The relatively high fecundity and hardy nature of H. brachysoma may favour the expansion of this indigenous catfish throughout the culture systems.
